It is still a new concept that dual card pair of G network awaits the opportune moment, it is a brand-new subdividing the market that has just appeared in recent years. Two years ago, CHINAUNICOM took the lead in introducing the bimodulus business that GSM, CDMA were switched over freely, later improved and awaited the opportune moment for the bimodulus pair again, could hold online at the same time of the cell-phone numbers of two different networks. At present, this company strengthens a pair of purchase efforts of awaiting the opportune moment of bimodulus day by day.

How to enable NFC on the Verizon BlackBerry Bold 9930 with leaked OS update

How to enable NFC on the Verizon BlackBerry Bold 9930 with leaked OS update

We reported a couple of weeks ago that Verizon was turning off NFC in its version of the BlackBerry Bold 9930. Most mobile network operators are, in fact, selling BlackBerry’s flagship device with NFC turned off at the software level so Verizon’s decision was no big surprise. However, we know our readers that wanted a BlackBerry Bold weren’t keen on the device having the NFC crippled by mobile network operators. We had a trusted source tell us that the near field communications experience wasn’t too great and the software wasn’t yet developed to support as many features as mobile network operators would have liked to have seen for a user’s first NFC experience. To cut a long story short, there are thousands of BlackBerry Bold 9930 NFC-enabled phones now in circulation that don’t have the ability to read tags or other associated capabilities.

Sprint: Adding iPhone Actually Lightened Our Load

Is the iPhone more data efficient than its Android rivals? Sprint CEO Dan Hesse says it is.
During an earnings call Wednesday, Hesse claimed iPhones use about half the network resources required by Android handsets, a feature that weighed heavily in the carrier’s decision to add Apple’s device to its portfolio.

“There is a misperception that our launch of the iPhone will increase the load on Sprint’s 3G network and require us to spend more 3G capital,” Hesse said. “The reverse is true. iPhone users are expected to use significantly less 3G than the typical user of a dual-mode 3G, 4G device. Even adjusting for more total new customers being added to the network, we believe they will put less load on our 3G network than they would have if we did not carry the iPhone.”

China's telecommunications decide C network purchases the scheme: 3 years and 100 million two times 80 billion

The scheme that China Telecom purchased CDMA relevant assets to CHINAUNICOM was decided at last.

According to the final agreement that both sides signed on July 27, the group of China Telecom of parent company of China Telecom will provide funds of 66,200 million yuan to purchase CDMA network assets to UNICOM parent company, and the middle telecommunication listed company provides funds in centripetal UNICOM listed company of 48,300 million yuan and purchases the business of CDMA, after the aforesaid is purchased and finished, lease CDMA network and launch the business to run from hitting the centripetal telecommunication parent company of listed company of telecommunications.

On July 28, also as hitting Wang Xiaochu of a Chairman and CEO two major important post of telecommunications, and connect “ cross the shelf ” Go to China Telecom to take the post as president and concurrently COO (chief operating officer) Bing Shang,appear together, yes, Hong Kong.

According to Wang Xiaochu’s statement, “ a main and responsible one of mine is the overall strategy of the company, and total personnel check on, but concrete management is taken charge of by still president, implement strategy to the tactics specifically, this is division of labour of my Buddhist monk’s ice. ”

While accepting the interview including staff reporter, Wang Xiaochu says frankly, according to the present situation, China Telecom “ accepts C network and really faces a lot of challenges and pressures. ”

The pressure comes from and purchases the required huge capital expenditure too. By the look of final result, China Telecom has continued to use the mode that UNICOM deals in CDMA before this, namely the parent company buys the assets, and the listed company leases the network.

“From the viewpoint of listed company, obtained China CDMA network usufruct in a manner to pay the rental expense, not only can save the expenses reduce the investment risk of the listed company on the initial stage of managing, but also can, look while being long-term, with fast development of mobile service, realize network and unity of business run under appropriate condition, help to control the cost, reduce the related trade, manage the handling cost optimally, accord with shareholder’s long-term interests, ” Wang Xiaochu claim but when listed company will purchase CDMA assets to the parent company on earth, it is decided that “ to maximize the principle according to benefit and shareholder’s interests ” .

100 million for 3 years

Wang Xiaochu introduces, China Telecom purchases UNICOM CDMA business and moves and serves the whole journey to take three steps together in an all-round way.

Both sides sign the purchase agreement as the first stage formally to July 27 after from announcing on June 2 that purchases the preliminary chassis, mainly prepare and develop on network, products, IT system and industry chain; And the formal delivery one from October 1 to November 30, China’s telecommunications will begin to implement new movement service and customer to experience, and try commercially; By March 31 next year, 3G that China’s telecommunications will begin to popularize one’s own brand on a large scale will move and serve.

According to the data of the end of first quarter this year that UNICOM announce, UNICOM CDMA users are 42,810,000, account for 7.4% of the number of users of China Mobile, ARPU (the average telephone expenses income for each person every month) It is 53.3 yuan, the gross income of CDMA is 27,730 million yuan in 2007, accounts for 5.5% of China mobile communication market. EBITDA rate is 31.3%, pre-tax profit is 1,200 million yuan.

This is a figure not very optimistic. Especially key index ARPU, data display, ARPU value of CDMA, the high position of 172 yuan dropped year by year since 2002, have already fallen to 53 yuan by the end of first quarter of this year! And the number of users, 43,169,000 numbers of users of the first half of this year, only increase by 1,242,000 compared with the end of last year, accounts for 23% that increased 5,400,000 users newly last year.

By the look of the first half of this year, the operation figure of UNICOM CDMA is really not too goodlooking.

Whether will further worsen while completing a business transaction according to the purchase agreement in the future, Wang Xiaochu shows, “ I believe, CHINAUNICOM is a major company, it is a company with sincerity too, after our both sides sign the agreement, user, network when they have given to us by the end of September, including income and profit, I believe that will be the same as we purchase the situation confirmed at that time, level that should keep similar to the end of last year at least. ”

“In the following 2-3 years, we plan CDMA number of users and reach 100 million, market share is up to 15%, ARPU steadily increasing in value, value-added service account for than up to 35%. ” Wang Xiaochu claims.

Moreover, according to Wang Xiaochu’s plan, EBITDA of CDMA will turn negative number to positive number by 2009, will realize profits and become a full member in 2010.

This means, in the following 2-3 years, CDMA should increase by nearly 19 million at least every year on average! This figure will be 3.5 times of CDMA newly-increased users’ last year.

Likewise, the intersection of China and telecommunication plan, bring 15% up to, account for than up to 35% of market share from 5.5% present value-added service also. The end of last year, value-added service of UNICOM account for than 23% only, Wang Xiaochu claim China telecommunication value-added service of fixed net already up to 43% now.

After the telecommunication industry recombinates: The telecommunications of the foreign capitals move ahead while luring prudently

The telecommunication operator of the foreign capitals has been looking with covetously eyes to the market of telecommunication of China all the time, especially after telecommunications are recombinated, the new competition pattern brings the new chance to them. The news which the foreign capitals pool exists everywhere at one time. Recently, Australian dispatch wards off the path separately, has not pooled the Chinese telecommunication operator, but a huge sum of money is purchased indulges in serfing the Net and family, IT168 and CHE168 under command of the car amount to 55% share for four Chinese network matchmakers under command. All sorts of movements of the telecommunication operator of the foreign capitals, can find out them under the enticement that the pattern of market of China Telecom fluctuate, moving ahead prudently.

Look with covetously eyes

The recombination is an important step that the Chinese telecommunication industry reforms. Chance and upcoming 3G after the recombination, the telecommunication operators of the foreign capitals all wait for a chance to cause trouble, hope to join this ranks in various ways. News spreads Singaporean telecommunications and pools China Telecom for the previous period.

“We contact with every overseas family operator positively. But we have not said we negotiate with a particular operator of China. ” May invest in the news of the operator of China Telecom to the Singaporean telecommunications for the previous period, the relevant personage of the telecommunications of Singapore verifies to the staff reporter, have not reached and invested in the purpose with any telecommunication operator of China so far.

The rumor that Singaporean telecommunications pool China Telecom is not a groundless rumour. Wang Xiaochu, Chairman of China Telecom, has been revealing and keeping in touch with 4 to 5 potential strategy investors, and show that will not refuse any appropriate strategy cooperative partner. The efferent investors of the market include SK telecom, Singaporean telecommunication, high pass, Deutsche Telekom, Freneh Telecom and U.S.A. Verizon, AT&T,etc.. And South Korean telecommunication operator SK telecom president Xu ZhenYu shows “ Very interested to pool China Telecom ” .

“The number of users of China is too huge, certainly the appeal to foreign capitals operator is very great. It is an open listed company that the telecommunications of China run the commercial city, the chance that the foreign capitals participate in by shares is getting more and more. ” Electronic general manager of industry research center Jiang LiFeng analyses that have a match and guide a advisor and consume.

On one hand the foreign capitals operator has very dense thick interests, on the other hand it is the policy risk in view of China, their words and deeds are all very prudent. To the commitment of WTO according to Chinese Government, last year, the foreign businessman was moving, fixing the stock right of the telecommunication fields and all already allowing to rise to 49%, and two major fields have no restriction of region. But up till now, the foreign capitals operator is very low in one burst of proportions of Lignum seu Radix Acronychiae of Chinese operator, no exceeds 10%, the influence is still very small. So, are unsatisfied with this kind of state in wanting to enter the foreign capitals of the Chinese market very much.

“We do not become financial investors, seek strategic investment and cooperation relation, does not hope to just carry on the holding of the drib share. ” The above-mentioned Singaporean telecommunication personage tells reporters, the meaning between the lines is that new telecommunications are to hope that there be able to be shareholding or policy-making power to the investment strategy of overseas market, and there is deep cooperation of the aspect of business, but not merely hold a little shares. According to this, the mood entering China of new telecommunications is very urgent, but the difficulty of the negotiation is very great.

Change and “ turn towards ” Enter?

At the end of June, Australian telecom purchases and indulges in serfing the Net with 73 million dollars and family, IT168 and CHE168 under command of the car amount to 55% share for four Chinese network matchmakers under command. Today, the telecommunication operator of the foreign capitals slavered over market of China Telecom, Australian move of telecom seem some are intelligible.

“The threat of the maximum of telecommunication industry comes from Internet. ” Have a match and guide advisor’s senior vice-president Lu GuoYing to think, the telecommunication operator turns into three of the whole business operator after telecommunications are recombinated, their competition not only launch within them, the more important thing is it because of the integration of telecommunication, IT, Internet, Internet can snatch the customers of a lot of telecommunications, including personal customer and enterprise customer away directly.

Lu GuoYing tells reporters, when the telecommunication operator of the foreign capitals is doing the internationalization to expand, the overseas market generally inclines to take the way to control interest or develop independently. But because of the intersection of policy and barrier of China, it is very much difficult for this point not to realize. In the face of the huge market of China, adopt “ make changes according to specific conditions ” in China Way last choice.

In fact,with before some foreign capitalses of equity participation operator,if you can’t watch, make by business the cooperations of the aspects a key point too very much. For example when SK telecom pools CHINAUNICOM, both sides agree, the marketing, planning in CDMA network launches cooperation with the terminal respect of purchasing etc.. Moving shareholder’s Waduven of China, cooperates with China Mobile in fields such as LTE, moving Internet,etc. closely too.

Though how Australian telecom after not revealing works, Great Britain of Lu Kingdom thinks it enters the Chinese market by this kind of mode, will form the new challenge to the operator of China Telecom. “Internet can develop users independently, a lot of functions can substitute the telecommunications service. Because the policy barrier of Internet’s business is not as high as telecommunication, can purchase some valuable Internet’s business of China and enter the market at will in telecommunication of the foreign capitals. This will be an enormous challenge of the whole business operator of future. ”

Kasapa Rebranding To Expresso Telecom

Kasapa Telecom is rebranding to Expresso Telecom, two years after Hutchison Whampoa Group, its previous owners sold its interest to Expresso Telecom Limited, the Dubai Investment of Sudan’s Sudatel Telecom Group.

This is the second time Kasapa is re-branding. Kasapa, which was established in 1996 as Celltel re-branded to Kasapa in 2003. Kasapa currently has an estimated 400,000 subscribers, the least of all five operating mobile telecom operators in Ghana. Expresso has done an upgrade of Kasapa’s CDMA network to EVDO. This is expected to increase the network quality and bring faster data access to costumers.

Expresso has started running radio, tv and print media ads of its data service CliQ. CliQ offers EVDO USB modems at attractive and competitive rates. A CliQ EVDO USB modems sells at GHC 60 with 4.5GB data. Same price as MTN & Zain’s 3G modems but with 2GB and 500MB more data respectively.

Expresso Telecom already operates in Guinea, Mauritania, Senegal and Nigeria. Checking from the offers available to Expresso subscribers in Senegal, I expect Expresso Ghana to be a vibrant player in the a mobile telecommunication market which is seeing keen competition. Kasapa had the lowest call rate of 0.0925p/minute within network till Vodafone & Zain (Airtel Ghana) slashed their call rates to 8p/minute across all networks. I would want to see how Expresso will react to this.

I owned a Kasapa phone back in 2008. I gave it up because the service was terrible. I was getting charged for checking my voicemail, something which was advertised as free. In my opinion, the limiting factor to Kasapa’s growth is it being a CDMA network. There are a few CDMA handsets available here. The Ghanaian consumer wants to be able change SIMs and switch phones whenever. I just hope Expresso does their homework well and put out more classy CDMA phone on the market. I wouldn’t minding trying Kasapa again if I could get a Palm Pre or Pixi or an Android phone.

There is a lot of excitement in Ghana’s telecom sector now; Zain is also re-branding to Bharti Airtel, Glo mobile & the Glo-1 cable are going live soon, the MainOne cable is live and a price war is looming.

Welcome Expresso! Let’s see how you can ‘transform peoples lives to help unlock their potential through advances in a digital world’.

Evolution of Expresso Ghana

China's telecommunications decide C network purchases the scheme: 3 years and 100 million two times 80 billion

The scheme that China Telecom purchased CDMA relevant assets to CHINAUNICOM was decided at last.

According to the final agreement that both sides signed on July 27, the group of China Telecom of parent company of China Telecom will provide funds of 66,200 million yuan to purchase CDMA network assets to UNICOM parent company, and the middle telecommunication listed company provides funds in centripetal UNICOM listed company of 48,300 million yuan and purchases the business of CDMA, after the aforesaid is purchased and finished, lease CDMA network and launch the business to run from hitting the centripetal telecommunication parent company of listed company of telecommunications.

On July 28, also as hitting Wang Xiaochu of a Chairman and CEO two major important post of telecommunications, and connect “ cross the shelf ” Go to China Telecom to take the post as president and concurrently COO (chief operating officer) Bing Shang,appear together, yes, Hong Kong.

According to Wang Xiaochu’s statement, “ a main and responsible one of mine is the overall strategy of the company, and total personnel check on, but concrete management is taken charge of by still president, implement strategy to the tactics specifically, this is division of labour of my Buddhist monk’s ice. ”

While accepting the interview including staff reporter, Wang Xiaochu says frankly, according to the present situation, China Telecom “ accepts C network and really faces a lot of challenges and pressures. ”

The pressure comes from and purchases the required huge capital expenditure too. By the look of final result, China Telecom has continued to use the mode that UNICOM deals in CDMA before this, namely the parent company buys the assets, and the listed company leases the network.

“From the viewpoint of listed company, obtained China CDMA network usufruct in a manner to pay the rental expense, not only can save the expenses reduce the investment risk of the listed company on the initial stage of managing, but also can, look while being long-term, with fast development of mobile service, realize network and unity of business run under appropriate condition, help to control the cost, reduce the related trade, manage the handling cost optimally, accord with shareholder’s long-term interests, ” Wang Xiaochu claim but when listed company will purchase CDMA assets to the parent company on earth, it is decided that “ to maximize the principle according to benefit and shareholder’s interests ” .

100 million for 3 years

Wang Xiaochu introduces, China Telecom purchases UNICOM CDMA business and moves and serves the whole journey to take three steps together in an all-round way.

Both sides sign the purchase agreement as the first stage formally to July 27 after from announcing on June 2 that purchases the preliminary chassis, mainly prepare and develop on network, products, IT system and industry chain; And the formal delivery one from October 1 to November 30, China’s telecommunications will begin to implement new movement service and customer to experience, and try commercially; By March 31 next year, 3G that China’s telecommunications will begin to popularize one’s own brand on a large scale will move and serve.

According to the data of the end of first quarter this year that UNICOM announce, UNICOM CDMA users are 42,810,000, account for 7.4% of the number of users of China Mobile, ARPU (the average telephone expenses income for each person every month) It is 53.3 yuan, the gross income of CDMA is 27,730 million yuan in 2007, accounts for 5.5% of China mobile communication market. EBITDA rate is 31.3%, pre-tax profit is 1,200 million yuan.

This is a figure not very optimistic. Especially key index ARPU, data display, ARPU value of CDMA, the high position of 172 yuan dropped year by year since 2002, have already fallen to 53 yuan by the end of first quarter of this year! And the number of users, 43,169,000 numbers of users of the first half of this year, only increase by 1,242,000 compared with the end of last year, accounts for 23% that increased 5,400,000 users newly last year.

By the look of the first half of this year, the operation figure of UNICOM CDMA is really not too goodlooking.

Whether will further worsen while completing a business transaction according to the purchase agreement in the future, Wang Xiaochu shows, “ I believe, CHINAUNICOM is a major company, it is a company with sincerity too, after our both sides sign the agreement, user, network when they have given to us by the end of September, including income and profit, I believe that will be the same as we purchase the situation confirmed at that time, level that should keep similar to the end of last year at least. ”

“In the following 2-3 years, we plan CDMA number of users and reach 100 million, market share is up to 15%, ARPU steadily increasing in value, value-added service account for than up to 35%. ” Wang Xiaochu claims.

Moreover, according to Wang Xiaochu’s plan, EBITDA of CDMA will turn negative number to positive number by 2009, will realize profits and become a full member in 2010.

This means, in the following 2-3 years, CDMA should increase by nearly 19 million at least every year on average! This figure will be 3.5 times of CDMA newly-increased users’ last year.

Likewise, the intersection of China and telecommunication plan, bring 15% up to, account for than up to 35% of market share from 5.5% present value-added service also. The end of last year, value-added service of UNICOM account for than 23% only, Wang Xiaochu claim China telecommunication value-added service of fixed net already up to 43% now.

On the basis of the long-range control system design of CDMA 1X

A foreword

In the Off-The-Shelf industrial monitor system, commonly used information transmission mode is as follows, digital microwave, digital transmission radio station, wired optic fibre, have wire cables etc., digital microwave and digital transmission radio station will be the transmission distance and restriction that the frequency will be permitted, and wired optic fibre and the intersection of network and the intersection of cost and great to have wire cable, fit for controll point, disperse and transmit under the far situation using very much.

To control target disperse and every control among the node lacking organic connectioning, controlling information volume to be relatively less, the real-time nature requires that relatively low grade characteristic, CDMA 1X has offered a very good information transmission mode. CDMA 1X like to refer to the first stage (speed is higher than IS-95, lower than 2MB/s) of CDMA 2000 ,Can support the data transmission of 308kb/s, the part of the network introduces packet switch, can support to move IP business, it is a kind of new bearer service coming out in development in existing CDMA IS-95 system, the purpose is the formal data traffic of offering to CDMA user dividing into groups. Because CDMA 1X has adopted reverse coherent demodulation, new technologies such as power-controlling of fast forward direction, transmission diversity, Turbo code,etc., its capacity ratio IS-95 is greatly improved, according to analysis result of the theory, are used for conveying the speech business, the total capacity of CDMA 1X system is 2 times that of IS-95 system, used for conveying the data traffic, the total capacity of CDMA 1X system is 3.2 times that of IS-95 system, the bandwidth reachable 300kb/s of CDMA 1X theory, take spaciously to make an appointment about 100kb/s (transmit two-wayly and symmetrically) in present real application ,Offer TCP/IP to connect on this signal channel, can be used in application such as Internet connecting, data transmission. 2 wireless Communication based on CDMA 1X

2.1 Scheme of network connection

The wireless data transmission system is generally made up of data traffic centre, Communication network and data terminal, consider factors such as the data bulk of the business, safety, reliability, network state and cost,etc. synthetically, adopt the following network connection ways: The Communication server fixes IP or stationary domain name and inserts Internet, CDMA data terminal unit (DTU) with the public network Behind the power up, set up connection with Communication server voluntarily, if Communication server there is no fixed IP, can get the stationary domain name, it is stable that this scheme has low cost, Communication quality, the safety is moderate, characteristic of running reliably etc. through installing the shell software of peanut. 2.2 Wireless data transmission principle

According to the above-mentioned network connection scheme, the machine format up run transmits the principle as follows:

( 1) The lower-position unit passes the data to DTU through RS232 serial port;

( 2) DTU types the data into TCP/IP to wrap up, sends to The wireless network;

( 3) TCP/IP data packet passes the systematic packet data service node, transmit at Internet and go a designated data service centre that look for at Internet ’ Communication server) ;

( 4) The Communication server passes the data to the upper computer and stores to the historical database.

Machine format to fall and transmit it contrary to above-mentioned course, no longer go into details, the structure chart of system Communication is shown as in Fig. 1.

3 system design

3.1 The upper computer designs

The upper computer includes two parts of real-time monitor system and historical database. The real-time monitor system chooses InTouch systems of Wonderware Company, mainly realize the following functions: Systems management function; Data processing function: Including reporting the function regularly in data inquiry function, storage function of the data, data; Alarm function: Set feature service including handling the function, reporting an emergency and asking for help or increased vigilance in real time response function, linkage of reporting an emergency and asking for help or increased vigilance, reports an emergency and asks for help or increased vigilance and confirms the function, storage function of reporting an emergency and asking for help or increased vigilancing, operate control function, the historical database chooses Industrial SQL Server of Wonderware Company, mainly realize the following functions: Data statistics, report form function, historical data inquiry function, historical data curve chart, printing the function. 3.2 The lower-position unit designs

The lower-position unit chooses ABB AC31 series PLC, including CPU module and I/O module, CPU receives one or more appointed operation control commands of the Apparatus of control center, carry out corresponding operation control actions through the relevant apparatuses of I/O pair of module, and return and operate the result to the control center, the lower-position unit mainly realizes the following functions:

Data acquisition function, data inquiry function, report the function regularly, operate control function. 3.3 CDMA data transmission break

CDMA the intersection of data and transmission break choose the intersection of Shenzhen and great the intersection of electricity and technological the intersection of CDMA H7710 DTU and terminal to have the following characteristic this of Development Co., Ltd.:

( 1) H7710 DTU offers RS232/422/485 interface directly, offers transparent, full duplex, even data transmission channel for users’ der Datenaufbereiter. ( 2) Ordinary GPRS/CDMA Modem usually needs affixing to PC and dialing up on the telephone fictitiously, carries on data receiving and dispatching and protocol conversion with the resources of the PC, H7710 DTU built-in automatic network connected sum agreement puocessing module, do not need backstage supporter’s computer to support. ( 3) H7710 DTU can realize some - one, some - multi-point, the centre - data transmission of multi-point peer, transmission delay is generally smaller than 1s. ( 4) H7710 DTU can be affixed to GPRS or CDMA network automatically when beginning, and the data centre with you sets up the Communication link, receive and dispatch the data of user’s der Datenaufbereiter at any time. ( 5) H7000 mobile data Communication needn’t depend on the data interface unit of the operator switching center, cover the fictitious mobile data Communication private network of the whole of China through the construction whenever and wherever possible of Internet network. CDMA H7710 DTU must presume the parameter of meeting accident before inuse: CDMA 1X network lands user name and password, fixed IP address and domain name of the port or Communication server, online working way of DTU of Communication interface parameter, Communication server,etc.. 3.4 Design and realizing of the Communication server

The Communication server is a pivot of the overall system, mainly realize the data transmission between different agreements, the design of the Communication server is because of OPC standard, OPC can be interpreted as the connected sum embedding of the target of proceeding control (OLC for Process Control is a kind of technology used for application program interface that is developed under Microsoft’s operating system, because of Client/Server mode, in order to realize the Communication of the overall system, needs to hold 3 pieces of software on the Communication server; OPClink of Wonderware Company, IOServer of IOServer Company, CDMA Server. The management between working phase and every software of the Communication server is shown as in Fig. 2.

Tell the functions and application of 3 pieces of Communication software on the Communication server separately as follows.

3.4.1 OPClink

OPClink application software of work under the intersection of Windows and platform, main function to come, realize the intersection of OPC and server and the intersection of InTouch and the intersection of will and data transmission of sword Wu through protocol conversion. OPCLink all rightly and now or long run OPC server end software (IOServer, RSLinx) Connect, he converts the order of InTouch to OPC agreement then sends to OPC server end software, and read data fetch from OPC server end software, return to InTouch. Likewise, OPCLink can be connected to long run InTouch now too.

3.4.2 IOServer

The function of IOServer is the data transmission that is realized among different agreements, IOServer supports the following 14 agreements: Modbus agreement, AB agreement, ASCII agreement, Courier agreement, DNP agreement, GE agreement, HR6000 agreement, IEC103 agreement, KingFisher agreement, LoopBack agreement, Melsec agreement, Omron agreement, TI505 agreement, UCA2 agreement. In this system, what ABB PLC adopted is Modbus agreement, IOServer reads the data of ABB PLC from CDMA Server, and convert to TCP/IP agreement, convey to OPCLink.

The disposition of IOServer mainly includes 3 following parts:

( 1) Board (interface is disposed) : IOServer supports many kinds of interface, among them the most frequently used one is TCP/IP and serial port, while disposing the interface, need to define the agreement of the interface unit;

( 2) OPC Explorer: Offer the platform of built-in testing, can also observe and monitor the data.

( 3) OPC Gateway: Allow the data transmission between every OPC server based on different agreements, and the data transmission between IOServer and a certain control unit. 3.4.3 CDMA Server

In this system, uses VisualC ++6.0 to write CDMA Server software, CDMA Server is regarded as the Communication pivot of the overall system, include two parts of functions: Carry on the Communication with IOServer, carry on the Communication with DTU.

The Communication of CDMA Server and IOServer is based on SOCKET programming, adopts TCP/IP agreement to transmit, needs to set up port and IP address, IOServer sets up Communication through this port and IP address and CDMA Server.

The Communication between CDMA Server and DTU uses and develops the dynamic storehouse wcomm_dll.dll in the bag, this file includes and all required API functions of DTU communication, start, data transmission, die Datenannahme including being served, closing to serve etc..

It is user’s routine interfaces based on development tool kit that the Communication of OPC Server and DTU is designed, namely the dynamic linking storehouse cdmagprs.dll, this storehouse includes all required API functions of communicating with DTU, for example:

start_gprs_server: This function is used for starting the bottom layer to serve, after serve and start and DTU communication, after starting this service, there should be a function of the response message at the main window, so that and the bottom layer serves the communication.

stop_gprs_server: Stop serving;

do_read_proc: Read the data. Bottom layer serve, receive behind the data that DTU send, will to start, serve window file of DSC that appoint in the function, the intersection of news and response function in the window this should call read the intersection of data and function send DBU data read-out that come over immediately;

do_send_user_data: To DTU transmission data;

da_close_one_user: Close a DTU terminal station, make it roll off the production line;

do_close_all_user: Close all online DTU terminal stations, carry out this API before the general stop service.

Because Windows drives on the basis of news, after the bottom layer serves the data which receives distal DTU, will send one news to window to start function, so we can define one the intersection of news and response function come processing center and data transmission of DTU in procedure, in the response function of news, transmit data come through transferring die Datenannahme function and data transmission function in the dynamic linking storehouse, after data transmission finishes, the call closes and serves the function to finish the communication.

4 experiments and result analysis

The experimental procedure is as follows:

( 1) Set up DTU specification:

DTU identity heading code: 139 ********

Online report interval: 40s

Local Communication port: 5001

Maximum transmits Bao Chang: 1000B

Main DSC IP address: 219.229.3.24

( 2) Add users on CDMA Server, as shown in Fig. 3, among them set up unanimity on the terminal mouth and DTU, it is 5001. The gateway exports ports, namely CDMA Server and IOServer connecting port is set up as 5002.

( 3) Add port and Apparatus on IOServer, as shown in Fig. 4, in this system, because IOServer and CDMA Server are mounted on the same machine, so the IP address is set as 127.0.0.1, the port number corresponds to port that CDMA Server offers, namely 5002.

Through the above-mentioned step, have already set up Communication between IOServer and DTU, has continued only needing to dispose concrete Group and Item on IOServer and OPCLink, no longer go into details here.

This system has already been applied to the actual project, compared with wired data collecting system, this system has the following advantages:

( 1) Have reduced construction cost and maintenance cost of the Communication line;

( 2) Having improved the systematic flexibility, controling range is not limited by the region, the nodal control goal can be expanded arbitrarily.

( 3) The Communication line is more steady, not incident Communication trouble, even if go wrong, also can find and get rid of rapidly.

5 conclusions

Believe high-speed development and issue of 3G license plate of wireless Communication with CDMA, will lead the trend of The wireless communication, and the long-range monitor system based on CDMA wireless communication, there is more extensively employing.

After the telecommunication industry recombinates: The telecommunications of the foreign capitals move ahead while luring prudently

The telecommunication operator of the foreign capitals has been looking with covetously eyes to the market of telecommunication of China all the time, especially after telecommunications are recombinated, the new competition pattern brings the new chance to them. The news which the foreign capitals pool exists everywhere at one time. Recently, Australian dispatch wards off the path separately, has not pooled the Chinese telecommunication operator, but a huge sum of money is purchased indulges in serfing the Net and family, IT168 and CHE168 under command of the car amount to 55% share for four Chinese network matchmakers under command. All sorts of movements of the telecommunication operator of the foreign capitals, can find out them under the enticement that the pattern of market of China Telecom fluctuate, moving ahead prudently.

Look with covetously eyes

The recombination is an important step that the Chinese telecommunication industry reforms. Chance and upcoming 3G after the recombination, the telecommunication operators of the foreign capitals all wait for a chance to cause trouble, hope to join this ranks in various ways. News spreads Singaporean telecommunications and pools China Telecom for the previous period.

“We contact with every overseas family operator positively. But we have not said we negotiate with a particular operator of China. ” May invest in the news of the operator of China Telecom to the Singaporean telecommunications for the previous period, the relevant personage of the telecommunications of Singapore verifies to the staff reporter, have not reached and invested in the purpose with any telecommunication operator of China so far.

The rumor that Singaporean telecommunications pool China Telecom is not a groundless rumour. Wang Xiaochu, Chairman of China Telecom, has been revealing and keeping in touch with 4 to 5 potential strategy investors, and show that will not refuse any appropriate strategy cooperative partner. The efferent investors of the market include SK telecom, Singaporean telecommunication, high pass, Deutsche Telekom, Freneh Telecom and U.S.A. Verizon, AT&T,etc.. And South Korean telecommunication operator SK telecom president Xu ZhenYu shows “ Very interested to pool China Telecom ” .

“The number of users of China is too huge, certainly the appeal to foreign capitals operator is very great. It is an open listed company that the telecommunications of China run the commercial city, the chance that the foreign capitals participate in by shares is getting more and more. ” Electronic general manager of industry research center Jiang LiFeng analyses that have a match and guide a advisor and consume.

On one hand the foreign capitals operator has very dense thick interests, on the other hand it is the policy risk in view of China, their words and deeds are all very prudent. To the commitment of WTO according to Chinese Government, last year, the foreign businessman was moving, fixing the stock right of the telecommunication fields and all already allowing to rise to 49%, and two major fields have no restriction of region. But up till now, the foreign capitals operator is very low in one burst of proportions of Lignum seu Radix Acronychiae of Chinese operator, no exceeds 10%, the influence is still very small. So, are unsatisfied with this kind of state in wanting to enter the foreign capitals of the Chinese market very much.

“We do not become financial investors, seek strategic investment and cooperation relation, does not hope to just carry on the holding of the drib share. ” The above-mentioned Singaporean telecommunication personage tells reporters, the meaning between the lines is that new telecommunications are to hope that there be able to be shareholding or policy-making power to the investment strategy of overseas market, and there is deep cooperation of the aspect of business, but not merely hold a little shares. According to this, the mood entering China of new telecommunications is very urgent, but the difficulty of the negotiation is very great.

Change and “ turn towards ” Enter?

At the end of June, Australian telecom purchases and indulges in serfing the Net with 73 million dollars and family, IT168 and CHE168 under command of the car amount to 55% share for four Chinese network matchmakers under command. Today, the telecommunication operator of the foreign capitals slavered over market of China Telecom, Australian move of telecom seem some are intelligible.

“The threat of the maximum of telecommunication industry comes from Internet. ” Have a match and guide advisor’s senior vice-president Lu GuoYing to think, the telecommunication operator turns into three of the whole business operator after telecommunications are recombinated, their competition not only launch within them, the more important thing is it because of the integration of telecommunication, IT, Internet, Internet can snatch the customers of a lot of telecommunications, including personal customer and enterprise customer away directly.

Lu GuoYing tells reporters, when the telecommunication operator of the foreign capitals is doing the internationalization to expand, the overseas market generally inclines to take the way to control interest or develop independently. But because of the intersection of policy and barrier of China, it is very much difficult for this point not to realize. In the face of the huge market of China, adopt “ make changes according to specific conditions ” in China Way last choice.

In fact,with before some foreign capitalses of equity participation operator,if you can’t watch, make by business the cooperations of the aspects a key point too very much. For example when SK telecom pools CHINAUNICOM, both sides agree, the marketing, planning in CDMA network launches cooperation with the terminal respect of purchasing etc.. Moving shareholder’s Waduven of China, cooperates with China Mobile in fields such as LTE, moving Internet,etc. closely too.

Though how Australian telecom after not revealing works, Great Britain of Lu Kingdom thinks it enters the Chinese market by this kind of mode, will form the new challenge to the operator of China Telecom. “Internet can develop users independently, a lot of functions can substitute the telecommunications service. Because the policy barrier of Internet’s business is not as high as telecommunication, can purchase some valuable Internet’s business of China and enter the market at will in telecommunication of the foreign capitals. This will be an enormous challenge of the whole business operator of future. ”
