Siemens Shanghai Mobile Communications Ltd. (SSMC), as Siemen's mobile communication power house in the Asia-Pacific region, is making concerted efforts with Chinese cellcos, telecom manufacturers, and mass media to be committed to promote Mobile Business. In the past year, and the first half of the FY2000/2001 (October 2000 - March 2001) in particular, prideful achievements, centering on that target, were accomplished in succession. These include projects of deploying tandem offices for China Mobile and China Unicom, China Unicom's intelligent network, China Mobile's WAP gateway, GPRS implementation, capacity expansion for GSM networks of China Mobile and China Unicom, and establishment of Siemens Industrial Park, and being ISO 14001 certified. In addition, the first half of the year 2001 saw the globally simultaneous launch of the new eMicro base station, and the first trial with be with Shanghai Mobile before being employed for the informal meeting of 2001 APEC Summit. SSMC also joined hands with Shenzhen Unicom to deploy VPNs offering new services over intelligent networks.

Siemens planned a simultaneous launch of the new eMicro base station in China and the rest of the world and the first trial will be Shanghai Mobile before being employed for the APEC Summit

Siemens simultaneously launched its latest eMicro base station in China, one of the most important markets in the world, as well as other parts of the world. The new model will be firstly tested with Shanghai Mobile on April 12, and put into operation. The seventh capacity expansion Siemens invested several hundreds of million US dollars to Shanghai Mobile will see a seamless coverage of all the facilities in Shanghai Mobile's infrastructure within the Inner Ring of urban Shanghai this year. Superior communication environment will hence be created for the informal meeting of APEC Summit convened in October.

Meanwhile, the launch of eMicro meets the ever-changing market requirements. The fast-paced development of China mobile communication market resulted in the diversity and complexity of operators' requirements. While mobile subscribers demand stable and mature GSM networks, continued cost reduction is anticipated to meet what a full range of mobile communication services require. That is why in the field of wireless communications, deployment of new base stations that are highly flexible and future-proof hold the key to the operators' success in implementing multi-layered networks.

To be accurate, eMicro is nothing but an enhanced micro cell base station. It is of high quality and stable reliability, the very essence of Siemens' constant product design concept that has been followed, and what's more, its overall design is featured by highly flexible modular structure.

eMicro incorporates dual-carrier units (single DCU module). Each rack contains up to 4 carriers (2 DCU modules) and the same rack supports both single- and dual-band networks. The main rack with 4 carriers is allowed to further connect with another extended rack to provide up to 8 carriers. The maximum output power of each carrier at an antenna is 8 W. If stand alone carrier units are used with 4:1 or 2:1 built-in combiners, the maximum output power will be up to 14 W, rarely seen in products of this sort. That enables operators to freely select various special-purpose combiners, terrestrial interfaces (PCM24/30, microwave, NTPM and xDSL) and reserved modules for future-proof features in accordance with the specific conditions of the place to be used. They can be added simply by overlaying relevant modules to minimize the footprint of the racks a base station requires. It is impossible to fully integrate all the additional modules into a rack, to lay a solid foundation for its wide use and simplified upgrade in the future and save the time for on-site maintenance.

In addition to the above-mentioned features, other sophisticated features are countless. For instance, designers specifically prepare built-in standby power supply modules for eMicro to ensure high continuity as it is working outdoors. With a powerful EPROM in eMicro's core module, the software upgrade for the whole system can be done within one minute. The designing platform of EMicro supports full GPRS allowing a smooth evolution to EDGE (Enhanced Data rates for GSM Evolution) and UMTS (Universal Mobile Telecommunication System). All these features are well prepared for its wide and flexible use.

eMicro is flexible in practical use. It supports 8 assigned cells, 8 carriers and the maximum output power of each carrier is 14 W. Therefore, with additional external voltage controller, eMicro is able to reach the comprehensive coverage by macro cell base stations. The compact design makes it best suited for wall and pole-mounted, with no specific requirements for the room where it is. Even in some areas with unfavorable conditions for installation, because it supports both indoor and outdoor installation, together with its relatively small power loss and the extended range of normal operating temperature for equipment (-40oC--+55 oC). Wherever it is in place, it excels with its full advantages, that macro cell base stations could not compete. Moreover, the reception flexibility of this model is up to -114dBm, far exceeding the proposed -104dBM in GSM protocols, even outdoing some macro cell base stations available in the current market. eMicro is possibly mounted to the interior wall of the building where traffic is heavy aimed for a full coverage of the in-room space via external distributed antennas or leakage cables. eMicro can also be mounted to the exterior wall of the building for penetrating coverage of the adjacent buildings via built-in antennas or directional antennas to thoroughly eliminate the blind sectors for communications, caused by the obstruction of high-rise buildings and building materials. In hot spots with heavy traffic, such as shopping malls, high-grade office buildings, office buildings for administrative departments, where communications demands are huge, installation of eMicro allows effective diversion of heavy traffic from mobile users to a great extent in order to lower the blocking rate of busy hour calls. Combined with its flexible configuration and stable features, the coverage of multi-layered networks is truly realized. Quick, easy installation and commissioning plus excellent adaptability to any surroundings make eMicro an ideal solution for surging traffic in areas like large stadiums, international convention venues, exhibition centers, and important tourist attractions with medium or heavy traffic.
   
eMicro is used not only as a total and effective solution for the coverage that standard base stations could not cope with, but also a source from which a good variety of effective solutions can be derived for the highly changing requirements of today's networks. The benefits for operators are obvious, with proven applications in well known networks across the world, among them are TIM of Italy, Mobilfunk of Germany, Maxmobile of Austria, Netcom of Norway,
TCC of Taiwan. Facts speak louder. eMicro is believed to bring new experience of quality networks to China Mobile, China Unicom and their vast number of users.

Siemens to build a pilot VPN for Shenzhen Unicom
Strengthening partnership to cooperatively launch IN services

In March, Siemens Shanghai Mobile Communications Ltd. (SSMC) signed a contract with Shenzhen Unicom to jointly build a VPN expected to be complete in the first half of this year.

Intelligent network (IN) is one of the main trends of the current communication networks. The basic principle is a relative separation of service implementation and switching process. That is to say, the switching system manages the basic function of connection, while the creation of all the value-added services are perform by another network layer (i.e. intelligent network). The service designing platform with a graphic interface and service independent building block (SIB) enable fast creation of intelligent services. The introduction of IN standards (CAMEL) also standardizes IN interfaces, encourages fair competition which will definitely result in a cost reduction of products and benefit both network operators and end-users.

Multiple IN services are currently available over the IN platform. Besides prepaid services widely used in China, VPN service is a value-added service that operators prefer at present. VPN, on the basis of PSTN architecture, connects communications terminals at different places to create a logically closed user group based on users' requirements, specifications and the relevant software. It offers a wealth of options. VPN enjoys higher flexibility than leased lines. Creation of users, call barring, and even change of the network architecture, can be done merely by modification of software. Moreover, it saves a considerable amount of monthly rents for leased lines. VPN provides the corporate user a private numbering plan (PNP) with which each terminal used by employees will be assigned a corresponding abbreviated number, and a unified directory of such abbreviated numbers provisioned, enabling communications between employees by dialing abbreviated numbers.

Take the diversity of communication in the real world into account, INXpressVPN by Siemens integrates various terminals (mobile phones, fixed-line telephones, PABX terminals, fax machines that employees use) into the VPN service to unify various networks with IN platform.  In addition, it allows multiple access means. If an employee taking a business trip in the other place wants to call the company, he or she can dial the free number for remote access to get access into the corporate VPN after the proper authorization, with premium rate. VPN has great advantages in billing and cost control, as well as easy of use and preferential rates. INXpressVPN sorts out users to different member types with different classes to allow or disallow someone to make calls to the destinations out of the network. Or the caller should pay for such calls themselves. The setup of black list/while list strictly restricts employees to dial some numbers. INXpressVPN also delivers the rich function of call forwarding, to different terminals at different periods of time; or for the self-defined function of "follow-me", i.e. giving a terminal an abbreviated number at any time. Thus, the employee can be reached no matter where he or she is, by dialing that abbreviated number. InXpressVPN even allows quick definition of a number of business groups as a closed user group within the corporate VPN.

The spectacular growth of transmission capacity around the world and the favorable performance/cost ratio of VPN convinced a number of medium-sized companies or companies making international calls that VPN is more cost effective. According to the statistics, VPN service over intelligent networks in Europe claimed a one third share amid all the IN-based services in 1996, and the share has been increasing steadily, while US tops the world in that share proportion. Along with the quicker pace of opening up and economical development, Chinese medium- and large-sized enterprises show increased interests in VPN, which will lead the market in China in a few years, bringing more benefits to network operators and customers

SSMC had brilliant achievements in the first half of FY2000/2001
Good news poured in: implementation of WAP, GPRS, GSM, IN and tandem offices

Deployment of tandem offices
China Mobile
In October 2000, the initial appraisal of the third phase project for tandem offices in 13 cities jointly conducted by Siemens Shanghai Mobile Communications Ltd. and China Mobile was finished one after another and a general agreement reached. The project, starting in April 1999, is worth 300 million RMB, covering 13 cities including Taiyuan, Urumchi, Huhehot, Changchun, Lanzhou, Nanchang, Chongqing, Kunming, Shijiazhuang, Nanning, Haikou, Hefei and Guiyang. The projects of the first two phases were complete respectively in 1997 and 1998. The full completion of the project for China Mobile's tandem offices means that the construction of nationwide long distance mobile networks ends as a great success. The capacity and reliability of China Mobile's networks are significantly enhanced.

The whole project conducted by Siemens is divided into three stages. In the first stage (1996-1997), Siemens provided China Mobile with TMSCs to 8 key cities: Beijing, Shanghai, Guangzhou, Shenyang, Xi'an, Wuhan, Chengdu and Nanjing (one for each). In the second stage (1997-1998), Siemens provided the above mentioned cities another TMSC for each and other 7 cities a pair of TMSC. Thus, China Mobile has 15 provincial capitals or municipalities directly under the Central Government where a pair of TMSC installed. The third stage commenced in April 1999, The tandems offices in Shijiazhuang and Chongqing were firstly cut-over; on December 9, the cut-over in the other 11 cities were successful.

China Unicom:
In October 2000, Siemens Shanghai Mobile Communications Ltd. (SMCC) signed a contract with China Unicom in Beijing for the capacity expansion of primary tandem offices, involving 9 municipalities or provincial capitals like Beijing, Guangzhou, Shenyang, Shanghai, Jinan, Wuhan, Nanjing, Chengdu and Hangzhou. The contract is worth around 100 million RMB. The agreement successfully reached signals that the capacity and reliability of China Unicom's networks will be dramatically enhanced in the near future.

Siemens is the sole supplier for China Unicom's tandem offices. The first phase of Siemens conducted project for China Unicom's primary tandem offices, was complete in 1998.

IN project: Siemens will complete the third phase of a national project for China Unicom

In February 2002, SSMC and China Unicom reached all the agreements concerning the third project for the capacity expansion of China Unicom's intelligent networks. By the end of 2001, Siemens will accomplish, in three phases, the projects of intelligent networks within three years.

Siemens is the sole supplier for China Unicom's IN systems. The close partnership of Siemens and China Unicom resulted in a successful prepaid service based on Siemens' IN platform. The service has a strong presence in 21 provinces, municipalities and autonomous regions, and enables nationwide roaming. The full completion of the third phase IN project will increase the total number of users to 10 million. The contract concerning the first phase project for China Unicom's intelligent network was signed in May 1999, covering three cities of Beijing, Shanghai and Guangzhou. The contract for the second phase project was signed in January 2000, with coverage extending to three provinces in Northeast China, Guangdong and Guangxi, Jiangsu and Zhejiang, Sichuan and Chongqing, Anhui, Hubei, Shaanxi, Guizhou, Taijin, Hebei, Shandong, Henan, Shenzhen (21 China Unicom's branches in all). The coverage of the entire network was reached, and firstly launched by Shenzhen Unicom, with the capacity of prepaid users over 3 million. For the time being, Siemens is working with Shenzhen Unicom to roll out new VPN service to attract more corporate customers as a new revenue source.

GSM, WAP and GPRS: all-round partnership between Siemens and China Mobile

Siemens Shanghai Mobile Communications Ltd. became the leading supplier for China Mobile's WAP gateway systems. Siemens will complete the deployment of WAP gateway systems for Guangdong Center and Shanghai Center of China Mobile in the first quarter of this year, with the total capacity over 1 million. The secure end-to-end solution by Siemens is operator-oriented, and has high scalability. WAP gateway allows a smooth evolution in terms of configuration, the users supported will grow from 50,000 to 1 million. Meanwhile, the WAP gateway enables authorization of online users, so that an operator is capable of implementing effective tracing and management of online users.

In the first phase of deployment project for China Mobile's GPRS systems, Siemens Shanghai Mobile Communications Ltd. will upgrade the existing networks of Sichuan Mobile and Shanghai Mobile, with provisioning of 38 BSCs and 7 HLRs in all. The BSS equipment will be upgraded to the BR 5.5 version and new PCU modules inserted to each BSC to offer GPRS functionality. At the side of HLR (SR 8.0 version), GPRS functionality will be available only by the activation of Gr interface.

Siemens Shanghai Mobile Communications Ltd. and Shanghai Mobile Communications Corporation signed a one billion RMB contract concerning the seventh capacity expansion for the GSM900 network. Moreover, SSMC also works for Shanghai Mobile Communications Corporation to deploy networks along the Metro lines, and offers a three-year maintenance.

The cooperation between SSMC and China Mobile advances step by step. The technologies involved including maintenance and optimization of the existing GSM networks, deployment of WAP and GPRS-based mobile Internet, in such key areas like Guangdong, Sichuan, Tibet and Shanghai. The strength of Siemens, as an integrated telecom solution provider, is proven once more.
