SHENZHEN, China -- On April 5th, 2004, China Mobile selected Huawei’s advanced GSM soft-switch MSC to build its TMSC plane network, which will cover the network of China Mobile in 31 provinces and branches, and also deal with all the long-distance mobile calls between two branches to save long-distance call transmission resources via IP transmission. It will support ‘17951’ VoIP services of China Mobile simultaneously. The contract includes over 30,000 E1 ports.

Huawei’s GSM soft-switch MSC is based on packet switch technology, and adopts advanced technologies; it can be shared by GSM and WCDMA, supports smooth evolution from GSM to WCDMA. Huawei‘s GSM soft-switch MSC is the new generation of GSM MSC.

The soft-switch GSM MSC is thus getting more and more popular. Compared with the traditional GSM MSC, it has much more advantages as shown below:

  • It adopts advanced soft-switch technology and supports VoIP, and saves transmission resources with IP transmission instead of TDM transmission.

  • It supports the R4 distributed networking function. R4 networking reduces CAPEX and OPEX and also improves network quality.

  • Complying with international standards and protocols, it supports all services and functions of GSM and with mere software upgrading, 3G services shall be supported in the future thus saving existing investment as the network develops.

  • It supports CAMEL 3 prepaid services (Voice and Data), VoIP, Ring back-tone services, Hot-billing, AoCC/AoCI, PTT, etc. And it is compatible with CAMEL 2 prepaid service downwards. What is more important is that it also supports smooth evolution to CAMEL 4.

  • High integration & low power consumption. Huawei’s GSM soft-switch MSC is not only highly integrated but also supports a large number of subscribers. It maximally supports 1.8M subscribers. High integration reduces network complexity, investment in equipment rooms, air conditioning and besides that it ensures system reliability and provides much easier maintenance. The amount of power consumed is immensely reduced to a mere 22 KW further realizing a reduction in operation costs thus making it the right choice for today’s telecom operators. It adopts a modular design, thus supports on-line capacity expansion and software upgrade.

  • Middle-ware Technology. Middle-ware technology means that the upper layer software is irrelative to the bottom layer operating system. The technology allows for cross interchange between different platforms and the little change in the service software enables the manufacturer to rapidly provide stable commercial versions. This technology can help operators increase services and functions with easy software upgrade.
