Nokia Siemens Networks has successfully completed Release 4 system performance testing with China Mobile

Nokia Siemens Networks and China Mobile Communications Corporation (CMCC) have successfully completed performance testing of the 3GPP release 4 MSC Server System (MSS) from Nokia Siemens Networks. The MSS performed with outstanding results in the tests organized by CMCC, demonstrating the Nokia Siemens Networks solution’s capacity, stability and efficiency in data-delivery.
The MSC Server System, which is already widely used in commercial networks globally, showed remarkable stability in an overload test which included an continuous 12-hour, 150% data-overload simulation. Despite the simulated data overload, the system ran, on average, at under 35% of total capacity (CPU load). The “Call Success Rate” was higher than 99.999%, and SMS delivery boasted a 100% success rate.

The MSC Server System is a circuit core network architecture that supports GSM/EDGE, WCDMA and TD-SCDMA. Nokia Siemens Networks is the world leader in soft-switch solutions, providing the MSC Server System to over 140 customers worldwide. Nokia Siemens Networks is a leading GSM/WCDMA mobile supplier in the China area with almost 150 million mobile soft-switch lines serving mobile subscribers in the China market.
