China Mobile Communications Corporation (China Mobile) is one of the telecom operators with the highest market value in the world and listed by FORTUNE TOP500 for 6 consecutive years. As of the mid of 2007, the number of users has exceeded 332 million. Through extended cooperation with Huawei, China Mobile build a excellent network of high-quality, long-term competitive capability and smooth evolution to IP.

High-quality network

With new construction and capacity expansion, the network structure has become more and more complicated, some equipment have aged and it is increasingly difficult to improve network and carry out new services.

Huawei‘s network adjustment solution successfully applied in Guangdong, Shandong, Jiangsu, and Zhejiang, Sichuan provinces.

For example, Chengdu is the capital of Sichuan Province, political and economical center of southwest in China. Market features a large population dense, a plenty of consumer quantity, high increase of traffic. These bring very high requirements for network expansion and adjustment. So far, Chengdu network adjustment project also is the largest network expansion and optimization project in the world.

Huawei's specialized networkplanning & optimization service and engineering team carried out construction and expansion for 1476 BTSs and 9 softswitchs in three months, and make a new record of cutting over 91 BTS in 3 hours. After the adjustments, network structure is simplified to enhance the capability of sustaining data service, improve network performance, and support the network to evolve to IP smoothly.

Long-term competitive capability

Along with 2G network expansion, how to combine with new technology to keep long-term competitive capability is a key problem that China Mobile have to faced.

Huawei innovatively introduce 3G and IP technologies into 2G system design. Abuntant 3G services are avaialble on the GSM network by adopting the future-oriented ALL-IP platform.
So many 2G users can enjoy abundant mobile-data services on the eve of 3G era.

Now, China Mobile network can support many similar 3G services including Mobile Phone Newspaper, Wireless Music Download, Fetion, CBRT, WAP. Experience of user and average revenue per user increased continually. The life-time of GSM network was prolonged greatly. In the fist half of 2007, the income that China Mobile generated from its value-added services reached RMB 42 billion, which represents an increase of 35.5%over the same period last year, and which accounts for 25.2% of China Mobile’s total operation income.

Smooth evolution to IP

In cooperation with Huawei, China Mobile deployed the world’s largest IP-based mobile softswitch core network in 2004, which makes China Mobile kick off the most important step to transform to telecom-grade IP field.

In 2007, China Mobile selected Huawei’s innovative IP BSS solution to upgrade and expand countrywide GSM network to ALL-IP network. Huawei’s IP BSS solution includes a new generation BSC (Base Station Controller) based on ALL-IP PARC platform(Platform of Advanced Radio Controller) and IP-based BTS (Base Transceiver Station) family.

The BTS family supports unified 2G/3G platform that can help operators replace old equipment andform future-oriented networks so as to protect their long-term investments. Moreover, Huawei’s IP-based mobile network solution solves three primary problems: synchronization、QoS and security via radio access network which is going IP.

Recently, China Mobile Shanxi branch applied the Huawei’s IP BSS solution, this solution fully used existing IP transformation resource of China Mobile Shanxi to bear voice and data service, not only save the cost of rebuilding TDM transformation, but also became the first IP BSS commercial network in the world, taking the mobile network transformation to IP.
