Huawei Completes Upgrade of China Mobile LD Network

Huawei Technologies has completed an upgrade to China Mobile's Long-distance network that that significantly improves voice quality and transmission resource efficiency. Financial terms were not disclosed.


In 2004, Huawei began working with China Mobile to deploy mobile softswitches for use as long-distance transit exchanges. That network is now carries 80% of all domestic long-distance traffic. With the extension of China Mobile's All-IP strategy to the local exchanges, it became possible to implement end-to-end voice over IP between the local softswitches and the transit softswitches. This change allowed the network to adopt AMR, a kind of audio coder & decoder technology, to improve the network capacity, lower operational costs, and provide a foundation for future network evolution.


Huawei provided professional network consultancy, network layout and engineering support during the network planning and the entire set of tasks for this project were successfully completed in one night. Services were smoothly transferred and network indexes continued to be normal. This change will allow China Mobile to flexibly control network bandwidth, and make the best use of network resources to meet future service needs.http://www.huawei.comhttp://www.chinamobile.com/
