METHOD AND APPARATUS FOR VOCODER RATE CONTROL IN A WIRELESS NETWORK

摘要

A packet filter function (220) in a wireless communication network (200) monitors congestion and communicates a congestion indication to one or more vocoders (210, 214). In one embodiment, the congestion indication comprises a vocoder source rate calculated by the packet filter function (220) in response to the congestion. The reduced vocoder source rate frees system resources that can be allocated to new users to alleviate the congestion. The vocoder source rate may be communicated to the vocoder(s) (210, 214) in a variety of ways.
