1. A method of controlling a vocoder encoding rate for speech transmitted to a remote unit on a wireless channel, comprising:
- obtaining a usage value indicating an amount of the wireless channel that is in use based on how many users are accessing the wireless channel and a data rate transmitted by each user;
comparing the usage value with a channel usage threshold; and
selecting a vocoder encoding rate based at least in part on a result of the comparing.

Abstract
A method and apparatus are described for controlling the data rates for communications to and from a base station and a plurality of remote users. The usage of the communications resource whether the forward link resource (from base station to remote users) or reverse link resource (from remote users to base station) is measured. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.
