Abstract
A wireless telecommunications system and method for basing the voice coder selection for the speech channel on the current location of the subscriber. Subscribers having a voice coder of less quality, such as a half-rate voice coder, can specify that while making or receiving calls in certain locations, e.g., from home or from the office, an improved voice coder should be allocated, such as the enhanced full rate voice coder. The location based voice coder selection can be implemented in either the mobile station itself or within the cellular network.
