Methods of improving capacity for voice users in a communication network

摘要

In a method for improving capacity for voice users in a communication network and/or a method of avoiding channelization code starvation in the downlink when establishing a voice call with one or more users in the wireless network, two sets of channelization codes may be defined, each adapted for use with a corresponding first spreading factor and second spreading factor. One of the first and second AMR codec sets may be selected based on a comparison of a given number of available channelization codes for a voice call to a threshold, so as to encode voice data for transmission over an air interface.
