Abstract:
The present invention relates to a channel allocating method for an IP multimedia subsystem which connects a radio access network and an IP network to provide voice communication and non-voice communication. In the channel allocating method according to the present invention, an enhanced dedicated channel is allocated to a channel for voice communication in a radio uplink, so as to improve a utilization efficiency of radio resources (hardware resources) and to prevent degradation of network capacity, in the channel for voice communication in the IMS.
