Method and system for a multicast service initiation in a communication background

摘要

In a communication system, a method for a multicast service channel assignment comprises broadcasting a multicast service notification, receiving at least one response to the broadcasted multicast service notification and assigning the multicast service channel in accordance with the received at least one response. If the number of responses exceeds a pre-determined threshold, a shared multicast service channel is assigned, and if the number of responses is below the pre-determined threshold, a dedicated multicast service channel is assigned.
