MULTICAST DATA STREAM SELECTION IN A COMMUNICATION SYSTEM

摘要

An apparatus and method for multicast data stream selection in a communication system includes a first step (300) of providing an intermediate server between a service entity and mobile clients. A next step (302) includes receiving a join request from a mobile client. A next step (304) includes deriving subgroups with each subgroup having at least one associated multicast data stream. A next step (310) includes deriving subgroup outer tunnels. A next step (316) includes encoding different data streams for the associated subgroups. A next step (320) includes mapping each data stream to the respective outer tunnels for each subgroup. A next step (322) includes sourcing the mapped streams to each subgroup. A next step (324) includes converting the mapped streams to a form that can be recognized by the mobile clients.
