CHANNEL ASSIGNMENT WITHIN A BROAD-BAND COMMUNICATION SYSTEM

摘要

Remote units (113-117) that wish to receive a multicast session, monitor a multicast advertisement message on a system broadcast channel to determine a session to receive. Once a remote unit (113-117) requests participation in the multicast event, a common supplemental channel (205) is assigned to the remote unit (113-117), and the multicast session is broadcast to all remote units (113-117) currently participating in the multicast event. The common supplemental channel (205) utilizes two unique spreading codes for channel assignment, with one of the spreading codes being a function of the multicast session address (501) that is broadcast by the server (120).
