METHOD OF DIVIDING MULTICAST GROUP IN CDMA 1X EV-DO SYSTEM

摘要

A multicast group partition method in a CDMA(Code Division Multiple Access) 1xEV-DO(Evolution Data Only) system is provided to be capable of periodically inserting multicast services into unicast services, therefore a synchronization problem and an exhaustion problem of a buffer can be solved. A diversifying module diversifies a group transmission rate by dividing a multicast group into plural groups through partition algorithm. A solving module periodically inserts multicast services into unicast services to solve a synchronization problem and an exhaustion problem of a buffer. A hierarchical encoding module solves the synchronization problem of the buffer between users having different transmission rates.
