A METHOD, MULTICAST-BROADCAST DEVICE AND SYSTEM FOR A TERMINAL TERMINATING MULTICAST-BROADCAST SERVICE

摘要

A method, multicast-broadcast device and system for a terminal terminating multicast-broadcast service are disclosed. The terminal of WiMAX network can terminate normally MBS service. When MBS server receives the terminal termination request or when condition for terminating service provided for the terminal is satisfied, MBS server modifies context of the terminal, stops accounting and notifies network side key management entity to terminate key update for the terminal. If the terminal is active, after MBS server confirms that the terminal terminates MBS service, MBS server or anchor gateway notifies service gateway the termination information. Service gateway notifies a base station serving the terminal to modify user count corresponding to MBS and triggers bearer regulation procedure when user count satisfies preset condition. If the base station bears MBS service by PTP mode, after the terminal terminates MBS service, the base station releases resource corresponding to the terminal MBS.
