SESSION CONTROL METHOD FOR USE IN RADIO COMMUNICATION SYSTEM

摘要

A session control method for use in a radio communication system is provided. In the session control method, a session management(SM) protocol message for the setting or the cancellation of a session is transmitted with the aid of a radio resource control (RRC) protocol message of a lower layer for the setting or the cancellation of a radio bearer. Therefore, it is possible to reduce the number of signalling messages to a radio interface and thus to minimize signalling delays. In addition, it is possible to realize a many-to-one correspondence between services and bearers and realize efficient packet services in an evolved radio communication system by separately defining service identifiers and bearer identifiers and selectively setting or cancelling a bearer according to the correspondence between services and bearers.
