METHOD FOR IMPLEMENTING PRIORITY BASED CALL ACCESS

摘要

A method for implementing priority based call access is disclosed in the present invention. A Mobile Switching Center emulation (MSCe) encapsulates the priority level information of the current call into the message which notifies the Media Gateway (MGW) the creating of terminal. The MGW acquires the priority level of said current call; the MGW applies for the call related source of the current call, and processes the priority based call access according to the priority level of the current call when the call related source which the MGW applies for is busy. The present invention also discloses a system for implementing priority based call access. The solutions in the present invention enables the MGW to apply for the call related source according to the priority access, enriches and perfects the priority based call access services of the communication network, and has an extensive application prospect.
