Abstract: The disclosure provides a method for realizing call priority access, which includes: a Mobile Switching Center emulation (MSCe) adds priority information of a current call into a message of establishing a terminal which is notified to a Media Gateway (MGW); the MGW obtains priority of the call; and the MGW applies for call-related resources for the current call, and performs call priority access processing according to the priority of the current call when the call-related resources applied for by the MGW are busy. The disclosure further provides a system for realizing call priority access. The solution of the disclosure enables the MGW to realize the call priority access in a priority access way when the MGW applies for call-related resources, enriches and improves call priority access service of a communication network, and has extensive application prospect.

Abstract: A method for triggering a Mobile Access Hunting (MAH) group intelligent service is disclosed in the present invention. The method comprises: a Mobile Switching Center (MSC) sends an analysis information request message for triggering a Called-Routing-Address-Available trigger to a Service Control Point (SCP), wherein said analysis information request message carries indication information of MAH group intelligent service; and after receiving the answer from the connection number, the MSC sends a called answer request message for triggering a T_Answer trigger to the SCP, wherein the called answer request message carries a destination number and redirection indication information, which instruct the SCP to perform charging. An apparatus for implementing said method for triggering MAH group intelligent service is also disclosed in the present invention. The present invention achieves the triggering and charging of MAH group intelligent service, thus enriching and extending MAH group services.
