METHOD AND SYSTEM OF CIRCUIT SWITCHED DOMAIN PAGE REALIZATION, METHOD OF SERVICE REALIZATION

摘要

A method and a system of circuit switched domain page realization are disclosed. After idle mode signaling reduction (ISR) function is introduced in packet switched domain, a scene of a called user equipment (UE) paged by the circuit switched domain includes: mobile switching center / visitor location register (MSC/VLR) saving one Gs association; When the circuit switched domain paging, the MSC/VLR sending a circuit switched domain page request message to a packet switched domain network element which is recorded in the Gs association; after the packet switched domain network element received the message, one or two circuit switched domain page being initiated in the packet switched domain and the circuit switched domain page being sent to the called UE; or the packet switched domain network element sending page response to the MSC/VLR that the circuit switched domain page is not initiated. A method of service information transferring is disclosed. The scene of activated idle mode signaling reduction function in the packet switched domain includes: the association packet switched domain network elements that is activated by ISR in UE sending service message each other to realize transferring service information.
