Title:
METHOD,SYSTEM AND RELATED DEVICE FOR PROCESSING CIRCUIT SWITCHED DOMAIN SERVICE IN EVOLVED PACKET NETWORK
Document Type and Number:
WIPO Patent Application WO/2009/089704
Kind Code:
A1
Abstract:
A method,system and related device for processing circuit switched domain service
in evolved packet network, the said method includes the steps of : a MME receiving
a MT service indication sent by a MSC (101); the said MME sending a MT service indication
to a UE(102); the said MME receiving a MT service response returned by UE(103),
processing the subsequent operation according to a MT service response(104).
In the method which provided by the present invention, the MME does not trigger
the switching which the evolved base station does to the packet switching service
of the UE, but informs the UE about the arrival of the MT service, and processes
the subsequent operation according to the MT service response returned by the
UE, thus the waste of network resources which caused by the unprovoked switching
of the packet switching service is avoided.
