Processing circuit switched services in an evolved packet network
First Claim
1. A non-transitory computer readable medium storing instructions that, when executed by a computer processor, cause the processor to perform the steps of:
- receive information of a mobile terminated (MT) service from a mobile switching center (MSC), wherein the MT service is a circuit switched (CS) service;
send a message to a user equipment device (UE) in an evolved packet system (EPS) network to notify the UE of the MT service;
receive from the UE a MT service response; and
perform one or more subsequent operations according to the MT service response, wherein the MT service response indicates whether to accept the MT service, or reject the MT service.

Abstract
The present invention discloses for the ability for processing circuit switched (CS) services in an evolved packet network. For example, embodiments provide a method that includes: by a mobility management entity (MME), receiving a mobile terminated (MT) service indication from a mobile switching center (MSC); sending the MT service indication to user equipment (UE); and receiving an MT service response returned by the UE and performing subsequent operations according to the MT service response. In the method of the present invention, when an MT service arrives, the MME does not trigger the evolved NodeB (eNodeB) to hand over the packet switched (PS) services of the UE but notifies the UE of the MT service and performs subsequent operations according to the MT service response returned by the UE, thus avoiding the waste of network resources caused by a meaningless handover of PS services.
