Method, system and device for processing circuit switched services in an evolved packet network
First Claim
1. A method for processing circuit switched (CS) services in an evolved packet system (EPS) network, comprising:
- receiving, by a mobility management entity (MME), an indication of a mobile terminated (MT) service from a mobile switching center (MSC), wherein the MT service is a CS service;
sending, by the MME, the indication of the mobile service to a user equipment (UE) in the EPS network;
receiving, by the MME, an MT service response from the UE that comprises a user choice; and
determining, by the MME, according to the user choice, whether to trigger a process for the UE to hand over from the EPS network to a 2nd generation or 3rd generation (2G/3G) network to process the MT service.

Abstract
The present invention discloses a method, system and device for processing circuit switched (CS) services in an evolved packet network. The method 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.

14. A user equipment (UE) capable of communication in an evolved packet system (EPS) network, comprising:
-
a receiver, configured to receive an indication of a mobile terminated (MT) service from a mobility management entity (MME), wherein the MT service is a circuit switched (CS) service; a user interface, configured to receive a user choice regarding the MT service from a user of the UE, wherein the received user choice is used by the MME to determine whether to trigger a process for the UE to hand over from the EPS network to a 2nd generation or 3rd generation (2G/3G) network to process the MT service; and a transmitter, configured to send to the MME an MT service response that comprises the user choice. - View Dependent Claims (15)
