Abstract
The invention provides a method, device, and system for obtaining user equipment (UE) location information. The method includes: an interworking entity (IWF) receives UE location information reported by a mobility management entity (MME); the IWF determines trusted UE location information according to the UE location information reported by the MME; and the IWF interacts with a UE or a mobile switching center (MSC) according to the trusted UE location information. With the method, device, and system, it is ensured that the MSC can obtain trusted and accurate UE location information in a circuit switched over packet switched (CSoPS) architecture.
Claims10
A method for obtaining user equipment (UE) location information, comprising:
- receiving, by an interworking function (IWF), a request sent by a UE for obtaining current UE location information;
- receiving, by the IWF, address information of a mobility management entity (MME) of a core network provided by the UE in a register procedure or register update procedure that is initiated to the IWF by the UE;
- storing, by the IWF, the address information of the MME;
- interacting, by the IWF, with the MME according to the address information of the MME obtain location information of the UE;
- and
- sending, by the IWF, the location information of the UE to the UE;
- wherein the interacting step comprises:
- sending, by the IWF, a request for the location information of the UE to the MME according to the address information of the MME;
- and
- receiving, by the IWF, the location information of the UE sent by the MME in response to the request sent by the IWF.
