Problems solved by technology

However, if the MSC stored in the HSS happens to be the identity of MSC1, such a processing method obviously causes MSC1 to send unnecessary signaling to the HSS, and it is easy to cause congestion in the HSS

Embodiment Construction

[0079] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0080] image 3 The flow chart of the method for implementing location update in the present invention, when the UE moves to the coverage area under the jurisdiction of the target mobility management unit, it will send a tracking area update request to the target mobility management unit to request registration in the new area, such as image 3 shown, including:

[0081] Step 300: During the context transfer process of the UE, the destination mobility management unit obtains the CS domain location information registered in the original system before the UE moves.

Abstract

The invention discloses a method for realizing position update and a mobility management unit. The method comprises the following steps that: a destination mobility management unit acquires circuit domain position information registered in an original system before movement of UE (User Equipment) in a context transmission process of the UE; and a destination MSC (Mobile Switched Center) initiates a position update request to an HSS (Home Subscriber Server) by using the acquired circuit domain position information registered in the original system before movement of the UE. Through the technical scheme provided by the invention, unnecessary signaling overhead is avoided; successful calling of the UE is ensured; and the congestion risk of the HSS is lowered.

Description

technical field [0001] The invention relates to technical mobility management technology, in particular to a method for realizing location update and a mobility management unit. Background technique [0002] At present, the standardization working group of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is working on the study of the packet switching core network (PS Core, Packet Switch Core) and the global mobile communication system radio access network (UTRAN, Universal MobileTelecommunication System Radio Access Network) evolution. The research topic is called System Architecture Evolution (SAE, System Architecture Evolution), the purpose is to enable the evolved packet network (EPC, Evolved Packet Core) to provide higher transmission rate, shorter transmission delay, to optimize packet and support Mobility management among evolved UTRAN (E-UTRAN, Evolved UTRAN), UTRAN, wireless local area network (WLAN, Wireless Local Area Network) and...
