[0076] According to the first embodiment, when the terminal returns from UTRAN to E-UTRAN and performs location registration processing, the Mobility Management Entity (MME) 150a may receive an indication to obtain from the Serving General Packet Radio Service Support Node (SGSN) (mapped) The type of GUTI. Furthermore, the Mobility Management Entity (MME) 150a may make a request to the Serving General Packet Radio Service Support Node (SGSN) 170 for the context of the terminal 100 and may make a request to the Home Subscriber Server (HSS) for authentication information request.

[0077] Until the interworking with the IMS network is stably established, providers may mainly use Circuit Switched Fallback (CSFB) in order to support telephone calls, an important and widely used service among wireless communication services. Therefore, Circuit Switched Fallback (CSFB) techniques may be frequently used. In this case, the Mobility Management Entity (MME) 150a may make very frequent...

Abstract

An embodiment of the present invention relates to a method and an apparatus for collecting authentication information of a terminal while reducing the load of a home subscriber server (HSS). The present invention provides a method and an apparatus for transmitting a location registration message of a terminal for convenience of the mobility management node selection by a base station, a method and an apparatus for the mobility management node selection by a base station, and a method and an apparatus for collecting authentication information by the mobility management node. According to the embodiment of the present invention, it is possible to obtain authentication information of the terminal while reducing the load of the HSS.

Description

technical field [0001] The present invention relates to methods and devices for obtaining authentication information, including authentication vectors. More particularly, the present invention relates to a method and apparatus for obtaining authentication information (authentication vector) while reducing requests sent to the authentication center as much as possible to reduce overload of the authentication center. Background technique [0002] Initial wireless communication systems have been developed to provide voice services while allowing users to be mobile. In addition, wireless communication systems have gradually provided data services as well as voice services, and in recent years, have advanced to provide high-speed data services. [0003] figure 1 A typical wireless communication system is illustrated. refer to figure 1 , the wireless communication system may include the terminal 100, radio access networks (RAN) 125, 135, and 145, and a core network. [0004] ...
