Information acquisition method and core management network element

Abstract

The embodiment of the invention relates to an information acquisition method and a core management network element, and the method comprises the steps of receiving an access request message carrying a mark of a closed subscriber group CSG; and determining whether a target cell requesting access is a CSG cell or not according to the mark of the CSG, if so, acquiring CSG subscription information. The embodiment can determine the target cell requesting the access is the CSG cell or not according to the mark of the CSG carried in the access request message, if so, the embodiment can acquire the CSG subscription information. The core management network element can acquire the CSG subscription information in a CSG management server when the target cell is the CSG cell, thereby reducing signaling load between the core management network element and the CSG management server and improving the information processing efficiency of the core management network element and the CSG management server.

Description

technical field [0001] The invention relates to the communication field, in particular to an information acquisition method and a core management network element. Background technique [0002] At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, hereinafter referred to as: 3GPP) and the non-3rd Generation Partnership Project (hereinafter referred to as: non-3GPP) standard organizations are studying a new interface Access mode: home access (Home), user equipment (User Equipment, hereinafter referred to as: UE) through the home wireless access point, using licensed spectrum such as: global UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, hereinafter referred to as: UTRAN), Evolved-UTRAN (hereinafter referred to as: E-UTRAN), Code Division Multiple Access (Code Division Multiple Access, hereinafter referred to as: CDMA), and Worldwide Interoperability for Microwave Access (hereinafter referred to as : Wimax), wire...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that the existing technology has at least the following defects: when the existing UE accesses the wireless network, the core management network element cannot determine under what circumstances it is necessary to obtain the UE’s corresponding CSG subscription information, Whether the CSG cell accesses the wireless network or accesses the wireless network from the CSG cell, the core management network element must obtain the CSG subscription information corresponding to the UE from the CSG management server, which greatly increases the distance between the core management network element and the CSG management server. Signaling load, which affects the processing load of core management network elements and CSG management servers
