Example Embodiment

[0062] The present invention will be described in detail below with reference to the drawings and embodiments.

[0063] figure 2 It is a flowchart of the CSG database triggering the network to update the CSG list to the terminal in the embodiment of the present invention.

[0064] The CSG database is a database that saves the relevant data and permissions of the CSG user group in the network. It is set in the core network element that manages the femtocell. It can be a separate network element or set in the OMC (Operating & Maintenance Center). Center) or EPC network elements (such as home base station gateway, MME, HSS). The CSG database is managed by the operator, and the Owner of the CSG users modifies the relevant data in the CSG database under the supervision and permission of the operator.

[0065] Such as figure 2 As shown, the method for the CSG database to trigger the update of the CSG list includes the following steps:

[0066] 201: The CSG database detects that the C...

Abstract

This invention discloses a method for updating the internal user group list of a terminal, which includes the following steps: the connection management status of a registered terminal is checked when an MME needs to update a CSG list of the registered terminal; when the check result indicates that the connection management of the terminal is in a connection status, the MME notifies the terminal to update the CSG list by sending a GUTI reassigning instruction message or a CSG list management message to the terminal; the terminal completes the update of the CSG list on the basis of the CSG list update parameters contained in the GUTI reassigning instruction message or the CSG list management message. The method of the invention has no influence on various current workflows and needs not to consider the location relationship of a base station and a household base station; the CSG list of user terminal can be updated in time by the network, the user terminal without relevant authority can be prevented from being accessed to the household base station which the user terminal is required to visit and the user terminal possessing the authority can be accessed to the household base station in time.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for updating a terminal's internal subscriber group (Closed Subscriber Group, CSG for short) list. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and reduce the operating costs of operators, 3GPP (3rd Generation Partnership Project, The third generation partnership project) standard working group is working on the research of EPS (Evolved Packet System, evolution system). Such as figure 1 As shown, the EPS is divided into two parts: E-UTRAN (Evolved Universal Terrestrial Radio Access Network, evolved wireless network) and EPC (Evolved Packet Core, evolved network). [0003] EPC includes: HSS (Home Subscriber Server, home subscriber data server), MME ...
