Problems solved by technology

[0008] It can be seen that this method ignores the restrictions of the CSG list. For MTC terminals or other terminals, malicious terminals will continue to try to access, which will have a greater impact on the wireless access of the home base station. The terminal will not try to access the network, so this method still cannot make the terminal reasonably access network resources and effectively use network resources

Embodiment 1

[0049] Embodiment 1 of the present invention takes LTE (Long Term Evolution, long-term evolution) system architecture as an example, and proposes a CSG list update process, which may include the following steps:

[0050] In step 201, the MTC terminal receives cell information sent by a CSG cell, and obtains a CSG list according to the received cell information.

[0051] Specifically, the MTC terminal may receive information sent by the CSG cell through a cell measurement or detection process, and may generate a CSG list that can be accessed according to the received CSG cell information. The MTC terminal may measure the network access nodes around the MTC terminal in a preset manner, for example, at a certain period in an idle state, or may trigger the measurement by setting a specific event. The CSG list may include relevant information of one or more cells that can be detected by the MTC terminal. In this step, the specific implementation of the cell information received by...

Embodiment 2

[0064] Embodiment 2 of the present invention proposes an access control method, such as image 3 As shown, the flow of the method may include the following steps:

[0065] In step 301, the MTC terminal receives system information sent by the base station, and the system information carries access permission indication information.

[0066] Specifically, the base station may be a home base station, or other communication base stations with CSG management functions, and the MTC terminal access indication information (such as MTC Allowed) may be set in the system information of the base station, and the MTC terminal access indication information is used for Indicates that the MTC terminal is allowed to access the home base station. The MTC terminal access indication information can be 1-bit identification information, and its value can be 0 or 1. When it is 0, it means that the MTC terminal is allowed to access, when it is 1, it means that the MTC terminal is not allowed to acce...

Abstract

The invention discloses a method and equipment for controlling updating and access of closed subscriber group (CSG) cell information. The method comprises the following steps that: a terminal receives cell information transmitted by a CSG cell, acquires accessible CSG cell information according to the received cell information, and transmits the accessible CSG cell information to a network side; and the terminal receives CSG cell information which is returned by the network side and allowed to access or confirmation information of the accessible CSG cell information, and the CSG cell information of the terminal is updated according to the CSG cell information which is allowed to access or the confirmation information. The terminal receives the cell information transmitted by the CSG cell, acquires the CSG cell information and transmits the CSG cell information to the network side, and the CSG cell information transmitted by the terminal is determined and informed to the terminal for updating through equipment on the network side, so that the terminal can be ensured to access network resources reasonably, and the utilization efficiency of the network resources is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for CSG cell information update and access control. Background technique [0002] CSG (Closed Subscriber Group, Closed Subscriber Group) is a small network that covers a limited area and serves specific users. It is called a closed subscriber group. Only users belonging to this group can access this network. Before accessing the network, the terminal first reads the identity of the CSG cell from the CSG cell, and matches the identity of the read CSG cell with the identity of the CSG cell in the CSG list stored by the terminal itself, so as to determine whether it can access the CSG district. [0003] The prior art provides a method for updating the CSG list initiated by the network side. In this method, when the MME (Mobile Management Entity, mobile management entity) and the terminal's allowed access list (Allowed CSG List, hereinafter referred to as the...
