Description

The present invention relates to the field of communications, and in particular to a home base station access control method, apparatus, and system. BACKGROUND OF THE INVENTION A home base station is a small, low-power base station that is deployed in indoor places such as homes and offices. The main role of the home base station is to provide users with higher service rates and lower the cost of using high-rate services, while at the same time making up for the deficiencies of existing distributed cellular wireless communication systems. The advantages of home base stations are affordable, convenient, low power output, plug and play, and more. As shown in FIG. 1 , in a Long-Term Evolution (LTE) system, a terminal is connected to a core network through a Home eNodeB Access Network (HeNB AN), where HeNB AN is The Home eNodeB (HeNB for short) and the Home eNodeB Gateway (HeNB GW for short) are combined. The main functions performed by the HeNB GW are: processing registration and access control of the home base station, verifying the home base station, and exchanging data of the core network and the home base station. In addition, the Home eNodeB Manage System (HeMS) performs operation and maintenance management on the home base station, and configures and controls the home base station according to the requirements of the operator. The HeNB implements configuration management functions, including verification of location information. The parameter configuration of the HeNB is mainly related to the parameter configuration of the Mobility Management Entity (MME) level, the parameter configuration of the radio access network (Radio Access Network, RAN for short), and the radio frequency (Radio Frequency, Parameter configuration for RF). In the HeNB system under the LTE system, the HeNB may directly connect to the MME without passing through the HeNB GW. With the development of technology, the home base station introduces the concept of Close Subscriber Group (CSG), which refers to a group of subscribers, each of which allows access to one or more specific cells. There are three access modes in the HeNB: closed access mode (allows access if the user's CSG ID is the same as the HeNB's own CSG ID), open access mode (any user is allowed to access), hybrid (Hybrid) Access mode (no matter whether the user is a subscriber of the CSG, access is allowed, and the subscriber of the CSG is preferentially accessed). At the same time, the user's mobility management also introduces the concept of the current user CSG information. The user CSG information includes the CSG ID of the current user accessing the cell, and the access mode of the user currently accessing the cell. And the CSG identity of the user in the currently accessed cell (CSG membership indication) „ When the user performs the process of attaching, tracking area update (TAU) and handover (Handover), the core network obtains the user through the Home Subscriber Server (HSS). The CSG information of the subscribed CSG is usually a CSG list that is allowed to be accessed by the user. The CSG information of the cell currently accessed by the user is obtained by the user and the access side.

In the LTE system, there are two types of handover to the terminal, namely, S1 handover and X2 handover. The S1 switch is as shown in FIG. 2, and mainly includes: Handover Required, Handover Request, Handover Request Acknowledge, Handover Command, and user plane data transmission; S1 switching It is a general handover method, which can be used in various handover scenarios. The MME participates in the handover process, and the access control in the handover process is completed by the MME. In the X2 handover process, the handover process is completed on the access network side, and the MME does not participate in the handover process. The X2 handover needs to perform access control on the terminal, and the ACL required for the access control does not exist in the home base station. In the network access system, therefore, X2 switching requires a method to obtain the ACL of the terminal to complete access control to the terminal.
