System and method for implementing authentication on user of home base station

Abstract

The invention provides a system and a method for implementing authentication on a user of a home base station. The method comprises the following steps that: in the process of requesting for access to the home base station in a closed access mode or a mixed access mode by a terminal, an access gateway sends user identification information, a home base station identifier and a home base station mode to an authentication and authorization server, or to a user server of a closed user group CSG through the authentication and authorization server; when the home base station is in the closed access mode, the authentication and authorization server or the CSG user server judges whether to allow the user to access the home base station or not and returns a judgment result to the home base station through the access gateway; and when the home base station is in the mixed access mode, the authentication and authorization server or the user server of the closed user group CSG determines user type information and returns the type information to the home base station through the access gateway. The system and the method can avoid transferring a real user identifier frequently at a hollow port, and reduce the burden of the home base station and the potential safety hazard of the home base station.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a system and method for implementing authentication on home base station users. Background technique [0002] Home base stations are small, low-power base stations that are deployed in indoor places such as homes and offices. Insufficient coverage of cellular wireless communication systems. The advantages of femto base stations are affordable, convenient, low power output, plug and play, etc. The home base station system has already been implemented in the 3rd Generation Partnership Project (3GPP for short), the 3rd Generation Partnership Project 2 (3GPP2 for short) and the Worldwide Interoperability for Microwave Access (Worldwide Interoperability for Microwave Access, referred to as WiMAX) three major standards for research, the network architecture adopted by the femto base station system in each standard organization is basically the same, this article uses WiMAX...

AI Technical Summary

Problems solved by technology

[0019] It can be seen from the above process that the home base station checks whether the user belongs to the CSG list according to the user ID carried by the terminal (step 205). For example, EAP (Extensible Authentication Protocol, Extensible Authentication Protocol) encapsulation, at this time, the femto base station needs to analyze the authentication encapsulation protocol, which increases the operating burden of the base station node and reduces the efficiency; when the terminal encrypts and transmits the real identity, the femto base station is even more helpless Parse and obtain the user ID information; even if the terminal transmits the user ID in plain text without encapsulating the authentication message, the user ID has not been verified by the authentication and authorization server, so the correctness of the user ID cannot be guaranteed, and frequently used on the air interface Clear text transmission of the user's real identity is easy to be stolen by others, and there is a security risk in the wireless communication system
