Problems solved by technology

Although a mobile station accessing a cellular system using an unlicensed radio access network can be authenticated in the same manner as for a legacy access network, defective mobile stations impose a heavy burden on the access and core networks. operational burden, such as when they generate location updates or other information in the loop

Embodiment Construction

[0019] Figure 1 schematically depicts parts of a conventional GSM network. The network is basically divided into a core network part 20 and an access part also called Base Station Subsystem BSS 10 . Components of the core network 20 illustrated in the figure include a mobile switching center or MSC 202 , an associated home location register HLR 201 and a visitor location register VLR 204 . The functions and structures of these conventional GSM architecture components are well known to those skilled in the art and thus will not be described in further detail herein. Although not shown in the figure, those skilled in the art will understand that the core network part may include other mobile and fixed networks (such as ISDN and PSTN networks), packet and circuit switched packet data networks (such as through one or more gateways) Node's Intranet, Extranet and Internet) access. Also depicted is the Equipment Identity Register EIR 205, which is a database storing the identity of...

Abstract

An unlicensed-radio access network includes an access controller (303) adapted to communicate with the core network portion of a public mobile communication network (20) and connected to a broadband packet-switched network (302). The access controller receives messages from mobile stations via the broadband packet-switched network. The access controller comprises a screening module (3031-3034) for monitoring information received from a mobile station and a connection controller (3035) coupled to the screening module for controlling the connection between the mobile station and the access controller. The screening module is adapted to determine whether a mobile station is permitted to connect to the access controller, and the connection controller is adapted to terminate a connection with the mobile station if the screening module determines that the mobile station is not permitted to connect to the access controller.

Description

technical field [0001] The invention relates to the authentication of a mobile station for access to a cellular communication system via an unlicensed radio access network. Background technique [0002] In conventional cellular networks like GSM, for example, the identity of the mobile station is checked and its operation and rights to access the network are used by various components in the core network part, such as Home Location Register (HLR), Device Identity Register ( EIR) and Authentication Center (AUC) to be authenticated. [0003] A conventional cellular network is accessible via an unlicensed radio including an access network controller for interfacing with the core network portion of a conventional cellular system and for controlling a plurality of access points suitable for communicating with mobile stations over an unlicensed radio interface The provision of the access network is to be extended. The unlicensed radio interface may use any radio technology that ...
