Embodiment Construction

[0013] Details are presented here for purposes of illustrative discussion of embodiments of the invention, by way of example. Instructions and attached Figure 1 It is intended to acquaint those skilled in the art how the present invention may actually be practiced.

[0014] In addition, in order to avoid obscuring the present invention, the fact that details about implementing such a block diagram largely depend on the platform on which the present invention is implemented is also taken into account, that is, the details should be within the ability of those skilled in the art, and can be described as a block diagram Form expresses arrangement. While specific details (eg, circuits, flowcharts) are set forth to describe example embodiments of the invention, it will be apparent to those skilled in the art that the invention can be practiced without these specific details. Finally, it is apparent that any combination of hardwired circuitry and software instructions can be used...

Abstract

A method and system for authentication of a mobile device that includes a mobile device and a network element in a communications network. The network element may be a call state control function. If the network element detects an incorrect event related to a mobile device, the network element shortens a registration validity time for the mobile device and sends the mobile device a notification to re-authenticate. The incorrect event can be, for example, an incorrect authentication response, an incorrect action by the mobile device, a session over a time maximum, traffic generated being over a maximum, or credit run out. The mobile device is de-registered if the mobile device fails to re-authenticate within the shortened registration validity time, and re-registered if the mobile device re-authenticates within the shortened registration validity time. The registration validity time for the mobile device is extended after re-registration.

Description

technical field [0001] The present invention relates to communication systems, in particular but not exclusively to communication systems in which registration and / or authentication with the system is provided. Background technique [0002] An exemplary IP communication network has been introduced in the fifth edition of the 3rd Generation Partnership Project (3GPP) specification. Different technical specifications (available on the 3gpp.org website) address various aspects of the network. [0003] The 3GPP Technical Specification 3G TS 24.229: "SIPMultimedia Call COntrol Protocol based on SIP and SDP" (TS 24.3.229v2.0.0(2002-02)), which is included here by reference, introduces , users, etc.) and different network elements, such as serving call state control function (S-CSCF), proxy call state control function (P-CSCF), interrogating call state control function (I-CSCF), call control protocol between . Section 5.4.1 of TS 24.299 introduces UE registration and authenticat...
