Acquisition method of authentication policy, authentication method, authentication device, communication device, base station and terminal

Abstract

The authorizing method includes steps: down sending authorizing strategy on network side in use for directing the device to carry out authorizing operation to the terminal; the terminal receives the said authorizing strategy; combining the authorizing strategy setup in advance with the down sent authorizing strategy on network side carries out authorizing operation to the terminal. The communication device includes base station, and authorizing strategy process unit (ASPU). ASPU is in use for adding the direction of authorizing strategy into message of finding and selecting network. The base station is in use for down sending the said message with carried authorizing strategy to the terminal. The invention improves authorizing flow, and raises authorizing success ratio.

Description

technical field [0001] The invention relates to the field of authentication, in particular to a method for acquiring an authentication strategy, an authentication method, an authenticator, a communication device, a base station and a terminal. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access) is a wireless metropolitan area network technology based on the IEEE 802.16 standard. The WiMAX network using this technology is mainly composed of three parts, namely the client (MSS / SS), the access service network (ASN) and the connection service network (CSN). ASN includes a base station (BS) and an access service network gateway (ASN GW). The ASN belongs to a Network Access Point (NAP, Network Access Point), and the CSN belongs to a Network Service Provider (NSP, Network service provider). When we talk about the authentication strategy of NSP in this article, it can be understood as the authentica...

AI Technical Summary

Problems solved by technology

When the terminal moves to a remote network, the authentication policy on the current serving ASN may be inconsistent with the authentication policy on the original CSN, and the current ASN cannot inform the MS of the correct and complete authentication policy required by the network side, nor can it be used in the subsequent During the authentication and authentication process, control the MS to execute the correct authentication and authentication method

[0019] Similarly, when the MS performs re-authentication, the above-mentioned problems may cause authentication failure
