Authentication parameter updating method, apparatus thereof and system thereof

Abstract

The invention, which relates to the communication technology field, provides an authentication parameter updating method, an apparatus thereof and a system thereof. The invention relates to the parameter updating method, which is used for a machine-and-card integration terminal. The method comprises the following steps that: a session between a terminal and gateway equipment is established; a receiving terminal of the gateway equipment initiates a first-time PPP process; during the process, when an authentication parameter needs to be initialized or updated, the gateway equipment sends a CHAP authentication failure message to the terminal by interaction between the gateway equipment and AAA equipment; and the terminal generates a terminal side CHAP SS; the receiving terminal of the gateway equipment initiates a second-time PPP process; during the process, the AAA equipment generates an AAA side CHAP SS and information in a database of the AAA equipment is updated; meanwhile, the terminal utilizes the terminal side CHAP SS to update a storage area of the terminal; and the receiving terminal of the gateway equipment initiates a third-time PPP process; during the process, the terminal utilized the terminal side CHAP SS to respond a CHAP challenge initiated by the gateway equipment; and the AAA equipment utilizes the AAA side CHAP SS to carry out authentication on the terminal so as to complete initialization or updating of the authentication parameter. According to the invention, problems on initialization and updating of an authentication parameter of a machine-and-card integration terminal can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication parameter updating method, device and system. Background technique [0002] For code division multiple access (CDMA) machine-card integrated terminals, since the terminal does not have a user identification module (UIM) card, user data and network data are stored on the terminal. Relevant user and network parameters are written into the terminal memory so that the terminal can access the network smoothly. A commonly used method at present is to write parameters manually, that is, write the relevant parameters of the terminal into the relevant storage area of ​​the terminal through some special tools, and at the same time update the data stored in each network element in the network correspondingly, including the home location register (HLR ), authentication / authorization / accounting (AAA) equipment, access network AAA (AN-AAA) equipment, etc. Ano...
