Apparatus and method for identifying authority by mobile terminal multi-mode protocol stack

Abstract

The invention discloses a device for carrying out authentication by means of a multimode protocol stack of a mobile terminal, including at least: a mode selecting module (101) used for selecting a working mode for the mobile terminal according to a received signal, a subscriber identity module SIM card-managing module (103) used for managing SIM card drivers of different types and identifying inserted SIM cards of different types, an interface managing module (104), which is used for reading and storing user information through the SIM card managing module (103) and the SIM cards of different types, and receiving authentication request information of a network side through different protocol stacks, as well as sending out an authentication responding message to different network sides through corresponded protocol stacks, and an authentication execution module (102) used for acquiring user information through the interface managing module (104), receiving authentication request information sent out by the network side, and carrying out an authentication operation to the information by means of a corresponded authentication algorithm to generate authentication responding information; and then the generated information is sent out to the interface managing module (104). The invention provides an authentication function after a completion of a UMTS mode, a WiMAX mode and a dual-mode of UMTS / WiMAX in one mobile terminal.

Description

technical field [0001] The invention relates to authentication technology in the field of mobile communication, and specifically refers to a device and method for authentication by using a multi-mode protocol stack of a mobile terminal. Background technique [0002] In recent years, the number of mobile users has grown rapidly. While using voice services, users have also put forward higher requirements for mobile data services. High-speed wireless access is imperative. The integration of heterogeneous networks has become a clear direction for future network development. , where the integration of the WiMAX network and the third generation mobile communication network (3G, 3rd Generation Mobile Telecommunication Network) is a representative, but each of the WiMAX network and the 3G network has its own authentication mechanism. [0003] The authentication mechanism in the WiMAX security architecture supports bidirectional device authentication between the mobile terminal and t...

Problems solved by technology

[0008] For the joint networking of 3G network and WiMAX network, whether it is core network integration or future access network integration, the WiMAX / 3G dual-mode terminal protocol stack needs to solve the authentication problem of the two access networks; In the early stage of development, the mentioned authentication schemes are all concentrated on the network side, and no one has proposed a patent for the relevant technical scheme for the solution of the mobile terminal protocol stack
