Patent number: 9253638Abstract: Provided are a single-card multi-mode multi-operator authentication method and device. An MAML in an AP receives an authentication request from a user, and authenticates hybrid networks found by a UE. Under the condition of determining that the authentication on each network in the hybrid networks is passed, the MAML receives terminal position information sent by the UE, and determines whether the terminal position information is the same as operator area information registered by the UE in advance, if so, the MAML acquires signal strength of each network and determines whether the signal strength of each network falls within a signal strength range covered by a base station under the network, if so, determines that all the networks in the hybrid networks are authenticated successfully, otherwise, determines that the authentication fails. The security in using an SIM card by a valid user and secure network service are ensured.Type: GrantFiled: June 7, 2012Date of Patent: February 2, 2016Assignee: ZTE CORPORATIONInventors: Meng Xia, Jin Liu
