Title: SINGLE-CARD MULTI-MODE MULTI-OPERATOR AUTHENTICATION METHOD AND DEVICE
Abstract:
Disclosed are a single-card multi-mode multi-operator authentication method and device. The method comprises: an MAML in an AP receiving an authentication request from a user, and authenticating a hybrid network found by a UE; under the condition of determining that the authentication of each network in the hybrid network is passed, receiving terminal position information sent by the UE, and determining whether the terminal position information is the same as operator area information pre-registered by the UE; and when the terminal position information is the same as the operator area information pre-registered by the UE, the MAML acquiring signal strength of each network and determining whether the signal strength of each network falls within a signal strength range covered by a base station under the network; if a determination result is yes, determining that all the networks in the hybrid network are authenticated successfully, and otherwise, determining that the authentication fails. By means of the present invention, the security in using an SIM card by a valid user and secure network service are ensured, and the effect of favorable network operation of operators is ensured.
