Single-card multi-mode multi-operator authentication method and device

Abstract

The invention discloses a single-card multi-mode multi-operator authentication method and a single-card multi-mode multi-operator authentication device. The method comprises the followings steps of: receiving an authentication request from a user through an MAML in an AP (Access Point), and authenticating a mixing network found by UE (User Equipment); under the condition of confirming the authentication of each network in the mixing network to pass, receiving terminal position information transmitted by the UE, and judging whether the terminal position information is the same as operator area information pre-registrated by the UE or not; and when the terminal position information is the same as operator area information pre-registrated by the UE, acquiring signal strength of each network through the MAML, and judging whether the signal strength of each network is contained in a signal strength range covered by a base station under the network or not, if yes, confirming that all networks in the mixing network are authenticated successfully, otherwise, confirming to be fail. Through the method and the device, the safety in using an SIM (Subscriber Identity Module) card by a valid user and secure network service are ensured, and the effect of favorable network operation of operators is ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a single-card multi-mode multi-operator authentication method and device. Background technique [0002] With the issuance of 3G (third-generation mobile communication) licenses, the construction of domestic 3G networks has gradually begun, and the three major mobile communication operators have officially entered the 3G era. At the same time, the Long Term Evolution (LTE) network under the framework of 4G (fourth generation mobile communication) has been put on the construction agenda, and some cities have begun to build experimental networks. It is the TD-SCDMA standard, which is also a developing technical standard. While strengthening the TD network construction, the industry is also planning to launch a WIFI network to continuously promote the LTE process. In the implementation of 3G and the advancement of 4G, the Enhanced Data Rate for GSM Evolution (EDGE for short) networ...
