Embodiment Construction

[0045] The present invention simultaneously stores multiple IMSIs and authentication information of each IMSI in the CG gateway and the terminal SIM card, and all IMSIs can also share the authentication information, and the CG gateway database also stores each IMSI and its authentication information.

[0046] C2G or G2C users can subscribe to the international IMSI of different operators at the same time, and the CG gateway realizes the problem of the lowest tariff when the user roams between different countries according to the pre-configured roaming strategy.

[0047] C2G or G2C users can subscribe to IMSIs in different countries at the same time, and the IMSIs in each country can roam in the corresponding countries and perform corresponding services; when the user roams to different countries, select the corresponding country IMSI to roam between countries.

[0048] The specific implementation manners of the present invention will be described in further detail below in conj...

Abstract

The invention discloses a mobile restriction implementation method of a mobile communication terminal and a CG gateway. The method comprises the following steps of: 1. judging whether a plurality of IMSIs (International Mobile Subscriber Identity) contain an international IMSI and a national IMIS by the CG gateway, performing step 2 if containing the international IMSI, and performing step 3 if only containing the national IMSI; 2. according to position update information, invoking a preset roaming strategy by the CG gateway, and switching a user to the international IMSI with the lowest expense; and 3. according to the national IMSI, switching the user to the IMSI with the lowest expense in the current roaming country by the CG gateway. In the invention, the roaming strategies of different types of IMSIs in different counties are allocated in the CG gateway, so that users can enjoy the IMSI with the lowest expense during roaming, thereby saving cost for the users.

Description

technical field [0001] The invention relates to the roaming field of a CG gateway in the communication field, in particular to a method for realizing movement restriction of a mobile communication terminal and a CG gateway. Background technique [0002] At present, the N.S0028 agreement organized by 3GPP2 provides a solution for the roaming service of C network users roaming to G network (referred to as C2G users) and G network users roaming to C network (referred to as G2C users). The network entity that realizes this function For the CG gateway. The CG gateway supports functions such as roaming, calls, short messages, supplementary services, and data services of C2G and G2C users. [0003] The existing CG gateway can only realize the roaming service from one C network operator to another G network operator or one G network operator to one C network operator. Regarding the existing roaming service processing method, as far as C2G users are concerned, if they want to roam ...
