Problems solved by technology

Usually, users on this network can roam to a partner network by signing a roaming agreement, but this method has a disadvantage, that is, it involves the settlement of inter-network fees between the two operators, which is very troublesome and prone to disputes

Embodiment Construction

[0020] In this invention, for the convenience of description, we refer to the operator's own IMSI as Home IMSI, the partner IMSI as Partner IMSI, the operator's own network as Home network, and the partner's network as Partner network. .

[0021] The technical solution of the present invention is to provide an IMSI switching method. When the Home network exists, the mobile terminal registers with the Home network with the Home IMSI. At this time, the mobile terminal is equivalent to an ordinary user of the Home network. When the Home network does not exist, it uses the Partner IMSI to register with the Partner network. At this time, the mobile terminal is equivalent to the Partner network. an ordinary user.

[0022] In the technical scheme of the present invention, a SIM / USIM card contains multiple sets of user data (IMSI, OPLMN, LOCI, FPLMN, short message center number, etc.), and by default, the mobile terminal reads from the SIM / USIM card is the Home IMSI, and the user da...

Abstract

The invention provides a mobile terminal and a network switching method thereof. The mobile terminal reads an IMSI and the user data corresponding to the IMSI from the SIM / USIM card; the mobile terminal tries to use the IMSI to register with the network, if the registration fails, the SIM / USIM card changes the user data to the user data of another network, and The mobile terminal is notified to re-read the user data, and the mobile terminal registers with the network using the IMSI corresponding to the re-read user data. Compared with the prior art, the technical scheme of the present invention not only realizes the roaming of the mobile terminal between networks, but also simplifies the process of settlement of roaming charges between operators, thereby improving user experience.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a mobile terminal and a method for switching networks thereof. Background technique [0002] Generally, the SIM / USIM card will contain a set of IMSI (International Mobile Subscriber Identification Number, the method of International Mobile Subscriber Identification Number), OPLMN, LOCI, FPLMN, short message center number, etc. After the mobile terminal is powered on, it will start from Read these data in the SIM / USIM card, and then register the corresponding network. [0003] At present, with the rapid development of the mobile communication market, new operators continue to appear, but the initial investment required for the mobile communication system is very large. It is difficult to build a complete network in the early stage. In order to solve this problem, some emerging operators will find another operator as a partner in the early stage. In places ...
