Embodiments of the invention

For a better understanding of the embodiments of the present invention, a brief description of the process of registering a mobile network mobile terminal to a mobile network is provided below.

Since the mobile network is composed of a myriad of cells, the network operator will set different cells in different regions according to various factors such as customer distribution, construction cost and planning to meet customer needs; therefore, the same network operator is in different regions of the same country, or There may be differences in network configurations between urban and suburban areas in the same city, which may result in large differences in network quality between different network operators in the same region. It is also difficult for a network operator to have better network quality in all regions than in other regions. Network operators; for example, in China's key urban areas, China Unicom's Wideband Code Division Multiple Access (WCDMA) network quality and network speed are significantly better than China Mobile's Time Division Synchronous Code Division Multiple Access (Time Division) -Synchronous Code Division Multiple Access (TD-SCDMA) network; in China's suburbs, China Mobile's TD-SCDMA network quality and network speed are significantly better than China Unicom's Global System for Mobile Communication (GSM) network.

In order to enable users to obtain better service and user experience, the optimal mobile network can be selected in real time according to the location of the user; the measurement, reselection and handover schemes between the mobile networks specified by the 3GPP protocol and the 3GPP2 protocol are all in the same network operator. Between networks or equivalent networks; mobile terminals are in progress When registering the network, you need to select a specific mobile country code (MCC) based on the information of the Home Public Land Mobile Network (HPLMN) and the Equivalent Home PLMN (EHPLMN) information in the SIM card. And Mobile Network Code (MNC); during the use of the mobile terminal, the target cell measured by the mobile terminal is pre-configured in the presence list of the current cell by the network side, and broadcasted to the mobile in the form of a system message. Terminal; the related art does not support network switching without equivalent relationship, nor does it support measurement and handover between networks of different network operators; and 3GPP protocol stipulates that when the mobile terminal is in the connected state, it cannot initiate network search, only In the idle state and in international roaming, the mobile terminal can periodically search for HPLMN and EHPLMN.

The basic processing flow of the method for switching a mobile network provided by the embodiment of the present invention, as shown in FIG. 1 , includes the following steps:
