Problems solved by technology
[0004] However, because in some countries or regions, there is no contract with the operators of multi-mode cards, these countries or regions do not support the roaming of multi-mode cards (for example, CDMA multi-mode cards) of these networks, and users are in these countries or regions It is impossible to log in and search for the other networks mentioned above, which makes the application of multi-mode cards (for example, CDMA multi-mode cards) of these networks limited, and the switching efficiency between different networks is low.

Embodiment Construction
[0049] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0050] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the network switching method for the multi-mode card terminal of the present invention.
[0051] This embodiment proposes a network switching method for a multi-mode card terminal, including:
[0052] Step S10, obtaining the mobile country code and / or mobile network code of the current network searched by the terminal;
[0053] When the user triggers the acquisition instruction of the mobile country code and / or mobile network code of the current network of the terminal, the terminal searches for the network at the current location, and obtains the mobile country code and / or m...

A network switching method and apparatus for a multi-mode card terminal. The mobile country code and / or mobile network code of a network for which a terminal searches is obtained, and when the obtained mobile country code and / or mobile network code matches the mobile country code and / or mobile network code in the pre-stored IMSI information of a country unsubscribed to the multi-mode card, and the currently registered IMSI of the multi-mode card is not the IMSI of the unsubscribed country, the current IMSI of the multi-mode card is switched to the IMSI of the unsubscribed country, or when the obtained mobile country code and / or mobile network code matches the mobile country code and / or mobile network code in the pre-stored IMSI information of a country subscribed to the multi-mode card, and the currently registered IMSI of the multi-mode card is not the IMSI of the subscribed country, the current IMSI of the multi-mode card is switched to the IMSI of the subscribed country, so that the terminal switches the communication network to the searched current network on the basis of the switched IMSI; therefore, the range of application of the multi-mode card is widened on the premise that the network switching efficiency of the multi-mode card is guaranteed.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a network switching method and device for a multi-mode card terminal. Background technique [0002] Among the existing mobile communication terminals, due to the gradual expansion of the scope of activities of users, the opportunities to go abroad are gradually increasing, and the specific network modes used by countries are very different, single-mode card terminals have become increasingly unable to meet the needs of a large number of users to roam abroad , so terminals with multi-mode card functions have gradually appeared to meet the needs of users for roaming abroad. [0003] Since some networks, such as CDMA (Code Division Multiple Access, Code Multiple Access) networks, are rarely used in roaming communication, in countries or regions without these networks (such as CDMA networks), multi-mode cards ( For example, CDMA multi-mode card) can use other networks such as...
