Embodiment 1

[0021] Embodiment 1. A dual IMSI automatic switching method for global roaming. Combine below Figure 1-Figure 4 The method provided in this embodiment will be described in detail.

[0022] see figure 1 and figure 2 ,in, figure 1 Among them, S101. When the mobile terminal is turned on stably, detect the network status of the current IMSI of the SIM card in the mobile terminal at the current location and obtain the current location information of the mobile terminal.

[0023] Specifically, when a mobile terminal user travels from one region to another, for example, after arriving in the United States from China, the mobile terminal enters a booting process. see image 3 , the specific process for the mobile terminal to enter the boot process is that the mobile terminal sends a Terminal Profile command to enable the mobile terminal to enter the boot process. At this time, the SIM card creates a menu item and executes the Set up menu command, and sets the Poll Interval poll...

Embodiment 2

[0034] Embodiment 2. A dual IMSI automatic switching system for global roaming. Combine below Figure 5 The system provided in this embodiment will be described in detail.

[0035] Figure 5 Among them, the system provided by this embodiment includes a network status detection module 501 , a network status determination module 502 , a switching times setting module 503 , a switching module 504 and a restarting module 505 .

[0036] Wherein, the network state detection module 501 is mainly used for detecting the network state of the current IMSI of the SIM card in the mobile terminal at the current location and obtaining the current location information of the mobile terminal when the mobile terminal is powered on stably. Specifically, when a mobile terminal user travels from one region to another, for example, after arriving in the United States from China, the mobile terminal enters a booting process. The specific process for the mobile terminal to enter the boot process i...

Abstract

The invention discloses a dual-IMSI (International Mobile Subscriber Identity) automatic switching method and system for realizing global roaming. The method comprises the following step: after a mobile phone terminal is started and stable, detecting the network state of a current IMSI, in a current position, of an SIM (subscriber identity module) card in the mobile phone terminal and obtaining current position information of the mobile phone terminal; when the detected network state of the current IMSI, in the current position, of the SIM card is changed and needs to be switched, switching the current IMSI of the SIM card to another IMSI for logging in a network having a roaming communication protocol with the IMSI; restarting the mobile phone terminal for bringing the IMSI switching to operation. According to the method provided by the invention, the IMSI switching can be efficiently, quickly and accurately carried out according to the network state of the current IMSI of the SIM card and the position of the mobile phone terminal under the circumstance that the SIM card is not changed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a dual IMSI automatic switching method and system for realizing global roaming. Background technique [0002] When a mobile terminal user travels from one region to another, such as from one country to another, the current IMSI (International Mobile Subscriber Identification Number) of the SIM card in the mobile terminal may fail to log in in another country. At this time, the mobile phone terminal cannot realize the communication function. [0003] At present, the main way to solve this problem is to replace the SIM (Subscriber Identity Module, customer identification module) card in the mobile terminal to access the mobile network of foreign operators. Adopt the mode of changing SIM card, mobile phone terminal user needs to apply for card again, change card and change number, the process is complicated, and needs to spend the extra communication fee of user. Con...
