[0072] see image 3 , providing a first embodiment of a method for operator network switching according to the present invention, in this embodiment, the method includes the steps of:

[0073] S101. Obtain the signal strength of the communication terminal entity subscriber identity card corresponding to the first operator's network.

[0074] In the embodiment of the present invention, the communication terminal should include at least one physical SIM card and one virtual SIM card.

[0075] In one embodiment, obtaining the signal strength of the current communication terminal entity subscriber identity card corresponding to the first operator's network includes but is not limited to the following two methods. Method 1: Obtain the number of signal grids displayed on the upper interface of the communication terminal, such as the signal grid The number is two grids; Method 2: Obtain the receiving level of the communication terminal, for example, the receiving level is -90dBm. H...

Abstract

The invention discloses an operator network switching method and a communication terminal. The communication terminal comprises an entity subscriber identity module (SIM) card and a soft SIM card. The method comprises the following steps: acquiring the signal strength of a first operator network corresponding to the entity SIM card of the communication terminal; when the signal strength of the first operator network corresponding to the entity SIM card meets preset conditions, activating the soft SIM card; and making the soft SIM card connected to a server, getting card resources, and connecting the terminal to a corresponding second operator network, wherein the server owns the entity card resources of all operators. The technical scheme of the invention has the beneficial effect that in an area with poor coverage of a certain operator network, in order to avoid the situation in which a terminal misses an incoming call or transmits/receives information in a delayed manner due to the absence of signal service, the communication terminal can activate the soft SIM card thereof to reside in other operator networks, so the terminal always has signals, and convenience is brought to users.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a method for switching an operator's network and a communication terminal. Background technique [0002] With the successive commercialization of various mobile network protocols, covering multiple network signals in the same area has become a common phenomenon. Subscriber Identity Module (SIM) card, also known as subscriber identity card, SIM card stores communication terminal user information, encrypted keys and other content on the chip, which can be used by the operator network to identify user identities. And encrypt the voice information when the user calls. Users can select a SIM card corresponding to the operator's network according to their own needs, and cooperate with a communication terminal (for example, a mobile phone) to use the mobile network for voice or data services. In the usage scenario of traditional SIM cards, people usually have to...
