Problems solved by technology

[0002] Since traditional devices generally use one SIM card for one machine, for data transmission terminals with dual cards and single standby, in fact, only one number or at most two numbers can be used for services. When it is necessary to change operators and different tariff cards , the user also needs to manually switch the SIM card. Even if it is a dual-card dual-standby device, it can only artificially select the optimal communication card number for communication every time it communicates.

Embodiment Construction

[0029] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0030] Such as figure 1 As shown, this embodiment describes a method for implementing a virtual SIM / USIM card, including the following steps:

[0031] S1. The system detects whether a card is inserted into the card slot of the user terminal, and judges whether the inserted card is a physical SIM / USIM card or a virtual SIM / USIM card;

[0032] S2. If the detected inserted card is a physical SIM / USIM card, start the authentication operation of the physical card;

[0033] S3. If the detected inserted card is a virtual SIM / USIM card, then start the authentication operation of the virtual card to verify the validity of the multiple virtual SIM / USIM card numbers stored in the network access information storage module;

[0034] S4. After the virt...

Abstract

The invention discloses an implementation method for a virtual SIM / USIM card, and the method comprises the following steps: S1, detecting whether there is a card in a card slot of a user terminal or not through a system, and judging whether the card is a real SIM / USIM card or a virtual SIM / USIM card; S2, starting the authentication operation of a rear card if the detected card is the real SIM / USIM card; S3, starting the authentication operation of the virtual card if the detected card is the virtual SIM / USIM card, and verifying the validity of a plurality of virtual SIM / USIM card numbers stored in a network access information storage module; S4, selecting the optimal card number from the plurality of virtual SIM / USIM card numbers for communication through an optimal card number distribution module after the validity verification of the virtual SIM / USIM card. The method provided by the invention can achieve a purpose that the virtual SIM / USIM card with the plurality of virtual SIM / USIM card numbers is used for communication at the user terminal, can achieve a multiple-number service function through one cellphone, automatically selects the optimal card number from the plurality of virtual SIM / USIM card numbers according to a communication mode, and completes communication in an optimal mode.

Description

technical field [0001] The invention relates to the field of virtual SIM cards, in particular to a method for realizing a virtual SIM / USIM card. Background technique [0002] Since traditional devices generally use one SIM card for one machine, for data transmission terminals with dual cards and single standby, in fact, only one number or at most two numbers can be used for services. When it is necessary to change operators and different tariff cards , It also requires the user to manually switch the SIM card. Even if it is a dual-card dual-standby device, it can only artificially select the optimal communication card number for communication every time it communicates. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for implementing a virtual SIM / USIM card. Communication can realize the multi-number service function of one machine, and automatically select the optimal card numbe...
