One-phone multi-number user terminal based on virtual card

Abstract

The invention discloses a one-phone multi-number user terminal based on a virtual card. A one-phone multi-number function is realized at the user terminal through integrating a virtual card module or inserting the virtual card module with a card slot. The virtual card module at least comprises an optimal card number distribution module and an access network information storage module. Connection interaction with the virtual card module is carried out at the user terminal through an I / O interface; connection interaction with the upper system of the virtual card module is carried out at the user terminal through a wireless interface; the upper system comprises a virtual card operation and maintenance server. According to the invention, the virtual card module with a plurality of virtual SIM / USIM card numbers is built in the user terminal; one-phone multi-number service function is realized; and an optimal card number is automatically selected from a plurality of virtual SIM / USIM card numbers according to a communication mode so as to finish communication in optimal mode.

Description

technical field [0001] The invention relates to the field of virtual SIM cards, in particular to a virtual card-based one-machine multi-number user terminal. 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 virtual card-based one-machine multi-number user terminal, the user terminal has a built-in virtual card module with multiple virtual SIM / USIM card numbers, whi...
