Mobile phone companion, radio communication system and communication method

Abstract

The invention provides a mobile phone chaperone device and wireless communication system and communication method, wherein the mobile phone chaperone device comprises: a radio-frequency processing unit for communicating with mobile phone in the way of radio-frequency; at least one user identification module card unit for storing and processing the user identification module card information interacted with the mobile phone according to user identification module interface protocol; a control processing unit being connected with the radio-frequency processing unit and the user identification module card unit and for controlling the mobile phone communication request received by the radio-frequency processing unit to read the user identification module card information and transfering the user identification module card information interacted with the mobile phone to the mobile phone by the radio-frequency processing unit. The invention can realize multi SIM-cards application on present mobile phone and the change of the present mobile phone is little.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a mobile phone companion device, a wireless communication system and a communication method. Background technique [0002] A subscriber identity module (SIM, Subscriber Identity Model) card is also called a smart card or a subscriber identity card. It stores mobile phone user information, encrypted keys and other content on the chip, which can be used by the network to identify user identities, so as to prevent parallel machines and calls from being eavesdropped, thereby reliably ensuring normal communication of users. [0003] Usually, one SIM card is used on a mobile phone, but with the development of wireless communication technology, mobile phone users want to enjoy different wireless communication networks, or accept the services of different telecom operators on different wireless communication networks, and usua...

AI Technical Summary

Problems solved by technology

[0003] Usually, one SIM card is used on a mobile phone, but with the development of wireless communication technology, mobile phone users want to enjoy different wireless communication networks, or accept the services of different telecom operators on different wireless communication networks, and usually switch to another network or another telecom operator, it is necessary to replace the SIM card of the new network, but as a user, on the one hand, he wants to experience the ever-changing new business changes

On the other hand, most users are not willing to change their cards frequently (that means changing their mobile phone numbers), especially for high-end users, that is, communication itself is the most important function of mobile phones. Life brings inconvenience, so telecom operators and users bring new services to the new card, which has caused a lot of inconvenience that needs to be resolved urgently

[0004] At present, there are also mobile phones that realize multiple SIM cards such as one machine with multiple numbers and dual standby, but it is an improvement on the existing mobile phone technology, and the application of the added SIM card is limited, and the mobile phone models that support this function are also limited. , to be further improved
