Problems solved by technology

This method uses a virtualized SIM card and requires the operator to fully open the core user data and encryption algorithm of the SIM card, which will bring serious security risks and affect the interests of the operator. Therefore, it is often resisted by the operator and is extremely difficult. high

Embodiment Construction

[0016] The working process of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] like figure 1 As shown, the system for unlimited use of multiple SIM cards of the present invention includes at least one SIM card pool device, a SIM card control server and at least one terminal communication device, and the SIM card in the SIM card pool device is dynamically allocated through the SIM card control server. For terminal communication equipment.

[0018] Each SIM card pool device is provided with multiple card slots, and multiple SIM cards can be installed. The countries to which these SIM cards belong, network operators, tariff packages used, and applicable network standards can be different. The SIM card pool can back up the static data of these SIM cards, which are unencrypted SIM card data backed up according to the ISO7816 standard Host role.

[0019] The SIM card control server, according to the curre...

Abstract

The invention discloses a system for using multiple SIM cards limitlessly. The system includes an SIM card pool equipment, an SIM card control server and terminal communication equipment. The SIM card pool equipment is used for storing and managing different SIM cards, the terminal communication equipment reports the current state thereof to the SIM control server, and the SIM card control server allocates a corresponding SIM card in the corresponding SIM card pool equipment to each terminal communication equipment according to an allocation strategy and the state of the terminal communication equipment. The terminal communication equipment communicates with the corresponding SIM card pool equipment according to allocation of the SIM card control server, obtains corresponding SIM card data, and converts the corresponding SIM card data to virtual SIM card. When the virtual SIM card needs to generate a time-based or encrypted message, the terminal communication equipment forwards to a real SIM card, and obtains response data generated by the real SIM card in the SIM card pool equipment for use. The system for using multiple SIM cards limitlessly realizes dynamic matching of the SIM card and the terminal communication equipment, and enables the terminal communication equipment to use the corresponding SIM card at optimal time and in an optimal place, thereby achieving the purposes of expense reduction and global barrier-free use.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an implementation technology that can use different SIM cards according to situations without time and geographical restrictions. Background technique [0002] In the field of mobile terminal equipment, SIM card is a very important subscriber identity module (SubscriberIdentityModule), which mainly includes IMSI (International Mobile Subscriber Identity), KI value, encryption algorithm and operator information, etc. The SIM card is provided to the user by the operator, and the user inserts a valid SIM card into the mobile terminal device, and the terminal device can pass the user identity identification and authentication of the operator's network, otherwise the network cannot be registered and used. In recent years, with the vigorous development of the mobile Internet, the variety of mobile terminal equipment has become more and more abundant, and a large number of SIM cards ...
