Embodiment Construction

[0042] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0043] For the convenience of describing the system and workflow of the present invention, the agreement is as follows:

[0044] 1. Mobile intelligent terminal: refers to portable devices such as smart phones, tablets, and wearables represented by Android, IOS, and Windows systems.

[0045] 2. Dual card dual standby: it can support dual (u) sim cards in standby under two network standards (such as WCDMA and GSM) at the same time, and perform voice or data services. According to different implementation methods and principles, it can be divided into dual-card dual-standby single-pass and dual-card dual-standby dual-pass.

[0046] 3. Dual-card dual-standby single-pas...

Abstract

The invention relates to a system and a method for realizing remote authentication of a subscriber identity module (SIM) card. The method comprises the steps that a physical card accesses a mobile communication network, position information of a cell which a user accesses is acquired, and whether the user is in a roaming state is determined; if the user is in the roaming state, a cloud card smart terminal switches the state of the physical card to a global system for mobile communications (GSM) network, switches the state of a cloud card to an long term evolution / wideband code division multiple access (LTE / WCDMA) network, and writes SIM card virtual number resource information acquired from a user identification card management server through a GSM data channel of the physical card in the cloud card; the cloud card smart terminal initiates a service request by use of a virtual number of the cloud card, and sends authentication data generated by the user identification card management server to mobile communication core network equipment to authenticate; a data channel of the cloud card smart terminal is switched to the LTE / WCDMA network of the cloud card; and the cloud card smart terminal uses the cloud card to perform voice or data communication through the mobile communication network. Through adoption of the system and method, the use cost of the user and power consumption of the terminal can be lowered.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a system and method for remote authentication of SIM cards of intelligent mobile terminals. Background technique [0002] At present, mobile smart terminals have been popularized, and Internet services can be obtained anytime, anywhere while moving, and have the advantages of "small and light" and "convenient communication". Today, the mobile communication network has developed to the LTE stage, with increased speed and reduced tariffs. The new mobile instant messaging service has sprung up suddenly. It not only has the characteristics of mobility and online at any time, but also integrates business functions such as text, picture, video and even voice. Instant messaging, social networking, sharing, meeting users' requirements for information acquisition, and the use of data-centric mobile devices have led to rapid growth of mobile network data. [0003] Bluetooth 4.0 inheri...
