Method and system for authenticating remote SIM of multi-card mode intelligent terminal

Abstract

The invention discloses a method for authenticating a remote SIM of a multi-card mode intelligent terminal. The multi-card mode at least comprises a first communication module and a second communication module, a first SIM card corresponding to the first communication module comprises a PS domain, a second SIM card corresponding to the second communication module comprises a CS domain, and in the state that the first communication module cannot be connected to a network, the problem of acquiring identity information of the remote client identification module (Remote-SIM) in a non-network communication state through a short message channel is solved. The invention further discloses a system for authenticating the remote SIM of the multi-card mode intelligent terminal. When the first module cannot be connected to the network, application that the first module utilizes the remote SIM is achieved with the help of the short message domain of the other module by using a short message as a card calling channel, and the method and system are mainly applied to mobile terminal equipment such as a mobile phone and smart home.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for realizing authentication by a remote SIM of a multi-card mode intelligent terminal. Background technique [0002] CS domain: circuit bearer domain, providing voice service and fax service (short message). [0003] PS domain: data domain, used for mobile Internet access, etc., which also includes streaming media services, VOIP, etc. [0004] The use of remote SIM technology can effectively solve user demand scenarios such as multi-network coverage, dynamic card adjustment, and cross-border roaming. However, due to the specific requirements of the current remote SIM technology for hardware terminals, one of the modules is pre-configured with a SIM card and has a data path. Using this data path, a remote SIM is invoked for another independent module. That is, the hardware requires the terminal device to have two independent modules, or the terminal platform has ...

Problems solved by technology

However, the former increases the cost of hardware and the difficulty of hardware design, and at the same time increases the hardware volume of the product and increases the power consumption of the product; the latter cannot be realized at present due to the limitation of the terminal platform provider's solution (taking mobile phones as an example, the current market There are very few mobile phones on the Internet that can use dual cards, dual standby, dual communication, and dual traffic at the same time)
