Embodiment 1

[0046] Embodiment 1 of the present invention proposes a method for enhancing the reliability of a SIM card. like figure 1 As shown, the method of Embodiment 1 of the present invention includes the following steps:

[0047] S11. The terminal sends a registration request to the operator network in NOSIM mode.

[0048] Before executing step S11, the terminal backs up the hardware fingerprint information of the terminal to the operator's network in advance. There are many backup methods. For example, when the terminal is shipped or sold, the hardware fingerprint information is sent to the operator's network for backup. The terminal first registers with the operator's network through the built-in authorized SIM card, and then sends the hardware fingerprint information of the terminal as the authentication key to the operator's network for backup after successful registration. The registration of the authorized SIM card to the operator's network is carried out in accordance with t...

Embodiment 2

[0060] Embodiment 2 of the present invention proposes a terminal that enhances the reliability of a SIM card. like figure 2 As shown, the terminal in Embodiment 2 of the present invention includes a first registration module 21, a first sending module 22, a saving module 23, a first authentication module 24 and a request verification module 25, wherein:

[0061] The first registration module 21 is configured to register the operator network by authorizing the SIM card so that the operator network initiates an authentication process according to the registration request.

[0062] The first sending module 22 is configured to send the hardware fingerprint information of the terminal as an authentication key to the operator's network for backup, and send a registration request to the operator's network in the NOSIM mode. The hardware fingerprint information is identification information that uniquely identifies the terminal, and the hardware fingerprint information may include b...

Embodiment 3

[0068] Embodiment 3 of the present invention proposes a method for enhancing the reliability of a SIM card. like image 3 As shown, the method of the embodiment of the present invention includes steps:

[0069] S31. The server of the operator network receives the registration request sent by the terminal in NOSIM mode, and initiates an authentication process. Before executing step S31, the server backs up the hardware fingerprint information of the terminal in advance as the authentication key. There are many backup methods. For example, when the terminal leaves the factory or is sold, the hardware fingerprint information is sent to the server for backup. After the built-in authorized SIM card is successfully registered, the hardware fingerprint information of the terminal is sent to the server for backup. The registration mode of the authorized SIM card is performed according to the traditional SIM mode. In the second embodiment of the present invention, the mode in which t...

Abstract

The invention is applied in the communication field, and provides a method and equipment to enhance SIM card reliability. The method to enhance SIM card reliability comprises the following steps that a registration request is sent to an operator network by a terminal under an NOSIM mode; an authentication process is facilitated to be launched by the operator network according to the registration request; an authentication calculation is carried out according to a network random number, hardware fingerprint information pre-stored in a home terminal, IMSI information and an authentication file issued by the authentication process to obtain a first authentication value; the first authentication is sent to the operator network so that the operator network examines the first authentication value according to a backup copy of the hardware fingerprint information to judge whether the terminal is permitted to be connected to the network. The method and equipment to enhance SIM card reliability improves terminal reliability of networking without the SIM card.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method and equipment for enhancing the reliability of a SIM card. Background technique [0002] With the popularization of 3G smart phones, the mobile Internet is promoting and moving towards the interconnection mode of things and things (M2M); as the wireless access entity of the future Internet of Things, the wireless communication terminal module will face a broader Application scenarios. The terminal access mode of "SIM card + terminal equipment" has gradually exposed the technical defects of the traditional mode. When the SIM card in the terminal is damaged, the terminal cannot normally connect to the operator's network. Virtual SIM card technology can solve the problems of traditional SIM cards. Patent [CN200880125971.1] and patent [CN201210092772.3] respectively focus on two similar implementation methods of virtual VSIM; [CN200880125971.1] store VSIM files in the ...
