Embodiment 1

[0046] Embodiment 1 of the present invention proposes a method for enhancing the reliability of a SIM card. Such as 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 wit...

Embodiment 2

[0060] Embodiment 2 of the present invention proposes a terminal that enhances the reliability of a SIM card. Such as 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 includ...

Embodiment 3

[0068] Embodiment 3 of the present invention proposes a method for enhancing the reliability of a SIM card. Such as 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 whic...

Abstract

The present invention is applicable to the communication field, and provides a method and device for enhancing the reliability of a SIM card. The method includes the following steps: the terminal sends a registration request to the operator network in the NOSIM mode; so that the operator network according to the The registration request initiates an authentication process; according to the network random number issued in the authentication process, the hardware fingerprint information pre-stored at the local end, the IMSI information and the authentication file, the authentication operation is performed to obtain the first authentication value; the described The first authentication value is sent to the operator network for the operator network to verify the first authentication value according to the backup hardware fingerprint information to determine whether to allow the terminal to access the network. The method and equipment provided by the invention improve the reliability of the terminal connecting to the network without a 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 ...
