Embodiment 1

[0052] Embodiment 1 of the present invention proposes a method for virtual SIM card. Such as figure 1 As shown, the method of Embodiment 1 of the present invention includes the following steps:

[0053]Step S1, pre-installing data required for authentication into the terminal. IMSI number (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number), ICCID number (Integrate Circuit Card Identity, integrated circuit card identification code), PLMN (Public Land Mobile Network, public land mobile network) and other file content, and authentication Contents such as the authorization key, the first authentication algorithm, and the second authentication algorithm are stored in the terminal in advance, and are usually built into the terminal when the terminal leaves the factory.

[0054] The above-mentioned authentication key is usually 16Byte, provided by the operator of the mobile network, stored in the non-volatile storage of the...

Embodiment 2

[0063] Embodiment 2 of the present invention proposes a virtual SIM card device. Such as figure 2 As shown, the device of Embodiment 2 of the present invention includes:

[0064] The request module 10 is configured to send an access request to the mobile network by the terminal when the terminal needs to access the mobile network, so that the mobile network can issue an authentication parameter according to the access request; the authentication parameter includes a random number, authentication token and network authentication value;

[0065] A network authentication module 20, configured to authenticate the mobile network according to the authentication parameters;

[0066] The terminal authentication module 30 is configured to accept the authentication of the mobile network.

[0067] Such as image 3 As shown, the network authentication module 20 includes:

[0068] The first calculation unit 21 is configured to calculate a first authentication value according to the b...

Embodiment 3

[0084] Embodiment 3 of the present invention proposes a mobile terminal. Such as Figure 5 As shown, the mobile terminal according to Embodiment 3 of the present invention includes a device 100 of a virtual SIM card, and the structure and working principle of the device are the same as those of Figure 2 to Figure 4 The devices shown are similar and will not be repeated here.

Abstract

The invention relates to the field of communication, and provides a method, device and system of a virtual SIM card. The method comprises the steps that when a terminal needs to have access to a mobile network, the terminal sends access requests to the mobile network, so that the mobile network can issue authentication parameters according to the access requests; the authentication parameters comprise random numbers, authentication tokens and network authentication weight values; authentication is carried out on the mobile network according to the authentication parameters. The method, device and system of the virtual SIM card achieve the operation that an operator network can be accessed without the SIM card.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a virtual SIM card method, device and mobile terminal. Background technique [0002] A SIM card (Subscriber Identity Module, user identification card) or USIM card (Universal Subscriber Identify Module, global subscriber identification card) is a smart card. A SIM / USIM card uniquely identifies a customer and is a certificate for a user to register and access the network. For a terminal user, the SIM / USIM card has the following four functions: 1. User data storage function. Such as International Mobile Subscriber Identification Number (IMSI), authentication key (K), etc.; 2. User security management functions, such as PIN code, PUK code operation and management; 3. User identity authentication function, which provides authentication algorithms and authentication results to mark the legal identity of the user, so that the user can smoothly access the network; fourth, operator...
