In this embodiment, at a time when the SIM card needs to be authenticated (e.g. when a user first accesses a network, powers on, etc.), the mobile terminal obtains n IMSI numbers of the SIM card, sends a network access request of the n IMSI numbers of the SIM card to a core network of an operator through a background server, and after the core network receives the n network access requests, returns a corresponding authentication request to a background server for each network access request, because for each IMSI, communication channels between the background server and the core network of the operator are in one-to-one correspondence, that is, one IMSI corresponds to a communication channel between the background server and the core network, when the background server receives the authentication request sent by the core network, it can know which IMSI the authentication request is for according to the communication channel from which the authentication request is from, and add the card number identifier of the IMSI to the authentication request, and the processed authentication request is sent to the SIM card through the mobile terminal, so that the security module of the SIM card can call corresponding card number authentication data according to the card number identification in the processed authentication request, and then the security module communicates with an operator core network through the mobile terminal and a background server to complete the network access authentication of each IMSI of the SIM card.

In the prior art, the specific implementation modes of SIM card network authentication are various, and in practical application, an authentication method can be selected according to actual needs.
After the network access authentication of each IMSI of the SIM card is completed, the MSISDN number corresponding to the IMSI passing the authentication is in an online state, that is, the call or short message information and the like sent by other user terminals through the core network can be received. Namely, the method provided by the invention further comprises the following steps:
step S5: the background server receives a first instruction sent by an operator core network, adds a card number identifier of the IMSI corresponding to a channel into the first instruction according to a source channel of the first instruction to obtain a second instruction, and sends the second instruction to the mobile terminal;
step S6: and the mobile terminal sends the second instruction to the SIM card, and the SIM card calls the corresponding card number data according to the card number identification in the second instruction to process the instruction.
The first instruction includes, but is not limited to, a call instruction or a short message instruction. After receiving the second instruction, the SIM card specifically needs to call which card number data is determined by the type of the instruction.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
