Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] figure 1 It shows an architecture diagram of a system for realizing simultaneous online multiple numbers of a mobile terminal in a specific embodiment of the present invention. It can be seen from the figure that the system includes a SIM card, a mobile terminal and an access operator's core network background server, and the SIM card communicates with the background server through the mobile terminal.

[0039] In this embodiment, n International Mobile Subscriber Identity codes IMSI are stored in the SIM card, one IMSI corresponds to one MSISDN number, n>1; correspondingly, the operator core network also stores n sets of card numbers of the SIM card Relationship (one-to-one correspondence between n IMSIs and n MSISDN numbers).

[0040] The SIM card includes a security module, and the security module is used to store n sets o...

Abstract

The invention discloses a system and a method for realizing one card and multiple numbers of a mobile terminal to be online simultaneously, and belongs to the technical field of mobile communication. In the system and method, the SIM card communicates with the operator's core network through the mobile terminal and the background server that accesses the operator's core network. After receiving the authentication request sent by the operator's core network, the background server will first send the IMSI The card number identifier is added to the authentication request and then sent to the SIM card through the mobile terminal, so that the SIM card can call the correct card number authentication data according to the card number identifier to complete the network access authentication of its IMSI. The system and method described in the present invention realize simultaneous online with one card and multiple numbers without adding additional equipment, and ensure the correct transmission and processing of instructions issued by the core network.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a system and method for realizing simultaneous online of one card and multiple numbers of a mobile terminal. Background technique [0002] One card multi-number service is a value-added service for all user groups, which means that one SIM card of a subscriber identity identification module corresponds to multiple numbers. In the prior art, one card multi-number service is realized mainly by setting one number as the primary number and the others as secondary numbers, and by putting the card number data of the primary number in the standard file position to realize its network access authentication, which needs to be used When using other numbers, set the other numbers as the main number and perform network access authentication to make them online. But at the same time, only one number can be online. Contents of the invention [0003] Aiming at the defects exist...
