Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides a method for non-joint attachment of a dual-card dual-standby mobile terminal. include:

[0032] S1: Start the dual registration process of 4G multi-mode card and 3G / 2G card. MSC associates the IMSI of 4G multi-mode card with the IMSI of 3G / 2G card, and completes the dual registration of 4G multi-mode card and 3G / 2G card in HLR. register;

[0033] S2: Establish a call process. When there is an incoming call to call the 4G multi-mode card, the MSC sends the paging request to the 3G / 2G card according to the association relationship between the IMSI of the 4G multi-mode card and the IMSI of the 3G / 2G card, and the 3G / 2G card receives it. Paging request and send a paging response to MSC to establish a call.

[0034]The 4G multimode card of the mobile terminal is mainly used to undertake the data flow service. When the data flow service needs to be used, the 4G multimode card can be turned on, and when not in use, ...

Embodiment 2

[0050] On the other hand, according to the same idea of ​​the present invention, the present invention also provides a dual-card dual-standby mobile terminal non-union attached call system, including:

[0051] Dual-card dual-standby mobile terminal 1, the dual-card includes 4G multi-mode card and 3G / 2G card;

[0052] MSC2 is used to associate the IMSI of the 4G multimode card with the IMSI of the 3G / 2G card; and,

[0053] HLR3, used to complete dual registration of 4G multimode card and 3G / 2G card;

[0054] When the 4G multi-mode card of the dual-card dual-standby mobile terminal 1 has an incoming call, the MSC2 is also used to send a paging request to the 3G / 2G card, the 3G / 2G card of the dual-card dual-standby mobile terminal is used to receive a paging request and send a paging response to MSC2 to establish a call.

[0055] Further, the 3G / 2G card is also used to send a dual registration request message to MSC2, the message type indicates a dual registration message, and...

Abstract

The present invention provides a method and a system for non-jointly attaching a dual-card dual-standby mobile terminal, wherein the dual-card dual-card dual-standby mobile terminal includes a 4G multi-mode card and a 3G / 2G card, and the method includes: The dual registration process of the multi-mode card and the 3G / 2G card, the MSC associates the IMSI of the 4G multi-mode card with the IMSI of the 3G / 2G card, and completes the registration of the 4G multi-mode card and the 3G / 2G card at the HLR; establishes the call process, When there is an incoming call to call the 4G multi-mode card, the MSC sends a paging request to the 3G / 2G card according to the relationship between the IMSI of the 4G multi-mode card and the IMSI of the 3G / 2G card, and the 3G / 2G card sends a paging response to the MSC. Make a call. The method and system for non-jointly attaching a call of a dual-card dual-standby mobile terminal in the present invention solves the problem that the 4G multi-mode card realizes the voice call process is complicated, and the call establishment time is relatively long, and can be implemented after the 4G multi-mode card is turned off. The establishment of 4G multi-mode card calls further improves the user experience of using mobile terminals.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for non-union attached communication of a dual-card dual-standby mobile terminal, and a system for non-union-attached communication of a dual-card dual-standby mobile terminal. Background technique [0002] At present, a relatively popular configuration of mobile terminals is dual-card dual-standby. Dual card means that there are two card slots on the mobile terminal, which can install two USIM (Universal Subscriber Identity Module, Global Subscriber Identity Module) / SIM (Subscriber Identity Module, Subscriber Identity Module) cards, and each USIM / SIM card can support one Or multiple network standards, two USIM / SIM cards can belong to the same operator, or can belong to different operators. The dual standby function means that when the two USIM / SIM cards support different network standards, the mobile terminal supports two USIM / SIM cards that are successf...
