Description

Method and system for dual-card dual-standby mobile terminal non-union attached call

technical field

Background technique

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 successfully registered on the two networks and are on standby at the same time; when the two USIM/SIM cards support the same network standard, the mobile terminal supports two USIM/SIM cards successfully registered on the same network and standby at the same time.

For dual-card dual-standby mobile terminals, when one of the cards is a 4G multi-mode card and the other is a 3G/2G card, if the 4G multi-mode card selects CSFB (Circuit Switched FallBack) technology to realize voice calls, The 4G multi-mode card first needs to implement the joint attachment process; at the same time, the CSFB call includes the CSFB fallback phase,

3G/2G side RRC (RadioResourceControl, radio resource control) access phase and call establishment phase. Among them, the CSFB fallback stage includes inter-system cell measurement, reporting measurement reports, etc.; the 3G/2G side RRC access stage includes synchronization, system message reading, RRC establishment, etc. Due to the complexity of the CSFB call process, the call establishment time is relatively long, and when the dual-card dual-standby mobile terminal does not need to use the 4G multi-mode card for data traffic services, in order to prevent missed calls, it is also necessary to open the 4G multi-mode card, resulting in dual-card The battery consumption of dual standby mobile terminals is relatively fast, and the user experience is not good.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment one

As shown in Figure 1, the present invention provides a method for non-union attachment and calling of a dual-card dual-standby mobile terminal. Attachment methods include:

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 process of 4G multi-mode card and 3G/2G card in HLR. register;

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.

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, the 4G multimode card can be turned off. The association relationship with the IMSI of the 3G/2G card, when the 4G multi-mode card is turned off, the call to the 4G multi-mode card will be established through the 3G/2G card, so that the 4G multi-mode card does not need to be attached jointly, and does not need to fall back to establish a call , preventing the speed of data traffic from being affected, saving energy consumption and improving user experience.

It should be noted that there is no limit to the number of 4G multi-mode cards in the mobile terminal, it can be 2 or more, and of course it can also be 5G or other similar multi-mode cards.

Further, before starting the double registration process of the 4G multi-mode card and the 3G/2G card, it also includes: attaching the 4G multi-mode card to the EPC network.

EPC, short for Evolution of Core Packet Network in Chinese, is the core network of 4G. The core network equipment in EPC includes mobility management equipment (MME), serving gateway (S-GW), PDN gateway (P-GW) and storage user The HSS of the subscription information and the unit for charging and policy control (PCRF), etc., attach the 4G multi-mode card to the EPC network, and the 4G multi-mode card can be used to complete the fast data traffic service, and the steps of joint attachment are faster Simple.

As shown in Figure 2, further, before the MSC associates the IMSI of the 4G multi-mode card with the IMSI of the 3G/2G card, it also includes: the 3G/2G card sends a double registration request message to the MSC, and the double registration request indicates The message type is a dual registration message, which includes the IMSI of the 4G multi-mode card and the IMSI of the 3G/2G card, and specifies the IMSI type of the 4G multi-mode card and the type 201 of the IMSI of the 3G/2G card.

The 4G multi-mode card authenticates the authentication response information. The mode card sends the user response to the 3G/2G card, the 3G/2G card sends the user response to the VLR, and the VLR sends the user response to the HLR, and the HLR completes the registration 204 of the 4G multi-mode card after passing the authentication.

Complete the registration of the 4G multi-mode card in the HLR through the 3G/2G card, and associate the IMSI of the 4G multi-mode card with the IMSI of the 3G/2G card, so that the call from the 3G/2G card to the 4G multi-mode card can be sent to the MSC Respond to paging and establish a call.

Further, the MSC includes a VLR; the HLR completes the registration of the 3G/2G card including: the VLR sends the IMSI authentication request 205 of the 3G/2G card to the HLR, and the HLR returns an authentication response to the VLR; the VLR sends the authentication response Send to the 3G/2G card, after the 3G/2G card authenticates the authentication response information, calculate the user response 206 of the relevant information, the 3G/2G card sends the user response to the VLR; the VLR sends the user response to the HLR, and the HLR After the authentication is passed, the registration 207 of the 3G/2G card is completed.

After the registration of the 4G multi-mode card is completed, the registration of the 3G/2G card is completed in the HLR, and the IMSI and location information of the 4G multi-mode card and the 3G/2G card are saved in the HLR.

Further, before the MSC sends the paging request to the 3G/2G card, the caller sends the call request to the MSC according to the location information of the 4G multimode card in the HLR, and then the MSC sends the paging request to the MSC according to the IMSI of the 4G multimode card and the 3G/2G card The associated relationship of the IMSI sends the paging request to the 3G/2G card.

When there is an incoming call to call the 4G multi-mode card, no matter whether the 4G multi-mode card is turned off or on, the call establishment can be completed. The call establishment process includes:

Step S310: The caller sends a call request to the MSC according to the location information of the 4G multi-mode card in the HLR;

Step S320: The MSC sends the paging request to the 3G/2G card according to the relationship between the IMSI of the 4G multimode card and the IMSI of the 3G/2G card;

Step S330: The 3G/2G card sends a paging response to the MSC according to the destination address in the paging request being the IMSI of the 4G multi-mode card, and establishes a call.
