Problems solved by technology
Before the connection is established, the mobile terminal cannot confirm that it is the VoLTE voice called paging, so that the non-data service bearer card may receive irrelevant packet-switched paging of the card and frequently interrupt the data service bearer Card continuous standby or data service
This leads to the frequent entry and exit of the SIM card that does not carry data services and interrupts the normal data service of the SIM card that carries data services, seriously affecting the user experience of VoLTE 4G multi-mode dual-card mobile terminals in such scenarios

Embodiment Construction
[0029] In this application, a 4G multi-mode dual-card mobile terminal refers to a 4G multi-mode mobile terminal with dual-card dual-standby function, which has two SIM cards, both of which are 4G multi-mode SIM cards, and both support VoLTE voice services. Support SRVCC to switch voice calls to UMTS or GSM. The 4G multi-mode SIM card supports the automatic selection to reside in the 2G, 3G or 4G mobile communication network according to the network environment, for example corresponding to the GSM, UTMS or LTE network respectively. Both SIM cards support voice services and data services. The VoLTE 4G multi-mode dual-card mobile terminal only needs one set of 2G, 3G, and 4G radio frequency transceivers, so that at any time, only one of the voice services or data services can be performed on a certain SIM card to achieve physical resources. full use. For convenience of description, the first SIM card is called SIM_A, and the second SIM card is called SIM_B; the actions of the ...

This application discloses a data management method for a 4G multi-mode dual-card mobile terminal. When SIM_B enables data services, or the SIM card carrying data services is switched from SIM_A to SIM_B, the user is prompted to choose whether to switch the network mode of SIM_A. If SIM_A resides on the 4G mobile communication network before, SIM_A changes to reside on the 3G or 2G mobile communication network at this time, and at the same time, SIM_A reports that it does not support the 4G mobile communication network when registering with the mobile communication network. When the SIM card carrying the data service is switched back from SIM_B to SIM_A, SIM_A reports to support the 4G mobile communication network when registering with the mobile communication network. SIM_A automatically deactivates IMS and its PDN, and SIM_A reports that it does not support VoLTE when re-registering with the mobile communication network. When the SIM card carrying the data service is switched back from SIM_B to SIM_A, SIM_A reports support for VoLTE when re-registering with the mobile communication network, and activates the IMS and its PDN. The application avoids the interruption of the normal data service of the SIM card carrying the data service due to the frequent entry and exit of the SIM card not carrying the data service into and out of the connected state.
Description
technical field [0001] The present application relates to a data management method for a dual-card mobile terminal. Background technique [0002] 4G multi-mode mobile phones that support GSM (Global System for Mobile communications, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) and LTE (Long Term Evolution, Long Term Evolution technology) at the same time have been obtained. widely used. However, 4G multi-mode mobile phones still cannot meet the needs of some specific users. For example, users want to have two different phone numbers, or users want to use different services (voice, SMS, Internet services, etc.) of different mobile communication operators at the same time. Therefore, 4G multi-mode mobile phones with Dual SIM Dual Standby (DSDS) function are also in wide demand. [0003] For the convenience of description, in this application document, the SIM (subscriber identity modul...
