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 functions, which has two SIM cards, both of which are 4G multi-mode SIM cards, both of which support VoLTE voice services, and both of which have two SIM cards. Support SRVCC to switch voice calls to UMTS or GSM. The 4G multi-mode SIM card supports automatic selection to reside in a 2G, 3G or 4G mobile communication network according to the network environment, for example corresponding to 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 a 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, reaching the limit of physical resources. full use of. For ease of description, the first SIM card is called SIM_A, and the second SIM c...

The invention discloses a data management method for a 4G multi-mode dual-card mobile terminal, and the method comprises the steps: reminding a user to select whether to carry out the SIM_A network mode switching or not when an SIM_B starts a data service, or an SIM card bearing the data service is switched from the SIM_A to the SIM_B; if the SIM_A resides in a 4G mobile communication network before, switching the SIM_A to reside in the 3G or 2G mobile communication network, and reporting, by the SIM_A,that the 4G mobile communication network is not supported when registering to the mobile communication network; when the SIM card bearing the data service is switched back to the SIM_A from the SIM_B, reporting, by the SIM_A, that the 4G mobile communication network is supported when registering to the mobile communication network; by the SIM_A, automatically deactivating the IMS and the PDN thereof, and reporting that the VoLTE is not supported when re-registering to the mobile communication network; and when the SIM card bearing the data service is switched back to the SIM_A from the SIM_B, by the SIM_A, reporting that the VoLTE is supported when re-registering to the mobile communication network, and activating the IMS and the PDN thereof. According to the application, the situation that the normal data service of the SIM card bearing the data service is interrupted due to the fact that the SIM card not bearing the data service frequently enters and exits from the connection state is avoided.
Description
technical field [0001] The present application relates to a data management method of a dual-card mobile terminal. Background technique [0002] 4G multi-mode mobile phones supporting GSM (Global System for Mobile communications, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) and LTE (Long Term Evolution, long-term evolution technology) 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, There is also a wide demand for 4G multi-mode mobile phones with dual SIM dual standby (DSDS, Dual SIM Dual Standby) function. [0003] For the convenience of description, in this application document, SIM (subscriber identity mod...
