Embodiment Construction

[0023] In the prior art, in an existing multi-card mobile terminal, when one of the subscriber identification cards generates a service request, the multi-card mobile terminal will establish a corresponding data transmission path for the subscriber identification card and the network. When multiple subscriber identification cards generate service requests at the same time, the multi-card mobile terminal needs to establish a corresponding data transmission path for each subscriber identification card. That is to say, in the existing multi-card mobile terminal that can provide services for multiple subscriber identification cards at the same time, there is a one-to-one correspondence between the established data transmission path and the subscriber identification card, resulting in the hardware cost of the multi-card mobile terminal. and higher complexity.

[0024] Aiming at the problems in the prior art, a multi-card mobile terminal has appeared, which can use the same data tra...

Abstract

The multi-card mobile terminal and its service switching method and device, the service switching method of the multi-card mobile terminal includes: when switching the network mode, switching the data transmission path in the current network mode that executes the multi-card service to the target network data transmission path under the mode; update the mapping relationship between the service identification of the corresponding subscriber identity card and the data transmission path in the current network mode to the mapping relationship between the service identification of the corresponding subscriber identification card and the data transmission path in the target network mode; The multi-card service is performed based on the updated mapping relationship between the service identifier and the data transmission path in the target network mode. The above solution can realize the connection of multi-card services of multi-card mobile terminals using the same data transmission path to perform multi-card services when the network mode changes.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-card mobile terminal and a service switching method and device thereof. Background technique [0002] Mobile terminals refer to computer devices that can be used on the move, broadly speaking, they include mobile phones, notebooks, tablet computers, POS machines, and vehicle-mounted computers. With the successive commercialization of various mobile network protocols, it has become a common phenomenon to cover multiple network signals in the same area, which has triggered fierce competition among operators operating different mobile networks and brought more choices to users. . In order to facilitate users to flexibly select a mobile network according to their own needs, most mobile terminals have a multi-card multi-standby function, that is, a multi-card mobile terminal. [0003] In an existing multi-card mobile terminal, when multiple subscriber identification c...
