Abstract

The invention provides a service switching method and device for a multi-card terminal and a multi-card terminal. The method includes: during the process of the second subscriber identity card performing business through the current data transmission path of the first subscriber identity card, when a network mode switch occurs, establishing a data link based on the target network mode based on the second subscriber identity card a transmission path: switching the services performed by the second subscriber identity card through the current data transmission path of the first subscriber identity card to the data transmission path based on the target network mode. The invention can switch the data transmission path between different network modes to normally carry out business when the network mode changes.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-card terminal service switching method, device and multi-card terminal. Background technique [0002] With the continuous improvement of mobile network bandwidth and optimization of mobile device performance, users' requirements for services that mobile terminals can provide are also gradually increasing. At present, mobile terminal services have become more and more diversified from the traditional two-person call, adding services such as video call, call transfer, and multi-party call. In an existing multi-card call, a multi-card terminal can establish a data transmission path based on one card and perform services of multiple cards based on the data transmission path. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] When the network mode ch...
