Abstract

The invention provides a service switching method, a terminal, a network server, and a storage medium. A first terminal receives VoLTE voice service requests sent by a second terminal, wherein the VoLTE voice service requests include the identifier of a first UICC card of the first terminal; and the first terminal determines the working states of the first UICC card and a second UICC card according to the VoLTE voice service requests, and forwards a VoLTE voice service request that meets the preset service forwarding condition to the second UICC card according to the working states, thereby avoiding the interruption of the ongoing data service of the second UICC card due to the VoLTE voice service request of the first UICC card, and realizing the concurrence of the VoLTE voice and data onthe same UICC card.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a service switching method, a terminal, a network server, and a storage medium. Background technique [0002] With the continuous development of science and technology, mobile terminals have become an indispensable communication tool in people's daily life. At present, mobile terminals support dual-card dual-standby functions. Dual-card dual-standby means that one mobile terminal has two user identification cards. And the two user identification cards can be in the standby state at the same time, and both can realize communication services such as making or answering calls, sending and receiving short messages, and accessing the Internet. [0003] In the historical evolution of dual-card dual-standby, before there was no VoLTE (Voice over LTE, IMS-based voice service), voice services could only be carried on the 2G / 3G circuit domain, while dat...
