Abstract

The invention provides a callback method and a device, electronic equipment and a storage medium. The method comprises the following steps: a first terminal device initiates a session request to the second terminal device through the first user identification card, wherein the session request comprises a first identifier, the first identifier is used for the second terminal device to initiate a callback request to the first terminal device through the first identifier, and the first identifier comprises an identifier of a first subscriber identity module card and / or an identifier of at least one second subscriber identity module card; and the first terminal device receives a callback request sent by the second terminal device according to the first identifier. According to the callback method, callback of the first terminal device is realized, and the call completion rate of callback of the terminal device can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular to a callback method, device, electronic equipment and storage medium. Background technique [0002] At present, the functions of mobile terminals are becoming more and more powerful, especially the maturity and large-scale commercialization of the third-generation mobile communication network and the fourth-generation mobile communication network, which can enable electronic devices such as mobile terminals to transmit multimedia data such as voice and video at the same time . In addition, the data processing capabilities of mobile terminals are becoming more and more powerful, and the new generation of interactive methods represented by voice recognition technology on mobile terminals is becoming more and more mature, which can further help the user experience and performance of emergency calls. [0003] In the prior art, usually after the first terminal de...
