Abstract: The present disclosure discloses a method and a system for automatically resuming a call after network handover, and belongs to the field of network calls. In the method of the present disclosure, during a call between a first terminal and a second terminal, when the first terminal is handed over from a first network to a third network, the first terminal first stores call resources, then registers with a server through the third network, constructs a resume request, and sends the resume request to the second terminal via the server, and the second terminal resumes the call with the first terminal according to the resume request. The present disclosure can ensure communication stability after network handover of a communication device, thereby avoiding call interruption caused by the network handover during communication of the communication device.

Abstract: The present disclosure discloses a multi-device recording synchronization method and system, and a conference system, and belongs to the field of recording marking. For the problem in the prior art that a device that supports a recording marking function only supports generation and use on a single device, the present disclosure provides a system, including one master and a plurality of slaves. The master is connected to the plurality of slaves. The master operates according to the instruction sent by the slave and broadcasts state information globally. Through a network connection between the master and the slave, the master stores, on the master, recording and marking data sent by the slave, and synchronizes the data between devices, and a multi-device recording marking and synchronization system is applied to a conference system. The present disclosure is very convenient for use and has simple operation logic and low system costs.
