AI Technical Summary

Technical Problem

Existing technologies cannot efficiently conduct Internet Protocol Multimedia Subsystem (IMS) services through satellite communication systems, resulting in frequent connection release and establishment processes, which wastes resources and affects the service experience.

Method used

By maintaining the connection established by the control plane in the satellite communication system, even when there is no data transmission, the connection is used to transmit IMS data packets, enabling service interaction through the control plane connection, and managing the maintenance and release of the connection through timers when necessary.

Benefits of technology

This reduces signaling operations, avoids resource waste, and improves the transmission efficiency and service experience of IMS services.

Abstract

The embodiments of the present disclosure relate to a communication method, a communication device, a communication system, a storage medium and a program product. The communication method may be executed by a first node. The method comprises: receiving first information, wherein the first information is used for indicating the holding of a first connection, the first connection is a connection established on a control plane, and the first connection is used for transmitting an Internet protocol multimedia subsystem (IMS) data packet, and the holding of the first connection refers to not releasing the first connection when no data is transmitted on the first connection. In the present disclosure, on the one hand, a terminal can realize service interaction with an IMS system by means of a first connection established on a control plane for transmitting IMS data; and on the other hand, a network device may still not release the first connection on the basis of first information when no IMS data is transmitted, thereby avoiding resource waste caused by frequent release and establishment of connections, thus improving the transmission efficiency.
