TLDR
In this paper, a method for realizing video conference service in the IMS environment is presented, where user terminals transmit request messages to an IP Multimedia Subsystem IMS core network.Abstract:
The present invention provides a method for realizing video conference service in the IMS environment, including: a step A: user terminals transmit request messages to an IP Multimedia Subsystem IMS core network, and the IMS core network forwards the request messages to the application server AS triggering business meeting; a step B: AS transmits conference resource application messages to a resource management system RMS, and the RMS appoints a multi-point control unit MCU apparatus for the conference, AS transmits request establishing conference message to the appointed MCU apparatus, the MCU establishes a conference, and returns backs the result to the AS; and a step C: after the MCU successfully creates the conference, the AS transmits the request message of the terminal to the MCU, the request message carries the session description protocol SDP of the user terminal, the MCU and the user terminal performs SDP media negotiation to establish an SIP session The present invention has enriched the access mode of the user terminalread more
