Embodiment Construction

[0054] The purpose of the present invention is to provide MCU-based video conferencing services in the IMS network environment, and provide rich user terminal access methods, that is, the user terminal can create and join MCU-based video conferencing. In the present invention, the access mode of the user terminal includes: the user terminal creates an instant video conference, creates a reserved video conference, invites other members to join the video conference, and actively joins the video conference.

[0055] In the technical scheme of the present invention, the video conferencing system based on the IMS environment, such as figure 1 As shown, it includes user terminal UE, IMS core network, AS, MCU and RMS.

[0056] The IMS core network is responsible for user terminal access and service triggering, the AS refers to an application server that carries video conferencing services, the MCU is a multipoint control unit responsible for processing video media, and the RMS is a ...

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 terminal.

Description

technical field [0001] The present invention relates to a method for implementing video conferencing services in an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) environment, in particular to an IMS network, using an Application Server (Application Server) based on a Session Initialization Protocol (SIP for short). Server, referred to as AS), a multipoint control unit (Multipoint Control Unit, referred to as MCU), and a resource management system (Resource Manager System, referred to as RMS) to realize the video conference service method. Background technique [0002] In the IMS environment, each network element communicates through the SIP protocol to perform signaling control. The IMS core network is mainly responsible for user terminal access, authentication and session control for user numbers, and triggering the business process of video conferencing. AS is an entity in the IMS network that implements business logic control, and can be used to build ...
