Embodiment Construction

[0060] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0061] In view of the defects in the video forwarding process in the prior art, such as figure 1 , figure 2 with image 3 As shown, in the video forwarding strategy, after the DC has established a call with the video source, it goes back to the H-TCF2 where the video source is located to forward the video, which increases the signaling overhead of the core network; in the video push to gro...

Abstract

The present invention provides a method and system for forwarding video to a group in a broadband cluster, including: DC requests to the G-TCF where the video is located through the H-TCF, and sends a group establishment request to the V-TCF / V-eMME where the group members are located, Send a group call video connection establishment request to the eNodeB corresponding to the group member based on the minimized group call area; after the group call video connection is established, the video is forwarded to the group members through the TMF where the DC is located; the DC forwards the group release request to the G through the H‑TCF ‑TCF, sends a group release request to V‑TCF / V‑eMME, and V‑TCF / V‑eMME sends a group call video connection release request to eNodeB. In the present invention, the video forwarding is directly performed from the TMF where the DC is located, thereby reducing the signaling interaction between the H-TCF where the DC is located and the H-TCF where the video source is located, and improving the stability of the system.

Description

technical field [0001] The invention relates to the technical field of broadband cluster communication, in particular to a method and system for forwarding video to a group in a broadband cluster. Background technique [0002] Broadband trunking communication technology has been developed since the 1970s, involving many multimedia services, including voice single call, voice group call, video single call, video group call, video push, video pull-up and video forwarding and other characteristic trunking functions. These functions are widely used in industries such as rails, bridges, and tunnels. Among them, video forwarding is a characteristic service of cluster communication. The dispatcher DC (Dispatcher) sends a SIP (Session Initiation Protocol) message through H-TCF (Home-Trunking Control Function) to notify the core network and the cluster The core network forwards the existing video to the terminals of the specified group, and the terminals in the group receive the gro...
