Embodiment 1

[0103] As an aspect of this embodiment, an emergency public broadcasting method under a 5G network is provided. like figure 1 As shown, the emergency public broadcasting method includes the following steps S100 to S400.

[0104] S100. The broadcast control system pushes the audio and video content to be broadcast to each CDN master node, wherein each CDN master node refers to the audio and video content CDN core node of each video application; the video application is the video APP (abbreviation for Application), referring to It is a video application software installed on a smart terminal (such as a smart phone), such as the existing Tencent Video, iQiyi, Youku Video, Sohu Video and Baidu Video, etc.;

[0105] S200. The NEF wakes up the built-in video application of the target UE, and obtains the identification code of the awakened video application;

[0106] S300.NEF selects the address of the corresponding CDN master node and the entry address of the audio and video conte...

Embodiment 2

[0187] This embodiment provides an emergency public broadcasting system under a 5G network. like image 3 As shown, the emergency public address system includes: broadcast control system 100 , NEF200 and UE300 ; UE300 has a built-in video application 301 .

[0188]Wherein, the broadcast control system 100 is used to push the audio and video content ready to broadcast to each CDN master node 700, wherein each CDN master node 700 refers to the audio and video content CDN core node of each video application; the video application is the video APP (Application's Abbreviation), refers to the video application software installed on smart terminals (such as smart phones), such as the existing Tencent Video, iQiyi, Youku Video, Sohu Video and Baidu Video, etc.;

[0189] The NEF200 is used to wake up the built-in video application 301 of the target UE, and obtain the identification code of the awakened video application 301;

[0190] The NEF200 is also used to select the address of t...

Abstract

The invention provides an emergency public broadcasting method and system under a 5G network. The method comprises the following steps that: a broadcast control system pushes audio and video contents to be broadcasted to each CDN main node; the NEF awakens the built-in video application of the target UE and obtains the identification code of the awakened video application; the NEF selects the address of the corresponding CDN main node and the entry address of the audio and video content to be broadcast or being broadcast according to the identification code of the awakened video application, and sends the selected address to the UE; and after the UE receives the CDN main node and the entry address of the video content, the awakened video application is enabled to interact with the CDN main node, and the video content is played. The video public emergency broadcast content is broadcasted to the public in real time by utilizing the 5G network, the bearing information amount is large, real-time online playing is supported, and the effect of real-time broadcasting is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an emergency public broadcasting method under a 5G network, and an emergency public broadcasting system under a 5G network.
