[0037] 1. Encapsulation of emergency broadcast messages

[0038] 1) In the Mobile Multimedia Broadcasting (CMMB) emergency broadcasting system, the emergency broadcasting system is divided into national emergency broadcasting subsystem, local emergency broadcasting subsystem, frequency points assigned by national network and local network according to the difference of national emergency broadcasting and local emergency broadcasting The frequency points of the network in different places can be the same or different.

[0039] 2) In the mobile multimedia broadcasting (CMMB) system, multimedia broadcasting is divided into multiple channels by time division multiplexing, and these channels are described by multiplexing frames, and the channel marked as 0 is a control logic channel. The mobile multimedia broadcasting national network and local network have their own control logic channel.

[0040] 3) The emergency broadcast message provides the content and related information of ...

Abstract

The present invention discloses a method for transmitting local emergency broadcast information, wherein a mobile multimedia broadcast system is used for transmission. The method comprises the following steps: dividing the emergency broadcast system of mobile multimedia broadcast to a national emergency subsystem and a local emergency broadcast subsystem, wherein each emergency broadcast subsystem is corresponding with a mobile multimedia broadcast network; independently setting a control logic channel by each mobile multimedia broadcast network, wherein the emergency broadcast information is transmitted in the control logic channel; and only transmitting the local emergency information the control logic channel of the local mobile multimedia broadcast network. The invention simply and effectively realizes the transmission and receiving of local emergency broadcast information in the CMMB system and increases the reasonable use to the wireless broadcast resource.

Description

technical field [0001] The invention relates to mobile multimedia broadcast technology, in particular to a method for transmitting local emergency broadcast messages. Background technique [0002] Emergency broadcasting is a service that uses the broadcast communication system to quickly notify the public of emergency events. When emergencies such as natural disasters, accident disasters, public health and social security occur, which cause or may cause heavy casualties, property losses, ecological environment damage and serious social hazards, and endanger public safety, emergency broadcasting provides a rapid Quick way to notify. [0003] In the United States, Europe and other regions, a complete system of emergency broadcasting has been formed, and great results have been achieved in practical applications. However, my country's emergency broadcasting is still in the development stage, although the State Council has promulgated the "National General Emergency Plan for P...
