Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and the embodiments of the present invention can be applied to scenarios of various PWS types including CMAS.

[0022] see figure 1 , which is a flowchart of an embodiment of a method for broadcasting an alarm message in the present invention, and the method includes the following steps.

[0023] Step 101: Receive dedicated signaling, where the dedicated signaling includes an alarm message to be broadcast.

[0024] Step 102: Determine the priority of all alarm messages in the alarm system.

[0025] For example, when the dedicated signaling includes an alarm message type, the priority of the alarm message to be broadcast in the dedicated signaling is obtained according to the correspondence between the included alarm message type and th...

Abstract

The embodiment of the invention discloses a method and a device for broadcasting alarm information, wherein the method comprises the steps of: receiving a special signaling, wherein the special signaling comprises alarm information to be broadcast; determining priority levels of all alarm information in an alarm system; and broadcasting the alarm information to be broadcast according to the priority levels of the alarm information in the alarm system. According to the embodiment of the invention, under the condition of limited air interface resources, some very emergent or very important alarm information is preferentially sent, such PWS (Personal Web Server) alarm information or CMAS alarm information.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for broadcasting an alarm message. Background technique [0002] PWS (Public Warning System) is a system that warns of natural disasters or man-made accidents that may damage human life and property. When natural disasters or man-made accidents occur, PWS can be used as a supplement to the existing broadcast communication system to notify people of the situation in time through the mobile communication system. [0003] ETWS (Earthquake and Tsunami Warning System) and CMAS (Commercial Mobile Alert System) are two special types of PWS. The PWS defines requirements common to public alarm systems that must be met in both ETWS and CMAS. At the same time, ETWS and CMAS have their own requirements and characteristics, and the corresponding specific solutions are also different. Among them, ETWS is only for earthquake and tsunami warning. The situatio...
