Embodiment Construction

[0027] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0028] The method for sending the indication information of the ETWS message includes: when the ETWS message needs to be released, the base station sends the indication information of the ETWS message to the connected state terminal through dedicated signaling on a dedicated channel.

[0029] The method for receiving the ETWS message indication information includes: the terminal in the connected state receives the dedicated signaling from the dedicated channel, and obtains the indication information of the ETWS message therefrom. Receive ETWS messages instantly.

[0030] The above-mentioned dedicated signaling may be RRC (radio resource control) layer signaling (for example, the paging message of the existing RRC layer may be used as dedicated signaling), or MAC (media access control) layer signaling, or physical Layer PDCCH (Physical...

Abstract

The invention discloses a method for transmitting and receiving indication information of earthquake and tsunami warning system message, applicable to a connection status terminal which is enabled toreceive the ETWS message in time. The transmission method comprises the step that a base station transmits the indication information of the ETWS message to the connection status terminal through a special signaling on a special channel when an earthquake and tsunami early warning system message is to be issued, wherein the indication message is used for indicating whether an ETWS message is to beissued exists or not. The reception method comprises the steps as follows: a terminal in the connection status receives the special signaling from the special channel to obtain the indication information of the earthquake and tsunami warning system ETWS message, and the terminal receives the ETWS message immediately according to the indication information.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for notifying a connected state terminal to read an ETWS (Earthquake and Tsunami Warning System, Earthquake and Tsunami Warning System) message. Background technique [0002] In order to actively respond to natural disasters such as earthquakes and tsunamis, it is necessary to establish a set of ETWS. By using this system, when an earthquake and tsunami natural disaster occurs, disaster-related information can be sent to users in a timely manner, thereby reducing the impact of the earthquake and tsunami natural disaster on human beings. [0003] figure 1 It is a network structure diagram of a PLMN (public land mobile network) operator providing earthquake and tsunami warning services to users through the ETWS system. When a disaster event is about to occur or occurs, the government or other agencies issue an alarm notification to the PLMN operator, and the PLMN operator se...
