Embodiment Construction

[0029] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, a method, user equipment, and system for obtaining ETWS messages according to the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] like figure 1 As shown, Embodiment 1 of the present invention provides a method for obtaining ETWS messages, including the following steps:

[0031] S11. Acquiring ETWS change indication information;

[0032] S12. Acquire the ETWS message when the ETWS change indication information indicates adding or updating the ETWS message.

[0033] like figure 2 As shown, Embodiment 2 of the present invention provides a method for obtaining ETWS messages, including the following steps:

[0034] S21. Knowing that the ETWS message has changed, and sending ETWS change indication information, the ETWS change indication information is used to indicate the change of the ETWS ...

Abstract

The embodiment of the invention discloses a method for acquiring an ETWS message, which comprises the following steps that: a UE acquires change indication information of an earthquake and tsunami warning system (ETWS); and when the change indication information of the ETWS indicates an added or updated ETWS message, the UE acquires the ETWS message. The embodiment of the invention also disclosesa method for sending the ETWS message. In the embodiment, due to the transfer of the change indication information of the ETWS, the UE can acquire the state change of the ETWS message timely by only reading the added or updated ETWS message instead of an invalid ETWS message or other system messages so as to effectively reduce the power consumption of the UE. The embodiment of the invention also discloses the user equipment and a system.

Description

technical field [0001] The present invention relates to a communication network, in particular to a method, user equipment and system for acquiring ETWS messages. Background technique [0002] Long Term Evolution (LTE) is a next-generation mobile broadband network standard formulated by the 3rd Generation Partnership Project (3GPP) standardization organization. It has high spectrum utilization and transmission speed, and low The advantages of transmission delay and so on. [0003] By carrying the earthquake and tsunami warning system (Earthquake and Tsunami Warning System, ETWS) message in the LTE system message sent to the user equipment (User Equipment, UE), the LTE system can promptly notify the user of the tsunami warning indication when an earthquake or tsunami occurs, Post-disaster rescue and other relevant information. [0004] ETWS messages are classified into Primary Notification (PN) and Secondary Notification (SN). The PN carries less content, which is mainly u...
