Problems solved by technology

However, the UE will not actively receive SIB1 that does not carry ETWS messages
Therefore, if the UE does not receive the ETWS message completely, it will always monitor the ETWS message, that is, the UE is always in a state of power consumption

Abstract

Embodiments of the present invention provide an information transmission method, base station, and user equipment (UE). The method comprises: after the broadcast of an Earthquake and Tsunami Warning System (ETWS) message is finished, generating a paging message; and broadcasting the paging message, the paging message being used for instructing a UE in an ETWS message monitoring state to receive a system information block, and the system information block not carrying scheduling and mapping information of an ETWS primary notification message PN and an ETWS secondary notification message SN. In the embodiment of the present invention, the UE receives a paging message broadcasted by the base station, and actively receives a system information block that does not carry scheduling and mapping information of an ETWS primary notification message PN and an ETWS secondary notification message SN, so that the UE stops monitoring the ETWS message, thereby effectively reducing the power consumption of the UE.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and more specifically, relate to an information transmission method, a base station, and user equipment. Background technique [0002] E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) receives the ETWS (Earthquake and Tsunami Warning System, Earthquake and Tsunami Warning System) alarm sent by MME (Mobility Management Entity, mobility management network element) After sending the request (Write-Replace Warning Request) message, the base station broadcasts the SIB1 (System Information Block1, system information block 1) carrying the ETWS message to the UE (User Equipment, user equipment). [0003] After the broadcast of the ETWS message ends, the base station will remove the scheduling mapping information of the ETWS message from the SIB1 message. However, the UE will not actively receive the SIB1 that ...
