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

The embodiment of the invention provides an information transmission method, a base station and user equipment (UE). The method comprises the following steps of: after an earthquake and tsunami warning system (ETWS) finishes message broadcast, generating a paging message; and broadcasting the paging message, wherein the paging message is used for instructing the UE which is in a state of monitoring an ETWS message to receive a system message block, and the system message block does not carry the scheduling mapping information of an ETWS primary notification message (PN) and an ETWS secondary notification message (SN). According to the embodiment of the invention, the UE receives the paging message which is broadcasted by the base station, and actively receives the system message block which does not carry the scheduling mapping information of the ETWS PN and the ETWS SN, so that the UE can stop monitoring the ETWS message, and power consumption of the UE is effectively reduced.

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 ...
