Problems solved by technology

[0003] In the LTE system, since the system information is usually sent by broadcast, the base station (eNB of the LTE system) does not know which system information the UE is interested in, so the target base station will only send the access target cell to the UE in the handover command The required information, while other system messages need to be obtained after the UE and the target base station are synchronized, which needs to introduce additional delay (the UE waits for new system messages in the target cell) or signaling (the base station sends a message to the UE through dedicated signaling) system information)

Abstract

The embodiment of the invention provides a system message sending method and device and a system message receiving method and device. According to the embodiment of the invention, in the switching process; a target base station can receive indication information of a system message sent by a source base station, therefore, the target base station can quickly send the related system message in theswitching process or after the switching is finished; in addition, according to the embodiment of the invention, the signaling message in the existing switching process can be used for sending the related system message, so that the signaling overhead for sending the system message can be saved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a system message sending method, receiving method and equipment. Background technique [0002] In terms of sending system messages, 5G introduces an on-demand system message sending method, that is, some system message base stations (gNB, RAN node of the 5G new air interface system) may not broadcast and send, and the terminal (UE) actively Request to gNB and then send to UE by broadcast or unicast. [0003] In the LTE system, since the system information is usually sent by broadcast, the base station (eNB of the LTE system) does not know which system information the UE is interested in, so the target base station will only send the access target cell to the UE in the handover command The required information, while other system messages need to be obtained after the UE and the target base station are synchronized, which needs to introduce additional delay (...
