Embodiment Construction

[0030] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0031] In the current public warning information processing, the NG interface message sent by the AMF to the gNB-CU-CP provides a public warning information concurrent indication (Concurrent Warning Message Indicator). The warning message is a newly added public warning message, otherwise, if the concurrent indication does not appear, the warning message needs to be used to replace the existing public warning message being broadcast.

[0032] Under the existing protocol framework, when the gNB-CU-CP receives the public warning information broadcast r...

Abstract

The present invention provides a public early warning broadcasting method, system and base station equipment, wherein the method includes: making the AMF send a write replacement early warning request message to the gNB-CU-CP through the NG interface; making the gNB-CU-CP according to the writing The replacement instruction and the new public early warning information in the replacement early warning request message generate an F1 interface message, and send the F1 interface message to the gNB-DU, wherein the F1 interface message includes the replacement indication bit and the new public early warning information; make the gNB-DU according to The replacement indication bit in the F1 interface message replaces the current public early warning broadcast information with the new public early warning information in the F1 interface message. Through the above solution, F1 interface signaling can be reduced, and repeated cancellation and restart of resource scheduling can be avoided, so that problems such as transmission delay of early warning information can be alleviated.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a public early warning broadcasting method, system and base station equipment. Background technique [0002] In LTE (Long Term Evolution) and 5G networks, the public early warning broadcasting system is mainly used to notify end users of various emergency information (such as fire, earthquake, public safety, etc.) in a timely manner, so that users can immediately Take effective measures to deal with it. [0003] Currently 3GPP (3 rd The Generation Partnership Project (3rd Generation Partnership Project) defines the RAN (Radio Access Network, Radio Access Network) side of the 5G access network to support the public early warning broadcasting system mainly through the NG interface and the F1 interface and the air interface RRC (Radio Resource Control, radio resource control) SIB (System Information Block, system information block) system broadcast message t...
