Embodiment Construction

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

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

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

Abstract

The invention provides a public early warning broadcasting method and system and base station equipment, and the method comprises the steps: enabling an AMF to transmit a write-in replacement early warning request message to a gNB-CU-CP through an NG interface; enabling the gNB-CU-CP to generate an F1 interface message according to the replacement indication written into the replacement early warning request message and the new public early warning information, and sending the F1 interface message to the gNB-DU, the F1 interface message comprising a replacement indication bit and the new public early warning information; and enabling the gNB-DU to replace the current public early warning broadcast information with the new public early warning information in the F1 interface message according to the replacement indication bit in the F1 interface message. Through the scheme, F1 interface signaling can be reduced, and repeated cancellation and restart of resource scheduling are avoided, so that the problems of early warning information transmission time delay and the like can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a public early warning broadcasting method, system and base station equipment. Background technique [0002] In LTE (Long Term Evolution, long-term evolution) and 5G networks, the public early warning broadcast system is mainly used to timely notify terminal users of various emergency information (such as fires, earthquakes, public safety, etc.), 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 that the 5G access network RAN ​​(Radio Access Network, wireless access network) side supports the public early warning broadcasting system mainly through the NG interface, the F1 interface and the air interface RRC (Radio Resource Control, radio resource control) SIB (System Information Block, system information block) system broadcast messa...
