Description

一种链路失败处理方法、装置、设备及存储介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种链路失败处理方法、装置、设备及存储介质。
背景技术
为了运营商能够更好的进行网络优化,引入了最小路测机制(Minimum Drive Test,MDT)。当用户设备(User Equipment,UE)出现链路失败时,链路失败的原因可能是无线链路失败或者切换失败,UE可以记录相应的失败信息。当UE恢复与基站的连接之后,可以将记录的失败信息上报给基站,基站基于失败信息可以进一步进行网络优化。新空口(new radio,NR)系统中,终端和基站之间的通信接口可以称为Uu接口。
为了支持UE与UE之间的直接通信,引入了侧行链接(Sidelink)通信方式。UE只存储Uu接口的失败信息,不会存储Sidelink上的失败信息,从而运营商无法针对Sidelink进行优化。

如图1所示,本公开实施例提供的发链路失败处理方法可应用于无线通信系统100,该无线通信系统可以包括用户设备101以及网络设备102。其中,用户设备101被配置为支持载波聚合,用户设备101可连接至网络设备102的多个载波单元,包括一个主载波单元以及一个或多个辅载波单元。
应理解,以上无线通信系统100既可适用于低频场景,也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access,WiMAX)通信系统、云无线接入网络(cloud radio access network,CRAN)系统、未来的第五代(5th-Generation,5G)系统、新无线(new radio,NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network,PLMN)系统等。
以上所示用户设备101可以是用户设备(user equipment,UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station,MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备101可具备 无线收发功能,其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信),并接受网络设备102提供的网络服务,这里的网络设备包括但不限于图示基站。
其中,用户设备101可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理personal digital assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中,接入网设备是指有提供网络接入功能的设备,如无线接入网(radio access network,RAN)基站等等。网络设备具体可包括基站(base station,BS)设备,或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备可以是可穿戴设备或车载设备。网络设备也可以是具有通信模块的通信芯片。
