在双连接或多连接操作中,一旦用户设备(UE,User Equipment)在主节点(MN,Master Node)/主服务小区组(MCG,Master Cell Group)侧遇到主无线链路故障(P-RLF,Primary Radio Link Failure),UE就可以通过辅节点(SN,Secondary Node)/辅服务小区组(SCG,Secondary Cell Group)侧的信令无线承载(SRB,Signaling Radio Bearer)3执行主无线链路故障(P-RLF,Primary Radio Link Failure)的快速恢复,然后SN通过Xn接口进行Xn接口应用流程协议(XnAp,Xn Application Protocol)过程,或通过X2接口进行X2接口应用流程协议(X2AP,Xn Application Protocol)过程,以与MN进一步协调和交互,并且MN将进一步通过SRB3进行RRC重配置,而不是作为传统方式的通过SRB1进行RRC重建。主无线链路故障的快速恢复取决于以下至少之一:SN/SCG侧的SRB3是否支持主无线链路故障的快速恢复的能力;SN/SCG侧的SRB3是否支持主无线链路故障的快速恢复的状态;而相关技术中MN/MCG侧无法获知该信息,从而可能发生错误配置,进而导致主无线链路故障的快速恢复的成功率较低。

除非另外限定,否则本文所用的所有术语(包括技术和科学术语)的含义与本领域普通技术人员通常理解的含义相同。还将理解,诸如那些在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开的背景下的含义一致的含义,且将不解释为具有理想化或过度形式上的含义,除非本文明确如此限定。
如图1所示,第三代合作伙伴项目(3GPP,The 3rd Generation Partnership Project)专用第五代移动通信(5G,Fifth Generation)蜂窝网络主要包括5G核心网(5GC,5G Core)(如接入移动功能(AMF,Access Mobility Function)、会话管理功能(SMF,Session Management Function)、用户面功能(UPF,User Plane Function)等)和5G无线接入网(NG-RAN,Next Generation-Radio Access Network)节点,5GC和NG-RAN节点通过NG接口连接(3GPP标准化,参见TS38.413)。其中,NG-RAN节点包括至少两种类型的无线接入技术(RAT,Radio Access Technology)节点:gNB(NR)和ng-eNB(演进的通用移动通讯系统(UMTS,Universal Mobile Telecommunications System)陆地无线接入(E-UTRA,Evolved-UMTS Terrestrial Radio Access)),RAT节点通过Xn接口连接(3GPP标准化,参 见TS38.423)。相似的,3GPP专用第四代移动通信(4G,Forth Generation)蜂窝网络主要包括演进的分组核心网(EPC,Evolved Packet Core)(如移动管理实体(MME,Mobility Management)、服务网关(SGW,Serving Gateway)等)和RAN节点,EPC和RAN节点通过S1接口连接(3GPP标准化,参见TS36.413)。RAN节点包括单一类型的RAT节点:eNB(E-UTRA),eNB间通过X2接口连接(3GPP标准化,参见TS36.423)。
在5G单连接操作中,用户设备(UE,User Equipment)连接到单个NG-RAN节点或由单个NG-RAN节点提供服务,并且注册至锚点5GC实体。处于单连接操作中的UE可能遇到无线链路故障,也就是说,由于本地无线条件差,MN/MCG侧发生无线链路故障(RLF,Radio Link Failure)。当MN/MCG侧发生RLF时,UE将通过SRB0进行无线资源控制(RRC,Radio Resource Control)重建过程,以恢复服务无线链路,并继续数据传输;在RRC重建过程失败的情况下,UE将回退到空闲模式。
如图2所示,在多连接或双连接操作中(3GPP标准化,参见TS37.340),UE同时连接到多于一个NG-RAN节点,或同时由多于一个NG-RAN节点提供服务,也就是说,至少一个MN加上至少一个辅节点(SN,Secondary Node)共同为UE提供服务。在Uu空口(3GPP标准化,参见TS38.331和TS36.331)中,MN向UE提供用于主无线链路的MCG配置和资源,而SN向UE提供用于辅无线链路的辅服务小区组(SCG,Secondary Cell Group)配置和资源。在主无线链路上,下行链路(DL,Downlink)或上行链路(UL,Uplink)的用户数据经由数据无线承载(DRB,Data Radio Bearer)传输,DL/UL的信令数据通过SRB0、SRB1和SRB2传送。在辅无线链路上,DL/UL的用户数据也通过另一组DRB传送,DL/UL的信令数据通过SRB3传送,该SRB3与SRB0/1/2不同,且具有不同的配置和资源,并且SN/SCG侧没有SRB0/1/2。
与单连接情况类似,由于本地无线电条件不佳,双连接或多连接操作中的UE可能遇到主无线链路故障,即MN/MCG侧的P-RLF,那么,当发生P-RLF时,UE通常会通过MN/MCG侧的SRB0执行RRC重建过程, 以恢复主无线链路及其MCG配置和资源,从而继续双连接或多连接中的数据传输。
作为Rel-16的增强功能,通过MN/SN的特殊使能或配置或激活,UE也可以通过SN/SCG侧的SRB3执行RRC重建过程,以用于主无线链路故障的快速恢复(Fast MCG Recovery),只要SRB3仍然工作并且处于比SRB0更好的无线条件,并且主无线链路故障的快速恢复提供比基于传统SRB0的恢复更短的恢复延迟和更高的鲁棒性。
例如,如图3所示,在双连接操作中,一旦UE在MN/MCG侧遇到P-RLF,UE就可以通过SN/SCG侧的SRB3执行主无线链路故障的快速恢复,然后SN通过Xn接口进行XnAp过程,或通过X2接口进行X2AP过程,以与MN进一步协调和交互,并且MN将进一步通过SRB3进行RRC重配置,而不是作为传统方式的通过SRB1进行RRC重建。主无线链路故障的快速恢复取决于以下至少之一:SN/SCG侧的SRB3是否支持主无线链路故障的快速恢复的能力;SN/SCG侧的SRB3是否支持主无线链路故障的快速恢复的状态;而相关技术中MN/MCG侧无法获知该信息,从而可能发生错误配置,进而导致主无线链路故障的快速恢复的成功率较低。
