终端定位方法、装置及网络侧设备
相关申请的交叉引用
本申请要求在2021年11月30日提交的中国专利申请第202111453507.9号的优先权,该中国专利申请的全部内容通过引用包含于此。
技术领域
本申请属于移动通信技术领域,具体涉及一种终端定位方法、装置及网络侧设备。
背景技术
相关技术在执行对终端(也称为用户设备(User Equipment,UE))的定位业务时,核心网设备,例如接入和移动管理功能(Access and Mobility Management Function,AMF)可以从第三方设备、终端或自身接收到针对该终端的定位业务请求。如果UE此时处于无线资源控制(Radio Resource Control,RRC)空闲(Idle)态,则其与核心网络设备的连接管理状态(Connection Management state,CM state)为连接管理空闲(CM-IDLE)态,核心网设备可通过寻呼该UE以触发UE进入连接管理连接(CM-CONNECTED)态,此时,UE的RRC连接状态是RRC连接态,然后核心网设备向定位服务器,即本地管理功能(Location Management Function,LMF)发送定位业务请求,由LMF发起具体的定位过程以获取到UE的位置。其中,LMF可能需要基于与终端之间的LTE定位协议(LTE Positioning Protocol,LPP)与终端进行交互,还可能需要基于与接入网设备,即基站之间的定位协议,例如新空口定位协议A(NR Positioning Protocol A,NRPPa)协议与接入网设备进行交互。
然而,当UE处于RRC去激活(RRC-inactive)态时,由于UE的CM state为CM-CONNECTED,因此,核心网设备不会触发终端进入RRC连接态。当向终端发送的定位协议消息传递给核心网设备时,核心网设备将其放在一个非接入层(Non-access Stratums,NAS)消息中发送给UE的锚点基站,所述锚点基站是保存该终端的RRC上下文的基站,比如,可以为UE从连接态转化为非激活态前处在的基站,但是该锚点基站由于UE在RRC去激活态,可能无法将NAS消息发送给UE,然后向核心网设备发送NAS消息递送失败消息(NAS Non Delivery Indication),核心网设备将丢弃掉该消息。定位服务器在长时间未收到响应消息后决定重传,从而造成定位时延长,不满足定位 的服务质量(Quality of Service,QoS),或者直接导致定位失败。
