Description

一种位置信息的上报方法和装置
本申请要求于2017年11月20日提交中国专利局、申请号为201711157255.9、申请名称为“一种位置信息的上报方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信技术领域，尤其涉及一种位置信息的上报方法和装置。
背景技术
在5G中为终端设备新定义了一种无线资源控制(radio resource control，RRC)去激活状态(RRC inactive state，下述可以简称inactive状态)，在该Inactive状态下，终端设备的接入层(Access Stratum，AS)上下文同时在终端设备和无线接入网(radio access network，RAN)侧保留(RAN至少包括驻留基站(Anchor gNB)，即在Anchor gNB中，终端设备从RRC连接态转移至Inactive状态时或者终端设备转移至inactive状态后，Anchor gNB也有可能将终端设备上下文传输至RAN的通知区域(RAN based notification area，RNA)内的其他的gNB进行保存)，另一方面，终端设备从Inactive状态转移至RRC连接态时，不需要重新激活RAN与核心网控制面网元(例如，接入以及移动性管理功能(access and mobility management function，AMF))的链路，例如下一代(next generation，NG)链路2。
此外，处于Inactive状态的终端设备可以在RNA内移动，当终端设备在RNA内部移动时可以不通知网络侧，这时，核心网控制面网元以及Anchor gNB可能并不知道当前时刻为终端设备提供服务的是哪个基站，因此现有技术中并未提供当核心网控制面网元需要获取终端设备的位置信息时，如何向核心网控制面网元上报终端设备的位置信息的方案。
发明内容
本发明实施例提供一种位置信息的上报方法和装置，用以提供一种当终端设备处于Inactive状态时，向核心网控制面网元及时上报终端设备的位置信息的方法。

具体实施方式
本申请中的术语“第一”、“第二”等仅是为了区分不同的对象，并不对其顺序进行限定。例如，第一基站和第二基站仅仅是为了区分不同的基站，并不对其先后顺序进行限定。
本申请中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三 种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
如图1所示，图1示出了本申请提供的一种位置信息上报的方法所应用的一种通信系统架构示意图，如图1所示，包括：5G核心网10(5G core network，5GCN)、接入网20(例如，如图1中所示的5G无线接入网(new radio access network，RAN))以及终端设备30。其中，核心网10至少包括一个或多个核心网控制面网元，例如，AMF101。接入网20至少包括两个基站，例如，基站201、基站202以及基站203。
其中，该至少两个基站中的一个基站与核心网控制面网元之间具有为终端设备30建立的控制面连接，因此可以将与核心网控制面网元之间具有为终端设备30建立的控制面连接的基站称作驻留基站(下一代基站(new radio node，gNB))，该驻留gNB保留终端设备30的上下文信息(该终端设备的上下文信息可以与RRC连接态上下文一致或者是RRC连接态上下文的一部分内容)。示例的，驻留基站可以为为终端设备30处于RRC连接态时所接入的基站，例如，图1中所示的基站201。
本申请中的接入网20形成了一个RNA，该RNA由一个小区或者多个小区组成，终端设备30可以在该RNA内移动，当RNA由多个小区组成，则这多个小区可以来自一个基站，也可以来自多个基站。此外，该RNA内还可以包括eLTE基站、5G基站以及3G基站覆盖的一个或多个小区，本申请对此不进行限定。
该至少两个基站中的一个基站为终端设备处于RRC去激活状态时为终端设备提供服务的基站，可以称为服务基站，该服务基站与终端设备存在下行同步，终端设备可以接收该服务基站发送的广播信号，并且当终端设备需要与网络侧进行信令交互时，例如终端设备在当前时刻需要发送数据，则终端设备可以通过服务基站与网络进行交互。
需要说明的是，当终端设备从RRC连接态转换为RRC去激活状态时，终端设备30可以在RNA内移动，例如，终端设备30可以从驻留gNB的覆盖范围内移动至服务基站的覆盖范围内，例如，如图1所示的，终端设备30从基站201的覆盖范围内，移动至基站202的覆盖范围内。可以理解的是，此时终端设备30依然位于RNA内，但是，由于终端设备30已进入RRC去激活状态，因此，在终端设备移动过程中，核心网和驻留gNB并不知道移动之后为终端设备30提供服务的服务基站，以及终端设备的位置信息。
当终端设备移动至RNA外时，则需要通知核心网，从而进行位置更新的操作，即RNA更新操作，该操作具体可以参考LTE中的跟踪区更新(TAU)，本申请在此不再赘述。
AMF101用于提供终端设备30的移动性管理以及接入管理的功能。
此外，该通信系统还包括演进型长期演进(evolved long term evolution，eLTE)eNB40，该eNB40可以连接到5G核心网，该eLTE eNB40可能支持RRC Inactive状 态或者类似的状态。
其中，5G核心网10和eLTE eNB40以及至少两个基站之间的接口可以为RAN-CN接口，驻留基站和服务基站之间的接口可以为Inter-BS接口，本申请对各个接口的名称不进行限定。
其中，本申请中的驻留基站和服务基站可以为能够与终端设备30进行通信的基站，可以是无线局域网(wireless local area network，WLAN)中的接入点(access point，AP)，全球移动通信系统(Global system for mobile communications，GSM)或码分多址接入(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB，NB)，还可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的基站(gNB)或者未来演进的公用陆地移动网(public land mobile network，PLMN)网络中的网络设备等。
终端设备30也可以称为终端，用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(wireless local area networks，WLAN)中的站点(station，STA)，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、可穿戴设备以及下一代通信系统，例如，第五代(fifth-generation，5G)通信网络中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端设备等。
作为示例，在本发明实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
由于终端设备从RRC连接态转换为RRC去激活态之后，并在RRC去激活态时在RNA内移动时核心网设备可能并不知道终端设备的位置信息，基于此，本申请提供一种通过第一基站接收核心网设备发送的用于指示上报终端设备的位置信息的第一消息，并根据第一消息向第二基站发送第二指示信息，以指示第二基站上报终端设备的位置信息，在这种情况下，当前时刻为终端设备服务的第二基站便可以将终端设备的位置信息及时的上报给核心网设备，或者通过第一基站向核心网设备上报终端设备的位置信息，这样便于当终端设备处于去激活状态时，核心网设备及时获取终端设备的位置信息。核心网设备获知终端设备的位置信息后，可综合终端设备的位置信息、使用流 量、网络状态等进行策略决策并发起策略更新。
本申请中的核心网设备为核心网中核心网控制面网元，例如，AMF。
基于如图1所示的架构，如图2所示，本申请提供的一种位置信息的上报方法，包括：
S101、核心网设备向第一基站发送第一消息，该第一消息用于指示获取终端设备的位置信息，其中，第一基站与核心网设备具有为终端设备建立的控制面连接。

示例性的，该第一消息可以为位置报告控制(location reporting control)消息。
可选的，第一消息包括第一指示信息，该第一指示信息用于指示上报终端设备的位置信息。
示例性的，该第一指示信息可以为请求类型request type信息，该request type信息用于指示所上报的终端设备的位置信息的类型。
其中，不同的类型所指示的获取终端设备的位置信息存在差异。
例如，终端设备的位置的类型为第一类型，第一类型用于指示上报最近一次获得到的终端设备的位置信息，终端设备的位置的类型为第二类型，第二类型用于指示上报终端设备当前时刻的位置信息。
可选的，第二类型可以为standalone。
需要说明的是，本申请以请求类型request type信息为standalone为例。
可选的，该位置报告控制消息中携带终端设备的第一标识，该终端设备的第一标识用于识别该终端设备，基于此第一标识第一基站便可以确定需要上报哪个终端设备的位置信息。
S102、第一基站接收核心网设备发送的第一消息。
S103、第一基站向第二基站发送第二消息，该第二消息包括第二指示信息，该第二指示信息用于指示上报终端设备的位置信息，该第二基站用于在当前时刻为终端设备提供服务。
示例性的，该第二基站可以为如图1所示的基站202。
可选的，该第二指示信息可以包括第一指示信息和第一指示中的至少一项，其中，第一指示为基于第一指示信息生成的，该第一指示用于指示上报终端设备的位置信息。
可以理解的是，第一指示信息也可以用于指示上报终端设备的位置信息。
本申请中第二指示信息的形式可以有多种，例如，一方面，该第二指示信息可以为第一指示信息，另一方面，该第二指示信息可以为第一指示，该第一指示基于第二指示信息生成，又一方面，该第二指示信息可以为第一指示和第一指示信息，本申请对此不进行限定。
本申请中第一基站在接收到第一消息之后，便可以开始寻呼第一标识所指示的终端设备。
本申请中第一基站可以在不同场景中向第二基站发送第二消息，不同场景下第二消息的形式可能不同，以下将结合不同场景分别介绍：
场景一、第一基站在寻呼过程中发送第二消息，则第二消息可以为寻呼消息。
可选的，该寻呼消息中还携带终端设备的标识信息以及用于指示寻呼的信息。
示例性的，终端设备的标识信息用于识别终端设备，可以为终端设备的国际识别码，也可以在RNA内唯一的标识该终端设备的标识，例如，resume ID，当然，该终端设备的标识信息还可以为上述第一标识。
场景二、第一基站在第二基站向第一基站请求终端设备的上下文过程中，通过第二消息向第二基站发送第二指示信息，此时该第二消息可以为针对请求终端设备上下文的消息(例如，获取终端设备上下文的请求消息)的回复消息，例如，该针对请求终端设备上下文的消息的回复消息可以为获取终端设备上下文的回复消息。
具体的，第二基站向第一基站请求终端设备的上下文过程可以包括：第一基站通过RNA内的基站(例如，如图1所示的基站201、基站202以及基站203)对终端设备进行寻呼，例如，第一基站在接收到第一消息后，开始向RNA内的其他基站发送寻呼消息；此时，RNA内的所有基站便向终端设备发送寻呼消息，以实现对终端设备的寻呼，然后，终端设备请求进入RRC状态的过程，具体的，可以为向服务基站发送恢复请求消息(例如，RRC连接恢复请求消息)，该恢复请求消息用于请求恢复到RRC连接态，第二基站在接收到恢复请求消息之后，向第一基站发送获取终端设备上下文的请求消息，从而进入第二基站向第一基站请求终端设备的上下文的过程。
场景三、第一基站在第二基站向第一基站请求终端设备的上下文过程后，第一基站向该服务基站发送第二指示信息，此时该第二消息可以为第一基站和第二基站之间新定义的一条信息，该新定义的消息用于请求获取终端设备当前时刻的位置信息，例如，该第一消息可以为获取终端位置请求消息、获取终端位置通知消息，本申请对该第一消息的名称不做限定。
本申请提供一种位置信息的上报方法，由于当终端设备处于去激活状态时，第一基站以及核心网设备可能并不知道当前时刻为终端设备服务的基站是哪个，也并不能及时获取到终端设备的位置信息，因此，通过第一基站接收核心网设备发送的用于指示上报终端设备的位置信息的第一消息，并根据第一消息向第二基站发送第二指示信息，以指示第二基站上报终端设备的位置信息，在这种情况下，当前时刻为终端设备服务的第二基站便可以将终端设备的位置信息及时的上报给核心网设备，或者通过第一基站向核心网设备上报终端设备的位置信息，这样便于当终端设备处于去激活状态时，核心网设备及时获取终端设备的位置信息。
需要说明的是，无论是在场景一下，还是在场景二下或者是在场景三，第一基站和第二基站均可以向核心网设备上报终端设备的位置信息，但是不同场景下，第一基站和第二基站所执行的步骤可能存在差异，因此下述将分别介绍：

终端设备的位置信息包括以下任一项：终端设备所在的跟踪区信息TAI，注册区标识，和所述终端设备当前所处小区的标识信息。
需要说明的是，在场景二和场景三下，在第一基站通过RNA内的基站寻呼终端设备的过程之后，还需要包括：

当终端设备与第二基站之间有数据传输需求时，第二基站还可以与核心网设备进行路径转换过程，在第二基站与核心网设备进行路径转换之后，该第二基站便于核心网设备之间具有终端设备的控制面连接，以使得核心网设备确定当前时刻为终端设备服务的基站为第二基站。
具体的，路径转换过程包括：
第二基站向核心网设备发送路径转换请求，该路径转换请求用于指示第二基站为终端设备的驻留基站，核心网设备向第二基站发送针对路径转换请求的回复消息。
在场景一下，可以省略第二基站向第一基站请求终端设备上下文的过程，以及省略第二基站还可以与核心网设备进行路径转换过程。
需要说明的是，在场景一下，第三消息中还需要携带终端设备的标识信息，该标识用于指示核心网设备所上报的位置信息是针对哪个终端设备的。
需要说明的是，当第一基站在寻呼过程中，也即场景一下，向第二基站发送第二指示信息时，在寻呼之后，第二基站向第一基站请求终端设备上下文的过程可以省略。
此外，在第二基站与核心网设备之间存在请求路径转换的过程时，本申请中的第三消息还可以为第二基站向核心网设备发送路径转换请求，那么在此情况下，可以省略在路径转换请求之后，第二基站向核心网设备发送终端设备的位置信息的步骤。
S105、第一基站向核心网设备发送第四消息，第四消息携带用于表明终端设备位于所述第一基站覆盖范围外的信息。
具体的，该第四消息包括第一原因值，该第一原因值用于表明终端设备位于所述第一基站覆盖范围外的信息。

S105a、核心网设备接收第一基站发送的第四消息。
基于步骤S105a核心网设备便可以确定可以从第二基站处获取到终端设备的位置信息。
此外，本申请提供的方法还包括：
S106、第二基站向终端设备发送第五消息，所述第五消息用于指示所述终端设备进入RRC连接态或者用于指示所述终端设备保持RRC去激活Inactive状态。
需要说明的是，该第五消息是第二基站在向终端设备发送寻呼消息之后，终端设备针对寻呼消息会向第二基站发送恢复请求消息，然后，该第五消息可以为针对恢复请求消息做出的响应消息。
可选的，该第五消息包括第一信息或者第二信息，其中，第一信息用于指示所述终端设备进入RRC连接态，第二信息用于指示所述终端设备保持RRC去激活Inactive状态。
示例性的，第一信息可以为RRC连接恢复消息，第二信息可以为RRC连接拒绝(RRC connection reject)消息，或者是RRC连接暂停(RRC connection suspend)消息，或者是RRC连接释放(RRC connection release)消息。
需要说明的是，在场景一下，该第五消息包括第二信息，即第二基站指示终端设备保持RRC去激活Inactive状态。
在场景二下，该第五消息包括第二信息或第一信息，即第二基站可以指示终端设备进入RRC连接态，或者也可以指示终端设备继续保持RRC去激活Inactive状态。
另一种可能的实现方式，在由第一基站向核心网设备上报终端设备的位置信息的情况下，基于图2，如图4所示，本申请提供的方法还包括：
S107、第二基站向第一基站发送第六消息，该第六消息包括终端设备的位置信息。
可选的，终端设备的位置信息包括以下至少一项：所述终端设备所在的跟踪区信息TAI，注册区标识，和所述终端设备当前所处小区的标识信息。
具体的，在场景一下，当存在第二基站向第一基站请求终端设备的上下文过程时，该第五消息可以为第二基站向第一基站请求终端设备的上下文过程中的获取终端设备上下文请求消息，该第六消息中携带终端设备的标识信息，第六消息也可以为在第二基站向第一基站请求终端设备的上下文过程中的一个新定义的信令消息，该新定义的一个信令消息中具有一个可以携带终端设备的位置信息的字段，本申请对此不进行限定。在场景一下，当第二基站向第一基站请求终端设备的上下文过程被省略时，该第六消息也可以为寻呼过程之后，第二基站和第一基站之间需要交互的一个信令消息，
在场景二和场景三下，该第六消息可以为第二基站向第一基站请求终端设备的上下文过程之后新定义的一个信令消息或者已有的一个信令消息，该信令消息中具有用于携带终端设备的位置信息的字段。
S108、第一基站接收第二基站发送的第六消息，第六消息携带终端设备的位置信息。
具体的，第一基站接收第五消息是哪种形式，具体可以参见上述实施例中，第五消息是在哪个过程中发送的，本申请对此不进行限定。

可以理解的是，如图4所示，在由第一基站向核心网设备上报终端设备的位置信息的情况下，本申请提供的方法依然可以包括步骤S106。
又一种可能的实现方式，可能存在第一基站和第二基站均无法寻呼到终端设备，那么基于图2，本申请提供的方法还包括：

综上所述，下述图5以驻留基站在服务基站请求终端设备的上下文过程中向服务基站发送第二指示信息以及由服务基站向AMF上报终端设备的位置信息的过程为例，具体的，如图5所示，图5示出了本申请提供的一种位置信息上报方法的具体流程，包括：
S201、AMF向驻留基站发送位置报告控制(location reporting control)消息，该位置报告控制消息包括request type信息。
其中，request type信息用于指示获取终端设备的位置信息。
可选的，该request type信息指示位置报告的类型为standalone。
可以理解的是，位置报告的类型不同指示驻留基站所获取的终端设备的位置信息不同，例如，位置报告的类型为standalone时，用于指示获取终端设备当前的位置信息。例如，当位置报告的类型为除standalone之外的其他类型时，用于指示驻留基站上报驻留基站最近一次获取到的终端设备的位置信息。
可选的，该位置报告控制消息中携带终端设备的第一标识，该终端设备的第一标识用于识别终端设备。
S202a、驻留基站接收核心网设备发送的位置报告控制消息。
S202、驻留基站向RNA内除驻留基站之外的其他基站发送寻呼(paging)消息，该paging消息携带终端设备的第二标识，以及用于指示寻呼终端设备的信息。
需要说明的是，驻留基站在接收到位置报告控制消息后，便发起寻呼流程，以寻呼终端设备。
可选的，该RNA内至少包括终端设备从RRC连接态转换为RRC去激活状态时，当前时刻为终端设备提供服务的服务基站，例如，图2中所示的基站202。
可以理解的是，终端设备当前时刻已位于驻留基站的范围外，且位于为终端设备提供服务的服务基站的范围内。
示例的，该第二标识可以在RNA内唯一的标识该终端设备，例如该第二标识可以 为resume ID。
可以理解的是，第一标识和第二标识可以相同。
S203、驻留基站以及其他收到驻留基站发送的paging消息的基站(例如，服务基站)向终端设备发送paging消息。
S204、终端设备收到paging消息以后向服务基站发送恢复请求消息，该恢复请求消息可以用于请求恢复到连接(connected)状态。
示例性的，恢复请求消息可以为RRC连接恢复请求消息。
可选的，该RRC连接恢复请求消息还可以携带驻留基站的标识信息，这样服务基站便可以根据驻留基站的标识信息确定驻留基站，以便从驻留基站处请求获取终端设备的上下文。
S205、服务基站向驻留基站发送第一请求消息，该第一请求消息携带终端设备的第一标识信息，该第一请求消息用于获取终端设备的上下文。
例如，该第一请求消息可以为获取终端设备上下文请求消息。
可选的，该第一标识信息可以为终端设备的第一标识或者第二标识，或者其他标识，本申请对此不进行限定，只要该第一标识信息可以标识终端设备即可。
S206、驻留基站向服务基站发送针对第一请求消息的第一回复消息，该第一回复消息至少包括终端设备的上下文信息以及第二指示信息，该第二指示信息用于指示上报终端设备的位置信息。
需要说明的是，通过第一请求消息驻留基站便可以确定当前时刻为终端设备服务的基站为服务基站。
可选的，该第二指示信息可以包括第一指示和第一指示信息中的至少一项，其中，第一指示为基于第一指示信息生成的，该第一指示用于指示上报终端设备的位置信息。
本申请中第二指示信息的形式可以有多种，例如，一方面，该第二指示信息可以为第一指示，另一方面，该第二指示信息可以为第一指示信息，该第一指示基于第一指示信息生成的，又一方面，该第二指示信息可以为第一指示信息和第一指示，本申请对此不进行限定，其中，第一指示信息可以为request type信息。
示例性的，第一回复消息可以为获取终端设备上下文回复消息。
可选的，第一回复消息包括终端设备的第一标识信息，终端设备的上下文信息包括RRC配置信息、安全信息、会话或者流的QoS信息等。
S207、服务基站向终端设备发送针对恢复请求消息的第二回复消息，该第二回复消息中携带用于指示终端设备进入RRC连接状态的信息，或者携带用于指示终端设备保持当前状态(也可以为继续停留在当前状态，即保持inactive状态)的信息。
可选的，该第二回复消息可以包括第三消息或第四消息，其中，第三消息用于指示终端设备进入RRC连接状态，第四消息用于指示终端设备保持当前状态。
示例性的，第三消息可以为RRC连接恢复消息，第四消息可以为RRC连接拒绝(RRC connection reject)消息，或者RRC连接暂停(RRC connection suspend)消息，或RRC连接释放(RRC connection release)消息。
在终端设备接收到第三消息后，终端设备进入RRC连接状态，或者在终端设备接收到第四消息后，终端设备保持当前状态。
S208、服务基站向AMF发送路径转换请求(path switch request)。
S209、AMF向服务基站发送路径转换响应(path switch request Ack)。
可以理解的是，经过步骤S208和S209之后，AMF便可以确认为终端设备服务的基站为服务基站，也即AMF后续可以通过服务基站与该终端设备通信。
S210、服务基站向驻留基站发送第二请求消息，该第二请求消息携带用于指示释放终端设备上下文的信息。
其中，该第二请求消息的形式可以有多种，例如，该第二请求消息可以为终端设备上下文释放消息，也可以为新定义的其他信令消息，也可以为现有的信令消息，该现有的信令消息中携带用于指示释放终端设备上下文的信息，本申请对此不进行限定。
S211、驻留基站接收到收到终端设备上下文释放消息后，驻留基站释放终端设备的上下文。
S212、服务基站向AMF发送location report，该location report中包括终端设备的位置信息。
S212a、核心网设备接收服务基站发送的location report。
基于步骤S212a核心网设备便可以确定终端设备的位置信息。
需要说明的是，由于在步骤S208和S209中AMF和服务基站进行了路径转换，因此步骤S212中的Location Report可以不携带终端设备的标识信息，这样可以减少信令开销。当然，也可以携带终端设备的位置信息。
此外，进一步的，服务基站也可以在路径转换请求中携带终端设备的位置信息，在这种情况下，步骤S212则可以省略。
S213、驻留基站向AMF发送位置报告失败(location report failure)消息，该位置报告失败消息携带用于指示终端设备位于驻留基站的覆盖范围外的信息。
具体的，用于指示终端设备位于驻留基站的覆盖范围外的信息可以为第一原因指示值，该第一原因指示值用于指示终端设备位于驻留基站的覆盖范围外。
可选的，该第一原因指示值还用于指示当前时刻为终端设备提供服务的基站为服务基站，或者向AMF指示上报终端设备位置信息的基站为服务基站，这样AMF在接收到该位置报告失败消息后便可以等待服务基站上报终端设备的位置信息，以从服务基站处获取终端设备的位置信息。
S213a、核心网设备接收驻留基站发送的位置报告失败消息。
此外，本申请中当服务基站和核心网设备之间存在路径转换过程时，即图5中的步骤S208和S209时，在由服务基站向核心网设备上报终端设备的位置信息的场景下，步骤S212可以省略，此时，服务基站可以在S208中的路径转换请求中携带终端设备的位置信息，以使得核心网设备在路径转换过程中便可以确定终端设备的位置信息。
需要说明的是，本申请中并不限定步骤S201-S213的先后顺序，此外，步骤S206-S212与步骤S213可以并行执行，本申请对此不进行限定，也即在驻留基站指示服务基站上报终端设备的位置信息过程中，驻留基站便可以通知AMF可以等待服务基站上报终端设备的位置信息。
此外，图5所示的方案，驻留基站通过将第二指示信息针对当前时刻为终端设备服务的服务基站发送，可以避免在驻留基站不确定为终端设备服务的服务基站的情况 下，向RNA内所有的基站发送第二指示信息所引起的信令开销大的问题。
如图6所示，图6以驻留基站在通过RNA内所有的基站寻呼终端设备的过程中向驻留基站发送第二指示信息，以及由服务基站上报终端设备的位置信息为例，图6示出了本申请提供的一种位置信息上报方法的具体流程，图6所示的方法与图5的区别在于：
一方面，图5中第二指示信息携带在驻留基站针对第一请求消息的第一回复消息中，即驻留基站在对服务基站发送的请求终端设备的上下文的回复消息中携带第二指示信息，而图6中第二指示信息携带在驻留基站发送给RNA内的所有基站的paging消息中，即驻留基站通过RNA内所有基站寻呼终端设备的过程中在寻呼消息发送第二指示信息，也即步骤S202中除了携带用于指示寻呼的信息、终端设备的第一标识之外，还携带第二指示信息。这样服务基站在接收到寻呼消息之后，便可以根据第二指示信息确定需要上报终端设备的位置信息，从而向核心网设备上报终端设备的位置信息，也即服务基站可以在寻呼过程中确定需要上报终端设备的位置信息。
另一方面，图6中可以不包括服务基站向驻留基站请求终端设备的上下文过程，也即图6所示的方案中可以不包括上述步骤S205和S206，此外，步骤S207中的第二回复消息可以不携带用于指示终端设备进入RRC连接态的信息，此时，第二回复消息中携带用于指示终端设备继续停留在RRC去激活状态的信息，这样终端设备在接收到第二回复消息之后，继续停留在RRC去激活状态。
又一方面，图6中可以不包括服务基站向AMF请求路径转换的过程，也即图6所示的方案可以不包括上述步骤S208和S209，以及服务基站请求驻留基站释放终端设备的上下文过程，例如，图6所示的方案可以不包括上述步骤S210和步骤S211。
再一方面，在图6所示的方案中，由于服务基站未向AMF请求路径转换，因此，为了使得AMF可以确定步骤S212中发送的location report是针对哪个终端设备的，服务基站向核心网设备发送的location report中还需要携带终端设备的第二标识信息，该终端设备的第二标识信息用于识别该终端设备。
例如，该第二标识信息可以为NAS标识信息，例如国际移动用户识别码(international mobile subscriber identification number，IMSI)，临时移动用户识别码(temperateMobile subs cription identity，TMSI)等标识信息。
综上所述，图6所示的方案通过将第二指示信息携带在寻呼消息中，可以使得服务基站在寻呼过程中确定需要上报终端设备的位置信息，因此可以使得AMF提前获取终端设备的位置信息，此外，由于图6所示的方案中可以不执行获取终端设备上下文的过程，从而减少了信令开销。
需要说明的是，图5和图6所示的方案是由服务基站向AMF上报终端设备的位置信息，由于在AMF请求上报终端设备位置信息的过程中，服务基站的AMF可能会因为某种原因从与驻留基站具有相同的AMF(例如，第一AMF，即为需要获取终端设备的位置信息的AMF)更换为与驻留基站不同的AMF(例如，第二AMF)，因此，为了使得第一AMF可以及时的获取到终端设备的位置信息，服务基站可以先向第二AMF发送终端设备的位置信息，然后由第二AMF将终端设备的位置信息发送给第一AMF，其中，服务基站在向第二AMF发送终端设备的位置信息时，还可以携带一个 第三指示信息，该第三指示信息用于指示将终端设备的位置信息发送给第一AMF，此外，服务基站也首先需要确定是第一AMF需要获取终端设备的位置信息。
更进一步的，图5所示的方案中由于将第二指示信息仅针对RNA内为终端设备当前时刻服务的基站(例如，服务基站)发送，因此相比于图6所示的方案需要向RNA内所有的基站发送寻呼消息中携带第二指示信息相比可以减少信令开销。
图7所示的方案以由驻留基站向AMF上报终端设备的位置信息以及在通过RNA内所有基站寻呼终端设备的过程中向终端设备发送第二指示信息为例，因此，图7所示的方案，包括：
S301、AMF向驻留基站发送位置报告控制(location reporting control)消息，该位置报告控制消息包括request type信息。
其中，位置报告控制消息的具体内容可以参见上述实施例，本申请在此不再赘述。
S302a、驻留基站接收位置报告控制消息。
S302、驻留基站向RNA内除驻留基站之外的其他基站发送RAN paging消息，该paging消息携带终端设备的第二标识，以及第二指示信息。
具体的，第二指示信息的内容可以参见上述实施例中的描述，本申请在此不再赘述。
可选的，该RNA内至少包括终端设备在RRC连接态时所接入的驻留基站，以及终端设备从RRC连接态转换为RRC去激活状态时，当前时刻为终端设备提供服务的服务基站。
可以理解的是，终端设备当前时刻已位于驻留基站的范围外，且位于为终端设备提供服务的服务基站的范围内。
示例的，该第二标识可以在RNA内唯一的标识该终端设备，例如该第二标识可以为resume ID。
可以理解的是，第一标识和第二标识可以相同。
S303、驻留基站以及其他收到驻留基站发送的paging消息的基站(例如，服务基站)向终端设备发送paging消息。
S304、终端设备收到paging消息以后向服务基站发送恢复请求消息，该恢复请求消息可以用于请求终端设备恢复到连接(connected)状态。
S305、服务基站向驻留基站发送第一请求消息，该第一请求消息携带用于获取终端设备的上下文的信息、用于确定终端设备位置信息的信息以及终端设备的第一标识信息。
例如，该第一请求消息可以为获取终端设备上下文请求消息，用于确定终端设备位置信息的信息可以包括：终端设备当前所处的小区的标识信息。
需要说明的是，当第一请求消息为获取终端设备上下文请求消息时，用于确定终端设备位置信息的信息还可以包括：终端设备当前所处的跟踪区标识(tracking area identity，TAI)或者注册区标识(registration area identity，RAI)。
示例性的，终端设备当前所处的小区的标识信息可以为终端设备当前所处的小区的全球标识(cell global identity)或者是终端设备当前所处的小区的物理小区标识(PCI，physical cell identity)，也可以是其他的标识形式，本申请对此不进行限定。
S306、驻留基站向服务基站发送针对第一请求消息的第一回复消息，该第一回复消息携带终端设备的上下文信息。
具体的，终端设备的上下文信息可以参见上述实施例，本申请在此不再赘述。
S307、服务基站向终端设备发送针对恢复请求消息的第二回复消息，该第二回复消息中携带用于指示终端设备保持当前状态(也可以为继续停留在当前状态，即保持inactive状态)的信息。
可选的，该第二回复消息可以包括第四消息，该第四消息用于指示终端设备保持当前状态。
示例性的，第四消息可以为RRC连接拒绝(RRC connection reject)消息，或者RRC连接暂停(RRC connection suspend)消息，或RRC连接释放(RRC connection release)消息。此外，在终端设备接收到第四消息后，终端设备保持当前状态。
S308、服务基站向AMF发送路径转换请求(path switch request)。
S309、AMF向服务基站发送路径转换响应(path switch request Ack)。
可以理解的是，经过步骤S308和S309之后，AMF便可以确认为终端设备服务的基站为服务基站，也即AMF后续可以通过服务基站与该终端设备通信。
S310、服务基站向驻留基站发送第二请求消息，该第二请求消息携带用于指示释放终端设备上下文的信息。
其中，该第二请求消息的形式可以有多种，例如，该第二请求消息可以为终端设备上下文释放消息，也可以为新定义的其他信令消息，也可以为现有的信令消息，该现有的信令消息中携带用于指示释放终端设备上下文的信息，本申请对此不进行限定。
S311、驻留基站接收到收到第二请求消息后，驻留基站释放终端设备的上下文。
S312、驻留基站向AMF发送location report，该location report中包括终端设备的位置信息。
S312a、AMF接收驻留基站发送的location report。
综上所述，图7所示的方案，与图5所示的方案的区别在于，图7中由驻留基站向AMF上报终端设备的位置信息，由于在由服务基站上报终端设备位置信息的场景下，服务基站通常会将终端设备的位置信息上报给自己所在的AMF，而服务基站在获取到第二指示信息的过程中有可能会因为某种原因更换AMF，在更换后的AMF与需要获取终端设备的位置信息的AMF不一致的情况下，若继续由服务基站上报终端设备位置信息便会出现如下问题：需要获取终端设备的位置信息AMF无法获取终端设备的位置信息，因此，在由驻留基站向AMF上报终端设备的位置信息可以避免上述问题，此外，驻留基站将第二指示信息在寻呼过程发送给RNA内的其他基站，这样可以便于AMF提前获取终端设备的位置信息，进一步的，由于进行了路径转换，便可以使得AMF在后续过程中通过服务基站与终端设备通信。

S409、服务基站向AMF发送路径转换请求(path switch request)。
S410、AMF向服务基站发送路径转换响应(path switch request Ack)。

基于图8所示的方案，针对场景三，本申请提供了一种位置信息的上报方法，该图9所示的方案与图8所示的方案的区别在于，图8中驻留基站在服务基站向驻留基站请求终端设备的上下文过程中，也即在步骤S406的第一回复消息中携带第二指示信息，而在图9所示的方案中是在驻留基站在服务基站向驻留基站请求终端设备的上下文过程之后，由驻留基站向服务基站发送获取终端位置通知消息，如图9所示的步骤S415，该获取终端位置通知消息用于上报终端设备的位置信息，可选的，该获取终端位置通知消息中携带第二指示信息，此外，服务基站可以基于该获取终端位置通知消息向驻留基站发送获取终端位置响应消息，该获取终端位置响应消息中携带终端设备的位置信息，基于获取终端位置响应消息驻留基站便可以确定终端设备的位置信息。
需要说明的是，在服务基站向驻留基站请求上下文过程之后的场景中，本申请中的驻留基站均可以向服务基站发送用于获取终端位置信息的消息，基于该用于获取终端位置信息的消息服务基站便可以向驻留基站上报终端设备的位置信息。
基于图7所示的方案，图10所示的方案以由驻留基站向AMF上报终端设备的位置信息，以及驻留基站在通过RNA内所有基站寻呼终端设备的过程中发送第二指示信息为例，图10所示的方案与图7所示的方案的区别在于：
