Description

一种确定寻呼区域的方法、接入网节点及核心网节点
相关申请的交叉引用
本申请主张在2016年10月11日在中国提交的中国专利申请号No.201610887826.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种确定寻呼区域的方法、接入网节点及核心网节点。
背景技术
如图1所示，新一代(NextGen)网络的架构主要由用户设备(User Equipment，UE，也可以称之为终端)、无线接入网(RAN)节点和新一代核心网络(NextGen Core Network)组成。其中，NextGen Core Network由控制平面功能(CP functions)和用户平面功能(UP functions)构成，UE通过NG1接口与CP functions连接，RAN节点通过NG2接口与CP functions连接，通过NG3接口与UP functions连接，CP functions与UP functions通过NG4接口连接，且CP functions通过NG5接口与应用服务功能(AF)连接，UP functions通过NG6接口与数据网络(DN)连接。
TR 23.799中引入了一种新的移动性状态无线资源控制(RRC)不活跃连接(RRC_inactive_connected)状态，当UE在该状态下时，RAN节点虽然释放了该UE的RRC连接，但仍然保留UE的NG2和NG3接口的连接。
UE在该状态对核心网透明，即核心网仍然认为UE一直处于连接态，因此下行信令或数据将会到达RAN节点，此时RAN节点需要寻呼UE。
如图2所示，在TR 23.799中一种确定无线接入网级别(RAN level)寻呼区域的方法为：
步骤1，UE在服务请求(Service Request)消息中携带UE期望长期驻留的区域信息；
步骤2，NG Core(新一代核心网)根据UE的期望、UE的签约和网络的配置确定预期区域(intended area)，然后在使用用户面的过程中，NG Core和RAN协商UE允许以RRC_inactive_connected状态长期驻留的区域，然后 NG Core将协商后的区域确定为长连接允许区域(Long Connected Allowed Area)，并通知给UE；
步骤3，UE进入RRC inactive模式；
步骤4，当UE移出了Long Connected Allowed Area时，UE通知NG Core，以更新或删除Long Connected Allowed Area。
需要说明的是，相关技术中，当UE移出当前的RAN level的寻呼区域后，无法进行该寻呼区域的更新或重分配，进而影响了网络的通信。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
本公开针对相关技术中并没有当UE移出当前的RAN level的寻呼区域后，进行该寻呼区域的更新或重分配的方案，从而影响网络通信的问题，提供一种确定寻呼区域的方法、接入网节点及核心网节点。
在一些实施例中，如图3所示，本公开实施例提供一种确定寻呼区域的方法，应用于接入网节点，包括以下步骤。
步骤31，获取为终端进行寻呼区域分配的指示信息；
需要说明的是，该方法主要是确定终端在RRC不活跃状态(即背景技术中所说的RRC_inactive_connected状态)下的无线接入网级别的寻呼区域，该指示信息可以为核心网节点发送给接入网节点的，也可以是终端直接发送给接入网节点的，同时需要说明的是，当终端未进入RRC不活跃状态时，该指示信息用来指示为终端进行寻呼区域分配，而当终端已经处于RRC不活跃状态时，该指示信息用来指示为终端进行寻呼区域的重新分配(即此时进行的是寻呼区域的更新)。
步骤32，根据所述指示信息，为终端确定寻呼区域；本步骤中，当接入网节点接收到指示信息时，会根据该指示信息为终端确定无线接入网级别的寻呼区域。
步骤33，将所述寻呼区域通知给所述终端。
需要说明的是，本实施例中的接入网节点指的是当前为终端服务的接入网节点。
本公开实施例通过根据为终端进行寻呼区域分配的指示信息，确定终端的寻呼区域，实现了终端在RRC不活跃状态下的无线接入网级别的寻呼区域的确定，保证了网络通信的完整性。
需要说明的是，接入网节点可以在终端附着到网络或发起位置更新过程或在发起服务请求过程中控制终端进入RRC不活跃状态，并为终端分配无线接入网级别的寻呼区域，此时，该指示信息可以为终端允许使用无线资源控制RRC不活跃状态的区域信息或终端允许使用RRC不活跃状态的指示；在此种情况下，接入网节点将所述寻呼区域通过空口消息(例如，RRC消息)直接发送给所述终端，且当所述终端再次与接入网节点连接时，所述接入网节点会重新为终端确定无线接入网级别的寻呼区域。
可选地，所述指示信息为：终端允许使用无线资源控制RRC不活跃状态的区域信息；或者终端允许使用RRC不活跃状态的指示。
需要注意的是，所述终端允许激活RRC不活跃状态的指示可以被隐式的 指示，例如终端低移动性指示或终端不移动指示。
具体地，当所述指示信息为终端允许使用无线资源控制RRC不活跃状态的区域信息时，步骤32在具体实现时，包括：在所述终端允许使用RRC不活跃状态的区域信息中，为终端确定基于小区粒度的寻呼区域，其中，所确定的基于小区粒度的寻呼区域被终端允许使用RRC不活跃状态的区域所包含。需要说明的是，当核心网节点为接入网节点指示了终端允许使用RRC不活跃状态的区域信息时，接入网节点需要在指示的该区域信息中选择一部分区域作为给终端确定的新的寻呼区域。
具体地，当所述指示信息为终端允许使用RRC不活跃状态的指示时，步骤32在具体实现时，包括：根据终端允许使用RRC不活跃状态的指示，为终端确定基于小区粒度的寻呼区域。
需要说明的是，当核心网节点为给接入网节点指示终端允许使用RRC不活跃状态的区域信息时，接入网节点依据终端的移动性信息和网络侧信息直接为终端确定新的寻呼区域。
需要说明的是，为终端确定基于小区粒度的寻呼区域的主要方式为：获取接入网节点侧的网络部署和配置以及所述终端的移动性特征信息；根据所述网络部署和配置以及所述终端的移动性特征信息，为终端确定基于小区粒度的寻呼区域。
下面分别在实际应用中对上述方法的应用进行说明。
一、如图4所示，在终端附着到网络(即Attach过程)或发起位置更新过程(即TAU过程)中，确定无线接入网级别的寻呼区域的主要实现过程为：
步骤41，UE附着到网络或者发起位置更新过程。
步骤42，确定终端的RRC inactive允许区域。
核心网节点(即新一代核心网中的节点)根据UE的移动性、UE的签约，网络配置与策略等确定终端是否可以使用RRC inactive connected状态(即使用RRC inactive模型或者进入RRC inactive connected状态)，在终端可以使用RRC inactive connected状态时，确定UE可以进入RRC inactive connected状态的区域，记为RRC inactive允许区域，并分配跟踪区列表(TA list)或小区 列表(cell list)覆盖该RRC inactive允许区域。
步骤43，将为终端进行寻呼区域分配的指示信息发送给接入网节点；
核心网节点指示当前服务UE的接入网节点，并指示该UE允许使用RRC inactive，进一步的，核心网节点(例如移动性管理功能实体)将允许UE使用RRC inactive的区域发送给RAN节点。
步骤44，建立接入网节点和核心网节点之间控制平面连接和用户平面连接，即建立NG2接口和NG3接口的连接。
步骤45，核心网节点将跟踪区列表或小区列表分配给UE。
步骤46，接入网节点根据核心网节点的指示信息，为终端确定RAN level的寻呼区域；
若接入网节点接收到RRC inactive允许区域后，进一步根据接入网侧的网络部署和配置(例如该接入网节点作为锚点，能够服务的区域)，以及该UE的移动性特征，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态，保证RAN level的寻呼区域被RRC inactive允许区域所包含。
若接入网节点仅接收到允许使用RRC inactive状态的指示，则自行根据接入网侧的网络部署和配置(例如该接入网节点作为锚点，能够服务的区域)以及该UE的移动性特征，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态。
步骤47，接入网节点将该寻呼区域通知给UE。
步骤48，释放RRC连接后，UE和接入网节点进入RRC inactive状态。
二、如图5所示，在终端发起服务请求过程中，确定无线接入网级别的寻呼区域的主要实现过程为：
可选步骤：在终端Attach(但不建立PDU会话)或TAU过程中，当核心网节点(例如，移动性管理功能实体)根据UE的移动性、UE的签约，网络配置与策略等确定终端是否可以使用RRC inactive模型或者进入RRC inactive connected状态时，若可以使用RRC inactive模型或者进入RRC inactive connected状态，则确定UE可以进入RRC inactive connected状态的区域，记为RRC inactive允许区域。此时，核心网移动性管理功能可以不立 刻指示RAN激活RRC inactive状态。
步骤51，UE发起服务请求(Service Request)过程。
步骤52，将为终端进行寻呼区域分配的指示信息发送给接入网节点；
核心网可能向RAN节点指示当前服务UE的接入网节点(这个指示是可选的，如果移动性管理功能已经在Attach或TAU过程中向该RAN节点提供过指示，则无需提供)，该UE允许使用RRC inactive，进一步的，移动性管理功能将允许UE使用RRC inactive的区域发送给RAN节点。
步骤53，建立用户面的数据传输路径并进行数据传输。
步骤54，接入网节点根据核心网节点当前的指示或者之前已经收到的指示，确定进行RAN level寻呼区域的分配。
若RAN节点接收到RRC inactive允许区域后，进一步根据接入网侧的网络部署和配置(例如该接入网节点作为锚点，能够服务的区域)，以及该UE的移动性特征，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态，保证RAN level的寻呼区域被RRC inactive允许区域所包含。
若接入网节点仅接收到允许使用RRC不活跃状态的指示，则自行根据接入网侧的网络部署和配置(例如该接入网节点作为锚点，能够服务的区域)，以及该UE的移动性特征，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态。
步骤55，接入网节点在RRC连接释放过程中，将该寻呼区域通知给UE，释放RRC连接后，UE和接入网节点进入RRC inactive状态。
可选地，当终端已经进入RRC不活跃状态，在移动过程中当移出当前的寻呼区域时，核心网节点会触发接入网节点为终端进行寻呼区域的重新分配，在此种情况下，步骤31的具体实现方式为：获取核心网节点在接收到终端的位置更新请求时，发送的为终端进行寻呼区域分配的指示信息。
相应地，步骤32的具体实现方式为：
将所述寻呼区域发送给所述核心网节点，使得所述核心网节点将所述寻呼区域发送给所述终端；或
将所述寻呼区域通过空口消息直接发送给所述终端。
三、如图6所示，在终端移出当前的无线接入网级别的寻呼区域过程中，由核心网节点触发的无线接入网级别的寻呼区域的重分配的方式一的主要实现过程为：
步骤61，UE移出当前的RAN level Paging area之后，发送位置更新请求到核心网节点，该位置更新请求中携带有移出RAN level Paging area的指示(如果RAN level Paging area和TA list或cell list不对齐)。
步骤62，核心网节点首先通知原接入网节点删除UE的上下文(Context)和NG2和NG3连接。
步骤63，核心网节点检查UE是否仍然在allowed area。
需要说明的是，该步骤63为可选步骤，当RAN level Paging area可能大于TA list或cell list时，执行该步骤63。
步骤64，核心网节点指示当前服务UE的接入网节点(新接入网节点)，该UE允许使用RRC inactive，进一步的，核心网节点将允许UE使用RRC inactive的区域发送给新接入网节点。
步骤65，当新接入网节点根据核心网节点的指示(即核心网节点发送的允许UE使用RRC inactive的区域)等，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态。
步骤66，新接入网节点根据核心网节点的指示为UE建立NG3连接。
步骤67，新接入网节点将该寻呼区域通知给核心网节点。
步骤68，核心网节点将新分配的寻呼区域通知给UE，使得UE和RAN在释放RRC连接后，进入RRC inactive状态。
四、如图7所示，在终端移出当前的无线接入网级别的寻呼区域过程中，由核心网节点触发的无线接入网级别的寻呼区域的重分配的方式二的主要实现过程为：
步骤71，UE移出当前的RAN level Paging area之后，发送位置更新请求到核心网节点，该位置更新请求中可能携带有移出RAN level Paging area的指示(例如在RAN level Paging area和TA list或cell list不对齐时，UE向核心网节点提供该指示)。
步骤72，核心网节点首先通知原接入网节点删除UE的上下文(Context) 和NG2和NG3连接。
步骤73，核心网节点检查UE是否仍然在allowed area；
需要说明的是，该步骤73为可选步骤，当RAN level Paging area可能大于TA list或cell list时，执行该步骤73。
步骤74，核心网节点指示当前服务UE的接入网节点(新接入网节点)，该UE允许使用RRC inactive，进一步的，核心网节点将允许UE使用RRC inactive的区域发送给新接入网节点。
步骤75，新接入网节点根据核心网节点的指示(即核心网节点发送的允许UE使用RRC inactive的区域)等，为该UE分配UE specific的RAN level寻呼区域，并确定UE在该寻呼区域可以使用RRC inactive connected状态。
步骤76，新接入网节点根据核心网节点的指示为UE建立NG3连接。
步骤77，核心网节点在完成NG3连接建立后，向UE返回位置更新接受(Accept)消息。
步骤78，新接入网节点通过RRC消息将新的寻呼区域通知给UE，例如RRC连接释放消息，使得UE和当前服务UE的接入网节点在释放RRC连接后，进入RRC inactive状态。
可选地，当终端已经进入RRC不活跃状态，在移动过程中当移出当前的寻呼区域时，终端会直接触发接入网节点会为终端进行寻呼区域的重新分配，在此种情况下，步骤31的具体实现方式为：接收终端移出当前的寻呼区域后，发送的为终端进行寻呼区域分配的指示信息。
需要说明的是，该指示信息可以包含在终端发送的请求消息中，也可以为终端发送的一条新消息。
还需要说明的是，当终端移出当前的无线接入网级别的寻呼区域后发送的为请求消息时，该请求消息中可能需携带之前驻留的小区信息，以使得在服务终端的接入网节点发生变化时，收到终端请求消息的接入网节点能够找到之前的接入网节点(即第一接入网节点)。
相应地，所述步骤32在具体实现时，包括：
步骤321，根据所述指示信息，判断终端是否可以使用RRC不活跃状态；
步骤322，若终端可以使用RRC不活跃状态，则为终端确定寻呼区域。
步骤323，若终端不可以使用RRC不活跃状态，则发送RRC不活跃状态去激活消息给核心网节点，使得核心网节点通知所述终端不能继续使用RRC不活跃状态。
可选地，所述步骤321在实现时可以包括：
步骤3211，根据所述指示信息，获取终端允许使用RRC不活跃状态的区域信息；
具体地，该步骤321的具体实现方式为：向第一接入网节点发送请求，以获取所述终端的允许使用RRC不活跃状态的区域信息；或者
向核心网节点发送请求，以获取所述终端的允许使用RRC不活跃状态的区域信息。
需要说明的是，该第一接入网节点指的是原来服务终端的接入网节点，即旧的接入网节点。具体实现中，可由当前接入网节点使用终端之前驻留的小区信息查询获得。
步骤3212，根据所述终端允许使用RRC不活跃状态的区域信息，判断终端是否可以使用RRC不活跃状态。
需要说明的是，在步骤322之后，所述确定寻呼区域的方法，还包括：
发送路径切换请求到核心网节点，使得所述核心网节点为所述终端更新接入网节点和核心网节点之间的控制平面连接和用户平面连接。
需要说明的是，在此种情况下，接入网节点会将所述寻呼区域通过空口消息直接发送给所述终端。
五、如图8所示，在终端移出当前的无线接入网级别的寻呼区域过程中，由终端直接触发的无线接入网级别的寻呼区域的重分配的主要实现过程为：
步骤81，UE移出当前的RAN level Paging area之后，发送包含有请求寻呼区域分配的指示信息的RRC消息到接入网节点，请求RAN level Paging area的重分配，该指示信息中包括旧小区(old cell)ID。若该RRC消息发送到原接入网节点，则由原接入网节点重新分配RAN level Paging area，并通知UE，否则执行步骤82。
步骤82，新接入网节点向原接入网节点发送消息，请求执行类似X2切换流程或者新的UE上下文传递流程，目的是从原接入网节点获取UE的移动 性Context和会话Context。同时，原接入网节点应向新的接入网节点提供allowed area。
步骤83，原接入网节点向新接入网节点反馈相关信息。
步骤84，新接入网节点根据allowed area确定UE可以使用RRC inactive状态(例如，新接入网节点的服务区域和allowed area有重叠)，新接入网节点为该UE分配UE specific的RAN level寻呼区域，并确定UE在该区域可以使用RRC inactive connected状态。若New RAN节点确定UE不能继续使用RRC inactive状态，则拒绝UE的请求，并指示UE不能继续使用RRC inactive状态。
步骤85，新接入网节点发送路径切换请求到核心网节点。
步骤86，更新该UE的NG2，NG3连接，并且由核心网节点完成NG3的连接建立。
步骤87，新接入网节点通过RRC消息将新的寻呼区域通知给UE，例如RRC连接释放消息，使得UE和RAN在释放RRC连接后，进入RRC inactive状态。
步骤88，新接入网节点通知原接入网节点删除UE的Context、NG2和NG3连接。
需要说明的是，当核心网节点确定UE不能继续使用RAN level Paging(例如UE离开在allowed area)。核心网节点通知原接入网节点删除UE的Context、NG2和NG3连接，核心网节点返回位置更新接受消息，通知UE不能继续使用RRC inactive状态，并可能分配新的TA list。
需要说明的是，通过根据为终端进行寻呼区域分配的指示信息，确定终端的无线接入网级别的寻呼区域，实现了终端在RRC不活跃状态下的无线接入网级别的寻呼区域的确定，保证了网络通信的完整性。
