具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1为本公开实施例可应用的一种区域更新系统的结构图，如图1所示，包括多个用户终端11和网络侧设备12，其中，用户终端11可以是UE(User Equipment)，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备。用户终端11可以与网络侧设备12建立通信，其中，附图中的网络可以表示用户终端11与网络侧设备12无线建立通信，网络侧设备12可以是基站，基站可以是宏站，如LTE eNB、5G NR NB等，或者网络侧设备12可以是传输接收点(TRP，Transmission Reception Point)，或者网络侧设备12可以是接入点(AP，access point)。
需要说明的是，在本公开实施例中并不限定用户终端11和网络侧设备12的具体类型，用户终端11和网络侧设备12的具体功能将通过以下多个实施例进行具体描述。
参见图2，图2是本公开实施例提供的一种区域更新方法的流程图，如图2所示，包括以下步骤：
步骤201、处于非激活状态的用户终端发起随机接入，向网络侧设备发送网络侧通知区域(RAN-based notification area)更新指示信息或者网络侧通知区域更新请求信息。
本公开实施例中，上述处于非激活状态的用户终端可以是在移动性方向 进行小区重选的用户终端，且网络侧设备可以保存有该用户终端核心网到无线网(CN-NR RAN)的用户面和控制面连接，另外，该用户终端的接入层的上下文存储在该用户终端和至少一个网络侧设备中。
另外，本公开实施例中，处于非激活状态的用户终端初始化通知由网络侧设备发送，即由网络侧设备初始化通知处于非激活状态的用户终端，该通知可以是网络侧设备寻呼处于非激活状态的用户终端的通知或者其他通知，对此不作限定。
且本公开实施例中，处于非激活状态的用户终端的网络侧通知区域由网络侧(例如：RAN侧)管理，且网络侧(例如：RAN侧)知道用户终端属于哪一个网络侧通知区域。
本公开实施例中，网络侧通知区域可以是由网络侧(例如：RAN侧)管理，且网络侧通知区域可以包含一个或者多个小区，具体可以是由网络侧设备决定；另外，由网络侧(例如：RAN侧)发起针对该网络侧通知区域内用户终端的通知。另外，需要说明的是，本公开实施例中，网络侧通知区域还可以称作通知区域或者通知管理区域等区域，其具体为包括一个或者多个小区的区域，且由网络侧(例如：RAN侧)决定。
在步骤201中当用户终端确定需要发起网络侧通知区域更新时，就可以发起随机接入，向网络侧设备发送网络侧通知区域更新指示信息或者网络侧通知区域更新请求信息。其中，步骤201可以在发起随机接入过程中向网络侧设备发送网络侧通知区域更新指示信息或者网络侧通知区域更新请求信息，该网络侧设备可以理解为用户终端的服务网络侧设备(例如：服务基站)。
步骤202、用户终端接收所述网络侧设备发送的网络侧通知区域信息，并根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息。
本公开实施例中，在网络侧设备接收到上述网络侧通知区域更新请求信息后，就可以向用户终端返回网络侧通知区域信息，从而步骤202可以接收到网络侧设备发送的网络侧通知区域信息，并根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息。当用户终端接收到上述网络侧通知区域信息，就可以完成网络侧通知区域的更新。且网络侧设备发送上述网络侧通知区域信息后，就可以确定用户终端的网络侧通知区域，即确定用 户终端的位置，从而在该区域内向用户终端发送通知，以实现网络侧通知能够到达处于非激活状态的用户终端。
本公开实施例中，上述方法可以应用于当前通信系统或者未来通信系统，例如：5G通信系统或者6G通信系统等等。
本公开实施例中，处于非激活状态的用户终端发起随机接入，向网络侧设备发送网络侧通知区域更新指示信息或者网络侧通知区域更新请求信息；所述用户终端接收所述网络侧设备发送的网络侧通知区域信息，并根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息，从而实现对处于非激活状态的用户终端进行网络侧通知区域的更新。
参见图3，图3是本公开实施例提供的另一种区域更新方法的流程图，如图3所示，包括以下步骤：
步骤301、处于非激活状态的用户终端发起随机接入，并向网络侧设备发送随机接入请求消息，所述随机接入请求消息中包括所述网络侧通知区域更新指示信息。
本公开实施例中，处于非激活状态的用户终端发起随机接入可以是由网络侧设备触发的，也可以是由用户终端触发的，或者周期性触发的，例如：所述处于非激活状态的用户终端发起随机接入，包括：
所述处于非激活状态的用户终端接收所述网络侧设备发送的寻呼消息，当所述寻呼消息中包含网络侧通知区域列表更新字段时，发起随机接入；
或者，
所述处于非激活状态的用户终端从原小区移动到目标小区，读取所述目标小区的网络侧通知区域标识，当所述目标小区的网络侧通知区域标识没有包含在所述用户终端保存的网络侧通知区域信息中时，发起随机接入；
或者，
所述处于非激活状态的用户终端每隔预设时长，发起随机接入。
其中，上述寻呼消息可以是当网络侧设备给上述用户终端重新配置网络侧通知区域信息时，向上述用户终端发送的寻呼消息。另外，上述网络侧通知区域指示可以是上述寻呼消息中的网络侧通知区域信息更新字段，通过该字段指示网络侧配置给用户终端的网络侧通知区域列表已经更新，触发用户 终端发起网络侧通知区域更新。通过上述寻呼消息可以实现由网络侧设备及时触发用户终端进行网络侧通知区域更新，以避免网络侧配置给用户终端的网络侧通知区域信息已经更新，但用户终端没有更新而导致的用户终端无法接收到网络侧通知的问题，以实现用户终端能够及时发起网络侧通知区域更新。
上述用户终端从原小区移动到目标小区后可以是，当用户终端从服务小区移动到另外一个目标小区，用户终端在移动到目标小区后，就可以读取到该目标小区的网络侧通知区域标识是否在用户终端保存的网络通知区域信息之中，如果不在，则触发用户终端发起网络侧通知区域更新。该实施方式中，可以实现用户终端移动到一个小区后，就可以检测该小区的网络侧通知区域标识是否在用户终端保存的网络侧通知区域信息，即检测目标小区是否与用户终端的原服务小区是否属于同一个网络侧通知区域，如果不属于则需要发起随机接入，在实现用户终端在移动终端另一个网络侧通知区域后，能及时接收到网络侧通知。
另外，用户终端发起随机接入可以是周期性触发的，例如：用户终端可以根据预先定义的周期性定时器，发起周期性的随机接入。
需要说明的是，上述发起随机接入的实施方式同样可以应用到第一实施例，对此不作赘述，且可以达到相同的有益效果。
另外，通过步骤301可以实现通过随机接入请求消息发送上述网络侧通知区域更新指示信息，从而实现在进行网络侧通知区域更新时，不需要增加额外的消息传递，从而可以节约网络资源。
该实施方式中，上述随机接入请求还可以包括随机接入前导序列。这样可以实现通过上述随机接入请求实现随机接入和网络侧通知区域更新，以节约信令开销和网络资源。
可选的，所述网络侧通知区域更新指示信息包括所述用户终端的标识和/或数据标志，所述数据标志用于指示所述用户终端是否存在上行数据或信令需要发送；所述随机接入响应还包括所述用户终端的标识，当所述数据标志指示所述用户终端存在上行数据或信令需要发送时，所述随机接入响应还包括上行授权信息。
该实施方式中，通过上述用户终端的标识可以让网络侧设备识别处于非激活状态的用户终端。另外，上述数据标志可以是使用1比特来标识，0标识没有上行数据或信令需要发送，1标识由上行数据或信令需要发送，从而实现节约信令开销。
当然，本公开实施例中，上述网络侧通知区域更新请求信息还可以包括其他信息，对此不作限定。且在一些场景中，上述网络侧通知区域更新请求信息不包括上述数据标志也是可以实现的。
另外，该实施方式中，还可以实现若数据标志指示所述用户终端存在上行数据或信令需要发送，网络侧设备在上述随机接入响应添加上行授权信息，从而实现在用户终端进行网络侧通知区域更新过程中，为用户终端授权上行资源，以让用户终端完成上行数据或信令的发送，且该过程中不需要额外增加信令传输，从而节约网络资源。且由于只有用户终端存在上行数据或信令发送时，才在随机接入响应中添加上行授权信息，这样可以节约信令开销，因为，如果上述数据标志指示用户终端不需要发送上行数据或信令，则网络侧设备在上述随机接入响应就不添加上行授权信息。且该实施方式中，上述上行授权信息可以称作上行授权字段，该上行授权字段用于添加在随机接入响应的MAC RAR中，即如果指示用户终端有上行数据或信令发送，则随机接入响应的MAC RAR中会包含网络侧通知区域信息和上行授权字段，反之只包含网络侧通知区域信息。
另外，该实施方式中，网络侧设备可以是以网络侧通知区域响应消息的形式向用户终端发送的用户终端的标识和网络侧通知区域信息，即网络侧通知区域响应消息可以包括用户终端的标识和网络侧通知区域信息，而上述随机接入响应中包括该网络侧通知区域响应消息。
可选的，所述用户终端的标识包括：国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)、SAE临时移动台标识符(SAE Temporary Mobile Station Identity，S-TMSI)、小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，或者新定义终端标识，所述新定义终端标识由网络侧设备分配，且在网络侧配置给所述用户终端的网络侧通知区域内具有唯一性；
其中，该实施方式中，可以实现在随机接入请求中携带上述IMSI、S-TMSI、C-RNTI或者新定义终端标识，以便让网络侧设备可以直接根据该标识识别出处于非激活状态的用户终端。
且可以实现新定义的UE标识(即LTE系统中没有的用户终端标识)。且上述用户终端的标识可以由网络侧设备分配，这样可以实现网络侧设备可以更好的对各网络侧通知区域内的用户终端进行管理，以提高网络性能。且用户终端的标识在网络侧配置给所述用户终端的网络侧通知区域内具有唯一性，那么，就可以实现在同一个网络侧通知区域内，不同用户终端存在不同的标识，以对网络侧通知区域内的用户终端进行区分。
可选的，所述新定义终端标识随所述用户终端的网络侧通知区域的更新而改变。
该实施方式中，可以实现同一个用户终端在不同的网络侧通知区域内存在不同的标识，以方便网络侧对用户终端的网络侧通知区域进行有效识别和管理。
302、用户终端接收所述网络侧设备发送的随机接入响应消息，所述随机接入响应消息中包括所述网络侧通知区域信息，并根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息。
可选的，所述网络侧通知区域信息包括小区标识的列表或者网络侧通知区域标识的列表。
其中，上述小区标识的列表可以包括一个或者多个小区的标识。且本公开实施例中，小区标识包括但不限于ECGI、ECI或者Global eNB ID等小区标识。而上述网络侧通知区域标识的列表可以包括一个或者多个网络侧通知区域的标识。
另外，本公开实施例中，网络侧通知区域信息可以用于指示网络侧配置给所述用户终端的网络侧通知区域，且所述网络侧通知区域信息包括小区标识的列表。
该实施方式中，可以实现上述网络侧通知区域信息由网络侧为用户终端配置，而不需要核心网参与，从而实现网络侧更好地对用户终端的网络侧通知区域进行管理。另外，本公开实施例中，配置用户终端的网络侧通知区域 不作限定，例如：可以是网络侧根据自身的策略或者网络资源或者用户终端的业务需要等信息为用户终端配置网络侧通知区域。
需要说明的是，上述网络侧通知区域信息的实施方式同样可以应用到第一实施例，对此不作赘述，且可以达到相同的有益效果。
可选的，所述用户终端接收所述网络侧设备发送的随机接入响应消息的步骤之后，所述方法还包括：
所述用户终端检测接收到的网络侧通知区域信息与所述用户终端保存的网络侧通知区域信息是否相同；
所述用户终端根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息，包括：
若所述接收到的网络侧通知区域信息与所述用户终端保存的网络侧通知区域信息不同，则将所述用户终端保存的网络侧通知区域信息更新为所述接收到的网络侧通知区域信息。
该实施方式中，可以实现当用户终端收到网络侧设备发送的网络侧通知区域信息消息后，检查网络侧通知区域信息，如果网络侧通知区域信息发生变化，用户终端更新用户终端保存的网络侧通知区域信息。如果网络侧通知区域信息没有发生变化，则用户终端继续使用保存的网络侧通知区域信息，以实现用户终端成功完成一次网络侧通知区域更新。
需要说明的是，上述介绍的更新方式同样可以应用于第一实施例，即上述检测步骤是在用户终端接收所述网络侧设备发送的网络侧通知区域信息的步骤之后执行的，此处不作赘述，且可以达到相同的有益效果。
需要说明的是，本公开实施例中，上述网络侧设备可以是当前为用户终端服务的网络侧设备，即服务网络侧设备。另外，本公开实施例中，用户终端的网络侧通知区域信息可以是用户终端的锚定网络侧设备为用户终端配置的，这样可以实现为用户终端配置的网络侧通知区域会更加准确。其中，用户终端的锚定网络侧设备可以是指该网络侧设备保持该用户终端的核心网到无线网的用户面和控制面的连接，并保存有该用户终端的接入层上下文。
且上述网络侧设备可以是用户终端的锚定网络侧设备，该情况下该网络侧设备可以直接向用户终端发送网络侧通知区域信息；而上述网络侧设备不 是用户终端的锚定网络侧设备时，则该网络侧设备不是用户终端的锚定网络侧设备时，则该网络侧设备可以向用户终端的锚定网络侧设备发送网络侧通知区域更新请求，用户终端的锚定网络侧设备收到网络侧通知区域更新请求消息后，将网络侧通知区域更新信息发送给上述网络侧设备，该网络侧设备再以上述介绍的方式向用户终端发送网络侧通知区域信息。
本实施例中，在图2所示的实施例的基础上增加了多种可选的实施方式，且均能够实现对处于非激活状态的用户终端进行网络侧通知区域的更新。
参见图4，图4是本公开实施例提供的另一种区域更新方法的流程图，如图4所示，包括以下步骤：
步骤401、处于非激活状态的用户终端发起随机接入，并向所述网络侧设备发送消息3(Msg3)，所述消息3包括网络侧通知区域更新请求信息。

所述处于非激活状态的用户终端接收所述网络侧设备发送的寻呼消息，当所述寻呼消息中包含网络侧通知区域列表更新字段时，发起随机接入；
或者，
所述处于非激活状态的用户终端从原小区移动到目标小区，读取所述目标小区的网络侧通知区域标识，当所述目标小区的网络侧通知区域标识没有包含在所述用户终端保存的网络侧通知区域信息中时，发起随机接入；
或者，
所述处于非激活状态的用户终端每隔预设时长，发起随机接入。
其中，上述寻呼消息可以是当网络侧设备给上述用户终端重新配置网络侧通知区域信息时，向上述用户终端发送的寻呼消息。另外，上述网络侧通知区域指示可以是上述寻呼消息中的网络侧通知区域信息更新字段，通过该字段指示网络侧配置给用户终端的网络侧通知区域列表已经更新，触发用户终端发起网络侧通知区域更新。通过上述寻呼消息可以实现由网络侧设备及时触发用户终端进行网络侧通知区域更新，以避免网络侧配置给用户终端的网络侧通知区域信息已经更新，但用户终端没有更新而导致的用户终端无法 接收到网络侧通知的问题，以实现用户终端能够及时发起网络侧通知区域更新。
上述用户终端从原小区移动到目标小区后可以是，当用户终端从服务小区移动到另外一个目标小区，用户终端在移动到目标小区后，就可以读取到该目标小区的网络侧通知区域标识是否在用户终端保存的网络通知区域信息之中，如果不在，则触发用户终端发起网络侧通知区域更新。该实施方式中，可以实现用户终端移动到一个小区后，就可以检测该小区的网络侧通知区域标识是否在用户终端保存的网络侧通知区域信息，即检测目标小区是否与用户终端的原服务小区是否属于同一个网络侧通知区域，如果不属于则需要发起随机接入，在实现用户终端在移动终端另一个网络侧通知区域后，能及时接收到网络侧通知。
另外，用户终端发起随机接入可以是周期性触发的，例如：用户终端可以根据预先定义的周期性定时器，发起周期性的随机接入。
另外，通过步骤401可以实现在用户终端确定需要发起网络侧通知区域更新，用户终端向网络侧设备发起随机接入，并通过随机接入过程的Msg3和Msg4实现网络侧通知区域的更新，从而实现在随机接入过程中完成网络侧通知区域的更新，不需要增加额外的信令，从而节约网络资源和信令开销。
402、用户终端接收所述网络侧设备发送的消息4(Msg4)，所述消息4包括所述网络侧通知区域信息，并根据接收到的网络侧通知区域信息，更新自身保存的网络侧通知区域信息。

该实施方式中，关于数据标志可以参见第二实施例，此处不作赘述，且可以达到相同的有益效果。
另外，该实施方式中，上述网络侧通知区域更新请求信息还包括更新类 型信息，从而通过该更新类型信息通知网络侧设备用户终端触发网络侧通知区域更新的触发类型，例如：网络侧通知区域更新为周期性触发的更新；或者网络侧通知区域更新为用户终端读取到目标小区的网络侧通知区域标识不在用户终端保存的网络通知区域信息之中，而触发的网络侧通知区域更新；或者网络侧通知区域更新为网络侧设备给用户终端重新配置网络侧通知区域信息触发的网络侧通知区域更新。通过上述更新类型信息可以让网络侧设备及时了解用户终端的触发方式，以让网络侧设备选择或者配置合适的网络侧通知区域信息。当然，在一些场景中，上述网络侧通知区域更新请求信息不包括更新类型信息也是可以实现的。同理，在上述随机接入请求的实施方式中，上述网络侧通知区域更新请求信息也可以包括更新类型信息，且能达到相同的有益效果。
另外，上述用户终端保存的网络侧通知区域信息可以是用户终端上次注册的网络侧通知区域信息，例如：用户终端在发起网络侧通知区域更新之前获取到的网络侧通知区域信息。通过在上述网络侧通知区域更新请求信息中包括用户终端保存的网络侧通知区域信息，可以让网络侧设备查看网络侧当前为用户终端配置或者重新为用户终端配置网络侧通知区域信息是否与用户终端保存的相同，如果不同，则配置的网络则通知区域信息发送给用户终端，如果相同，则确定用户终端所在的网络侧通知区域没有改变，该情况下，可以不向用户终端发送网络侧通知区域信息，以节约信令开销，可以只向用户终端返回一指示信息，以指示用户终端的网络侧通知区域信息不需要更新。同理，在上述随机接入请求的实施方式中，上述网络侧通知区域更新请求信息也可以包括用户终端保存的网络侧通知区域信息，且能达到相同的有益效果。
可选的，所述用户终端的标识包括：IMSI、S-TMSI、C-RNTI或者新定义终端标识，所述新定义终端标识由网络侧设备分配，且在网络侧配置给所述用户终端的网络侧通知区域内具有唯一性；
其中，该实施方式中，可以实现在随机接入请求中携带上述IMSI、S-TMSI、C-RNTI或者新定义终端标识，以便让网络侧设备可以直接根据该标识识别出处于非激活状态的用户终端。
且可以实现新定义的UE标识(即LTE系统中没有的用户终端标识)。且上述用户终端的标识可以由网络侧设备分配，这样可以实现网络侧设备可以更好的对各网络侧通知区域内的用户终端进行管理，以提高网络性能。且用户终端的标识在网络侧配置给所述用户终端的网络侧通知区域内具有唯一性，那么，就可以实现在同一个网络侧通知区域内，不同用户终端存在不同的标识，以对网络侧通知区域内的用户终端进行区分。
