Abstract

本申请提供一种终端设备的网络接入方法及装置。采用该方法，终端设备能够根据自身的移动路线以及一个或多个网络小区的网络部署信息选择一个或多个上报小区，进而发起网络小区切换过程以请求切换至一个或多个上报小区中的一个小区。由于上报小区是根据终端设备的移动路线和网络小区的网络部署信息选择的，因此上报小区与终端设备的移动路线更加匹配，可提高网络接入准确度。除此之外，由于终端设备在接入目标小区时不再进行搜索和测量上报小区以外的小区，因此减少了不必要的测量以及重选，从而减少了终端和网络侧的信令交互、节约了终端的电池功耗。

背景技术
目前5G(5th-generation)移动通信技术中，包括接入网设备在内的移动通信网络根据终端设备(UE)的移动路线信息可以为终端设备提供高可靠性的网络接入服务，以满足例如5G垂直行业等场景下对网络服务的可靠性需求。
当前的网络接入管理办法为：UE接收和测量网络信号时，由UE进行网络的选择和接入操作。具体在终端移动时，需要UE和接入网执行相关的信号测量和解析、网络选择等操作，并由UE在多个网络小区之间采用竞争性的随机接入方式进行接入，不能保证接入的可靠性。此外，基站给UE配置切换需要测量的小区较多，或者广播的用于小区重选的小区过多，可能导致UE额外多搜索多个小区或频率，造成功耗浪费，UE切换或驻留在不合适小区也有可能导致乒乓效应，增加终端与网络间的额外信令交互，加重网络负担。

另外，本申请实施例提供的终端设备的网络接入方法，还可以用于5G垂直业务场景，该场景下的无线通信系统可具有如图4所示架构。
其中，垂直行业控制中心(也可称为控制中心)，是指垂直行业(例如5G垂直行业中)中用于对控制终端设备的移动路线和移动速度等进行控制的管理设备，垂直行业控制中心 可用于根据终端设备的类型或终端设备的标识(用于标识终端设备)等信息，分别针对终端设备制定其移动路线和移动速度，使得终端设备按照预定的规则进行移动，或执行相应的操作。垂直行业控制中心还可指定终端设备的移动速度以及何时开始移动，从而可控制终端设备在预定的时刻移入和/或移出特定区域。示例性的，垂直行业控制中心可通过NEF提供的对外通信接口连接至NEF。
在本申请中，5G垂直行业包括但不限于港口、铁路以及工厂等行业，这些5G垂直行业中的终端设备可包括以上行业中使用的移动机器人(mobile robot)、自动导引运输车(automated guided vehicle，AGV)、传感器、者控制设备或者车辆(vehicle)、列车、航空器或船只等可移动装置上的设备等。应理解，本申请实施例提供的终端设备的网络接入方法可以用于智能工厂或智能交通等5G垂直行业中的终端设备网络接入场景，或者可以用于非5G垂直行业中的终端设备网络接入场景，如应用于非5G垂直行业中的公路或铁路运输场景下车载设备的网络接入，本申请不做具体限定。
以图4为例，5G垂直行业中的UE，可通过接入网设备(如RAN站点)接入核心网的AMF，从而获取网络服务。在5G垂直行业场景下，这里所述的UE可以具有不同的类型，例如UE可以是非移动设备或移动设备，也可以是汽车、飞行器或者机器人等等。UE的类型与终端设备的行为特征有关，例如，若UE是非移动设备、移动速度较慢或者移动距离较短的设备，则该UE一般不会发生接入网设备的切换。示例性的，垂直行业控制中心可通过UE的类型标识或其他类型信息，标识UE的类型。另外，还可根据UE的组标识(group ID)区分UE的类型，例如，垂直行业控制中心可针对同一类型的UE配置相同的组标识，也可将UE的类型标识，或与类型标识对应的标识作为组标识。
应理解，本申请并不限制该垂直行业中的UE数量，图4中所示出的有限个垂直行业中的UE仅仅是举例说明，不应理解为对本申请实施方式的限制。另外，本申请并不限制垂直行业中的UE与接入网设备连接的方式，例如，可以每个UE连接至一个接入网设备，也可以由多个UE接入同一个接入网设备，图4中所示出的UE与接入网设备之间的连接关系仅仅是举例说明，不应理解为对本申请实施方式的限制。

如图4所示无线通信系统还可包括管理设备，或称接入网设备的管理设备，如RAN操作维护管理(operation administration and maintenance，OAM)设备(或称OAM)。在本申请中，管理设备可通过与NEF之间的通信接口与NEF实现交互。管理设备还可与RAN设备之间通过通信接口连接。应理解，本申请以RAN OAM为例对管理设备所执行的操作进行说明，但不应理解为本申请在实施中只能以RAN OAM作为管理设备，在5G或未来 通信，如6G中，管理设备仍可以是RAN OAM网元，或有其它的名称，本申请不做限定。
应理解，以上如图1所示的网络设备102可作为如图3所示无线通信系统中的(R)AN，终端设备101可通过网络设备102接入5G网络，如接入5G核心网和/或访问DN。以上如图1所示的网络设备102可作为如图4所示无线通信系统中的接入网设备，终端设备101可通过网络设备102接入5G网络，如接入5G核心网和/或访问DN。
以图4所示通信系统为例，垂直行业中的UE可进行接入网设备的切换(handover)，例如，由于UE的位置发生移动，UE可从一个接入网设备切换至另一个接入网设备。在本申请中，切换前UE所接入的接入网设备可被称为第一接入网设备，切换后UE所接入的接入网设备可被称为第二接入网设备。若第一接入网设备与第二接入网设备为同一接入网设备，则UE只在该接入网设备管理的多个小区之间进行小区切换。若第一接入网设备与第二接入网设备为不同的接入网设备，则UE在多个接入网设备之间进行接入网设备切换。
以上图4所示架构，介绍了本申请提供的方法应用于5G垂直行业场景时的网络架构。应理解，本申请提供的方法并不限于只在该架构所示场景中实施。例如，本申请提供的方法还可应用于公共交通场景，如铁路、公路等场景下的智能交通，此时，以上图4所示架构中的垂直行业控制中心可替换为公共交通控制中心，或具有其他名称的设备，该设备可存储场景内可供终端设备移动的道路和/或区域的地理位置。应理解，以下对于方法实施例的介绍中涉及的垂直行业控制中心，可替换为公共交通控制中心。
如图5所示，本申请实施例提供的一种终端设备的网络接入方法可包括以下步骤：
S101：终端设备获取第一信息。
其中，该第一信息包括一个或多个网络小区的网络部署信息。
以上网络小区的网络部署信息，可包括该网络小区覆盖的区域与该网络小区的标识的对应关系。
示例性的，网络小区的标识可包括网络小区的小区标识(cell ID)。
S102：终端设备根据自身的移动路线以及该一个或多个网络小区的网络部署信息，确定一个或多个上报小区。
其中，该一个或多个上报小区包括该一个或多个网络小区中的一个或多个。
S103：终端设备向第一接入网设备发送第二信息。
其中，该第二信息包括该一个或多个上报小区的标识。
相应地，该第一接入网设备接收该第二信息。
S104：第一接入网设备向终端设备发送第三信息。
其中，该第三信息用于搜索和选择目标小区，该第三信息包括该目标小区的标识，该一个或多个上报小区包括该目标小区。
相应地，该终端设备接收该第三信息。
S105：该终端设备根据该第三信息，接入该目标小区。
采用以上方法，终端设备能够根据自身的移动路线以及一个或多个网络小区的网络部署信息选择一个或多个上报小区，进而发起网络小区切换过程以请求切换至一个或多个上报小区中的一个小区，由于上报小区是根据终端设备的移动路线和网络小区的网络部署信息选择的，因此上报小区与终端设备的移动路线更加匹配，因此提高了网络接入准确度，并且，终端设备在接入目标小区时只需要搜索和测量上报小区包括的目标小区，对于上报小区以外的小区终端设备可不再进行搜索和测量，因此可减少不必要的测量以及重选，从 而减少终端和网络侧的信令交互、节约了终端的电池功耗。
示例性的，以上第一信息可包括一个或多个网络小区的标识以及该网络小区的覆盖的道路的地理位置，其中，道路或称路线，在本申请中是指允许终端设备进行移动的路线。进一步的，该第一信息还可以包括以下一个或多个：小区组标识(cell group ID)、小区组标识与允许所述终端设备进行移动的路线的信息的对应关系、每个小区的切换选择的条件。其中，小区组标识可以是管理设备设置的小区组的标识，每个小区组中的小区覆盖一个或多个允许终端设备进行移动的路线，该一个或多个允许终端设备进行移动的路线即与小区组标识对应的允许所述终端设备进行移动的路线。另外，每个小区的切换选择的条件，可用于指示切换至该小区应满足的条件，如频点条件、终端设备的切换优先级条件或者切换阈值条件等。示例性的，每个小区的切换选择的条件可包括小区的频点信息、小区允许终端设备接入的优先级信息或者小区的切换阈值信息等等。
本申请所述第一信息可承载于网络辅助信息(network assistance information)。
另外，该网络小区覆盖的区域可用该网络小区的小区覆盖信息指示，则每个网络小区的网络部署信息可包括小区覆盖信息与网络小区的标识之间的对应关系。在本申请中，小区覆盖信息可用于指示网络小区的覆盖范围。示例性的，小区覆盖信息可包括区域标识、区域名称或者经纬度。
具体的，第一信息中的网络小区覆盖的区域可包括允许终端设备进行移动的路线，此时，每个网络小区的部署信息可包括允许终端设备进行移动的路线的信息与该网络小区的标识的对应关系。其中，允许终端设备进行移动的路线的信息可包括允许终端设备进行移动的路线所对应的地理位置。示例性的，允许终端设备进行移动的路线所对应的地理位置可包括允许终端设备进行移动的路线所对应的名称或标识，和/或，允许终端设备进行移动的路线所对应的经纬度。其中，终端设备可存储或从接入网设备或其他设备接收名称(或标识)与经纬度之前的对应关系，用于根据第一信息中的路线的名称(或标识)确定路线对应的经纬度。
下面，具体介绍S101中终端设备获取第一信息的方式。
示例性的，以上第一信息，可以是该第一接入网设备(即终端设备接入的接入网设备)发送的，也可以是其他接入网设备(即终端设备接入的接入网设备以外的接入网设备)发送的，本申请不予限制。
另外，第一信息，也可以是终端设备从本地获取的。此时，第一信息可存储于终端设备本地。
具体的，若第一信息是第一接入网设备发送的，在S101之前，第一接入网设备可接收终端设备发送的初始接入(initial access)请求，并根据该请求建立与终端设备之间的连接。
示例性的，初始接入请求可用于指示终端设备的状态特征。具体的，初始接入请求可携带终端设备的类型信息，如终端设备的类型标识，第一接入网设备可根据终端设备的状态特征确定是否向终端设备发送第一信息。例如，若终端设备的类型信息指示终端设备的类型为非移动设备，则第一接入网设备可根据该类型指示信息确定不向终端设备发送第一信息。或者，若终端设备的类型信息指示终端设备的类型为移动速度较慢或者移动距离较短的设备，则第一接入网设备可根据该类型指示信息确定不向终端设备发送第一信息。若终端设备的类型信息指示终端设备的类型为移动设备，和/或，若终端设备的类型信息指示 终端设备的类型为移动速度较快或者移动距离较长的设备，则第一接入网设备可根据该类型指示信息确定向终端设备发送第一信息。
另外，初始接入请求可指示终端设备的速度(如终端设备的平均移动速度、最大或最小瞬时速度等等)，如携带速度指示信息，当终端设备的速度大于(或大于等于)第一阈值速度的情况下，第一接入网设备可根据终端设备的状态特征确定向终端设备发送第一信息；当终端设备的速度小于(或小于等于)第二阈值速度的情况下，第一接入网设备可根据终端设备的状态特征确定不向终端设备发送第一信息，其中，第一阈值速度等于第二阈值速度，或者，第一阈值速度大于第二阈值速度。
在发送第一信息时，第一接入网设备可发送广播(broadcast)消息，并在该广播消息中携带第一信息，该终端设备以及其他的终端设备均可接收广播消息，并均可从广播消息中获取第一信息。或者，第一接入网设备也可在根据请求初始接入建立与终端设备之间的连接后，通过与终端设备之间的连接向该终端设备发送消息，并在发送的消息中携带第一信息，例如，第一接入网设备向终端设备发送无线资源控制(radio resource control，RRC)连接重配置完成(RRC connection reconfiguration complete)消息，在该RRC连接重配置消息中携带第一信息，本申请也不限制将第一信息携带在其他RRC消息或者其他非RRC消息中，并向终端设备发送该消息，以实现第一信息的指示。另外，第一信息还可以是第一接入网设备以外的其他接入网设备(即终端设备未接入的接入网设备)通过广播方式发送的。
在一种可能的实现方式中，管理设备可确定以上第一信息。
示例性的，管理设备可从网络开放功能网元接收允许终端设备进行移动的路线的信息。管理设备可根据允许终端设备进行移动的路线的信息以及管理设备内配置的小区覆盖信息，确定第一信息。管理设备内配置的小区覆盖信息可以通过接收各网络小区发送的自身的小区覆盖信息的方式获得。
其中，允许终端设备进行移动的路线的信息包括允许终端设备移动的地理位置。具体的，允许终端设备进行移动的路线可包括终端设备可能移动的全部路线，其中路线可包括可供终端设备移动的公路或铁路等有形道路。该路线还可包括虚拟航线，虚拟航线的路线不受限于公路和铁路等有形道路的走向，虚拟航线例如航空器、船只等的航线，以及非公路、铁路场景可供车辆等设备行驶的虚拟路线等等)。该路线还可包括终端设备可能移动的区域，例如，车间、厂房、路口或者预设置的标记位置等。
示例性的，在确定第一信息时，当管理设备确定网络小区覆盖允许终端设备进行移动的路线中的至少一条路线时，管理设备可将该网络小区的网络部署信息携带在第一信息中，换句话说，第一信息中的每个网络小区覆盖允许终端设备进行移动的路线中的至少一条路线。此时，由于终端设备从覆盖允许终端设备进行移动的路线中的至少一条路线的网络小区中选择上报小区，而不再需要根据未覆盖允许终端设备进行移动的路线的小区选择上报小区，因此降低确定上报小区时终端设备的工作量，提高网络接入效率。
另一种实现方式中，在确定第一信息时，当管理设备确定网络小区覆盖允许终端设备进行移动的路线中的至少一条路线，且其中的至少一条路线与网络小区的中心点之间的距离(如最短距离或最大距离)不超过(或小于)第一距离时，管理设备可将该网络小区的网络部署信息携带在第一信息中。其中，第一距离小于该网络小区的半径，以提高通信质量。
应理解，网络小区的中心点，可以是网络小区覆盖范围的几何中心，也可以是网络小区归属的接入网设备所在位置。网络小区的半径是指网络小区覆盖范围内，距离网络小区中心点最远的位置与该中心点之间的距离。其中，第一距离可以是固定值，如一个提前设置的固定值。或者，第一距离可以与网络小区的半径有关，例如，第一距离的长度等于k倍网络小区的半径，0<k<1。
示例性的，管理设备可向接入网设备(应理解，这里该接入网设备可以是一个或多个，其包括但不限于如图5所示的第一接入网设备)发送第一信息。
示例性的，可由垂直行业控制中心根据当前场景中道路、标记区域、非道路或者非标记区域的布局及地理位置，确定允许终端设备进行移动的路线，并将允许终端设备进行移动的路线的信息发送至管理设备，从而，管理设备可获知允许终端设备进行移动的路线的信息。可选的，垂直行业控制中心将允许终端设备进行移动的路线的信息发送至NEF，由NEF将允许终端设备进行移动的路线的信息发送至管理设备。
垂直行业控制中心也可根据终端设备的行为特性，针对终端设备设置对应的允许终端设备进行移动的路线，例如，对于车载终端设备，由于其无法到达车辆不能到达的区域，因此此类终端设备对应的允许终端设备进行移动的路线中的位置可限于车辆能够通行的区域。应理解，针对具有同一类型标识的终端设备，由于这些终端设备的行为相似，如其可能具备相同的移动路线，或者具有相似的移动模式(移动模式如不移动、缓慢移动或快速移动等等)，因此可针对这些终端设备配置相同的允许终端设备进行移动的路线。另外，针对具有不同类型标识的终端设备，可配置不同的允许终端设备进行移动的路线，实现终端设备的灵活管理。
如图6所示，若允许UE移动的位置包括路线A、路线B、路线C以及路线D以及标记区域E(图6中椭圆区域所示)，即允许终端设备进行移动的路线包括路线A、路线B、路线C以及路线D以及区域E，则允许终端设备进行移动的路线的信息可包括以上路线A、路线B、路线C、路线D以及区域E各自的地理位置。
示例性的，管理设备内配置的小区覆盖信息可以为图6中网络小区1、网络小区2、网络小区3、网络小区4、网络小区5以及网络小区6的地理位置(以上网络小区1、网络小区2、网络小区3、网络小区4、网络小区5以及网络小区6，在图6中分别以六边形虚线表示)。
管理设备可将覆盖范围与允许终端设备进行移动的路线重合的网络小区的网络部署信息，确定为第一信息包括的一个或多个网络小区的网络部署信息。例如图6所示，网络小区1覆盖了路线A、路线B以及路线C，网络小区2覆盖了路线A，网络小区3覆盖了路线A路线C以及路线D，网络小区4覆盖路线C以及标记区域E，网络小区5覆盖了路线A、路线B、路线C以及路线D，网络小区6的边缘覆盖路线B，据此，可将网络小区1、网络小区2、网络小区3、网络小区4、网络小区5以及网络小区6的网络部署信息确定为第一信息包括的一个或多个网络小区的网络部署信息。
示例性的，上例中可设置某个网络小区所覆盖的允许终端设备进行移动的路线与该网络小区的中心点之间的距离，不超过(或小于)第一距离。假设第一距离等于0.8*网络小区的半径，由于网络小区6的边缘覆盖路线B，路线B与网络小区6的中心点之间的距离大于第一距离，因此，可将网络小区1、网络小区2、网络小区3、网络小区4以及网络小区5的网络部署信息确定第一信息，而不再根据网络小区6的网络部署信息确定第一信息。
应理解，本申请中“覆盖”，是指位置与位置之间的重叠或部分重叠，例如，当网络小区的覆盖范围与允许终端设备移动的位置重叠或部分重叠时，可称为网络小区覆盖允许终端设备移动的位置。
应理解，以上网络小区的网络部署信息，可包括网络小区的小区覆盖信息与网络小区的标识之间的对应关系。例如，如图6所示网络小区1的网络部署信息可包括网络小区1的小区覆盖信息，则网络小区的小区覆盖信息与网络小区的标识之间的对应关系可如表1所示。
网络小区的标识 小区覆盖信息
cell ID_网络小区1 范围1
cell ID_网络小区2 范围2
cell ID_网络小区3 范围3
表1
另外，以上网络小区的网络部署信息，可包括网络小区覆盖的允许终端设备进行移动的路线的信息与网络小区的标识之间的对应关系。例如，如图6所示网络小区5的网络部署信息，可包括路线A(即网络小区5对应的第一位置)的经纬度。或者，网络小区5对应的地理位置可包括路线A的名称或标识。
进一步的，若网络小区的网络部署信息包括网络小区覆盖的允许终端设备进行移动的路线的信息与网络小区的标识之间的对应关系，可设置该网络小区覆盖的允许终端设备进行移动的路线与网络小区的中心之间的距离不超过(或小于)第二距离。例如，假设第二距离等于0.8*网络小区的半径，根据图6，网络小区1的边缘还覆盖了路线A以及路线C，但对于网络小区1来说，其覆盖的路线A以及路线C距离网络小区的中心点的距离小于第二距离，此时可认为网络小区1覆盖的允许终端设备进行移动的路线不包括路线A以及路线C的地理位置，因此，网络小区1覆盖的允许终端设备进行移动的路线可包括路线B。在本申请中，对于同一个网络小区来说，第一距离可用于第二距离相等或不相等。
示例性的，仍以图6为例，若每个网络小区覆盖的允许终端设备进行移动的路线与网络小区的中心点之间的距离不超过(或小于)第二距离，其中第二距离等于0.8*网络小区的半径，则网络小区覆盖的第一位置与网络小区的标识之间的对应关系可如表2所示。
Figure PCTCN2020093763-appb-000001
表2
另外，表2中路线A对应的多个网络小区的标识，也可用于指示多个网络小区之间的方位关系。例如，第一信息中携带的网络小区5的标识的位置在前而网络小区2的标识的位置在后，可表示网络小区5位于网络小区2的北方向(或偏北方向)，网络小区2位于 网络小区5的南方向(或偏南方向)，或者，可表示网络小区5位于网络小区2的东方向(或偏东方向)，网络小区2位于网络小区5的西方向(或偏西方向)，或者，可表示网络小区5位于网络小区2的南方向(或偏南方向)，网络小区2位于网络小区5的北方向(或偏北方向)，或者，可表示网络小区5位于网络小区2的西方向(或偏西方向)，网络小区2位于网络小区5的东方向(或偏东方向)。据此，终端设备还可根据自身的移动路线以及表2，确定移动路线上线先后途经的小区，以便终端设备选择先途经的小区作为上报小区，和/或，在从该先途经的小区执行小区切换时，将该后途经的小区上报给接入网设备。
另外，第一信息可携带小区列表(cell list)，每个小区列表用于指示一条允许终端设备进行移动的路线途径的一个或多个网络小区，其中，每个网络小区覆盖其对应的一条允许终端设备进行移动的路线。例如，每条允许终端设备进行移动的路线与一个或多个网络小区的标识之间的对应关系可作为一个小区列表，第一接入网设备可向终端设备发送一个或多个小区列表，用于指示一个或多个允许终端设备进行移动的路线分别与一个或多个网络小区的标识之间的对应关系。以图6为例，路线A对应的小区列表可表示为：
Figure PCTCN2020093763-appb-000002
表3
在S102的实施中，终端设备可根据自身的移动路线的位置，以及根据一个或多个网络小区的网络部署信息，从一个或多个网络小区中确定一个或多个备选小区，其中，备选网络小区的覆盖的区域与该终端设备的移动路线存在重合。具体的，移动终端的移动路线是指终端设备的实际移动路线，终端设备可从垂直行业控制中心获取移动路线，或根据终端设备所在的可移动装置的驾驶员的指令(如驾驶员发出的控制指令)获取移动路线，并根据移动路线进行移动。仍以图6为例，UE当前沿路线C由西向东行驶，若UE的移动路线是在前方路口左转，之后沿路线B由南向北行驶，则UE的移动路线的位置是路线B的位置，UE据此可确定覆盖路线B的网络小区5以及网络小区1为备选小区。
示例性的，以表1为例，若网络小区的网络部署信息包括一个或多个网络小区的小区覆盖信息与网络小区的标识之间的对应关系，其中，若终端设备确定自身的移动路线经过表1所示范围1，则根据表1，终端设备可将“cell ID_网络小区1”标识的网络小区1作为备选小区。
又如，以表2为例，若网络小区的网络部署信息包括允许所述终端设备进行移动的路线所对应的名称、标识和/或经纬度与网络小区的标识之间的对应关系，在S102中，当终端设备确定即将行驶的移动路线为路线A时，则根据表2，路线A对应的网络小区为网络小区5和网络小区2，终端设备可从网络小区5和网络小区2中选择备选小区，如将网络小区5和网络小区2作为备选小区，或者网络小区5或网络小区2中的任意一个作为备选小区。
又如，以表3为例，若一个或多个网络小区的网络部署信息包括小区列表，其中，若UE的移动路线为路线A，则UE可根据表3确定备选小区，即，UE从网络小区5和网络小区2中选择备选小区。
示例性的，终端设备可根据选择的一个或多个备选小区，确定其他的网络小区作为上报小区，以提高网络切换的成功率，其中，一个或多个备选网络小区的覆盖的区域与该终 端设备的移动路线存在重合。示例性的，终端设备可在选择备选小区后，根据网络小区1的信号强度选择一个或多个上报小区中除该一个或多个备选小区以外的其他小区，该其他小区的信号强度与备选小区的信号强度的差值属于特定范围，且该其他小区与终端设备的移动路线存在重合，其中，特定范围可以是预设的信号强度值，特定范围的取值也可以由协议定义或者由接入网设备向终端设备进行指示。
仍以图6为例，若终端设备的移动路线为路线B，终端设备选择的备选小区为网络小区1，终端设备可以对网络小区1以及其他网络小区进行测量以获知网络小区1和其他多个网络小区的信号强度，并根据网络小区1的信号强度，从其他网络小区中选择信号强度与网络小区1接近、且覆盖范围与路线B重合的小区作为上报小区。例如，网络小区6的信号强度与网络小区1的信号强度的差值属于该特定范围，且网络小区6覆盖路线B，终端设备可据此可确定网络小区6为上报小区，从而终端设备可向第一接入网设备发送网络小区1的标识以及网络小区6的标识。
在S103的实施中，终端设备可将第二信息携带在条件切换请求(conditional handover request)消息中，并将条件切换请求消息发送至第一接入网设备，以请求进行网络切换。其中，第二信息可包括一个或多个上报小区的标识。
以上上报小区的数量可以是多个，在接收UE发送的条件切换请求消息后，第一接入网设备可根据多个上报小区的网络性能或根据本地配置，选择一个目标小区。示例性的，第一接入网设备可分别测量多个上报小区，并根据多个网络小区的信号强度选择目标小区。其中，目标小区可以是信道强度最高的上报小区。根据目标小区的标识，第一接入网设备可确定目标小区归属的接入网设备。或者，第一接入网设备可根据本地配置的目标小区选择规则，从多个上报小区中选择一个目标小区。
若目标小区归属于第一接入网设备，则第一接入网设备可向终端设备发送第三信息，其中，第三信息包括该目标小区的标识。第一接入网设备可接收来自终端设备的第一请求，该第一请求包括目标小区的标识，第一接入网设备根据第一请求，将该终端设备接入该目标小区。
示例性的，若目标小区归属于第一接入网设备，第一接入网设备可根据终端设备的上下文进行切换准备(handover preparation)。切换准备可包括确定切换配置信息(handover configuration information)，该切换配置信息可包括目标小区的标识。切换配置信息还可包括目标的频点、目标网络小区的切换门限、目标小区的切换优先级或者目标小区的随机接入前导序列(preamble)等信息中的部分或全部信息。以上该第三信息，可包括切换配置信息。
可选地，第一接入网设备可在确定准许终端设备接入目标小区后，建立与终端设备之间的连接。在建立与终端设备之间的连接后，第一接入网设备可向终端设备发送第一请求消息对应的第一响应消息，以通知终端设备完成切换。示例性的，第一响应消息可以是RRC连接响应(RRC connection response)消息。
示例性的，以上该第三信息可承载于条件切换响应(conditional handover response)消息。第一请求可以是RRC连接请求(RRC connection request)消息。
若目标小区归属于第一接入网以外的第二接入网，则第一接入网设备可向第二接入网发送第四信息，第四信息包括该终端设备的上下文以及该目标小区的标识，其中，该终端设备的上下文用于第二接入网设备确定第三信息，该第三信息用于该终端设备搜索和选择 该目标小区。
第二接入网设备可根据第四信息，向该第一接入网设备发送该第三信息，其中，第三信息包括该目标小区的标识，之后，第一接入网设备将第三信息发送至终端设备。终端设备根据第三信息搜索和选择目标小区，并向第二接入网设备发送第二请求，该第二请求包括目标小区的标识，第二接入网设备可根据第二请求将终端设备接入目标小区。
可选地，第二接入网设备可在确定准许终端设备接入目标小区后，建立与终端设备之间的连接。在建立与终端设备之间的连接后，第二接入网设备可向终端设备发送第二请求消息对应的第二响应消息，以通知终端设备完成切换。示例性的，第二响应消息可以是RRC连接响应消息。
示例性的，第二接入网设备可从第一接入网设备接收第四信息，并根据第四信息包括的终端设备的上下文进行切换准备。切换准备可包括确定切换配置信息，该切换配置信息可包括目标小区的标识。切换配置信息还可包括目标的频点、目标网络小区的切换门限、目标小区的切换优先级或者目标小区的preamble等信息中的部分或全部信息。以上该第三信息，可包括切换配置信息。
示例性的，以上第四信息可承载于条件切换请求消息。另外，以上该第三信息可承载于条件切换响应消息。第二请求可以是RRC连接请求消息。
