具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括：终端设备10、接入网设备20和核心网设备30。
终端设备10可以指UE(User Equipment，用户设备)、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、无线通信设备、用户代理或用户装置。可选地，终端设备10还可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digita1Assistant，个人数字处理)、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，5GS(5th Generation System，第五代移动通信系统)中的终端设备或者未来演进的PLMN(Pub1ic Land Mobi1e Network，公用陆地移动通信网络)中的终端设备等，本申请实施例对此并不限定。为方便描述，上面提到的设备统称为终端设备。终端设备10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端设备10。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的设备。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为接入网设备。可选地，通过接入网设备20，终端设备10和核心网设备30之间可以建立通信关系。示例性地，在LTE(Long Term Evolution，长期演进)系统中，接入网设备20可以是EUTRAN(Evolved Universal Terrestrial Radio Access Network，演进的通用陆地无线网)或者EUTRAN中的一个或者多个eNodeB；在5G NR系统中，接入网设备20可以是RAN(Radio Access Network，无线接入网)或者RAN中的一个或者多个gNB。在本申请实施例中，所述的网络设备除特别说明之外，是指接入网设备20。
核心网设备30的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G NR系统中的核心网设备可以包括AMF(Access and Mobility Management Function，接入和移动性管理功能)实体、UPF(User Plane Function，用户平面功能)实体和SMF(Session Management Function，会话管理功能)实体等设备。
在一个示例中，接入网设备20与核心网设备30之间通过某种空口技术互相通信，例如5G NR系统中的NG接口。接入网设备20与终端10之间通过某种空口技术互相通信，例如Uu接口。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
通信系统通常支持连接态终端设备的切换过程。当正在使用网络服务的用户从一个小区移动到另一个小区，或由于无线传输业务负荷量调整、激活操作维护、设备故障等原因，为了保证通信的连续性和服务的质量，系统要将该用户与原小区的通信链路转移到新的小区上，即执行切换过程。因此，终端设备可以从第一接入网设备的小区切换到第二接入网设备的小区。在这种情况下，第一接入网设备可以称为源接入网设备或源基站，第二接入网设备可以称为目标接入网设备或目标基站。
如图2所示，其示出了相关技术提供的终端切换流程的示意图。
在切换准备阶段，由AMF向基站提供移动性控制信息，终端设备和源基站之间进行测量控制和报告。源基站根据终端设备的测量报告做出切换决定之后，向目标基站发送切换请求(Handover Request)。目标基站执行准入控制，在确定允许终端设备切换的情况下，目标基站向源基站发送切换请求响应(Handover Request Acknowledge)。
在切换执行阶段，RAN切换启动，终端设备从旧小区分离，同步到新小区。源基站向目标基站发送 SN(Serial Number，序列号)状态转移(SN Status Transfer)。源基站从UPF获取缓冲数据和新数据，然后将上述用户数据发送给目标基站。目标基站缓存来自源基站的用户数据。至此，RAN切换完成。
在切换完成阶段，目标基站向AMF发送路径切换请求(Path Switch Request)，AMF与UPF执行路径切换，之后UPF向源基站发送结束指示信息(End Marker)，源基站向目标基站转发该结束指示信息。AMF向目标基站发送路径切换请求响应(Path Switch Request Acknowledge)，目标基站向源基站指示将终端设备的上下文信息进行释放。
对于图2所示的切换流程，在网络实现上，源基站可以根据终端设备侧的测量上报(包含多个小区的测量结果)，针对多个目标小区同时或先后发起切换准备/请求消息(可以基于直连的X2/Xn接口，或者通过和MME(Mobility Management Entity，移动性管理实体)/AMF之间的S1/N2接口)。每个目标小区在收到切换准备/请求消息后根据自己的RRM(Radio Resource Management，无线资源管理)算法进行接入控制，并在通过接入控制的前提下向源小区所在基站发送切换请求应答消息(如接入控制未通过则响应切换请求失败消息)，其中携带目标小区生成的切换命令。源基站根据自己的RRM算法在返回切换应答的多个目标小区中选择一个作为最终的切换目标小区，并将与该目标小区对应的切换命令通过RRC(Radio Resource Control，无线资源控制)重配置消息发送给终端设备，进而实现网络对切换过程的完全控制。
图3示出了基于条件触发的切换过程(conditional handover)的流程图。
针对高速移动场景和高频部署场景存在频繁切换以及切换容易失败的问题，相关标准组织为LTE和NR系统引入了基于条件触发的切换过程。其基本原理是终端设备根据网络侧配置的条件在评估与目标小区相关的条件触发时按照预先配置好的切换命令执行向该目标小区的切换(即触发随机接入过程和发送切换完成消息)，避免由于高速移动进入覆盖差区域来不及或无法发送测量上报和接收到切换命令的问题。当前标准协议中将测量事件A3和/或A5定义为条件切换的触发条件。
如图3所示，在基于条件触发的切换过程中，终端设备和源基站之间可以先进行测量配置和报告(该步骤为可选步骤)，之后源基站和目标基站之间进行切换准备。源基站向终端设备发送切换命令，该切换命令中包括小区选择条件，终端设备在检测到目标小区满足该小区选择条件时，向该目标小区中的目标基站发起接入过程。
目前标准中定义的测量事件包括：
测量事件A1(Event A1)：表示服务小区信号质量高于一定门限，满足此条件的事件被上报时，基站停止异频/异系统测量。
测量事件A2(Event A2)：表示服务小区信号质量低于一定门限，满足此条件的事件被上报时，基站启动异频/异系统测量。
测量事件A3(Event A3)：表示同频/异频邻区质量高于服务小区质量，满足此条件的事件被上报时，源基站启动同频切换请求。一般来说是基于覆盖的切换。
测量事件A4(Event A4)：表示异频邻区质量高于一定门限量，满足此条件的事件被上报时，源基站启动异频切换请求。一般来说是基于负荷均衡的切换。
测量事件A5(Event A5)：表示服务小区质量低于一定门限并且邻区质量高于一定门限。
测量事件B1(Event B1)：表示异系统邻区质量高于一定门限，满足此条件事件被上报时，源基站启动异系统切换请求。
测量事件B2(Event B2)：表示服务小区质量低于一定门限并且异系统邻区质量高于一定门限。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此相关标准组织开始研发5G。5G的主要应用场景包括：eMBB(Enhanced Mobile Broadband，增强移动带宽)、URLLC(Ultra-relaible and Low Latency Communication，超可靠低时延通信)、mMTC(Massive Machine Type Communication，大规模机器类通信)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内、市区、农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
然而，目前的移动性管理(例如切换)是通过信号质量(例如测量事件A3或A5)的判决来保证业务连续性的，即假设是信号质量的连续性代表了用户服务的连续性。然而，用户服务体验未必等效于用户服务的连续性，用户服务的连续性也未必等效于信号质量的连续性。用户服务体验应该与业务的QoS(Quality of Service，服务质量)需求有关，不同的用户服务有不同的移动性管理目标(比如eMBB追求大带宽，URLLC追求低时延，mMTC追求低能耗等)。未来需要针对各业务不同的QoS需求，针对移动性管理引入更精确的控制。
本申请实施例提供的一种技术方案，主要考虑结合终端设备当前的业务情况(如业务类型或业务QoS特性)，来决定测量上报评估以及切换执行条件评估，以使得切换过程更加适配当前的实际业务情况，提升切换效果。
本申请实施例提供的另一种技术方案，通过引入切换模型，基于终端设备的当前状况信息(如测量结果、速度信息、业务信息、QoS信息等)由该切换模型生成适配于终端设备的局部切换决策，以使得切换过程更加适配当前的实际业务情况，提升切换效果。
请参考图4，其示出了本申请一个实施例提供的切换方法的流程图，该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤(410～440)：
步骤410，网络设备向终端设备发送配置信息，该配置信息包括多套切换配置信息，每一套切换配置信息关联一种业务情况。
在本申请实施例中，切换配置信息用于配置与小区切换相关的操作。例如，切换配置信息可以包括测量配置信息，该测量配置信息用于配置终端设备的测量上报操作。又例如，切换配置信息可以包括切换执行条件，该切换执行条件用于配置在条件切换的场景下，触发小区切换所需满足的条件。
在本申请实施例中，针对不同的业务情况，分别配置不同的切换配置信息。业务情况是指终端设备处理的业务的相关情况。
在一个示例中，每一种业务情况包含一种业务类型或多种业务类型的组合。例如，可以依据业务特性的不同，划分出多种不同的业务类型。示例性地，业务类型包括以下至少一种：eMBB业务、URLLC业务、mMTC业务。当然，在一些其他实施例中，业务类型也可以从不同维度或粒度进行划分，如包括语音业务、视频业务、自动驾驶业务、远程医疗业务、工业自动化业务等等，本申请实施例对此不作限定。
示例性地，配置信息包括如下多套切换配置信息：切换配置信息1关联eMBB业务，切换配置信息2关联URLLC业务，切换配置信息3关联mMTC业务，切换配置信息4关联eMBB业务和mMTC业务的组合，等等。
在另一个示例中，每一种业务情况包含一种QoS特性或多种QoS特性的组合。QoS特性可以和时延、吞吐量、丢包率等因素相关。不同的QoS特性之间，存在至少一种影响因素的特性不同。例如，不同的QoS特性具有不同的时延要求。
示例性地，配置信息包括如下多套切换配置信息：切换配置信息1关联QoS特性1，切换配置信息2关联QoS特性2，切换配置信息3关联QoS特性3，切换配置信息4关联QoS特性1和QoS特性2，等等。
相应地，终端设备接收来自于网络设备的配置信息。
步骤420，终端设备获取当前的业务情况。
当前的业务情况是指终端设备当前时刻处理的业务的相关情况。
步骤430，终端设备根据当前的业务情况，从多套切换配置信息中确定目标切换配置信息。
可选地，目标切换配置信息是从上述多套切换配置信息中确定出的一套切换配置信息。
可选地，终端设备从多套切换配置信息中，将与当前的业务情况相关联的切换配置信息，确定为目标切换配置信息。
以每一套切换配置信息关联一种业务情况，每一种业务情况包含一种业务类型或多种业务类型的组合为例，结合上述示例，假设终端设备当前的业务情况为URLLC业务，那么确定切换配置信息2为目标切换配置信息；假设终端设备当前的业务情况为eMBB业务和mMTC业务的组合，那么确定切换配置信息4为目标切换配置信息。
以每一套切换配置信息关联一种业务情况，每一种业务情况包含一种QoS特性或多种QoS特性的组合为例，结合上述示例，假设终端设备当前的业务情况为QoS特性1，那么确定切换配置信息1为目标切换配置信息；假设终端设备当前的业务情况为QoS特性1和QoS特性2的组合，那么确定切换配置信息4为目标切换配置信息。
可选地，在不存在与当前的业务情况相关联的切换配置信息的情况下，从多套切换配置信息中，将与当前的业务情况匹配度最高的切换配置信息，确定为目标切换配置信息。例如，当前的业务情况为eMBB业务和URLLC业务的组合，网络设备配置的多套切换配置信息中，并没有与eMBB业务和URLLC业务的组合直接关联的切换配置信息，那么终端设备可以选择与URLLC业务关联的切换配置信息(即上述切换配置信息2)作为目标切换配置信息。需要说明的是，在不存在与当前的业务情况相关联的切换配置信息的情况下，目标切换配置信息的选择方式可以由网络设备配置并指示给终端设备，例如在上述配置信息中进一步携带相关信息以进行指示，也可以由终端设备自己决定，本申请实施例对此不作限定。
步骤440，终端设备根据目标切换配置信息，执行与小区切换相关的操作。
终端设备在从多套切换配置信息中，确定出与当前的业务情况相适配的目标切换配置信息之后，便可根据该目标切换配置信息，执行与小区切换相关的操作。
综上所述，本申请实施例提供的技术方案，通过针对不同的业务情况，配置多套切换配置信息，每一套切换配置信息关联一种业务情况，使得终端设备在执行与小区切换相关的操作(如测量上报评估或切换执行条件评估)时，可以结合当前的业务情况，选择与当前的业务情况相适配的目标切换配置信息，来指导终端设备执行与小区切换相关的操作，使得切换过程更加适配当前的实际业务情况(如业务类型或业务QoS特性)，提升切换效果。
在上文已经介绍，切换配置信息可以包括测量配置信息或者切换执行条件，下面通过图5和图6两个实施例，分别对这两种情况进行介绍说明。
请参考图5，其示出了本申请另一个实施例提供的切换方法的流程图，该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤(510～540)：
步骤510，网络设备向终端设备发送配置信息，该配置信息包括多套测量配置信息，每一套测量配置信息关联一种业务情况。
测量配置信息用于配置终端设备的测量上报操作。例如，终端设备可以根据该测量配置信息进行测量上报评估，如决定是否需要进行测量上报以及对哪个或哪些小区进行测量上报。
可选地，测量配置信息包括测量事件，该测量事件用于指示执行测量上报操作所需满足的事件。例如，不同的测量配置信息中，可以包括不同的测量事件或者包括不同的测量事件组合。测量事件可以是上文列举的几种测量事件，也可以根据实际需求扩展的一些测量事件，本申请实施例对此不作限定。
另外，在本实施例中，每一种业务情况可以包含一种业务类型或多种业务类型的组合，也可以包含一种QoS特性或多种QoS特性的组合，相关介绍说明可参见上文实施例，本实施例对此不再赘述。
相应地，终端设备接收来自于网络设备的配置信息。
步骤520，终端设备获取当前的业务情况。
步骤530，终端设备根据当前的业务情况，从多套测量配置信息中确定目标测量配置信息。
可选地，目标测量配置信息是从上述多套测量配置信息中确定出的一套测量配置信息。
