本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single Carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结构示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、 行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的切换方法200的流程示意图，该方法200可以但不限于由第一接入网设备执行，具体可由安装于第一接入网设备中的硬件和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
可以理解，本申请上下文中提及的第一接入网设备可以是正在为终端提供服务的服务接入网设备，如源(Source)基站，也可以是即将为切换后的所述终端提供服务的服务接入网设备，如目标(Target)基站，本实施例在此不做限制。
S210，第一接入网设备获取第一信息。
其中，所述第一信息与终端执行的感知测量任务相关。
本实施例中，所述感知测量任务可以由感知服务器以感知测量任务消息(其中可以包括感知测量配置等信息)的方式下发给所述终端，从而触发所述终端进行感知测量。可以理解，在相关技术中，虽然感知服务器在下发感知测量任务时，需要通过服务基站(如第一接入网设备)转发给终端，但是 由于该感知测量任务消息是感知协议消息，如SP1(Sensing Protocol 1)协议消息，使得该感知测量任务消息对服务基站是透明的，即服务基站并不知道终端接收到了感知服务器下发的感知测量任务。
那么在此情况下，为了能够避免由于终端进行小区切换而导致无法确保感知测量业务的连续性的问题，所述第一接入网设备可通过获取第一信息，以清楚所述终端上正在执行的感知测量任务，并据此切换到合适的目标小区。因此，在本实施例中，所述第一信息至少可以包括感知测量指示信息和/或感知辅助切换信息。
所述感知测量指示信息用于指示终端正在执行感知测量任务。其中，所述感知测量指示信息可以是一个显式的指示信息，例如，所述感知测量指示信息可通过1个比特进行显式指示，如当取值为1时表示终端正在执行感知测量任务，或有测量任务需要执行；或者，所述感知测量指示信息也可以是一个隐式的指示信息，例如，所述终端发送了第一信息或所述终端发送了感知辅助切换信息，则表示终端正在执行感知测量任务或有测量任务需要执行等。
可选的，所述感知测量指示信息的指示方式可以由协议约定或高层配置实现，本实施例在此不做限制。
所述感知辅助切换信息用于辅助所述第一接入网设备(如源基站或目标基站)对所述终端进行小区切换，如所述终端从当前的服务小区(也可理解为源小区)切换至目标小区等。
当然，在本实施例中，根据通信场景的不同，所述第一接入网设备获取第一信息的方式可以有多种。一种实现方式中，所述第一接入网设备获取第一信息的方式可以包括以下(11)-(13)中的至少一种。
(11)所述第一接入网设备接收来自所述终端的所述第一信息。
其中，在所述第一接入网设备作为服务基站(也可理解为：源服务接入网设备或源基站)时，所述终端可在接收到感知服务器下发的感知测量任务 的情况下，发送所述第一信息给所述第一接入网设备，由此使得第一接入网设备获取第一信息。
或者，在所述第一接入网设备作为目标基站(也可理解为：目标服务接入网设备)时，所述终端可在由第三接入设备(如源基站)切换至所述第一接入网设备后，发送所述第一信息给所述第一接入网设备，由此使得第一接入网设备获取第一信息。
(12)所述第一接入网设备接收来自感知服务器的所述第一信息。
其中，在所述第一接入网设备作为服务基站时，所述感知服务器可在下发感知测量任务给所述终端的情况下，发送所述第一信息给所述第一接入网设备，由此使得第一接入网设备获取第一信息。
(13)所述第一接入网设备接收来自第三接入网设备的第一切换请求消息，所述第一切换请求消息包括所述第一信息。
其中，在所述第一接入网设备作为目标基站时，所述第三接入网设备作为源基站，所述第三接入网设备可在确定进行小区切换时，发送携带第一信息的第一切换请求消息给所述第一接入网设备，由此使得第一接入网设备获取第一信息。
需要注意，随着所述第一接入网设备在切换场景中承担的角色的不同，其服务频点可能发生改变，因此，所述第一接入网设备获取的第一信息(如感知辅助切换信息)可能不同或相同。例如，在所述第一接入网设备作为源基站时获取的第一信息，与所述第一接入网设备作为目标基站时获取的第一信息可以不同或相同，在此不做限制。
进一步，在一种实现方式中，所述第一信息可通过无线资源控制(Radio Resource Control，RRC)终端辅助信息消息(UE Assistance Information)的方式进行传输，即所述第一接入网设备接收RRC终端辅助信息消息，所述RRC终端辅助信息消息包括所述第一信息和/或所述第二信息。
或者，所述第一信息也可通过新引入的用于交互感知信息传输的RRC消 息进行传输，本实施例在此不做限制。
需要注意，本实施例对感知测量任务的实际类型不做限制。例如，按照感知目的的不同，所述感知测量任务可以包括两类，一类是感知用于辅助通信或增强通信性能，例如，基站通过跟踪设备的移动轨迹以提供更精确的波束赋形对准设备；另一类是与通信没有直接关系的感知，例如基站通过无线信号对天气情况进行监测、手机通过毫米波无线感知识别用户的手势等。
S220，所述第一接入网设备基于所述感知测量指示信息和/或感知辅助切换信息进行小区切换。
其中，所述第一接入网设备在基于所述感知测量指示信息和/或感知辅助切换信息进行小区切换时，可根据所述感知测量指示信息和/或感知辅助切换信息确定是否进行小区切换，或者，根据所述感知测量指示信息和/或感知辅助切换信息确定待切换的目标小区/目标频率，或者，根据所述感知测量指示信息和/或感知辅助切换信息确定进行目标小区的切换时机等，本实施例在此不做限制。
本实施例中，第一接入网设备通过获取包括感知测量指示信息和/或感知辅助切换信息的第一信息，并根据感知测量指示信息和/或感知辅助切换信息进行小区切换，由此，使得第一接入网设备获知所述终端正在执行感知测量任务，进而避免由于终端进行小区切换而导致无法确保感知测量业务的连续性的问题。
如图3所示，为本申请一示例性实施例提供的切换方法300的流程示意图，该方法300可以但不限于由第一接入网设备执行，具体可由安装于第一接入网设备中的硬件和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，第一接入网设备获取第一信息。
其中，所述第一信息包括感知测量指示信息和/或感知辅助切换信息，所述感知测量指示信息用于指示终端正在执行感知测量任务，所述感知辅助切 换信息用于辅助所述第一接入网设备对所述终端进行小区切换，所述第一接入网设备是所述终端的服务接入网设备。
可以理解，S310的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，所述第一接入网设备(如源基站)可基于感知辅助切换信息进行移动性管理，基于此，所述感知辅助切换信息可以包括以下(21)-(27)中的至少一项。
(21)感知信号的频点，所述感知信号用于所述终端执行感知测量任务。
(22)第一列表，所述第一列表包括至少一个候选频率，所述候选频率是所述终端进行小区切换时的候选目标频率。
其中，所述第一列表可以理解为能够支持感知特性的候选的切换目标频率列表。
可选的，所述第一列表中还可以包括目标频率的优先级信息，该优先级信息可以是隐式的优先级，例如，所述第一列表中的各候选频率可以按照由高到低或由低到高的优先级顺序排列。
(23)第二列表，所述第二列表包括至少一个候选小区，所述候选小区是所述终端进行小区切换时的候选目标小区。
其中，第一列表类似，所述第二列表可以理解为能够支持感知特性的候选的切换目标小区列表。
可选的，所述第二列表中还可以包括目标小区的优先级信息，该优先级信息可以是隐式的优先级，例如，所述第二列表中的各候选小区可以按照由高到低或由低到高的优先级顺序排列。
(24)第三列表，所述第三列表包括至少一个第一频率，所述第一频率是所述终端被禁止切换到的频率。
其中，所述第三列表可以理解为目标频率黑名单。也就是，当所述终端切换到第三列表中包括的任一第一频率后，可能由于收发机等能力的限制，会导致终端无法继续进行感知测量。
(25)第四列表，所述第四列表中包括至少一个第二小区，所述第二小区是所述终端被禁止切换到的小区。
其中，与所述第三列表类似，所述第四列表可以理解为目标小区黑名单。也就是，当所述终端切换到第四列表中包括的任一第二小区后，可能由于收发机等能力的限制，会导致终端无法继续进行感知测量。
(26)预估的感知数据上报的数据传输速率，所述感知数据与所述感知测量任务对应。其中，所述感知数据与所述感知测量任务对应可以理解为：所述终端在执行感知测量时得到的数据，即感知数据。
(27)感知服务器的地址。
其中，所述感知服务器的地址可以是所述感知服务器的物理地址或逻辑地址，本实施例对此不作限制。
可以理解，所述感知辅助切换信息包括的各信息内容可以由协议约定或高层配置实现，在此不做限制。
进一步，在相关技术中，如果终端和服务基站(如第一接入网设备)在一定的时间(不活动定时器(inactivity timer)时长，也可称作非激活定时器)内没有数据传输，那么为了省电，在inactivity timer超时后服务基站一般会让终端进入去活动态和/或空闲态。但是，考虑到终端进行感知测量需要一定的时间，即在这段时间内终端和服务基站之间可能没有数据传输，那么，如果服务基站(即源基站)让终端进入去活动态或空闲态，必然影响感知测量任务的执行，在此情况下，作为一种可选的实现方式，当第一接入网设备在通过第一信息获知终端正在执行感知测量任务后，可基于第一信息(如所述感知测量指示信息)控制所述终端维持在RRC连接态，即不使终端进入去活动态和/或空闲态。
当然，所述第一接入网设备控制所述终端维持在RRC连接态的步骤，可以包括以下(31)-(32)中任一项。
(31)停止不活动定时器。其中，“停止”也可以理解为不启动、暂停、 关闭、取消等。
(32)忽略不活动定时器的超时。也就是，所述第一接入网设备不停止不活动定时器，但是当不活动定时器超时时，不执行让终端进行状态迁移的操作，如不使终端进入去活动态和/或空闲态。
在前述实现方式中，所述第一接入网设备在获知终端正在执行感知测量任务后，通过控制所述终端维持在RRC连接态，从而使得终端在需要传输感知数据时，有效的节省了进入RRC连接态的流程，降低了时延，确保了无线通信的可靠性。
需要说明的是，当第一接入网设备在通过第一信息获知终端正在执行感知测量任务后，可基于第一信息控制所述终端维持在RRC连接态，(其可以作为独立的实施方案)，也可以结合后续的步骤一起实施。
S320，所述第一接入网设备基于所述感知测量指示信息和/或感知辅助切换信息进行小区切换。
可以理解，S320的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，请再次参阅图3所示，S320的实现过程至少可以包括如下S321-S324，内容如下。
S321，所述第一接入网设备基于所述感知辅助切换信息确定目标小区。
例如，当所述终端的服务小区信号变差时，源基站(即第一接入网设备)优先选择候选的切换目标频率列表(即第一列表)/目标小区列表(即第二列表)中的小区作为目标小区。又例如，当预估的感知数据上报的数据传输速率较大时，源基站优先选择负载较小的小区作为目标小区，以避免切换被拒绝或切换到目标小区后不能满足感知数据上报的数据传输速率要求。
此外，所述第一接入网设备除了可基于所述感知辅助切换信息确定目标小区之外，还可以基于所述感知辅助切换信息确定无线资源管理(radio resource management，RRM)测量配置信息。
例如，针对测量触发条件，将候选的或优先级高的切换目标频率列表(即 第一列表)中的频率/目标小区列表(即第二列表)中的小区的触发条件设置得更低，从而让其更容易触发测量上报。又例如，在测量配置里不携带目标频率黑名单(即第三列表)中的频率(即不配置UE测量这些频率)，将目标小区黑名单(即第四列表)作为测量黑名单。
S322，所述第一接入网设备向所述目标小区所属的第二接入网设备发送第二切换请求消息。
其中，所述第二切换请求消息中携带目标小区的相关信息，以使得所述第二接入网设备确定是否接受(或接纳)所述第二切换请求消息。
另外，考虑到为了在终端切换到第二接入网设备(即目标基站)后，在后续的切换中目标基站可以执行与源基站类似的操作，从而确保切换流程以及感知测量任务的顺利进行，所述第二接入网设备也可获取感知测量指示信息和/或感知辅助切换信息。
基于此，作为一种实现方式，所述目标基站获取感知测量指示信息和/或感知辅助切换信息的方式可以包括以下(41)-(42)中至少一项。
(41)所述第一接入网设备(即源基站)发送的所述第二切换请求消息中可以携带感知测量指示信息和/或感知辅助切换信息，由此使得目标基站获取感知测量指示信息和/或感知辅助切换信息。
(42)所述终端在切换到目标基站之后，向目标基站发送携带感知测量指示信息和/或感知辅助切换信息的第一信息，由此使得目标基站获取感知测量指示信息和/或感知辅助切换信息。
需要注意，由于终端由第一接入网设备(即源基站)切换至第二接入网设备(即目标基站)，服务频点可能发生了改变，因此，所述终端发送给第一接入网设备的第一信息携带的感知辅助切换信息可能不同于所述终端发送给第二接入网设备中携带的感知辅助切换信息，比如第一信息中的第一列表、第二列表可能不同。
S323，所述第一接入网设备接收所述第二接入网设备反馈的切换请求确 认消息。
其中，所述第二接入网设备在接受所述第二切换请求消息的情况下，向所述第一接入网设备反馈切换请求确认消息。
S324，所述第一接入网设备发送RRC重配置信息给所述终端。
其中，所述RRC重配置信息用于所述终端进行小区切换，如命令所述终端切换至目标小区，基于此，所述终端在接收到所述RRC重配置信息后，可切换至目标小区。
可选的，所述终端在切换至目标小区后，所述终端或所述第二接入网设备(与目标小区对应)可向感知服务器发送第三信息，所述第三信息可携带目标小区信息，如目标小区的标识或频点等信息，所述感知服务器根据所述目标小区信息确定更新的感知测量配置，或者确定感知测量任务适合或不适合所述目标小区；所述感知服务器发送第四信息给所述终端，其中，所述第四信息包括感知测量停止信息或更新的感知测量配置。
例如，如果所述感知服务器基于所述目标小区信息确定感知测量只适合在源基站/源小区进行测量，则感知服务器确定停止感知测量任务，然后向终端发送感知测量停止信息，即第四信息包括感知测量停止信息。
又例如，如果所述感知服务器基于所述目标小区信息确定更新的感知测量配置，那么，所述感知服务器向终端发送更新的感知测量配置，即第四信息包括更新的感知测量配置。
在此情况下，所述终端可以根据所述第四信息包括的感知测量停止信息停止执行感知测量任务，或，所述终端根据所述第四信息包括的更新的感知测量配置执行感知测量任务。
进一步，除前述切换过程之外，在一种实现方式中，所述第一接入网设备还可获取第二信息，所述第二信息用于指示所述终端执行的感知测量任务结束。也就是，当所述终端结束了感知测量任务时，所述终端或所述感知服务器可以向终端的当前服务基站(如源基站或目标基站)发送第二信息，该 第二信息用于指示终端结束了感知测量或感知测量任务。例如，所述第二信息可以为1个比特，当取值为0时表示终端结束了感知测量或感知任务。
可选的，与前述方法实施例200中所述的第一信息类似，所述第二信息也可以通过RRC终端辅助信息消息进行传输，如所述RRC终端辅助信息消息中包括所述第二信息。
本实施例中，源基站从终端或感知服务器获取到感知辅助切换信息，据此切换到合适的目标小区，进而在切换时确保了感知测量业务的连续性。
