Description

定位方法、装置、用户设备、网络设备、及定位管理设备 技术领域
本申请涉及通信技术领域，尤其涉及一种定位方法、装置、用户设备、网络设备、及定位管理设备。
背景技术
现有技术中存在多种定位技术以满足不同定位业务的需求，其中对于上行定位技术，主要是gNB(基站)/TRP(transmit-receive point，接收点)将SRS(Sounding Reference Signal，上行探测参考信号)配置信息发送给UE(User Equipment，用户设备)，UE根据SRS配置信息发送SRS，多个gNB/TRP可以测量UE发送的SRS，而LMF(Location Management Function定位管理功能)网元则可以向多个gNB/TRP请求测量结果。
但是经研究发现，现有技术中如果UE从一个小区移动到另外一个小区，此时LMF网元可能不知道UE移动到的新小区，从而不确定该向哪个gNB/TRP请求测量结果，并且新小区对应的gNB/TRP并没有UE的SRS配置信息，可能需要重新配置SRS配置信息，然后将新的SRS配置信息发送给UE，此时将可能导致定位业务中断。也就是说，目前的上行定位技术不能很好的支持定位业务连续性。
发明内容

在目前的定位技术中，用户设备110的服务小区由第一小区切换至第二小区时，可能会存在LMF网元不知道UE切换至第二小区，从而可能存在定位业务不连续性的问题，针对该技术问题，本申请实施例提供了一种定位方法。
可选的，本申请实施提供一种定位方法，该方法可以由用户设备即UE执行，该方法可以包括：
响应于UE的服务小区由第一小区切换至第二小区，根据上行定位参考信号配置信息发送参考信号。
可选的，第一小区指的是UE发生服务小区切换前的服务小区，第二小区指的是UE发生服务小区切换后的服务小区，其中，第一小区所对应的基站与第二小区所对应的基站可以为不同的基站。上行定位参考信号配置信息即UE用于发送定位参考信号的配置信息，可以包括但不限于UE发送参考信号时所需要的资源信息等，该资源信息可以指的是时域资源、或者频域资源、又或者为频域资源和时域资源等。

可选的，上述上行定位参考信号配置信息可以是在发生小区切换前由第一小区的网络设备(第一网络设备)向UE发送的上行定位参考信号配置信息(可以简称为配置1)，也可以是发生小区切换后由第二小区的网络设备(第二网络设备)向UE发送的上行定位参考信号配置信息(可以简称为配置2)，其中，配置2和配置1可以相同，也可以不同。例如，在上行定位参考信号配置信息为配置2时，该配置2可以与配置1相同，例如，在发生小区切换 时(可以是切换前、也可以是切换后)，第一网络设备可以将配置1发送给第二网络设备，第二网络设备可以根据配置1确定配置2，当然，配置2也可以是基于其他信息确定(将在下文中再展开说明)。
在本申请实施例中，在UE的服务小区由第一小区切换至第二小区，第一网络设备可以向第二网络设备发送用于指示UE正在进行定位业务的信息，相应的，第二网络设备可以向定位管理功能网元发送上行定位参考信号配置信息，以使向定位管理功能网元知晓UE在发生服务小区切换时所切换至的服务小区，而UE在切换至第二小区后，可以根据上行定位参考信号配置信继续发送参考信号，此时定位管理功能网元在知晓UE所切换至的服务小区后，可以根据上行定位参考信号配置信息向对应的网络设备获取参考信号的测量结果，保证了UE定位业务的连续性。
为了描述方便，在下文的实施例描述中，第一网络设备向UE发送的上行定位参考信号配置可以简称为配置1，第二网络设备向UE发送的上行定位参考信号可以简称为配置2。
在本申请可选的实施例中，根据上行定位参考信号配置信息发送参考信号，包括：
根据第一小区的网络设备向UE发送的第一上行定位参考信号配置信息发送参考信号。
其中，网络设备可以指的是小区的基站，也可以是接收点(即TRP)，本申请不限定。可选的，UE发送定位参考信号所依据的上行定位参考信号配置信息可以仍旧采用UE的服务小区发生切换前的小区(即第一小区)的网络设备所发送的上行定位参考信号配置信息(即第一上行定位参考信号配置信息，配置1)，也就是说，此时即使UE的服务小区发生切换，但是UE仍旧可以采用原来的上行定位参考信号配置信息发送参考信号。相应的，定位管理功能网元可以根据配置1向第二小区的网络设备获取参考信号的测量结果。
在本申请可选的实施例中，根据上行定位参考信号配置信息发送参考信号，包括：
接收第二小区的网络设备发送的第二上行定位参考信号配置信息；
根据第二上行定位参考信号配置信息发送参考信号。
可选的，在UE的服务小区发送切换后，切换后的服务小区(即第二小区)的网络设备可以向UE发送第二上行定位参考信号配置信息(即配置2)，UE接收到配置2)后，UE则可以根据接收到的配置2发送参考信号。
其中，该配置2可以是第二小区的网络设备重新生成的上行定位参考信号配置信息，也可以是第二网络设备根据配置1确定的配置信息等，其可以配置1相同。
在本申请可选的实施例中，该方法还包括：
接收第二小区的网络设备发送的第二上行定位参考信号配置信息；
根据上行定位参考信号配置信息发送参考信号，包括：
根据第一小区的网络设备向UE发送的第一上行定位参考信号配置信息和/或第二上行定位参考信号配置信息发送参考信号。
可选的，UE可以接收第二小区的网络设备发送的配置2，并且UE当前仍旧知晓配置1(即知晓服务小区切换前的上行定位参考信号配置信息)，此时UE可以根据网络设备和UE之间的协议约定，选择配置1和配置2中的任一种来发送参考信号。其中，UE具体选择哪种上行定位参考信号配置信息发送参考信号可以根据实际需求预先配置，本申请实施例不限定。例如，在配置1未激活时，UE可以根据配置2发送参考信号，在配置1激活时，可以根据配置1发送参考信号。
在本申请可选的实施例中，该方法还可以包括：
获取上行定位参考信号配置信息的激活指示信息；
根据上行定位参考信号配置信息发送参考信号，包括：
基于激活指示信息，根据上行定位参考信号配置信息发送参考信号。
其中，上行定位参考信号配置信息的激活指示信息用于指示激活上行定位参考信号配置信息。可选的，当上行定位参考信号配置信息的激活状态为未激活时，此时第二小区的网络设备可以向UE发送用于激活上行定位参考信号配置信息的激活指示信息，UE在接收到该激活指示信息时，根据上行定位参考信号配置信息发送上行定位参考信号。可以理解是，该上行定位参考信号配置信息可以为第一小区的网络设备向UE发送的第一上行定位参考信号配置信息，也可以是第二小区的网络设备发送的第二上行定位参考信号配 置信息。其中，第二上行定位参考信号配置信息可以是第二小区的网络设备基于从第一小区的网络设备接收到的第一上行定位参考信号配置信息和/或定位信息请求消息(第一小区的网络设备从定位管理功能网元接收到的)确定的，可以与第一上行定位参考信号配置信息相同，也可以不同。
其中，参考信号可以是不同类型的参考信号，如可以是周期性上行参考信号(如周期性SRS)、非周期性上行参考信号(如非周期SRS)或者半持续上行参考信号(如半持续SRS)。而对于周期性参考信号，网络设备无需向UE发送上行定位参考信号配置信息的激活指示信息，而对于非周期上行参考信号或半持续上行参考信号，网络设备则需要对上行定位参考信号配置信息进行单独激活，此时网络设备需要向UE发送激活指示消息，在该指示信息指示激活时，UE根据该上行定位参考信号配置信息进行参考信号的发送。
本申请实施还提供一种定位方法，该方法可以由第一网络设备执行，该网络设备指的是UE在发生服务小区切换前的服务小区的网络设备，即前文中的第一小区的网络设备，该方法可以包括：

可选的，第一网络设备可以向第二网络设备发送第一消息，以告知第二网络设备UE正在进行定位业务，而第一网络设备向第二网络设备发送第一消息的时机可以是UE的服务小区发生切换后，也可以是UE的服务小区发生切换前。
在本申请可选的实施例中，向第二网络设备发送第一消息，包括：
向UE在发生小区切换后所切换至的服务小区对应的网络设备发送第一消息；或者，
向UE的至少一个候选切换小区所对应的至少一个网络设备发送第一消息。
其中，第一网络设备可以在不同的时机向第二网络设备发送第一消息，而当第一网络设备向第二网络设备发送第一消息的时机不同时，第二网络设备所对应的网络设备也是不同的。可选的，当发送第一消息的时机在UE的服务小区发生切换后时，此时第一网络设备可以向UE在发生小区切换后所切换至的服务小区对应的网络设备发送第一消息，而当发送第一消息的时机 是UE的服务小区发生切换前时，则第一网络设备可以向UE在发生小区切换前UE的至少一个候选切换小区所对应的至少一个网络设备发送第一消息。

例如，当上行定位参考信号配置信息的激活状态指示信息所指示的激活状态为激活时，此时可以将第一消息中的上行定位参考信号配置信息(即配置1)直接作为新的上行定位参考信号配置信息(即配置2)，当然也可以根据上行定位参考信号配置信息和/或定位信息请求消息重新确定新的上行定位参考信号配置信息、或者根据协议约定确定具体是生成新的上行定位参考信号配置信息，还是将配置1作为配置2，本申请实施例对此不限定。
可选的，第二网络设备接收到第一网络设备发送的第一消息后，可以知晓UE正在进行定位业务的信息，并且可以像向定位管理功能网元发送第二消息用于指示UE的服务小区为第二网络设备对应的小区的指示信息，以使定位管理功能网元知晓U E所切换至的服务小区，然后根据第二网络设备发送的上行定位参考信号配置信息，获取UE发送的参考信号的测量结果。
在本申请实施例中，在UE的服务小区由第一小区切换至第二小区时， 第一网络设备可以向第二网络设备发送用于指示UE正在进行定位业务的信息，相应的，第二网络设备可以向定位管理功能网元发送指示信息，以使向定位管理功能网元知晓UE在发生服务小区切换时所切换至的服务小区，进而定位管理功能网元向所切换至的服务小区对应网络设备获取定位参考信号的测量结果，保证了UE定位业务的连续性。
如图2所示，本申请实施还提供一种定位方法，该方法可以由第二网络设备执行，该第二网络设备指的是UE在发生服务小区切换时，所切换至的服务小区的网络设备，该方法可以包括：

可选的，当UE进行服务小区切换，如从第一小区切换至第二小区时，第一小区的网络设备(即第一网络设备)可以向第二小区的网络设备(第二网络设备)发送第一消息，以告知第二网络设备UE正在进行定位业务。而当UE的服务小区从第一小区切换至第二小区时，定位管理功能网元并不知晓UE的当前服务小区为第二小区，因此，第二网络设备在接收到第一消息之后，为了保证UE定位业务的连续性，还可以向定位管理功能网元发送相应的指示信息，以使向定位管理功能网元知晓UE的服务小区由第一小区切换至了第二小区，从而可以向第二小区的网络设备获取UE所发送的定位参考信号的测量结果，从而保证了UE定位业务的连续性。
在本申请可选的实施例中，第一消息还可以包括以下信息中的至少一项：
第一上行定位参考信号配置信息；
第一上行定位参考信号配置信息的激活状态指示信息；
定位信息请求消息；

向UE发送第二上行定位参考信号配置信息。
可选的，当第二网络设备生成第二上行定位参考信号配置信息(即配置2)后，可以向UE发送该配置2，以使UE根据该配置2发送参考信号。其中，配置2和配置1可以相同，也可以不同，例如，在上行定位参考信号配置信息为配置2时，该配置2可以与配置1相同，例如，在发生小区切换时(可以是切换前、也可以是切换后)，第一网络设备可以将配置1发送给第二网络设备，第二网络设备可以根据配置1确定配置2，当然，配置2也可以是基于其他信息确定等。

在本申请可选的实施例中，指示消息或第二消息还包括第二上行定位参考信号配置信息。
可选的，第二网络设备可以将第二上行定位参考信号配置信息直接作为指示消息发送至定位管理功能网元，由于该第二上行定位参考信号配置是第二网络设备发送至UE的上行定位参考信号配置；相应的，当定位管理功能网元接收到该作为指示信息的第二上行定位参考信号配置信息时即可以知晓UE的服务小区为第二网络设备对应的小区，并且可以基于该第二上行定位参考信号配置信息向对应的网络设备获取UE发送的定位参考信号的测量结果。
可选的，第二网络设备还可以在向定位管理功能网元发送用于告知UE的服务小区为第二网络设备对应的小区的指示信息的同时，单独将第二网络设备发送至UE的第二上行定位参考信号配置信息(即配置2)发送至向定位管理功能网元，以使向定位管理功能网元可以基于该第二上行定位参考信号配置信息获取UE发送的定位参考信号的测量结果。
