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，所描述的实施例仅仅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。
图1是根据本公开的实施例示出的一种请求发送方法的示意流程图。本实施例所示的方法可以适用于核心网，所述核心网包括但不限于LMF(Location Management Function，定位管理功能)、AMF(Access and Mobility Management Function，接入与移动性管理)等功能，所述方法在一个实施例中，可以具体适用于LMF。
所述核心网包括但不限于5G核心网、6G核心网，所述核心网可以与基站通信，例如向基站发送定位信息的获取请求，基站接收到获取请求后，可以确定终端的信道探测参考信号SRS配置，并将SRS配置发送给核心网，还可以将SRS配置发送给终端，以指示终端发送SRS的资源。
其中，SRS为终端向基站发送的参考信号，可以用于对终端进行上行定位，可以称之为positioning SRS，UL positioning SRS
核心网可以将接收到的SRS配置发送给一个或多个基站，该一个或多个基站可以基于SRS配置接收终端发送的SRS，并对终端发送SRS的配置进行测量，进而将测量结果发送给核心网，核心网可以基于多个(例如两个或两个以上)所述测量结果确定终端的位置，所述终端包括但不限于手机、平板电脑、可穿戴设备、工业传感器、物联网设备等电子设备。
如图1所示，所述请求发送方法可以包括以下步骤：
在步骤S101中，向终端当前所在小区对应的第一基站发送获取所述终端的定位信息的第一获取请求；
在步骤S102中，响应于根据所述第一获取请求的响应信息确定所述终端将要切换小区，向所述终端将要切换到的至少一个目标小区对应的至少一个基站发送获取所述终端的定位信息的第二获取请求。
在一个实施例中，核心网在需要确定终端的位置时，可以先确定终端当前所在的小区(例如服务小区)对应的第一基站，然后向第一基站发送第一获取请求，用于获取所述第一基站确定的所述终端的第一SRS配置。
在一个实施例中，核心网可以通过NRPPa(NR Positioning Protocol A，NR定位协议A)消息携带所述第一获取请求发送给所述第一基站，所述第一获取请求例如可以是所述NRPPa消息中的位置信息请求(positioning information request)消息。
类似地，核心网可以通过NRPPa携带所述第二获取请求发送给所述至少一个基站，所述第二获取请求例如可以是所述NRPPa消息中的位置信息请求消息。
第一基站在接收到第一获取请求后，可以向核心网发送第一获取请求的响应信息(positioning information response)，并且可以确定所述终端是否将要切换小区。
例如终端可以测量第一基站的邻基站的信息，包括但不限于信号的相关信息，例如RSRP(Reference Signal Receiving Power，参考信号接收功率)、RSRQ(Reference Signal Receiving Quality，参考信号接收质量)等，然后将测量到的信息发送给第一基站，第一基站可以根据终端测量到的信息确定终端是否将要切换小区。
例如基站可以对终端进行移动状态估计(Mobility State Estimation，简称MSE)，进而根据移动状态估计结果确定终端是否将要离开当前所在小区，从而产生切换小区的动作。
需要说明的是，满足切换条件的小区可以存在多个，因此第一基站确定终端将要切换到的小区也可以是多个，并且多个小区可以对应一个基站，也可以对应多个基站。
第一基站在确定终端将要切换小区的情况下，可以在所述响应信息中添加指示信息，用于向所述核心网指示所述终端将要切换小区，以及所述终端将要可能切换到 的至少一个目标小区对应的至少一个基站，从而使得核心网确定终端将要切换小区，以及终端将要切换到的至少一个目标小区对应的至少一个基站。
据此，核心网可以向所述终端将要切换到的至少一个目标小区对应的至少一个基站发送获取所述终端的定位信息的第二获取请求，从而使得所述至少一个基站得知核心网需要对所述终端进行定位。那么在所述终端完成切换小区后，切换后的小区对应的基站可以立即向终端发送SRS配置，接收终端发送的SRS，并对终端发送的SRS进行测量得到测量结果，进而发送给核心网，确保核心网可以及时地获取到所述测量结果，进而及时地基于所述测量结果确定终端的位置。
图2是根据本公开的实施例示出的另一种请求发送方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，从所述第一基站接收第一基站确定的所述终端的第一SRS配置；从所述至少一个基站接收所述至少一个基站确定的所述终端的第二SRS配置。
在一个实施例中，第一基站在接收到第一获取请求后，可以确定终端的SRS资源，并根据该资源确定第一SRS配置，然后将第一SRS配置发送给核心网，例如可以携带在第一获取请求的响应信息中发送给核心网。
在一个实施例中，所述至少一个基站在接收到第二获取请求后，可以分别确定终端的SRS资源，并根据该资源确定第二SRS配置，然后将第二SRS配置发送给核心网，例如可以携带在第二获取请求的响应信息中发送给核心网。例如至少一个基站包括gNB2和gNB3，那么gNB2可以确定终端的第二SRS配置并发送给核心网，gNB3可以确定终端的第二SRS配置发送给核心网，而gNB2确定的第二SRS配置和gNB3确定的第二SRS配置可以不同。
图3是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图3所示，所述方法还包括：
在步骤S301中，响应于确定所述终端已切换到所述至少一个基站中第二基站对应的小区，至少向所述第二基站发送请求信息，其中，所述请求信息用于请求获取所述第二基站对所述终端发送的信道探测参考信号SRS的测量结果；
在步骤S302中，根据至少所述第二基站发送的所述测量结果确定所述终端的位置。
在一个实施例中，核心网可以通过AMF确定终端从第一基站对应的小区切换 到第二基站对应的小区，从而至少向第二基站发送请求信息，以请求获取第二基站对终端发送的SRS的测量结果，进而基于至少来自第二基站的测量结果确定终端的位置。
在一个实施例中，所述测量结果包括但不限于接收到SRS的时间、角度、信号强度等信息。另外，核心网除了可以根据所述测量结果确定终端的位置，还可以获取第二基站确定的所述终端的第二SRS配置，第二SRS配置可以指示终端向第二基站发送SRS的资源，核心网可以根据配置信息和所述测量结果来确定终端的位置。上述两种确定位置的方式，具体可以根据定位算法的需要进行选择。
需要说明的是，核心网可以仅向第二基站发送请求信息，还可以向第二基站的邻基站发送请求信息，具体可以根据需要选择，以下通过两个实施例进行示例性说明。
可选地，所述请求信息中携带有所述终端的标识。
在一个实施例中，在发送给第二基站的请求信息中，可以携带有所述终端的标识，从而使得第二基站根据所述标识确定所述终端，进而对所述终端配置SRS和对其发送的SRS进行测量。
图4是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图4所示，所述至少向所述第二基站发送请求信息包括：
在步骤S401中，向所述第二基站发送请求信息。
在一个实施例中，核心网可以仅向第二基站发送请求信息，例如第二基站上设置多个(两个或两个以上)TRP(Transmission Reception Point，传输接收点)，每个TRP都可以接收终端发送的SRS，并对终端发送SRS进行测量，从而基于每个TRP都可以得到一个测量结果，每个TPR按照相同的配置信息接收终端发送的SRS，不同TPR得到的测量结果可以不同。
那么在第二基站上设置有多个TRP的情况下，第二基站可以得到多个测量结果。基于所述请求信息，第二基站可以将多个TRP分别得到的测量结果发送给核心网，以供核心网根据接收到的多个测量结果确定终端的位置。
图5是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图4所示，所述至少向所述第二基站发送请求信息包括：
在步骤S501中，向所述第二基站以及所述第二基站的至少一个邻基站发送请求信息。
在一个实施例中，所述至少一个基站在接收到第二获取请求后，可以分别确定终端对应基站的SRS的资源，并根据该资源确定第二SRS配置，然后将第二SRS配置发送给核心网，例如可以携带在第二获取请求的响应信息中发送给核心网。例如至少一个基站包括gNB2和gNB3，那么gNB2可以确定终端对应gNB2的第二SRS配置并发送给核心网，gNB3可以确定终端对应gNB3的第二SRS配置发送给核心网，而gNB2可以确定第二SRS配置和gNB3确定的第二SRS配置可以不同。
核心网可以向第二基站，以及第二基站的至少一个邻基站发送请求信息，通过请求信息请求获取第二基站以及邻基站对终端发送的SRS的测量结果，终端可以向第二基站以及所述邻基站发送SRS，从而第二基站可以对终端发送的SRS进行测量得到测量结果，第二基站的邻基站也可以对终端发送的SRS进行测量得到测量结果，进而第二基站和第二基站的邻基站可以将得到的测量结果发送至核心网，以供核心网根据接收到的多个测量结果确定终端的位置。
可选地，在所述请求信息中携带有所述第二基站确定的所述终端的第二SRS配置。
在一个实施例中，第二基站可以确定第二SRS配置，用于指示终端向第二基站发送SRS的资源(包括时域资源和频域资源)，并且第二基站可以将所述第二SRS配置发送给核心网。
核心网在发送的请求信息中可以携带所述第二SRS配置，那么接收到所述请求信息的邻基站可以从所述请求信息中获取所述第二SRS配置，从而可以按照所述第二SRS配置接收所述终端发送的SRS，进而实现对终端发送SRS的测量。
而通过向第二基站发送第二SRS配置，使得接收到所述第二SRS配置的第二基站，可以基于所述第二配置信息接收所述终端发送的SRS，据此，可以不必向第二基站发送所述终端的标识，即可使得第二基站确定接收所述终端发送的SRS。
图6是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图5所示，所述方法还包括：
在步骤S601中，将所述至少一个基站确定的所述终端的SRS的配置发送给所述第一基站。
在一个实施例中，所述至少一个基站在接收到第二获取请求后，可以分别确定终端对应基站的SRS的资源，并根据该资源确定第二SRS配置，然后将第二SRS配 置发送给核心网，例如可以携带在第二获取请求的响应信息中发送给核心网。
例如至少一个基站包括gNB2和gNB3，那么gNB2可以确定终端对应gNB2第二SRS配置并发送给核心网，gNB3可以确定终端对应gNB3的第二SRS配置发送给核心网，而gNB2可以确定第二SRS配置和gNB3确定的第二SRS配置可以不同。
例如对于第二基站而言，第二基站可以确定终端的第二SRS配置，通过第二SRS配置指示终端发送SRS的资源，而第二基站作为所述至少一个基站中的基站，可以将第二SRS配置发送给核心网，该动作可以在终端完成小区切换之前，或者在终端进行小区切换过程中执行。
进而核心网可以将第二SRS配置发送给第一基站，第一基站可以将第二SRS配置发送给所述终端，从而在终端切换到第二基站之前，即可根据第二SRS配置确定对应第二基站发送SRS的资源，第二基站可以不必再次向终端发送第二SRS配置，以便终端尽快发送SRS，使得第二基站尽快完成测量，从而降低定位时延。
可选地，所述第二获取请求中还包括所述第一基站确定的所述终端的第一SRS配置。
在一个实施例中，第一基站确定终端的第一SRS配置，通过第一SRS配置指示终端向第一基站发送SRS的资源，并且第一基站还可以将第一SRS配置发送给核心网，该动作可以在终端完成小区切换之前，或者在终端进行小区切换过程中执行。
进而核心网可以将第一SRS配置发送给第二基站，例如携带在第二获取请求中发送给第二基站，从而使得第二基站也可以根据第一SRS配置接收基站发送的SRS，并进行测量，无需再向终端发送配置信息，有利于降低第二基站的负荷，以便第二基站尽快接收终端发送的SRS。
图7是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图7所示，所述方法还包括：
在步骤S701中，向所述至少一个基站中所述第二基站以外的其他基站发送释放指示信息，其中，所述释放指示信息用于指示所述其他基站释放为所述终端配置的SRS资源。
在一个实施例中，在终端未切换到第二基站之前，核心网仅能确定终端将要切换到所述至少一个基站，所以会向所述至少一个基站发送第二获取请求，至少一个基站中的每个基站接收到第二获取请求后，都会为终端配置SRS资源。
但是终端最终只会切换到至少一个基站中某个基站对应的小区，也即第二基站对应的小区，那么至少一个基站中第二基站以外其他基站为终端配置的SRS资源，终端就用不到了，因此核心网可以向所述其他基站发送释放指示信息，以指示其他基站释放为所述终端配置的SRS资源，减少对通信资源不必要的占用。
图8是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图8所示，所述方法还包括：
在步骤S801中，响应于所述第二基站确定的所述终端的第二SRS配置为非周期或半持续SRS，向所述第二基站发送激活指示信息，其中，所述激活指示信息用于指示所述第二基站激活所述终端发送SRS。
在一个实施例中，终端基于第二SRS配置发送SRS的方式包括但不限于周期发送、非周期发送和半持续发送，其中，对于周期发送的情况，终端可以周期性发送SRS，而对于非周期和半持续发送SRS的情况，终端需要基站激活才能发送SRS。
因此，对于终端非周期或半持续发送SRS的情况，核心网可以向第二基站发送激活指示信息，从而使得第二基站激活终端发送SRS，进而得到所述测量结果以发送至核心网。
图9是根据本公开的实施例示出的一种响应信息发送方法的示意流程图。本实施例所示的方法可以适用于第一基站，例如上述请求发送方法中的第一基站，所述第一基站包括但不限于5G基站、6G基站，所述第一基站可以与终端和核心网通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、工业传感器、物联网设备等电子设备。

在步骤S901中，接收核心网发送的获取终端的定位信息的第一获取请求；
在步骤S902中，响应于确定所述终端将要切换小区，向所述核心网发送所述第一获取请求的响应信息，其中，所述响应信息用于向所述核心网指示所述终端将要切换到的至少一个目标小区对应的至少一个基站。
在一个实施例中，在需要确定终端的位置时，核心网可以先确定终端当前所在的小区(例如服务小区)对应的第一基站，然后向第一基站发送第一获取请求，用于获取所述第一基站确定的所述终端的第一SRS配置。
在一个实施例中，核心网可以通过NRPPa消息携带所述第一获取请求发送给所述第一基站，所述第一获取请求例如可以是所述NRPPa消息中的位置信息请求消息。
第一基站在接收到第一获取请求后，可以向核心网发送第一获取请求的响应信息，响应信息可以包括上述实施例中的第一SRS配置，并且可以确定所述终端是否将要切换小区。
例如终端可以检测第一基站的邻基站的信息，包括但不限于信号的相关信息，例如RSRP、RSRQ等，然后将检测到的信息发送给第一基站，第一基站可以根据终端检测到的信息确定终端是否将要切换小区。
例如基站可以对终端进行移动状态估计，进而根据移动状态估计结果确定终端是否将要离开当前所在小区，从而产生切换小区的动作。
第一基站在确定终端将要切换小区的情况下，可以在所述响应信息中添加指示信息，用于向所述核心网指示所述终端将要切换小区，以及所述终端将要可能切换到的至少一个目标小区对应的至少一个基站。
据此，使得核心网可以确定终端将要切换小区，以及终端将要切换到的至少一个目标小区对应的至少一个基站。进而核心网可以向所述终端将要切换到的至少一个目标小区对应的至少一个基站发送获取所述终端的定位信息的第二获取请求，从而使得所述至少一个基站得知核心网需要对所述终端进行定位。那么在所述终端完成切换小区后，切换后的小区对应的基站可以接收终端发送的SRS，并对终端发送的SRS进行测量得到测量结果，进而发送给核心网，确保核心网可以及时地获取到所述测量结果，进而及时地基于所述测量结果确定终端的位置。

在一个实施例中，在所述终端切换到第二基站对应小区的情况下，第二基站可以向终端发送第二SRS配置，通过第二SRS配置指示终端发送SRS的资源，并且第二基站还可以将第二SRS配置发送给核心网，该动作可以在终端完成小区切换之前，或者在终端进行小区切换过程中执行。
进而核心网可以将第二SRS配置发送给第一基站，第一基站可以将第二SRS配置发送给所述终端，从而在终端切换到第二基站之后，即可根据第二SRS配置发送SRS，第二基站可以不必再次向终端发送第二SRS配置，以便终端尽快发送SRS，从而使得第二基站尽快完成测量。

在一个实施例中，第二基站可以向终端发送第二SRS配置，通过第二SRS配置指示终端发送SRS的资源，并且第二基站还可以将第二SRS配置发送给核心网，该动作可以在终端完成小区切换之前，或者在终端进行小区切换过程中执行。
进而核心网可以将第二SRS配置发送给第一基站，第一基站可以将第二SRS配置发送给所述终端，从而在终端在切换到第二基站之后，即可根据第二SRS配置确定发送SRS的资源，第二基站可以不必再次向终端发送第二SRS配置，以便终端尽快发送SRS，从而使得第二基站尽快完成测量。

在一个实施例中，核心网可以向第二基站发送第二SRS配置，使得接收到所述第二SRS配置的第二基站，可以基于所述第二配置信息接收所述终端发送的SRS，据此，可以不必向第二基站发送所述终端的标识供第二基站确定所述终端，即可使得第二基站确定接收所述终端发送的SRS。
图14是根据本公开的实施例示出的又一种定位信息获取方法的示意流程图。如图14所示，所述方法还包括：
在步骤S1401中，从所述核心网接收所述第一基站确定的所述终端的第一SRS配置；

进而核心网可以将第一SRS配置发送给第二基站，从而使得第二基站也可以根据第一SRS配置确定所述第二SRS配置，例如将第一SRS配置作为第二SRS配置，从而基于第一SRS配置接收终端发送的SRS，并进行测量，无需再向终端发送配置信息，有利于降低第二基站的负荷，以便第二基站尽快接收终端发送的SRS。
图15是根据本公开的实施例示出的一种终端、第一基站、第二基站和核心网交互的示意图。
如图15所示，核心网在需要确定终端的位置时，可以先确定终端当前所在的小区对应的基站，例如为图15所示的gNB1，核心网可以通过LMF向gNB1发送第一获取请求，所述第一获取请求可以携带在NRPPa消息中，具体可以是NRPPa消息中的位置信息请求消息。
gNB1可以为终端配置定位参考信号，并向核心网发送第一获取请求的响应信息，还可以确定终端是否将要切换小区，第一基站在确定终端将要切换小区的情况下，可以在所述响应信息中添加指示信息，用于向所述核心网指示所述终端将要切换小区，以及所述终端将要可能切换到的至少一个目标小区对应的至少一个基站。例如至少一个基站包括两个基站：gNB2和gNB3。
核心网在确定终端将要切换到gNB2和gNB3后，可以向gNB2和gNB3发送第二获取请求，所述第二获取请求携带在NRPPa消息中，具体可以是NRPPa消息中的位置信息请求消息。
gNB2接收到第二获取请求后，可以确定SRS配置2，然后将SRS配置2发送给核心网，还可以将基于位置信息请求消息将SRS配置2以外的信息发送给核心网，具体基于位置信息请求消息所请求的内容而定。
类似地，gNB3接收到第二获取请求后，可以确定SRS配置3，然后将SRS配置3发送给核心网，还可以将基于位置信息请求消息将SRS配置3以外的信息发送给核心网，具体基于位置信息请求消息所请求的内容而定。
例如，终端切换小区可以是从gNB1对应的小区切换到了gNB2对应的小区，核心网中的AMF可以确定终端切换到了gNB2对应的小区，从而向LMF告知终端切 换到了gNB2对应的小区。
gNB2可以为终端配置定位参考信号以及将SRS配置2发送给终端，以使终端根据SRS配置2所指示的资源向基站发送SRS，并且gNB2可以对终端发送的SRS进行测量，以得到测量结果。
核心网还可以向gNB3发送释放指示信息，指示gNB3释放SRS配置3所对应的资源。

据此，gNB1在确定核心网需要对终端进行定位，而终端需要切换小区的情况下，可以告知核心网终端将要切换到的小区gNB2和gNB3，从而使得核心网可以向gNB2和gNB3发送第二获取请求，gNB2和gNB3可以为终端配置上行传输SRS的资源。而在终端切换到gNB2对应的小区后，核心网可以至少向gNB2(还可以向gNB2的邻基站)发送请求信息，以使gNB2接收终端发送的SRS，并将对SRS测量得到的测量结果发送给核心网，以供核心网确定终端的位置。
