根据本公开实施例的第六方面，提出一种定位信息接收装置，适用于终端，所述装置包括：
信令接收模块，被配置为接收基站指示终端进入非连接态的信令；
信息获取模块，被配置为从所述信令中获取定位信息。
根据本公开实施例的第七方面，提出一种通信装置，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为执行上述定位信息发送方法，和/或定位信息接收方法。
根据本公开实施例的第八方面，提出一种计算机可读存储介质，用于存储计算机程序，所述程序被处理器执行时实现上述定位信息发送方法，和/或定位信息接收方法中的步骤。
根据本公开的实施例，核心网不仅可以将定位信息发送至基站，还可以向基站发送第一指示信息，使得基站可以根据第一指示信息确定定位信息供终端在非连接态使用，而不是在连接态使用，从而可以通过指示终端进入非连接态的信令携带定位信息发送给终端，而不会使用下行信息传输信令携带定位信息。
据此，使得基站可以明确对于接收到的定位信息，是否使用指示终端进入非连接态的信令携带以发送给终端，避免基站不能确定是通过下行信息传输信令携带定位信息发送给终端，还是通过指示终端进入非连接态的信令携带定位信息发送给终端，避免发送定位信息出现问题。

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。
为了实现对非连接态终端的定位，一种存在可行性的方案是通过无线资源控制释放(RRC release)信令携带定位辅助信息发送给终端。
但是问题在于，若可以通过无线资源控制释放信令携带定位辅助信息发送给终端，那么对于基站而言，基站既能够通过下行信息传输信令携带定位辅助信息发送给终端，又能通过无线资源控制释放信令携带定位辅助信息发送给终端。
在这种情况下，基站接收到的核心网发送的定位辅助信息后，并不知道应该通过下行信息传输信令携带定位辅助信息发送给终端，还是通过无线资源控制释放信令携带定位辅助信息发送给终端，容易导致发送定位辅助信息出现问题。
图1是根据本公开的实施例示出的一种定位信息发送方法的示意流程图。本实施例所示的定位信息发送方法可以适用于基站，所述基站包括但不限于4G基站、5G基站、6G基站。所述基站可以与核心网以及作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
在一个实施例中，所述终端可以是后续任一实施例所述定位信息接收方法所适用的终端。所述核心网可以是后续任一实施例所述的定位信息发送方法所适用的核心网。
如图1所示，所述定位信息发送方法可以包括以下步骤：
在步骤S101中，接收核心网发送的定位信息；
在步骤S102中，响应于接收到所述核心网发送的第一指示信息，通过用于指示终端进入非连接态的信令携带所述定位信息发送至终端，其中，所述第一指示信息指示所述定位信息供所述终端在非连接态使用。
在一个实施例中，核心网可以向基站发送定位信息，其中，定位信息包括但不限于以下至少之一：
定位辅助信息、定位请求信息。
其中，定位辅助信息中携带的内容包括但不限于定位参考信号的配置信息，终端可以根据该配置信息接收定位参考信号；定位请求信息中携带的内容包括但不限于定位请求，用于向终端请求位置信息、对定位参考信号的测量结果等。
在一个实施例中，所述信令包括以下至少之一：
无线资源控制释放信令、无线资源控制挂起信令。
在一个实施例中，所述非连接态包括以下至少之一：
空闲态、非激活态。
基于所述信令的不同，所述非连接态也可以有所不同。例如信令是无线资源控制释放(RRC release)信令，那么第一指示信息指示所述定位信息供所述终端在空闲(idle)态使用；例如信令是无线资源控制挂起(RRC suspend)信令，那么第一指示信息指示所述定位信息供所述终端在非激活(inactive)态使用。
根据本公开的实施例，核心网不仅可以将定位信息发送至基站，还可以向基站发送第一指示信息，使得基站可以根据第一指示信息确定定位信息供终端在非连接态使用，而不是在连接态使用，从而可以通过指示终端进入非连接态的信令携带定位信息发送给终端，而不会使用下行信息传输信令携带定位信息。
据此，使得基站可以明确对于接收到的定位信息，是否使用指示终端进入非连接态的信令携带以发送给终端，避免基站不能确定是通过下行信息传输信令携带定位信息发送给终端，还是通过指示终端进入非连接态的信令携带定位信息发送给终端，避免发送定位信息出现问题。
在一个实施例中，核心网在定位信息供连接态的终端使用的情况下，可以不额外发送指示信息，只发送定位信息给终端，基站即可确定定位信息供连接态的终端使用，进而通过下行信息传输信令携带定位信息发送给终端；或者核心网在定位信息供连接态的终端使用的情况下，也可以额外发送指示信息，指示发送给基站的定位信息供连接态的终端使用，进而基站可以通过下行信息传输信令携带定位信息发送给终端。
需要说明的是，终端可以与网络侧约定，或者由协议规定，终端在进入非连接态后，才会使用携带在所述信令中的定位信息进行定位流程，而在连接态下，终端即使接收到了所述信令，也不会使用携带在所述信令中的定位信息进行定位流程。
例如所述信令为无线资源控制释放信令，那么终端会在进入空闲态后使用所述 定位信息进行定位流程；例如所述信令为无线资源控制挂起信令，那么终端会在进入非连接态后使用所述定位信息进行定位流程。
另外，核心网向基站发送的定位信息，可以是新定义的定位信息，以便与已有的供连接态的终端使用的定位信息区分开，例如已有的供连接态的终端使用的定位信息包括LPP provide assistance data和LPP request location information，那么新定义的定位信息可以包括LPP provide assistance data1和LPP request location information1。
在一个实施例中，所述第一指示信息可以携带在NR定位协议消息中。
在定位过程中，核心网主要可以向基站发送两种信息，一种是LPP PDU，另一种是NR定位协议消息，由于LPP PDU是非接入层信息，基站一般不能解析得到其中的内容，而针对NR定位协议消息，基站可以解析得到其中的内容，因此通过NR定位协议消息携带第一指示信息，可以确保基站能够解析NR定位协议消息得到其中的第一指示信息。
图2是根据本公开的实施例示出的另一种定位信息发送方法的示意流程图。如图2所示，在一些实施例中，所述接收核心网发送的定位信息包括：
在步骤S201中，接收所述核心网发送的LTE(Long Term Evolution，长期演进)定位协议的协议数据单元LPP PDU，所述LPP PDU中携带有所述定位信息；
其中，所述第一指示信息用于指示所述LPP PDU供所述终端在非连接态使用。
在一个实施例中，核心网可以通过LPP PDU携带定位信息发送至基站，在这种情况下，由于LPP PDU是非接入(NAS)层信息，基站并不会解析其中的内容，也即基站一般情况下仅知道接收到核心网发送的LPP PDU，而不知道LPP PDU中携带的是定位信息，所以核心网可以通过第一指示信息指示发送的LPP PDU是供终端在非连接态使用的，那么基站可以将包含所述定位信息的LPP PDU携带在所述信令中发送给终端。
图3是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图3所示，在一些实施例中，所述通过用于指示终端进入非连接态的信令携带所述定位信息发送至终端包括：
在步骤S301中，通过所述信令携带LPP PDU发送至终端，在所述信令携带的LPP PDU中携带有所述定位信息。
在一个实施例中，由于LPP PDU是非接入层信息，基站接收到LPP PDU后，可以将LPP PDU透传至终端，也即一般情况下基站不对LPP PDU进行解析去获取其中的定位信息，而是直接将接收到的LPP PDU携带在所述信令中发给终端。
图4是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图4所示，在一些实施例中，所述接收核心网发送的定位信息包括：
在步骤S401中，接收所述核心网发送的NR(New Radio，新空口)定位协议消息(例如NRPPa消息)；
在步骤S402中，从所述NR定位协议消息中获取所述定位信息；
其中，所述第一指示信息指示所述定位信息供所述终端在非连接态使用。
在一个实施例中，核心网可以通过NR定位协议消息携带定位信息发送至基站，在这种情况下，由于基站可以解析NR定位协议消息的内容得到定位信息，那么核心网可以通过第一指示信息指示定位信息是供终端在非连接态使用的，那么基站可以将从NR定位协议消息得到的定位信息携带在所述信令中发送给终端。
图5是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图5所示，在一些实施例中，所述通过用于指示终端进入非连接态的信令携带所述定位信息发送至终端包括：
在步骤S501中，通过所述信令携带所述定位信息发送至终端。
在一个实施例中，基站接收到NR定位协议消息后，可以解析NR定位协议消息以获取其中的定位信息，进而将从NR定位协议消息得到的定位信息携带在所述信令中发给终端。
需要说明的是，核心网发送给基站的携带定位信息的NR定位协议消息，可以是指定终端专属的，例如可以在NR定位协议消息中携带指定终端的标识，以使基站可以根据标识确定将定位信息发送至指定终端。
图6是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图6所示，在一些实施例中，所述方法还包括：
在步骤S601中，响应于所述终端不进入非连接态，向所述终端发送第二指示信息，用于指示向所述终端发送定位信息失败。
在一个实施例中，虽然基站可以通过指示终端进入非连接态的信令携带所述定 位信息发送至终端，但是所述信令是在终端将要进入非连接态才发送给终端的，若终端不进入非连接态，那么基站就不能向终端发送信令，也就不能通过所述信令携带定位信息发送给终端。
在这种情况下，基站可以向终端发送第二指示信息，以指示终端向终端发送定位信息失败，从而使得终端确定基站原本是要给终端发送定位信息的，但是出于某些原因发送定位信息失败，进而终端在需要获取定位信息时，可以通过与基站、核心网等网络侧设备通信，重新获取定位信息。
图7是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图7所示，在一些实施例中，所述向所述终端发送第二指示信息包括：
在步骤S701中，响应于所述终端切换到其他小区，向所述终端发送第二指示信息。
在一个实施例中，基站可以在确定终端切换到其他小区时，向终端发送第二指示信息。其中，终端切换到其他小区，可以是指终端发起了切换到其他小区的流程，但是仍驻留在所述基站。
在确定终端切换到其他小区时，说明终端离开所述基站的小区驻留到其他基站的小区，那么基站就不能通过所述信令携带定位信息发送给终端了，因此可以在这种情况下，基站才完全确定向终端发送定位信息失败，并通过第二指示信息指示终端向终端发送定位信息失败。
而在终端不切换到其他小区的情况下，即使终端不进入非连接态，由于终端仍然驻留在所述基站的小区，所以所述基站后续仍有机会向终端发送所述信令，因此可以不确定为发送定位信息失败，从而不向终端发送第二指示信息。
在一个实施例中，所述定位信息携带在LPP PDU中，所述第二指示信息用于指示向所述终端发送LPP PDU失败，或者用于指示向所述终端发送定位信息失败。
在定位信息携带在LPP PDU中的情况下，基站向终端发送定位信息是指基站向终端发送包含定位信息的LPP PDU，所以通过第二指示信息，既可以指示终端向所述终端发送LPP PDU失败，也可以指示终端向终端发送定位信息失败。
在一个实施例中，所述定位信息携带在NR定位协议消息中，所述第二指示信息用于指示向所述终端发送定位信息失败。
在定位信息携带在NR定位协议消息中的情况下，基站向终端发送定位信息是指基站向终端发送NR定位协议消息中获取的定位信息，所以通过第二指示信息，可以指示终端向终端发送定位信息失败。
图8是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图8所示，在一些实施例中，所述方法还包括：
在步骤S801中，响应于所述终端不进入非连接态，向所述核心网发送第三指示信息，用于指示需要发送至所述终端的定位信息发送失败。
在一个实施例中，虽然基站可以通过指示终端进入非连接态的信令携带所述定位信息发送至终端，但是所述信令是在终端将要进入非连接态才发送给终端的，若终端不进入非连接态，那么基站就不能向终端发送信令，也就不能通过所述信令携带定位信息发送给终端。
在这种情况下，基站可以向核心网发送第三指示信息，以指示核心网需要发送至所述终端的定位信息发送失败，从而使得核心网确定基站原本是要给终端发送定位信息的，但是出于某些原因发送定位信息失败，进而核心网可以根据需要重新给终端发送定位信息，例如可以指示终端改变发送定位信息的方式，以便能够顺利将定位信息发送至终端。
图9是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图9所示，在一些实施例中，所述向所述核心网发送第三指示信息包括：
在步骤S901中，响应于所述终端切换到其他小区，向所述核心网发送第三指示信息。
在一个实施例中，基站可以在确定终端切换到其他小区时，向核心网发送第三指示信息。其中，终端切换到其他小区，可以是指终端发起了切换到其他小区的流程，但是仍驻留在所述基站。
在确定终端切换到其他小区时，说明终端离开所述基站的小区驻留到其他基站的小区，那么基站就不能通过所述信令携带定位信息发送给终端了，因此可以在这种情况下，基站才完全确定向终端发送定位信息失败，并通过第三指示信息指示核心网需要发送至所述终端的定位信息发送失败。
而在终端不切换到其他小区的情况下，即使终端不进入非连接态，由于终端仍然驻留在所述基站的小区，所以所述基站后续仍有机会向终端发送所述信令，因此可 以不确定为发送定位信息失败，从而不向核心网发送第三指示信息。
需要说明的是，本公开所有实施例中终端不进入非连接态，可以是指终端处于基站对应的服务小区中，并且在该服务小区中不进入非连接态，这个情况可以是基站预测的。例如基站可以根据终端正在进行的业务的情况和/或通信的历史记录，预测终端在后续预设时段内，是否会进入非连接态，若预测终端不会进入非连接态，则确定终端不进入非连接态，否则，确定终端会进入非连接态。
在一个实施例中，所述定位信息携带在LPP PDU中，所述第三指示信息用于指示需要发送至所述终端的LPP PDU发送失败，或者用于指示需要发送至所述终端的定位信息发送失败。
在定位信息携带在LPP PDU中的情况下，基站向终端发送定位信息是指基站向终端发送包含定位信息的LPP PDU，所以通过第三指示信息，既可以指示核心网向需要发送至所述终端的定位信息发送失败，也可以指示核心网需要发送至所述终端的定位信息发送失败。
在一个实施例中，所述定位信息携带在NR定位协议消息中，所述第三指示信息用于指示需要发送至所述终端的定位信息发送失败。
在定位信息携带在NR定位协议消息中的情况下，基站向终端发送定位信息是指基站向终端发送从NR定位协议消息中获取的定位信息，所以通过第三指示信息，可以指示核心网需要发送至所述终端的定位信息发送失败。
在一个实施例中，所述第三指示信息还用于指示发送失败的原因。
基站还可以通过第三指示信息告知核心网发送失败的原因，从而使得核心网确定为什么需要发送至所述终端的定位信息发送失败，进而可以根据需要选择重新向终端发送定位信息。
例如原因为终端切换到其他小区，那么核心网可以确定终端将要切换到的其他小区对应的其他基站，例如可以根据第三指示信息中携带的其他基站的标识确定，进而将定位信息和第一指示信息发送至其他基站，以便终端接入其他基站后，能够从其他基站获取核心网发送的定位信息。
图10是根据本公开的实施例示出的一种定位信息发送方法的示意流程图。本实施例所示的定位信息发送方法可以适用于核心网，所述核心网可以与基站和作为用户设备的终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、 物联网设备等通信装置。所述基站包括但不限于4G基站、5G基站、6G基站。
在一个实施例中，所述基站可以是上述任一实施例所述定位信息发送方法所适用的基站。所述终端可以是后续任一实施例所述的定位信息接收方法所适用的终端。
如图10所示，所述定位信息发送方法可以包括以下步骤：
在步骤S1001中，向基站发送定位信息，所述定位信息供终端进行定位；
在步骤S1002中，向所述基站发送第一指示信息，用于指示所述基站所述定位信息供所述终端在非连接态使用。
需要说明的是，定位信息和第一指示信息可以在同一发送步骤中发送给基站，也可以在不同发送步骤中发送给基站，具体可以根据需要进行设置。
在一个实施例中，核心网可以向基站发送定位信息，其中，定位信息包括但不限于以下至少之一：
定位辅助信息、定位请求信息。
其中，定位辅助信息中携带的内容包括但不限于定位参考信号的配置信息，终端可以根据该配置信息接收定位参考信号；定位请求信息中携带的内容包括但不限于定位请求，用于向终端请求位置信息、对定位参考信号的测量结果等。
在一个实施例中，所述信令包括以下至少之一：
无线资源控制释放信令、无线资源控制挂起信令。
在一个实施例中，所述非连接态包括以下至少之一：
空闲态、非激活态。
基于所述信令的不同，所述非连接态也可以有所不同。例如信令是无线资源控制释放(RRC release)信令，那么第一指示信息指示所述定位信息供所述终端在空闲(idle)态使用；例如信令是无线资源控制挂起(RRC suspend)信令，那么第一指示信息指示所述定位信息供所述终端在非激活(inactive)态使用。
根据本公开的实施例，核心网不仅可以将定位信息发送至基站，还可以向基站发送第一指示信息，使得基站可以根据第一指示信息确定定位信息供终端在非连接态使用，而不是在连接态使用，从而可以通过指示终端进入非连接态的信令携带定位信息发送给终端，而不会使用下行信息传输信令携带定位信息。
据此，使得基站可以明确对于接收到的定位信息，是否使用指示终端进入非连接态的信令携带以发送给终端，避免基站不能确定是通过下行信息传输信令携带定位信息发送给终端，还是通过指示终端进入非连接态的信令携带定位信息发送给终端，避免发送定位信息出现问题。
在一个实施例中，核心网在定位信息供连接态的终端使用的情况下，可以不额外发送指示信息，只发送定位信息给终端，基站即可确定定位信息供连接态的终端使用，进而通过下行信息传输信令携带定位信息发送给终端；或者核心网在定位信息供连接态的终端使用的情况下，也可以额外发送指示信息，指示发送给基站的定位信息供连接态的终端使用，进而基站可以通过下行信息传输信令携带定位信息发送给终端。

例如所述信令为无线资源控制释放信令，那么终端会在进入空闲态后使用所述定位信息进行定位流程；例如所述信令为无线资源控制挂起信令，那么终端会在进入非连接态后使用所述定位信息进行定位流程。
另外，核心网向基站发送的定位信息，可以是新定义的定位信息，以便与已有的供连接态的终端使用的定位信息区分开，例如已有的供连接态的终端使用的定位信息包括LPP provide assistance data和LPP request location information，那么新定义的定位信息可以包括LPP provide assistance data1和LPP request location information1。

图11是根据本公开的实施例示出的另一种定位信息发送方法的示意流程图。如图11所示，在一些实施例中，所述向基站发送定位信息包括：
在步骤S1101中，向所述基站发送LTE定位协议的协议数据单元LPP PDU，所述LPP PDU中携带有所述定位信息；
其中，所述第一指示信息用于指示所述LPP PDU供所述终端在非连接态使用。
在一个实施例中，核心网可以通过LPP PDU携带定位信息发送至基站，在这种情况下，由于LPP PDU是非接入(NAS)层信息，基站并不会解析其中的内容，也即基站一般情况下仅知道接收到核心网发送的LPP PDU，而不知道LPP PDU中携带的是定位信息，所以核心网可以通过第一指示信息指示发送的LPP PDU是供终端在非连接态使用的，那么基站可以将包含所述定位信息的LPP PDU携带在所述信令中发送给终端。
图12是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图12所示，在一些实施例中，所述向基站发送定位信息包括：
在步骤S1201中，向所述基站发送NR定位协议消息，所述NR定位协议消息中携带有所述定位信息；
其中，所述第一指示信息指示所述定位信息供所述终端在非连接态使用。
在一个实施例中，核心网可以通过NR定位协议消息携带定位信息发送至基站，在这种情况下，基站可以解析NR定位协议消息中的内容得到定位信息，那么核心网可以通过第一指示信息指示定位信息是供终端在非连接态使用的，那么基站可以将从NR定位协议消息得到的定位信息携带在所述信令中发送给终端。
图13是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图13所示，在一些实施例中，所述方法还包括：
在步骤S1301中，接收所述基站发送的第三指示信息；
在步骤S1302中，根据所述第三指示信息确定所述基站需要发送至所述终端的定位信息发送失败。
在一个实施例中，虽然基站可以通过指示终端进入非连接态的信令携带所述定位信息发送至终端，但是所述信令是在终端将要进入非连接态才发送给终端的，若终端不进入非连接态，那么基站就不能向终端发送信令，也就不能通过所述信令携带定位信息发送给终端。
在这种情况下，基站可以向核心网发送第三指示信息，以指示核心网需要发送至所述终端的定位信息发送失败，从而使得核心网确定基站原本是要给终端发送定位信息的，但是出于某些原因发送定位信息失败，进而核心网可以根据需要重新给终端 发送定位信息，例如可以指示终端改变发送定位信息的方式，以便能够顺利将定位信息发送至终端。
图14是根据本公开的实施例示出的又一种定位信息发送方法的示意流程图。如图14所示，在一些实施例中，所述方法还包括：
在步骤S1401中，根据所述第三指示信息确定发送失败的原因。
基站还可以通过第三指示信息告知核心网发送失败的原因，从而使得核心网确定为什么需要发送至所述终端的定位信息发送失败，进而可以根据需要选择重新向终端发送定位信息。
例如原因为终端切换到其他小区，那么核心网可以确定终端将要切换到的其他小区对应的其他基站，进而将定位信息和第一指示信息发送至其他基站，以便终端接入其他基站后，能够从其他基站获取核心网发送的定位信息。
图15是根据本公开的实施例示出的一种定位信息接收方法的示意流程图。本实施例所示的定位信息接收方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以作为用户设备与核心网、基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。
在一个实施例中，所述基站可以是上述任一实施例所述定位信息发送方法所适用的基站。所述核心网可以是上述任一实施例所述的定位信息发送方法所适用的核心网。
如图15所示，所述定位信息接收方法可以包括以下步骤：
在步骤S1501中，接收基站指示终端进入非连接态的信令；
在步骤S1502中，从所述信令中获取定位信息。
在一个实施例中，核心网可以向基站发送定位信息，并由基站将定位信息发送至终端，其中，定位信息包括但不限于以下至少之一：
定位辅助信息、定位请求信息。
其中，定位辅助信息中携带的内容包括但不限于定位参考信号的配置信息，终端可以根据该配置信息接收定位参考信号；定位请求信息中携带的内容包括但不限于定位请求，用于向终端请求位置信息、对定位参考信号的测量结果等。
在一个实施例中，所述信令包括以下至少之一：
无线资源控制释放信令、无线资源控制挂起信令。
在一个实施例中，所述非连接态包括以下至少之一：
空闲态、非激活态。
基于所述信令的不同，所述非连接态也可以有所不同。例如信令是无线资源控制释放(RRC release)信令，那么第一指示信息指示所述定位信息供所述终端在空闲(idle)态使用；例如信令是无线资源控制挂起(RRC suspend)信令，那么第一指示信息指示所述定位信息供所述终端在非激活(inactive)态使用。
根据本公开的实施例，终端可以在接收到所述信令之后进入非连接态，并在非连接态下根据从所述信令中获取的定位信息进行定位，实现了终端在非连接态下的定位。终端在完成定位后，可以将定位结果经由基站发送给核心网，核心网即可得到终端在非连接态下的定位结果。
另外，核心网不仅可以将定位信息发送至基站，还可以向基站发送第一指示信息，使得基站可以根据第一指示信息确定定位信息供终端在非连接态使用，而不是在连接态使用，从而可以通过指示终端进入非连接态的信令携带定位信息发送给终端，而不会使用下行信息传输信令携带定位信息。
据此，使得基站可以明确对于接收到的定位信息，是否使用指示终端进入非连接态的信令携带以发送给终端，避免基站不能确定是通过下行信息传输信令携带定位信息发送给终端，还是通过指示终端进入非连接态的信令携带定位信息发送给终端，避免发送定位信息出现问题。
在一个实施例中，核心网在定位信息供连接态的终端使用的情况下，可以不额外发送指示信息，只发送定位信息给终端，基站即可确定定位信息供连接态的终端使用，进而通过下行信息传输信令携带定位信息发送给终端；或者核心网在定位信息供连接态的终端使用的情况下，也可以额外发送指示信息，指示发送给基站的定位信息供连接态的终端使用，进而基站可以通过下行信息传输信令携带定位信息发送给终端。
需要说明的是，终端可以与网络侧约定，或者由协议规定，终端在进入非连接态后，才会使用携带在所述信令中的定位信息进行定位流程，而在连接态下，终端即使接收到了所述信令，也不会使用携带在所述信令中的定位信息进行定位流程。
例如所述信令为无线资源控制释放信令，那么终端会在进入空闲态后使用所述定位信息进行定位流程；例如所述信令为无线资源控制挂起信令，那么终端会在进入 非连接态后使用所述定位信息进行定位流程。
另外，核心网向基站发送的定位信息，可以是新定义的定位信息，以便与已有的供连接态的终端使用的定位信息区分开，例如已有的供连接态的终端使用的定位信息包括LPP provide assistance data和LPP request location information，那么新定义的定位信息可以包括LPP provide assistance data1和LPP request location information1。
图16是根据本公开的实施例示出的另一种定位信息接收方法的示意流程图。如图16所示，在一些实施例中，所述信令携带的LPP PDU中携带有所述定位信息，所述从所述信令中获取定位信息包括：
在步骤S1601中，从所述LPP PDU中获取所述定位信息。
在一个实施例中，核心网可以通过LPP PDU携带定位信息发送至基站，在这种情况下，由于LPP PDU是非接入(NAS)层信息，基站并不会解析其中的内容，也即基站一般情况下仅知道接收到核心网发送的LPP PDU，而不知道LPP PDU中携带的是定位信息，所以核心网可以通过第一指示信息指示发送的LPP PDU是供终端在非连接态使用的，那么基站可以将包含所述定位信息的LPP PDU携带在所述信令中发送给终端。
在一个实施例中，由于LPP PDU是非接入层信息，基站接收到LPP PDU后，可以将LPP PDU透传至终端，也即一般情况下基站不对LPP PDU进行解析去获取其中的定位信息，而是直接将接收到的LPP PDU携带在所述信令中发给终端，那么终端可以从接收到的LPP PDU中获取所述定位信息。
在一些实施例中，所述信令携带有所述定位信息。
在一个实施例中，核心网可以通过NR定位协议消息携带定位信息发送至基站，在这种情况下，基站可以解析NR定位协议消息中的内容得到定位信息，那么核心网可以通过第一指示信息指示定位信息是供终端在非连接态使用的，那么基站可以将从NR定位协议消息得到的定位信息携带在所述信令中发送给终端。
在一个实施例中，基站接收到NR定位协议消息后，可以解析NR定位协议消息以获取其中的定位信息，进而将从NR定位协议消息得到的定位信息携带在所述信令中发给终端，那么终端可以从信令中直接获取定位信息。
需要说明的是，核心网发送给基站的携带定位信息的NR定位协议消息，可以是指定终端专属的，例如可以在NR定位协议消息中携带指定终端的标识，以使基站 可以根据标识确定将定位信息发送至指定终端。
图17是根据本公开的实施例示出的另一种定位信息接收方法的示意流程图。如图17所示，在一些实施例中，所述方法还包括：
在步骤S1701中，响应于不进入非连接态，接收所述基站发送的第二指示信息；
在步骤S1702中，根据所述第二指示信息确定所述基站向所述终端发送定位信息失败。
在一个实施例中，虽然基站可以通过指示终端进入非连接态的信令携带所述定位信息发送至终端，但是所述信令是在终端将要进入非连接态才发送给终端的，若终端不进入非连接态，那么基站就不能向终端发送信令，也就不能通过所述信令携带定位信息发送给终端。
在这种情况下，基站可以向终端发送第二指示信息，以指示终端向终端发送定位信息失败，从而使得终端确定基站原本是要给终端发送定位信息的，但是出于某些原因发送定位信息失败，进而终端在需要获取定位信息时，可以通过与基站、核心网等网络侧设备通信，重新获取定位信息。
图18是根据本公开的实施例示出的另一种定位信息接收方法的示意流程图。如图18所示，在一些实施例中，所述接收所述基站发送的第二指示信息包括：
在步骤S1801中，响应于切换到其他小区，接收所述基站发送的第二指示信息。
在一个实施例中，基站可以在确定终端切换到其他小区时，向终端发送第二指示信息，那么相应地，终端在确定需要切换到其他小区时，才能接收到基站发送的第二指示信息，其中，终端切换到其他小区，可以是指终端发起了切换到其他小区的流程，但是仍驻留在所述基站。
在确定终端切换到其他小区时，说明终端离开所述基站的小区驻留到其他基站的小区，那么基站就不能通过所述信令携带定位信息发送给终端了，因此可以在这种情况下，基站才完全确定向终端发送定位信息失败，并通过第二指示信息指示终端向终端发送定位信息失败。
而在终端不切换到其他小区的情况下，即使终端不进入非连接态，由于终端仍然驻留在所述基站的小区，所以所述基站后续仍有机会向终端发送所述信令，因此可以不确定为发送定位信息失败，从而不向终端发送第二指示信息。
