具体实施方式
为了便于理解，首先介绍本公开涉及的术语。
1、按需(on-demand)PRS
为了更好的满足定位的需求，例如提高定位精度，提高网络效率，也考虑在通信系统中引入on-demand PRS,即按需请求PRS。对于on-demand PRS，可以包括以下几种方式：
终端设备向LMF发送on-demand PRS请求；
LMF向gNB发送on-demand PRS请求；以及
终端设备向gNB发送on-demand PRS请求。
2、新空口定位协议A(new radio positioning protocol A，NRPPa)消息
NRPPa为用于规范基站和LMF之间的控制平面无线网络层信令过程的协议。LMF与gNB之间的NRPPa消息可以分为：非终端设备相关(non UE associated)消息及终端设备相关(UE associated)消息。
其中，Non UE associated消息可以用来在基站和LMF之间传输TRP信息、测量信息及辅助信息等的传输。UE associated消息可以用来在基站和LMF之间传输指定的终端设备相关的信息，比如终端设备的TRP配置信息等。目前LMF向基站发送PRS配置信息请求使用的是Non UE associated消息。
为了更好的理解本公开实施例公开的一种定位参考信号配置信息的确定方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个基站、一个LMF设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的基站，两个或两个以上的终端设备，两个或两个以上的LMF设备。图1所示的通信系统以包括一个LMF设备11、一个终端设备12和一个基站13为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。本公开实施例中的基站13是网络侧的一种用于发射或接收信号的实体。例如，基站13可以为演进型基站(evolved NodeB，eNB)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
本公开实施例提供的LMF设备11及基站13可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)。采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的PRS配置信息的确定方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种PRS配置信息的确定方法的流程示意图。该方法被配置为由LMF设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21：基于非终端设备相关消息或终端设备相关消息，向基站发送PRS配置信息请求。
本公开中，为了提高定位的精度及效率，LMF设备可以利用多种消息，向基站请求PRS配置信息。
可选的，LMF设备可以基于非终端设备相关消息，比如TRP信息请求(information request)消息，向基站请求提供PRS配置信息。可以理解的是，基于TRP information request消息向基站请求PRS配置信息时，基站可以为LMF设备或者为终端设备提供小区级的PRS配置信息。
可选的，LMF设备还可以基于指定的位置信息请求(Positioning information request)消息，向基站请求提供PRS配置信息。
其中，指定的Positioning information request消息，可以为LMF设备通过扩展Positioning information request消息的长度，比如在Positioning information request消息中增加是否请求PRS配置信息的比特位，通过为该比特位配置不同值，以向基站指示该消息是否同时请求PRS配置信息。
可选的，LMF设备还可以基于指定的终端设备相关消息，向基站请求提供PRS配置信息。
其中，指定的终端终端设备相关消息，可以为LMF设备根据协议约定或者网络配置生成的。可以理 解的是，任何可以向基站指示该消息类型为终端设备相关的、且是用于请求终端设备级的PRS配置信息的消息的格式及类型，都可以作为本公开中的指定的终端设备相关消息。
可以理解的是，本公开中，LMF设备基于非终端设备相关消息或终端设备相关消息，向基站发送PRS配置信息请求，从而即可获得多种类型的PRS配置信息。比如可以获取终端设备级的PRS配置信息，也可以获得基站级、或者TRP级的PRS配置信息，从而不仅丰富了PRS配置信息获取方式的多样性，而且为终端设备的定位提供了更可靠、更准确的PRS配置信息，从而提高了定位结果的精度和可靠性。
需要说明的是，本公开中终端设备级的PRS配置信息，是指供指定的终端设备定位使用的PRS配置信息。而基站级、TRP级或者小区级的PRS配置信息，是指所有需要该基站、TRP或者小区的PRS的终端设备进行定位时使用的PRS配置信息。
相应的，终端设备级的PRS配置信息，可以通过终端设备相关消息进行传输，而基站级、TRP级或者小区级的PRS配置信息可以通过非终端设备相关消息进行传输。
可选的，本公开中LMF设备，可以根据需要确定向基站发送PRS配置信息请求的时机。
比如，LMF设备为了更好的满足定位需求，比如提高定位精度，需求对PRS配置信息进行更新，从而可以基于非终端设备相关消息或终端设备相关消息，向基站发送按需(on-demand)PRS配置信息请求。
或者，终端设备为了更好的满足定位需求，可能会向LMF发送on-demand PRS配置信息请求，之后LMF设备则可以在接收到终端设备发送的按需PRS配置信息请求后，基于终端设备相关消息，向基站发送PRS配置信息更新请求。
或者，为了实现定位功能，LMF在初次获取基站的PRS配置信息时，可以基于非终端设备相关消息，向基站发送初始PRS配置信息请求，以获取初始PRS配置信息，从而进行定位。
可选的，LMF设备为了更好的满足定位需求，比如更灵活、更准确的定位，也可以基于不同的消息，向基站请求不同类型的PRS配置信息。
比如，由于非周期PRS或者半持续的PRS，在时间上持续的时间较短，更有利于满足终端设备的定位需求，从而LMF在请求的PRS配置信息为非周期PRS或半持续PRS的情况下，可以基于终端设备相关消息，向基站发送PRS配置信息请求。
或者，在请求的PRS配置信息为周期PRS的情况下，可以基于非终端设备相关消息，向基站发送PRS配置信息请求。从而可以对小区级的PRS配置信息进行周期性的更新，以保证各个终端设备定位的精度和可靠性。
通过实施本公开实施例，LMF设备可以基于非终端设备相关消息或终端设备相关消息，向基站发送PRS配置信息请求，以获取多种类型的PRS配置信息,从而不仅丰富了请求PRS配置信息的形式，而且为终端设备的定位提供了更可靠、更准确的PRS配置信息，从而提高了定位结果的精度和可靠性。
请参见图3，图3是本公开实施例提供的另一种定位参考信号配置信息的确定方法的流程示意图。该方法被配置为由LMF设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，响应于接收的终端设备发送的按需PRS配置信息请求的数量小于或等于阈值，基于终端设备相关消息，向基站发送PRS配置信息请求。
本公开中，终端设备为了更好的满足定位需求，可能会向LMF发送on-demand PRS配置信息请求，而LMF设备在接收到终端设备发送的按需PRS配置信息请求时，就可以基于终端设备相关消息，向基站发送PRS配置信息请求，以请求该终端设备的PRS配置信息。
本公开中LMF设备若收到的终端设备发送的按需PRS配置信息请求的数量为N，且小于阈值，则LMF设备向基站发送PRS配置信息请求时，可以向基站发送N次PRS配置信息请求，以为N个终端设备分别请求其对应的PRS配置信息。或者，也可以利用一条终端设备相关消息，请求N个终端设备分别对应的PRS配置信息。比如，可以将Positioning information request消息进行扩展，以使其可以一次请求多个PRS配置信息，或者，也可以定义新的终端设备相关消息，以一次性请求多个PRS配置信息，本公开对此不做限定。
由于，LMF设备在同一时刻接收的终端设备发送的按需PRS配置信息请求的数量可能不同，此时若都基于终端设备相关消息，则基站可能没有足够的资源来为每个请求PRS配置信息的终端设备都配置一个特定的PRS配置信息，因此，本公开中，可以根据协议约定或者网络配置一个阈值，从而使LMF仅在接收到的按需PRS配置信息请求的数量小于或等于该阈值时，才通过终端设备相关消息，向基站发送PRS配置信息请求。
其中，本公开对该阈值的大小不做限定。
可选的，若LMF接收的终端设备发送的按需PRS配置信息请求的数量大于阈值，则LMF即可基于非 终端设备相关消息，向所述基站发送PRS配置信息请求。即，当LMF同时收到多个终端设备发送的PRS配置信息请求时，则说明多个终端设备都有更准确的定位需求，从而即可直接向基站发送非终端设备相关消息，以请求PRS配置信息，从而即可获取到基站级或者TRP级的PRS配置信息，以供所述多个终端设备使用，以使有定位需求的终端设备都可以实现准确定位。由于不仅降低了LMF在请求PRS配置信息时的资源量，又提高了获取PRS配置信息的效率。另外，当LMF接收的终端设备发送的按需PRS配置信息请求的数量大于阈值时，基站也可能没有足够的资源来为每个请求PRS配置信息的终端设备都配置一个特定的PRS配置信息，因此LMF可基于非终端设备相关消息，向所述基站发送PRS配置信息请求，从而获取到基站级或者TRP级的PRS配置信息以供所述多个终端设备使用。
可选的，由于不同的终端设备所处的小区不同，为了进一步提高LMF请求的PRS配置信息更有针对性，更准确，本公开在LMF在接收的发送的按需PRS配置信息请求的数量大于阈值的情况下，还可以先确定接收到的多个按需PRS配置信息对应的公共PRS配置信息，进而再基于非终端设备相关消息，向基站发送公共PRS配置信息请求。
其中，LMF可以根据多个终端设备的PRS配置信息请求中的辅助信息，比如终端设备的位置、或者其他信息，确定多个按需PRS配置信息对应的公共PRS配置信息，本公开对此不做限定。
步骤32，接收基站基于终端设备相关消息返回的PRS配置信息。
可选的，基站基于终端设备相关消息返回的PRS配置信息中，可以包括终端设备的标识或者其他任一可辅助LMF确定该PRS配置信息对应的终端设备的标识，比如可以为PRS配置信息标识等等，本公开对此不做限定。
步骤33，将PRS配置信息发送给第二指定的终端设备，其中，所述第二指定的终端设备为向所述LMF设备发送了按需PRS配置信息请求的终端设备。
其中，第二指定的终端设备，可能为一个终端设备，也可能为多个终端设备，本公开对此不做限定。
可选的，LMF可以基于长期演进LTE定位协议LPP消息，将PRS配置信息发送给第二指定的终端设备。
可选的，基站在接收到LMF基于终端设备相关消息发送的PRS配置信息请求后，若无法确定第二指定的终端设备的PRS配置信息，或者，确定的该第二指定的终端设备的PRS配置信息与基站或TRP的PRS配置信息相同，也可能会基于非终端相关消息向LMF返回PRS配置信息。从而LMF即可将接收的PRS配置信息发送给第二指定的终端设备及其他终端设备，本公开对此不做限定。
通过实施本公开实施例，LMF在接收的终端设备发送的按需PRS配置信息请求的数量小于或等于阈值，基于终端设备相关消息，向基站发送PRS配置信息请求，并且在接收到基站基于终端设备相关消息返回的PRS配置信息后，将该信息发送给第二指定的终端设备。由此，在不增加过多网络资源的情况下，不仅丰富了请求PRS配置信息的形式，而且为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性。
请参见图4，图4是本公开实施例提供的另一种定位参考信号配置信息的确定方法的流程示意图。该方法被配置为由LMF设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，基于非终端设备相关消息或终端设备相关消息，向基站发送PRS配置信息请求。
本公开实施例中，LMF设备确定向基站发送PRS配置信息请求的方式及参考依据，可以参照本公开任一实施例的详细描述，此处不再赘述。
步骤42，响应于基于非终端设备相关消息接收到基站返回的PRS配置信息，向基站发送第一指示信息，其中，第一指示信息用于指示基站将PRS配置信息通过系统信息块SIB发送给终端设备。
通常，LMF在向基站发送了PRS配置信息请求后，基站可以将PRS配置信息返回给LMF设备，之后LMF设备将PRS配置信息再发送给终端设备。
本公开中，若LMF设备向基站请求的PRS配置信息为基站或者TRP的配置信息，即是多个终端设备在定位过程中都可以使用的小区级的PRS配置信息，从而为了使得各终端设备尽快获得PRS配置信息，本公开中，也可以由LMF设备指示基站，直接将该PRS配置信息发送给终端设备。
可选的，LMF设备可以指示基站基于定位positioning SIB向终端设备发送PRS配置信息等，本公开对此不做限定。
可选的，若LMF设备在向基站发送的PRS配置信息请求后，接收到基站基于非终端设备相关消息返回的PRS配置信息，则可以基于LPP消息，将PRS配置信息发送给第一指定的终端设备。其中，该第一指定的终端设备为向其发送了on-demand PRS配置信息请求的终端设备、和/或已经配置了该基站的PRS配置信息的终端设备。
其中，第一指定的终端设备可能为一个，也可能为多个，本公开对此不做限定。
可以理解的是，本公开中，无论LMF设备基于何种消息向基站发送的PRS配置信息请求，只要其接 收到基站返回的PRS配置信息是基于非终端设备相关消息的，则可以将接收到的PRS配置信息发送给有定位需求的终端设备，和/或之前已经配置该基站的PRS配置信息的终端设备。而只要其接收到基站返回的PRS配置信息是基于终端设备相关消息的，则仅可以将接收到的PRS配置信息发送给该终端设备相关消息对应的指定的一个或几个终端设备。
通过实施本公开实施例，LMF设备首先基于非终端设备相关消息或终端设备相关消息，向基站发送PRS配置信息请求，之后若基于非终端设备相关消息接收到所述基站返回的PRS配置信息，则还可以向基站发送用于指示基站将PRS配置信息通过系统信息块SIB发送给终端设备的第一指示信息。由此，不仅丰富了请求PRS配置信息的形式，而且提高了终端设备获取PRS配置信息的效率，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性。

本公开中，为了减少PRS配置信息占用的设备资源，终端设备在定位完成后，可以向LMF设备发送第二指示信息，以指示释放其对应的PRS配置信息。从而，LMF设备即可向基站发送第三指示信息，以指示基站释放第一指定的终端设备对应的PRS配置信息。
可选的，本公开中LMF设备，也可以直接向基站发送第三指示信息，以指示基站释放该第二指定的终端设备对应的PRS配置信息，即LMF是否发送第三指示信息不基于是否接收到终端设备发送的第二指示信息。比如，LMF设备可以在确定终端设备定位结束后，向基站发送第三指示信息，以指示基站释放该第二指定的终端设备对应的PRS配置信息。
可选的，用于指示基站释放第二指定的终端设备对应的PRS配置信息的指示信息，也可以是由第二指定的终端设备向其发送的，本公开对此不做限定。
通过实施本公开实施例，LMF设备在基于终端设备相关消息或非终端设备相关消息向基站请求PRS配置信息后，若基于终端设备相关消息接收到PRS配置信息，则将该配置信息发送给第二指定的终端设备，并可以在接收到第二指定的终端设备发送的第二指示信息后，指示基站释放该第二指定的终端设备对应的PRS配置信息。由此，不仅丰富了请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性，而且避免了PRS配置信息过久的占用设备资源。

可选的，本公开中LMF设备，也可以直接向基站发送第三指示信息，以指示基站释放该第二指定的终端设备对应的PRS配置信息，即LMF是否发送第三指示信息不基于是否接收到终端设备发送的第二指示信息。比如，LMF设备可以在确定终端设备定位结束后，向基站发送第三指示信息，以指示基站释放该第二指定的终端设备对应的PRS配置信息。
可选的，用于指示基站释放第二指定的终端设备对应的PRS配置信息的指示信息，也可以是由第二指定的终端设备向其发送的，本公开对此不做限定。
通过实施本公开实施例，LMF设备在接收到终端设备发送的按需PRS配置信息请求时，即可基于终端设备相关消息向基站请求PRS配置信息，在基于终端设备相关消息接收到PRS配置信息后，将该配置信息发送给第二指定的终端设备，并可以在接收到第二指定的终端设备发送的第二指示信息后，指示基站释放该第二指定的终端设备对应的PRS配置信息。由此，不仅丰富了请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性，而且避免了PRS配置信息过久的占用设备资源。

步骤62，接收网络设备返回的PRS配置信息。
本公开中，为了更好的满足终端设备的定位需求，终端设备可以根据需要，向LMF设备或基站请求PRS配置信息。以从LMF设备或基站处获取最新的PRS配置信息，进而基于获取的PRS配置信息进行定位。
可选的，若网络设备为LMF设备，则终端设备可以基于LPP消息接收PRS配置信息。
可以理解的是，若网络设备为LMF设备，则LMF设备还需要向基站发送PRS配置信息请求，以从基站侧请求PRS配置信息，然后再将基站返回的PRS配置信息发送给终端设备。
可选的，若网络设备为基站，则终端设备可以基于SIB接收基站返回的PRS配置信息。比如，可以基于定位positioning SIB接收接收基站返回的PRS配置信息。
其中，终端设备向网络设备发送的按需PRS配置信息请求、及接收网络设备返回的PRS配置信息的具体实现形式，可参照本公开任一实施例的详细描述，此处不再赘述。
通过实施本公开实施例，终端设备可以向LMF设备或基站发送按需PRS配置信息请求，以获取LMF设备或基站返回的PRS配置信息。由此，丰富了终端设备请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性。

步骤72，接收LMF设备基于LPP消息返回的PRS配置信息。
步骤72，响应于定位过程结束，向LMF设备发送第二指示信息，其中，第二指示信息用于指示LMF设备释放终端设备对应的PRS配置信息。
可选的，若终端设备向基站发送的按需PRS配置信息请求，则在定位过程接收后，也可以向基站发送第四指示信息，其中，第四指示信息用于指示基站释放终端设备对应的PRS配置信息。
本公开中，为了减少PRS配置信息占用的设备资源，终端设备在定位完成后，可以向LMF设备发送第二指示信息，以指示LMF设备释放其对应的PRS配置信息。相应的，终端设备也可以向基站发送第四指示信息，以指示基站释放其对应的PRS配置信息。
需要说明的是，若终端设备是向LMF设备请求的PRS配置信息，那么在其向LMF设备发送了第二指示信息后，LMF设备向基站发送第三指示信息，以指示基站释放该终端设备对应的PRS配置信息。
通过实施本公开实施例，终端设备首先向LMF设备发送按需PRS配置信息请求，之后在接收到LMF设备返回的PRS配置信息时，即可基于该PRS配置信息进行定位，并在定位结束后，向LMF设备发送第二指示信息，以指示LMF设备释放其对应的PRS配置信息。由此，不仅丰富了请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性，而且避免了PRS配置信息过久的占用设备资源。

步骤81，接收通信设备发送的PRS配置信息请求，其中，通信设备为LMF或者终端设备，LMF设备发送的PRS配置信息请求为非终端设备相关消息或终端设备相关消息。

其中，非终端设备相关消息及终端设备相关消息的具体使用场景，可以参照本公开其他各实施例的详细说明，此处不再赘述。
需要说明的是，若基站接收的PRS配置信息请求，为终端设备发送的，则说明该PRS配置信息请求为终端设备相关消息。
可选的，若基站收到的PRS配置请求为终端设备相关消息，则可以确定待发送的PRS配置信息为指定的终端设备在定位过程中要使用的信息，即该PRS配置信息为终端设备级的。从而基站即可为该指定的终端设备确定其对应的PRS配置信息，并基于终端设备相关消息，将确定的PRS配置信息，发送给LMF设备或者终端设备。
或者，若基站收到的PRS配置请求为非终端设备相关消息，则可以确定待发送的PRS配置信息为某个基站或者TRP下的所有终端设备在定位过程中要使用的信息，即该PRS配置信息为小区cell级的。从而基站即确定小区级的PRS配置信息，并基于非终端设备相关消息，将确定的PRS配置信息，发送给LMF设备或者终端设备。
可选的，基站可以通过SIB消息，将小区级的PRS配置信息，发送给终端设备，或者，可以通过TRP信息响应(information response)将小区级的PRS配置信息发送给LMF设备，再有LMF设备将小区级的PRS配置信息发送给各个终端设备，本公开对此不做限定。

通过实施本公开实施例，基站在收到通信设备发送的PRS配置信息请求后，即可向请求的通信设备返回PRS配置信息。由此，丰富了请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性。
请参见图9，图9是本公开实施例提供的另一种PRS配置信息的确定方法的流程示意图。该方法被配置为由基站执行。如图9所示，该方法可以包括但不限于如下步骤：

步骤92，基于终端设备相关消息，向LMF设备返回终端设备级的PRS配置信息。
步骤93，响应于接收到所述LMF设备发送的第三指示信息，释放PRS配置信息，其中，第三指示信息用于指示基站释放PRS配置信息。
可以理解的是，LMF设备在接收到基站基于终端设备相关消息返回的PRS配置信息后，即可将该信息通过LPP消息，发送给指定的终端设备。之后，在收到该指定的终端设备发送的释放PRS配置信息的第二指示信息后，即可向基站发送第三指示信息，以指示基站释放PRS配置信息。从而即实现了终端设备的可靠定位，又避免了PRS配置信息长久的占用网络设备资源。
可选的，本公开中LMF设备，也可以在将PRS配置信息发送给指定的终端设备后，自动触发向基站发送第三指示信息，以指示基站释放该指定的终端设备对应的PRS配置信息。比如，LMF设备可以基于协议约定的时间间隔，在向指定的终端设备发送PRS配置信息后，到达了指定的时间间隔时，即触发向基站发送第三指示信息，以指示基站释放该指定的终端设备对应的PRS配置信息。
可选的，基站也可能在接收到该终端设备发送的第四指示信息时，释放该终端设备对应的PRS配置信息，其中，第四指示信息用于指示基站释放其对应的PRS配置。
需要说明的是，基站在接收到LMF设备基于终端设备相关消息发送的PRS配置信息请求，或者接收到终端发送的PRS配置信息请求后，可能并不能确定出指定的终端设备对应的PRS配置信息，或者，确定的PRS配置信息不是终端设备级的，那么基站也可以基于非终端设备相关消息向LMF设备或者终端设备返回PRS配置信息，以使多个终端设备都可以基于该PRS配置信息进行定位。
通过实施本公开实施例，基站在接收到LMF设备基于终端设备相关消息发送的PRS配置信息请求后，即可确定指定的终端设备对应的PRS配置信息，并基于终端设备相关消息向LMF设备返回PRS配置信息，并在接收到LMF设备发送的第三指示信息后，即释放该PRS配置信息。由此，不仅丰富了请求PRS配置信息的形式，为终端设备的定位提供了更可靠、更准确的PRS配置信息，提高了定位结果的精度和可靠性，而且避免了PRS配置信息过久的占用设备资源。
请参见图10，图10是本公开实施例提供的一种PRS配置信息确定方法的交互信令示意图。如图10所示，该方法可以包括但不限于如下步骤：

步骤102，LMF设备基于非终端设备相关消息，向基站发送更新PRS配置信息请求。

例如，基站可以通过TRP information response消息向LMF设备发送更新后的PRS配置信息。
步骤104，LMF设备将该配置通过LPP消息发送给终端设备1。
步骤105，LMF设备将更新后的PRS配置信息通过LPP消息发送给终端设备2。
其中，终端设备2为正在定位过程中、且使用了基站的PRS配置信息的任一终端设备。
步骤106，LMF设备触发基站更新positioning sib，以包含更新后的PRS配置信息。
需要说明的是，本实施例中LMF向基站发送更新PRS配置信息请求也可以是LMF设备自动触发的，而非收到终端设备发送的on-demand PRS请求后才触发的。比如，可以是LMF设备为了更新PRS配置信息，或者为了某个终端设备向基站发送了non UE associated NRPPa消息，以请求更新PRS配置信息等，本公开对此不做限定。
另外，本实施例中，LMF设备在基于非终端关联消息收到基站返回的PRS配置信息后，通过触发基站发送更新positioning SIB，以使更新后的positioning SIB包含更新后的PRS配置信息，以使各个终端设备都可以接收到该更新后的PRS配置信息，从而提高各个终端设备定位的准确性和可靠性。
请参见图11，图11是本公开实施例提供的另一种PRS配置信息确定方法的交互信令示意图。如图11所示，该方法可以包括但不限于如下步骤：
步骤111，终端设备1向LMF设备发送on-demand PRS请求。
步骤112，LMF设备向基站发送UE associated NRPPa消息，以请求更新PRS配置信息。
比如，LMF设备可以通过Positioning information request发送该请求。
步骤113，基站向LMF设备提供更新后的PRS配置信息。
例如，基站可以通过Positioning information response消息向LMF设备发送更新后的PRS配置信息。
步骤114，LMF设备收到更新后的PRS配置信息，并将该配置信息通过LPP消息发送给终端设备1。
需要说明的是，此时若终端设备2正在定位过程中，且使用了该基站的配置信息，则LMF设备不需要将更新后的PRS配置通过LPP消息发送给该终端设备2。
步骤115，当终端设备1定位结束后，终端设备1向LMF设备发送指示信息，以指示LMF设备释放其对应的PRS配置信息。
步骤116，LMF设备向基站发送UE associated的NRPPa消息，以指示基站释放其为终端设备1配置的PRS配置信息。
