S201：UE向定位服务器发送第一指示信息。S201: The UE sends the first indication information to the positioning server.
第一指示信息中包含UE的定位参数，定位服务器通过第一指示信息获取UE的定位参数。The first indication information includes a positioning parameter of the UE, and the positioning server acquires a positioning parameter of the UE by using the first indication information.
其中，UE的定位参数包括但不限于如下参数：The positioning parameters of the UE include but are not limited to the following parameters:

其中，UE的定位时间，包括：UE开始定位的时间、UE的定位持续时间和/或UE的定位周期。The positioning time of the UE includes: a time when the UE starts positioning, a positioning duration of the UE, and/or a positioning period of the UE.
所述UE的定位方式包括：基于UE的定位方式或UE辅助的定位方式。The positioning manner of the UE includes: a positioning manner based on the UE or a positioning manner assisted by the UE.
所述UE的定位状态包括：所述UE处于定位状态或者所述UE未处于定位状态。The positioning status of the UE includes: the UE is in a positioning state or the UE is not in a positioning state.
UE向定位服务器发送第一指示信息包括但不限于如下可能的实现方式：The sending, by the UE, the first indication information to the positioning server includes, but is not limited to, the following possible implementation manners:
其中，一种可能的实现方式：Among them, a possible implementation:
UE在密钥管理流程中向定位服务器发送第一指示信息。The UE sends the first indication information to the positioning server in the key management process.
具体地，UE将第一指示信息携带在发送给MME的附着(Attach)消息或者跟踪区域更新(Tracking Area Update,TAU)消息中。然后MME将该指示信息发送给定位服务器。第一指示信息用于指示UE的定位参数，具体地，可以直接在第一指示信息中携带UE的定位参数，也可以在第一指示信息中携带UE的定位参数的索引等，对此，本申请不作限制。Specifically, the UE carries the first indication information in an Attach message or a Tracking Area Update (TAU) message sent to the MME. The MME then sends the indication information to the location server. The first indication information is used to indicate the positioning parameter of the UE. Specifically, the positioning parameter of the UE may be directly carried in the first indication information, and the index of the positioning parameter of the UE may be carried in the first indication information, etc. There are no restrictions on the application.
类似的，UE发送给定位服务器的定位参数，可以通过UE到核心网设备的非接入层(non-access stratum，NAS)消息，然后核心网设备再将定位参数通过LCS应用协议(LCS Application Protocol，LCS-AP)消息发送给定位服务器。具体信令名称不限制。Similarly, the positioning parameter sent by the UE to the positioning server may be through a non-access stratum (NAS) message of the UE to the core network device, and then the core network device passes the positioning parameter through the LCS Application Protocol (LCS Application Protocol). , LCS-AP) message is sent to the location server. The specific signaling name is not limited.
另一种可能的实现方式：Another possible implementation:
UE将第一指示消息携带在发送给定位服务器的任一LTE定位协议(LTE Positioning Protocol，LPP)消息中。该消息可以为密钥请求消息，具体消息名称不限制。即该指示消息可以在密钥信息请求或传输消息。The UE carries the first indication message in any LTE Positioning Protocol (LPP) message sent to the positioning server. The message can be a key request message, and the specific message name is not limited. That is, the indication message can request or transmit a message in the key information.
S202：定位服务器根据UE的定位参数，确定需要辅助数据的UE的个数。S202: The positioning server determines, according to the positioning parameter of the UE, the number of UEs that need auxiliary data.
UE的定位方式包括：基于UE的定位方式和UE辅助的定位方式，触发定位请求的实体，包括UE，核心网(如MME)，移动定位业务(Location Services，LCS)实体。对于使用UE辅助的定位方式，以及网络触发的定位请求，定位服务器获知UE是否处于定位状态，进而可以确定需要辅助数据的UE的数量。The positioning mode of the UE includes: an entity that triggers a positioning request, including a UE, a core network (such as an MME), and a location location service (LCS) entity, based on the UE's positioning mode and the UE-assisted positioning mode. For the UE-assisted positioning method and the network-triggered positioning request, the positioning server knows whether the UE is in the positioning state, and thus can determine the number of UEs that need assistance data.
但是上述方式，定位服务器不能准确的确定需要辅助数据UE的数量，比如UE触发的定位，且是基于UE的定位方式，即UE自己可以计算出定位结果，若UE可以从***消息中获得辅助数据，则定位服务器不能获得准确的需要辅助数据的UE的数目。However, in the above manner, the positioning server cannot accurately determine the number of the UEs that need the assistance data, such as the location triggered by the UE, and is based on the positioning mode of the UE, that is, the UE can calculate the positioning result by itself, and if the UE can obtain the auxiliary data from the system message. Then, the positioning server cannot obtain the exact number of UEs that need assistance data.
因此，定位服务器还可以进一步地结合UE的定位参数，如UE的定位时间、UE的定位状态、UE是否将要定位、是否接收辅助数据和/或是否感兴趣接收所述辅助数据、UE的定位方法和/或辅助数据的类型等，确定不同的时间段需要辅助数据的UE的数量。Therefore, the positioning server may further combine the positioning parameters of the UE, such as the positioning time of the UE, the positioning status of the UE, whether the UE is to be located, whether to receive auxiliary data, and/or whether it is interested in receiving the auxiliary data, and the positioning method of the UE. And/or the type of auxiliary data, etc., determine the number of UEs that need assistance data for different time periods.
示例的，定位服务器可以根据收到的UE定位参数(如是否正在接收某种定位方法或者某种辅助数据类型的数据或者是否感兴趣接收某种定位方法或者某种辅助数据类型的数据)来判断对于某一定位方法或者某种辅助数据类型的辅助数据需要的UE数目，若对某一定位方法或者某种辅助数据类型需要或感兴趣的UE较多，则定位服务器开启或者维持对该定位方法或者某种辅助数据类型的辅助数据的广播，如果对某一定位方法或者某种辅助数据类型需要或感兴趣感兴趣的用户较少，则定位服务器可 以决策停止对该定位方法或者某种辅助数据类型的辅助数据的广播。或者不对这种定位方法的辅助数据开启广播。For example, the positioning server may determine according to the received UE positioning parameters (such as whether to receive a certain positioning method or some auxiliary data type data or whether it is interested in receiving a certain positioning method or data of a certain auxiliary data type). The number of UEs required for a certain positioning method or auxiliary data of a certain auxiliary data type, if there are more UEs that need or are interested in a certain positioning method or a certain auxiliary data type, the positioning server starts or maintains the positioning method. Or broadcast of auxiliary data of a certain auxiliary data type. If there are fewer users interested in or interested in a certain positioning method or some auxiliary data type, the positioning server may decide to stop the positioning method or some auxiliary data. Broadcast of the type of auxiliary data. Or do not turn on the broadcast of the auxiliary data of this positioning method.
若停止广播后，还有UE需要辅助数据，则向定位服务器进行单播请求辅助数据。If the UE needs auxiliary data after stopping the broadcast, the unicast request assistance data is sent to the positioning server.
定位服务器根据收到的UE定位参数或者指示信息，进行相应的定位处理，以确定是否进行广播辅助数据，如开启或者维持广播，或者停止广播。当需要辅助数据的UE数量较多时，开启或者维持广播辅助数据，当需要辅助数据的UE的数量较少时，则停止广播辅助数据，具体的，一种情况如S203～S206；另一种情况如S207～S209。The positioning server performs corresponding positioning processing according to the received UE positioning parameter or indication information to determine whether to perform broadcast auxiliary data, such as enabling or maintaining the broadcast, or stopping the broadcast. When the number of UEs requiring assistance data is large, the broadcast assistance data is turned on or maintained, and when the number of UEs requiring the assistance data is small, the broadcast assistance data is stopped. Specifically, one case is S203 to S206; Such as S207 ~ S209.
S203：若需要辅助数据的UE的个数大于预设阈值或者需要辅助数据的UE数目较多时，则定位服务器确定或维持广播辅助数据。S203: If the number of UEs that need the auxiliary data is greater than a preset threshold or the number of UEs that need the auxiliary data is large, the positioning server determines or maintains the broadcast auxiliary data.
具体的，需要定位的UE个数可以为需要某一定位方法或者某一辅助数据类型的辅助数据的UE数目。Specifically, the number of UEs that need to be located may be the number of UEs that need a certain positioning method or auxiliary data of a certain auxiliary data type.
其中确定或维持的含义是，如果没有UE在进行广播，则触发广播辅助数据流程，如果正在广播，则维持该广播状态。The meaning determined or maintained is that if no UE is broadcasting, the broadcast assistance data flow is triggered, and if it is being broadcast, the broadcast state is maintained.
类似的这里需要辅助数据的UE数目的判断可以根据需要某一种定位方法的辅助数据的UE数目进行判断。A similar judgment of the number of UEs requiring assistance data herein may be determined according to the number of UEs that need assistance data of a certain positioning method.
其中，预设阈值的大小可以根据无线资源的多少确定，例如：当无线资源比较富余，预设阈值可以设定的小一些，当无线资源比较稀缺，预设阈值可以设定的大一些，对此，本申请不做限制。这部分可以由定位服务器实现决定。The preset threshold may be determined according to the number of radio resources. For example, when the radio resources are relatively redundant, the preset threshold may be set smaller. When the radio resources are scarce, the preset threshold may be set larger. Therefore, this application does not limit the matter. This part can be determined by the positioning server implementation.
S204：定位服务器向基站发送第二指示信息。S204: The positioning server sends the second indication information to the base station.
其中，第二指示信息用于指示基站广播辅助数据。The second indication information is used to indicate that the base station broadcasts the auxiliary data.
第二指示信息包括但不限于如下实现方式：The second indication information includes but is not limited to the following implementation manners:
一种可能的实现方式，通过向基站发送辅助数据来指示基站采用广播方式向UE发送辅助数据，即，基站接收到定位服务器发送的辅助数据，则意味着定向服务器指示其以广播的方式向UE发送辅助数据。A possible implementation manner, by sending auxiliary data to the base station to indicate that the base station sends the auxiliary data to the UE in a broadcast manner, that is, the base station receives the auxiliary data sent by the positioning server, which means that the directional server instructs the UE to broadcast to the UE. Send auxiliary data.
另一种可能的实现方式，通过某种类型的消息、在某个消息中携带某特定的标识或者在某个消息中某个或某些特定的比特位设定特定的数值，或者通过某个消息以及某个字段等等，以指示接收到该消息的基站采用广播的方式向UE发送辅助数据。可选地，在该种实现方式中，第二指示信息中还可以包括：用于广播的辅助数据。Another possible implementation, by using a certain type of message, carrying a specific identifier in a message, or setting a specific value in a certain bit or bits of a message, or by some A message, a field, and the like, to indicate that the base station that received the message transmits the auxiliary data to the UE in a broadcast manner. Optionally, in this implementation manner, the second indication information may further include: auxiliary data for broadcasting.
这里的第二指示信息具体可以是根据需要某一定位方式的UE数目较多时，而进行对该定位方式的辅助数据的指示或者传输该定位方式的辅助数据。The second indication information herein may specifically be an indication of the auxiliary data of the positioning mode or the auxiliary data for transmitting the positioning mode according to the number of UEs that require a certain positioning mode.
若第二指示信息中包含辅助数据。则不执行S205。If the second indication information includes auxiliary data. Then S205 is not executed.
若第二指示信息中未包含辅助数据。还包括：If the second indication information does not include auxiliary data. Also includes:
S205：定位服务器向基站发送辅助数据。S205: The positioning server sends the auxiliary data to the base station.
S206：基站获取辅助数据。S206: The base station acquires the auxiliary data.
基站获取辅助数据用来向UE进行广播。UE接收到辅助数据后，可以使用辅助数据进行定位计算。The base station acquires the auxiliary data for broadcasting to the UE. After receiving the auxiliary data, the UE can use the auxiliary data for positioning calculation.
其中，一种可能的实现方式：第二指示信息中包含辅助数据，则基站通过第二指示信息获取辅助数据。A possible implementation manner is as follows: the second indication information includes auxiliary data, and the base station acquires the auxiliary data by using the second indication information.
另一种可能的实现方式：基站直接接收定位服务器发送的辅助数据。Another possible implementation manner: the base station directly receives the auxiliary data sent by the positioning server.
S207：若需要辅助数据的UE的个数小于等于预设阈值或者需要辅助数据的UE数目较少时，则确定停止广播辅助数据。S207: If the number of UEs that need auxiliary data is less than or equal to a preset threshold or the number of UEs that need auxiliary data is small, it is determined to stop broadcasting the auxiliary data.
类似的这里需要定位UE数目的判断可以根据需要某一种定位方式的辅助数据的UE数目进行判断。具体的，需要定位的UE个数可以为需要某一定位方法或者某一辅助数据类型的辅助数据的UE数目。Similarly, the judgment of the number of UEs to be located herein may be determined according to the number of UEs that need assistance data of a certain positioning mode. Specifically, the number of UEs that need to be located may be the number of UEs that need a certain positioning method or auxiliary data of a certain auxiliary data type.
当需要辅助数据的UE的个数小于等于预设阈值时，而当前基站正在广播辅助数据，则停止广播辅助数据，可以避免无线资源的浪费。When the number of UEs that need the auxiliary data is less than or equal to the preset threshold, and the current base station is broadcasting the auxiliary data, stopping the broadcast of the auxiliary data may avoid waste of the wireless resources.
此过程也可以为定位服务器实现过程。具体实施时可以不体现该步骤。This process can also be used to locate the server implementation process. This step may not be embodied in the specific implementation.
S208：定位服务器向基站发送第二指示信息。S208: The positioning server sends the second indication information to the base station.
其中，第二指示信息用于指示基站停止广播辅助数据。具体的可以停止某一定位方法或者某一辅助数据类型的辅助数据。The second indication information is used to instruct the base station to stop broadcasting the auxiliary data. Specifically, it is possible to stop a positioning method or auxiliary data of a certain auxiliary data type.
第二指示信息，可以通过某个的消息、在某个消息中携带某特定的字段或标识或者在某个消息中某个或某些特定的比特位设定特定的数值等，以指示接收到该消息的基站停止广播辅助数据。The second indication information may be received by a certain message, carrying a specific field or identifier in a certain message, or setting a specific value in a certain bit or a certain bit of a message, etc., to indicate that the message is received. The base station of the message stops broadcasting the auxiliary data.
第二指示信息可以携带时间等参数，时间可以用于表示在该时间后将停止发送辅助数据。The second indication information may carry parameters such as time, and the time may be used to indicate that the transmission of the auxiliary data will be stopped after the time.
第二指示信息所在的消息也可以用于定位服务器发送给基站用于指示开始或者更新广播辅助数据。The message in which the second indication information is located may also be used by the positioning server to send to the base station for instructing to start or update the broadcast assistance data.
第二指示信息用于停止广播指示时，也可以表示是最后一个数据包指示。表明该数据的最后一个数据包，将停止对该数据的发送。When the second indication information is used to stop the broadcast indication, it may also indicate that it is the last packet indication. Indicates that the last packet of the data will stop sending the data.
第二指示信息可以用于所有辅助数据也可以用于某一定位方法的辅助数据。The second indication information can be used for all auxiliary data as well as auxiliary data for a certain positioning method.
S209：定位服务器向UE发送辅助数据。S209: The positioning server sends the auxiliary data to the UE.
当定位服务器停止向基站发送辅助数据后，基站停止广播辅助数据。若UE还需要辅助数据，则定位服务器以单播的方式向UE发送辅助数据，从而，避免无线资源的浪费。After the positioning server stops transmitting auxiliary data to the base station, the base station stops broadcasting the auxiliary data. If the UE further needs the auxiliary data, the positioning server sends the auxiliary data to the UE in a unicast manner, thereby avoiding waste of the wireless resources.
这里的第二指示信具体可以是根据需要某一定位方法或者某一辅助数据类型的UE数目较少时，而进行对该定位方法或者某一辅助数据类型的辅助数据停止广播传输的指示。The second indication information here may specifically be an indication that the positioning method or the auxiliary data of a certain auxiliary data type stops broadcasting transmission according to a certain positioning method or a small number of UEs of a certain auxiliary data type.
本实施例，通过UE向定位服务器发送第一指示信息，第一指示信息中携带UE的定位参数，以使定位服务器获取UE的定位参数，并根据UE的定位参数，确定需要辅助数据的UE的个数，当需要辅助数据的UE的个数大于预设阈值，则定位服务器确定广播辅助数据，当要辅助数据的UE的个数小于等于预设阈值，则确定停止广播辅助数据，从而，合理利用无线资源，避免无线资源的浪费，提高无线资源的利用率。In this embodiment, the first indication information is sent by the UE to the positioning server, where the first indication information carries the positioning parameter of the UE, so that the positioning server acquires the positioning parameter of the UE, and determines the UE that needs the auxiliary data according to the positioning parameter of the UE. If the number of the UEs that need the auxiliary data is greater than the preset threshold, the positioning server determines the broadcast assistance data, and when the number of the UEs to be assisted data is less than or equal to the preset threshold, determining to stop the broadcast assistance data, thereby, reasonably Use wireless resources to avoid waste of wireless resources and improve utilization of wireless resources.

图3为本申请提供的另一种辅助数据的发送方法的流程示意图，图3与图2所示 实施例不同的是，在图2所示实施例中，定位服务器通过UE发送的第一指示信息获取UE的定位参数，在图3所示实施例中，通过定位服务器向UE发送请求消息，以请求UE发送UE的定位参数，UE向定位服务器发送响应消息，在响应消息中携带UE的定位参数，从而，使得定位服务器获得UE的定位参数，并进行后续处理，如图3所示，本实施例的方法如下：FIG. 3 is a schematic flowchart of another method for sending auxiliary data according to the present application. FIG. 3 is different from the embodiment shown in FIG. 2, in the embodiment shown in FIG. 2, the first indication sent by the positioning server by the UE. In the embodiment shown in FIG. 3, the positioning server sends a request message to the UE to request the UE to send the positioning parameter of the UE, and the UE sends a response message to the positioning server, where the response message carries the positioning of the UE. The parameter is such that the positioning server obtains the positioning parameter of the UE and performs subsequent processing. As shown in FIG. 3, the method in this embodiment is as follows:
S301：定位服务器向UE发送请求消息。S301: The positioning server sends a request message to the UE.
其中，请求消息用于请求UE发送UE的定位参数。The request message is used to request the UE to send the positioning parameter of the UE.
