一种定位消息处理方法、装置、存储介质及电子装置
相关申请的交叉引用
本公开基于2022年06月24日提交的发明名称为“一种定位消息处理方法、装置、存储介质及电子装置”的中国专利申请CN202210734119.6，并且要求该专利申请的优先权，通过引用将其所公开的内容全部并入本公开。
技术领域
本公开实施例涉及通信领域，具体而言，涉及一种定位消息处理方法、装置、存储介质及电子装置。
背景技术
随着5G的发展，高精度的位置服务能力得到进一步增强，上行信号到达时间差(Uplink Time Difference of Arrival，简称为UL-TDOA)定位是5G定位中一个重要的定位方法，其主要原理是利用上行参考信号到基站的时间差来计算位置，UL-TDOA定位使用的协议为3GPP TS 38.455 NRPPa协议(New Radio Positioning Protocol，新空口定位协议A)。UL-TDOA定位是通过核心网的定位管理功能(Location Management Function，简称为LMF)、移动管理功能(Access and Mobility Management Function，简称为AMF)、统一数据管理(Unified Data Management，简称为UDM)等多个网元来执行位置服务业务操作。其中LMF是该定位方法中最为关键的一个网元，主要负责位置的计算并返回定位结果。
LMF并不直接和基站进行交互，而是通过AMF与基站进行交互，LMF将NRPPa协议的内容通过AMF发送给基站，同样基站将NRPPa协议的内容通过AMF返回到LMF。AMF和LMF之间交互的消息分为UE(用户设备)specific消息(以下简称UE消息)和non UE specific消息(以下简称NonUE消息)。
通常一个LMF会有多个相同的消息处理模块，各个模块相互独立，以达到负荷分担提升性能的目的。当AMF将消息发送到LMF后，LMF再将消息分发到具体的消息处理模块。UE消息中直接带有UE相关的信息，LMF可以根据UE的信息将消息分发到对应的模块，而NonUE消息中没有直接的用户信息，不能通过用户信息分发到对应的消息处理模块。
针对相关技术中NonUE消息中没有直接的用户信息，不能通过用户信息分发到对应的消息处理模块，无法保证一次完整的定位流程都在同一个定位模块的问题，尚未提出解决方案。

在一实施例中，所述方法还包括：若确定所述定位消息为所述定位请求消息，解码所述定位请求消息，获取所述定位请求消息中的用户信息，根据所述用户信息将所述定位消息分发到任意一个消息处理队列中，以对所述定位消息进行处理；若所述定位消息为所述UE消息，从所述URL中获取用户信息，根据所述用户信息将所述定位消息分发到对应的消息处理队列中，以对所述定位消息进行处理。
在另一实施例中，在上述步骤S208之前，所述方法还包括：在所述定位消息为TRP响应消息的情况下，以预设时间周期向所述AMF发送TRP请求消息；接收到所述TRP测量响应消息之后，从所述TRP响应消息中获取TRP信息；以预设时间周期对所述TRP信息进行缓存，并记录缓存时间。
在另一实施例中，在以预设时间周期对所述TRP信息进行缓存，并记录缓存时间之后，所述方法还包括：接收定位请求消息，并获取当前时间；判断所述当前时间与所述缓存时间的差值是否在预设时间周期内；在判断结果为是的情况下，不向所述AMF发送所述TRP请求消息；在判断结果为否的情况下，向所述AMF发送所述TRP请求消息，以便接收所述TRP测 量响应消息并更新缓存的所述TRP消息。
本实施例，在UL-TDOA定位中进行NonUE消息的分发与处理，可以解决NonUE消息无法分发到对应定位模块的问题，实现了NonUe消息的分发、缓存以及消息处理。
在收到定位消息后将NonUE消息中的NRPPa信息解码，获取NRPPa中的会话号，从会话号中解析出逻辑号；根据逻辑号将消息发送到消息处理队列上；NonUE携带的NRPPa信息主要是发送接收点(Transmission-Reception Point，简称为TRP)和测量，将TRP信息缓存到内存，TRP为周期性获取；根据NRPPa中的会话号找到对应的定位流程会话号，确保该次消息在同一个会话。本实施例中的NonUE消息具体可以是TRP响应消息或测量响应消息。
当LMF接收到AMF发送过来的消息时首先获取消息中的URL，然后根据URL判断消息的类型；当URL中包含determine-location时为定位请求消息，然后解码定位请求消息，获取消息中的用户信息，然后根据用户信息将消息分发到任意一个消息处理队列；当URL中包含n2-notification时为UE消息，然后从URL中获取用户信息，然后根据定位请求中同样的规则将消息分发到对应的消息处理队列，由于一次定位中的用户信息是一样的，因此可以根据用户信息确保将UE消息发送到同一个消息处理队列；当URL中包含non-ue-n2-notification时为NonUE消息，此时需要先解码NonUE消息，从解码后的判断NonUE消息中是否携带NRPPa的信息；当NonUE消息中有携带NRPPa消息时，解码NRPPa消息，从解码的NRPPa消息中获取并保存NRPPa的会话号Transaction ID。
Transaction ID由消息处理队列产生，由消息处理队列的逻辑号logicNo和transkey组成；根据逻辑号将本次消息发送到对应的消息处理队列。
将收到的TRP响应中的TRP信息进行缓存，由于不是每次定位请求都需要发送TRP请求，因此将TRP请求设为周期发送，周期内将TRP信息缓存在内存中；收到消息后对消息进行解码，判断为TRP响应后，从消息中获取TRP信息并保存在内存中，并记录当前保存时间t1；当收到下一次定位请求后，获取当前时间t2，然后与t1相减，判断是否在缓存周期内，如果超过缓存时间需要重新发送TRP请求，然后清除原有TRP信息并重新保存新的信息。
接收定位请求，发送和接收测量消息并进行定位计算，最后返回定位结果，消息处理队列一般会有多个，主要是为了负荷分担，防止单个消息处理队列出现性能瓶颈；发送测量请求时需要获取当前消息处理队列的逻辑号logicNo和定位流程的会话号transKey，将logicNo左移11位(对应上面描述，不做具体限定)，然后加上transKey组成每次测量请求的Transaction ID，测量请求中需要的TRP信息从缓存中获取；当消息处理队列收到测量响应消息时，先解码消息获取Transaction ID，然后取Transaction ID的低11位得到transKey，根据transKey找到当前的会话；收到测量响应后从消息中获取测量结果，最后根据测量结果计算出位置。
通过本实施例，可以实现UL-TDOA的高并发处理，同时将没有携带任何UE信息的消息准确分发到对应的处理模块中去，保证流程的完整性。
