通信方法以及通信装置
本申请要求于2022年4月29日提交中国专利局，申请号为202210467495.3，发明名称为“通信方法以及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法以及通信装置。
背景技术
定位功能是第五代移动通信技术(5th generation mobile communication technology，5G)新空口的一项重要功能。终端设备的当前服务接入网设备可以为终端设备确定探测参考信号(sounding reference signal，SRS)配置信息，并向终端设备和定位管理设备发送该SRS配置信息。定位管理设备基于该SRS配置信息对终端设备进行定位。因此，如何保障定位功能的正常进行，是值得考虑的问题。
发明内容
本申请提供了一种通信方法以及通信装置，用于保障定位功能的正常进行。
本申请第一方面提供一种通信方法，包括：
第一接入网设备通过第二接入网设备向终端设备发送无线资源控制(radio resource control，RRC)释放消息，以及向第二接入网设备发送第一信息，第一信息用于请求第二接入网设备向第一接入网设备反馈第二接入网设备向终端设备发送RRC释放消息是否成功的信息，RRC释放消息包括终端设备的探测参考信号(sounding reference signal，SRS)配置信息；第一接入网设备接收来自第二接入网设备的第一消息，第一消息用于向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息成功或失败的信息。
由上述技术方案可知，第一接入网设备可以向第二接入网设备发送第一信息。该第一信息用于请求第二接入网设备向第一接入网设备反馈第二接入网设备向终端设备发送RRC释放消息是否成功的信息。而该RRC释放消息包括终端设备的SRS配置信息。或者说，第一信息用于指示第二接入网设备向第一接入网设备反馈：第二接入网设备向终端设备发送配置信息成功或失败的信息；或者，第一信息用于指示第二接入网设备向第一接入网设备反馈：第二接入网设备向终端设备配置SRS成功或失败的信息。然后，第一接入网设备可以接收来自第二接入网设备的第一消息，第一消息用于向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息成功或失败的信息。或者说，第一消息用于向第一接入网设备指示：第二接入网设备向终端设备发送SRS配置信息成功或失败的信息；或者，第一消息用于向第一接入网设备指示：第二接入网设备向终端设备配置SRS成功或失败的信息。从而第一接入网设备可以确定该第二接入网设备向该终端设备发送RRC释放消息是否成功。也就是第一接入网设备确定该终端设备是否获取到该SRS配置信息，再基于该第一消息向定位管理设备发送相应的消息。保证定位管理设备获取到该SRS配置信息后能够对终端设备进行定 位。从而保障定位功能的正常进行。避免SRS配置信息在没有成功配置给终端设备的情况下导致定位管理设备对终端设备的定位失败。还可避免定位管理设备请求接入网设备测量SRS导致接入网设备的资源浪费。进一步的，第一接入网设备通过RRC释放消息下发该SRS配置信息。从而便于实现终端设备在RRC非激活态或RRC空闲态下发送SRS，实现终端设备的低功耗定位。
一种可能的实现方式中，RRC释放消息和第一信息承载于获取UE上下文失败消息中。
在该实现方式中提供了RRC释放消息和第一信息的具体承载载体，从而方便方案的实施。第一接入网设备可以在获取UE上下文失败消息中下发该RRC释放消息和第一信息，从而实现第一接入网设备指示第二接入网设备反馈RRC释放消息的发送情况。便于第一接入网设备确定终端设备对RRC释放消息的接收情况。从而便于第一接入网设备确定该终端设备是否获取到该SRS配置信息，再基于该第一消息向定位管理设备发送相应的消息。保证定位管理设备获取到该SRS配置信息后能够对终端设备进行定位。从而保障定位功能的正常进行。
另一种可能的实现方式中，第一信息包括获取UE上下文失败消息的第一信元，或第一信息包括第一指示信息，第一信元或第一指示信息用于请求第二接入网设备向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息是否成功的信息。

在该实现方式中，如果第一消息反馈第二接入网设备向终端设备发送RRC释放消息成功的信息，则第一接入网设备向定位管理设备发送SRS配置信息。或者换句话说，第二接入网设备配置终端设备的SRS成功，第一接入网设备可以向定位管理设备发送定位信息响应消息。因此，在终端设备获取到该RRC释放消息(包括SRS配置信息)的情况下，第一接入网设备向定位管理设备发送SRS配置信息，从而便于定位管理设备基于该SRS配置信息对终端设备进行定位。从而保障定位功能的正常进行。避免SRS配置信息在没有成功配置给终端设备的情况下导致定位管理设备对终端设备的定位失败。还可避免定位管理设备请求接入网设备测量SRS导致接入网设备的资源浪费。
另一种可能的实现方式中，若第一消息用于向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息失败的信息，方法还包括：
第一接入网设备向定位管理设备发送定位信息失败消息，定位信息失败消息用于指示终端设备的SRS配置失败。
在该实现方式中，如果第一消息反馈第二接入网设备向终端设备发送RRC释放消息失败，则第一接入网设备向定位管理设备发送定位信息失败消息，定位信息失败消息用于指示终端设备的SRS配置失败。或者说，定位信息失败消息用于指示第一接入网设备为终端设备配置SRS失败。或者，定位信息失败消息用于指示第一接入网设备配置终端设备发送SRS失败。也就是说第一接入网设备不能配置终端设备发送SRS或第一接入网设备配置终端设备的SRS失败，第一接入网设备向定位管理设备发送定位信息失败消息。定位管理设备可以确定该SRS配置失败。定位管理设备可以做出相应的措施。例如，定位管理设备可以选择其他定位方法为终端设备进行定位。从而避免在第一接入网设备决定保留UE上下文的情况下，定位管理设备无法获知终端设备的SRS是否成功配置给终端设备。避免在SRS没有成功配置给终端设备的情况下发生定位失败。还可避免定位管理设备请求接入网设备测量SRS导致的资源浪费。

下面先介绍终端设备的三种可能的RRC状态。该三种RRC状态分别为：RRC连接态(RRC connected)、RRC非激活态(RRC inactive)、RRC空闲态(RRC idle)。
RRC连接态：终端设备与接入网设备之间有RRC连接，并为终端设备建立了接入网设备与核心网之间的连接；接入网设备存储有该终端设备的UE上下文。在RRC连接态下接入网设备与终端设备之间能够通过RRC连接发送单播消息。
RRC非激活态：终端设备与接入网设备之间的RRC连接被暂停(suspend)，并为终端设备建立了接入网设备与核心网之间的连接；接入网设备存储有该终端设备的UE上下文。终端设备可以接收广播消息和寻呼消息。其中，寻呼消息是由接入网设备发起的。
RRC空闲态：终端设备与接入网设备之间没有建立RRC连接，也没有为终端设备建立接入网设备与核心网之间的连接。接入网设备上没有该终端设备的UE上下文。终端设备可以接收广播消息和寻呼消息。其中，寻呼消息是由核心网发起的。
在终端设备处于RRC非激活态或RRC空闲态下，且终端设备从最近服务接入网设备移动至新的接入网设备(也可称为当前的服务接入网设备)的情况下，定位管理设备向最近服务接入网设备请求对终端设备进行定位，会涉及到最近服务接入网设备与当前的服务接入网设备之间的协调问题。
下面介绍两种可能的场景：
场景一：终端设备处于RRC非激活态，定位管理设备决定对终端设备进行定位。定位管理设备可以向最近服务接入网设备发送定位信息请求消息。由于终端设备已经移动到当 前的服务接入网设备，因此需要当前的服务接入网设备为终端设备确定SRS配置信息。因此，最近服务接入网设备将该定位管理设备的定位请求发送给当前的服务接入网设备。当前的服务接入网设备为终端设备确定SRS配置信息后，可以将该SRS配置信息发送给最近服务接入网设备。然后，最近接入网设备再向定位管理设备发送该SRS配置信息。从而实现定位管理设备基于该SRS配置信息为终端设备进行定位。
场景二：终端设备处于RRC非激活态，终端设备基于小数据传输(small data transmission，SDT)向定位管理设备发送事件报告消息。当前的服务接入网设备在转发该事件报告的过程中，可以选择保留UE上下文。定位管理设备接收到该事件报告之后，定位管理设备可以向最近服务接入网设备发送定位信息请求消息。然后，最近服务接入网设备向当前的服务接入网设备发送该定位管理设备的定位请求。当前的服务接入网设备为终端设备确定SRS配置信息后，当前的服务接入网设备可以将该SRS配置信息发送给最近服务接入网设备。然后，最近服务接入网设备再向定位管理设备发送该SRS配置信息。从而实现定位管理设备基于该SRS配置信息为终端设备进行定位。
在上述场景一和场景二中，最近服务接入网设备可以通过RRC释放消息向终端设备下发SRS配置信息。最近服务接入网设备向定位管理设备发送该SRS配置信息。但是，在上述场景一或场景二下，最近服务接入网设备通过当前的服务接入网设备向终端设备发送该RRC释放消息。最近服务接入网设备并无法获知该当前的服务接入网设备是否将该RRC释放消息成功发送给终端设备。
因此，在上述场景一和场景二下，若终端设备没有接收到当前的服务接入网设备的SRS配置，则导致终端设备无法发送SRS。而最近服务接入网设备将该SRS配置信息发送给定位管理设备，定位管理设备基于该SRS配置信息对终端设备进行定位，则导致定位功能无法正常进行，无法对终端设备进行定位。另外，定位管理设备请求对应的至少一个接入网设备对终端设备的SRS进行定位测量，则导致接入网设备的资源浪费。
另一方面，当前的服务接入网设备向终端设备发送RRC释放消息。该RRC释放消息包括终端设备的SRS配置信息。当前的服务接入网设备可以确定该终端设备是否成功接收该RRC释放消息。但是当前的服务接入网设备并不能获知该终端设备的SRS是否配置成功。例如，终端设备无法按照该SRS配置信息发送SRS，导致终端设备的SRS配置失败。而最近服务接入网设备将该SRS配置信息发送给定位管理设备，定位管理设备基于该SRS配置信息对终端设备进行定位，则会导致定位功能无法正常进行，无法对终端设备进行定位。
本申请提供了相应的技术方案，用于保障定位功能的正常进行，避免资源的浪费。具体请参阅后文图2和图3所示的实施例的相关介绍。
下面结合具体实施例介绍本申请的技术方案。

其中，定位信息响应(positioning information response)消息包括终端设备的SRS配置信息。
具体的，如果第一消息指示第二接入网设备向终端设备发送RRC释放消息成功的信息，则第一接入网设备可以向定位管理设备发送定位信息响应消息。该定位信息响应消息包括该终端设备的SRS配置信息。也就是说，如果第一接入网设备配置终端设备发送SRS成功或第一接入网设备配置终端设备的SRS成功，第一接入网设备向定位管理设备发送定位信息响应消息。从而便于定位管理设备基于该SRS配置信息对终端设备进行定位。例如，定位管理设备可以选择至少一个接入网设备，并通过该至少一个接入网设备测量终端设备发送的SRS，得到测量结果。然后，该至少一个接入网设备向定位管理设备发送测量结果。定位管理设备基于该测量结果实现对终端设备的定位。
205、若第一消息用于向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息失败的信息，第一接入网设备向定位管理设备发送定位信息失败消息。相应的，定位管理设备接收来自第一接入网设备的定位信息失败消息。
其中，定位信息失败消息用于指示终端设备的SRS配置失败。或者，定位信息失败消息用于指示第一接入网设备为终端设备配置SRS失败。或者，定位信息失败消息用于指示第一接入网设备配置终端设备发送SRS失败。
具体的，如果第一消息指示第二接入网设备向终端设备发送RRC释放消息失败的信息，则第一接入网设备可以向定位管理设备发送定位信息失败消息。该定位信息失败消息用于指示终端设备配置SRS失败。也就是说第一接入网设备不能配置终端设备发送SRS失败或第一接入网设备配置终端设备的SRS失败，第一接入网设备向定位管理设备发送定位信息失败消息。这样定位管理设备可以做出相应的措施。例如，定位管理设备可以选择其他定位方法为终端设备进行定位。从而避免在第一接入网设备决定保留UE上下文的情况下，定位管理设备无法获知终端设备的SRS是否成功配置给终端设备。避免在SRS没有成功配置给终端设备的情况下发生定位失败。还可避免定位管理设备请求接入网设备测量SRS导致的资源浪费。
本申请实施例中，第一接入网设备可以向第二接入网设备发送第一信息，该第一信息用于请求第二接入网设备向第一接入网设备反馈第二接入网设备向终端设备发送RRC释放消息是否成功的信息。而该RRC释放消息包括终端设备的SRS配置信息。第一接入网设备可以接收来自第二接入网设备的第一消息，第一消息用于向第一接入网设备反馈：第二接入网设备向终端设备发送RRC释放消息成功或失败的信息，或第二接入网设备向终端设备发送SRS配置信息成功或失败的信息。这样第一接入网设备可以确定该第二接入网设备向该终端设备发送RRC释放消息是否成功。从而便于第一接入网设备确定该终端设备是否获取到该SRS配置信息。第一接入网设备可以基于该第一消息确定是否向定位管理设备发送该SRS配置信息。从而保障定位管理设备获取到该SRS配置信息后能够对终端设备进行定位。从而保障定位功能的正常进行。避免SRS配置信息在没有成功配置给终端设备的情况下导致定位管理设备对终端设备的定位失败。还可避免定位管理设备请求接入网设备测量SRS导致接入网设备的资源浪费。

另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例所述方法的全部或部分步骤。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
