接收信道功率指示数值的解析方法、设备、以及存储介质
相关申请的交叉引用
本申请基于申请号为202010607400.4、申请日为2020年6月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请实施例涉及但不限于通信技术领域，尤其涉及一种接收信道功率指示数值的解析方法、设备、以及计算机可读存储介质。
背景技术
随着人们生活水平以及居住条件的改善，家庭中对无线网络的需求，越来越普及，这进而导致对Wi-Fi信号的覆盖提出了新的要求，在这种情况下，无线mesh网络(即，无线网格网络)应运而生。无线mesh网络，也称为“多跳(multi-hop)”网络，是一种利用无线链路将多个AP(Access Point,接入点)连接起来的一种星型动态自组织自配置的无线网络，与传统无线局域网相比，无线mesh网络最大的特点就是将骨干网络中的AP通过无线进行连接，是用以解决“最后一公里”的关键技术之一。
而在无线mesh网络中，通常会涉及在不同AP之间的漫游，这就需要应用到无线局域网标准IEEE 802.11k，该标准实现的功能之一是改善漫游决策，其中涉及到对接收信号强度相关的参数RCPI(Received Channel Power Indicator，接收信道功率指示)的解析问题。在实际应用中，RCPI的数值填写、解析有两种算法，一种是IEEE 802.11k规范中定义的，另一种是非规范定义的，这两种方式差异极大，难以兼容与识别。在借助IEEE 802.11k规范引导终端STA(Station，站)对其他特定AP的信号进行测量时，不同厂家的STA，输出的RCPI数值基于以上所述的两种不兼容的方式，导致RCPI数值识别、解析困难，降低了RCPI数值解析的正确率，进而导致终端漫游决策精确度下降。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请实施例提供了一种接收信道功率指示数值的解析方法、设备、以及计算机可读存储介质，能够提高RCPI数值解析的正确率。

本申请的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本申请而了解。本申请的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
附图用来提供对本申请技术方案的进一步理解，并且构成说明书的一部分，与本申请的实施例一起用于解释本申请的技术方案，并不构成对本申请技术方案的限制。

图4是本申请实施例3提供的RCPI数值的解析方法的流程图；以及
图5是本申请实施例4提供的RCPI数值的解析方法的流程图。
具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请实施例提供了一种RCPI数值的解析方法、设备、以及计算机可读存储介质。本申请实施例提供的方案充分利用当前两种解析算法分别存在的不重叠的盲区，或称为不合理区间，基于非此即彼的排除法，利用所获取的RCPI数值所处的数值区间便可以确定合适的解析算法，从而能够兼容对基于两种不同定义输出的RCPI数值进行解析，提高RCPI数 值解析的正确率，进而提高对各种终端漫游决策的支持能力，提升漫游决策精确度。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的用于执行RCPI数值的解析方法的网络拓扑的示意图。在图1的示例中，该网络拓扑包括控制器AP(Controller AP)、多个代理AP(Agent AP)(为简化描述，图1中仅示出来两个代理AP，即，代理AP1和代理AP2)，以及终端STA，例如各厂商支持IEEE 802.11k规范的手机或计算机终端等。该网络拓扑在执行本申请实施例的RCPI数值的解析方法时，由控制器AP发送请求测量连接信号强度的测量请求(例如测量请求帧、或封装了测量请求信息的数据帧)到待测量的STA，STA获得AP信号的RCPI数值并生成测量报告(例如测量报告帧或者封装了测量报告的数据帧)，接着将测量报告发送回控制器AP，以供下一步解析用。另外，在该网络拓扑中，AP节点例如Agent AP1和Agent AP2会定期发送信标(Beacon)帧，以让STA得知该网络的存在，从而调整加入该网络所必要的参数。而移动的节点如STA也会发送探测请求(Probe Request)帧，以扫描所在区内有哪些AP可供使用。AP节点在收到探测请求帧后，会返回探测响应(Probe Response)帧，该探测响应帧和信标帧的内容几乎是一致的，之后利用该探测响应帧中的一些信息，AP节点才会继续发起接入过程。
本申请实施例描述的网络拓扑以及应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域技术人员可知，随着网络拓扑的演变和新应用场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本领域技术人员可以理解的是，图1中示出的各种部件及拓扑结构并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述网络拓扑结构，提出本申请的RCPI数值的解析方法的各个实施例。
实施例1
如图2所示，图2是本申请实施例1提供的RCPI数值的解析方法的流程图，该RCPI数值的解析方法包括但不限于步骤S101、步骤S102、步骤S103以及步骤S104。
步骤S101，向终端发送用于请求测量连接信号强度的测量请求。
在一个实施例中，终端包括各厂商支持IEEE 802.11k规范的STA，如支持IEEE 802.11k规范的手机或计算机终端等。
在一个实施例中，测量请求为测量请求帧、或封装了测量请求的数据帧。
步骤S102，接收终端基于测量请求发送的测量报告，测量报告携带有RCPI数值。
在一个实施例中，测量报告为测量报告帧、或封装了测量报告的数据帧。
步骤S103，根据RCPI数值所处的数值区间确定对应的解析算法。
在一个实施例中，解析算法包括：
(1)标准解析算法：
RSSI＝(RCPI/2)-110；
其中，RSSI为接收信号强度指示。
(2)非标准解析算法：
RSSI＝RCPI-256；
其中，RSSI为接收信号强度指示。
应当理解的是，上述标准解析算法和非标准解析算法同样适用于后续描述的所有实施例。
在正常情况下，测量出来的无线信号的RSSI数值都是负数，只有在一种情况下为0dBm，那就是在理想状态下经过实验测量的结果，0dBm意味着接收方把发射方发射的所有无线信号都接收到了，即无线AP发射多少功率，接收的无线网卡就获得多少功率，这实际中是不可能达到的。而根据以上算法可知，当AP接收到的RCPI数值大于或等于220时，使用标准解析算法解析出来的RSSI数值大于或等于0dBm，信号强度太强，实际中不可能达到，因此这是不合理的，那么就可以判定上报该RCPI数值的终端STA适合非标准解析算法。当AP接收到的RCPI数值小于或等于156，使用非标准解析算法解析出来的RSSI数值为小于或等于-100dBm，信号强度低到这个程度，终端STA通常应当已经掉线了，所以不合理，那么就可以判定上报该RCPI数值的终端STA适合标准解析算法。当AP接收到的RCPI数值大于156且小于220，表明该终端STA并未处于AP的识别区，当次解析使用默认解析算法。后续当终端STA发生位置变化而进入AP的识别区,根据终端STA重新上报的RCPI数值来确定合适的解析算法。
步骤S104,利用确定的解析算法解析RCPI数值。
本申请实施例提供的方案充分利用当前两种解析算法分别存在的不重叠的盲区，或称为不合理区间，基于非此即彼的排除法，利用所获取的RCPI数值所处的数值区间便可以确定合适的解析算法，从而能够兼容对基于两种不同定义输出的RCPI数值进行解析，提高RCPI数值解析的正确率，进而提高对各种终端漫游决策的支持能力，提升漫游决策精确度。
实施例2
如图3所示，图3是本申请实施例2提供的RCPI数值的解析方法的流程图，该RCPI数值的解析方法包括但不限于步骤S201、步骤S202、步骤S203以及步骤S204。
步骤S201，向终端发送用于请求测量连接信号强度的测量请求。
在一个实施例中，终端包括各厂商支持IEEE 802.11k规范的STA，如支持IEEE 802.11k规范的手机或计算机终端等。
在一个实施例中，测量请求为测量请求帧、或封装了测量请求的数据帧。
步骤S202，接收终端基于测量请求发送的测量报告，测量报告携带有RCPI数值。
在一个实施例中，测量报告为测量报告帧、或封装了测量报告的数据帧。
步骤S203，当RCPI数值所处的数值区间的最小值大于预设阈值区间的最大值，确定采用非标准解析算法解析RCPI数值。
在一个实施例中，预设阈值区间为(156,220)。在正常情况下，测量出来的无线信号的RSSI数值都是负数，只有在一种情况下为0dBm，那就是在理想状态下经过实验测量的结果，0dBm意味着接收方把发射方发射的所有无线信号都接收到了，即无线AP发射多少功率，接收的无线网卡就获得多少功率，这实际中是不可能达到的。当AP接收到的RCPI数值大于或等于220时，使用标准解析算法解析出来的RSSI数值大于或等于0dBm，信号强度太强，实际中不可能达到，因此这是不合理的，那么就可以判定上报该RCPI数值的终端STA适合非标准解析算法。
上述阈值区间仅仅是本申请的一个示例，并不构成对本申请保护范围的限制。应当理解的是，本领域技术人员可以根据实际网络状况，适当缩窄上述预设阈值区间。
步骤S204,利用非标准解析算法解析RCPI数值。
本申请实施例提供的方案充分利用当前两种解析算法分别存在的不重叠的盲区，或称为不合理区间，基于非此即彼的排除法，利用所获取的RCPI数值所处的数值区间便可以确定合适的解析算法，从而能够兼容对基于两种不同定义输出的RCPI数值进行解析，提高RCPI数值解析的正确率，进而提高对各种终端漫游决策的支持能力，提升漫游决策精确度。
附加地，再次参考图3，本实施例所述的RCPI数值的解析方法还可包括：
步骤S205,对与RCPI数值对应的终端标记非标准解析算法标识，保存标记有标准解析算法标识的终端的终端信息。
在一个实施例中，终端信息包括终端的mac地址。
本申请实施例通过对终端进行标记，使得能够在后续RCPI数值的解析过程中，根据保存的终端信息所对应的标识，直接应用非标准解析算法来解析终端上报的RCPI数值，从而提高RCPI数值的解析效率。
实施例3
如图4所示，图4是本申请实施例3提供的RCPI数值的解析方法的流程图，该RCPI 数值的解析方法包括但不限于步骤S301、步骤S302、步骤S303以及步骤S304。
步骤S301，向终端发送用于请求测量连接信号强度的测量请求。
在一个实施例中，终端包括各厂商支持IEEE 802.11k规范的STA，如支持IEEE 802.11k规范的手机或计算机终端等。
在一个实施例中，测量请求为测量请求帧、或封装了测量请求的数据帧。
步骤S302，接收终端基于测量请求发送的测量报告，测量报告携带有RCPI数值。
在一个实施例中，测量报告为测量报告帧、或封装了测量报告的数据帧。
步骤S303，当RCPI数值所处的数值区间的最大值小于预设阈值区间的最小值，确定采用标准解析算法解析RCPI数值。
在一个实施例中，预设阈值区间为(156,220)。在正常情况下，测量出来的无线信号的RSSI数值都是负数，并且RSSI数值越小，说明信号强度越弱。即无线AP发射多少功率，接收的无线网卡就获得多少功率，这实际中是不可能达到的。当AP接收到的RCPI数值小于或等于156，使用非标准解析算法解析出来的RSSI数值为小于或等于-100dBm，信号强度低到这个程度，终端STA通常应当已经掉线了，所以不合理，那么就可以判定上报该RCPI数值的终端STA适合标准解析算法。
上述阈值区间仅仅是本申请的一个示例，并不构成对本申请保护范围的限制。应当理解的是，本领域技术人员可以根据实际网络状况，适当缩窄上述预设阈值区间。
步骤S304,利用标准解析算法解析RCPI数值。
本申请实施例提供的方案充分利用当前两种解析算法分别存在的不重叠的盲区，或称为不合理区间，基于非此即彼的排除法，利用所获取的RCPI数值所处的数值区间便可以确定合适的解析算法，从而能够兼容对基于两种不同定义输出的RCPI数值进行解析，提高RCPI数值解析的正确率，进而提高对各种终端漫游决策的支持能力，提升漫游决策精确度。
附加地，再次参考图4，本实施例所述的RCPI数值的解析方法还可包括：
步骤S305,对与RCPI数值对应的终端标记标准解析算法标识，保存标记有标准解析算法标识的终端的终端信息。
在一个实施例中，终端信息包括终端的mac地址。
本申请实施例通过对终端进行标记，使得能够在后续RCPI数值的解析过程中，根据保存的终端信息所对应的标识，直接应用标准解析算法来解析终端上报的RCPI数值，从而提高RCPI数值的解析效率。
实施例4
如图5所示，图5是本申请实施例4提供的RCPI数值的解析方法的流程图，该RCPI 数值的解析方法包括但不限于步骤S401、步骤S402、步骤S403以及步骤S404。
步骤S401，向终端发送用于请求测量连接信号强度的测量请求。
在一个实施例中，终端包括各厂商支持IEEE 802.11k规范的STA，如支持IEEE 802.11k规范的手机或计算机终端等。
在一个实施例中，测量请求为测量请求帧、或封装了测量请求的数据帧。
步骤S402，接收终端基于测量请求发送的测量报告，测量报告携带有RCPI数值。
在一个实施例中，测量报告为测量报告帧、或封装了测量报告的数据帧。
步骤S403，当RCPI数值所处的数值区间为预设阈值区间，确定采用非标准解析算法或标准解析算法解析RCPI数值。
在一个实施例中，预设阈值区间为(156，220)。当AP接收到的RCPI数值大于156且小于220，表明该终端STA并未处于AP的识别区，当次解析使用默认解析算法，两种算法都可以作为默认解析算法使用。后续当终端STA发生位置变化而进入AP的识别区,根据终端STA重新上报的RCPI数值来确定合适的解析算法。
上述阈值区间仅仅是本申请的一个示例，并不构成对本申请保护范围的限制。应当理解的是，本领域技术人员可以根据实际网络状况，适当缩窄上述预设阈值区间。
步骤S404,利用非标准解析算法或标准解析算法解析RCPI数值。
在一个实施例中，一般使用非标准解析算法，一方面是使用非标准解析算法的厂商更普遍，另一方面使用标准解析算法的终端更容易被识别并标记，这样如果出现标记错误，更容易被纠正。
本申请实施例提供的方案充分利用当前两种解析算法分别存在的不重叠的盲区，或称为不合理区间，基于非此即彼的排除法，利用所获取的RCPI数值所处的数值区间便可以确定合适的解析算法，从而能够兼容对基于两种不同定义输出的RCPI数值进行解析，提高RCPI数值解析的正确率，进而提高对各种终端漫游决策的支持能力，提升漫游决策精确度。
