Description

网络分配向量设置方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及网络分配向量设置方法、网络分配向量设置装置、电子设备和计算机可读存储介质。
背景技术
在现有的Wi-Fi网络中，终端可以接入不同频段下的信道，但是在同一时刻下只能接入一个信道。在接入某个信道之前，需要先检测该信道是否空闲，若该信道空闲，则可以接入，若该信道繁忙，则需要等待一段时间后，才能再次尝试以竞争的方式随机接入该信道。在相关技术中，主要根据对信道的检测结果来设置网络分配向量(Network Allocation Vector，简称NAV)，并根据该网络分配向量确定再次尝试接入该信道所需等待的时长。
随着通信技术的发展，目前的Wi-Fi技术允许终端同时接入多个信道，但是终端仍然只是针对接入一个信道的情况来设置网络分配向量，这难以适应终端同时接入多个信道的场景。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种网络分配向量设置方法的示意流程图。本实施例所示的网络分配向量设置方法可以适用于终端，所述终端可以为手机、平板电脑、可穿戴设备等电子设备，所述终端可以基于Wi-Fi网络通信。
其中，在Wi-Fi网络中可以具有n信道，所述终端可以同时接入n个信道，也可以每次只接入一个信道，以下实施例主要在终端同时接入n个信道的情况下，对技术方案进行示例性描述。其中，n个信道中每个信道的频段可以是不同的，也可以是相同的，例如以n＝为例，3个信道的频段可以分别为2.4GHz、5.8GHz和6-7GHz。
如图1所示，所述网络分配向量设置方法可以包括以下步骤：
在步骤S1中，对所述n个信道中的每个信道进行检测，以确定所述n个信道中被占用的m个繁忙信道，以及所述繁忙信道被占用的时长；
在步骤S2中，根据m个所述时长设置所述n个信道中至少所述m个繁忙信道的网络分配向量，其中，1≤m≤n。
在一个实施例中，终端对于同时接入的n个信道中每个信道可以进行检测，例如可以通过MAC(Media Access Control，介质访问控制)层实体调用物理层实体，分别在每个信道下进行检测。针对某个信道而言，通过检测可以得到该信道的能量检测(Energy Detection，简称ED)值，若能量检测值大于该信道对应的能量阈值，可以确定该信道正在被其他设备占用，该信道为繁忙信道。一般来说能量检测值的单位是dBm，不同的信道带宽及不同的频段下能量阈值可以不同，例如在2.4GHz的频段下20MHz的信道带宽中能量阈值为-82dBm，而在40MHz的频段下能量阈值为-79dBm。
其中，n个信道中可以存在m个繁忙信道，1≤m≤n，也即对于n个信道而言，在n个信道中存在一个繁忙信道或多个信道的情况下，可以根据m个所述时长设置至少所述m个繁忙信道的网络分配向量。而若m＝0，也即在n个信道中不存在繁忙信道的情况下，那么终端可以直接占用每个信道，也就无需设置网络分配向量。
对于繁忙信道，可以进一步获取繁忙信道传输的协议数据单元(physical layer(PHY)protocol data unit，简称PPDU)，并解析协议数据单元遗留信号(Legacy Signal，简称L-SIG)部分，以确定数据帧发送长度，基于该数据帧发送长度，可以确定繁忙信道被占用的时长。
根据本公开的实施例，针对能够同时接入n个信道终端，可以对n个信道中的每个信道进行检测，从而确定n个信道中被占用的m个繁忙信道，以及繁忙信道被占用的时长，进而根据m个时长设置n个信道中至少m个繁忙信道的网络分配向量。
从而在终端同时接入n个信道的场景下，可以根据m个时长设置至少m个繁忙信道的网络分配向量，有利于保证为每个繁忙信道设置的网络分配向量与繁忙信道被占用的时长相适应，进而保证终端根据网络分配向量再次尝试接入信道，可以及时地接入每个信道进行通信，保证对于多个信道整体具有较高的利用率。
可选地，所述终端通过所述n个信道异步通信。其中，异步通信是指接收端在多个信道下接收数据的时间点不相同，本实施例中的终端可以作为发送端，向一个或多个接收端发送数据，也可以作为接收端接收其他发射端发送的数据。
在一个实施例中，终端可以通过n个信道异步通信，例如以n＝3为例，那么终端可以同时接入这3个频段的信道，当终端作为发送端，在每个信道上发送数据的操 作可以不同步进行，当终端作为接收端，在每个信道上接收数据的操作也可以不同步进行。
图2是根据本公开的实施例示出的另一种网络分配向量设置方法的示意流程图。如图2所示，所述根据m个所述时长设置所述n个信道中至少所述m个繁忙信道的网络分配向量包括：
在步骤S21中，根据m个所述时长中第i个时长设置所述m个繁忙信道中第i个繁忙信道的网络分配向量，1≤i≤m。
在一个实施例中，在终端通过n个信道异步通信的情况下，在n个信道中m个繁忙信道上也是异步通信，那么在每个繁忙信道上接收数据或者发送数据的操作并不需要同步，所以终端可以不同时接入每个信道。
因此，可以根据m个时长中第i个时长设置m个繁忙信道中第i个繁忙信道的网络分配向量，也即确定了第i个繁忙信道被占用的时长，即第i个时长，进而可以根据第i个时长设置第i个繁忙信道的网络分配向量，使得第i个繁忙信道的网络分配向量与其被占用的时长相对应，有利于保证终端基于配置的网络分配向量可以等待适当时长，例如等待第i时长，再尝试接入第i个繁忙信道时，该信道已经不繁忙，从而保证及时地接入该信道进行通信。
图3是根据本公开的实施例示出的一种被占用时长与网络分配向量的关系示意图。如图3所示，例如n＝m＝3，其中第1信道被占用的时长为ta，第2信道被占用的时长为tb，第3信道被占用的时长为tc，那么可以基于ta设置第1信道的网络分配向量为NAVa，基于tb设置第2信道的网络分配向量为NAVb，基于tc设置第3信道的网络分配向量为NAVc。
例如终端可以根据网络分配向量NAVa确定下次尝试接入第1信道所需等待的时长，例如所述等待时长为ta，那么可以在等待ta后，第1信道已经不被占用，终端尝试接入(也即监听该信道是否被占用)第1信道即可成功接入第1信道，从而快速占用第1信道，保证终端及时占用第1信道进行通信。同理，还可以保证终端及时地占用第2信道和第3信道进行通信，从而保证对于3个信道整体具有较高的利用率。
可选地，所述终端通过所述n个信道同步通信。
在一个实施例中，终端可以通过n个信道同步通信，例如以n＝3为例，那么终端可以同时接入这3个频段的信道，并且在每个信道上发送数据的操作可以同步进行， 例如终端可以作为发送端在同一时刻在多个信道下发送数据，在每个信道上接收数据的操作也可以同步进行，例如终端可以作为接收端在同一时刻在多个信道下接收数据，其中，接收数据的起始时刻可以相同，接收数据的结束时刻也可以相同。
图4是根据本公开的实施例示出的又一种网络分配向量设置方法的示意流程图。如图4所示，所述根据m个所述时长设置所述n个信道中至少所述m个繁忙信道的网络分配向量包括：
在步骤S22中，确定m个所述时长中的最长时长；
在步骤S23中，根据所述最长时长设置所述n个信道中每个信道的网络分配向量。
在一个实施例中，在终端通过n个信道同步通信的情况下，在n个信道中m个繁忙信道上也是同步通信，那么在每个繁忙信道上接收数据或者发送数据的操作需要同步，需要保证终端同时接入每个信道。
在这种情况下，可以先确定m个时长中的最长时长，然后根据最长时长设置n个信道中每个信道的网络分配向量，使得n个信道中每个信道的网络分配向量都与最长时长相对应，从而保证终端针对每个信道都等待最长时长，再尝试接入信道，以便确定再尝试接入信道时，终端在所有繁忙信道上已经完成了数据发送或接收，当再次接入信道时，可以同时接入所有信道，进而同步进行数据发送或接收，以保证终端在n个信道上同步通信。
图5是根据本公开的实施例示出的另一种被占用时长与网络分配向量的关系示意图。如图5所示，例如n＝m＝3，其中第1信道被占用的时长为ta，第2信道被占用的时长为tb，第3信道被占用的时长为tc，tb为最长时长。那么可以基于tb设置第1信道的网络分配向量为NAVa，第2信道的网络分配向量为NAVb，和第3信道的网络分配向量为NAVc。
那么终端根据网络分配向量NAVa确定下次尝试接入第1信道所需等待的时长为tb，根据网络分配向量NAVb确定下次尝试接入第2信道所需等待的时长为tb，根据网络分配向量NAVc确定下次尝试接入第3信道所需等待的时长也为tb，当终端等待tb后再次尝试接入3个信道时，终端刚好在被占用时长最长的第2信道上完成了通信，从而在接入3个信道后，可以确保下次在3个信道上的通信能够同步进行，并且所需等待的时长不会过长。
图6是根据本公开的实施例示出的又一种网络分配向量设置方法的示意流程图。如图6所示，所述根据m个所述时长设置所述n个信道中至少所述m个繁忙信道的网络分配向量包括：
在步骤S22中，确定m个所述时长中的最长时长；
在步骤S24中，若所述n个信道中存在空闲信道，确定所述终端对所述空闲信道的占用时长是否大于所述最长时长；
在步骤S25中，若所述占用时长大于所述最长时长，根据所述最长时长设置所述n个信道中每个信道的网络分配向量；
在步骤S26中，若所述占用时长不大于所述最长时长，占用所述空闲信道，并根据所述最长时长设置所述m个繁忙信道中每个繁忙信道的网络分配向量。
在一个实施例中，在终端通过n个信道同步通信的情况下，在n个信道中m个繁忙信道上也是同步通信，那么在每个繁忙信道上接收数据或者发送数据的操作需要同步，需要保证终端同时接入每个信道。
而在n个信道中存在m个繁忙信道的情况下，n个信道中还可以存在空闲信道，也即未被其他设备占用的信道，那么终端可以占用该信道，以通过该空闲信道通信。在这种情况下，可以确定m个所述时长中的最长时长，并确定对该空闲信道的占用时长是否大于最长时长。
若占用时长大于最长时长，在当等待最大时长后，可以尝试再次占用m个繁忙信道，但是如果终端仍然在通过空闲信道通信，此时即使能够成功占用m个繁忙信道(例如确定繁忙信道未被占用的情况下)，也并不能保证在m个繁忙信道与在空闲信道上同步通信。
本实施例可以根据最长时长设置n个信道中每个信道的网络分配向量，也即无论m个繁忙信道还是空闲信道，都根据最长时长设置网络分配向量，从而针对空心信道，终端不会立即占用空闲信道，而是等待最长时长后，当尝试再次占用m个繁忙信道时，再占用空闲信道，那么若能够成功占用m个繁忙信道，就可以同时占用m个繁忙信道和空闲信道，也即同时占用n个信道，进而可以在n个信道上同步通信。
若占用时长小于或等于最长时长，即使终端通过空闲信道通信，在等待最长时长后，终端也完成了本次通过空闲信道通，因此后续可以在占用其他信道时，同时再次占用该空闲信道，
本实施例可以先占用该空闲信道，并根据最长时长设置m个繁忙信道中每个繁忙信道的网络分配向量，进而终端针对m个繁忙信道中的每个繁忙信道，都可以等待最长时长后才再次尝试占用，有利于保证同时占用m个繁忙信道。而由于对空闲信道的占用时长小于或等于最长时长，所以在等待最长时长后，终端也完成了本次通过空闲信道通，因此同时占用m个繁忙信道时，也可以同时再次占用该空闲信道，进而在n个信道上同步通信。据此，可以使得终端能够及时地占用空闲信道进行通信，降低空闲信道对应业务的通信时延，并且能够在一定程度上保证终端在n个信道上同步通信。
图7是根据本公开的实施例示出的又一种网络分配向量设置方法的示意流程图。如图7所示，若所述占用时长不大于所述最长时长，所述根据m个所述时长设置所述n个信道中至少所述m个繁忙信道的网络分配向量还包括：
在步骤S27中，计算所述最长时长与所述占用时长的差值；
在步骤S28中，根据所示差值设置所述空闲信道的网络分配向量。
在一个实施例中，在占用时长不大于最长时长的情况下，终端可以占用空闲信道，在本实施例中，可以根据最长时长与占用时长的差值设置空闲信道的网络分配向量NAV0，终端根据NAV0确定的再次尝试占用空闲信道的时长可以等于最长时长与占用时长的差值。
例如最长时长为tb，占用时长为t0，最长时长与占用时长的差值为tb-t0，那么终端在占用空闲信道t0后，可以等待tb-t0才再次尝试占用空闲信道，这使得终端从开始占用空闲信道到再次尝试占用空闲信道的时长为tb，也即最长时长，等于终端再次尝试占用m个繁忙信道等待的时长。
据此，可以保证终端再次尝试占用m个繁忙信道时，终端也再次尝试占用空闲信道，以便终端同时占用m个繁忙信道和空闲信道进行同步通信。
