Description

确定空间复用的方法及装置 技术领域
本发明实施例涉及通信技术，尤其涉及一种确定空间复用的方法及装置。
背景技术
随着无线局域网的快速发展，移动用户数量持续增长，信道资源变得愈发紧张。
现有技术中，为了提高信道资源利用率，在无线保真(Wireless-Fidelity，简称WiFi)技术中，通过在WiFi消息的物理头部分添加基本服务集标识(Basic Service Set Identification，简称BSSID)信息，以支持空间复用。站点(Station，简称STA)可以通过侦听WiFi消息物理头中的BSSID信息(具体可以是根据BSSID计算的短标识)来确定所述消息是否来自其所属的基本服务集(Basic Service Set，简称BSS)，如果是，则不再考虑空间复用；如果不是，则可以考虑空间复用。具体来说，当STA听到一个不是其所属的基本服务集内的节点发送的帧且此帧的接收功率小于-62dBm时，就忽略此帧，即认为信道仍空闲，以实现空间复用。
但是，一些基本控制帧(一类MAC帧)只能通过具有传统结构的物理帧发送，传统的设备才可以识别接收。而采用现有技术中的方法，由于物理帧的物理头部分要添加BSSID信息，导致传统的设备无法听懂，影响设备的兼容性。因此为了兼容性，控制帧仍需要保持原有的物理帧格式发送，即不能在物理头添加BSSID信息，侦听者也就不能通过物理头判断一个控制帧是否来自本基本服务集。由于控制帧都是采用最低速率传输，与物理头的传输速率一致，因此STA能解析出一个帧的物理头的情况下也能解析出物理头后面承载的控制帧，因而有可能从控制帧的MAC头中获得BSSID信息。然后，在历史上，为了使控制帧尽量短小以提高频谱利用率，控制帧中并不总是包含BSSID信息。如此一来，控制帧支持空间复用 就出现了障碍。

为了提高信道的资源利用率，在新的WiFi通信标准中，空间复用技术将被支持。为了在保证正常通信的基础上，使信道资源得到最大限度的利用，现有技术提出在传送的物理帧的物理头部分添加基本服务集标识(Basic Service Set Identification，简称BSSID)信息，具体来说是根据BSSID计算出的一个短标识，被称为BSS颜色(BSS Color)，用以帮助设备确定在听到一个接收功率低于规定阈值的帧时是否可以实施空间复用。但是，这种方式不能实施于基本控制帧，否则会导致传统设备无法识别某些基本控制帧，影响设备的兼容性。
因此，本发明实施例提供一种确定空间复用的方法及装置。通过第一站点STA接收接入点AP发送的媒体接入控制MAC地址列表，所述MAC地址列表包含与所述第一STA属于同一个基本服务集BSS中的所有第二STA的MAC地址；当所述第一STA监听到其它STA发出的消息时，所述第一STA将所述消息的地址信息(接收地址和/或发送地址)与所述MAC地址列表中的MAC地址进行匹配；当所述消息的地址信息与所述MAC地址列表的任一MAC地址均不同，且，与所述第一STA的MAC地址也不同时，则所述第一STA确定所述消息并非是本BSS中的STA发出的消息，所述第一STA可以进行空间复用。采用本发明实施例提供的确定空间复用的方法和装置，所述第一STA能够获取到与所述第一STA属于同一个BSS的除所述第一STA之外的所有STA的的MAC地址，并将所述第一消息的地址信息与所述MAC地址列表中的MAC地址进行匹配，使得所述第一STA通过直接监听所述第一消息中的地址消息就可以判断所述第一消息是否是本BSS中的消息，从而判断所述第一STA是否可以进行空间复用；本发明实施例提供的确定空间复用的方法和装置，无需改变所述第一消息的物理头结构，能够保证传统设备也可以识别所述第一消息，提高设备的兼容性。
下面以具体地实施例对本发明的技术方案进行详细说明。下述几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。

具体地，所述高效无线保真HEW STA是指支持802.11ax的STA。所述STA首先与所述AP进行关联，所述第一STA在与所述AP进行关联的过程中发送所述指示消息。所述AP只有在收到所述指示消息后才会向所述STA发送所述MAC地址列表。
S102：当所述第一STA监听到第一消息，所述第一消息的地址信息与所述MAC地址列表的任一MAC地址均不同，且，与所述第一STA的MAC地址不同，则确定所述第一STA进行空间复用，所述地址信息为接收所述第一消息的设备的地址和/或发送所述第一消息的设备的地址。
当其它STA或AP发送或接收所述第一消息时，所述第一STA通过监听发送或接收所述第一消息的设备的地址，如果所述地址与所述MAC地址列表中的任一MAC地址相同，或者所述接收地址与所述第一STA的MAC地址相同，则说明所述消息是与所述第一STA同属于一个BSS的STA或AP发送或接收。此时，为了防止影响消息的发送或接收，确定所述第一STA不进行空间复用。如果所述接收地址和/或发送地址与所述MAC地址列表中的任一MAC地址均不相同，且，与所述接收地址与所述第一STA的MAC地址相同，则说明所述消息不是与所述第一STA同属于一个BSS的STA或AP发送或接收，此时，所述第一STA可以进行空间复用。具体地，本发明实施例可以用于保证所述第一STA在空间复用过程中不影响其它设备的数据接收，是所述第一STA实施空间复用的必备条件之一。但是，在具体使用过程中，由于空间复用的成功实施还需要 受其它条件限制，例如：接收功率不能大于-62dBm。因此，所述第一STA最终是否可以成功实施空间复用，还需要根据其它的条件决定。
本发明实施例一提供的确定空间复用的方法，通过第一站点STA接收接入点AP发送的媒体接入控制MAC地址列表，其中，所述MAC地址列表包含与所述第一STA属于同一个基本服务集BSS中的除所述第一STA之外的所有STA的的MAC地址；当所述第一STA监听到第一消息，所述第一消息的地址信息与所述MAC地址列表的任一MAC地址均不同，且，与所述第一STA的MAC地址不同时，则确定所述第一STA进行空间复用，所述地址信息为接收所述第一消息的设备的地址和/或发送所述第一消息的设备的地址。采用本发明实施例提供的确定空间复用的方法，所述第一STA能够获取到与所述第一STA属于同一个BSS的所有其它STA的MAC地址，并将所述第一消息的地址信息与所述其它STA的MAC地址进行匹配，使得所述第一STA通过直接监听所述第一消息中的地址消息就可以判断所述第一消息是否是本BSS中的消息，从而判断所述第一STA是否可以进行空间复用；本发明实施例提供的确定空间复用的方法，无需改变所述第一消息的物理头结构，能够保证传统设备也可以识别所述第一消息，提高设备的兼容性。
在上述实施例中，对于第一站点STA如何接收接入点AP发送的媒体接入控制MAC地址列表，包括但不限于下述四种可能的实现方式：其中，第一种实现方式如图2所示，第二种实现方式如图3所示，第三种实现方式如图4所示。
图2为本发明实施例提供的确定空间复用的方法中第一STA与AP的第一种交互方式的示意图。请参阅图2，所述第一STA接收AP发送的MAC地址列表的第一种实现方式如下：
所述第一STA与所述AP进行四步握手过程中，接收所述AP发送的四步握手消息三，所述四步握手消息三中包含所述MAC地址列表。
具体的，每一个STA在与所述AP进行成功关联后，还需要基于802.11认证协议与所述AP进行802.11x认证。认证过程中，所述AP将所述MAC地址列表发送给所述第一STA。具体地，所述AP与所述第一STA双方经过认证后生成会话主密钥(Pairwise Master Key，简称PMK)。所述认证 过程包括四步握手，其中，四步握手消息一和四步握手消息二是所述第一STA及所述AP之间在PMK基础上协商临时会话秘钥(Pairwise Transient Key，简称PTK)的过程。如果这一步协商成功，则所述第一STA成功连接到所述AP，如果失败，则所述第一STA不能接入所述AP，所述AP不会记录所述第一STA的MAC地址。
进一步地，当有新的STA与所述AP建立关联，或者有STA与所述AP解除关联时，为了保证所述第一STA能够获取到最新的包括了所有所述第二STA的MAC地址的MAC地址列表，所述第一STA接收所述AP发送的四步握手消息三之后，还包括：
所述第一STA接收组临时秘钥(Group Transient Key，简称GTK)握手消息一，所述GTK握手消息一中包含更新后的所述MAC地址列表。
当有新的STA与所述AP建立关联，或者有STA与所述AP解除关联时，所述AP会更新所述GTK。因此，所述AP需要依次向仍处于本BSS内的STA进行GTK握手交互，所述第一STA即在接收所述GTK握手消息一时获取到更新后的所述MAC地址列表。
图3为本发明实施例提供的确定空间复用的方法中第一STA与AP的第二种交互方式的示意图。请参阅图3，所述第一STA接收AP发送的MAC地址列表的第二种实现方式如下：
所述第一STA与所述AP完成四步握手过程后，接收所述AP发送的所述MAC地址列表。
所述第一STA接收AP发送的MAC地址列表的第二种实现方式与第一种实现方式的区别在于：所述第一STA不在四步握手过程中接收所述MAC地址列表，而是在完成所述四步握手过程后，单独接收所述MAC地址列表信息。
同样地，为了保证所述第一STA能够获取到最新的包括了所有所述第二STA的MAC地址的MAC地址列表，还包括：
所述第一STA与所述AP进行GTK握手过程完成后，接收所述AP发送的更新后的所述MAC地址列表。
当所述STA在正确收到更新后的所述MAC地址列表后立即向所述AP发送一个确认符(Acknowledgement，简称ACK)消息，表示成功接收 到更新后的所述MAC地址列表。
图4为本发明实施例提供的确定空间复用的方法中第一STA与AP的第三种交互方式的示意图。请同时参阅图4，所述第一STA接收AP发送的MAC地址列表的第三种实现方式如下：
所述第一STA接收所述AP发送的广播消息，所述广播消息中包含所述MAC地址列表。
具体地，所述MAC地址列表通过广播消息的方式发送，所述第一STA通过接收所述广播消息获取到所述MAC地址列表。
进一步地，为了提高系统的资源利用率，所述第一STA接收AP发送的广播消息之前，还包括：
所述第一STA根据接收的信标帧中的指示信息，确定接收所述AP发送的所述广播消息。
具体地，所述信标帧中的指示信息用于指示所述广播消息中包含更新后的所述MAC地址列表；或者，指示所述MAC地址列表的更新计数值；或者，指示包含更新后的所述MAC地址列表的所述广播消息的发送周期。
其中，所述指示信息可以具体指示在所述信标帧之后的广播消息是否包括更新后的所述MAC地址列表；如果有，则所述第一STA做好接收准备，如果没有，则无需接收。
或者，所述指示信息可以具体指示所述MAC地址列表的更新计数值，当所述指示信息中包含所述更新计数值时，表示所述信标帧后面有更新后的所述MAC地址列表。
具体地，所述更新计数值是一个整数，初始值任意。每当所述MAC地址列表发生变化时(有STA加入或者离开)，所述计数值发生变化，例如加一或者减一。当所述STA侦听到所述信标帧后，根据自己记录的更新计数值确定是否需要接收所述信标帧后面的广播消息。如果所述信标帧中的更新计数值与自己记录的更新计数值不一致，则接收后面的广播消息；否则，无需接收所述广播消息。
或者，所述指示信息还可以具体指示所述广播消息的发送周期，所述广播消息中包括更新后的所述MAC地址列表。
由于STA的进入和离开不是很频繁，所述MAC地址列表的变化就不 会很频繁，因此所述AP不需要在每个信标帧后面都广播发送更新后的MAC地址列表。同时，由于所述AP会周期性地广播信标帧，为了提高资源利用率，可以设置为每隔几个信标帧(例如：每隔3个或10个信标帧)周期性地发送所述广播消息。其中，所述广播消息的发送周期可以根据实际需要进行确定，在此不做限定。具体地，还可以在所述信标帧中使用计数器来表示所述广播信息的发送周期，用以表示更新所述MAC地址列表的剩余时间(例如：再经过多少个信标帧之后会广播发送更新后的所述MAC地址列表)。
进一步地，为了使所述广播消息的长度变短，以提高消息的发送效率，所述广播消息中还可以只携带变化的STA的MAC地址信息。即，所述广播消息中只包含新进入的和新离开的STA的MAC地址信息。
所述第三种实现方式可以单独使用，也可以与所述第一、二或其它实现方式结合使用。例如，所述第一STA首次接收所述MAC地址列表时，可以采用所述第一种或第二种实现方式，当需要接收更新后的MAC地址列表时，可以通过所述第三种实现方式来实现。
图5为本发明实施例提供的确定空间复用的方法中第一STA与AP的第四种交互方式的示意图。请同时参阅图5，所述第一STA接收AP发送的MAC地址列表的第四种实现方式如下：
所述第一STA接收AP发送的MAC地址列表之前，还包括：
所述第一STA向所述AP发送MAC地址列表请求消息。
具体地，所述第一STA可以在关联到所述AP后(成功接入，不一定要经过认证)在任意时候向所述AP发送所述MAC地址列表请求信息。例如：所述STA在从所述AP获得所述GTK的时候就可以向AP发送MAC地址列表请求消息，或者周期性地向AP发送MAC地址列表请求消息。
其中，所述第四种实现方式可以与其他三种实现方式结合使用。以所述第三种实现方式可以与所述第四实现方式相结合为例，具体地，当所述第一STA为新加入所述BSS的STA，且第三种实现方式中的所述广播消息中只携带变化的STA的MAC地址信息时，新加入的所述第一STA无法得知所述BSS中的所有所述第二STA的MAC地址，即可采用所述第四种实现方式，向所述AP发送MAC地址列表请求消息。在其它实现方 式中，也可以先采用所述第四种实现方式，由所述第一STA向所述AP发送MAC地址列表请求消息后再接收AP发送的MAC地址列表。
具体地，在所述第一STA采用上述各实现方式接收到所述AP发送的MAC地址列表之后，所述第一STA可以对所述MAC地址列表进行排序，以便在后续使用MAC地址列表时可以进行快速查找。
图6为本发明确定空间复用的方法实施例二的流程示意图。请参阅图6，本发明实施例一的执行主体是接入点AP，本发明实施例二提供的确定空间复用的方法如下：
S601：接入点AP获取媒体接入控制MAC地址列表，所述MAC地址列表包含与第一STA属于同一个基本服务集BSS中的除所述第一STA之外的所有STA的的MAC地址。
具体地，每个所述除所述第一STA之外的所有STA与所述接入点关联后，所述接入点AP记录所述除所述第一STA之外的所有STA的的MAC地址，以形成所述MAC地址列表。
S602：接入点AP向第一站点STA发送所述MAC地址列表，以使所述第一STA根据所述MAC地址列表确定进行空间复用。
由于只有高效无线保真(High Efficiency WLAN，简称HEW)STA才能支持空间复用，因此，在所述接入点AP向第一站点STA发送所述MAC地址列表之前，还包括：
所述AP接收所述第一STA发送的指示消息，所述指示消息用于指示所述第一STA为高效无线保真HEW STA。
具体地，在所述AP接收所述第一STA发送的指示消息前，所述第一STA首先与所述AP进行关联，所述AP在所述第一STA与所述AP进行关联的过程中接收所述指示消息，并只在收到所述指示消息后才会向所述STA发送所述MAC地址列表。
