目前，随着更多的人使用无线局域网(Wireless Local Area Network，简称为WLAN)进行数据通信，WLAN网络负载也在不断加重，WLAN网络的效率会出现明显下降的趋势，单纯提高速率并不能解决该问题，为解决WLAN网络效率问题，在相关技术中，提出了并行多用户数据传输，其中，该并行多用户数据传输技术包括多用户多输入多输出(Multi-User Multiple Input Multiple Output，简称为MU-MIMO)技术(空域多址)，正交频分多址(Orthogonal Frequency Division Multiple Access，简称为OFDMA)技术(频域多址)及IDMA(Interleave-Division Multiple-Access)技术(码分域多址)。图1是相关技术中WLAN基本服务集的结构示意图，如图1所示，在WLAN中，一个接入点站点(Access Point，简称为AP)以及与该AP相关联的多个非接入点站点(non-AP Station，简称non-AP STA)组成了一个基本服务集(basic service set，简称为BSS)。WLAN中所说的并行多用户数据传输一般为多个次节点同时向主节点发送数据，或者主节点同时给多个次节点发送数据，一般的，主节点为AP或特殊能力non-AP STA，次节点为一般non-AP STA。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明实施例。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在相关技术中，WLAN网络在使用OFDMA/FDMA等并行技术进行数据传输时遇到了一些问题，这是由下述的几个WLAN的特点引起的。
一是WLAN工作于免授权频段，站点相互竞争发送的数据很可能冲突，传统WLAN可以使用控制帧对信道资源进行预约从而保护数据传输，具体的可以使用RTS(request to send)和CTS(clear to send)帧交互预约信道时间，即预约一个传输机会TXOP(transmission opportunity)，上述RTS/CTS帧中携带有将要进行的数据传输的持续时间指示，该指示可以发送RTS/CTS站点周围的旁听站点在持续时间内不竞争信道。为了保证公平性，上述预约的TXOP的时间长度不是随意设置的，而是跟将要传输的数据的QoS参数有关，具体的跟数据的接入类别(Access Category，简称为AC)有关，不同的AC具有不同的TXOP时间长度限制。并行数据传输涉及到多个站点数据的发送，还可能涉及多个接入类别数据的发送，发送冲突的概率更大。
二是WLAN中，既存在着早期的设备(legacy STA，可以称之为一类设备)，也存在支持新特性的设备(例如，支持HEW小组定义的新特性的设备，可以称之为二类设备)，新设备后向兼容早期的设备，两种设备在网络中共存，然而在相关技术中并不存在对应的兼容机制，用于支持并行发送一类设备和二类设备的数据。
三是WLAN特殊的信道使用规则。标准定义了最小的基本带宽，例如20MHz，所有数据的发送带宽必须为基本带宽的2的n次幂倍；并且一个BSS必须选择一个主信道，例如一个BSS的工作带宽为80MHz，包括四个20MHz的子信道，其中一个20MHz子信道作为网络的主信道，80MHz内的其他子信道为辅信道，数据发送不仅要满足协议信道化方案带宽的要求，而且每次发送都必须包含主信道，所有设备也在主信道检测信号，根据主信道检测结果判断信道状态，并进行数据接收。可以看出，站点是通过主信道的载波监听机制来触发数据接收的，若主节点直接使用OFDMA进行并行传输，那么所有次节点只能检测并接收包含主信道的数据，次节点无法得知单独的辅信道上的数据发送，造成数据发送的失败。
针对相关技术中的在无线局域网中使用并行传输技术存在的上述问题，基于对上述问题的分析得出，主要是在并行传输前缺乏有效的并行链路建立过程，基于此，在本实施例中，提供了一种并行传输链路的建立方案，以及基于该建立的并行传输链路进行并行数据传输。
在本实施例中提供了一种并行数据传输处理方法，图2是根据本发明实施例的并行数据传输处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，确定用于进行并行数据传输的多个次节点的节点类型，其中，该节点类型包括支持消息并行处理的二类次节点(同上述二类设备)；
步骤S204，依据节点类型确定用于协商并行数据传输的各个次节点资源的资源协商方式；
步骤S206，依据确定的资源协商方式确定分别对应于多个次节点的对应资源；
步骤S208，依据该对应资源对多个次节点进行并行数据传输处理。
通过上述步骤，对于在网络中用于并行数据传输的基本服务集的主节点而言，先通过依据节点类型确定资源协商方式，之后，依据确定的资源协商方式对进行并行数据传输的多个次节点确定分别对应的对应资源，依据确定的对应资源进行并行数据传输处理，分别对用于并行数据传输的节点确定对应的对应资源，有效地避免了次节点间的干扰，依据节点类型确定对应资源，有效地实现了不同次节点间的兼容，即通过上述并行数据传输链路的建立，不仅解决了相关技术中存在的由于WLAN自身的特点并不能建立有效并行传输链路，因而使得WLAN网络无法直接进行并行数据传输的问题，进而达到了不仅能够有效避免并行传输受到干扰，以及能够有效兼容网络新旧设备，有效提高网络效率的效果。
上述处理包括并行传输链路的建立以及基于该建立的并行传输链路进行的并行数据传输，可以采用以下执行步骤：主节点获取传输机会，向不支持消息并行处理的一类次节点(同上述一类设备)发送一类建立请求帧并接收一类次节点发送的一类建立响应帧；和/或，主节点向二类次节点发送一类建立请求帧或二类建立请求帧，并接收二类次节点发送的一类建立响应帧或二类建立响应帧；主节点向上述次节点发送并行无线帧，并接收上述次节点发送的上述并行无线帧的响应帧。
其中，上述一类建立请求帧、一类建立响应帧、二类建立请求帧及二类建立响应帧用于上述并行无线帧发送前的传输建立过程，一类建立请求帧和一类建立响应帧为能被主节点、一类次节点和二类次节点所解析的帧，二类建立请求帧和二类建立响应帧为能被主节点和二类次节点所解析的帧。其中，上述一类建立请求帧、一类建立响应帧、二类建立请求帧及二类建立响应帧的发送频带包括网络主信道。上述主节点向次节点发送并行无线帧，是指主节点使用不同的资源(例如，包括以下至少之一：频域资源、码分域资源、空域资源)在同一时刻向多个节点传输数据帧。
下面结合实施场景对应的具体类型帧进行说明。
针对并行数据传输所对应的场景的不同，对应的资源协商方式也可以不同，例如，在多个次节点的节点类型还包括不支持消息并行处理的一类次节点的情况下，确定对一类次节点与二类次节点采用分别单独协商资源的资源协商方式；在多个次节点的节点类型仅包括支持消息并行处理的二类次节点的情况下，确定对二类次节点采用分别单独协商资源的资源协商方式；在多个次节点的节点类型仅包括支持消息并行处理的二类次节点的情况下，对二类次节点采用同时并行协商的资源协商方式。
针对并行数据传输所对应的场景的不同，依据确定的资源协商方式确定用于进行并行数据传输的分别对应于多个次节点的对应资源也可以采用不同的处理方式，具体地，该多个次节点的节点类型可以为包括一类次节点和二类次节点的情况，也可以为仅包括二类次节点的情况。下面分别说明。
例如，在该多个次节点的节点类型还包括不支持消息并行处理的一类次节点的情况下，主节点可以在确定一类次节点在主信道上的对应资源后，确定二类次节点的对应资源，其中，主信道上的数据传输时间决定并行数据传输在辅信道上的传输时间；实施时，可以采用以下处理方式：主节点在确定一类次节点在主信道上的对应资源后，向二类次节点发送用于请求数据传输的请求消息，其中，向二类次节点发送的请求消息中携带有除一类次节点所占用的资源外的第一资源范围信息；依据二类次节点反馈 的响应消息确定二类次节点的对应资源，其中，二类次节点反馈的响应消息中携带有二类次节点依据第一资源范围信息选择的二类次节点的对应资源。
其中，该主节点向二类次节点发送的请求消息可以包括以下至少之一：单播请求发送RTS帧、单播预定帧、多播预定帧，其中，单播RTS帧中的保留指示位指示携带的第一资源范围信息，单播预定帧或多播预定帧的信息域指示携带的第一资源范围信息；二类次节点反馈的响应消息为单播允许发送CTS帧或单播预定响应帧，其中，二类次节点反馈的单播CTS帧中的保留指示位指示携带的二类次节点选择的对应资源，该单播预定响应帧的信息域指示携带的该二类次节点选择的对应资源。
基于上述资源协商方式对应的场景，以上述并行传输链路的建立过程中所采用以下具体类型帧为例进行说明。该一类建立请求帧为请求发送帧，对应地，该一类次节点向主节点发送的一类建立响应帧为允许发送帧。向二类次节点发送的一类建立请求帧为包含频段范围指示信息的请求发送帧，对应地，该二类次节点发送的一类建立响应帧为包含频段范围指示信息的允许发送帧。
以上述资源为频域资源为例，上述请求发送帧包含的频段范围指示信息指示了主节点指示给二类次节点使用的频段范围，上述允许发送帧包含的频段范围指示信息指示了二类次节点确认的频段范围。其中，该允许发送帧包含的频段范围指示信息指示的频段范围，为请求发送帧包含的频段范围指示信息指示的频段范围的子集。较优地，频段范围指示信息可以设置在请求发送帧和允许发送帧中的物理层或MAC层信令域中。
上述二类建立请求帧可以为并行传输请求帧，且包含一个或多个二类次节点信息时，该二类次节点信息至少包含有频段范围指示信息及节点标识信息；上述二类建立响应帧可以为并行传输响应帧，且至少包含频段范围指示信息。其中，上述频段范围指示信息指示了频段的起始位置和带宽信息，或指示了频段的临时主信道位置和带宽信息，或指示了子信道列表信息，或指示了临时主信道位置信息。
其中，上述临时主信道位置信息指示了次节点在一次并行传输时临时使用的主信道的位置。上述并行无线帧中可以包含多个次节点的数据，且在发送给二类次节点的数据中包含有响应参数调整指示信息。上述响应参数调整指示信息由主节点按照预定义的基准来确定。
优选的，当该并行无线帧中还包含一类次节点的数据时，上述响应参数调整指示信息由主节点按照上述一类次节点的响应参数作为基准来确定。其中，上述响应参数调整指示信息至少包含下述信息的一项：功率调整信息、立即响应发送时间点调整信 息、载波频率偏移预调整信息。较优地，上述响应参数调整指示信息可以设置在数据的MAC层帧头部分和/或物理层帧头部分。
再例如，在该多个次节点的节点类型仅包括支持消息并行处理的二类次节点的情况下，依据确定的资源协商方式确定分别对应于多个次节点的对应资源。可以采用以下处理方式，需要指出的是，与上述还包括不支持消息并行处理的一类次节点的情况存在相似的处理在此不再赘述：
主节点向二类次节点发送用于请求数据传输的请求消息，其中，请求消息中携带有供二类次节点选择的用于并行数据传输的资源的第二资源范围信息；该主节点依据接收到的二类次节点发送的响应消息确定二类次节点的对应资源，其中，响应消息中携带有二类次节点依据第二资源范围信息选择的对应资源。其中，向二类次节点发送的请求消息为以下至少之一：单播请求发送RTS帧、单播预定帧、多播预定帧，其中，RTS帧中的保留指示位指示携带的第二资源范围信息，单播预定帧/多播预定帧的信息域指示用于二类次节点进行并行数据传输的第二资源范围信息；二类次节点反馈的响应消息为单播允许发送CTS帧或单播预定响应帧，其中，CTS帧中的保留指示位指示携带的二类次节点选择的对应资源，单播预定响应帧的信息域指示携带的二类次节点选择的对应资源。
优选地，依据对应资源对多个次节点进行并行数据传输处理时，可以采用不同的对应资源在同一时刻向多个次节点发送对应的数据，其中，向其中的二类次节点发送的每个数据中携带有用于调整对应次节点响应数据的响应信息的响应参数调整指示信息。需要说明的是，在采用不同的对应资源在同一时刻向多个次节点发送对应的数据之前，还需要获取对应于多个次节点的响应参数，其中，在该多个次节点均是二类次节点时，由主节点依据预定基准来确定响应参数调整指示信息；而在该多个次节点还包括不支持消息并行处理的一类次节点时，该响应参数调整指示信息可以依据上述一类次节点的响应参数为基准来确定。其中，该响应参数调整指示信息可以包括多种类型，例如，可以包括以下至少之一：功率调整信息、立即响应发送时间点调整信息、载波频率偏移预调整信息。
需要说明的是，在依据确定的资源协商方式确定分别对应于多个次节点的对应资源时，还可以包括：确定一类次节点所对应的资源包含主信道资源，其中，该主信道上的数据传输时间决定并行数据传输在辅信道上的传输时间。即主节点获取的传输机会的时间上限等于并行无线帧中占用主信道的数据所对应的接入类别的传输机会时间限制。
另外，上述对应资源可以为多种类型的资源，例如，可以包括以下至少之一：频域资源、码分资源、空域资源。其中，在该对应资源为频域资源的情况下，上述第一资源范围信息、第二资源范围信息包括以下至少之一：频段的起始位置和带宽信息；频段的临时主信道位置和带宽信息；频段的临时主信道位置；子信道列表信息。

下面结合附图对本发明优选实施方式进行说明。
在进行优选实施方式的说明之前，在用于并行数据传输的资源为频域资源的情况下，对频率范围指示信息指示内容分情况进行说明。
假设网络的运行带宽为160MHz，每20MHz为一个子信道，子信道号分别记为0,1,2,3,4,5,6,7。BSS的主信道为2号子信道。图10是根据本发明优选实施方式的信道划分示意图，如图10所示，该信道规划还定义了四个40MHz信道和2个80MHz信道，例如0和1可以组成一个40MHz信道，但是1和2就不可以组成一个40MHz信道。
频率范围指示信息可以为频段起始位置(或称信道起始位置)和带宽信息。例如，信道起始位置指示比特数为3比特，信道带宽指示比特数为2比特，当信道起始位置指示的值为“100”，信道带宽指示的值为“01”时，则代表频率范围为从4号子信道开始，包括4,5两个子信道的40MHz带宽。
频率范围指示信息可以为频段的临时主信道位置和带宽信息。例如，当指示的临时主信道为6号主信道，信道带宽为80MHz，则根据信道规划，频率范围为4,5,6,7四个子信道的80MHz带宽。
频率范围指示信息可以为频段的临时主信道位置，在无线帧的物理层帧头包含有该无线帧的发送带宽指示。例如，在并行传输建立过程中确定的某个STA的临时主信道位置为6号子信道，则该站点在并行传输时以6号子信道作为临时主信道进行载波检测，并根据检测结果和临时主信道上发送的物理帧头获知具体的数据带宽信息。
频率范围指示信息可以为子信道列表信息。例如，可以使用8个bit分别指示那些子信道可用，当指示为“01001111”时，代表1,4,5,6,7号子信道可供使用。
实施例一
AP与多个non-AP STA组成一个BSS。其中，BSS的运行带宽为40MHz，包括20MHz主信道和20MHz辅信道，但其中STA1为仅支持11a标准的legacy STA，支持的最大带宽为20MHz，STA2为HEW站点，支持OFDMA传输和40MHz带宽。所有站点默认的检测信道至少包含主信道。
图11是根据本发明优选实施例一的并行传输建立示意图，如图11所示，AP想要使用OFDMA技术并行传输数据给STA1和STA2，则AP竞争获取传输机会TXOP(transmission opportunity)，发起并行传输建立过程：
AP发送RTS帧给STA1，STA1收到后回复CTS帧；AP接下来再发送一个RTS帧给STA2，该RTS帧包含频段范围指示信息，该信息指示了接下来的OFDMA并行传输中可供STA2的数据使用的频段资源为辅信道，STA2回复CTS帧，该帧中包含频段范围指示信息以确认要使用辅信道。上述过程中AP和STA2使用传统RTS/CTS帧中的保留指示位携带频率范围指示信道，具体的使用RTS/CTS帧中的服务域(SERVICE field)中的保留比特。上述RTS/CTS帧使用传统帧格式，发送信道包含主信道，以便能够让所有站点都能够监听到RTS/CTS，且RTS/CTS中携带有持续时间指示信息，用于预约当前传输机会将要占用的时间，旁听站点听到该信息后将不会竞争信道，以便将传输机会进行保护，其中，上述传输机会的时间长度上限为发送的主信道上STA1数据的接入类别(Access Category，简称AC)对应的传输机会时间限制(TXOP limit)，例如，STA1的数据属于视频接入类(AC_VO)，则上述AP获取的传输机会时长上限就为AC_VO对应的TXOP limit。可以看出AP分别和STA1和STA2进行RTS/CTS交互，保护了并行传输所使用的两条链路。
上述过程完成后，STA1在主信道上等待接收数据，STA2则在辅信道上等待接收数据，AP使用OFDMA方式并行发送数据给STA1和STA2，其中主信道上的子载波承载STA1的数据，辅信道上的子载波承载STA2的数据，上述给STA1的数据帧要求立即应答帧ACK(Acknowledgment)/BA(Block Acknowledgment)，STA1在接收完数据后等待一个帧间间隔后回复ACK/BA；上述给STA2的数据帧要求应答帧ACK/BA，且数据帧中包含响应参数调整指示，具体的为立即响应发送时间点调整信息，指示了STA2在延迟时间T后回复应答帧ACK/BA，上述时间T包括了STA1传输ACK/BA的时间和合适的帧间间隔时间。
数据接收完成后，STA1在帧间间隔后立即回复ACK/BA，STA2按照响应参数调整指示的信息，延迟T时间回复ACK/BA。
实施例二
AP与多个non-AP STA组成一个BSS。其中，BSS的运行带宽为80MHz，包括20MHz主信道(假设为0号子信道)和3个20MHz辅信道(1,2,3号子信道)，但其中STA1为支持11n标准的legacy STA，支持的最大带宽为40MHz，STA2为HEW站点，支持OFDMA传输和80MHz带宽。所有站点默认的检测信道至少包含主信道。
图12是根据本发明优选实施例二的并行传输建立示意图，如图12所示，AP想要使用OFDMA技术并行传输数据给STA1和STA2，则AP竞争获取传输机会TXOP(transmission opportunity)，发起并行传输建立过程：
AP发送RTS帧给STA1，STA1收到后回复CTS帧，STA1始终在包括主信道的40MHz上进行收发；AP接下来再发送一个RTS帧给STA2，该RTS帧包含频段范围指示信息，该信息指示了接下来的OFDMA并行传输中可供STA2的数据使用的频段资源，为2,3辅信道，STA2回复CTS帧，该帧中包含频段范围指示信息以确认要使用的信道，为3号信道，即AP和STA2可以协商使用的频段。可以看出AP分别和STA1和STA2进行RTS/CTS交互，保护了并行传输所使用的两条链路。
上述过程完成后，STA1在主信道上等待接收数据，STA2则在3号辅信道上等待接收数据，AP使用OFDMA方式并行发送数据给STA1和STA2，其中主信道和1号辅信道上的子载波承载STA1的数据，3号辅信道上的子载波承载STA2的数据，上述给STA1的数据帧要求立即应答帧BA，STA1在接收完数据后等待一个帧间间隔后回复BA；上述给STA2的数据帧要求立即应答帧BA，STA2的BA与STA1的BA在不同子信道上并行发送，且STA2的数据帧中包含响应参数调整指示，具体的可以包括功率调整信息、立即响应发送时间点调整信息、载波频率偏移预调整信息，指示了STA2按照立即响应发送时间点调整信息调整自己的BA发送时间点；按照载波频率偏移预调整信息调整发送BA的载波频谱；按照功率调整信息调整发送BA的功率，使得STA2发送的BA与STA1发送的BA能够并行传输保证被AP能够正确接收。上述全部或部分响应参数调整指示可以位于数据帧的MAC帧头中，具体的可以使用MAC帧头的保留位，可以设置在MAC帧头中增加的信息域中；上述响应参数调整指示全部或部分也可以位于数据帧的物理层帧头中。
STA1在帧间间隔后在主信道和1号辅信道立即回复BA，STA2按照响应参数调整指示在3号信道上发送BA，即BA的发送频带和接收到的自己的数据的频带相同。
实施例三
AP与多个non-AP STA组成一个BSS。其中，BSS的运行带宽为160MHz，包括20MHz主信道(假设为0号子信道)和7个20MHz辅信道(1,2,3,4,5,6,7号子信道)，但其中STA1为支持11ac标准的legacy STA，支持的最大带宽为160MHz，STA2，STA3为HEW站点，支持OFDMA传输和160MHz带宽。AP想要使用OFDMA技术并行传输数据给STA1，STA2和STA3，则AP竞争获取传输机会TXOP(transmission opportunity)，发起并行传输建立过程：
AP在发送RTS帧给STA1，且指示与STA1的通信可以动态调整带宽，指示可供STA1使用带宽为160MHz，STA1收到后回复CTS帧，且指示选择40MHz带宽与AP进行通信，现有技术中只指示带宽值就可以确定信道，例如，上述40MHz带宽是包括主信道的40MHz带宽，即该实施例中的0,1两个子信道；AP接下来再发送一个RTS帧给STA2，该RTS帧包含频段范围指示信息，该信息指示了接下来的OFDMA并行传输中可供STA2的数据使用的频段资源，例如，可以使用实施例一种的信息指示方法，即除去STA1选择的信道所剩余的信道，为2,3,4,5,6,7辅信道，STA2回复CTS帧，该帧中包含频段范围指示信息以确认要使用的信道，为2,3号信道，即AP和STA2可以协商使用的频段；最后，AP接下来再发送RTS帧给STA3，该RTS帧包含频段范围指示信息，该信息指示了接下来的OFDMA并行传输中可供STA3的数据使用的频段资源，即除去STA1和STA2选择的信道所剩余的信道，为4,5,6,7辅信道，STA2回复CTS帧，该帧中包含频段范围指示信息以确认要使用的信道，为4,5,6,7号信道。可以看出AP分别和STA1、STA2和STA3进行RTS/CTS交互，保护了并行传输所使用的三条链路。
上述过程完成后，AP使用OFDMA方式并行发送数据，其中主信道和1号辅信道上的子载波承载STA1的数据，2，3号辅信道上的子载波承载STA2的数据，4，5，6,7号辅信道上的子载波承载STA3的数据。上述给STA1的数据帧要求立即应答帧BA，STA1在接收完数据后等待一个帧间间隔后回复BA；上述给STA2,3的数据帧要求后续块确认，即STA2和STA3接收到AP发送BAR帧(Block ACK request)后回复数据帧的确认帧BA。
并行数据帧发送完成后，STA1立即回复应答帧BA，AP收到STA1的应答后，发送BAR给STA2，STA2回复BA，然后AP发送BAR给STA3，STA3回复BA。
实施例四
AP与多个non-AP STA组成一个BSS。其中，BSS的运行带宽为160MHz，包括20MHz主信道(假设为0号子信道)和7个20MHz辅信道(1,2,3,4,5,6,7号子信道)，但其中STA1为支持11ac标准的legacy STA，支持的最大带宽为160MHz，STA2，STA3为HEW站点，支持OFDMA传输和160MHz带宽。
图13是根据本发明优选实施例四的并行传输建立示意图，如图13所示，AP可以使用并行传输请求帧和并行传输应答帧完成并行传输建立过程。上述并行传输请求帧和并行传输应答帧为新定义的帧格式，不能被一类站点所解析，这些帧的使用方法可以为：
若多用户并行传输的站点既有一类站点又有二类站点，则可以使用传统帧与一类站点进行传输链路建立，然后使用新定义的并行传输请求帧和其响应帧与二类站点进行传输链路建立，使用RTS/CTS与STA1通信，使用并存传输请求帧与STA2和STA3通信，具体的AP发送并行传输请求帧给STA2和STA3，该帧中分别携带有STA2和STA3的标识信息和频段范围指示信息，STA2和STA3按照顺序会议并行传输应答帧。
若多用户并行传输的站点都是二类站点，例如STA2和STA3，则AP发送并行传输请求帧给STA2和STA3，该帧中分别携带有STA2和STA3的标识信息和频段范围指示信息，STA2和STA3按照顺序会议并行传输应答帧。
实施例五
图14是根据本发明优选实施例五的并行传输建立示意图，如图14所示，AP可以使用并行传输请求帧和并行传输应答帧完成并行传输建立过程。上述并行传输请求帧和并行传输应答帧为新定义的帧格式，不能被一类站点所解析，这些帧的使用方法如下：
AP给STA2发送并行请求帧，并接收STA2的并行回应帧，同样的，AP与STA3也进行上述过程。上述并行请求帧和回应帧中包含有频段范围指示信息。
显然，本领域的技术人员应该明白，上述的本发明实施例的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
以上所述仅为本发明实施例的优选实施例而已，并不用于限制本发明实施例，对于本领域的技术人员来说，本发明实施例可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
如上所述，通过上述实施例及优选实施方式，不仅解决了相关技术中存在的由于WLAN自身的特点并不能建立有效并行传输链路，因而使得WLAN网络无法直接进行并行数据传输的问题，进而达到了不仅能够有效避免并行传输受到干扰，以及能够有效兼容网络新旧设备，有效提高网络效率的效果。
