Description

多链路连接的建立方法、装置、设备及介质 技术领域
本申请实施例涉及通信技术领域，特别涉及一种多链路连接的建立方法、装置、设备及介质。
背景技术
在IEEE(Institute of Electrical and Electronics Engineers，电气与电子工程师协会)802.11be中，定义了可以支持多链路(Multiple Links)的功能。按照IEEE 802.11中对通信两端的定义，站点(Station，STA)多链路设备(Multi-Link Device，MLD)和接入点(Access Point，AP)MLD之间建立了多条链路，STA MLD和AP MLD可以利用多链路的优势，在多个链路上进行数据收发，以达到高吞吐、低时延等优势。
STA MLD具有一个MLD MAC Address(多链路设备MAC地址)，STA MLD的每个链路有独立的Link MAC Address(链路MAC地址)。STA MLD和AP MLD在进行Multi-link Setup(多链路建立)时，AP MLD基于STA MLD的MLD MAC Address与STA MLD建立连接。
由于AP MLD基于STA MLD的MLD MAC Address来识别STA MLD，当不同的STA MLD在各自的某个Link上的Link/WM MAC Address(链路/无线媒介MAC地址)相同，AP MLD无法区分接收信息来自哪个STA MLD。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，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。
本申请实施例的技术方案可以应用于各种通信系统，例如：无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)或其他通信系统等。
请参考图1，其示出了本申请一个示例性实施例提供的无线局域网的框图，该无线局域网可以包括：站点(STA)MLD10和接入点(AP)MLD 20。
其中，站点MLD 10和接入点MLD 20之间存在多链路。
接入点MLD 20是一种部署在无线局域网中用以为站点MLD 10提供无线通信功能的设备。站点MLD10可以包括：用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、用户代理或用户装置。可选地，站点MLD 10还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digita1Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，本申请实施例对此并不限定。
在一些场景中，AP或称AP STA，即在某种意义上来说，AP也是一种STA。
在一些场景中，STA或称非AP STA(non-AP STA)。通信系统中的通信可以是AP与non-AP STA之间的通信，也可以是non-AP STA与non-AP STA之间的通信，或者STA和peer STA之间的通信，其中，peer STA可以指与STA对端通信的设备，例如，peer STA可能为AP，也可能为non-AP STA。
应理解，STA在通信系统中的角色不是绝对的，例如，在一些场景中，手机连接路由的时候，手机是non-AP STA，手机作为其他手机的热点的情况下，手机充当了AP的角色。
在本申请实施例中，站点MLD 10和接入点MLD 20均支持IEEE 802.11标准。
在一些实施例中，non-AP STA可以支持802.11be制式。non-AP STA也可以支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的无线局域网(wireless local area networks，WLAN)制式。
在一些实施例中，AP可以为支持802.11be制式的设备。AP也可以为支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的WLAN制式的设备。
在本申请实施例中，STA可以是支持WLAN/WiFi技术的手机(Mobile Phone)、平板电脑(Pad)、电脑、虚拟现实(Virtual Reality，VR)设备、增强现实(Augmented Reality，AR)设备、工业控制(industrial control)中的无线设备、机顶盒、无人驾驶(self driving)中的无线设备、车载通信设备、远程医疗(remote medical)中的无线设备、智能电网(smart grid)中的无线设备、运输安全(transportation safety)中的无线设备、智慧城市(smart city)中的无线设备或智慧家庭(smart home)中的无线设备、无线通信芯片/ASIC/SOC/等。
AP和non-AP STA可以是应用于车联网中的设备，物联网(Internet Of Things，IoT)中的物联网节点、传感器等，智慧家居中的智能摄像头，智能遥控器，智能水表电表等，以及智慧城市中的传感器等。
在介绍本申请技术方案之前，先对本申请涉及的一些技术知识进行介绍说明。
在IEEE 802.11be中，定义了可以支持IEEE 802.11多链路的功能。按IEEE 802.11中对于通信两端的定义，一个是站点MLD，一个是接入点MLD。相互建立了多链路的站点MLD和接入点MLD可以利用多链路的优势，在多个链路上进行数据收发，以达到高吞吐/低时延等优势。
在传统的支持IEEE 802.11的单链路设备中，每个单链路设备都有一个MAC(Medium Access Control，媒体接入控制)地址(address)，这个单链路设备可以用这个MAC地址来识别。在IEEE 802.11be定义的MLD中，因为在MLD中会有多个链路，每个链路上都有独立的MAC地址，同时一个MLD还有一个MLD MAC address(多链路设备MAC地址/设备MAC地址)。图2为IEEE 802.11be中定义的MLD的参考模型。图2中显示了两个MLD(STA MLD和AP MLD/Non-AP MLD)之间有两个链路Link1/Link2，且每个MLD中在MLD Lower MAC layer(MAC层以下的层/低层)中，在每个链路上都有独立的Link MAC address(链路MAC地址)，或称为WM(Wireless Medium，无线媒介)MAC Address，AP MLD在Link1的链路MAC地址为w，AP MLD在Link2的链路MAC地址为x，STA MLD在Link1的链路MAC地址为y，STA MLD在Link2的链路MAC地址为z；同时在MLD Upper MAC layer(MAC层以上的层/高层)中有一个MLD MAC address，AP MLD的多链路设备MAC地址(或称“设备MAC地址”)为M，STA MLD的设备MAC地址为P。
在MLD中，划分出MLD Lower MAC layer和MLD Upper MAC layer，是因为在MLD中有些功能是每个Link(链路)上独立的，即Link Level functionality(链路级功能)；有些功能是所有Link上统一共同拥有的，即MLD Level functionality(多链路设备级功能)。这样Link level functionality可以通过Link MAC address来作识别(identification)，MLD level functionality可以通过MLD MAC address来作识别(identification)。
在IEEE 802.11be中，用MLD MAC Address来识别出不同的MLD，但MLD在每个链路上发送的802.11帧中，是使用该链路对应Link/WM MAC address(链路/无线媒介媒体接入控制地址)作识别。如图3所示，为一个有三个链路的STA MLD，每个链路STA1/STA2/STA3都有各自的Link/WM MAC Address，而整个STA MLD是使用MLD MAC address来作识别的。
在IEEE 802.11be中，STA MLD和AP MLD建立多链路(multiple links)的连接时，即STA MLD和 AP MLD的Multi-link Setup(多链路建立)时，这两个MLD间的连接状态相关的功能，比如鉴权(Authentication)，连接(association)，和重连接(reassociation)为MLD level functionality，所以是通过MLD MAC address来识别的。在STA MLD和AP MLD的Multi-link Setup(多链路建立)时，是允许STA MLD和AP MLD只在任一个链路上进行连接过程，通过在这个链路上的连接过程中相互交互的信息，来协商出其他链路上的连接参数，并将其他链路上的链路连接也建立好。例如，如图4所示，STA MLD和AP MLD间在Link1上进行Multi-Link Setup过程。STA MLD先发送Association Request(连接请求帧)，连接请求帧会携带STA MLD的MLD MAC Address，以及STA MLD想要在哪些链路上与AP MLD建立连接，以及每个链路上STA MLD所对应的STA1/2/3的Link/WM MAC Address。在AP MLD接受了STA MLD多链路连接请求后，会在回复给STA MLD的Association Response(连接响应帧)中，携带对应的AP MLD的MLD MAC Address，以及每个链路上AP MLD所对应的AP1/2/3的Link/WM MAC Address。
如图5所示，为STAMLD所发送的Associate Request帧中所携带的部分信息，其中的MLD Level Information(多链路设备级信息)相关字段中会携带STAMLD的MLD MAC address；在Link Level Information(链路级信息)相关字段中会携带STAMLD预期建立连接的每个Link上的相关信息，包括了对应的Link的Link ID(链路编号)以及每个Link上的STAMLD所对应的Link MAC address，其中，address简写为“ADDR”。
如图6所示，为APMLD所发送的Associate Response帧中所携带的部分信息，其中的MLD Level Information相关字段中会携带APMLD的MLD MAC address，同时包含了APMLD是否接受了STAMLD的多链路连接请求Status Code(状态码)；在Link Level Information相关字段中会携带STAMLD预期建立连接的每个Link上的相关信息，包括了对应的Link的Link ID以及每个Link上的APMLD所对应的Link MAC address，同时包含了APMLD是否在每个Link上接受了STAMLD对应连接请求的信息Status Code。
在当前IEEE 802.11be中，由于AP MLD是按某个STA MLD的MLD MAC Address来维护一个连接状态(Association State)，但未检测STA MLD中对应的每个链路上的Link/WM MAC Address。这就导致，会出现如下情况：有两个STA MLD，STAMLD0和STAMLD1，所具有的MLD MAC Address不同，但STAMLD0和STAMLD1中在各自的某个Link上的Link/WM MAC Address相同。
如图7所示，STAMDL0的MLD MAC Address是X，在Link0上的Link MAC Address是A，在Link1上的Link MAC Address是B；STAMLD1的MLD MAC Address是Y，在Link0上的Link MAC Address是C，在Link1上的Link MAC Address也是B。当STAMLD0先在Link0上向APMLD进行多链路连接Multi-Link Setup时，STA MLD 0向AP MLD发送连接请求帧，连接请求帧中携带了STA MLD 0的MLD MAC Address＝X；APMLD检测到当前没有记录有和MLDMACADDR＝X已有的连接状态，所以APMLD可以接受连接请求，与STAMLD0在Link0/Link1上建立多链路，且在APMLD侧，将这个连接以MLDMACADDR＝X作为识别，向STA MLD 0发送连接响应帧，连接响应帧标注AP MLD和STA MLD 0成功建立多链路连接。当STAMLD1在Link0上向APMLD进行多链路连接时，STA MLD 1向AP MLD发送连接请求帧，连接请求帧中携带了STA MLD 1的MLD MAC Address＝Y；APMLD检测到当前没有记录有和MLDMACADDR＝Y已有的连接状态，所以APMLD可以接受连接请求，与STAMLD 1在Link0/Link1上建立多链路，且在APMLD侧，会将这个连接以MLDMACADDR＝Y作为识别，向STA MLD 1发送连接响应帧，连接响应帧标注AP MLD和STA MLD 1成功建立多链路连接。
如图7所示，STA MLD 0和STA MLD 1都与AP MLD建立连接后，由于STAMLD0和STAMLD1在Link1上的对应的Link MAC address是相同的，当APMLD在Link1上收到一个802.11帧时，且该802.11帧携带的是LINKMACADDR＝B，此时APMLD无法区分该802.11帧是来自于STAMLD0还是STAMLD1；同样，当APMLD发出一个携带LINKMACADDR＝B的802.11帧时，STAMLD0/STAMLD1都会认为该802.11帧是发给自己的。
针对上述问题，本申请实施例提供了一种方法，在建立多链路连接时，即考虑到不同站点的链路MAC地址可能相同的问题，基于站点多链路设备所发送的连接请求帧中携带的链路MAC地址来发送连接响应帧，根据连接请求帧中的链路MAC地址与已连接的站点的链路MAC地址的相同情况，来确定是否接受连接请求，进而生成连接请求帧并发送。
如图8所示，STA MDL 0的MLD MAC Address是X，在Link0上的Link MAC Address是A，在Link1上的Link MAC Address是B；STA MLD 1的MLD MAC Address是Y，在Link0上的Link MAC Address是C，在Link1上的Link MAC Address也是B。在STA MLD 0与AP MLD建立连接后，STA MLD 1向AP MLD发送连接请求，连接请求中携带了STA MLD 1的两个链路MAC地址：Link MAC Address＝C、Link MAC Address＝B；AP MLD会发现Link MAC Address＝B与已连接的STA MDL 0的Link1的Link MAC Address相同，且已连接的站点中不存在与Link MAC Address＝C相同的Link MAC Address，则基于这种情况，AP MLD可以生成连接成功的连接响应帧，向STA MLD 1指示在Link0上连接成功，在Link1上连接 失败；或，AP MLD可以生成连接失败的连接响应帧。
请参考图9，其示出了本申请一个实施例提供的多链路连接的建立方法的流程图。该方法可应用于图1所示的通信系统中的AP MLD中。该方法可以包括如下步骤：
步骤901：接收至少一个站点多链路设备发送的连接请求帧，每个连接请求帧分别包括一组链路媒体接入控制MAC地址，一组链路MAC地址包括站点多链路设备请求建立连接的链路的链路MAC地址。
示例性的，接入点设备接收至少一个站点多链路设备发送的至少一个连接请求帧。
在接入点设备接收到一个站点多链路设备发送的一个连接请求帧的情况下，接入点设备基于该连接请求帧中的一组链路MAC地址，向该站点多链路设备发送连接响应帧。
在接入点设备接收到至少两个站点多链路设备发送的至少两个连接请求帧的情况下，接入点设备基于该至少两个连接请求帧中的至少两组链路MAC地址，向每个站点多链路设备发送连接响应帧。
示例性的，接入点多链路设备可以同时或不同时接收至少两个站点多链路设备发送的连接请求帧。即，该接入点多链路设备接收到该至少两个连接请求帧的时间差小于时间阈值。示例性的，接入点多链路设备同时对该至少两个连接请求帧进行处理，分别确定所需要发送的至少两个连接响应帧。

示例性的，接入点多链路设备向站点多链路设备广播接入点多链路设备的链路标识；站点多链路设备在需要建立多链路连接时，在连接请求帧中携带想要建立连接的链路标识，以及在该链路上站点多链路设备的链路MAC地址。

示例性的，连接响应帧中携带了连接状态码，连接状态码用于标识连接结果，例如，连接状态码包括连接失败信息或连接成功信息。

链路级连接状态码用于标识站点多链路设备和接入点多链路设备是否在某个链路上成功建立连接。
示例性的，在连接成功的情况下，如图6所示，连接响应帧包括：设备级连接状态码601、多链路设备级信息(接入点多链路设备级信息)和链路级信息(接入点链路级信息)。在连接失败的情况下，连接响应帧包括：设备级连接状态码和多链路设备级信息；或，连接响应帧包括：设备级连接状态码、多链路设备级信息和链路级信息。即，在连接失败的情况下，连接响应帧中可以携带连接请求帧中所请求的每个链路对应的链路级信息；连接响应帧中也可以不携带连接请求帧中所请求的每个链路对应的链路级信息。
在连接成功的情况下，接入点多链路设备向站点多链路设备指示每个链路上的连接状态。在连接失败的情况下，接入点多链路设备可以向站点多链路设备指示每个链路上是否连接成功，或，接入点多链路设备不向站点多链路设备指示每个链路上是否连接成功。

例如，如图5所示，连接请求帧中的链路级信息包括：Link0的Link ID、STA MLD在Link0上的链路MAC地址、Link1的Link ID、STA MLD在Link1上的链路MAC地址。则如图6所示，连接响应帧中的链路级信息包括：Link0的Link ID、AP MLD在Link0上的链路MAC地址、Link0的链路级连接状态码、Link1的Link ID、AP MLD在Link1上的链路MAC地址、Link1的链路级连接状态码。
综上所述，本实施例提供的方法，在建立多链路连接时，接入点多链路设备基于站点多链路设备在连接请求帧中携带的链路MAC地址来发送连接响应帧。针对不同站点多链路设备可能存在相同的链路MAC地址的问题，接入点多链路设备可以根据连接请求帧中的链路MAC地址来辨别是否存在其他站点的链路MAC地址与之相同，进而确定是否接受该连接请求，向站点多链路设备发送连接响应帧。
请参考图10，其示出了本申请一个实施例提供的多链路连接的建立方法的流程图。该方法可应用于图1所示的通信系统中的STA MLD中，该STA MLD可以为第一站点多链路设备。该方法可以包括如下步骤：

综上所述，本实施例提供的方法，在建立多链路连接时，接入点多链路设备基于站点多链路设备在连接请求帧中携带的链路MAC地址来发送连接响应帧。针对不同站点多链路设备可能存在相同的链路MAC地址的问题，接入点多链路设备可以根据连接请求帧中的链路MAC地址来辨别是否存在已连接的站点的链路MAC地址与之相同，进而确定是否接受该连接请求，向站点多链路设备发送连接响应帧。
示例性的，下面针对如下两种情况进行分别举例说明：
(一)接入点多链路设备基于一个站点多链路设备发送的连接请求帧，确定该站点多链路设备的连接响应帧。
(二)接入点多链路设备基于多个站点多链路设备发送的连接请求帧，确定一个站点多链路设备的连接响应帧。

若STAMLD在全部链路上所对应的Link MAC address，与APMLD已经建立连接的另外一个或多个STAMLD或STA所对应的Link MAC address相同，则APMLD拒绝STAMLD的多链路连接请求。
通过在建立多链路连接时，检查站点多链路设备所请求的链路的链路MAC地址是否与已连接的站点的链路MAC地址相同，针对其是否相同的情况发送连接响应帧，防止与接入点多链路设备建立连接的站点对应有相同的链路MAC地址，避免由于链路MAC地址相同导致的帧交互失败的情况。

示例性的，本实施例中6种情况的说明，可以参照图11所示的示例性实施例中6种情况的说明，将图11所示实施例6种情况中的“第二组链路MAC地址”替换为“第四组链路MAC地址”后，同样适用于对本实施例中6种情况的解释。因此，本实施例在此不再赘述。
综上所述，本实施例提供的方法，STA MLD和AP MLD在进行Multi-Link Setup过程中，AP MLD需要对STA MLD所请求的所有链路上对应的Link MAC Address进行检测，判断是否与AP MLD已经建立连接的一个或多个STA MLD或STA所对应的Link MAC address相同，或，是否与其他请求建立连接的一个或多个STA MLD或STA所对应的Link MAC address相同。
若STA MLD在发送Association Request帧的链路上所对应的Link MAC address，与AP MLD中已经建立连接的另一个STA MLD或STA所对应的Link MAC address相同，或，与其他请求建立连接的另一个STA MLD或STA所对应的Link MAC address相同，则AP MLD拒绝STA MLD的多链路连接请求，或者AP MLD有条件地接受STA MLD在部分链路上的连接请求。
若STA MLD在除发送Association Request帧的链路之外的其余链路上所对应的Link MAC address，与AP MLD已经建立连接的另外一个或多个STA MLD或STA所对应的Link MAC address相同，或，与其他请求建立连接的另一个STA MLD或STA所对应的Link MAC address相同，则AP MLD拒绝STA MLD的多链路连接请求，或者AP MLD有条件地接受STA MLD在部分链路上的连接请求。
若STA MLD在全部链路上所对应的Link MAC address，与AP MLD已经建立连接的另外一个或多个STA MLD或STA所对应的Link MAC address相同，或，与其他请求建立连接的另一个STA MLD或STA所对应的Link MAC address相同，则AP MLD拒绝STA MLD的多链路连接请求。
通过在建立多链路连接时，检查站点多链路设备所请求的链路的链路MAC地址是否与已连接的站点的链路MAC地址相同、是否与其他请求建立连接的站点的链路MAC地址相同，针对其是否相同的情况发送连接响应帧，防止与接入点多链路设备建立连接的站点对应有相同的链路MAC地址，避免由于链路MAC地址相同导致的帧交互失败的情况。
