Description

多链路并发连接方法、装置及设备
本申请要求于2022年11月26日提交国家知识产权局、申请号为202211495295.5、申请名称为“多链路并发连接方法、装置及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及多链路并发连接方法、装置及设备。
背景技术
电气和电子工程师协会(institute of electrical and electronics engineers，IEEE)标准802.11中，多链路设备(multi-link device，MLD)是指支持多链路操作(multi-link operation，MLO)功能的逻辑实体，能够实现负载平衡、多频段聚合和同步下行链路/上行链路传输，达到多频段高效操作的目的。
目前，在漫游场景或多网络并发连接场景中，非接入点多链路设备(non-access point multi-link device，non-AP MLD)需要先断开与原接入点多链路设备(access point multi-link device，AP MLD)的连接，再与新AP MLD建立连接。在non-AP MLD与新AP MLD的连接建立完成之后，non-AP MLD和新AP MLD之间才能进行业务传输。前述过程可简称为non-AP MLD与多个AP MLD的先断后连。
可见，在断开non-AP MLD和原AP MLD的连接之前，non-AP MLD将无法连接到新AP MLD，导致业务传输发生中断，增加了业务传输的中断时间，无法满足漫游场景或多网络并发连接场景的低时延需求。
发明内容
本申请提供一种多链路并发连接方法、装置及设备，能够实现低时延或零中断实现漫游或多网络并发连接。
第一方面，本申请提供一种多链路并发连接方法，包括：
第一设备通过第一链路集合与第二设备建立多链路连接，第一链路集合包括第一链路和第二链路；
第一设备通过第二链路集合与第三设备建立多链路连接，第二链路集合包括第三链路和第四链路；其中，第三链路和第一链路的工作频点相同，或者，第三链路、第一链路和第二链路的工作频点皆不同。
通过第一方面提供的多链路并发连接方法，第一设备通过多个媒体接入控制层服务接入点，在不断开与第二设备的多链路连接的情况下，可建立与第三设备的多链路连接，实现了第一设备与第二设备和第三设备的多链路并发连接。这样，能够支持先连后断的漫游，减少了业务传输的中断时间，实现了低时延或零中断的漫游场景，解决了MLO功能与低时延或零中断的漫游功能不兼容的问题，也能够支持多个设备的多网络并发连接，实现了低时延或零中断的多网络并发连接场景，解决了MLO功能与低时延或零中断的多网络并发连接功能不兼容的问题，从而支持无缝漫游或并发多网络连接等功能，同时具有吞吐量高且网络灵活性好等优势，可实现多频段和多链路的高效资源管理、信道接入、协同传输等。
在一种可能的设计中，第一链路集合中的链路的数据是由第一设备的第一媒体接入控制层服务接入点传输的，第二链路集合中的链路的数据是由第一设备的第二媒体接入控制层服务接入点传输的，第一设备的第一媒体接入控制层服务接入点与第一设备的第二媒体接入控制层服务接入点不同。
由此，第一设备通过两个媒体接入控制层服务接入点，可分别向第二设备和第三设备提供两个媒体接入控制层(media access control，MAC)接口，使得第一设备与第二设备和第三设备业务传输时不会发生冲突，为实现第一设备的多链路连接提供了可能。

由此，借助多个媒体接入控制层服务接入点和利用与第一链路集合中的链路皆不同的工作频点，第一设备可实现多链路并发连接功能。
这样，第一设备通过第一链路集合可与第二设备进行业务传输，同时，第一设备通过第二链路集合可与第三设备进行业务传输，使得第一设备实现了低时延或零中断的多网络并发连接场景。

在一种可能的设计中，该方法还包括：
第一设备断开第一链路集合；
第一设备在第三链路和/或第四链路上传输第一设备与第三设备之间的业务。
由此，第一设备可从多链路连接第二设备和第三设备切换到多链路连接第三设备，使得第一设备实现了低时延或零中断的漫游场景。

首先，下面对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1、多链路(multilink，ML)
为了达到极高吞吐率(extremely high throughput，EHT)，IEEE 802.11be将ML作为关键技术之一。其核心思想是支持下一代IEEE 802.11标准的无线局域网(wireless local area network，WLAN)设备拥有在多频段(multi-band)发送和接收的能力，从而可以使用更大的带宽进行业务传输，进而显著提升吞吐率。其中，在一个频段上进行接入和业务传输的空间路径可以称为一条链路(Link)，从而多个频段上的接入和业务传输便成为ML。另外，多链路对于减小时延和提高鲁棒性都很有帮助。
示例性的，上述多频段包括但不限于：2.4吉赫兹(GHz)无线保真(wireless fidelity，Wi-Fi)频段、5GHz Wi-Fi频段、6GHz Wi-Fi频段以及高频60GHz频段中的全部或部分。
其中，不同链路的接入频点不同。此外，不同链路的接入频段可以不同。或者，不同链路的接入频段可以相同，也即不同链路可以位于同一频段上。该情况下，不同链路可以接入相同频段的不同信道，从而在不同信道上进行业务传输。
2、MLD，也称多频段设备(multi-band device)
MLD是指同时支持多条链路的WLAN设备。即MLD具有在多个频段上的发送和接收的能力，相比于仅支持单条链路传输的设备来说，MLD具有更高的传输效率和更高的吞吐量。
其中，MLD也可以称为多频段设备(multi-band device)，或者MLD也可以有其他名称，本申请对此不做具体限定。
MLD包括多个隶属站点(affiliated station，affiliated STA)。
其中，隶属站点是逻辑上的站点。隶属站点可以为接入点站点(access point station，AP STA)或非接入点站点(non-access point station，non-AP STA)。
为简化描述，本申请将隶属站点为AP STA的多链路设备称为AP MLD。AP STA称为隶属AP。这样，AP MLD中包括多个隶属AP，隶属AP是逻辑上的AP。
隶属站点为non-AP STA的MLD称为non-AP MLD。non-AP STA称为隶属STA。这样，non-AP MLD中包括多个隶属STA，隶属STA是逻辑上的STA。
其中，AP MLD也可称为多链路AP或多链路AP设备或其他名称，本申请对此不做具体限定。non-AP MLD也可称为多链路STA或多链路STA设备或STA MLD或其他名称，本申请对此不做具体限定。
目前，在公共频段或设备均支持的信道上，支持MLO功能的non-AP MLD和AP MLD可互相发现、同步、(去)身份验证、(重新)关联、取消关联和管理资源，能够实现高吞吐、低时延、业务配置灵活的多频段、和多链路并发连接。
其中，上述的多链路并发连接指的是至少一个non-AP MLD和多个AP MLD可实现多条链路的建立，并根据链路指标或者用户配置，使得至少一个non-AP MLD和多个AP MLD中的一个或多个AP MLD能够通过多条链路进行业务传输，实现漫游场景或多网络并发连接场景。其中，链路指标可包括：信道质量或吞吐量等指标。
在non-AP MLD和AP MLD的任意一条链路上，通过交互关联请求帧(association request frame)和关联响应帧(association response frame)，或者，重新关联请求帧(re association request frame)和重新关联响应帧(re association response frame)通知链路能力等相关参数，可实现non-AP MLD和AP MLD的多链路建立。
相关技术中，MLD仅具有用于接入逻辑链路控制(logical link control，LLC)层的唯一的媒体接入控制层(media access control layer，MAC层)的服务接入点(service access port，SAP)，可为MLD提供1个MAC接口，对应唯一的MAC地址(还可称为物理地址或硬件地址)，即提供1个MAC数据服务。
应理解，802.11系列标准关注于MLD的物理层(physical layer，PHY)和MAC层部分。
MLD中的每个隶属站点(如隶属STA和隶属AP)中都有一个站点管理实体(station management entity，SME)。
其中，SME是一个独立于层的实体，它位于单独的管理平面中或位于侧面(off to the side)，SME的某些功能可参见在802.11系列标准中的定义。
SME通过与MAC子层管理实体(MAC sublayer management entity，MLME)进行交互，可控制和管理MAC层，通过与PHY子层管理实体(PHY sublayer management entity，PLME)进行交互，可控制和管理PHY层。
其中，MAC层包含MLD upper MAC sublayer和MLD lower MAC sublayer，其中，MLD upper MAC sublayer功能包括：1、鉴权和连接；2、生成安全秘钥；3、帧序列号分配；4、帧加密和解密；5、数据包记录和重排序；6、选择发送数据的L-MAC模块和与L-MAC的信息交互。MLD lower MAC sublayer功能包括：1、链路级别的管理信息交互和指示，例如信标(beacon)消息；2、链路级别的控制信息交互和指示，例如发送请求(request to send，RTS)帧，发送清除(clear to send，CTS)帧。
可见，non-AP MLD也具有唯一的SAP，对应唯一的MAC地址，与AP MLD关联的每个隶属AP都具有各自不同的MAC地址。AP MLD也具有唯一的SAP，对应唯一的MAC地址，与non-AP MLD关联的每个隶属STA都具有各自不同的MAC地址。
基于此，在漫游场景或多网络并发连接场景中，由于MLD仅提供一个SAP，non-AP MLD便需要先断开与原AP MLD的连接，再与新AP MLD建立连接。在non-AP MLD与新AP MLD的连接建立完成之后，non-AP MLD和新AP MLD之间才能进行业务传输。
否则，仅利用唯一的SAP提供的唯一MAC接口，即使建立了non-AP MLD和原AP MLD的多条链路，non-AP MLD和原AP MLD之间的业务传输，与non-AP MLD和新AP MLD之间的业务传输也会发生冲突。
由此，在断开non-AP MLD和原AP MLD的连接之前，non-AP MLD中的隶属STA将无法连接到新AP MLD或新AP MLD中的隶属AP，造成业务传输中断，无法实现低时延的漫游或多网络并发连接。
为了解决上述痛点，本申请提供一种多链路并发连接方法、装置及设备，借助增加SAP的数量，通过多个SAP提供的多个MAC接口，在保持与原设备的多链路连接的情况下，支持与新设备的多链路连接，从而，能够支持先连后断的漫游或多设备的多网络并发连接，能够减少业务传输的中断时间，实现低时延或零中断的漫游场景或多网络并发连接场景，有利于提高用户体验和通信效率。
本申请的多链路并发连接方法可以应用于无线通信系统的漫游场景，如至少一个non-AP  MLD在至少两个AP MLD之间漫游的场景中，还可以应用于无线通信系统的多网络并发连接场景，如至少一个non-AP MLD多网络并发连接至少两个AP MLD的场景中，例如本地网和互联网，或者受限网络和互联网等。
其中，无线通信系统可以包括但限于：WLAN或蜂窝网，该方法可以由无线通信系统中的通信设备，或者通信设备中的处理器、芯片或芯片系统来实现，该通信设备可以是一种支持多条链路并行进行业务传输的通信设备，如MLD。比如，在WLAN中，MLD可以遵循802.11系列标准实现无线通信，802.11系列标准包括：802.11be、802.11ax、802.11a/b/g/n/ac、或下一代标准等。
当然，本申请还可以适用于其他可能的无线通信系统，例如，窄带物联网系统(narrow band-Internet of things，NB-IoT)、长期演进(long term evolution，LTE)系统、第五代(the 5th generation，5G)通信系统、第六代(the 6th generation，6G)通信系统等5G之后演进的通信系统。
应理解，上述描述仅为无线通信系统的举例说明，适用本申请的无线通信系统不限于此，在此不做一一说明。

其中，第一设备10可为non-AP MLD，或者non-AP MLD中的处理器、芯片或芯片系统等。第二设备20或第三设备30可为AP MLD，或者AP MLD中的处理器、芯片或芯片系统等。

其中，不同的SAP可为第一设备10提供不同的MAC接口，对应不同的MAC地址，即提供多个MAC数据服务。
为了简化描述，图1中，以第一设备10中包括不同的SAP1和SAP2为例进行示意。
第一设备10利用SAP1，可与第二设备20建立多条链路1，并可通过多条链路1与第二设备20进行业务传输。
换句话说，第一设备10和第二设备20之间的多链路连接和业务传输，实际上是第一设备10中的多个隶属STA分别通过多条链路1与第二设备20中的多个隶属AP之间的多链路连接和业务传输。
多条链路1中，每条链路1对应于第一设备10中的一个隶属STA和第二设备20中的一个隶属AP。不同的链路1对应的第一设备10中的隶属STA和第二设备20中的隶属AP皆不同。每条链路1的数据皆经过SAP1所提供的MAC接口。每条链路1的工作频点不同。每条链路1的工作频段可相同或不同。

多条链路2中，每条链路2对应于第一设备10中的一个隶属STA和第三设备30中的一个隶 属AP。不同的链路2对应的第一设备10中的隶属STA和第三设备30中的隶属AP皆不同。每条链路2的数据皆经过SAP2所提供的MAC接口。每条链路2的工作频点不同。每条链路2的工作频段可相同或不同。
其中，本申请对多条链路2的链路数量、每条链路2的工作频段、和每条链路2的工作频段等参数不做限定。
另外，多条链路1和多条链路2的链路数量、工作频点、工作频段和对应的第一设备10中的隶属STA等参数可相同或不同，只需满足多条链路1的数据和多条链路2的数据分别经过第一设备10中的不同的SAP所提供的MAC接口即可。
为了简化描述，图1中，以多条链路2包括两条链路Link3和Link4进行举例示意。
对于Link3而言，可以是第一设备10中的与Link3对应的隶属STA，经过SAP2所提供的MAC接口，和第三设备30中的与Link3对应的隶属AP之间的多链路连接和业务传输。

应理解，除SAP1和SAP2之外，第一设备10中还可包括其他SAP。从而，第一设备10还可与如其他non-AP MLD、其他AP MLD、其他类型的设备等进行多链路连接和业务传输。
其中，本申请涉及的non-AP MLD可以为无线通讯芯片、无线传感器或无线通信终端。例如支持WiFi通讯功能的用户终端(user terminal)、用户装置、接入装置、订户站(subscriber station)、订户单元(subscriber unit)、移动站(mobile station)、用户代理(user agent)、用户装备等，在此不作限定。其中，用户终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、物联网(internet of things，IoT)设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(user equipment，UE)、移动台(mobile station，MS)、终端(terminal)、终端设备(terminal equipment)、便携式通信设备、手持机、便携式计算设备、娱乐设备、游戏设备或系统，全球定位系统设备或被配置为经由无线介质进行网络通信的任何其他合适的设备等。此外，non-AP MLD可以支持802.11be制式或者802.11be的下一代WLAN制式。non-AP MLD也可以支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。

基于上述实施例的描述，在执行S102中的第一设备通过第二链路集合与第三设备建立多链路连接之前，第一设备可根据链路指标或者用户配置，确定是否启动多链路并发连接功能。
作为一种可能的实现，在第一设备发生移动时，第一设备可能移动至第二设备的信号覆盖区域的边缘，进入到第三设备的信号覆盖区域，导致第一链路集合中的链路的信道质量下降。可见，第一设备需要从多链路连接第二设备和第三设备切换到多链路连接第三设备。
从而，在监测到第一链路集合中的一条或多条链路的信道质量下降时，第一设备可确定启动多链路并发连接功能。
在一条链路的接收信号强度(received signal strength indicator，RSSI)小于第一阈值时，表示该条链路的信道质量下降。和/或，在一条链路的吞吐量小于第二阈值时，表示该条链路的信道质量下降。
其中，本申请对第一阈值和第二阈值的具体数值不做限定。第一阈值或第二阈值可根据业务需求和网络情况等参数进行设置。
作为一种可能的实现，第一设备根据用户需求，可确定第一设备与第二设备和第三设备需要多网络并发连接。
从而，在接收到用于指示启用多链路并发连接功能的用户指令时，第一设备可确定启动多链路并发连接功能。
其中，用户指令可为用户在第一设备或者与第一设备通信连接的其他设备中的硬件按键上进行触发所产生的指令，也可为在第一设备或者与第一设备通信连接的其他设备中的软件控件上进行触发所产生的指令，本申请对此不做限定。
另外，第一设备在启动多链路并发连接功能时，可显示一图标，该图标用于指示已启动多链路并发连接功能。其中，本申请对该图标的如形状、大小、颜色、位置、图案等参数不做限定。
基于上述实施例的描述，考虑到第一设备中的隶属STA的数量大于等于2个，第一链路集合和第二链路集合中的链路对应的第一设备中的隶属STA可能相同或不同。基于此，第一设备可采用多种实现方式，与第二设备和第三设备实现多链路并发连接，从而能够支持先连后断的漫游或多设备的多网络并发连接。
下面，在图3-图5实施例的基础上，结合图6-图9，详细介绍第一设备分别与第二设备和第 三设备实现多链路并发连接的多种实现方式。

在第三链路和第一链路的工作频点相同，第四链路和第二链路的工作频点相同时，第三链路和第一链路上不可同时进行业务传输，第四链路和第二链路不可同时进行业务传输，否则皆会造成业务传输的冲突。
作为一种可能的实现方式，第一设备与第二设备可禁用第一链路，启用第二链路。并且，第一设备与第三设备可启用第三链路，禁用第四链路。
作为一种可能的实现方式，第一设备与第二设备可启用第一链路，禁用第二链路。并且，第一设备与第三设备可禁用第三链路，启用第四链路。
其中，本申请提及的禁用任意一条链路可理解为禁用该链路的工作频点对应的信道，即该链路对应的隶属STA和隶属AP仍连接(即未断开)，但该链路对应的隶属STA和隶属AP无法在该链路或该信道上传输业务。
其中，本申请提及的启用任意一条链路可理解为启用该链路的工作频点对应的信道，即该链路对应的隶属STA和隶属AP能够在该链路或该信道上传输业务。
应理解，除上述方式之外，还可第三链路和第二链路的工作频点相同，第四链路和第一链路的工作频点相同，即禁用第一链路，启用第二链路，且禁用第三链路，启用第四链路，或者，启用第一链路，禁用第二链路，且启用第三链路，禁用第四链路。
另外，通常第一设备可禁用第一链路集合中的信道质量下降的链路。在禁用第一链路时，表示第一链路的信道质量下降。在禁用第二链路时，表示第二链路的信道质量下降。
其中，上述的实现方式的工作原理相同或类似。为了便于解释，以禁用第一链路，启用第二链路，且启用第三链路，禁用第四链路进行举例说明。
第一设备中的与第一链路对应的隶属STA与第二设备中的与第一链路对应的隶属AP可停止传输第一设备与第二设备之间的全部业务类型的业务，从而使得第一设备中的隶属STA可确定能够在第一链路的工作频点对应的信道上与第三设备中的隶属AP传输业务，为第一设备与第三设备之间的业务传输提供可能。
其中，第一设备中的隶属STA可为第一设备中的与第一链路对应的隶属STA，也可为第一设备中的能够在第一链路的工作频点对应的信道上业务传输的其他的隶属STA，本申请对此不做限定。
第一设备中的与第二链路对应的隶属STA与第二设备中的与第二链路对应的隶属AP可传输第一设备与第二设备之间的业务，从而使得第一设备中的隶属STA能够在第二链路的工作频点对应的信道上与第二设备中的隶属AP传输业务，也使得第一设备可确定停止在第二链路的工作频点对应的信道上与第三设备中的隶属AP传输业务。
其中，第一设备与第二设备之间传输的业务可以包括一种或多种业务类型，本申请对业务的业务类型和数量不做限定。

第一设备中的与第四链路对应的隶属STA与第三设备中的与第四链路对应的隶属AP可停止传输第一设备与第三设备之间的全部业务类型的业务，从而使得第一设备中的隶属STA分别与第二设备中的隶属AP和第三设备中的隶属AP不会同时在第二链路或第四链路的工作频点对应的信道上传输业务。
其中，第一设备中的与第四链路对应的隶属STA可为第一设备中的与第二链路对应的隶属STA，也可为第一设备中的能够在第四链路的工作频点对应的信道上业务传输的其他的隶属STA，本申请对此不做限定。
其中，第一设备与第三设备之间传输的业务可以包括一种或多种业务类型，本申请对业务的业务类型和数量不做限定。
从而，通过第三链路可实现第一设备和第三设备的多链路连接。
综上，借助禁用部分链路的手段，为第一设备分别与第二设备和第三设备之间的业务传输提供可能，实现了第一设备分别与第二设备和第三设备的多链路连接，确保了第一设备与第二设备之间的业务传输，和第一设备与第三设备之间的业务传输不会在同一工作频点的信道上不会发生冲突。
图7为本申请一实施例提供的一种多链路并发连接方法的交互流程图。如图7所示，本申请提供的多链路并发连接方法可以包括：
S301、第一设备与第二设备通过第一链路集合建立多链路连接，第一链路集合包括第一链路和第二链路。

其中，S303与图3实施例中的S102实现方式类似，本申请此处不再赘述。
在第三链路和第一链路的工作频点相同，第四链路、第一链路和第二链路的工作频点皆不同时，第三链路和第一链路上不可同时进行业务传输，否则会造成业务传输的冲突。第四链路可进行业务传输。
作为一种可能的实现方式，第一设备与第二设备可禁用第一链路，启用第二链路。并且，第一设备与第三设备可启用第三链路，启用第四链路。
应理解，除上述方式之外，还可第三链路和第二链路的工作频点相同，第四链路、第一链路和第二链路的工作频点皆不同，即启用第一链路，禁用第二链路，且启用第三链路，启用第四链路，还可第四链路和第一链路的工作频点相同，第三链路、第一链路和第二链路的工作频点皆不同，即禁用第一链路，启用第二链路，且启用第三链路，启用第四链路，还可第四链路和第二链路的工作频点相同，第三链路、第一链路和第二链路的工作频点皆不同，即启用第一链路，禁用第二链路，且启用第三链路，启用第四链路。
另外，通常第一设备可禁用第一链路集合中的信道质量下降的链路。在禁用第一链路时，表示第一链路的信道质量下降。在禁用第二链路时，表示第二链路的信道质量下降。
或者，第一设备可根据用户配置，随机禁用第一链路集合中的一条或多条链路。
其中，上述的实现方式的工作原理相同或类似。为了便于解释，以禁用第一链路，启用第二链路，且启用第三链路，启用第四链路进行举例说明。
第一设备与第二设备在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务可参见S202实施例中相关的描述，此处不做赘述。
第一设备中的与第二链路对应的隶属STA与第二设备中的与第二链路对应的隶属AP可传输第一设备与第二设备之间的业务，从而使得第一设备中的隶属STA能够在第二链路的工作频点对 应的信道上与第二设备中的隶属AP传输业务。
从而，通过第二链路可实现第一设备和第二设备的多链路连接。
S304、第一设备与第三设备在第三链路和/或第四链路上传输第一设备与第三设备之间的业务。
S304中的第一设备与第三设备在第三链路上传输第一设备与第三设备之间的业务可参见S204实施例的相关的描述，此处不做赘述。
由于第四链路、第一链路和第二链路的工作频点皆不同。因此，第四链路、第一链路和第二链路对应的工作频点的信道不会发生业务传输冲突。这样，第一设备中的与第四链路对应的隶属STA与第三设备中的与第四链路对应的隶属AP可传输第一设备与第三设备之间的业务，从而使得第一设备中的隶属STA能够在第四链路的工作频点对应的信道上与第三设备中的隶属AP传输业务。
其中，第一设备中的与第四链路对应的隶属STA可为第一设备中的能够在第四链路的工作频点对应的信道上业务传输的隶属STA。第一设备中的与第四链路对应的隶属STA、与第一链路对应的隶属STA、与第二链路对应的隶属STA和与第三链路对应的隶属STA皆不同。
从而，根据网络情况、业务需求或设备情况等因素，通过第三链路和/或第四链路可实现第一设备和第三设备的多链路连接。
综上，借助禁用部分链路的手段，为第一设备分别与第二设备和第三设备之间的业务传输提供可能，实现了第一设备分别与第二设备和第三设备的多链路连接，确保了第一设备与第二设备之间的业务传输，和第一设备与第三设备之间的业务传输不会在同一工作频点的信道上不会发生冲突。
另外，图6和图7实施例的相同之处在于：第一设备皆通过复用与第二设备中的隶属AP业务传输的隶属STA，来与第三设备中的隶属AP传输业务，充分考虑到第一设备中的隶属STA较少的情况，降低了使用新的隶属STA所带来的资源消耗。图6和图7实施例的区别之处在于：图6中，第一设备中的隶属STA全部复用。图7中，第一设备中的隶属STA部分复用，引入了新的隶属STA。
图8为本申请一实施例提供的一种多链路并发连接方法的交互流程图。如图8所示，本申请提供的多链路并发连接方法可以包括：
S401、第一设备与第二设备通过第一链路集合建立多链路连接，第一链路集合包括第一链路和第二链路。

在第三链路、第一链路和第二链路的工作频点皆不同，第四链路和第一链路或者第二链路的工作频点相同时，第三链路可进行业务传输。第四链路和第一链路或第二链路上不可同时进行业务传输，否则会造成业务传输的冲突。
作为一种可能的实现方式，第一设备与第二设备可启用第一链路，启用第二链路。并且，第一设备与第三设备可启用第三链路，禁用第四链路。
应理解，除上述方式之外，还可第三链路和第一链路或者第二链路的工作频点相同，第四链路、第一链路和第二链路的工作频点皆不同，即启用第一链路，启用第二链路，且禁用第三链路，启用第四链路。
其中，上述的实现方式的工作原理相同或类似。为了便于解释，以启用第一链路，启用第二链路，且启用第三链路，禁用第四链路进行举例说明。
第一设备与第二设备在第一链路和第二链路上传输第一设备与第二设备之间的业务可参见S202实施例中的第一设备与第二设备在第二链路上传输第一设备与第二设备之间的业务的描述，此处不做赘述。

S404、第一设备与第三设备在第三链路上传输第一设备与第三设备之间的业务，在第四链路上停止传输第一设备与第三设备之间的全部业务类型的业务。
由于第三链路、第一链路和第二链路的工作频点皆不同。因此，第三链路、第一链路和第二链路对应的工作频点的信道不会发生业务传输冲突。这样，第一设备中的与第三链路对应的隶属STA与第三设备中的与第三链路对应的隶属AP可传输第一设备与第三设备之间的业务，从而使得第一设备中的隶属STA能够在第三链路的工作频点对应的信道上与第三设备中的隶属AP传输业务。
其中，第一设备中的与第三链路对应的隶属STA可为第一设备中的能够在第三链路的工作频点对应的信道上业务传输的隶属STA。第一设备中的与第三链路对应的隶属STA、与第一链路对应的隶属STA、与第二链路对应的隶属STA和与第四链路对应的隶属STA皆不同。
第一设备中的与第四链路对应的隶属STA与第三设备中的与第四链路对应的隶属AP可停止传输第一设备与第三设备之间的全部业务类型的业务，从而使得第一设备中的隶属STA分别与第二设备中的隶属AP和第三设备中的隶属AP不会同时在第二链路的工作频点对应的信道上传输业务，也使得第一设备中的隶属STA分别与第二设备中的隶属AP和第三设备中的隶属AP不会同时在第三链路的工作频点对应的信道上传输业务。
其中，第一设备中的与第四链路对应的隶属STA可为第一设备中的与第一链路对应的隶属STA，也可为第一设备中的与第二链路对应的隶属STA，也可为第一设备中的能够在第四链路的工作频点对应的信道上业务传输的其他的隶属STA，本申请对此不做限定。
从而，通过第三链路可实现第一设备和第三设备的多链路连接。
综上，借助第一设备中的未与第二设备进行业务传输的隶属STA、与第一链路集合中的链路皆不同的工作频点、或者与第一链路集合中的链路对应的工作频点皆不同的信道中的任意一种手段，为第一设备分别与第二设备和第三设备之间的业务传输提供可能，实现了第一设备分别与第二设备和第三设备的多链路连接，确保了第一设备与第二设备之间的业务传输，和第一设备与第三设备之间的业务传输不会在同一工作频点的信道上不会发生冲突。
另外，图8和图6-图7实施例的相同之处在于：第一设备分别与第二设备和第三设备传输业务时会避免在同一工作频点的信道上的冲突。图8和图6-图7实施例的区别之处在于：第一设备采用了不同的技术手段。
图9为本申请一实施例提供的一种多链路并发连接方法的交互流程图。如图9所示，本申请提供的多链路并发连接方法可以包括：
S501、第一设备与第二设备通过第一链路集合建立多链路连接，第一链路集合包括第一链路和第二链路。
其中，S501与图3实施例中的S101实现方式类似，本申请此处不再赘述。
S502、第一设备与第二设备在第一链路和第二链路上传输第一设备与第二设备之间的业务。
S503、第一设备与第三设备通过第二链路集合建立多链路连接，第二链路集合包括第三链路和第四链路；其中，第三链路、第一链路和第二链路的工作频点皆不同，第四链路、第一链路和第二链路的工作频点皆不同。
其中，S503与图3实施例中的S102实现方式类似，本申请此处不再赘述。

作为一种可能的实现方式，第一设备与第二设备可启用第一链路，启用第二链路。并且，第一设备与第三设备可启用第三链路，启用第四链路。
第一设备与第二设备在第一链路和第二链路上传输第一设备与第二设备之间的业务可参见S202实施例中的第一设备与第二设备在第二链路上传输第一设备与第二设备之间的业务的描述，此处不做赘述。
从而，通过第一链路和第二链路可实现第一设备和第二设备的多链路连接。
应理解，上述S502和S503之间没有时序上的先后顺序，且S502和S503可以同时执行，也 可以顺序执行。

S504中的第一设备与第三设备在第三链路和/或第四链路上传输第一设备与第三设备之间的业务可参见S304实施例的相关的描述，此处不做赘述。
从而，根据网络情况、业务需求或设备情况等因素，通过第三链路和/或第四链路可实现第一设备和第三设备的多链路连接。
综上，借助第一设备中的未与第二设备进行业务传输的隶属STA、与第一链路集合中的链路皆不同的工作频点、或者与第一链路集合中的链路对应的工作频点皆不同的信道中的任意一种手段，为第一设备分别与第二设备和第三设备之间的业务传输提供可能，实现了第一设备分别与第二设备和第三设备的多链路连接，确保了第一设备与第二设备之间的业务传输，和第一设备与第三设备之间的业务传输不会在同一工作频点的信道上不会发生冲突。
另外，图8和图9实施例的相同之处在于：第一设备中的与第二设备中的隶属AP业务传输的隶属STA，和第一设备中的与第三设备中的隶属AP传输业务的隶属STA存在不同，可充分利用第一设备中的隶属STA。图8和图9实施例的区别之处在于：图8中，前述的第一设备中的隶属STA部分不同，可存在复用。图9中，前述的第一设备中的隶属STA全部不同。
基于图6-图9实施例的描述，结合图10-图14，详细介绍第一设备分别借助禁用部分链路的手段和第一设备中的未与第二设备进行业务传输的隶属STA的手段的具体实现过程。
图10-图14为本申请一实施例提供的一种多个设备的交互示意图。
假设第一设备中包括的一个SAP为SAP1，SAP1对应的第一设备的MLD MAC地址为R。可选地，第一设备中包括的另一个SAP为SAP2，SAP2对应的第一设备的MLD MAC地址为S。第一设备中的隶属STA包括：STA1、STA2和STA3。其中，STA1的MAC地址(MAC address)
为y，STA2的MAC地址为z，STA3的MAC地址为t，y、z和t不同。
第二设备中包括的一个SAP对应的第二设备的MLD MAC地址为M。第一设备中的隶属AP包括：AP1和AP2。其中，AP1的MAC地址为w，AP2的MAC地址为x，w和x不同。
第三设备中包括的一个SAP对应的第三设备的MLD MAC地址为N。第一设备中的隶属AP包括：AP3和AP4。其中，AP3的MAC地址为p，AP4的MAC地址为q，p和q不同。
为了便于说明，图10中，MAC地址采用MAC addr，且链路采用Link进行示意。
如图10所示，STA1通过SAP1与AP1在Link1上建立连接，STA2通过SAP1与AP2在Link2上建立连接。其中，STA3未通过SAP1与第二设备中的隶属AP建立连接。
可见，第一设备通过Link1和Link2与第二设备建立多链路连接。
在确定启动多链路并发连接功能时，第一设备可禁用Link1，具体流程如下：
如图11所示，STA1通过SAP1与AP1在Link1上停止传输业务。在禁用Link1之后，STA1通过SAP2与AP3在Link3上建立连接，STA2通过SAP2与AP4在Link4上建立连接，且STA2通过SAP2与AP4在Link4上停止传输业务。
可见，第一设备通过Link3和Link4与第三设备建立多链路连接。
综上，第一设备与第二设备和第三设备可同时多链路连接，从而实现了第一设备的多链路并发连接功能。
并且，第一设备与第二设备可通过Link2传输业务，同时，第一设备与第三设备可通过Link3传输业务，从而实现了低时延或零中断的多网络并发连接场景。
如图12所示，STA1通过SAP1与AP1在Link1上断开连接，STA2通过SAP1与AP2在Link2上断开连接。在断开Link1和Link2后，STA2通过SAP2与AP4在Link2上启用业务传输。
综上，第一设备从多链路连接第二设备和第三设备切换到多链路连接第三设备，从而能够支持先连后断的漫游，实现了低时延或零中断的漫游场景。
应理解，上述过程仅为一种示例。
在确定启动多链路并发连接功能时，第一设备可借助STA3，具体流程如下：
如图13所示，STA3通过SAP2与AP4在Link4上建立连接，STA2通过SAP2与AP3在Link3上建立连接，且STA2通过SAP2与AP3在Link3上停止传输业务。
可见，第一设备通过Link3和Link4与第三设备建立多链路连接。
综上，第一设备与第二设备和第三设备可同时多链路连接，从而实现了第一设备的多链路并发连接功能。
并且，第一设备与第二设备可通过Link1和Link2传输业务，同时，第一设备与第三设备可通过Link4传输业务，从而实现了低时延或零中断的多网络并发连接场景。
如图14所示，STA1通过SAP1与AP1在Link1上断开连接，STA2通过SAP1与AP2在Link2上断开连接。在断开Link1和Link2后，STA2通过SAP2与AP3在Link3上启用业务传输。
综上，第一设备从多链路连接第二设备和第三设备切换到多链路连接第三设备，从而能够支持先连后断的漫游，实现了低时延或零中断的漫游场景。
应理解，上述过程仅为一种示例。
基于图4和图5实施例的描述，在执行S202或S302中的第一设备与第二设备在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务之前，第一设备和第二设备可需要禁用第一链路。
其中，禁用第一链路，可表示第一链路的信道质量下降。
下面，结合图15，详细介绍第一设备和第二设备禁用第一链路的具体实现方式。
图15为本申请一实施例提供的一种多链路并发连接方法的交互流程图。如图15所示，本申请提供的多链路并发连接方法可以包括：
S601、第一设备通过第一链路集合中的一条或多条链路向第二设备发送第一信息，第一信息用于请求在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务。
第一设备可从第一链路集合中选择一条或多条链路，如第一链路、第二链路、第一链路集合中的其他的链路、第一链路集合中的部分链路、或者第一链路集合中的全部链路等。
从而，第一设备中的与选择的链路对应的隶属STA可向第二设备中的与选择的链路对应的隶属AP发送第一信息。
S602、第二设备通过第一链路集合中的一条或多条链路向第一设备发送第二信息，第二信息用于确认在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务。
第二设备根据第一信息，可确认是否禁用第一链路。
在确认禁用第一链路之后，第二设备可从第一链路集合中选择一条或多条链路，如第一链路、第二链路、第一链路集合中的其他的链路、第一链路集合中的部分链路、或者第一链路集合中的全部链路等。
从而，第二设备中的与选择的链路对应的隶属AP可向第一设备中的与选择的链路对应的隶属STA发送第二信息，使得第一设备根据第二信息能够获知第二设备同意禁用第一链路。
由此，第一设备与第二设备可在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务。
其中，本申请对第一信息和第二信息的具体实现方式不做限定。
作为一种可能的实现方式，第一信息可携带在第一帧中，第二信息可携带在第二帧中。其中，第一帧或第二帧可为一帧或多帧。第一帧或第二帧可采用802.11系列标准中已存在的帧结构，如管理帧中的信标帧、探测请求帧、关联请求帧、重新关联请求帧、身份认证帧或其他格式的帧等，也采用802.11系列标准中新生成的帧结构，本申请对此不做限定。
另外，第一帧还可携带有第三信息，第三信息用于指示第二设备是否在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务。
其中，本申请对第三信息的具体实现方式不做限定。另外，第一信息和第三信息可采用第一帧中的相同或不同的元素或字段进行指示。
例如，第一帧为业务标识到链路映射请求帧(TID-to-link mapping request frame)，对应的，第二帧为业务标识到链路映射响应帧(TID-to-link mapping response frame)。
应理解，第二设备可支持业务标识到链路映射(TID-to-link mapping)的协商功能。
举例而言，业务标识到链路映射请求帧中的业务标识到链路映射元素(TID-to-link mapping element)可以包括：业务标识到链路映射控制(TID-to-link mapping control)字段和链路映射业 务标识(link mapping of TID n)字段，或者，业务标识到链路映射控制字段和链路映射业务标识扩展字段。
其中，n为整数，n的取值为大于或等于0且小于或等于7。
其中，业务标识到链路映射控制字段中的链路映射状态指示(link mapping presence indicator)子字段用于配置允许传输的业务的业务类型。
其中，链路映射业务指示字段或链路映射业务指示扩展字段用于配置第一链路集合中的每条链路允许传输的业务的业务类型，即可请求禁用第m条链路，m为第一链路的编号，m为整数。
考虑到在802.11系列标准中，链路映射业务标识字段的长度为16比特，即可支持16条链路的业务标识到链路映射(TID-to-link mapping)。基于此，第一设备可采用链路映射业务标识字段或者链路映射业务标识扩展字段可指示第一链路。
其中，链路映射业务标识扩展字段可支持大于16条链路的业务标识到链路映射。
如果第一设备与第二设备之间的链路的链路数量大于16时，第一设备可采用链路映射业务标识扩展字段可指示第一链路。
如果第一设备与第二设备之间的链路的链路数量小于或等于16时，第一设备可采用链路映射业务标识字段或者链路映射业务标识扩展字段可指示第一链路。
由此，第一设备通过业务标识到链路映射请求帧，可配置在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务，从而指示禁用第一链路。
此外，在一些实施例中，业务标识到链路映射响应帧中的状态码(status code)为0时，可表示第二设备同意禁用第一链路。
另外，考虑到802.11系列标准的差异，部分标准中的第二设备可选择同意禁用第一链路，也可选择不同意禁用第一链路。而本申请中，第二设备需要同意禁用第一链路。因此，在一些实施例中，业务标识到链路映射控制字段中的保留(reserved)子字段中的1比特或多个比特可用于配置第二设备是否在第一链路上停止传输第一设备与第二设备之间的全部业务类型的业务。
其中，保留子字段中的1比特或多个比特可为禁用标志(disabled flag)子字段，也可为其他的名称，本申请对此不做限定。当禁用标志子字段为1时，表示第二设备必须同意第一设备的请求。当禁用标志子字段为0时，表示第二设备可自行决策是否同意第一设备的请求。
从而，第一设备根据第三信息，可指示第二设备选择禁用第一链路还是必须禁用第一链路，即第二设备可选择是否同意第一设备禁用第一链路的请求，或者，第二设备可需要同意第一设备禁用第一链路的请求。
综上，第一设备和第二设备可禁用第一链路。
基于图4-图7实施例的描述，第一设备可分别与第二设备和第三设备实现多链路连接，能够支持多设备的多网络并发连接，从而可实现低时延或零中断的多网络并发连接场景。
随着网络情况、业务需求或设备情况等因素的改变，链路指标会随之发生变化。基于此，第一设备根据链路指标或者用户配置，可能需要继续需要实现多网络并发连接场景，也可能需要断开与第三设备的多链路连接，也可能需要实现漫游场景。
在第一链路、第二链路、第三链路和第四链路的信道质量基本不变的情况下，第一设备可继续分别与第二设备和第三设备实现多网络并发连接。
在第一链路和第二链路的信道质量优于第三链路和第四链路的信道质量的情况下，第一设备可与第三设备断开第二链路集合，第一设备可继续与第二设备实现多网络并发连接场景。
其中，第一设备与第三设备断开第二链路集合的具体实现方式可参见图16所示的S701中的第一设备与第二设备断开第一链路集合的描述，此处不做赘述。
在第三链路和第四链路的信道质量优于第一链路和第二链路的信道质量的情况下，由于第一设备能够支持先连后断的漫游，因此，第一设备可与第二设备断开第一链路集合，第一设备可继续与第三设备实现多网络并发连接，从而第一设备可实现漫游场景。
下面，结合图16，详细介绍第一设备实现漫游场景的具体实现方式。
图16为本申请一实施例提供的一种多链路并发连接方法的交互流程图。如图16所示，本申请提供的多链路并发连接方法可以包括：
S701、第一设备与第二设备断开第一链路集合。
第一设备中的多个隶属STA可与第二设备中的多个隶属AP断开第一链路集合中的全部链路，即第一设备和第二设备可拆除第一链路集合中的全部链路。
其中，拆除与建立相对。链路从无到有的过程，可称为建立。链路从有到无的过程，可称为拆除或断开。在链路建立后，链路可被启用，也可被禁用。
作为一种可能的实现，第一设备通过第一链路集合中的一个或多个链路向第二设备发送第十二信息，第十二信息用于指示拆除第一链路集合。
在图4-图5实施例的基础上，如果禁用第一链路，那么第一设备可从第一链路集合中的除第一链路之外的其他链路中选择一个或多个链路，来向第二设备发送第十二信息。在图6-图7实施例的基础上，如果启用第一链路和第二链路，那么第一设备可从第一链路集合中选择一个或多个链路，来向第二设备发送第十二信息。
其中，本申请对第十二信息的具体实现方式不做限定。
在一些实施例中，第四信息可携带在第十二帧中。其中，第十二帧可为一帧或多帧。第十二帧可采用802.11系列标准中已存在的帧结构，如管理帧中的信标帧、探测请求帧、关联请求帧、重新关联请求帧、身份认证帧、解除关联帧或其他格式的帧等，也采用802.11系列标准中新生成的帧结构，本申请对此不做限定。
例如，第十二帧为解除关联帧(disassociation frame)，解除关联帧用于指示断开第一链路集合。
S702、第一设备与第三设备在第三链路和/或第四链路上传输第一设备与第三设备之间的业务。
第一设备和第三设备可根据网络情况、业务需求或设备情况等因素，通过协商业务标识到链路映射(TID-to-link mapping)，从第三链路和/或第四链路中选择一条或多条链路传输第一设备与第三设备之间的业务。
也就是说，第一设备中的与选择的链路对应的隶属STA可与第三设备中的与选择的链路对应的隶属AP进行第一设备与第三设备之间的业务传输。
应理解，第一设备可支持业务标识到链路映射(TID-to-link mapping)的协商功能。
综上，第一设备可从多链路连接第二设备和第三设备切换到多链路连接第三设备，从而减少了漫游场景中由于先断后连而带来的中断时间，实现了低时延或零中断的漫游场景。
此外，在漫游场景或多网络并发连接场景中，第一设备与第三设备可能会在第四链路上传输第一设备与第三设备之间的业务。而基于图4和图6实施例的描述，第一设备与第三设备在第四链路上停止传输第一设备与第三设备之间的全部业务类型的业务。那么，第一设备与第三设备需要恢复启用第四链路。
下面，继续结合图16，在S702中的第一设备在第四链路上传输第一设备与第三设备之间的业务之前，本申请提供的多链路并发连接方法还可以包括：
S7031、第一设备通过第三链路向第三设备发送第四信息，第四信息用于请求在第四链路上传输第一设备与第三设备之间的业务。

S7032、第三设备通过第三链路向第一设备发送第五信息，第五信息用于确认在第四链路上传输第一设备与第三设备之间的业务。
第三设备根据第四信息，可确认是否启用第四链路。
在确认启用第四链路之后，第三设备中的与第三链路对应的隶属AP可向第一设备中的与第三链路对应的隶属STA发送第五信息，使得第一设备根据第五信息能够获知第三设备同意启用第四链路。
由此，第一设备与第三设备可在第四链路上传输第一设备与第三设备之间的业务。
其中，本申请对第四信息和第五信息的具体实现方式不做限定。
作为一种可能的实现方式，第四信息可携带在第四帧中，第五信息可携带在第五帧中。其中，第四帧或第五帧可为一帧或多帧。第四帧或第五帧可采用802.11系列标准中已存在的帧结构，如 管理帧中的信标帧、探测请求帧、关联请求帧、重新关联请求帧、身份认证帧或其他格式的帧等，也采用802.11系列标准中新生成的帧结构，本申请对此不做限定。
例如，第四帧为业务标识到链路映射请求帧(TID-to-link mapping request frame)，对应的，第五帧为业务标识到链路映射响应帧(TID-to-link mapping response frame)。
另外，上述的业务标识到链路映射请求帧请求恢复启用第四链路的具体实现方式可参见图8实施例中的业务标识到链路映射请求帧请求禁用第一链路的描述，上述的业务标识到链路映射响应帧的具体实现方式可参见图8实施例中的业务标识到链路映射响应帧的描述，此处不做赘述。
综上，第一设备与第三设备需要恢复启用第四链路。
基于图4和图6实施例的描述，第一设备和第三设备可启用第三链路，禁用第四链路。基于此，第一设备可在第三链路对应的工作频点的信道上请求第三设备建立第二链路集合且禁用第四链路。从而，第一设备可采用多种实现方式，通过第二链路集合与第三设备建立多链路连接。
下面，结合图17和图18，详细介绍第一设备通过第二链路集合与第三设备建立多链路连接的具体实现方式。

S803、第一设备通过第三链路向第三设备发送第八信息，第八信息用于请求建立第二链路集合。

在第一设备与第三设备建立第二链路集合时，第一设备可向第三设备通知第一设备中的能够与第三设备建立连接的链路，也可向第一设备通知第一设备中的全部链路，本申请对此不做限定。可选地，第一设备还可向第三设备通知禁用哪个或哪些链路、或者无法建立哪个或哪些链路等。对应的，第三设备可根据实际情况，从这些链路中选择部分或全部链路。第三设备可向第一设备通知这些链路。从而，第一设备与第三设备便可建立第二链路集合。
应理解，上述S804和S805之间没有时序上的先后顺序，且S804和S805可以同时执行，也可以顺序执行。
S806、第一设备通过第三链路向第三设备发送第十信息，第十信息用于请求在第四链路上停止传输第一设备与第三设备之间的全部业务类型的业务。
在建立第二链路集合之后，第一设备中的与第三链路对应的隶属STA可向第三设备中的与第三链路对应的隶属AP发送第十信息，使得第一设备。
应理解，如果除了第三链路和第四链路之外，第二链路集合还包括其他链路，那么第一设备可从第二链路集合中的除了第四链路之外的其他链路中选择一条或多条链路，如第三链路和/或其 他链路。
S807、第三设备根据第十信息，在第四链路上停止传输第一设备与第三设备之间的全部业务类型的业务。
