Abstract

本申请实施例公开了一种时频资源的分配方法及相关设备。本申请实施例方法包括：首先，AP获取与AP关联的第一STA的第一状态信息，该第一状态信息包括第一STA进入休眠状态。之后，AP向接入管理设备发送第一消息，第一消息用于指示第一STA进入休眠状态。进而，接入管理设备根据第一消息更新本地维护的第一STA的状态信息，并进行时频资源调度以将第一时频资源分配给处于唤醒状态的STA。通过上述方式，就算第一AP与第一STA之间具有待传输的数据，也不会占用时频资源与进入休眠状态的第一STA进行数据交互，避免了时频资源的浪费。

Description

一种时频资源的分配方法及相关设备
本申请要求于2022年1月26日提交中国国家知识产权局、申请号为202210096407.3、申请名称为“一种时频资源的分配方法及相关设备”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
本申请涉及通信领域，尤其涉及一种时频资源的分配方法及相关设备。
背景技术
光纤到房间(fiber to the room，FTTR)是一种新的家庭网络接入架构，将光纤从信号箱拉出布放到每一个房间，光猫通过每个房间的光纤接入到光网关并为用户提供可靠的无线接入点(access point，AP)，让无线信号覆盖到家庭场景的每一个角落。随着FTTR架构的不断演进，通过光网关控制光猫进行下行时频资源分配以及站点(station，STA)上行接入管控的两层集中式调度架构被提出。光网关会根据光猫上报的空口信息、缓存信息以及业务类型向光猫下发指令，以为STA分配时频资源。
然而，STA的节能状态由光猫独立维护与更新，假设光猫缓存有休眠状态STA对应的下行数据，光猫将缓存信息以及业务类型上报到光网关后，光网关认为可以为该STA分配时频资源并发送调度决策到光猫。但是，由于STA处于休眠状态，STA并不会接收光猫发送的数据，导致时频资源的浪费。
发明内容
本申请提供了一种时频资源的分配方法及相关设备，避免了时频资源的浪费。
第一方面，本申请提供了一种时频资源的分配方法。该方法由接入管理设备执行。首先，接入管理设备接收第一AP发送的第一消息。其中，该第一消息用于指示与第一AP关联的第一STA进入休眠状态。进而，接入管理设备根据第一消息确定所述第一STA处于休眠状态，并进行时频资源调度，以将第一时频资源分配给处于唤醒状态的STA。
在该实施方式中，第一AP可以获知第一STA处于唤醒状态还是休眠状态。如果第一STA从唤醒状态进入休眠状态，第一AP会向接入管理设备发送消息以通知第一STA进入休眠状态。接入管理设备就不会为第一STA分配时频资源，这样一来，就算第一AP与第一STA之间具有待传输的数据，也不会占用时频资源与进入休眠状态的第一STA进行数据交互，避免了时频资源的浪费。
在一些可能的实施方式中，与第一AP关联的第二STA处于唤醒状态，接入管理设备将第一时频资源分配给处于唤醒状态的STA包括：接入管理设备向第一AP发送第一调度消息，第一调度消息用于指示第一AP采用第一时频资源与处于唤醒状态的第二STA进行数据交互。在该实施方式中，提供了一种接入管理设备分配时频资源的具体实施方式，增强了本方案的实用性。
在一些可能的实施方式中，接入管理设备与第二AP关联，与第二AP关联的第二STA处于唤醒状态，接入管理设备将第一时频资源分配给处于唤醒状态的STA包括：接入管理设备向第二AP发送第一调度消息，第一调度消息用于指示第二AP采用第一时频资源与处于唤醒状态的第二STA进行数据交互。在该实施方式中，提供了另一种接入管理设备分配时频资源的具体实施方式，如果包括第一STA在内与第一AP关联的所有STA都进入休眠状态，第一AP暂时将不再参与资源调度，接入管理设备将第一时频资源分配给与第二STA关联的第二STA，提高了本方案的灵活性。
在一些可能的实施方式中，第一消息包括第一消息类型、第一AP的标识和第一STA的标识。在该实施方式中，介绍了第一消息所携带的内容，便于接入管理设备根据第一消息制定调度策略。
在一些可能的实施方式中，第一消息为光网络单元管理控制接口(ONU management and control interface，OMCI)消息，第一消息包括第一消息类型字段和第一消息内容字段，第一消息类型字段指示第一消息类型，第一消息内容字段指示第一AP的标识和第一STA的标识。在该实施方式中，第一消息可以采用现有标准中定义的OMCI消息格式，便于本方案进行标准化实现。
在一些可能的实施方式中，第一消息为以太网帧，第一消息包括第一类型长度字段和第一负载字段，第一类型长度字段指示第一消息类型，第一负载字段指示第一AP的标识和第一STA的标识。在该实施方式中，第一消息可以采用现有标准中定义的以太网帧格式承载，便于本方案进行标准化实现，并提高了本方案的扩展性。
在一些可能的实施方式中，方法还包括：接入管理设备接收第一AP发送的第二消息，第二消息用于指示第一STA进入唤醒状态。接入管理设备根据第二消息确定所述第一STA处于唤醒状态，并向第一AP发送第二调度消息，第二调度消息用于指示第一AP采用第二时频资源与处于唤醒状态的第一STA进行数据交互。在该实施方式中，若第一STA从休眠状态又切换到唤醒状态，第一AP也会通知接入管理设备，以便接入管理设备重新为第一STA分配时频资源，以保证第一AP与第一STA可以正常进行数据交互。
在一些可能的实施方式中，第二消息包括第一AP与第一STA之间待传输的数据大小和流量身份标记(Traffic Identification，TID)，以便于接入管理设备根据实际需要更合理地为第一STA分配时频资源。
在一些可能的实施方式中，接入管理设备接收第一AP发送的第一消息之前，第一时频资源由接入管理设备预分配给第一STA。在该实施方式中，提供了一种具体的应用场景，第一STA处于唤醒状态时，接入管理设备可以将第一时频资源预分配给第一STA。其中，这种预分配的操作可以理解为接入管理设备本地的调度决策，并不一定通过调度实际将第一时频资源预分配给第一STA。在第一STA切换到休眠状态后，接入管理设备将重新调整调到决策，以将第一时频资源分配给处于唤醒状态的其他STA，保证了第一时频资源能有得到有效利用。
在一些可能的实施方式中，接入管理设备是光网关，第一AP是光猫。或者，接入管理设备是光线路终端(optical line terminal，OLT)，第一AP是光网络单元(optical network unit，ONU)。在该实施方式中，本方案应用于光接入场景，具体可以是FTTR的场景，实现了家庭网络的WIFI覆盖，并实现了该场景下时频资源的合理调配。
在一些可能的实施方式中，本方案应用于铜线接入场景，接入管理设备是接入控制器(accesscontroller，AC)，AC通过铜线与AP连接，扩展了本本方案适用的场景。
第二方面，本申请提供了一种时频资源的分配方法。该方法由AP执行。首先，AP获取与AP关联的第一STA的第一状态信息，该第一状态信息包括第一STA进入休眠状态。进而，AP向接入管理设备发送第一消息，第一消息用于指示第一STA进入休眠状态，以使得接入管理设备确定所述第一STA处于休眠状态，并将第一时频资源分配给处于唤醒状态的STA。
在一些可能的实施方式中，与AP关联的第二STA处于唤醒状态，方法还包括：AP接收接入管理设备发送的第一调度消息。AP采用第一调度消息指示的第一时频资源与处于唤醒状态的第二STA进行数据交互。
在一些可能的实施方式中，第一消息包括第一消息类型、第一AP的标识和第一STA的标识。
在一些可能的实施方式中，第一消息为OMCI消息，第一消息包括第一消息类型字段和第一消息内容字段，第一消息类型字段指示第一消息类型，第一消息内容字段指示AP的标识和第一STA的标识。
在一些可能的实施方式中，第一消息为以太网帧，第一消息包括第一类型长度字段和第一负载字段，第一类型长度字段指示第一消息类型，第一负载字段指示AP的标识和第一STA的标识。
在一些可能的实施方式中，更新后的第一状态信息包括第一STA进入唤醒状态，方法还包括：AP向接入管理设备发送第二消息，第二消息用于指示第一STA进入唤醒状态。AP接收接入管理设备发送的第二调度消息。AP采用第二调度消息指示的第二时频资源与处于唤醒状态的第一STA进行数据交互。
在一些可能的实施方式中，第二消息包括AP与第一STA之间待传输的数据大小和TID。
在一些可能的实施方式中，AP获取第一STA的第一状态信息之前，第一时频资源由接入管理设备预分配给第一STA。
在一些可能的实施方式中，接入管理设备是光网关，AP是光猫。或者，接入管理设备是OLT，AP是ONU。
在一些可能的实施方式中，接入管理设备是AC。

具体实施方式
本申请提供了一种时频资源的分配方法及相关设备，避免了时频资源的浪费。需要说明的是，本申请说明书和权利要求书及上述附图中的术语“第一”、“第二”等用于区别类似的对象，而非限定特定的顺序或先后次序。应该理解，上述术语在适当情况下可以互换，以便在本申请描述的实施例能够以除了在本申请描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
无源光网络(passive optical network，PON)是光接入网的一种实现技术，PON是一种点对多点传送的光接入技术。当前的PON系统主要用于光纤到户(fiber to the home，FTTH)场景，每个家庭用户只会有一个光网络单元(optical network unit，ONU)。
图1为FTTH的系统架构示意图。光线路终端(optical line terminal，OLT)连接上层的网络侧设备(如交换机、路由器等)，下层连接一个或者多个光分配网络(optical distribution network，ODN)。ODN包括用于光功率分配的无源光分光器、连接在无源光分光器和OLT之间的主干光纤，以及连接在无源光分光器和ONU之间的分支光纤。下行传输数据时，ODN将OLT下行的数据通过分光器传输到各个ONU，ONU选择性接收携带自身标识的下行数据。上行传输数据时，ODN将N路ONU发送的光信号组合成一路光信号传输到OLT。ONU为OAN提供用户侧接口，同时与ODN相连。如果ONU同时提供用户端口功能，如ONU提供以太网用户端口或者传统电话业务(plain old telephone service，POTS)用户端口，则称为光网络终端(optical network termination，ONT)。
在FTTH的基础上，为了解决家庭网络WIFI覆盖的问题，还可以把光纤进一步延伸至住户房间内。在房间内部安装ONU，这样就缩小了用户终端与ONU的距离，提高了信号质量。这种应用场景称之为光纤到房间(fiber to the room，FTTR)。
图2为FTTR的系统架构示意图。FTTR网络和FTTH网络可以看作是两级PON系统。第一级PON系统(FTTH)中的OLT部署在中心机房，ONU部署在家庭的信息箱中。第二级PON系统(FTTR)中的OLT可以代替FTTH中的ONU部署在家庭的信息箱中，该OLT在FTTR场景中具备与FTTH场景中OLT的类似功能，同时该OLT也可以具备与FTTH场景中ONU的类似功能。也即是说，FTTR中的OLT可以作为FTTH和FTTR之间起承上启下作用的网络设备。FTTR中的ONU可以部署在家庭的各房间内，用于和用户终端之间相连，该ONU和FTTH中的ONU在本质上是同一类型的网络设备。不同的是，FTTH中ONU一般部署在信息箱内，与用户终端之间通常还会相隔一个接入点(accesspoint，AP)。而FTTR中ONU进入每个房间，并且该ONU还具备AP的功能，可直接与用户终端进行WiFi连接。
应理解，在FTTR中，OLT可以实现对所有ONU的统一管理和配置。例如，OLT可以给与ONU关联的用户终端分配上下行的时频资源，用于ONU与用户终端进行数据交互。需要说明的是，在FTTR中，OLT也可以称之为“光网关”，ONU也可以称之为“光猫”或“边缘ONU”，本申请不限定其具体的名称。
还应理解，本申请所提供的时频资源的分配方法除了可应用于上述介绍的光接入场景外，还可以应用于铜线接入场景。例如，采用接入控制器(accesscontroller，AC)代替上述的OLT，AC通过铜线与所有AP连接，AC对所有AP进行统一管理和配置。
为了便于介绍，下文中统一将OLT、光网关和AC称之为“接入管理设备”，将ONU和光猫称之为“AP”，将与AP关联的用户终端称之为“站点(station，STA)”。
图3为本申请中时频资源的分配方法的第一个实施例示意图。在该示例中，时频资源的分配方法包括如下步骤。
301、第一AP获取第一STA的节能状态信息。
本实施例中，第一AP与第一STA关联，第一AP本地存储有第一STA的节能状态信息，其中，该节能状态信息用于反映第一STA处于唤醒状态或休眠状态。当第一STA的节能状态发生改变时，第一STA会通知第一AP，进而第一AP更新本地存储的第一STA的节能状态信息。在本实施例中，第一STA的节能状态信息为第一STA进入休眠状态。需要说明的是，当 前的标准中定义了很多AP与STA之间的节能交互机制，例如，802.11协议中定义的快速省电(fast power save)机制，本申请不限定第一AP获取第一STA的节能状态信息的具体实现方式。
302、第一AP向接入管理设备发送第一消息。
第一AP向接入管理设备发送的第一消息用于指示与第一AP关联的第一STA进入休眠状态。图4为本申请中第一消息的第一种帧结构示意图。如图4所示，第一消息包括第一消息类型、第一AP的标识和第一STA的标识。其中，接入管理设备可以根据第一消息类型获知该第一消息是反映STA节能状态的消息，并根据第一AP的标识和第一STA的标识获知该第一消息反映的是与第一AP关联的第一STA的节能状态。作为一种实现方式，上述第一消息类型可以作为一个独立的字段直接指示STA进入休眠状态。作为另一种实现方式，上述第一消息类型作为一个独立的字段仅用于指示该第一消息的类型，在此基础上还将结合第一消息中的其他指定字段指示STA进入休眠状态，例如该指定字段包括1个比特位，若该比特位是0则表示唤醒状态，若该比特位是1则表示休眠状态。应理解，第一消息除了包括上述介绍的内容外，还可以包括消息标识等其他内容，具体此处不做限定。
需要说明的是，上述第一消息可以采用新定义的消息结构，也可以采用现有标准中定义的消息结构。下面结合示例介绍几种第一消息采用现有标准中消息结构的实施方式。
实施方式1：第一消息采用光网络单元管理控制接口(ONU management and control interface，OMCI)消息。
图5为本申请中第一消息的第二种帧结构示意图。如图5所示，采用吉比特无源光网络封装方法(gigabit passive optical network encapsulation method，GPON)封装的OMCI消息包括：GEM帧头(GPON encapsulation method header，GEM header)，用于指示帧开始。处理相关标识符(transaction correlation identifier)：一组对应请求和响应的消息。消息类型(message type)：用于定义消息类型。设备类型(device identifier)：其中，0xA表示Baseline类，0xB表示Extend类。消息标识符(message identifier)：大小为4字节，两字节的实体ID，两字节的实例ID。消息内容(message contents)：用于表示帧净荷。OMCI尾部(OMCItrailer)：主要用来填充校验码。在该实施方式中，消息类型字段指示第一消息类型，本申请可以在现有标准已经定义的消息类型中新增一种消息类型，用于AP向接入管理设备上报STA的节能状态。作为一个示例，可以将消息类型字段设置为0x1d。并且，对消息内容字段也进行了定义，通过消息内容字段可以指示第一AP的标识和第一STA的标识。
实施方式2：第一消息通过以太网帧承载。
图6为本申请中第一消息的第三种帧结构示意图。如图6所示，以太网帧包括：目的地址(destination address)、源地址(source address)、类型长度(type/length)和负载(data)。其中，类型长度字段指示第一消息类型，本申请可以在现有标准已经定义的消息类型中新增一种消息类型，用于AP向接入管理设备上报STA的节能状态。作为一个示例，可以将类型长度字段设置为0xAABB。并且，对负载字段也进行了定义，通过负载字段可以指示第一AP的标识和第一STA的标识。
需要说明的是，若本申请应用于光接入的PON系统中，上述第一消息既可以采用OMCI的消息格式，也可以通过OMCI消息上一层的以太网帧承载。若本申请应用于铜线接入场景中，上述第一消息将通过以太网帧承载。
303、接入管理设备根据第一消息确定第一STA处于休眠状态，并将第一时频资源分配给处于唤醒状态的STA。
本实施例中，接入管理设备可以根据第一消息获知与第一AP关联的第一STA进入休眠状态，那么，接入管理设备可以将第一时频资源分配给当前处于唤醒状态的其他STA。
应理解，在一种可能的实施方式中，第一STA在进入休眠状态之前与第一STA之间具有待传输数据，第一AP可以将与待传输数据相关的信息上报至接入管理设备，接入管理设备会认为第一STA可以参与调度。例如，接入管理设备可以将第一时频资源预分配给第一STA。其中，这种预分配的操作可以理解为接入管理设备本地的调度决策，并不一定通过调度实际将第一时频资源预分配给第一STA。在第一STA切换到休眠状态后，接入管理设备将重新调整调度决策，以将第一时频资源分配给处于唤醒状态的其他STA。又例如，接入管理设备通过实际的调度操作为第一STA分配了时频资源，在第一STA切换到休眠状态后，接入管理设备暂时将不再为第一STA分配时频资源。
需要说明的是，在实际应用中，就算第一AP与第一STA没有进行数据交互或者第一AP与第一STA之间没有待传输的数据，第一AP也可以获取第一STA的节能状态信息并上报给接入管理设备，那么接入管理设备就不会为第一STA分配时频资源。也就是说，无论当前第一AP与第一STA是否要进行数据交互，只要第一STA进入休眠状态第一AP就会通知接入管理设备，在第一STA重新唤醒之前接入管理设备将不再为第一STA分配时频资源。
下面将结合几种具体应用场景对接入管理设备分配第一时频资源的方式进行介绍。
应用场景1：接入管理设备给与第一AP关联的第二STA分配时频资源。
本实施例中，与第一AP关联的第二STA处于唤醒状态，且第一AP与第二STA之间具有待传输的数据。由于第一AP不会通知接入管理设备第二STA进入休眠状态，接入管理设备会确定第二STA处于唤醒状态并给第二STA分配时频资源。具体地，接入管理设备向第一AP发送第一调度消息，第一AP采用第一调度消息指示的第一时频资源与第二STA进行数据交互。
应用场景2：接入管理设备给与第二AP关联的第二STA分配时频资源。
本实施例中，包括第一STA在内与第一AP关联的所有STA都进入休眠状态，第一AP暂时将不再参与接入管理设备的调度决策。应理解，接入管理设备本地存储有与之关联的所有AP的状态信息。作为一个示例，图7为本申请中AP的状态信息的内容示意图。如图7所示，AP的状态信息包括：AP的标识、调度标记、STA的标识、节能标记、调制与编码策略(Modulation and Coding Strategy，MCS)、流量身份标记(Traffic Identification，TID)和待传输数据大小。该待传输数据包括上行数据和/或下行数据。其中，调度标记用于指示AP是否能参与接入管理设备的调度决策，例如，调度标记为0表示AP不能参与接入管理设备的调度决策，调度标记为1表示AP可以参与接入管理设备的调度决策。节能标记用于指示与AP关联的STA的节能状态，例如，节能标记为0表示STA处于唤醒状态，节能标记为1表示STA处于休眠状态。流量身份标记用于指示AP与STA之间传输的各业务类型。接入管理设备通过对比各AP的状态信息可以确定与第二AP关联的第二STA处于唤醒状态并给第二STA分配时频资源。具体地，接入管理设备向第二AP发送第一调度消息，第二AP采用第一调度消息指示的第一时频资源与第二STA进行数据交互。
本申请实施例中，第一AP可以获知第一STA处于唤醒状态还是休眠状态。如果第一STA从唤醒状态进入休眠状态，第一AP会向接入管理设备发送消息以通知第一STA进入休眠状态。进而，接入管理设备将根据第一AP上报的消息进行时频资源调度，以将时频资源分配给处于唤醒状态的STA。这样一来，就算第一AP与第一STA之间具有待传输的数据，也不会占用时频资源与进入休眠状态的第一STA进行数据交互，避免了时频资源的浪费。
需要说明的是，如果与第一AP关联的第一STA又从休眠状态切换到唤醒状态，第一AP也会通知接入管理设备，进而接入管理设备将重新为第一STA分配时频资源。下面通过具体实施例进行介绍。
图8为本申请中时频资源的分配方法的第二个实施例示意图。在该示例中，时频资源的分配方法包括如下步骤。
801、第一AP获取第一STA的节能状态信息。
当第一STA的节能状态发生改变时，第一STA会通知第一AP，进而第一AP更新本地存储的第一STA的节能状态信息。在本实施例中，第一STA的节能状态信息为第一STA进入唤醒状态。应理解，第一AP获取第一STA的节能状态信息的具体实现方式可以参考图3所示实施例中步骤303的相关描述，此处不再赘述。
802、第一AP向接入管理设备发送第二消息。
第一AP向接入管理设备发送的第二消息用于指示与第一AP关联的第一STA进入唤醒状态。应理解，本实施例中的第二消息与上述图3所示实施例中的第一消息的消息格式是类似的，区别只在于指示的内容不同。其中，第二消息包括第二消息类型、第一AP的标识和第一STA的标识。关于第二消息的格式可以参考图3所示实施例中对第一消息格式的相关介绍，此处不再赘述。
在一些可能的实施方式中，第二消息还可以包括MCS、TID和第一AP与第一STA之间待传输的数据大小，以便于接入管理设备根据实际需要更合理地为第一STA分配时频资源。需要说明的是，若第二消息采用如上述图5所示的消息格式，则MCS、TID和待传输数据大小承载在消息内容字段。若第二消息采用如上述图6所示的消息格式，则MCS、TID和待传输数据大小承载在负载字段。
803、接入管理设备向第一AP发送第二调度消息。
接入管理设备根据第一AP上报的第二消息更新本地存储的第一STA的状态信息。以上述图7为例，由于第一STA进入唤醒状态，节能标记将置0表示第一STA处于唤醒状态，并且调度标记为1表示第一AP可以参与接入管理设备的调度决策。进而，接入管理设备可以根据第二消息中的MCS、TID和待传输数据大小等信息为第一STA分配第二时频资源，并向第一AP发送第二调度消息，以通知本次的调度决策。
804、第一AP采用第二时频资源与第一STA进行数据交互。
第一AP采用第二调度消息指示的第二时频资源与第一STA进行数据交互。
