Description

服务时间调度的方法和装置
本申请要求于2019年08月09日提交中国专利局、申请号为201910736141.2、申请名称为“服务时间调度的方法和装置”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
本申请实施例涉及通信技术领域，尤其涉及一种服务时间调度的方法和装置。
背景技术
随着技术的快速发展，人们对实时业务的服务质量需求越来越高。现有协议中，站点(station，STA)只支持接收单个接入节点(access point，AP)服务。当STA处于移动场景中，单个AP可能无法满足STA的业务需求，导致服务通信质量降低，影响数据传输的可靠性。
因此，如何提高服务通信质量保证数据传输的可靠性成为亟待解决的问题。
发明内容
本申请提供一种服务时间调度的方法和装置，能够提高服务通信质量保证数据传输的可靠性。
第一方面，提供了一种服务时间调度的方法，包括：向服务接入节点AP发送第一服务请求帧，该第一服务请求帧包括用于请求多个AP服务的字段，其中，该请求多个AP服务的字段用于指示该多个AP在同一时段为站点STA进行服务；接收第一服务请求响应消息，该第一服务响应消息包括该多个AP的时间安排信息和/或该多个AP的信息元素，其中，该多个AP的时间安排信息用于指示该多个AP中每一个AP为该STA提供服务的服务时间，该多个AP的信息元素用于指示为该STA提供服务的AP。
上述技术方案中，STA直接发起多AP服务流程，服务AP向控制AP发送第一服务请求帧，控制AP确定为STA服务的多个AP，并统筹该多个AP的服务时间安排，从而实现多个AP在同一个SP中服务STA，提高通信服务质量。
结合第一方面，在第一方面的某些实现方式中，该第一服务请求帧还包括多个AP操作服务类型指示字段，其中，该多个AP操作类型指示字段用于指示该多个AP在同一时段服务STA的业务类型。
例如，该多个AP操作类型指示字段指示多个AP在同一时段为STA提供数据传输服务还是波束训练服务，或者，指示多个AP在同一时段为STA既提供数据传输服务也提供波束跟踪服务。
结合第一方面，在第一方面的某些实现方式中，该第一服务请求帧为以下至少一种：加入业务流请求帧；加入块确认请求帧；服务时间请求帧；多AP服务请求帧。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：发送第一帧，该第一帧包括第一字段，其中，该第一字段用于指示该STA有支持多AP服务的能力。
结合第一方面，在第一方面的某些实现方式中，该第一服务请求帧为加入业务流请求帧时，该加入业务流请求帧中预留字段用于指示请求多个AP服务服务，该加入业务流请求帧中的分配类型字段用于指示多个AP操作类型。
结合第一方面，在第一方面的某些实现方式中，该第一服务请求帧为加入块确认请求帧时，该加入块确认请求帧中预留字段用于指示请求多个AP服务和多个AP操作类型。
结合第一方面，在第一方面的某些实现方式中，该第一服务请求帧为服务时间请求帧时，该服务时间请求帧中动态分配信息元素中的预留字段用于指示请求多个AP服务，该动态分配信息元素中分配类型字段用于指示多个AP操作类型。
结合第一方面，在第一方面的某些实现方式中，多AP服务请求帧为预定义的帧。
第二方面，提供了一种服务时间调度的方法，包括：向控制接入节点AP发送第一服务请求帧，该第一服务请求帧包括用于请求多个接入节点AP服务的字段，其中，该请求多个AP服务的字段用于指示该多个AP在同一时段为站点STA进行服务；接收该控制AP发送的第一服务请求响应消息，该第一服务响应消息包括该多个AP的时间安排信息和/或该多个AP的信息元素，其中，该多个AP的时间安排信息用于指示该多个AP中每一个AP为该STA提供服务的服务时间，该多个AP的信息元素用于指示为该STA提供服务的AP；向该STA发送该第一服务请求响应消息。
结合第二方面，在第二方面的某些实现方式中，该第一服务请求帧还包括多个AP操作服务类型指示字段，其中，该多个AP操作类型指示字段用于指示该多个AP在同一时段服务STA的业务类型。
结合第二方面，在第二方面的某些实现方式中，该第一服务请求帧为以下至少一种：
加入业务流请求帧；加入块确认请求帧；服务时间请求帧；多AP服务请求帧。
结合第二方面，在第二方面的某些实现方式中，在该向控制接入节点发送第一服务请求帧之前，该方法还包括：接收该STA发送的该第一服务请求帧。
结合第二方面，在第二方面的某些实现方式中，在该向控制接入节点发送第一服务请求帧之前，该方法还包括：接收该STA发送的第二服务请求帧，该第二服务请求帧中包括该STA的需求参数，该STA支持多个AP服务；根据该STA的需求参数确定该服务AP不满足该STA的业务需求，向控制AP发送第二服务请求帧，接收该控制AP发送的第二服务请求响应消息，该第二服务请求响应消息包括以下信息中至少一项:该STA与该多个AP协商成功的指示信息；该多个AP操作类型指示信息；该多个AP的时间安排信息；该多个AP的信息元素。
其中，该第二服务请求帧包括STA的需求参数，例如，该STA请求的业务类型、频带等。该第二服务请求帧可以为加入业务流请求(add traffic stream request，ADDTS request)帧、加入块确认请求(add block acknowledgment request，ADDBA request)帧、服务时间请求(service period request，SPR)帧，该第二服务请求帧不携带多个AP服务的字段和该多个AP操作类型指示字段。
作为一种示例，控制AP在确定为该STA服务的多个AP后，将第二服务请求响应消息中的Status codes置为对应的类型。例如：“与多个AP协商成功 (SUCCESS_WITH_MULTIAP_SUPPORTED)”，表示多个AP与STA协商成功，区别于单个AP与STA协商成功的“成功(SUCCESS)”。
或者，控制AP通过公告(announce)帧将协商结果公告给该多个AP。
上述技术方案中，当STA的服务AP不能满足STA的业务需求时，服务AP向控制AP发送第一服务请求帧，控制AP确定为STA服务的多个AP，并统筹该多个AP的时间安排，从而实现多个AP在同一个SP中服务STA，提高通信服务质量。
结合第二方面，在第二方面的某些实现方式中，在该向控制接入节点发送第一服务请求帧之前，该方法还包括：向该STA发送该第一服务请求帧，该STA支持多个AP服务；接收该STA发送的第三服务响应消息，该第三服务响应消息包括该STA接受多个AP服务请求的指示信息。
上述技术方案中，无论服务AP是否能够满足STA的业务需求，若STA支持接收多AP服务，则服务AP可以直接发起多AP服务流程，从而实现多AP在同一SP内为一个STA服务，丰富了流程，提高了通信服务质量。
结合第二方面，在第二方面的某些实现方式中，该第一服务请求帧为加入业务流请求帧时，该加入业务流请求帧中预留字段用于指示请求多个AP服务服务，该加入业务流请求帧中的分配类型字段用于指示多个AP操作类型。
结合第二方面，在第二方面的某些实现方式中，该第一服务请求帧为加入块确认请求帧时，该加入块确认请求帧中预留字段用于指示请求多个AP服务和多个AP操作类型。
结合第二方面，在第二方面的某些实现方式中，该第一服务请求帧为服务时间请求帧时，该服务时间请求帧中动态分配信息元素中的预留字段用于指示请求多个AP服务，该动态分配信息元素中分配类型字段用于指示多个AP操作类型。
结合第二方面，在第二方面的某些实现方式中，多AP服务请求帧为预定义的帧。

结合第三方面，在第三方面的某些实现方式中，该第一服务请求帧还包括多个AP操作服务类型指示字段，其中，该多个AP操作类型指示字段用于指示该多个AP在同一时段服务STA的业务类型。

WLAN可以包括多个网络节点，例如，一个或多个接入点(access point，AP)和一个或多个站点(station，STA)。一个STA只能接入一个AP(即将STA与AP关联)，而一个AP下可以关联多个STA。STA和AP在进行数据传输之前，需要进行波束训练，获得该STA和AP之间的最优接收波束和/或最优发送波束。应理解，在波束训练过程中，通常将主动发起波束训练的一方称为发起设备，将被动进行波束训练的一方称为应答设备。本文后续提到的发起设备也可以称为发起方initiator，应答设备也可以称为应答方responder，下文不再一一说明。
具体地，以WLAN为例，本申请实施例中发起设备和应答设备是具有无线通信功能的设备，可以是WLAN中用户站点(station，STA)，该用户站点也可以称为用户单元、接入终端、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置或用户设备(user equipment，UE)。该STA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、个人数字助理(personal digital assistant，PDA)、具有无线局域网(例如Wi-Fi)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。
本申请实施例中的发起设备和应答设备也可以是WLAN中个人基本服务集控制点/接入点(personal basic service set control point/access point，PCP/AP)，PCP/AP可用于与接入终端通过无线局域网进行通信，并将接入终端的数据传输至网络侧，或将来自网络侧的数据传输至接入终端。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
以下，为了便于理解和说明，作为示例而非限定，将以本申请的用于切换的方法和装置在WLAN系统中的执行过程和动作进行说明。
下面先对本申请所涉及的相关技术进行介绍。
1、信标间隔(beacon interval，BI)
图1示出了信标间隔BI的结构示意图，如图1所示，信标间隔分为信标头指示(beacon header indication，BHI)和数据传输间隔(data transmission interval，DTI)。其中，BHI中又包括信标传输间隔(beacon transmission interval，BTI)、关联-波束赋形训练(association beamforming training，A-BFT)以及公告传输间隔(announcement transmission interval，ATI)。
具体地，PCP/AP会在BTI中按照扇区编号发送多个信标(beacon)帧，用于下行扇区扫描；A-BFT用于STA进行关联，以及上行扇区扫描；ATI用于PCP/AP向STA轮询缓存数据信息以及向STA分配数据传输间隔(data transmission interval，DTI)中的资源。整个DTI会被分为若干个子区间，子区间会根据接入的形式分为基于竞争接入期间(contention based access period，CBAP)和服务区间(service period，SP)，后者是进行调度传输，无需进行竞争。
2、波束赋形训练(beamforming training，BFT)
波束赋形训练又称为波束训练，具体可以包括扇区扫描(sector sweep，SSW)阶段和扇区扫描反馈(sector sweep feedback，SSW-Feedback)阶段。
(1)扇区扫描阶段：包括发起方扇区扫描(initiator sector sweep，ISS)阶段和应答方扇区扫描(responder sector sweep，RSS)阶段。其中，ISS阶段用来训练发起方的定向发送波束，发起方以一定宽度的波束定向发送训练数据，应答方准全向接收训练数据；RSS阶段用来训练应答方的定向发送波束，应答方以一定宽度的波束定向发送训练数据，并且包含了发起方上一阶段的最佳发送扇区信息，此时发起方准全向接收训练数据。上述训练数据可以为SSW帧。
(2)扇区扫描反馈阶段，反馈信息是按照扇区质量进行排序的发起方发送扇区列表，并且包含上一阶段应答方的最佳扇区，此时应答方处于准全向接收模式。
经过波束赋形训练，可以获得发起方和应答方之间的最优接收波束和/或最优发送波束。
图2示出了本申请实施例的一种通信系统的示意图。如图2所示，该通信系统包括多个AP。针对上述多个AP，其中的全部或部分AP的覆盖范围内还存在一个或多个STA。具体地，在图2所示的通信系统中，该通信系统共存在n个AP以及m个STA，m和n均为大于或等于1的整数。
应理解，上述通信系统可以针对移动场景，也可以针对非移动场景，即STA可以是移动的，也可以是固定的。因此，在STA可以移动的情况下，一个AP覆盖范围内的STA的数量可以是实时变化的，换句话说，可能存在某个时刻，存在某个AP并未覆盖到任何STA，本申请实施例对此不作限定。
在如图2所示的通信系统中，当STA移动至服务AP的服务边缘区域时，STA接收信号的强度降低甚至通信中断，通信服务可能会由于移动而中断，造成通信质量降低。
有鉴于此，本申请实施例提供了一种服务时间调度的方法，能够提高数据传输的可靠性，从而提高通信质量。
图3示出了本申请实施例提供的一种服务时间调度的方法300的示意性流程图。该方法300可以应用于图2所示的通信系统200中，但本申请实施例不限于此。
S310，STA向服务AP发送第一服务请求帧。
此时，无论服务AP是否满足STA的服务质量需求，STA可直接向服务AP发送第一服务请求帧，其中，该第一服务请求帧用于请求多个AP在一个服务周期SP内为一个STA进行服务，从而保证STA的高服务质量需求。
由于现有协议中，只支持单个AP为STA提供服务，因此，为了实现多个AP同时为一个STA提供服务的需求，该第一服务请求帧中需要包括用于请求多个AP服务的字段，其中，请求多个AP服务的字段用于指示多个AP在同一时段为STA进行服务。
需要说明的是，“字段用于指示”应理解为字段中的信息用于指示。例如，上述“请求多个AP服务的字段用于指示多个AP在同一时段为STA进行服务”实际上为请求多个AP服务的字段中的信息用于指示多个AP在同一时段为STA进行服务。
在一些可能的实现方式中，该第一服务请求帧还包括该多个AP操作类型指示字段，其中，多个AP操作类型指示字段用于指示该多个AP在同一时段服务STA的业务类型。例如，该多个AP操作类型指示字段指示多个AP在同一时段为STA提供数据传输服务还是波束训练服务，或者，指示多个AP在同一时段为STA既提供数据传输服务也提供波束跟踪服务。
在一些可能的实现方式中，该第一服务请求帧可以为加入业务流请求帧(add traffic stream request frame，ADDTS request frame)，相应地，该第一服务响应消息为加入业务流响应帧(add traffic stream response frame，ADDTS response frame)。

S1020，STA确定是否支持多AP服务请求。
接收到服务AP发送的第一服务请求帧后，该STA确定自身是否支持多AP服务请求。

在一些可能的实现方式中，可以在STA发送给AP的关联/重关联(association/reassociation request)帧中增加字段指示STA支持多AP服务的能力。
