Description

无线网络接入的方法及装置、终端设备 技术领域
本发明涉及无线通信技术领域，尤其涉及一种时分无线覆盖系统的无线网络接入的方法及装置、终端设备。
背景技术
TDMA(Time Division Multiple Access，时分多址)是一种为实现共享传输介质或者网络的无线通信技术，它允许多个用户在不同的时间片来使用相同的频率，例如GSM(Global System for Mobile Communication，全球移动通信系统)系统和WLAN(WirelessLocal Area NetWork，无线局域网)系统。其中GSM系统中的最小时间片为一个时隙，时隙长度为固定值，由时隙组成的超高帧也为固定长度，GSM系统中还需要配置不同控制信道使用的时隙，用户实际用于发送数据的时间片受限；而WLAN系统采用的IEEE 802.11标准中有两种信道接入方法：一种是DCF(Distributed Coordination Function，分布式协调功能)——自动高效的共享媒体，另外一种是PCF(Point Coordination Function，点协调)——支持近乎实时的应用；其中DCF是以CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance，载波侦听多路访问/冲突避免)为基本的接入方式，尽可能避免冲突，CSMA/CA是载波侦听机制，分物理载波侦听(由物理层提供，若报告“媒介忙”；否则媒介空，基于能量感知和信号特性感知)和虚拟载波侦听NAV(Network Allocation Vector，网络分配矢量)两种，媒介空闲剩余时间值，由MAC data frame的Duration字段来提供媒体预留信息，实质为一个计时器，为0表示空闲，当侦听到媒介闲置时间大于了DIFS(Distributed Inter-frame Spacing，分布式帧间间隔)，终端立即进行传输；若侦听到媒介忙碌，等候至再度闲置DIFS，同时准备指数退避过程。DCF无论如何都需要进行侦听来获取信道是否空闲或忙碌，并且用户发生竞争的时间过长，在一定程度上造成了资源的浪费，且由于DCF仅提供尽力而为的服务，无法满足实时业务对时延和抖动等指标的需求；与此同时，该方式将会导致不同AP之间由于用户的不同时竞争接入，上下行数据收发不同步，容易造成不同AP间上下行时长交叉干扰问题存在；
为了提供延迟受限的服务，IEEE 802.11标准在DCF的基础上定义了PCF，其基本原理是利用点协调器PC(Point Coordination)对节点进行轮询，集中控 制介质的访问，由接入点AP(Access Point)来担任点协调器。PCF以超帧为周期来进行数据帧的发送，每个超帧周期包括一个无竞争阶段CFP(Contention-Free Period)和一个竞争阶段CP(Contention Period)，CFP阶段传输实时业务，PCF起作用，CP阶段传输非实时业务，DCF起作用；但是在CFP期间，AP仍然要侦听媒介，需要AP检测出信道空闲时间达到PIFS(PCF Inter-frame Spacing，点协调功能帧间间隔)后，AP发送一个包含CF(Coordination Function，协调功能)参数集信息的信标帧，发出初始化CFP的信标帧之后，AP至少等待一个SIFS(Short Inter-frame Spacing，短帧间间隔)，然后根据情况发送数据帧或轮询帧；AP根据轮询列表分别询问关联的终端设备，而终端设备必须在得到轮询后才能传送数据；该种方式需要AP确定CFP发起时间，以及AP需要发送轮询帧告知终端设备是否有权发送数据，在一定程度上仍然存在资源的浪费，且用户数据调度的实时性仍然无法得到保障；而且在CFP期间，终端设备需要一直侦听轮询帧是否有发送给自己，因此终端设备功耗上存在浪费。

另外，本发明实施例中AP集中分配广播信息发送、上/下行数据、竞争接 入的时长和位置，提高资源利用率，减少竞争接入和正常上行数据发送的冲突碰撞，提高竞争接入的成功概率，减少已接入终端设备等待上行数据发送的时长，降低业务传输时延，提高终端设备业务质量和感知。
本发明实施例中，所述各业务类型包括广播业务、上行数据业务、下行数据业务、竞争接入业务。相应的，步骤S11中确定无线访问接入点AP的工作周期通过以下步骤实现，具体如下：在所述工作周期的初始位置分配广播业务对应的广播信息时长，并基于工作周期剩余时长分配所述广播业务以外的其他业务对应的时长和分布位置。
在实际应用中，接入装置具体可以根据接入装置的覆盖范围内各终端设备的上、下行业务需求，分别在上行数据业务对应的上行数据时长和下行数据业务对应的下行数据时长内为各终端设备分配上、下行时隙资源。
本实施例中的工作周期为接入点的工作周期。该工作周期包含广播信息时长，下行数据时长，上行数据时长以及竞争接入时长。在分配广播业务对应的广播信息时长之前，可根据用户业务时延参数以及用户数量配置所述工作周期的时长。本实施例中，AP可以根据用户业务时延要求以及用户数量进行工作周期的配置，可以配置为固定值，例如5ms为一个工作周期，也可以基于一定策略进行动态调整。

S114、根据预设的系统配置参数确定所述竞争接入时长、上行数据时长和下行数据时长在所述工作周期中的位置。
进一步地，若所述上行数据时长和下行数据时长相邻，则所述上行数据时长和下行数据时长之间包括有第一指定长度的保护时长。
进一步地，在所述上行数据时长中每一时隙的初始位置分配第二指定长度的保护时长；在所述下行数据时长中每一时隙的初始位置分配第三指定长度的保护时长；在所述竞争接入时长的初始位置分配第四指定长度的保护时长。本实施例中，上行数据时长中每一时隙的初始位置包括有第二指定长度的保护时长。下行数据时长中每一时隙的初始位置包括有第三指定长度的保护时长。竞争接入时长的初始位置包括有第四指定长度的保护时长。
在一个具体实施例中，竞争接入时长与AP覆盖范围内最远的终端设备发起关联请求所需的往返时间有关，可供根据覆盖范围内距离AP最远的终端设备发起关联请求所需的往返时间进行确定。为保障与其他已接入终端设备的上行数据发送不冲突，竞争接入时长的初始位置包括有第四指定长度的保护时长。可以在预留竞争接入时长之前预留保护时长GP3，该时长也可以根据发送距离进行设定；例如设定GP3＝50us，竞争接入时长设定为100us。
下行数据时长是AP在工作周期内用来发送下行数据的总时长，上行数据时长是终端设备在工作周期内用来发送上行数据的总时长，这两个时长可以基于(工作周期-广播信息时长-竞争接入时长)的剩余时长再结合上下时长比例进行分配；上下时长比例为预先设置的系统配置参数，可固定配置或者动态配置；该比例可以根据上下行业务量或者信道质量确定；例如：工作周期＝5ms，广播信息时长＝250us，竞争接入总时长＝50+100＝150us，那么剩余时长＝5000-250-150＝4600us；假设上下时长比例设定为1:3，那么下行数据时长＝4600*3/4＝3450us，上行数据时长＝1150us；AP根据不同终端设备的上/下行业务需求以及优先级分配得出的不同终端设备发送上/下行数据的具体时长，也可以简单的基于终端设备数目简单均分上下行数据时长给终端设备；例如在某个工作周期内，有终端设备STA1、STA2、STA3，根据他们的上/下行业务需求以 及优先级分配得出的各自发送上/下行数据的具体时长分别是：下行(1000us、450us、2000us)+上行(150us、400us、600us)，分配的这些时长完全可以用于终端设备的上下行数据发送，AP可根据上述时长为每一终端设备分配具体的时隙资源。为了保护不同终端设备在同一个方向上的数据发送不冲突，可以在不同终端设备上/下行数据发送间隔上预留第二指定长度和第三指定长度的保护间隔GP1/GP2，该时长也可以根据发送距离进行设定；例如设定GP1＝10us，GP2＝15us；于此同时，下行数据时长和上行数据时长之间也可以增加第一指定长度的保护间隔GP0，以防上下行数据冲突，例如设定GP0＝20us。
进一步地，广播信息时长、下行数据时长、上行数据时长以及竞争接入时长的分布位置确定的方法是：其中AP设定广播信息位置位于工作周期的初始位置，便于终端设备优先接收广播信息，获取上下行数据时长和竞争接入时长，例如发送该广播信息可以通过802.11中管理帧的Beacon帧发送；而下行数据时长、上行数据时长以及竞争接入时长的位置顺序则可以根据系统需求自行设定；例如，竞争接入时长可以位于下行数据时长和上行数据时长的中间，形成上下行数据发送的隔离，减少保护间隔开销。再例如竞争接入时长位于工作周期的末尾位置，支持ETSI认证时对预留时长的要求，如图2所示。
本实施例中，步骤S12中以确定的所述工作周期与所述各终端设备进行信息交互，并完成所述各终端设备无线网络的接入通过以下步骤实现，具体如下：
在所述广播信息时长的位置向覆盖范围内的各终端设备发送广播信息，所述广播信息包括当前接入点的标识号、竞争接入业务对应的竞争接入时长的分布位置、各个终端设备的标识号以及各个终端设备对应的上、下行时隙资源分配结果，以供覆盖范围内的终端设备根据所述广播信息在指定时间内进行当前接入点的竞争接入或者上行数据发送或者下行数据接收。
本实施例中，所有终端设备在每个工作周期开始优先接收广播信息获取竞争接入时长的位置以及对应的上、下行时隙资源分配结果，并在指定时间内进行竞争接入或者上行数据发送或者下行数据接收。具体的，所有终端设备在每个工作周期开始优先接收广播信息，获取本服务AP的标识号，确认是否与之关联或者可以关联的AP，若是则继续获取其他信息；否则，重新搜索其他广播信息；确认为与之关联或者可以关联的AP后，已接入的终端设备根据自己的标识获取与之对应的上行和下行的时隙资源，在自己对应的上行和下行的发送时长位置进行上行数据发送或者下行数据接收。未接入的终端设备仅获取竞争接入时长的位置。其中，与AP未关联的终端设备在竞争接入时长内发起竞争接入， 若竞争不成功，该终端设备退避等待下一个工作周期到来，接收广播信息获取下一个竞争接入时长位置再发起竞争接入。
本发明实施例，区分广播信息时长、上/下行数据时长和竞争接入时长，使得终端设备在指定时间内进行竞争接入或者上行数据发送或者下行数据接收，实现不同AP间上下行数据收发同步，减少上下行时长不同步所带来的交叉干扰；降低AP发送和接收的转换频率以及硬件处理复杂度，降低终端设备的功耗；
本发明实施例，AP集中分配广播信息发送、上/下行数据、竞争接入的时长和位置，提高资源利用率，减少竞争接入和正常上行数据发送的冲突碰撞，提高竞争接入的成功概率，减少已接入终端设备等待上行数据发送的时长，降低业务传输时延，提高终端设备业务质量和感知。

在实际应用中，若所述接入点不是当前终端设备已关联接入点或待关联接入点，则重新搜索其他接入点发送的广播信息，以查找可接入的接入点。
本实施例中，所有终端设备在每个工作周期开始优先接收广播信息获取竞争接入时长的位置以及对应的上、下行时隙资源分配结果，并在指定时间内进行竞争接入或者上行数据发送或者下行数据接收。具体的，所有终端设备在每个工作周期开始优先接收广播信息，获取本服务AP的标识号，确认是否与之关联或者可以关联的AP，若是则继续获取其他信息；否则，重新搜索其他广播信息；确认为与之关联或者可以关联的AP后，已接入的终端设备根据自己的标识获取与之对应的上行和下行的时隙资源，在自己对应的上行和下行的发送时长位置进行上行数据发送或者下行数据接收。未接入的终端设备仅获取竞争接入时长的位置。其中，与AP未关联的终端设备在竞争接入时长内发起竞争接入，若竞争不成功，该终端设备退避等待下一个工作周期到来，接收广播信息获取下一个竞争接入时长位置再发起。
