本发明实施例的技术方案应用于不同类型的无线局域网系统 (例如
NGiFi系统) , 且不同类型的无线局域网系统具有交叠的覆盖区域的场景 中。
其中, 本发明实施例的第一接入点设备与用户设备位于第一系统中, 第一系统为第一类型的无线局域网系统, 具体是指不具有基础设备的无线 局域网系统。 本发明实施例的网络设备、第二接入点设备和第三接入点设备位于第 二系统中, 第二系统为第二类型的无线局域网系统, 具体是指具有基础设 备的无线局域网系统;

101、 第一接入点设备从第二系统的接入点设备中选择一个作为所述 第一接入点设备附着的第二接入点设备。
由于第一接入点设备所属的第一系统没有其他基础设备 ( infrastructure ) , 当第一系统与第二系统具有交叠的覆盖区域、 且不 同步时,会造成第一系统与第二系统之间的交叉时隙干扰问题,也就是说, 第一系统的上行发送会干扰第二系统的下行接收, 或者第一系统的下行发 送会干扰第二系统的上行接收, 从而导致整个系统吞吐量的严重下降。
为了解决不同类型的无线局域网系统具有交叠的覆盖区域、 且不同步 时存在的交叉时隙干扰问题, 提高整个系统吞吐量, 本实施例中采用将第 一系统纳入到第二系统的管理之下, 因为第二系统具备完善的基础设备, 可 以通过第二系统的网络设备 (例如 AC ) 进行资源的协调与使用, 从而避免或 者消除了不同类型的无线局域网系统具有交叠的覆盖区域、 且不同步时存 在的交叉时隙干扰问题。

图 4为本发明另一实施例提供的无线传输控制方法的信令图, 图 5为 图 4所示无线传输控制方法应用的系统架构图, 如图 5所示, AP0 (相当于 第一接入点设备)和 STA0 (相当于用户设备) 构成一个 NGiFi系统, 简称 为第一系统, 属于第一类型的无线局域网系统, AP1、 AP2、 AP3、 AP4、 AP5、 APS以及他们服务的 STA构成另一个 NGiFi系统, 简称为第二系统, 属于 第二类型的无线局域网系统。 第一系统与第二系统具有交叠的覆盖区域、 且不同步, 例如图 5所示, 系统一位于系统二的覆盖之中。 如图 4所示, 本实施例的无线传输控制方法可以包括:
401、 AP0根据 AP0分别与 AP2、 AP5之间的信号质量、 信道利用率或 路损等信息确定 AP0附着的 AP2。
具体地, 由于 AP0所属的第一系统与 AP2、 AP5所属的第二系统具有交叠的 覆盖区域, APO在搜索网络时, AP0可能会搜索到 AP2、 AP5 ; APO可以根据 APO 与 AP2之间的信号质量或信道利用率等信息,和 AP0与 AP5之间的信号质量或信 道利用率等信息, 确定 AP0附着的 AP; 例如, AP0可以将信号质量好的 AP确定 为附着的 AP , 或者将信道利用率高的 AP确定为附着的 AP , 假设本实施例中, AP0将 AP2确定为 AP0附着的 AP (AP2相当于第二接入点设备)。
402、 AP0通过 AP2向 AC发送第一信息。
第一信息中包括 AP0分别与 AP2、 AP5之间的信号质量或信道利用率 等信道状态信息, 以及 AP0的带宽需求信息。
具体地, AP0同步接入 AP2 , 之后通过 AP2向 AC发送 AP0与 AP2之间 的信号质量或信道利用率等信道状态信息, AP0与 AP5之间的信号质量或 信道利用率等信道状态信息, 以及 AP0的带宽需求信息。
403、 STA0根据 STA0分别与 AP0、 AP2、 AP3与 AP5之间的信号质量、 信道利用率或路损等信息确定 STA0附着的 AP3。
例如, STA0与 AP2之间的信号质量最好时, STA0可以将 AP2确定为 STA0附着的 AP , 此时 AP0和 STA0附着的 AP是同一个 AP;
又例如, STA0与 AP3之间的信号质量最好时, STA0可以将 AP3确定为 STA0附着的 AP , 此时 AP0和 STA0附着的 AP不是同一个 AP。
404、 STA0通过 AP3向 AC发送第二信息。
假设本实施例中, STA0将 AP3确定为 STA0附着的 AP, STA0通过 AP3向 AC发 送第二信息。
其中, 第二信息中包括 STA0分别与 AP0、 AP2、 AP3与 AP5之间的信 号质量或信道利用率等信道状态信息, 以及 STA0的带宽需求信息。
405、 AC根据第一信息和第二信息, 确定 AP0和 STA0之间的传输模式 和传输带宽。
在实际应用中, AC在确定 AP0和 STA0之间的传输带宽时, 会考虑到网络 负荷状况, 例如 AC会考虑到 AP0、 AP2、 AP3和 AP5的网络负荷状况确定系统中 剩余带宽的大小; 然后, 根据第一信息中包括的 AP0分别与 AP2、 AP5之间的 信道质量信息, 以及 AP0的带宽需求信息, 第二信息中包括 STA0分别与 AP0、 AP2、 AP3与 AP5之间的信道质量信息, 以及 STA0的带宽需求信息, 若系统中剩 余带宽可以满足 AP0与 STA0的带宽需求, 则 AC根据 AP0的带宽需求信息和 STAO的带宽需求信息直接分配剩余带宽从而确定 APO和 STAO之间传输带宽; 否则, AC会按比例将剩余带宽给 AP0与 STAO从而确定 AP0和 STAO之间的传输 带宽。
本实施例中,假设 AC确定 AP0和 STAO之间传输带宽为 w, AP0在 AP2中占 用的带宽 w, 隔离带宽 w, AP0在 AP5中占用带宽 w, 隔离带宽 w ; STAO在 AP2中占用带宽 w, 隔离带宽 w, STAO在 AP5中占用带宽 w, 隔离带宽 w, STAO在 AP3中占用带宽 w, 隔离带宽 其中隔离带宽是由于两个系统如 果以频分的方式运行的时候, 必须有一定的隔离带, 否则会由于射频滤波 器的泄漏, 造成两个系统间的相互干扰;
根据公式 Ml=mcs/ (3 w + w + w + 计算直通模式时 ΑΡ0和 STAO之间的信 道质量与频谱效率的权衡因子; 其中 mc s为 AP0与 STAO直通模式时的调制编 码 ( modulation and coding scheme , mcs ) , (3 w + w' + w' + w" )是 APO禾口 STAO 传输数据需要耗费的系统带宽;
根据公式 M2= (mcs l+mcs2) /4W计算中继模式时 APO和 STAO之间的信道 质量与频谱效率的权衡因子, 其中, mc s l是中继模式时 AP0与 AP2之间调制 编码, mcs2中继模式时是 STAO与 AP3之间的调制编码;
如果 Ml大于 M2 , 则确定 AP0和 STAO之间使用直通模式, 若 Ml小于等于
M2 , 则确定 AP0和 STAO之间使用中继模式。
406、 AC将确定的 AP0和 STA0之间的传输模式和传输带宽, 通过 AP2发送 给 AP0。
407、 AC将确定的 AP0和 STAO之间的传输模式和传输带宽, 通过 AP3发送 给 STA0。
其中, 步骤 406和步骤 407可以并行执行。
408、 AP0与 STA0根据 AC发送的传输模式和传输带宽进行数据传输。 图 6为图 4所示实施例中 AP0和 STA0之间的直通模式和中继模式的 传输示意图, 如图 6所示:
当 AP0和 STA0之间的传输模式为直通模式时, AP0和 STA0之间直接 进行数据传输;
当 AP0和 STA0之间的传输模式为中继模式时, AP0和 STA0分别通过 各自附着的 AP ( AP2和 AP3 ) 进行数据传输, 例如, 当 AP0发送下行数据 给 STAO时, 具体地, APO将发送给 STAO的下行数据发送给 AP2, AP2将发 送给 STAO的下行数据发送给 AP3, AP3将该下行数据发送给 STAO ;当 STAO 发送上行数据给 AP0时, 具体地, STAO将发送给 AP0 的上行数据发送给 AP3, AP3将发送给 AP0的上行数据发送给 AP2, AP2将该上行数据发送给 AP0。
本发明实施例中, 当 AP0和 STAO所属的第一系统与其他 AP所属的第 二系统为不同类型的无线局域网系统、且具有交叠的覆盖区域、不同步时, 为了存在的交叉时隙干扰问题, AC根据 AP0通过其同步接入的 AP2发送的 第一信息, 以及 STAO通过其同步接入的 AP3发送的第二信息, 确定当 AP0 和 STAO之间的传输模式和传输带宽, 并将确定的传输模式和传输带宽分 别发送给 AP0和 STAO , 以使 AP0和 STAO利用网络设备确定的传输模式和 传输带宽进行数据传输; 提高了系统共存时的网络资源利用效率和系统吞 吐量。
