Description

用于无线分布***的接入方法、 ***及无线中继器 技术领域 本发明涉及通信领域, 尤其涉及一种用于无线分布*** (Wireless Distribution System, WDS ) 的接入方法、 ***及无线中继器。 背景技术 无线局域网作为网络终端的一种接入技术, 具备接入速度高, 布线简易 等优点, 已被广泛地应用。 在某些复杂的使用环境, 如一位用户在两层住宅 中使用无线路由器, 路由器放在一楼, 楼上一些房间信号不强; 再如一位用 户希望跟对门的邻居共享宽带, 无奈中间障碍重重不便布线, 用笔记本连接 邻居的无线网络掉线频繁等场景, 就可以用 2个支持 WDS的无线中继的设 备来延伸无线覆盖范围, 解决在复杂使用环境中的网络使用问题。 通常将上述两个支持 WDS功能的无线设备中的一个称为无线接入点, 简称 AP, 另一个称为无线中继器, 简称 Repeater。 无线接入点通过所支持的 宽带接入技术, 如 xDSL、 xPON、 3G等宽带接入技术, 接入 Internet, 无线 中继器通过 WDS 与无线接入点进行无线中继, 将无线中继器用户访问 Internet的 4艮文通过桥接经 WDS无线接口转发到无线接入点, 无线接入点再 将该用户 4艮文发送到 Internet; 无线接入点还将从 Internet回应该用户的 4艮文 经 WDS 无线接口转发到无线中继器, 无线中继器再通过桥接将 4艮文发送到 该用户。 在相关技术中的用于 WDS的接入***中, 无线中继器仅用于在无线接 入点 AP和用户之间转发 4艮文, 而由 AP来执行路由的分配, 由于 AP可分配 的路由地址有限, 使得可接入到多个无线中继器的总用户数量受限于该 AP 的可分配路由地址数量, 在接入的用户数增加时, 需要增加 AP, 由于 AP位 于***网络侧, 不便于配置。 发明内容 本发明的目的在于提供一种用于无线分布***的接入方法、***及无线 中继器, 能够解决相关技术中在接入的用户数增加时, 需要增加 AP, 不便 于配置的技术问题。 根据本发明的一个方面, 提供了一种用于无线分布***的无线中继器, 包括: 拨号模块, 用于为无线中继器获取 IP地址; 路由转发模块, 用于使用 IP地址转发在因特网和用户设备之间传输的数据。 优选地, 拨号模块包括: 发送单元, 用于向因特网发送请求, 其中携带 无线中继器的标识; 接收单元, 用于接收分配的 IP地址; 配置单元, 用于将 接收到的 IP地址设置为无线中继器的 IP地址。 优选地, 无线中继器还包括: 无线分布***接口模块, 用于执行与无线 分布***的无线接入点的无线中继; 用户接口模块, 用于接入用户设备。 优选地, 所述数据包括单播数据、 组播数据、 和广播数据。 优选地, 所述数据是单播数据, 所述路由转发模块根据所述 IP地址转 发在因特网和用户设备之间传输的数据。 根据本发明的另一个方面, 还提供了一种用于无线分布***的接入系 统, 包括: 无线接入点、 无线中继器, 无线中继器包括: 拨号模块, 用于为 无线中继器获取 IP地址; 路由转发模块, 用于使用 IP地址转发在因特网和 用户设备之间传输的数据。 优选地, 拨号模块包括: 发送单元, 用于向因特网发送请求, 其中携带 无线中继器的标识; 接收单元, 用于接收分配的 IP地址; 配置单元, 用于将 接收到的 IP地址设置为无线中继器的 IP地址。 优选地, 无线中继器还包括: 无线分布***接口模块, 用于执行与无线 分布***的无线接入点的无线中继; 用户接口模块, 用于接入用户设备。 优选地, 无线接入点包括: 转发模块, 用于转发在因特网和无线中继器 之间传输的数据。 优选地, 所述数据包括单播数据、 组播数据、 和广播数据。 优选地, 所述数据是单播数据, 所述路由转发模块根据所述 IP地址转 发在因特网和用户设备之间传输的数据。 根据本发明的又一个方面, 还提供了一种用于无线分布***的接入方 法, 包括: 为无线中继器获取 IP地址; 才艮据 IP地址将无线中继器经无线接 入点接入因特网。 优选地, 为无线中继器获取 IP地址具体包括: 无线中继器通过 PPPoE 或 IPoE拨号方式获取访问因特网的 IP地址。 优选地,根据 IP地址将无线中继器经无线接入点接入因特网具体包括: 在无线中继器和无线接入点之间建立无线中继;将无线接入点连接到因特网; 用户设备发送访问因特网报文到无线中继器, 无线中继器将报文路由转发到 无线接入点; 无线接入点将报文发送到因特网; 因特网根据报文返回对应的 应答消息, 并将应答消息发送给无线接入点; 无线接入点将应答消息发送给 无线中继器; 无线中继器对应答消息路由转发给用户设备。 借助于本发明的上述至少一个技术方案,通过利用拨号模块为无线中继 器获取 IP地址, 使得无线中继器具备路由转发功能, 从而在接入***的用户 数较大时,可以通过增加用户侧的无线中继器来增加***可接入用户的数量, 而不需要增加 AP, 所以避免了在接入的用户数增加时, 需要增加 AP, 不便 于配置的技术问题, 达到能够方便地增加可接入用户的技术效果。 附图说明 附图用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与本 发明的实施例一起用于解释本发明, 并不构成对本发明的限制。 在附图中: 图 1是 居本发明第一实施例的无线中继器的方框图; 图 2 是根据本发明第二实施例的用于无线分布***的接入***的方框 图; 图 3 是根据本发明第三实施例的用于无线分布***的接入方法的流程 图; 图 4 是根据本发明第四实施例的用于无线分布***的接入方法的流程 图。 具体实施方式 以下结合附图对本发明的优选实施例进行说明, 应当理解, 此处所描述 的优选实施例仅用于说明和解释本发明, 并不用于限定本发明。 在以下的描述中, 为了解释的目的, 描述了多个特定的细节, 以提供对 本发明的透彻理解。 然而, 艮显然, 在没有这些特定细节的情况下, 也可以 实现本发明, 此外, 在不冲突的情况下, 即在不背离所附权利要求阐明的精 神和范围的情况下,下述实施例以及实施例中的各个细节可以进行各种组合。 第一实施例 图 1是 居本发明第一实施例的无线中继器的方框图。 如图 1所示, 根据本发明第一实施例的无线中继器 100包括: 拨号模块 110, 用于为无线中继器获取 IP地址; 路由转发模块 108, 用于使用 IP地址 转发在因特网和用户设备之间传输的数据。 根据本发明第一实施例的无线中继器通过利用拨号模块来为无线中继 器获取路由地址, 使得在接入***的用户数较大时, 可以通过增加用户侧的 无线中继器来增加***可接入用户的数量, 而不需要增加 AP, 所以避免了 在接入的用户数增加时, 需要增加 AP, 不便于配置的技术问题, 达到能够 方便地增加可接入用户的技术效果。 例如, 在相关技术中, AP的可分配路由地址为 255个, 则通过 N个无 线中继器接入该 AP 的用户数最大为 255 , 而在 居本发明第一实施例的用 于无线分布***的接入***中, 通过 N个无线中继器接入该 AP的用户数将 达到 N*255。 并且, 在用户数增大时, 只需要增加无线中继器的数量就可实 现增加接入用户的目的。 另外,根据本发明第一实施例的无线中继器降低了通过无线中继器接入 的用户对无线接入点的功能要求, 当用户釆用路由模式接入 Internet 时, 由 于路由模式已经在无线中继器上实现, 所以无线接入点无需再为无线中继器 的用户提供路由方式接入, 使组网和应用更加灵活。 另外,才艮据本发明第一实施例的无线中继器还可以简化对无线接入点和 无线中继器的功能要求和接口要求, 从而达到降低成本的目的。 无线接入点 上行提供宽带接入技术, 如 xDSL、 xPON、 3G等接入技术, 下行提供 WDS 无线中继和用户接入, 桥接转发用户访问 Internet 的 4艮文; 无线中继上行只 提供 WDS无线中继, 下行提供用户接入, 桥接或路由转发用户的报文, 即, 根据本发明第一实施例的用于无线分布***的接入***中的 AP只需要实现 数据的转发和协议的转换功能, 从而达到简化设备形态, 降低设备整体成本 的技术效果。 优选地, 拨号模块包括: 发送单元, 用于向因特网发送请求, 其中携带 无线中继器的标识; 接收单元, 用于接收分配的 IP地址; 配置单元, 用于将 接收到的 IP地址设置为无线中继器的 IP地址。 无线中继设备上支持路由模块, 以及拨号模块, 如 PPPoE、 IPoE等拨 号模块, 无线中继设备与无线接入点设备 WDS连接成功后, 无线中继设备 发起拨号,经 WDS无线接口以及通过无线接入点设备获取访问 Internet的 IP 地址。 无线中继设备用户的报文, 经无线中继设备路由模块转发, 经 WDS 无线接口发送到无线接入点设备, 进而访问 Internet, 优选地, 无线中继器还包括: WDS接口模块 104, 用于执行与无线分 布***的无线接入点的无线中继; 用户接口模块 106, 用于接入用户设备。
