WiMAX无线网络接口和 WiFi局域网络接口; 其中, 所述 CPE的上行接口为 WiMAX接口, 与 WiMAX无线网络的基站通信, 下行接口为 WiFi接口, 与 移动终端的 WiFi接口进行局域通信。所述 CPE和所述移动终端实际上也可以 通过其它接口进行通信, 例如当所述移动终端具有一个 WiMAX无线接口时, 还可以具有一个 3GPP无线接口与所述 CPE的 3GPP微微基站( Femtocell )下 行接口通信。 所述 CPE和所述移动终端也可以通过蓝牙或有线的以太接口通 信等等。 所述 CPE可以是一个单一的物理设备, 也可以是分离的至少两个物 理设备。 当所述 CPE是分离设备时, 一部分为 CPE主体, 该部分包含所述的 WiMAX接口, 负责与 WiMAX基站通信; 另一部为 CPE的拉远连接模块; 该 部分包含所述 WiFi接口, 负责与移动终端通信。 所述 CPE的两个部分之间可 以采用以太网等方式连接, 此时所述的 CPE的两个部分之间通信视为 CPE内 部通信, 有关所述 CPE内部通信此处不再赘述。 实施例一
当所述移动终端从室外移动到室内,如果所述移动终端在室外所附着基站 与室内 CPE所附着基站相同, 则本发明实施例提供的一种天线通信方法流程 如图 3所示, 其具体流程如下:设移动终端原来直接通过 WiMAX接口附着到 BS , 并正在使用业务, 现在移动终端移动到室内。
301 : 移动终端的 WiFi接口接收所述 CPE下行无线接口发送的信息帧, 所述信息帧中携带有 CPE上行接口即 WiMAX接口连接的 WiMAX无线网络 信息, 所述 WiMAX无线网络信息包括 WiMAX无线网络的标识以及 CPE所 附着的 WiMAX无线网络的 BS的标识。 其中, 所述信息帧可以为通过 CPE 的 WiFi接口周期性广播的 WiFi信标帧 (beacon ), 所述 WiFi信标帧中包含 WiMAX无线网络标识信息、 以及 CPE所附着的 WiMAX基站的标识即 BSID 等。
需要说明的是, 所述移动终端可以一直同时打开两个无线接口; 其中, WiMAX接口正在通信, 而 WiFi接口扫描 CPE的 WiFi接入点。 为了省电, 移动 终端也可以在使用 WiMAX接口正常通信时关闭 WiFi接口, 仅在发现 WiM AX 接口信号较弱时才打开其 WiFi接口。
还值得说明的是, 所述移动终端也可以主动发送 WiFi探测请求帧 (Probe Request )给 CPE, 所述探测请求帧也采用广播方式, 并可以在探测请求帧中指 示希望发现的 CPE的属性信息, 例如: CPE类型; CPE收到这样的探测请求帧 后, 如果所述 CPE的属性与所述探测请求帧所指示的 CPE属性信息相匹配, 则 所述 CPE发送探测响应帧给所述移动终端, 所述探测响应帧中包含 WiM AX无 线网络标识和 BSID信息等。 所述 WiMAX无线网络标识可以用来表明 CPE所连 接的 WiM AX无线网络是否和移动终端所连接的 WiM AX无线网络为同一网络。
302: 移动终端发现要找的 CPE之后, 与所述 CPE建立局域网连接即 WiFi 连接。 具体地讲, 就是如果所述移动终端根据所述信息帧(例如: WiFi信标帧 或探测响应帧)发现与其处于同一个 WiMAX无线网络的 CPE (通过对比网络 标识), 且 CPE所附着的基站和所述移动终端所附着的基站相同 (通过比对基 站标识),则所述移动终端与所述 CPE建立连接。其具体的连接过程可参考 IEEE 802.11标准, 本发明不再详细描述。 所谓移动终端要找的 CPE具有以下特点: 所述 CPE的上行接口是 WiMAX接口, 并且与移动终端连接到相同的
WiM AX无线网络, 并且 CPE所附着的基站与移动终端所附着的基站相同。
需要说明的是, 所述移动终端通过 WiFi接口连接到 CPE的过程中, CPE可 能还需要对所述移动终端进行认证, 例如: 如果 CPE是移动终端用户家庭内部 的设备,则用户可以自己配置 CPE的 WiFi接口与移动终端 WiFi接口认证所使用 的帐号、 密钥等信息; 如果 CPE是公共场合的热点设备, 则移动终端可以通过 其它途径获得可以连接该 CPE的 WiFi帐号和密钥等信息, 如与 WiMAX帐号信 息一同进行预配置。所述认证过程与现有技术中的认证过程相同,此处不再赘 述。 按照 WiFi规范, CPE也可以不对移动终端进行认证, 即总是允许移动终端 接入。
303: CPE为所述移动终端分配 IP地址, 并将其为所述移动终端分配的 IP 地址以及 CPE的 IP地址发送给所述移动终端。 该步骤的具体实现过程如下: SI : CPE接收所述移动终端的地址分配请求;
S2: CPE为所述移动终端分配一个私网 IP地址;
S3: CPE将其自身的 IP地址以及所述私网 IP地址发送给所述移动终端。 此处 CPE可视为是 LAN (Local Area Network , 局域网 W WiM AX无线网络 之间的网关设备。 所述 CPE自身的 IP地址是 CPE的下行接口呈现的 IP地址, 也 就是说是 LAN侧的 IP地址。 其中, CPE的 WAN ( Wide Area Network , 广域网) 侧是 WiM ΑΧ接口, LAN侧是 WiFi接口, 两侧可以使用不同的 IP地址。 WAN侧 使用从 WiM AX无线网络获得的公网 IP地址, 而 LAN侧则可以使用一个事先定 义好的私网 IP地址。 当然, CPE也可以在 WiFi接口使用 WAN侧获得的公网 IP 地址。
移动终端请求 IP地址的过程通常使用 DHCP协议完成, 正如上述步骤 S 1、 S2、 S3所述, 此处不再详细描述。 移动终端请求 IP地址的过程也可以使用其它 方式, 例如自动选择, 即移动终端随机选择一个 IP地址, 然后检测所选中的 IP 地址是否已被所在局域网络中的其它设备使用, 若已被其它设备使用, 则重新 随机选择一个地址, 直到选中一个可用的 IP地址。 移动终端也可以从所述驻地 设备广播的可用 IP地址池中选择一个 IP地址, 然后将选中的 IP地址通知驻地设 员理应知道各种 IP地址分配方法, 这里不——详细说明。
需要说明的是, 所述步骤 303是用于所述移动终端与 CPE之间建立 IP隧道 所用, 为可选步骤。
304: 移动终端与 CPE建立通信隧道。 所述建立的隧道可以为 IP隧道或者 还可以是 MAC层隧道; 例如: 当移动终端与 CPE建立 IP隧道时, 所述隧道的一 端为移动终端侧, 地址为 CPE为所述移动终端分配的私网 IP地址; 所述隧道的 另一端为 CPE侧, 地址为 CPE的 IP地址。 所述 IP隧道可以 IPsec ( IP安全封装) 隧道, 也可以是 GRE ( Generic Routing Encapsulation, 通用路由封装) 隧道, 也可以是其它形式的隧道, 所述 IP隧道用于传输所述移动终端与 WiMAX无线 网络基站之间的 WiMAX空口 MAC帧。 当移动终端与 CPE之间建立 MAC层隧道 时, 所述移动终端与 WiMAX无线网络基站之间的 WiMAX空口 MAC帧将作为 WiFi MAC帧的数据传递。
305: 移动终端向 CPE发送共享天线请求消息; 所述共享天线请求消息中 包含所述移动终端在其所附着基站上的所有 WiMAX空口连接标识以及连接的 属性信息。 其中, 所述连接的属性信息用于区分所述连接是专用于上行帧还是 专用于下行帧; 或者, 所述连接可以同时用于上行帧和下行帧, 即双向连接; 所述连接的属性信息还可以包含所述连接的 QoS参数, 以便所述 CPE在所述移 动终端和所述基站之间转发所述终端与所述基站之间的空口 MAC帧时按照各 个所述空口连接的 QoS参数进行调度。
需要注意的是,移动终端也可以同时将自己的终端标识发送给 CPE。其中, 所述终端标识可以是移动终端的 WiMAX接口 MAC地址, 或在建立通信隧道时 获得的由 CPE分配的隧道标识、 也可以直接使用所获得的私网 IP地址等, 只要 对于 CPE来说能识别连接所属的移动终端即可。 移动终端也可以不用专门向 CPE发送自己的标识, CPE可以从收到的请求消息中获得移动终端的 IP地址或 WiFi MAC地址作为移动终端的标识。
还需要说明的是, 所述共享天线请求消息可以在已建立的隧道中传输, 也 可以在 IP层定义一个接口, 通过 IP层接口传递移动终端的 WiMAX空口连接信 息, 也可以在 WiFi的管理帧中定义一个数据元素和 /或消息类型, 通过 WiFi管 理帧传递移动终端的 WiMAX空口连接信息。 具体传递方法本发明不作限制。 当通过隧道传递移动终端的 WiMAX空口连接信息时, 可以增加一个指示信息 表示所传递的信息是 WiMAX空口 MAC帧还是另外定义的信令消息。
306: CPE接收到移动终端的共享天线请求后, 根据所述连接的属性信息 为所述移动终端的每个连接建立緩存队列,根据所述连接的属性, 所建立的对 应的緩存队列属于上行緩存队列或下行緩存队列。对于双向的连接,应分别建 立上行队列和下行队列。 所述上行緩存队列用于緩存所述移动终端向基站 BS 发送的上行帧, 所述下行队列用于緩存从 BS接收到的待转发给所述移动终端 的下行帧。
需要注意的是, 因为 CPE是根据所述移动终端发送的连接以及其属性信息 来建立緩存队列,所以当所述移动终端通知离开 CPE或发现所述移动终端不再 与所述 CPE连接时, 所述 CPE应该删除与所述移动终端的相关的緩存队列。
还需要注意的是, CPE还可以给移动终端回一个响应消息以示收到移动终 端的共享天线请求消息。如果 CPE受资源限制等原因无法将天线共享给移动终 端时, CPE在响应消息中指示拒绝该请求。
还需要注意的是, 所述移动终端也可以在先向 CPE发出一个查询请求, 然 后, 根据 CPE的响应, 再向 CPE发送携带有所述连接以及其属性信息的共享天 线请求。
在完成上述步骤 306之后,移动终端就可以通过 CPE与 WiMAX无线网络基 站进行数据交互。 所述移动终端通过 CPE与基站进行数据交互的过程如下:
307: 移动终端发送上行 WiMAX空口 MAC帧给 CPE。
由于移动终端是连接到 CPE的, 而不是直接连到 BS, 因此移动终端在有待 发送的 WiMAX空口 MAC帧时就立即发送给 CPE, 而不用等待 WiMAX空口发 送机会窗。 事实上由于移动终端不能很好地接收 BS的信号, 它也不知道自己 的发送机会窗。
移动终端将要发送的 WiMAX空口 MAC帧封装到前述步骤描述的与 CPE 之间的隧道中传递。 具体地讲, 如果移动终端和 CPE之间建立了 IP隧道, 则移 动终端将 WiMAX空口 MAC封装到 IP^艮文中, 所述 IP^艮文的源地址是移动终端 从 CPE获得的私网 IP地址, 目的地址是 CPE的 IP地址。 在所述 IP报文的头部指 示这是一个隧道报文, 其中封装的数据类型是 WiMAX空口 MAC帧。 完成封装 后, 通过 WiFi接口将所述 IP隧道报文发送给 CPE。
如果移动终端和 CPE之间建立了二层隧道, 即 WiFi的 MAC层隧道, 则移 动终端直接将 WiMAX空口 MAC帧作为数据封装在 WiFi数据 MAC帧中 ( WiFi 的 MAC帧分数据帧、 管理帧、 控制帧), 并在帧头指示这是隧道帧, 其中封装 的数据是 WiMAX空口 MAC帧。
308: CPE将移动终端的上行 WiMAX空口 MAC帧放入上行緩存队列。 移动终端上所有上行的 WiMAX空口 MAC帧必须在 BS安排的时间点发射, 因此 CPE收到移动终端的 WiMAX空口 MAC帧之后并不能立即就发射, 所以 CPE先将它们放入所述 WiMAX空口 MAC帧所属的连接对应的队列中。 所述 WiMAX空口 MAC帧头有连接标识。 CPE自己产生的待发送 WiMAX空口 MAC 帧也是同样处理, 也要先放入 CPE的各连接緩存队列中。 因此, CPE完全可以 将移动终端的连接看成是自己的连接, 只不过相关的 WiMAX空口 MAC帧是移 动终端产生并送过来的, 而不是 CPE自己产生的。
由于一个 BS给不同的 WiMAX终端 (包括这里所说的移动终端和 CPE )分 配的连接标识不会重复, 因此 CPE可以筒单地从移动终端的 WiMAX空口 MAC 帧的头部取出连接标识,然后将 WiMAX空口 MAC帧放到与从 MAC帧头取出的 连接标识相应的待发送队列。
309: CPE侦听 BS的下行映射表和上行映射表。
WiMAX基站在每一个物理帧的开始处安排一些广播信息, 其中包含 DLMAP (下行映射表 )和 ULMAP (上行映射表 )。 在 DLMAP中指示各下行空 口连接的标识以及各下行连接的 WiMAX空口 MAC帧出现的开始时间点, 而 ULMAP中指示了各上行空口连接以及各上行连接可以在什么时间点发送 WiMAX空口 MAC帧以及可以发送多长时间。在广播信息之后就是下行子帧和 上行子帧 (物理帧), WiMAX终端可以根据 DLMAP中的信息在下行子帧指定 的时间点接收某个连接的 WiMAX空口 MAC帧, 以及在上行子帧指定的时间点 发射某个连接的 MAC帧。
310: CPE接收基站发送的下行帧。
需要说明的是, 对于上下行时分的系统, WiMAX基站的下行子帧出现在 上行子帧之前, 而对于上下行频分的系统则上下行子帧是同时进行的。 CPE解 析 DLMAP之后, 就在指定的时间点接收自己的和请求了共享天线的移动终端 的各连接的 MAC帧。
311 : CPE收到 WiMAX空口 MAC帧之后,才艮据帧头的连接标识将其放入对 应的下行緩存队列。这些下行緩存队列有的是 CPE自己的,有的是移动终端的, 但 CPE这时不需要区分哪个是自己的, 哪个是移动终端的。
312: CPE向基站发送上行帧。
CPE在所述 BS的上行子帧期间, 按照从 ULMAP中获得的连接发送时间窗 信息, 从所述上行连接緩存队列中取出待发送的 MAC帧发送, 所述连接的发 送时间窗是指 ULMAP中指定的连接开始发送时间和持续时长。 所述上行连接 緩存队列包括 CPE自身的上行连接緩存队列和所述移动终端的上行连接緩存 队列。 CPE自身的连接緩存队列中的 MAC帧是 CPE自己产生的, 而所述移动终 端的连接緩存队列中的 MAC帧是在步骤 307从移动终端那里接收到的。 CPE这 个时候其实不需要区分哪个队列是自己的,哪个是移动终端的, 只需要从各上 行緩存队列中取出待发送的 MAC帧发送, 并满足各连接的 QoS要求。
313: CPE将移动终端下行连接緩存队列中的 WiMAX空口 MAC帧转发给 移动终端。
CPE处理各下行緩存队列中緩存的 MAC帧时,如果移动终端的下行连接緩 存队列中存在待处理的 WiMAX空口 MAC帧, CPE就通过 WiFi接口转发给移动 终端。 CPE可以 4艮据连接标识对应的终端标识信息找到对应的隧道, 将所述下 行緩存队列中的 WiMAX空口 MAC帧封装在此隧道中传递到移动终端。如果所 述隧道是 IP隧道, 则所封装的 ΙΡ·^艮文的源地址是 CPE自己的 IP地址, 而目的地 址是 CPE所分配给该移动终端的私网 IP地址。
上述过程 307到 313实际上包含了两个相互独立的过程,其中 307、308、309、 312完成了移动终端向 BS发送 WiMAX空口 MAC帧的过程, 而 309、 310、 311、 313完成了移动终端从 BS接收 WiMAX空口 MAC帧的过程。
实施例二
在 WiMAX规范中,从应用的角度讲业务流是一个具体的会话过程, 例如: 一次语音通话过程中的呼叫信令业务流和通话建立后的语音业务流。在所述业 务流的建立过程中,基站将为每个业务流分配一个连接标识, 以便在传输时对 每个业务流作不同的处理,满足其 QoS要求。由于所述业务流不是固定不变的, 所以移动终端所拥有的连接标识也不是固定不变的。移动终端应该即时将连接 的变化情况告知 CPE, 以便 CPE建立新的连接緩存队列或删除连接緩存队列。 图 4是移动终端请求建立一个业务流之后向 CPE更新连接信息的过程, 具 体步骤描述如下:
401 : 移动终端向 CPE发送添加业务流请求消息, 这个消息具体来说是 DSA-REQ, 移动终端将所述消息通过 WiFi接口的隧道传递给 CPE。
402: CPE将所述请求消息放入对应的上行緩存队列中。 由于所述动态服 务添加请求消息 DSA-REQ属于 WiMAX空口的管理消息,所以所述动态服务添 加请求消息 DSA-REQ需要緩存在对应的管理连接緩存队列。
403: CPE侦听 BS广播帧信息, 获得 DLMAP和 ULMAP。 因为移动终端已 经将其管理连接信息发送给了 CPE, 并建立对应的緩存队列, 所以 CPE会从 ULMAP中检查移动终端的管理连接的发送时间窗。
404: CPE在上行物理子帧中发送移动终端的请求消息。 CPE获得移动终 端管理连接的发送时间窗后,就在指定时间从移动终端管理连接对应的上行队 列中取出待发送的消息发送出去。在本例中也就是将移动终端的动态服务添加 请求消息 DSA-REQ发送出去了。 可以理解的是, 如果在动态服务添加请求消 息之前,移动终端管理连接上行队列中还有其它管理消息待发送, 所述动态服 务添加请求消息未必能在紧接而来的物理帧周期中发送出去,可能会等待下一 个物理帧周期才能发送出去。
405: CPE继续侦听 BS广播信息, 解析新的 DLM AP和 ULM AP。
406: CPE从 DLMAP中发现移动终端管理连接有下行帧, 就在指定时间点 从下行物理子帧中接收移动终端管理消息。对于本例来说, 就是接收携带有所 述请求的响应消息的下行帧。 407: CPE将接收到的下行管理消息即所说响应消息放到移动终端管理连 接的下行緩存队列。
408: CPE从移动终端管理连接的下行队列中取出所述响应消息通过隧道 发送给移动终端。
409: 移动终端从响应消息中解析出所述连接信息为其新业务流的连接标 识。
410: 移动终端向 CPE发送共享天线请求消息, 将所述新业务流的连接或 者全部连接信息放在共享天线请求消息中发送给 CPE。
411 : CPE收到移动终端的共享天线请求消息后, 为移动终端新的连接建 立对应緩存队列。
需要说明的是,如果移动终端总是在共享天线请求消息中携带移动终端所 有的连接信息, 则 CPE可以检查已经为移动终端建立的连接緩存队列和请求消 息中的连接是否匹配;如果已经建立的连接緩存队列的连接在新的请求消息中 未包含, 意味着该连接已经删除, 则 CPE删除该连接对应的队列。
需要说明的是, 以上过程的关键是步骤 410和 411 , 即移动终端的连接信息 变化时, 要即时告知 CPE。 实际上移动终端上连接的变化情况还有多种, 例如 基站主动通知移动终端建立新的业务流, 由此而产生新的连接。
还需要说明的是, 移动终端或基站都可以删除移动终端的一个业务流, 则 相应的连接也删除, 当移动终端进入 WiMAX空闲模式时, 一些暂时不用的连 接也应该删除。移动终端可以用天线共享请求消息携带全部在用连接信息的方 式或者专门定义一个删除指定连接的请求消息通知 CPE某个连接已删除,这些 过程本领域技术人员都可以筒单地推理得到其解决方法, 这里不再详细描述。 实施例三
当所述移动终端从室外移动到室内, 如果 CPE附着的基站和移动终端附 着的基站不同,但它们确属于同一个 WiMAX无线网络, 则移动终端可以在连 接到 CPE的 WiFi接口之前,先在 WiMAX空口上完成向 CPE所附着的 WiMAX 基站切换, 之后再与 CPE建立 WiFi连接。 但是有可能移动终端未完成这种基 站切换就失去了 WiMAX信号, 此时所述移动终端共享室内 CPE的天线通信 方法流程如图 5所示。 另外, 当所述移动终端在室内开机, 也可以按照图 5 所示流程通过所述 CPE完成向 WiMAX无线网络初始入网过程。 图 5具体流 程如下:
501 : 移动终端的 WiFi接口接收所述 CPE的 WiFi接口发送的信息帧, 所述 信息帧中携带有 WiM AX无线网络信息; 所述 WiM AX无线网络信息包括
WiMAX无线网络标识以及 CPE所附着的 WiMAX BS的标识等。 所述移动终端 根据所述信息帧中携带的信息可以判断所述 CPE所连接的 WiMAX无线网络与 移动终端所连接的 WiMAX无线网络相同, 但 CPE附着的基站和移动终端附着 的基站不同, 或者所述 CPE所连接的 WiMAX无线网络与移动终端希望连接的 WiMAX无线网络相同, 但所述移动终端未进入 CPE所连接的 WiMAX无线网 络。
502: 移动终端发现要找的 CPE之后, 与所述 CPE建立连接即 WiFi连接。 其具体的连接过程可参考 IEEE 802.11标准, 本发明不再详细描述。
503: CPE为所述移动终端分配 IP地址, 并将其为所述移动终端分配的 IP 地址以及 CPE的 IP地址发送给所述移动终端。 该步骤的一种具体实现过程如 下: SI : CPE接收所述移动终端的地址分配请求;
S2: CPE为所述移动终端分配一个私网 IP地址;
S3: CPE将其自身的 IP地址以及所述私网 IP地址发送给所述移动终端。 此处 CPE可视为是 LAN (Local Area Network , 局域网 W WiM AX无线网络 之间的网关设备。 所述 CPE自身的 IP地址是 CPE的下行接口呈现的 IP地址, 也 就是说是 LAN侧的 IP地址。 其中, CPE的 WAN ( Wide Area Network , 广域网) 侧是 WiM ΑΧ接口, LAN侧是 WiFi接口, 两侧可以使用不同的 IP地址。 WAN侧 使用从 WiM AX无线网络获得的公网 IP地址, 而 LAN侧则可以使用一个事先定 义好的私网 IP地址。 当然, CPE也可以在 WiFi接口使用 WAN侧获得的公网 IP 地址。
移动终端请求 IP地址的过程通常使用 DHCP协议完成,此处不再详细描述。 需要说明的是, 所述步骤 503是用于所述移动终端与 CPE之间建立 IP隧道 所用, 为可选步骤。
504: 移动终端与 CPE建立通信隧道。 所述建立的隧道可以为 IP隧道或者 还可以是 MAC层隧道; 例如: 当移动终端与 CPE建立 IP隧道时, 所述隧道的一 端为移动终端侧, 地址为 CPE为所述移动终端分配的私网 IP地址; 所述隧道的 另一端为 CPE侧, 地址为 CPE的 IP地址。 所述所说 IP隧道可以 IPsec ( IP安全封 装) 隧道, 也可以是 GRE ( Generic Routing Encapsulation, 通用路由封装) 隧 道, 也可以是其它形式的隧道, 所述 IP隧道用于传输所述移动终端与 WiMAX 无线网络基站之间的 WiMAX空口 MAC帧。 当移动终端与 CPE之间建立 WiFi的 MAC层隧道时, 所述移动终端与 WiMAX网络基站之间的 WiMAX空口 MAC帧 将作为 WiFi MAC帧的数据传递。 505: 移动终端向 CPE发送共享天线请求消息; 由于所述移动终端还没有 获得 CPE附着基站给其终端分配的连接,所以所述共享天线请求消息中的连接 列表仅包含 WiMAX规范定义的初始测距空口连接标识, 也可以不带任何连接 信息。
506: CPE收到共享天线请求消息后, 如果所述共享天线请求消息中仅携 带有初始测距空口连接标识, 或没有连接信息, 则 CPE为该终端建立初始测距 空口连接标识的緩存队列。
需要说明的是,如果共享天线请求消息中连接信息列表为空用来表示通知 CPE删除该终端相关的所有连接緩存队列,则此步骤必须在请求消息中携带初 始测距空口连接信息。
步骤 505和 506所述的消息可以通过所述隧道传输,也可以不在所述隧道中 传输。 本实施例中步骤 505和 506不是必须的。
507: CPE接收所述移动终端通过隧道发送的冲突测距请求消息, 并将所 述冲突测距请求消息緩存到对应的连接緩存队列; 其中, 所述冲突测距请求消 息按照 WiMAX规范必须携带移动终端原来附着的基站的 BSID信息, 并指示测 距的目的是切换基站, 或者所述冲突测距请求消息指示测距的目的是初始入 网, 此时不需要携带所附着基站的 BSID信息, 因此终端还没有附着到某个基 站。 因为是冲突测距请求消息是基于竟争的测距, 所以该请求消息中还必须携 带移动终端的 WiMAX MAC地址信息, 同时 MAC帧头部的连接标识是初始测 距空口连接标识。 所谓基于竟争就是说这样的测距请求将在上行竟争期发送。 上行竟争期是上行物理子帧开始的那段时间,尚未获得有效连接标识的终端在 这个期间通过竟争的方式发送初始的测距请求。 不过,移动终端是将这个请求 消息通过 WiFi接口的隧道发送给 CPE,移动终端不用管 WiMAX接口的竟争期。 CPE收到这样的 WiMAX空口 MAC帧后, 与一般的 WiMAX空口 MAC帧处理方 式一样, 即按照帧头的连接标识将其放入相应的待发送上行队列, 只不过对于 初始测距空口连接标识,各个 WiMAX终端使用的这个值都是一样的,所以 CPE 不能仅从这个连接标识与队列对应上, 因此当 CPE发现消息头中的连接标识是 初始测距空口连接标识, 还需要进一步从消息中取出移动终端的 MAC地址, 通过初始测距空口连接标识和移动终端的 MAC地址一起才能够找到对应的緩 存队列。
CPE也可以只建立一个初始测距緩存队列, 对于所有连接到此 CPE的移动 终端的初始测距请求都緩存到这个队列, 然后逐个在竟争期发送。 如此, 步骤 505、 506就可以省略。
508: CPE侦听 BS的广播消息, 从 ULMAP中定位竟争期, 从初始测距空口 连接的緩存队列中取出待发送的消息, 并将其在竟争期发送。 如果 CPE上存在 多个移动终端的初始测距空口连接的緩存队列,且其中都有待发送的消息, 则 CPE按照自己的算法依次或随机取出其中的消息发送。
509: CPE所附着基站接收到所述冲突测距请求消息后, 因为其中包含原 基站的 BSID, 且消息中指示测距的目的是切换, 则 CPE所附着基站 1触发切换 过程。 所述切换过程包含 CPE所附着基站与所述移动终端所附着的原基站 2的 交互, 以及与 WiMAX无线网络的网关设备交互等, 该切换的具体过程可参见 WiMAX规范, 此处不再赘述。 如果所述冲突测距请求消息指示是初始入网, 则 CPE所附着基站 1为所述移动终端完成入网预附着过程, 具体过程可参见 WiMAX规范, 此处不再赘述。 510: CPE所附着基站 1向所述移动终端发送冲突测距响应消息。 所述冲突 测距响应消息的所有帧头仍然使用初始测距空口连接标识,并且消息中也必须 包含移动终端的 MAC地址。 该消息中包含了基站 1为移动终端分配的后续要使 用的连接。 CPE从下行物理子帧中接收所述冲突测距响应消息。
需要说明的是, 所述冲突测距响应消息, 需要通过帧头的连接标识以及其
MAC地址来识别其归属移动终端。 CPE收到所述消息后,根据消息中的初始测 距空口连接标识和 MAC地址, 将其放入其归属移动终端对应的初始测距空口 连接下行緩存队列。
511 : CPE从初始测距空口连接下行緩存队列取出待转发的 WiMAX空口 MAC消息 (即冲突测距响应消息), 从对应的隧道发送到移动终端。
512: 移动终端接收到冲突测距响应消息后, 从中取出获得的连接标识以 及其属性信息, 并向 CPE发送共享天线请求消息, 该消息中包携带当前获取到 的连接标识以及其属性信息 ,而初始测距空口连接标识以及其属性信息可以不 用再包含在其中了。
513: CPE接收到所述共享天线请求消息后, 根据所述请求消息中携带的 连接标识以及其属性信息, 建立对应的緩存队列, 而初始测距连接緩存队列则 可以删除。
所述步骤 513之后, 移动终端通过 CPE与无线网络的进行数据交互的过程 与图 3步骤 307至步骤 313所描述的过程一致, 此处不再赘述。
值得说明的是, 当移动终端需要断开与 CPE的 WiFi连接而直接从 WiMAX 空口连接基站时,移动终端在 WiFi接口上的解除关联过程将直接导致 CPE将移 动终端相关的连接緩存队列全部清除, 即使移动终端什么都没做就离开 CPE, CPE上的 WiFi AP模块将因为接收不到移动终端的 WiFi信号而自动解除与移动 终端的关联,这同样触发 CPE将移动终端相关的连接緩存队列全部清除。当然, 移动终端也可以在未与 CPE上的 WiFi AP解除关联之前就给 CPE发送一个消息 表明其要离开 CPE, 以便 CPE即时删除移动终端相关的连接緩存队列。
