实施例三 图 3示出了根据本发明实施例的上报 T-CPICH的信道状态的方法的流程 图, 该方法以资源状态指示过程上报 T-CPICH的信道状态为例进行说明, 该 方法包括以下步 4聚: 步骤 S302, NodeB监测逻辑资源变化情况, 当 T-CPICH信道状态发生 变化时记录 T-CPICH信道状态, 并立即触发资源状态指示过程; 步骤 S304, NodeB通过 Resource Status Indication (资源状态指示)消息 把 NodeB的逻辑资源通知给 RNC, 本实施例在资源状态指示的信元 Cell Information (为 3GPP 25.433协议中现有信元, 表示小区信息) 中携带信元 Time-multiplexed CPICH Information信息( T-CPICH信息;), T-CPICH信息表 示 NodeB中的 1MB小区的 T-CPICH信道^ I大况。 上述 T-CPICH信息包括资源操作状态字段 Resource Operational State和 可使用状态字段 Availability Status; NodeB检查 T-CPICH的信道状态为正常 时,设置资源操作状态字段为使能状态,可使用状态字段为空;检查 T-CPICH 的信道状态为异常时, 设置资源操作状态字段为非使能状态, 可使用状态字 段为指定值。 本实施例的 RNC可 居资源状态指示消息中的 Time-multiplexed CPICH Information信息( T-CPICH信息)来获知 NodeB内 1MB小区的 T-CPICH信 道状态,解决 RNC侧和 NodeB侧信道资源状态不一致的问题, 居 T-CPICH 信道 况决定后续如何处理 1MB相关业务, 更好地实现 1MB相关业务。 实施例四 图 4示出了根据本发明实施例的基站的结构框图, 该基站包括检查模块 402 , 设置为检查 T-CPICH的信道状态; 上报模块 404 , 设置为向无线网络 控制器 50上报 T-CPICH的信道状态。 本实施例通过上报模块 404上报 T-CPICH的信道状态,可以使无线网络 控制器获取到基站内 1MB小区的 T-CPICH信道状态, 进而可以使无线网络 控制器得知 T-CPICH信道状态是否异常, 保持自身的资源状况与基站一致, 利于基站完成 1MB相关业务, 实现 1MB功能。
本实施例的基站可以通过两种方式上报 T-CPICH的信道状态,一种是通 过在审计过程中上报, 另一种是通过资源状态指示过程中上表; 这两种方式 都可以在原有的信令消息中携带新增信元 Time-multiplexed CPICH
Information即 T-CPICH信息实现。 基于第一种实现方式, 本实施例提供的检查模块 402包括: 接收单元, 设置为接收来自无线网络控制器的审计请求消息; 第一检查单元, 设置为检 查 T-CPICH的信道状态;上报模块 404设置为接收单元收到上述审计请求消 息后, 向无线网络控制器发送审计响应消息, 该审计响应消息携带表示 T-CPICH的信道状态的 T-CPICH信息。 基于第二种实现方式, 本实施例提供的检查模块 402包括: 逻辑资源监 测单元, 设置为监测基站的逻辑资源是否发生变化; 第二检查单元, 设置为 检查 T-CPICH的信道状态;上报模块 404设置为向无线网络控制器发送资源 状态指示消息, 该资源状态指示消息携带表示 T-CPICH的信道状态的 T-CPICH信息。 上述 T-CPICH信息包括资源操作状态字段 Resource Operational State和 可使用状态字段 Availability Status; 上报模块 404设置为 T-CPICH的信道状 态为正常时, 设置资源操作状态字段为使能状态, 可使用状态字段为空; T-CPICH的信道状态为异常时, 设置资源操作状态字段为非使能状态, 可使 用状态字段为指定值。 本实施例的基站通过在审计过程或资源状态指示过程中上报 T-CPICH 的信道状态, 可以在用较少的信令开销基础上, 实现无线网络控制器获取到 T-CPICH的信道状态, 进而保障基站和无线网络控制器的资源状态一致, 使 1MB技术得以顺利实现。 实施例五 图 5示出了根据本发明实施例的上报 T-CPICH的信道状态的系统结构框 图, 该系统包括基站 60和无线网络控制器 50 , 基站 60包括检查模块 602 , 设置为检查 T-CPICH的信道状态; 上报模块 604 , 设置为向无线网络控制器 50上报 T-CPICH的信道状态; 无线网络控制器 50, 设置为接收来自基站 60 上 4艮的 T-CPICH的信道状态。
本实施例通过上报 T-CPICH的信道状态, 可以使无线网络控制器 50获 取到基站 60内 1MB小区的 T-CPICH信道状态, 进而可以使无线网络控制器 50得知 T-CPICH信道状态是否异常, 保持自身的资源状况与基站 60—致, 利于基站完成 1MB相关业务, 实现 1MB功能。 本实施例的基站 60与实施例四中的基站的实现方式相同, 这里不再详 述。 例如, 基站 60可以通过两种方式上报 T-CPICH的信道状态, 一种是通 过在审计过程中上 ·ί艮, 另一种是通过资源状态指示过程中上 ·ί艮; 这两种方式 都可以在原有的信令消息中携带新增信元 Time-multiplexed CPICH
Information即 T-CPICH信息实现。 基于第一种实现方式, 本实施例提供的无 线网络控制器 50还设置为向基站 60发送审计请求消息。 本实施例的 T-CPICH信息与上述实施例中的 T-CPICH信息相同, 这里 不再详述。 本实施例的基站通过在审计过程或资源状态指示过程中上报 T-CPICH 的信道状态, 可以在用较少的信令开销基础上, 实现无线网络控制器获取到 T-CPICH的信道状态, 进而保障基站和无线网络控制器的资源状态一致, 更 好地实现 1MB技术。 以上实施例中的基站的小区支持 1MB业务, 也就是小区是 1MB小区。 从以上的描述中可以看出, 本发明实现了如下技术效果: NodeB通过上 4艮 T-CPICH的信道状态, 可以使 RNC能够及时得知 NodeB中的 1MB小区 的 T-CPICH的信道状况, 解决 RNC侧和 NodeB侧信道资源状态不一致的问 题, 更好地实现 1MB相关业务。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件 结合。
