发送模块 20连接至确定模块 10,用于根据由确定模块 10确定的基站的状态 构造用于指示基站状态的基站状态信息, 并发送基站状态信息以供其它网元 接收, 这里, 其它网元可以包括以下至少之一: 终端、 接入月 务网、 连接月 务网、 中继站、 其它基站。 基站状态信息可以用于指示基站是否能够正常工作、是否丢失与其上层 网元的回程连接、 是否允许更多的终端接入、 是否能够为特定的业务类型或 业务类型组提供服务、 是否能为特定的终端或终端组提供服务。 基站状态信 息的具体构造方式将在其后的实例中结合表 1至表 4进行详细说明。 图 2示出了根据本实施例的基站的优选结构的实例。 如图 2所示, 在图 1所示的结构的基础上 ,图 2进一步示出了发送模块 20的结构。如图 2所示 , 发送模块 20可以包括: 第一发送子模块 201、 第二发送子模块 203、 第三发 送子模块 205、 第四发送子模块 207、 和控制模块 209。 发送模块 20中各个模块的功能如下: 第一发送子模块 201用于通过同 步信道发送基站状态信息; 第二发送子模块 203用于通过广播信道发送基站 状态信息; 第三发送子模块 205用于通过组播信道发送基站状态信息; 第四 发送子模块 207用于通过单播信道发送基站状态信息; 控制模块 209连接至 第一发送子模块 201、 第二发送子模块 203、 第三发送子模块 205、 和第四发 送子模块 207, 用于选择第一发送子模块 201、 第二发送子模块 203、 第三发 送子模块 205、 和第四发送子模块 207中的一个进行发送。 其中,发送模块 20可以在某些消息或信令来携带上述的基站状态信息。 例如, 在第一发送子模块 201发送消息时可以选择同步信道发送的序列 ID, 终端基于序列 ID就能够获得基站状态信息。 优选地 , 为了节省网络开销 , 发送模块 20可以在基站与基站的上层网 元通信中断, 或基站本身供电不足等异常情况下向终端发送基站状态信息。 根据本实施例的基站能够将其状态通知给终端,使得终端能够根据基站 的状态进行后续处理, 避免了由于基站已经处于或即将处于不能正常工作的 状态 (包括基站本身的供电出现异常、 基站丢失其上层网元的回程连接、 基 站的上层网元的通信出现拥挤、 基站指示已与其建立连接的终端、 以其为服 务基站的终端或其正在提供服务的终端切换到其它基站等情况, 其中, 基站 指示切换到其它基站的终端是已与基站建立连接的全部终端或部分终端, 或 以基站为服务基站的全部终端或部分终端 , 或基站正在提供服务的全部或部 分终端), 有助于?丈善终端的 务质量。 装置实施例二 在本实施例中, 提供了一种终端, 用于接收根据上一实施例的基站发送 的基站状态信息, 并根据基站的状态进行处理。 如图 3所示 艮据本实施例的终端可以包括接收模块 30和处理模块 40。 图 3中所示的各个模块的功能如下: 接收模块 30用于接收来自基站的 用于指示基站的状态的基站状态信息; 处理模块 40连接至接收模块 30 , 用 于根据接收模块 30接收的基站状态信息进行后续处理。 根据基站状态信息指示的不同状态以及终端与基站的关系 ,处理模块可 以使终端不向基站发送接入请求(接入试探)、 不将基站作为进行切换的目标 基站、 执行切换流程或网络重入流程 , 具体的处理过程将在其后的实例中进 行详细描述。 因此, 在基站出现异常的情况下, 才艮据本发明实施例的终端能 够不停留在该基站下或不切换至该基站, 从而保证了终端的服务质量。 方法实施例 在本实施例中, 提供了一种基站状态的指示方法。 如图 4所示, 才艮据本 实施例的基站状态的指示方法包括步骤 S402和步骤 S404: 步骤 S402, 基站 (例如, 家庭基站)发送用于指示其状态的基站状态 信息给其它网元, 这里其它网元可以包括以下至少之一: 终端、接入服务网、 连接月 务网、 中继站、 其它基站等。 步骤 S404, 其它网元接收基站状态信息, 并根据基站状态信息以及其 它网元本身的犬态进行后续的处理。 步骤 S402中发送的基站状态信息用于指示基站即将处于或已经处于以 下状态之一: 是否能够正常工作、 是否允许更多的终端接入、 是否能够为特 定的业务类型或业务类型组提供服务、 是否能为特定的终端或终端组提供服 务。 基站可以通过同步信道、 广播信道、 组播信道、 和单播信道中的一个来 发送指示基站状态的信息。 其中, 基站不能正常工作的状态 (out of service ) 包括: 基站本身的供电出现异常、 基站丢失其上层网元的回程连接、 基站的 上层网元的通信出现拥挤、 基站指示已与其建立连接的终端或以其为月 务基 站的终端或其正在提供服务的终端切换到其它基站等情况, 其中, 基站指示 切换到其它基站的终端是已与基站建立连接的全部终端或部分终端 , 或以基 站为 ^务基站的全部终端或部分终端 , 或基站正在提供 务的全部或部分终 端。 并且, 在进行信息发送时, 可以在某些消息或信令中携带上述的基站状 态信息。 下文中描述的终端是已与基站建立连接的全部终端或部分终端 ,或以基 站为 ^务基站的全部终端或部分终端 , 或基站正在提供 务的全部或部分终 端。 优选地, 在基站即将处于或已经处于不能正常工作的状态的情况下, 基 站可以向终端发送邻区列表信息, 终端根据该基站发送的邻区列表可以选择 后续的处理, 例如, 执行切换等。 基站发送邻区列表信息的方式包括以下至 少之一: 广播、 组播、 单播。 下面将详细描述终端根据基站状态信息中携带的状态、以及该终端与基 站的关系进行的后续处理。 在基站不是终端的服务基站,且基站状态信息指示基站即将处于或已处 于不能正常工作的状态的情况下 (终端根据基站状态信息得知基站不能正常 工作), 在终端接收到基站状态信息之后, 该方法可进一步包括: 终端禁止其 将该基站作为终端进行切换的目标基站, 即, 终端不选择该基站作为自己的 切换目标基站。 在终端未与基站建立连接、 或未通过接入信道向基站发送接入请求, 且 基站状态信息指示基站即将处于或已处于不能正常工作的状态的情况下, 在 终端接收到基站状态信息之后, 该方法可进一步包括: 终端禁止其向基站发 送接入请求(接入试探), 即, 终端不 (should not ) 向该基站发送接入请求。 在终端已与基站建立连接、 或基站正在为终端提供服务、 或基站为终端 的服务基站, 且基站状态信息指示基站即将处于或已处于不能正常工作的状 态的情况下, 在终端接收到基站状态信息之后, 该方法可进一步包括: 终端 执行切换流程或网络重入流程。 其中, 优选地, 终端可以按照标准缺省配置 的时间间隔或与基站协商的时间间隔执行切换流程或网络重入流程。 并且, 在终端接收到基站状态信息后, 可以等待标准缺省配置的时间间 隔或等待与基站协商的时间间隔后执行切换流程或网络重入流程。 在终端执行切换流程或网络重入流程的时刻到达前 ,在终端成功接收到 基站发送的最新的基站状态信息, 且信息指示基站已经恢复正常工作状态的 情况下, 该方法可进一步包括: 终端在执行切换流程或网络重入流程的时刻 到达时不执行切换流程或网络重入流程。 另外, 终端还可以才艮据已经建立的业务类型(业务流连接的类型, 业务 流类型) 确定执行切换流程或网络重入流程的时刻 , 并在该时刻到达时执行 切换流程或网络重入流程。 在终端建立了多个业务流连接的情况下 , 终端可 以根据已经与基站建立业务流连接的业务流中对实时性要求最高的业务流的 情况决定终端执行切换流程或网络重入流程的时刻。 此外, 基站也能够根据 终端已经建立的业务类型 (业务流连接的类型, 业务流类型) 确定终端执行 切换流程或网络重入流程的时刻。 优选地, 基站也可以才艮据终端已经与基站 建立业务流连接的业务流中对实时性要求最高的业务流的情况确定终端执行 切换流程或网络重入流程的时刻。 这里, 对执行时刻的确定主要取决于终端已经建立的业务流类型, 如果 是实时业务流(对服务质量要求艮高的业务,要求业务传输具有艮低的延迟, 即, 对时延很敏感), 则马上执行切换或网络重入, 以保证业务不中断; 如果 是 BE业务流(对服务质量要求较低的业务,允许业务传输具有较大的延迟), 可以考虑在一个时间段之后进行切换, 这样, 在切换的时刻到达前, 如果该 基站恢复正常, 则终端可以继续在该基站下接收业务, 省去了切换的流程, 而且虽然数据会有中断 , 但是并不会影响用户的体验。 此外, 在基站不是终端的 务基站, 且基站状态信息指示基站不允许更 多的终端接入的情况下, 在终端接收到基站状态信息之后, 该方法可进一步 包括: 终端不将基站作为终端进行切换的目标基站。 在终端未与基站建立连接、 或未通过接入信道向基站发送接入请求, 且 基站状态信息指示基站不允许更多的终端接入的情况下, 在终端接收到基站 状态信息之后, 该方法可进一步包括: 终端不向基站发送接入请求 (接入试 探)。 在基站不是终端的服务基站,且基站状态信息指示基站不能为终端已经 建立的业务连接所对应的业务类型提供^^务或不能为包括终端建立的业务连 接所对应的业务类型的特定业务类型组提供服务的情况下 , 在终端接收到基 站状态信息之后, 该方法可进一步包括: 终端不将基站作为终端进行切换的 目标基站。 在终端已与基站建立连接、 或基站正在为终端提供服务、 或基站为终端 的 ^^务基站, 且基站状态信息指示基站不能为终端已经建立的业务连接所对 应的业务类型提供服务或不能为包括终端建立的业务连接所对应的业务类型 的特定业务类型组提供^^务的情况下, 在终端接收到基站状态信息之后, 该 方法可进一步包括: 终端执行切换流程或网络重入流程。 在基站不是终端的服务基站 ,且基站状态信息指示基站不能为终端或终 端所在的特定终端组提供服务的情况下 , 在终端接收到基站状态信息之后 , 该方法可进一步包括: 终端不将基站作为终端进行切换的目标基站。 在终端未与基站建立连接、 或未通过接入信道向基站发送接入请求, 且 基站状态信息指示基站不能为终端或终端所在的特定终端组提供 务的情况 下, 在终端接收到基站状态信息之后, 该方法可进一步包括: 终端不向基站 发送接入请求 (接入试探)。 在终端已与基站建立连接、 或基站正在为终端提供服务、 或基站为终端 的月 务基站 , 且基站状态信息指示基站不能为终端或终端所在的特定终端组 提供服务的情况下,在终端接收到基站状态信息之后, 该方法可进一步包括: 终端执行切换流程或网络重入流程。 下面将结合具体实例描述本发明。 图 5是实例 1至实例 13中基站选择 同步序列并在同步信道上发送基站状态信息的处理流程图。 如图 5所示, 具体包括以下处理: S502, 基站在同步信道上携带指示基 站状态的信息;
