Description

一种信息传输方法、 系统及睡眠功能设备
技术领域
[01] 本发明涉及通信技术领域, 特别涉及一种信息传输方法、 系统 及睡眠功能设备。
背景技术
[02] 在现有的通信网络中, 有些电池供电的通信设备为具有睡眠功 能的终端设备( Sleeping End Device, SED ), 是指可以进入睡眠状态 不接受或发送信号, 并且在一段时间后唤醒的设备, 比如在紫蜂 ( Zigbee )无线网络中的通信设备等。
[03] 当 SED设备加入网络后会 睡眠状态来节省设备的电量,在 睡眠状态下的 SED设备不能接收网络中的其它通信设备发送的信息, 且 SED设备会周期性地唤醒后以相同的频率发送轮询 ( poll )消息给 网络中的组设备比如协调管理设备等, 从而获知组设备需要发送给 SED设备的数据, 并接收组设备发送的信息。 在现有技术中 SED设 备周期性地唤醒来接收组设备发送的数据,但是组设备在发送数据时 不会周期性地发送, 就会出现当 SED设备处于睡眠状态时, 组设备 才发送数据, 从而接收不到组设备发送的数据。
发明内容
[04] 本发明实施例提供一种信息传输方法、 系统及睡眠功能设备, 尽可能保证在组设备发送信息时, SED设备处于唤醒状态来接收组设 备发送的信息。
[05] 本发明实施例提供一种信息传输方法, 包括如下步骤:
[06] 在预置的时间窗内确定是否接收到组设备发送的信息, 如果 是, 重置所述预置的时间窗; 所述预置的时间窗中包括若干个子时间 窗, 所述子时间窗的时长为发送轮询消息的时间间隔;
[07] 在所述重置后的时间窗内发送轮询消息给组设备, 以接收所述 组设备发送的信息。 [08] 本发明实施例提供一种睡眠功能的设备, 包括:
[09] 信息确定单元, 用于在预置的时间窗内确定是否接收到组设备 发送的信息; 所述预置的时间窗中包括若干个子时间窗, 所述子时间 窗的时长为发送轮询消息的时间间隔;
[10] 重置单元, 用于所述信息确定单元在预置的时间窗内确定接收 到组设备发送的信息, 重置所述预置的时间窗;
[11] 轮询发送单元, 用于在所述重置后的时间窗内发送轮询消息给 组设备, 以接收所述组设备发送的信息。
[12] 本发明实施例中,当 SED设备在预置的时间窗内接收到组设备 发送的信息, 则重置预置的时间窗, 并在重置后的时间窗内发送轮询 消息给组设备。 这样 SED设备根据接收到组设备发送的信息来调整 SED设备保持发送轮询消息的频率, 从而调整 SED设备处于唤醒状 态的时长,尽可能保证在组设备发送信息的期间, SED设备处于唤醒 状态从而接收组设备发送的信息。
附图说明
[13] 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下 面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显 而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领 域普通技术人员来讲, 在不付出创造性劳动性的前提下, 还可以根据 这些附图获得其他的附图。
[14] 图 1是本发明实施例提供的一种信息传输方法的流程图;
[15] 图 2是本发明实施例中提供的在分配网络下进行信息传输的方 法流程图;
[16] 图 3 是本发明实施例提供的一种睡眠功能的设备的结构示意 图;
[17] 图 4是本发明实施例提供的另一种睡眠功能的设备的结构示意 图。
具体实施方式 [18] 下面将结合本发明实施例中的附图, 对本发明实施例中的技术 方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一 部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域 普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施 例, 都属于本发明保护的范围。
[19] 本发明实施例提供一种信息传输方法,主要是当 SED设备在加 入到操作 ( operation )网络或加入到分配( commission )网络后 , 接 收网络中组设备发送的信息的方法,其中组设备可以为网络中的协调 ( Coordinate )管理等设备, 而 SED设备可以包括 Zigbee无线网络 中的受控设备等, 本实施例的方法是 SED设备所执行的方法, 流程 图如图 1所示, 包括:
[20] 步骤 101, 在预置的时间窗内确定是否接收到组设备发送的信 息, 如果是, 执行步骤 102和 103, 如果否, 执行步骤 104。 其中该 预置的时间窗中包括若干个子时间窗,则每个子时间窗的时长为发送 轮询消息的时间间隔。
[21] 可以理解,在分配网络下,组设备可以配置网络中 SED设备上 的参数, 比如网络资源或限制信息等参数, 并在对 SED设备配置完 成后进入操作网络, 这样在分配网络中, 组设备要发送配置 ( configuration )信息给 SED设备。在这个配置的过程中, 当有 SED 设备加入分配网络, 该 SED设备需要启动一个预先设置的时间窗, 并在预置的时间窗内发送轮询消息给组设备,来得知组设备在分配网 络中发送给 SED设备的配置信息。
[22] 在操作网络下, 组设备对其它设备进行网络的协调管理, 并可 以发送一些管理信息给其它设备, 比如发送读取命令、 绑定请求 ( binding request )或^^配置 ( report configure )命令等命令给其 它设备。 在这个过程中, 当有 SED设备加入到操作网络时, 该 SED 设备会启动一个预先设置的时间窗,并在预置的时间窗内发送轮询消 息给组设备, 来得知组设备在操作网络中发送给 SED设备的操作信 息, 启动的时间窗会随着数据量的变化而变化。
[23] 其中考虑到分配网络下和操作网络下, 组设备发送信息的频率 差异,在分配网络下启动的时间窗和在操作网络下启动的时间窗可以 相同,也可以不同,这里预置的时间窗中可以包括若干个(比如 n个, n为大于 1的整数)子时间窗,每个子时间窗的时长为该 SED设备发 送轮询消息的时间间隔 gap ,而子时间窗的个数即为 SED设备发送轮 询消息的次数 times,则预置的时间窗即为 gap*times,例如一个 SED 设备发送 5次轮询消息且每隔 4 ( s )秒发送一次, 则该 SED设备中 预置的时间窗为 4s*5=20s。
[24] 如果 SED设备在预置的时间窗内没有接收到组设备发送的信 息(操作信息或配置信息), 则需要进入睡眠状态来节省设备的电量 消耗; 如果 SED设备在预置的时间窗内每次接收到组设备发送的信 息, 则认为组设备 可能还要发送信息, 该 SED设备就不能停止 发送轮询消息, 需要保持数据轮询的频率, 则执行步骤 102和 103, 来充分保证当组设备在发送信息时, SED设备处于数据轮询状态来接 收组设备发送的信息。 其中 SED设备与组设备之间的通信可以经过 路由设备。
[25] 需要说明的是, SED设备在预置的时间窗内, 发送两次轮询消 息的间隔内即在子时间窗内是睡眠的,只有在发送轮询消息的时候才 唤醒, 一般唤醒状态持续几十到几百个亳秒。 比如 SED设备在第 1 个几百个亳秒内唤醒发送了轮询消息给组设备来接收组设备发送的 信息后, SED设备则进入睡眠状态, 在 4s后该设备又唤醒几百个毫 秒来进行轮询。
[26] 步骤 102, 重置 SED设备中预置的时间窗, 即将开始启动的时 间窗设置为预置的时间, 例如当 SED设备中启动了一个 20s的时间 窗,在发送轮询消息的过程中,该启动的时间窗随着数据量发生变化, 当在 5s的时候 SED设备接收到组设备发送的信息, 则将该时间窗重 置为 20s。
[27] 步骤 103, 在重置后的时间窗内发送轮询消息给组设备, 以接 收组设备在操作网络或分配网络下发送的信息。
[28] 步骤 104, 长时期地进入睡眠状态, 并在一定的时间后唤醒。
[29] 可以理解, 当 SED设备长时期的进入睡眠状态后,用户可以通 过操作该 SED设备来唤醒该设备, 比如给该 SED设备发出一个用户 操作的唤醒命令; 而 SED设备也可以根据设备的配置来自动在一定 时候后唤醒。 则在该长时期地睡眠过程中, 如果组设备有信息发送给 SED设备, 如果发现该 SED设备处于睡眠状态, 则会先緩存发送的 信息, 当 SED设备唤醒后向组设备发一个唤醒指示消息, 这样组设 将緩存的信息发送给该 SED设备。
[30] 可见,本发明实施例中, 当 SED设备在预置的时间窗内接收到 组设备发送的信息, 则重置预置的时间窗, 并在重置后的时间窗内发 送轮询消息给组设备。 这样 SED设备根据接收到组设备发送的信息 来调整 SED设^ 发送轮询消息的频率, 从而调整 SED设备处于 唤醒状态的时长,尽可能保证在组设备发送信息的期间, SED设备处 于唤醒状态从而接收组设备发送的信息。
[31] SED设备可以通过上述步骤 101到 104来滑动时间窗,具体时 间窗中所包括的子时间窗数量和子时间窗的时长是不变的,在一个具 体的实施例中, SED设备除了执行上述步骤 101到 104之外,还可以 根据一定的策略来调整该预置的时间窗的大小,比如缩短或延长时间 窗, 具体地, SED设备可以判断该 SED设备接收组设备发送信息的 密度是否大于预置的上限值, 如果是, 说明组设备发送每个信息给 SED设备的时间间隔较短, SED设备可以增加发送轮询消息的频率, 并按照增加后的频率发送轮询消息, 这样就可以保证 SED设备唤醒 的连续性, 并增加 SED设备处于唤醒状态的时间, 以接收组设备以 高密度发送的信息。 其中 SED设备在增加发送轮询消息的频率时, 具体可以在预置的时间窗内子时间窗个数一定的情况下,缩短至少一 个子时间窗的时长;也可以增加预置的时间窗内所包括的子时间窗个 数, 并可以同时缩短子时间窗的时长。
[32] 如果 SED设备接收组设备发送信息的密度不大于预置的上限 值或发送信息的密度小于一个下限值, 说明组设备发送每个信息给 SED设备的时间间隔较长, 则 SED设备不需要高频率地发送轮询消 息给组设备, SED设备可以减小发送轮询消息的频率,并按照减小的 频率发送轮询消息,这样可以节省 SED设备的电量消耗。其中, SED 设备在减小发送轮询消息的频率时,具体可以在在子时间窗个数一定 的情况下增加子时间窗的时长;也可以减小预置的时间窗内所包括的 子时间窗个数, 并可以同时增加子时间窗的时长。 这样在调整时间窗 后, 时间窗中所包括的每个子时间窗的时长可以相等也可以不相等。
[33] 上述预置的上限值大于下限值,且 SED设备接收组设备发送信 息的密度可以表示组设备发送每个信息的间隔,具体地, SED设备在 具体判断该密度是否大于预置的上 P艮值或是否小于预置的下限值时, 可以在 SED设备唤醒以发送轮询消息的几十到几百个亳秒内判断, 且可以根据接收到组设备发送的两个信息之间的时间间隔来衡量该 密度, 并根据判断的结果来调整时间窗。
[34] 且需要说明的是, 上述所述的预置时间窗内所包括的每个子时 间窗的时长可以相等, 也可以不相等; 且在进行调整时间窗时, 可以 按照线性或非线性地增加或缩短子时间窗的时长, 比如将子时间窗 1 的时长增加 a, 将子时间窗 2的时长增加 2a。
[35] 在另一个具体的实施例中, 在分配网络下, 由于组设备发送给 SED设备的配置信息比较重要, 就需要 SED设备处于持续发送轮询 消息的状态来接收组设备发送的配置信息, 比如通过调整分配网络下 SED设备发送轮询消息的频率来实现, 具体可以根据 SED设备接收 组设备发送的配置信息的密度来调整。
[36] 具体地,分配网络下的 SED设备具体可以通过执行如下的步骤 来进行信息的传输, 从而调整发送轮询消息的频率, 流程图如图 2所 示, 包括:
[37] 步骤 201 , 确定在预置的时间内或当超过预置的时间窗时, 是 否接收到组设备在分配网络下发送的配置信息,如果不是,说明 SED 设备处于唤醒状态的这段时间内组设备都没有发送配置信息,则组设 备发送配置信息的密度较小, 为了节省 SED设备的电量消耗, 可以 执行步骤 202到 204; 如果是, 则执行步骤 205, 即按照预置的时间 窗来发送轮询消息。其中预置的时间需要小于或等于该预置的时间窗 的时长。
[38] 步骤 202, 减小发送轮询消息的频率。 具体地, 可以在预置的 时间窗所包括的子时间窗个数一定的情况下增加子时间窗的时长,也 可以减小预置的时间窗内所包括的子时间窗个数,还可以在减小预置 的时间窗内所包括的子时间窗个数的同时, 增加子时间窗的时长。
[39] 步骤 203, 按照减小后的频率发送轮询消息给组设备。
[40] 步骤 204, 当接收到组设备在分配网络下发送的配置信息, 恢 复使用预置的时间窗发送轮询消息给组设备,即使用调整前的时间窗 来发送轮询消息。
[41] 例如,当 SED设备在很长的时间内都没有接收到组设备发送的 配置信息, SED设备可以增加原来是 5s的子时间窗的时长, 比如从 原来的 5s增加到 6s, 这样 SED设备发送轮询消息的频率从 1次 /5s, 减小到 1次 /6S,在这个过程中,只要接收到组设备发送的配置信息后, 即恢复使用 1次 /5s的频率来发送轮询消息。
[42] 需要说明的是, 当 SED设备接收到组设备发送的配置信息后, 根据该配置信息对 SED设备进行配置完成后, 可以触发重启程序来 重新启动该 SED设备, 使得该 SED设备进入操作网络中。
[43] 可见, 本实施例中, 当处于分配网络下, SED设备会根据是否 接收到组设备发送的配置信息的状态, 来调整 SED设备发送轮询消 息的频率,尽可能保证在组设备发送配置信息的期间, SED设备处于 唤醒状态从而接收组设备发送的配置信息,并同时在组设备发送配置 信息的密度较小时, 通过减小 SED设备发送轮询消息的频率来节省 设备的电量消耗。
[44] 本发明实施例还提供一种睡眠功能的设备, 即上述的 SED设 备, 结构示意图如图 3所示, 包括:
[45] 信息确定单元 10,用于在预置的时间窗内确定是否接收到组设 备发送的信息; 所述预置的时间窗中包括若干个子时间窗, 所述子时 间窗的时长为发送轮询消息的时间间隔;
[46] 重置单元 11, 用于如果所述信息确定单元 10在预置的时间窗 内确定接收到组设备发送的信息, 重置所述预置的时间窗;
[47] 轮询发送单元 12, 用于在所述重置单元 11重置后的时间窗内 发送轮询消息给组设备, 以接收所述组设备发送的信息。
[48] 可以理解,在该 SED设备中可以包括接收组设备发送的信息的 单元即信息接收单元。
[49] 本发明实施例的 SED设备中, 如果信息确定单元 10确定在预 置的时间窗内接收到组设备发送的信息, 则重置单元 11重置预置的 时间窗, 并由轮询发送单元 12在重置后的时间窗内发送轮询消息给 组设备。 这样 SED设备根据接收到组设备发送的信息来调整 SED设 ^ 持发送轮询消息的频率, 从而调整 SED设备处于唤醒状态的时 长,尽可能保证在组设备发送信息的期间, SED设备处于唤醒状态从 而接收组设备发送的信息。
[50] 参考图 4所示, 在一个具体的实施例中, 睡眠功能的设备除了 可以包括如图 3所示的结构外,还可以包括: 时间窗启动单元 13、接 收密度判断单元 14、 频率调整单元 15和睡眠单元 16, 其中: [51] 时间窗启动单元 13, 用于在加入操作网络或分配网络时, 启动 预先设置的时间窗。且在操作网络和分配网络中启动的时间窗可以相 同, 也可以不同, 一般来说, 在分配网络下会有大量信息从组设备中 发出, 则和操作网络相比, 在分配网络中时间窗启动单元 13启动的 时间窗中所包括的子时间窗的数量较多, 且子时间窗的时长较短。
[52] 接收密度判断单元 14,用于判断接收所述组设备发送信息的密 度是否大于预置的上限值,或用于判断组设备发送信息的密度是否小 于预置的下限值; 其中预置的上限值大于下限值;
[53] 频率调整单元 15, 用于当所述接收密度判断单元 14判断接收 所述组设备发送信息的密度大于预置的上限值时,增加发送所述轮询 消息的频率; 当所述接收密度判断单元 14判断接收所述组设备发送 信息的密度不大于预置的上 P艮值或小于预置的下限值时,减小发送轮 询消息的频率。其中增加和减小发送轮询消息的频率的具体方法如方 法实施例中所述, 在此不进行赘述。
[54] 睡眠单元 16, 用于当所述信息确定单元 10在预置的时间窗内 确定未接收到组设备在操作网络下发送的信息, 长期地进入睡眠状 态 o
[55] 在本发明实施例中, 当该设备加入分配网络时, 时间窗启动单 元 13可以启动一个预先设置的时间窗来控制设备保持发送轮询消息 的状态, 从而控制处于唤醒状态的时长。 在分配网络下, 信息确定单 元 10还可以确定在预置的时间内或当超过所述预置的时间窗时, 是 否接收到所述组设备在分配网络下发送的配置信息, 如果是, 则轮询 发送单元 12按照预置的时间窗来发送轮询消息, 其中如果是在预置 的时间窗内接收组设备在分配网络下发送的配置信息,则可以先由重 置单元 11重置时间窗后,轮询发送单元 12按照重置后的时间窗来发 送轮询消息; 如果不是, 则频率调整单元 15会减小轮询发送单元 12 发送轮询消息的频率来节省设备的电量消耗, 具体地, 可以增加时间 窗启动单元 13启动的预置的时间窗中子时间窗的个数, 或缩短所述 预置的时间窗中子时间窗的时长等, 并由轮询发送单元 12按照频率 调整单元 15调整后的频率发送轮询消息给所述组设备, 以接收所述 组设备在配置网络下发送的配置信息。
[56] 且当该 SED设备在接收到所 且设备在分配网络下发送的配 置信息后, 可以触发轮询发送单元 12可以恢复使用所述预置的时间 窗发送轮询消息给所述组设备,以接收所述组设备在分配网络下发送 的配置信息。 在一个具体的实施例中, 当 SED设备中的信息接收单 元接收到组设备发送的配置信息 ,并由配置单元按照该配置信息进行 配置完成后,可以触发该 SED设备中的重启单元,来重新启动该 SED 设备, 重启后的 SED设备即 ii/V操作网络。
[57] 当^操作网络下, 信息确定单元 10会在预置的时间窗内确 定是否接收到组设备在操作网络下发送的信息, 如果是, 则重置单元 11重置时间窗启动单元 13启动的时间窗,并由轮询发送单元 12发送 轮询消息; 如果不是, 则睡眠单元 16进入睡眠状态。 在操作网络中 组设备发送信息给 SED设备的过程中, 当 SED设备唤醒由轮询发送 单元 12发送轮询消息时, 如果接收密度判断单元 14判断 SED设备 接收组设备发送信息的密度大于预置的上限值时,可以由频率调整单 元 15增加发送轮询消息的密度来保证 SED设备被唤醒的连续性, 并 充分接收组设备发送的信息, 则轮询发送单元 12会按照增加后的频 率发送轮询消息; 如果接收密度判断单元 14判断 SED设备接收组设 备发送信息的密度不大于预置的上限值或小于预置的下限值时,可以 由频率调整单元 15减小发送轮询消息的密度来节省 SED设备的电量 消耗, 则轮询发送单元 12会按照减小后的频率发送轮询消息。
[58] 本发明实施例还提供一种信息传输系统, 包括睡眠功能的设备 和组设备, 其中:
[59] 睡眠功能的设备, 用于在预置的时间窗内确定是否接收到组设 备发送的信息, 如果是, 重置所述预置的时间窗; 所述预置的时间窗 中包括若干个子时间窗,所述子时间窗的时长为发送轮询消息的时间 间隔; 在所述重置后的时间窗内发送轮询消息给组设备, 以接收所述 组设备发送的信息;
