其中, 步骤 S1中更优选的方案是, 移动终端上数据业务节电功能是默认 自动开启的, 用户可以根据特殊需要手动更改设置。 具体进行节电设置的过 程如图 2所示, 包括如下步骤:
步骤 S11 , 用户可通过软件命令设置是否开启数据业务节电功能及参数; 步骤 S12 , 如果用户选择关闭数据业务节电功能, 则移动终端将不进行 数据业务监控, 或者从省电模式中退出;
步骤 S13 , 如果用户选择开启数据业务节电功能, 移动终端将保存相应 的参数。 具体地, 参数为一个定时器 T的计时时长, 也即无数据业务数据传 输的一段时间。 定时器 T的计时时长设置不能太短, 否则不方便一些应用业 务的体验; 同时为了保证能及时起到省电效果, 定时器 T的计时时长设置不 能太长。 较佳地, 为增加用户体验, 可提示用户将定时器 T的计时时长设置 在 5分钟到 20分钟之间, 最后保存用户输入的时长。 可选的, 也可以在移动 终端内预设定时器 T的推荐时长, 在用户选择开启数据业务节电功能后, 直 接使用预设时长。
在完成数据业务节电模式的设置后, 移动终端将根据预设的监控策略对数 据业务实施监控, 一旦监控到一段时间内没有数据业务数据传输时, 将触发 执行省电操作, 具体过程如图 3所示, 包括如下步骤:
步骤 S21 , 判断移动终端是否有数据业务进行;
具体地, 可以扫描所有无线承载, 判断是否有数据业务无线承载存在。 如 果没有数据业务在进行中, 则返回步骤 S21继续扫描; 如有数据业务存在, 进入步骤 S22, 启动定时器 T, 并进入步骤 S23。
步骤 S23 , 判断是否有数据业务数据传输;
具体地, 可以实时监视移动终端数据面是否有有效的数据业务数据 (上行 或下行) 在传输, 如果发现有数据在传输, 则进入步骤 S24 , 定时器 T将被 重新启动, 之后返回步骤 S21 ; 如果没有监测到数据业务数据, 则进入步骤 S25 o
为了保证后续的节电操作不和 NAS 信令发生冲突, 移动终端在进行数据业 务监控时, 应优先保证 NAS信令过程的完整。 NAS信令是移动终端和核心网 之间信令交互非接入层 (NAS )信息, 如鉴权、 业务请求、 连接建立等。 如何 保证定时器 T超时前能有足够的时间处理正在进行的 NAS信令过程, 具体监 控策略如下:
步骤 S25 , 判断是否有 NAS信令传输;
具体地, 可以实时监视移动终端控制面是否有 NAS 信令 (上行或下行) 传 输。 如果没有发现有 NAS信令传输, 则进入步骤 S26 , 判断定时器 T是否超 时, 如果没有超时, 则返回步骤 S23 , 继续进行数据业务数据的实时监测; 如果定时器 T超时,即表明该时间段内没有数据业务数据传输,也没有和 NAS 信令冲突, 则触发移动终端执行省电操作。 如果步骤 S25的判断结果是存在 NAS信令, 则进入步骤 S28。
步骤 S28 , 判断定时器 T离超时的时长是否大于 NAS层的最大定时器时长 TNAS。 NAS层最大定时器时长是指处理各种 NAS信令容许时长中最大时长, TNAS 可以根据 NAS层协议的所有定时器确定, 一般为 30s。 当定时器 T离超时的 时长大于 NAS层的最大定时器时长 TNAS时, 在定时器 T超时前, NAS信令过程 完全可以处理完成, 预期的省电操作不会影响 NAS信令过程, 因此返回步骤 S23做数据业务数据的实时监测, 定时器继续计时; 当定时器 T离超时的时 长小于 NAS层的最大定时器时长 TNAS时, 在定时器 T超时前, NAS信令过程有 可能被省电操作打断, 为了保证 NAS信令过程顺利完成, 需要执行步骤 S29。 步骤 S29 , 调整定时器 T的计时时长, 使其至少 TNAS后才能超时;
具体地,可以直接将定时器 T延长 TNAS,这样等下次到步骤 S25时若仍有 NAS 信令数据, 则定时器 T 离超时时长很可能仍大于 TNAS, 不需要再次经历步骤 S29, 待 NAS信令传输完毕之后, 定时器经由步骤 S26继续计时直到超时, 即 执行省电操作。
进入省电操作, 无线终端芯片即转到休眠状态, 进入省电模式, 避免了存 在数据业务却并无数据业务数据, 比如用户打开网页阅读、 下载歌曲、 上传 资料或发送邮件之后, 忘了关闭网页, 而芯片一直处于工作状态, 无端消耗 掉电池电量以及无端浪费了无线资源的情形。
另一种可替代方案为, 在不影响 NAS 信令过程的前提下, 要确保定时器 T 超时时的实际时长不能与初始设定的时长相差太多。 这里将定时器 T离超时 的时长延长至 TNAS, 这样当下次进行步骤 S25的判断时, 如果 NAS信令已经传 输完毕, 经由步骤 S26等待定时器超时的时间则可较上一种方案更为缩短。 这样既保证了 NAS信令过程能顺利完成, 又确保了定时 T超时时的实际时长 不会因 NAS信令存在带来定时器 T时长的过于增加。
对于调整后的定时器 T的计时时长恢复, 可在定时器 T超时后做出, 即执 行省电操作后的下一次监测到有数据业务运行并启动定时器 T之前, 将定时 器 T的设定值复原, 比如当使用软件定时器时, 设置为每次启动时以默认值 启动。
图 3所示实施例的另一替代方案如图 4所示,在步骤 S28之前增加步骤 S27 , 即自步骤 S25判断出存在 NAS信令之后, 进入步骤 S27 , 直接判断定时器 T 的时长是否小于 NAS层的最大定时器时长 TNAS ;
具体地, 定时器 T的时长如上述实施例中的步骤 S 13中所说明的, 定时器 T 计时时长不能设置太短,所以一般长于 TNAS, 正常情况下,在该时间段内, NAS 信令过程一般能够处理完成。 但如果用户确实设置定时器 T计时时长是小于 TNAS, 则 S27判断出来后进入步骤 S24 , 定时器 T将被重新启动, 然后返回步 骤 S21 ; 如果定时器 T时长是大于 TNAS的, 则进入步骤 S28。
增加步骤 S27的作用在于, 当定时器 T时长小于 TNAS时, 能不进行计算定时 器离超时所剩的时长并与 TNAS做比较的步骤 S28 , 预先判断得出定时器 T时长 小于 TNAS时迅速重启定时器 T , 从而省去步骤 S28 , 也无需在步骤 S29中根据 TNAS对定时器时长做调整, 以及后续恢复定时器 T的预设值了。 上述方法实施例的步骤 S26中, 如果定时器 T超时, 即表明该时间段内 没有数据业务数据传输, 也没有和 NAS信令冲突, 即触发移动终端执行省电 操作, 如图 5所示, 具体步骤如下:
步骤 S31 , 移动终端发送信令连接释放指示给接入网;
步骤 S32 , 接入网释放与移动终端间的无线资源控制层即 RRC连接; 步骤 S33 , 移动终端释放相应的数据业务承载和空口资源, 进入数据业 务节电模式, 减少不必要的耗电, 同时还节省了空口资源。
进入数据业务节电模式释放的只是移动终端和接入网的空口连接, 移动 终端与网络侧还保持着 "虚连接"即核心网还存有移动终端的信息, 如 IP地 址, 且 PDP上下文仍处于激活状态。 一旦用户重新开启数据业务, 移动终端 只需要重新建立与接入网的空口连接, 等待时间很短, 不会影响用户的正常 使用, 具体步骤如下:
步骤 S41 , 用户重新触发数据业务;
步骤 S42 , 移动终端发送数据业务请求给接入网;
步骤 S43 , 接入网配置相应的数据业务承载及空口资源;
步骤 S44, 移动终端重建无线链路, 数据业务恢复。
基于以上实施例的原理和步骤, 本发明还提供了一种移动终端数据业务 节电装置, 如图 6所示, 包括: 设置单元 Ml ; 监控单元 M2; 执行单元 M3。
其中, 设置单元 Ml用于处理用户的设置, 保存省电功能状态(开启或关 闭) 和参数, 并发出命令给监控单元 M2 , 以开启或关闭数据业务节电功能; 监控单元 M2 , 将根据设置单元 Ml 的命令指示, 开启或关闭数据业务监 控。 如果需要执行数据业务监控, 该模块将根据相关的监控策略, 对数据业 务进行监控, 一旦满足数据业务节电策略, 将发出节电执行命令给执行单元 M3;
执行单元 M3 , 根据监控单元 M2 的节电执行命令执行节电操作, 即发送 信令连接释放指示给网络, 等待网络释放 RRC连接, 然后释放相应的数据业 务承载及空口资源, 进入数据业务下的节电模式。
此处另一种替代方案为, 执行单元 M3同时也与设置单元 Ml连接, 如图 6中虚线所示, 根据设置单元 Ml的命令指示, 开启或关闭对监控单元 M2的 节电执行命令的接收。这样, 当关闭省电执行操作时, M3也可处于休眠状态, 不用随时等候监控单元 M2的节电执行命令, 从而更能节约电力。
如图 7所示, 为更为详细的监控单元 M2的内部结构图, 包括监测模块一 至三, 定时器监控模块, 以及与监测模块一、 监测模块二、 定时器监控模块 分别相连的定时器 T。
监测模块一, 用于监测移动终端是否有数据业务进行, 当其监测到有数 据业务时,随即启动定时器 Τ ,并向监测模块二发送有数据业务的指示消息;。
监测模块二, 用于收到监测模块一发送的有数据业务的指示消息后, 监 测移动终端与网络侧是否有数据业务数据在传输, 并当监测到有数据业务数 据传输时, 重启定时器 Τ ; 当监测结果为无数据业务数据时, 向监测模块三 发送无数据业务数据指示消息。
监测模块三, 用于收到监测模块二发送的无数据业务数据指示消息后, 监测是否有 NAS信令数据。 如存在 NAS信令数据, 向定时器监控模块发送有 NAS信令数据指示消息; 如不存在 NAS信令数据, 向定时器监控模块发送无 NAS信令数据指示消息。
定时器监控模块, 用于收到监测模块三发送为无 NAS信令数据指示消息 时, 判断定时器是否超时, 如超时, 则向执行单元发送省电执行命令; 如未 超时, 则可继续监控定时器。 在收到监测模块三发送为有 NAS信令数据指示 消息时, 判断定时器离超时的时长是否小于 TNAS, 如果小于 TNAS则将定时器 T 离超时的时长调整为 TNAS, 或者将定时器 T计时时长直接调整为 T +TNAS ; 如 果大于或刚好等于 TNAS则可继续监控定时器。
定时器监控模块同时可用于定时器超时、 向执行模块发送省电执行命令 时, 将定时器 T的计时时长恢复为默认值或初始设置值, 以便下次的计时。
定时器 T接受来自监控模块一的开始计时指令、 来自监控模块二的重启 定时器指令, 以及定时器监控模块的调整计时时长指令。 在每次定时器超时 之后, 也可由定时器自身恢复至初始计时时长值。
在另一实施例中, 上述实施例中的定时器监控模块在收到监测模块三发 送为有 NAS信令数据指示消息时, 判断定时器 T的计时时长是否小于 TNAS, 当 计时时长小于 TNAS时, 直接重启定时器 T ; 当计时时长大于或等于 TNAS时, 再 判断定时器离超时的时长是否小于 TNAS, 如果小于 TNAS则将定时器 T离超时的 时长调整为 TNAS, 或者将定时器 T计时时长直接调整为 T+ TNAS ; 如果大于或 刚好等于 TNAS则可继续监控定时器。在收到监测模块三发送为无 NAS信令数据 指示消息时, 定时器监控模块判断定时器是否超时, 如超时, 则向执行单元 M3发送省电执行命令; 如未超时, 则可继续监控定时器。
上述实施例中的移动终端数据业务节电装置适用于各种可以通过无线网 络开展业务的移动终端设备, 如手机、 手提电脑、 掌上 PC等。
通过以上的实施方式以及实施例的描述, 本领域的技术人员可以清楚地 了解到本发明可借助软件加必需的通用硬件平台的方式来实现, 当然也可以 通过硬件, 但很多情况下前者是更佳的实施方式。 基于这样的理解, 本发明 的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式 体现出来, 该软件产品存储在一个存储介质中, 包括若干指令用以使得一台 终端设备执行本发明各个实施例所述的方法。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的普 通技术人员来说, 在不脱离本发明原理的前提下, 还可以作出若干改进和润 饰, 这些改进和润饰也应视为本发明的保护范围。
