在本实施例中, 多模终端执行的网络业务包括但不限于: 彩信、 在线听歌、 在线 阅读、 网络游戏、 网页浏览、 视频通话、 即时通讯 (例如, QQ、 飞信等) 等。 多模终 端的不同业务对应着不同的功耗值, 比如: 视频通话、 网络游戏等的功耗就比较大, 而在线听歌、 网页浏览等也属于网络交互的亮屏操作, 功耗也比较大, 而 QQ和飞信, 则是属于可以后台运行, 功耗较小, 用户可能长时间开启的业务。 检测模块 20设置为检测多模终端当前环境中各网络的当前信号强度。 在本实施例中多模终端可以是包括多种网络模式的移动终端, 例如, TD 网络、 LTE网络以及 EDGE网络和 WIFI网络, 在某些环境中, 可能上述四个网络信号有强 有弱, 因此, 由检测模块 20检测获取不同网络信号强度。 当前功耗获取模块 40, 设置为获取多模终端当前执行所述网络业务的功耗信息。 网络选择模块 30与业务选择模块 10、检测模块 20和当前功耗获取模块 40耦合, 设置为根据预先设置的各个网络的信号强度、 业务类型与功耗参考值的对应关系, 当 前功耗获取模块 40获取的功耗信息, 检测模块 20检测到的各网络的当前信号强度和 业务选择模块 10获取的业务类型, 为多模终端选择驻留的网络, 其中, 选择的网络为 当前信号强度能够保证所述网络业务执行的网络中, 与当前信号强度和业务类型对应 的功耗参考值最低的网络。 在实际应用中, 对于不同业务在不同信号强度的网络下功耗不相同, 因此, 可以 预先设置各个网络的信号强度、 业务类型与功耗参考值的对应关系。 例如, 该对应关 系可以通过一个功耗状态表记录, 网络选择模块 30根据检测模块 20检测到的各网络 的当前信号强度、 业务选择模块 10获取的业务类型以及当前功耗获取模块 40获取的 功耗信息, 可以从功耗状态表中选择当前对应的功耗参考值较低的网络。 优选地, 为 了保证网络业务的执行,网络选择模块 30选择的网络的当前信号强度能够满足该网络 业务的执行。 例如, 网络选择模块 30根据检测模块 20检测到的各个网络的当前信号强度, 可 以判断是否存在当前信号强度不小于预设阈值的网络, 如果是, 则从当前信号强度不 小于预设阈值的网络中选择多模终端驻留的网络, 否则, 当前能够检测到信号的网络 中选择多模终端驻留的网络。 当然, 如果检测模块 20只能检测到一个网络的信号, 则网络选择模块 30直接选 择该网络, 或者, 如果检测模块 20检测到网络信号中, 只有一个网络的当前信号强度 不小于预设阈值, 则网络选择模块 30直接选择该网络。
在本发明实施例中, 上述多模终端驻留网络的选择装置通过获取到的各个网络的 信号强度, 根据网络业务的业务类型、 信号强度与功耗参考值的对应关系, 选择目前 功耗低且信号强度能够保证用户使用的网络驻留。 从而可以在保证用户业务执行的同 时, 最大限度的减小多模终端的功耗, 节约多模终端的电量, 延长多模终端的待机时 间。 实施例二 在实际应用中, 在同样网络同样信号强度的情况下, 如果所处环境不同, 则终端 功耗也可能产生差异。 例如, GSM网络同样信号强度时, 运行手机 QQ, 在繁华市区 和在郊外人烟稀少的地方, 功耗可能不一样, 后者更小。 所以, 上述各个网络的信号 强度、 业务类型与功耗参考值的对应关系可以根据环境动态调整。 在本实施例的一个优先实施方式中, 可以根据当前多模终端的功耗信息, 更新上 述对应关系。 因此, 如图 2所示, 本实施例的多模终端驻留网络的选择装置在实施例 一基础上增加了功耗状态维护模块 50。 功耗状态维护模块 50与当前功耗获取模块 40 耦合, 设置为更新所述对应关系中与所述多模终端当前驻留的网络的当前信号强度及 当前执行的所述网络业务的业务类型对应的功耗参考值。 即将该功耗参考值更新为与 当前功耗获取模块 40获取的功耗信息对应的功耗值。 在本实施例中, 通过动态维护不同业务的业务类型、 网络信号强度和功耗参考值 的对应关系, 可以得到多模终端处于不同环境时对应最新的针对不同业务的功耗值, 提高了网络选择的准确性。 实施例三 本实施例提供了一种多模终端, 该多模终端包括上述实施例一或实施例二所述的 装置。 在本实施例的一个优选实施方式中,可以在多模终端的 RIL(Radio interface Layer, 无线接口层) 和 Framework (框架) 之间, 增加选网模块, 通过该功能模块来实现上 述多模终端驻留网络的选择装置的功能。 以手机为例, 图 3是本实施例的优选实施方式的手机的选网模块的结构示意图, 如图 3所示, 该选网模块由业务选择模块 300、 网络信号强度获取模块 302、 当前业务 功耗获取模块 304、 功耗状态表维护模块 306和网络选择模块 308五部分组成。
其中, 业务选择模块 300设置为获取当前用户使用的业务。 例如, 在线听歌、 手 机阅读、 网络游戏、 手机上网、 手机视频、 人人网、 开心网、 新浪微博等业务。 终端 的业务对应着不同的功耗值, 比如: 手机视频、 网络游戏等的功耗就比较大, 而在线 听歌、 新浪微博等属于网络交互的亮屏操作, 功耗也比较大, 而手机 QQ和飞信, 则 可以是属于可以后台运行, 用户可能长时间开启的业务。 网络信号强度获取模块 302 (相当于上述的检测模块 20 ) 设置为读取当前环境中 各网络信号的强度。 例如, TD网络, LTE网络以及 EDGE和 WIFI网络当前的信号强 度。 在某些环境中, 可能上述四个网络信号有强有弱, 所以需要获取不同网络信号强 弱信息。 当前业务功耗获取模块 304设置为获取手机在当前网络下使用各业务的功耗值, 并计算出按照当前使用方式电池还能使用多长时间。 功耗状态表维护模块 306, 设置为维护不同业务、 网络信号强度和功耗的对应关 系。 在本实施例中, 在手机软件中内置对于不同业务、 网络信号强度和功耗的对应表 (可以称为功耗表)。在本实施例中, 系列不同业务的功耗表是动态维护的, 在终端处 于不同环境时能够得到最新的针对不同业务的功耗值, 然后对应当前网络和网络信号 强度更新该表。 网络选择模块 308, 设置为根据当前功耗值, 在网络信号强度相当的网络中, 选 取较低功耗的网络进行驻留, 以延长手机待机时间。 例如, 终端当前驻留在网络 A, 根据网络信号强度获取模块 302获取的网络信号强度确定当前环境中存在与终端当前 驻留的网络 A的信号强度相当的网络 B, 而根据功耗状态表中的记载, 网络 B在当前 信号强度下的功耗低于终端当前的功耗,则网络选择模块 308为终端选择网络 B驻留。 实施例四 本实施例提供了一种多模终端驻留网络的选择方法, 该方法可以通过上述实施例 一至实施例三所述的装置实现。 图 4是根据本发明实施例的多模终端驻留网络的选择方法的流程图,如图 4所示, 根据本发明实施例的多模终端驻留网络的选择方法主要包括以下步骤 S402 至步骤 S408。 步骤 S402, 获取多模终端当前执行的网络业务的业务类型。 步骤 S404, 检测所述多模终端当前环境中各网络的当前信号强度。
步骤 S406: 获取所述多模终端当前执行所述网络业务的功耗信息。 步骤 S408, 根据预先设置的各个网络的信号强度、 业务类型与功耗参考值的对应 关系, 获取的所述功耗信息以及检测到的所述各网络的当前信号强度和获取的所述业 务类型, 为所述多模终端选择驻留的网络, 其中, 选择的所述网络为当前信号强度能 够保证所述网络业务执行的网络中, 与当前信号强度和业务类型对应的功耗参考值最 低的网络。 在本发明实施例中, 上述多模终端驻留网络的选择装置通过获取到的各个网络的 信号强度, 根据网络业务的业务类型、 信号强度与功耗参考值的对应关系, 选择目前 功耗低且信号强度能够保证用户使用的网络驻留。 从而可以在保证用户业务执行的同 时, 最大限度的减小多模终端的功耗, 节约多模终端的电量, 延长多模终端的待机时 间。 在本实施例的一个优选实施方式中, 为所述多模终端选择驻留的网络可以包括: 如果检测到多个网络的信号, 且所述多个网络的当前信号强度均小于阈值, 则将所述 多个网络作为候选网络, 从所述候选网络中选择所述终端驻留的网络; 如果检测到多 个网络的信号, 且其中所述多个网络中存在当前信号强度不小于所述阈值的网络, 则 将所述当前信号强度不小于所述阈值的网络作为候选网络, 从所述候选网络中选择所 述终端驻留的网络。 在本实施例的一个优选实施方式中, 可以通过以下方式从所述候选网络中选择所 述终端驻留的网络: 步骤 1, 查询所述对应关系, 分别获取同等信号强度下, 所述候选网络中各个网 络对应所述当前执行的网络业务的业务类型的功耗参考值 P; 步骤 2, 从所述候选网络中为所述终端选择驻留的网络, 其中, 选择的所述网络 对应的所述功耗参考值最小。 在上述优选实施方式中, 优选地, 在选网时还可以考虑业务类型对信号强度的依 赖关系。 因此, 在本实施例的一个优选实施方式中, 在从所述候选网络中为所述多模 终端选择驻留的网络之前, 所述方法还包括: 查询预先设置的业务类型与信号强度依 赖权重的对应关系, 获取与所述当前执行的网络业务的业务类型对应信号强度依赖权 重 x, 其中, 0 χ 1。 则在该优选实施方式中从所述候选网络中为所述终端选择驻留 的网络可以包括以下步骤:
( 1 )按照下面公式分别计算所述候选网络中各个网络的信号强度与功耗综合参考 值 V:
v =x*e + ( 1-x) /p, 其中, e为检测到的所述网络的当前信号强度的归一值;
(2)从所述候选网络中选择所述信号强度与功耗综合参考值最大的网络作为所述 多模终端驻留的网络。 在上述优选实施方式中, 如果所述多模终端当前执行的网络业务的业务类型为多 个, 则获取的所述信号强度信赖权重为所述多个业务类型中对应的最大信号强度信赖 权重。 在本实施例中为了动态更新功耗的对应关系, 在执行选网之前, 还可以获取所述 多模终端当前执行所述网络业务的功耗信息。 在本实施例的一个优选实施方式中, 获取所述多模终端当前执行所述网络业务的 功耗信息, 通过获取当前的预定时间段内所述多模终端的电量消耗速度, 确定所述多 模终端当前的功耗值。例如,可以通过多模终端的底层驱动代码读出当前电池电压值, 通过电压值查询放电曲线表, 可以得到电量, 通过电量消耗速度即可得出当前多模终 端的功耗。 优选地, 可以取三分钟内电流的平均值作为当前功耗值。 在获取到所述多模终端当前执行所述网络业务的功耗信息之后, 在实施例中, 优 选地, 还可以更新所述对应关系中与所述多模终端当前驻留的网络的当前信号强度及 当前执行的所述网络业务的业务类型对应的功耗。 实施例五 本实施例以手机为例来说明多模终端驻留网络的选择方法。 图 5是根据本实施例 的多模终端驻留网络的选择方法的流程图, 如图 5所示, 主要包括以下步骤: 步骤 501, 业务选择。 获取当前手机使用的业务, 如果手机同时打开了几个业务, 可以根据预先设置的各个业务的权值决定以哪个业务为主来选取网络, 其中, 实时性 越高权值就越高。 例如, 视频通话实时性高于下载任务, 因此, 视频通话的权值高于 下载任务; 步骤 502, 网络信号强度查询。 获取当前环境中存在的各个网络信号强度, 归一 化后假设为 e; 步骤 503, 底层驱动代码读出当前电池电压值;
步骤 504, 通过电压值查询放电曲线表, 可以得到电量; 步骤 505, 根据得到的电量计算当前电流; 步骤 506, 通过电量消耗速度计算当前手机的功耗, 在本实施例中取三分钟内电 流的平均值作为当前功耗值; 步骤 507, 根据当前功耗值, 动态调整功耗状态表, 由于在同样网络同样信号强 度时, 所处环境不同, 终端功耗也可能产生差异, 因此, 本实施例中获取的终端功耗 可以用作动态调整功耗状态表的参数, 比如: GSM 网络同样信号强度时, 运行手机 QQ, 在繁华市区和在郊外人烟稀少的地方, 功耗可能不一样, 后者更小; 所以, 需要 根据环境动态调整功耗表; 步骤 508, 根据网络信号强度进行判断, 判断是否仅一种网络可选, 如果是, 则 不进行选择网络操作直接退出, 反之, 则执行步骤 509; 步骤 509, 判断是否有不为弱信号的网络, 如果没有, 则只能在网络信号强度都 为弱的网络间按功耗来选取最优网络, 执行步骤 512, 如果有, 则执行步骤 510; 步骤 510, 从待选网络组合中去除弱信号网络, 进入下一步的判断; 步骤 511, 判断去除弱信号网络后待选网络中是否仅有一种网络, 如果是则直接 跳出, 否则, 为保证用户使用直接驻留信号较强的网络, 如果有两种以上网络, 则进 入下一步; 步骤 512, 查询功耗状态表, 得出同等网络信号强度下各可选网络模式对应当前 业务的功耗参考值, 归一化后假设为 p; 步骤 513, 查询当前业务对信号强度依赖的权重表 (实时性越高的业务对信号要 求越高, 比如视频通话, 权重比也就越大), 该值为百分比, 假设为 X; 如果多个业务 并存则取最大值, 即 xmax=max{xl,x2〜} ; 步骤 514, 计算信号强度与功耗综合参考值 V =xmax*e + ( 1-xmax) /p,其中 e为步 骤 502中获取的网络信号强度归一值; 步骤 515, 根据计算出的 V选择最大值 vmax进行选网。 需要说明的是, 本实施例的选网策略主要基于功耗, xmax的引入只是为了保证更 好的用户体验, 因此该值一般都较小, 这样 V主要还是由加号右半部分决定。
从以上的描述中, 可以看出, 通过上述一个或多个实施例提供的技术方案, 可以 实现移动终端根据业务功耗选网, 通过对业务、 功耗和网络信号强度的分析, 能够在 不影响用户使用的情况下, 动态的为用户选择功耗低的网络驻留, 达到延长智能手机 续航时间的目的。 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。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
