  • the power consumption of the UE is also different for different situations. For example, UEs that support multi-RAT (Radio Access Technology) have different operating power consumption under different RATs due to device power consumption differences. In addition, since the 2G (the 2nd generation) mode radio frequency circuit consumes less power than the 3G (the 3rd generation) mode, the UE consumes power in the 2G network to the 3G network.

For example, the voice service of 4.75 kbps is relatively 12.2 kbps voice service, and the former saves power compared with the latter.

Description

管理电源的方法、 终端设备、 网络侧设备和通信系统 技术领域
本发明实施例涉及无线通信领域，并且更具体地，涉及管理电源的方法、 终端设备、 网络侧设备和通信系统。 背景技术
作为用户体验的一个重要评估维度， 运营商十分重视网络下 UE ( User Equipment; 用户设备）的待机和通话时间。 随着无线通信技术向宽带化演 进和智能终端的普及， UE的耗电问题越来越严重。
针对不同的情况， UE 的耗电量也有差异。 例如， 支持多 RAT ( Radio Access Technology;无线接入技术 )的 UE由于器件功耗差异，在不同的 RAT 下工作功耗有差异。 另外， 因为 2G ( the 2nd Generation; 第二代）模式的射 频电路功耗小于 3G ( the 3rd Generation; 第三代 )模式， 所以 UE在 2G网 络下通话功耗 于 3G网络。 此外， 在同一个 RAT内部， 不同的无线资源分 配策略下， 终端的耗电量也会不同， 如 4.75kbps 的语音业务相对 12.2kbps 语音业务， 前者比后者省电。 而且， UE 中有的应用比较费电， 而有的应用 则比较省电。
这些耗电量的差异化导致终端电源的利用效率降低，缩短了终端待机时 间， 也影响终端电池的寿命。 发明内容

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。
本发明的技术方案， 可以应用于各种通信系统， 例如： GSM, 码分多址
( CDMA, Code Division Multiple Access ) 系统， 宽带码分多址（ WCDMA,
Wideband Code Division Multiple Access Wireless ) , 通用分组无线业务 ( GPRS , General Packet Radio Service ) , 长期演进 （LTE , Long Term
Evolution )等。
移动终端 （ Mobile Terminal ) , 也可称之为移动用户 （ UE , User
Equipment ),移动用户设备等，可以经无线接入网（例如， RAN, Radio Access Network )与一个或多个核心网进行通信， 移动终端可以是移动终端， 如移 动电话（或称为"蜂窝"电话）和具有移动终端的计算机， 例如， 可以是便携 式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置， 它们与无线接入 网交换语言和 /或数据。
基站，可以是 GSM或 CDMA中的基站（ BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站（ NodeB ),还可以是 LTE中的演进型基站（ eNB 或 e-NodeB, evolutional Node B ), 本发明并不限定。
基站控制器，可以是 GSM或 CDMA中的基站控制器（ BSC, Base Station Controller ), 也可以是 WCDMA中的无线网络控制器（ RNC, Radio Network Controller ) , 本发明并不限定。 图 1是根据本发明实施例的管理电源的方法的示意流程图。 图 1的方法 可以由终端设备 (例如， UE )执行。
在 101 , 根据剩余电量或终端设置确定终端能耗等级， 其中终端能耗等 级为至少两个耗电等级之一。
因此， 本发明实施例对于终端电源的不同剩余电量或终端设置， 采用不 同的耗电等级， 从而能够适应差异化的耗电需求， 提高了终端电源的利用效 率。
本发明实施例的终端能耗等级表征终端对电源节能要求的级别。例如级 别越高可表示省电需求越优先。 终端能耗等级可包括两个等级： 不省电和省 电。 也可以扩展到更多种省电模式， 如： 不省电、 一般省电、 省电优先。 或 者按照耗电模式分为高性能（高耗电）、 平衡耗电 （中耗电）、 高节电 （低耗 电）等。
这里给出的耗电等级的例子不对本发明实施例的范围构成限制。在本发 明实施例的范围内， 可以采用更精细的级别， 也可以采用其他级别模式。
本发明实施例可以按照剩余电量划分耗电等级。每个耗电等级针对于一 个剩余电量区间， 即具有该区间下端的第一门限和上端的第二门限。 图 2是 根据本发明实施例的终端能耗等级的一个例子的示意图。 如图 2所示， 剩余 电量 0-30%对应于耗电等级 3 , 如 "省电优先"。 剩余电量 30%-60%对应于 耗电等级 2, 即 "一般省电"。剩余电量 60%-100%对应于耗电等级 1 , 即 "不 省电"。 图 2 中的门限取值只是示例性的， 不对本发明实施例构成限制。 在 本发明实施例的范围内， 可使用其他门限值。
在图 1的 101中，在剩余电量小于第一门限或者剩余电量大于第二门限 时， 改变终端能耗等级。 第一门限等于或小于第二门限。 例如， 假设目前终 端能耗等级为 2, 第一门限为 30%, 第二门限为 60%。 当剩余电量降至 30% 以下时， 则终端能耗等级变为 3; 而当剩余电量升至 60%以上时， 终端能耗 等级变为 1。
可以在终端中提供剩余电量的相关参数（例如， 上述第一门限或第二门 限）的设置选项， 使得用户能够根据需要设置或调整改变终端能耗等级的门 限值。 终端接收对第一门限或第二门限的用户设置。
终端可以周期性地执行图 1的电源管理方法， 以实时地确定终端的能耗 等级。 本发明实施例也可以按照终端设置确定耗电等级。 例如， 终端可以提供 各个终端能耗等级的相应设置选项， 以供用户根据需要进行选择。 终端设置 可以是用户对终端能耗等级的选择， 并根据用户对终端能耗等级的选择确定 终端能耗等级。 此时可不考虑剩余电量， 只根据用户的选择来指定终端能耗 等级， 从而能够优先满足用户的需求。 例如， 当用户希望让终端的待机时间 更长时， 用户可以选择耗电量最小的终端能耗等级， 而不考虑终端的剩余电 量。
另外， 终端设置也可将终端能耗等级与应用相关联。 此时可根据与终端 能耗等级相关联的应用的运行状态确定终端能耗等级。 某些应用 （或者应用 的某些功能）可能相对比较耗电， 或者希望能尽快完成或希望优先保证运行 质量而不考虑耗电情况， 例如高运算量的应用、 高速下载应用等， 更适合在 终端能耗等级 1 ( "不省电"）之下运行。 处于终端能耗等级 2或 3的终端启 动这类应用 （或者启动应用中的某些功能）时， 可将终端能耗等级变为 1以 适应这类应用， 在关闭这类应用 （或者关闭应用中的某些功能）时， 则将终 端能耗等级变为相对省电的等级。
应用中也可以具有与终端能耗等级相关联的选项，使得用户可以选择该 应用的耗电等级。 当该应用开启时， 将终端能耗等级设置为所选择的耗电等 级。 当该应用关闭时， 可以恢复为开启前的终端能耗等级， 也可以按照本发 明实施例的其他方式重新确定终端能耗等级。
本发明实施例也可综合考虑剩余电量和终端设置来确定合适的终端能 耗等级， 从而提供了差异化的电源管理方案， 提高了终端电源的利用效率。
在维护终端能耗等级的基础上， 可进一步结合网络侧的相关耗电等级， 提高系统内电源的利用效率。
上面描述了终端侧设置耗电等级的例子。 本发明实施例的网络侧（例如 基站、 基站控制器等）也可以设置相应的耗电等级（小区耗电级别）。 图 3 是根据本发明实施例的管理电源的方法的示意流程图。 图 3的方法由网络侧 设备（例如， 基站、 RNC等）执行。
在 301 , 确定小区耗电级别， 小区耗电级别用于指示终端在小区中的耗 电量。
在 302, 向终端发送携带小区耗电级别的信息的小区广播消息或专用信 令。 这样， 本发明实施例的网络侧能够向终端下发自己的小区耗电级别， 从 而使得终端能够根据网络侧的小区耗电级别进行匹配的操作，提高系统电源 的利用效率。
例如， 终端能够根据小区耗电级别选择合适的驻留小区。 图 4是根据本 发明实施例的管理电源的方法的示意流程图。图 4的方法可以由终端设 例 如， UE )执行。
在 401 , 接收携带小区耗电级别的信息的小区广播消息或专用信令， 该 小区耗电级别用于指示终端在小区中的耗电等级。
在 402, 基于小区耗电级别选择驻留小区。
这样， 本发明实施例的终端能够接收网络侧下发的小区耗电级别， 从而 使得终端能够根据网络侧的小区耗电级别选择合适的驻留小区，提高系统电 源的利用效率。
例如，终端可选择具有耗电较少的小区耗电级别的小区，作为驻留小区， 以增加待机时间。 另外， 如果终端同时能够执行图 1所述的方法， 则可以综 合考虑自身的终端能耗等级和小区下发的小区耗电级别，选择匹配的小区作 为驻留小区， 从而兼顾待机时间和业务运行的质量。
图 5是根据本发明实施例的选择驻留小区的过程的示意流程图。 图 5的 过程涉及终端 UE和有可能作为 UE的驻留小区的多个小区 1、 2 n ( n 为正整数） 的网络侧设备（例如， 基站或 RNC, 为筒洁起见， 图 5 中以小 区 1-n分别指代它们的网络侧设备）。
如图 5所示， 在 501 , 各个小区 1-n的网络侧设备确定各自的小区耗电 级别。 小区耗电级别可以与上述终端能耗等级对应， 例如包括高耗电、 中耗 电和低耗电， 也可以有所不同。 各个小区可根据小区的无线接入技术种类或 者控制终端的无线参数， 确定小区耗电级别。 例如， 3G小区可以比 2G小区 具有更加耗电的小区耗电级别。
在 502, 小区的网络侧设备将各自的小区耗电级别通知给 UE。 可通过 小区广播消息或专用信令携带有关小区耗电级别的信息。
在 503 , UE维护自身的终端能耗等级。 例如， UE可按照图 1的方法， 根据剩余电量或终端设置， 确定终端能耗等级。
在 504, UE在得到网络侧发送的小区耗电级别以及自身的终端能耗等 级之后， 选择小区耗电级别和终端能耗等级匹配的小区作为驻留小区。 UE可优先选择小区耗电级别等于或小于终端能耗等级的小区作为驻留 小区。 例如， UE可按照以下优先级选择驻留小区： 优先选择小区耗电级别 等于终端能耗等级的小区， 其次选择小区耗电级别小于终端能耗等级的小 区， 最后选择小区耗电级别大于终端能耗等级的小区。
UE 可以在小区选择或小区重选的过程中， 基于所在区域若干小区广播 的小区耗电级别以及终端自身的耗电等级选择驻留小区。
应注意， 虽然图 5中 503显示为在 501和 502之后执行， 但是本发明实 施例不限于此。 503可在 501或 502之前执行， 也可以与 501或 502并行执 行。 这些变化均落入本发明实施例的范围内。
终端在确定自身的终端能耗等级之后，也可以向网络侧上报该终端能耗 等级， 从而使得网络侧能够进行匹配的操作， 提高系统电源的利用效率。
例如， 网络侧在进行资源分配时， 可根据终端上报的能耗等级选择资源 分配方案。 图 6是根据本发明实施例的管理电源的方法的示意流程图。 图 6 的方法由网络侧设备（例如， 基站、 RNC等）执行。
在 601 , 接收终端上报的终端能耗等级， 终端能耗等级为终端的至少两 个耗电等级之一。
在 602, 基于终端能耗等级选择资源分配方案。
这样， 本发明实施例的网络侧设备接收终端的终端能耗等级， 选择适合 于终端能耗等级的资源分配方案， 提高了系统电源的利用效率。
例如， 网络侧可以优先选择符合终端能耗等级的无线参数、 信道配置、 特性配置或其他参数。
在根据终端上报的能耗等级选择资源分配方案时， 网络侧也可以综合考 虑各个资源分配方案相应的资源耗电等级。 图 7是根据本发明实施例的选择 资源分配方案的过程的示意流程图。 图 7的过程涉及终端 UE和小区的网络 侧设备 (基站或 RNC )。
如图 7所示， 在 701 , 小区确定各个资源分配方案的资源耗电等级。 资 源耗电等级可以与上述终端能耗等级对应， 例如包括高耗电、 中耗电和低耗 电， 也可以有所不同。 小区根据资源分配方案的耗电需求确定其耗电等级。 例如， 对于语音业务， 12.2kbps的速率方案比 4.75kbps的速率方案具有更耗 电的资源耗电等级。
在 702 , UE维护自身的终端能耗等级。 例如， UE可按照图 1的方法， 根据剩余电量或终端设置， 确定终端能耗等级。
在 703 , UE将终端能耗等级上报给网络侧。
在 704, 网络侧在为终端分配无线资源时， 选择资源耗电等级与终端能 耗等级匹配的资源分配方案。
例如， 网络侧可优先选择资源耗电等级等于或小于终端能耗等级的资源 分配方案。 例如， 网络侧可按照以下优先级选择资源分配方案： 优先选择资 源耗电等级等于终端能耗等级的资源分配方案， 其次选择资源耗电等级小于 终端能耗等级的资源分配方案， 最后选择资源耗电等级大于终端能耗等级的 资源分配方案。
应注意， 虽然图 7中 701显示为在 702和 703之前执行， 但是本发明实 施例不限于此。 701可在 702或 703之后执行， 也可以与 702或 703并行执 行。 这些变化均落入本发明实施例的范围内。
下面结合图 2、 图 5和图 7的例子描述本发明实施例的一个具体应用实 例。 应注意， 此例子只是为了更好地表述本发明实施例的概念， 而非要限制 本发明实施例的范围。
如果终端剩余电量不足 30%, 终端能耗等级为等级 3 ( "节电优先"）， 则连接态无线资源分配时只给终端建立 4.75kbps的低速语音业务，空闲态的 UE优先选择驻留在 2G网络中。 如果剩余电量超过 60%, 则终端能耗等级 为 1 , 优先给终端建立 12.2kbps甚至更高速率的语音业务， 空闲态可以驻留 在 3G网络中 （2G网络相对 3G网络节电）。
图 8是根据本发明实施例的终端设备的示意框图。 如图 8所示， 终端设 备包括参数确定单元 801和等级确定单元 802。
参数确定单元 801用于确定剩余电量或终端设置。
等级确定单元 802用于根据剩余电量或终端设置确定终端能耗等级， 其 中终端能耗等级为至少两个耗电等级之一。
因此， 本发明实施例对于终端电源的不同剩余电量或终端设置， 采用不 同的耗电等级， 从而能够适应差异化的耗电需求， 提高了终端电源的利用效 率。
图 8的终端设备的一个例子是 UE, 并且可执行图 1的各个过程。
图 9是根据本发明另一实施例的终端设备的示意框图。 在图 9中， 与图
8相同或相似的部分用相同的附图标记表示， 并适当省略其详细描述。 图 9中的等级确定单元 802可在剩余电量小于第一门限或者剩余电量大 于第二门限时， 改变终端能耗等级。 图 9的终端设备包括可选的参数接收单 元 901 , 用于接收对第一门限或第二门限的参数设置。
可替换地，等级确定单元 802根据用户对终端能耗等级的选择确定终端 能耗等级， 或者根据与终端能耗等级相关联的应用的运行状态确定终端能耗 等级。此时终端可具有各个终端能耗等级的相应选项，以供用户选择或设置， 并由参数接收单元 901接收用户对终端能耗等级的选择。
另外， 终端可以提供各个应用的终端能耗等级选项， 以供用户选择或设 置， 并由参数接收单元 901接收用户对应用的相应设置。
此外， 图 9的终端设备还可以包括上 ·艮单元 902, 用于向网络侧上 ·艮终 端能耗等级。 例如， 使得网络侧能够根据所上报的终端能耗等级选择合适的 资源分配方案。
图 9的终端设备的一个例子是 UE, 并且可执行图 5和图 7中涉及终端 UE的各个过程。
图 10是根据本发明另一实施例的终端设备的示意框图。 图 10的终端设 备包括接收单元 1001和选择单元 1002。
接收单元 1001用于接收携带小区耗电级别的信息的小区广播消息或专 用信令， 小区耗电级别用于指示终端在小区中的耗电等级。 选择单元 1002 用于基于小区耗电级别选择驻留小区。
这样， 本发明实施例的终端能够接收网络侧下发的小区耗电级别， 从而 使得终端能够根据网络侧的小区耗电级别选择合适的驻留小区，提高系统电 源的利用效率。
图 10的终端设备的一个例子是 UE, 并且可执行图 4的各个过程。
图 11是根据本发明另一实施例的终端设备的示意框图。 在图 11中， 与 图 10相同或相似的部分用相同的附图标记表示， 并适当省略其详细描述。
除了图 10中的部件之外， 图 11的终端设备还包括等级确定单元 1101。 等级确定单元 1101类似于图 8的等级确定单元 802,用于根据剩余电量或终 端设置确定终端能耗等级， 其中终端能耗等级为至少两个耗电等级之一。
此时， 选择单元 1002选择小区耗电级别和终端能耗等级匹配的小区作 为驻留小区。
下面描述相应的网络侧设备。 图 12是根据本发明一个实施例的网络侧 设备的示意框图。 图 12 的网络侧设备包括等级确定单元 1201 和消息单元 1202。
等级确定单元 1201用于确定小区耗电级别， 小区耗电级别用于指示终 端在小区中的耗电量。
消息单元 1202用于向终端发送携带小区耗电级别的信息的小区广播消 息或专用信令。
这样， 本发明实施例的网络侧能够向终端下发自己的小区耗电级别， 从 而使得终端能够根据网络侧的小区耗电级别进行匹配的操作，提高系统电源 的利用效率。
图 12的网络侧设备的例子是基站或 RNC,并且可执行图 3的各个过程。 例如， 等级确定单元 1201可根据小区的无线接入技术种类或者控制终 端的无线参数， 确定小区耗电级别。
