具体实施方式
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。
本发明实施例适用于各种网络，尤其适用于当今快速发展的物联网。物联网作为新兴高技术产业的重要组成部分，已被世界各国当作应对经济危机、振兴经济的重点技术之一。物联网业务可以广泛地应用到众多的行业中，包括车辆、电力、金融、环保、石油、个人与企业安防、水文、军事、消防、气象、煤炭、农业与林业、电梯等。根据专家预计，未来几年间，物联网业务将快速地进入很多行业，其用户数也将快速成长，2013年全球物联网市场规模约为3012亿美元，2014年增长至3468亿美元，物联网应用也会在若干年后成为第五代(5G)的核心应用之一，具有广阔的发展前景。物联网信息的承载主要基于有线传输(如有线宽带)、短距离无线传输(如Wi-Fi、ZigBee、RFID等)和移动互联网(如2G、3G和LTE网络等)等载体。基于移动互联网承载的物联网正在占据越来越重要的地位，其应用于不便于布线或布线成本较高以及一些特殊的场景下，比如远程物流的运输 和监控、能源“三表”的远程控制、野外设备的监控和控制、儿童及高龄老人的追踪、警察管理、追踪罪犯等场合。这些行业的物联网终端往往使用电池供电，要求终端的电池长时间不用更换(比如半年或更长的时间，越长越好)。因此，要推动基于移动互联网的物联网产业发展，必须要面对该类物联网终端的功耗挑战。以普通手机终端为例，在其电源周期中，UICC卡被终端激活使用的情况主要包括下列几种情况，例如，终端读取和存储UICC中运营商设置的配置参数，终端执行鉴权过程，终端往UICC卡写数据，终端读取存储在UICC上的用户的短消息和电话本,卡工具箱命令的使用等情况，而在其余时间，UICC是不被终端激活的，另外据业界测算；UICC产生的功耗，关闭UICC的电源情况对比不关闭UICC电源的情况，一周时间内，后者的能耗比前者多40倍左右。同时在物联网终端中，根据移动物联网应用特点以及业务模式，可以把移动物联网场景分为以下几大类：(1)固定或低移动性的物联网终端应用场景固定或低移动性的物联网设备(如三表、变压器监测终端等)，这些设备一般处于固定位置不变或移动性较小的应用场景。(2)通信时限受限与约束场景该场景指根据预先设定的特定时间间隔内收发数据和进行通信，其他时间终端处于关闭状态。物联网平台可以准许或拒绝终端设备在预设的特定时限外的业务接入。对于禁止时段，平台直接拒绝接入。利用该特征，终端设备可以在预先设定的特定时限内进行接入和通信，其他时间则处于低功耗状态。(3)只支持主叫内业务场景，物联网设备只支持主叫内业务场景，该场景要求物联网终端设备进行周期或非周期性向平台上报信息，而不接收从平台下发的指示或信息。(4)非频繁的被叫业务场景对于非频繁的被叫业务场景，终端接受和响应寻呼的概率很低。从上述可以看出多数物联网终端使用时在多数时间处于不活跃状态，基于此本发明实施例提出了一种降低终端功耗的方法，以满足日益增长的物联网应用的需求，在UICC处于非激活状态时，通过移除UICC的电源，以用来降低UICC的功耗，从而降低终端的能耗。从而提高移动物联网终端电池的使用时间。
实现方法是通过修改和优化终端与UICC通信协议，在不改变网 络侧和终端硬件的前提下，降低UICC的功耗，从而降低终端的平均功耗，以达到提高移动物联网终端电池的使用时间的目的。
图1为本发明实施例提供的降低终端功耗的方法实施例一的流程示意图，如图1所示，本实施例的执行主体为UICC，所述方法包括：
步骤101：接收终端的挂起命令。
在本步骤中，UICC接收终端发送的挂起命令，其中，挂起命令包括：终端给出的建议的最大挂起时间长度。终端在检测到UICC符合挂起条件时，会给UICC发送挂起命令，挂起命令中包括终端给出的最大挂起长度。UICC接收到该挂起命令后，执行后续的挂起操作。
步骤102：将UICC的状态信息存储。
可选的，该方法还包括向终端发送挂起响应命令，其中，挂起响应命令包括挂起时间长度和恢复UICC的状态信息的关键字。
在本步骤中，UICC接收到终端的挂起命令后，将当前UICC的状态信息进行存储，该UICC的状态信息即为待以后恢复的状态信息，具体存储到UICC的非易失存储器(Non-Volatile Memory)中，同时向终端发送挂起响应命令，挂起响应命令包括挂起时间长度和恢复所述状态信息的关键字，即UICC最终确定的挂起时间长度(终端和UICC交互确定挂起的时间长度)和恢复信息关键字。通过上述挂起响应命令将相应恢复信息关键字的值传送给终端，由终端存储于终端的存储器中，用于恢复UICC状态时的比较，具体的，恢复时将该关键字和UICC非易失存储器上存储的UICC状态信息条目进行匹配，如果匹配，则按照该关键字进行对应的UICC状态信息恢复UICC到以前的状态。此时，终端控制UICC的电源关闭，UICC进入挂起状态。
本实施例的降低终端功耗的方法，UICC接收到终端发送的挂起命令后，将UICC的状态信息进行存储，从而终端进一步控制UICC的电源关闭，UICC进入挂起状态，且UICC在恢复时可以根据存储 的UICC状态信息的相关内容进行恢复。该方法在不改变网络侧和终端硬件结构的前提下，降低UICC的功耗，从而降低终端的平均功耗，扩大了降低终端功耗方法的应用场景，提高降低功耗的能力。
可选的，所述接收终端的挂起命令之前还包括：
修改UICC服务表，使所述UICC服务表增加指示挂起命令和恢复命令的指示信息；
向所述终端发送所述修改后的UICC服务表。
具体的，修改UICC服务表，使UICC服务表使用一个比特指示UICC挂起命令和使用一个比特指示UICC恢复命令；
可选的，所述修改UICC服务表为：在所述UICC服务表后增加第一指示信息和第二指示信息；其中，所述第一指示信息指示UICC挂起命令，所述第二指示信息指示UICC恢复命令。
具体的，以UICC的一个应用USIM卡为例进行说明。修改结果如表1所示，表1为修改后的USIM服务表(USIM Service Table)，参见3GPP TS 31.102(8.40版本)，可以看出，在表1最后增加了如下字段：

表1
图2为修改UICC服务表后终端和UICC的交互流程示意图，如图2所示，该流程包括下列步骤：
步骤201：UICC初始化。
步骤202：UICC向终端发送修改后的UICC服务表。
UICC(USIM应用)向终端指示它的SIM Service Table支持“Additional TERMINAL PROFILE。
步骤203：终端获取UICC发送的修改后的UICC服务表。
步骤204：终端根据修改后的UICC服务表判断UICC是否支持挂起命令和恢复命令。
步骤205：UICC接收到profile download指令，判断终端是否支持挂起UICC命令和恢复UICC命令。
具体的，终端通过修改后的USIM服务表检查UICC是否支持挂 起UICC命令和恢复UICC命令；终端如果发现UICC支持，同时自己也支持挂起UICC命令和恢复UICC命令；则执行Profile download过程(终端发送profile download指令给UICC)，向UICC表明自己也支持挂起UICC命令和恢复UICC命令；如果自己不支持挂起UICC命令和恢复UICC命令；则执行Profile download过程(终端发送profile download指令给UICC)，向UICC表明自己不支持挂起UICC命令和恢复UICC命令；
否则如果终端发现UICC不支持，则执行Profile download过程(终端发送profile download指令给UICC)，后续不向UICC发起挂起UICC命令和恢复UICC命令。
步骤206：当UICC和终端均支持挂起命令和恢复命令时，进行后续的挂起操作和恢复操作。
如果终端支持挂起UICC命令和恢复UICC命令，而且自己也支持挂起UICC命令和恢复UICC命令；后续可以进行挂起UICC命令和恢复UICC命令操作，否则不能进行挂起UICC命令和恢复UICC命令的操作。
可选的，所述UICC的状态信息包括：

步骤302：接收UICC发送的挂起响应命令。
其中，挂起响应命令包括挂起时间长度和恢复UICC的状态信息的关键字。
所述UICC的状态信息包括：所述UICC的每个逻辑通道选择的网络接入应用NAA的状态、所述UICC的每个网络接入应用的安全条件、所述UICC的每个逻辑通道选择的基本文件和相应的记录和/或所述UICC应用工具箱的状态。
在本步骤中，终端接收UICC发送的挂起响应命令，该命令包括了UICC确定的挂起时间长度和恢复UICC状态信息的关键字。终端接收该关键字，并将挂起响应命令中的恢复UICC状态信息的关键字存储，以便在恢复时利用该关键字进行比较。
步骤303：根据挂起响应命令关闭UICC电源。
可选地，根据挂起响应命令中的挂起时间长度，确定关闭UICC电源的时间长度。
本实施例的降低终端功耗的方法，终端通过检测到UICC符合挂起条件时，向UICC发送挂起命令，并接收UICC发送的挂起响应命令，存储挂起响应命令中的恢复状态信息的关键字，以便在后续恢复UICC的状态时利用该关键字进行比较；关闭UICC电源，并根据挂起响应命令中的挂起时间长度来确定关闭UICC电源的时长。

步骤504：如果恢复命令中的恢复UICC的状态信息的关键字和UICC的状态信息匹配，则按照关键字对应的UICC的状态信息进行恢复，并向终端发送恢复成功的响应信息。
在本步骤中，如果上述恢复UICC的状态信息的关键字和UICC的状态信息匹配，则UICC按照关键字对应的UICC的状态信息将UICC恢复到以前的状态，并向终端发送恢复成功的响应信息；否则如果不匹配，恢复UICC失败，继续进入挂起状态，并向终端发送恢复失败的响应信息。
