Description

控制供电的方法和无线终端
本申请要求于2013年10月30日提交中国专利局、申请号为201310529506.7、发明名称为“控制供电的方法和无线终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信应用领域，特别涉及无线终端供电的方法和无线终端。
背景技术
当无线终端与网络侧设备通信时，无线终端可以在空闲状态和连接状态之间进行切换。为了减少无线终端的电能消耗，当无线终端处于空闲状态时，无线终端常常采用不连续接收DRX(Discontinuous Reception)的方式监听寻呼信道，采用不连续发送DTX(Discontinuous Transmission)的方式向网络侧设备发送数据。
图1所示为无线终端的DRX状态图，在一个DRX周期中，无线终端有两种状态：休眠状态和唤醒状态。无线终端仅在唤醒状态时接收网络侧设备发送的消息(例如寻呼消息)，当无线终端处于DRX周期中的休眠状态时，不接收网络侧设备发送的消息，无线终端的部分电路此时处于低功耗的状态。类似的，一个DTX周期中，无线终端也有两种状态：休眠状态和唤醒状态，无线终端仅在唤醒状态时向网络侧设备发送消息(例如语音消息、或者寻呼网络状态的消息)，当无线终端处于DTX周期中的休眠状态时，不向网络侧发送消息，无线终端的部分电路此时处于低功耗的状态。
现有技术中，当无线终端处于休眠状态时，无线终端中的部分电路处于低功耗状态，但是射频电路是一直被供电的。如果射频电路长期被供电，射频电路的可靠性和使用寿命会受到明显影响，而且也会浪费部分电能。

如图4所示，为本发明实施例中通信单元的结构示意图，该通信单元包括：电源控制电路、射频电路、基带控制电路、天线和开关电路。图4中的电路之间连接线有两种，其中较粗的连接线表示的是供电关系，较细的连接线表示的是信号传输关系。
所述射频电路，用于接收所述天线发送的下行模拟信号，转换成下行数字信号发送给所述基带控制电路处理，和接收所述基带控制电路发送的上行数字信号，转换成上行模拟信号并发送给所述天线发射。需要说明的是，此处的“上行数字信号”和“上行模拟信号”分别指的是无线终端向网络侧设备发送的数字信号和模拟信号，“下行数字信号”和“下行模拟信号”分别指的是网络侧设备向无线终端发送的数字信号和模拟信号。
所述电源处理电路，用于为基带控制电路供电，并接收所述基带控制电路发送的电源控制信号，根据所述电源控制信号对射频电路供电。图4中省略了电源处理电路与图3中的电源之间的关系，可以理解，图4中的电源处理电路可以包含电源和对电源提供的电能进行处理和分配的电路；也可以只包含和对电源提供的电能进行处理和分配的电路。
所述开关电路位于所述电源处理电路到射频电路的供电线路上，并用于接收所述基带控制电路的断开命令，根据所述断开命令，断开对所述射频电路的部分或全部电路的供电线路；其中，所述休眠状态包括以下至少一个：不连续发送DTX周期中的休眠状态，和不连续接收DRX周期中的休眠状态。其中，DTX周期的数目为至少一个，和DRX周期的数目为至少一个。采用DRX或者DTX周期中至少一个休眠状态部分时段或全部时段，对射频电路的部分或全部电路的供电，其断电的时段更加灵活多样。
所述基带控制电路，用于接收所述射频电路发送的所述下行数字信号并处理，生成所述上行数字信号并向所述射频电路发送，向所述电源处理电路发送电源控制信号；并在所述无线终端处于休眠状态的部分时段或全部时段开始时、并向所述开关电路发送断开命令。
需要说明的是，具体实现时，当确定无线终端进入省电功能(例如无线终 端接收到用户输入进入省电模式的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到当前处于设定的时间段或检测到无线终端位于设定的地点设定的地点，无线终端开机后自动执行等等)，基带控制电路的供电可以一直维持，以基带控制电路持续的计时，并在给射频电路的全部或者部分电路停止供电的时段(即：无线终端处于休眠状态的部分时段或全部时段)开始时，就向所述开关电路发送断开命令，所述开关电路收到断开命令后立即断开该开关电路所在的供电线路，以切断射频电路的全部或部分供电，此处的开关电路收到断开命令并执行断开的整个响应时间，相对于给射频电路的全部或者部分电路停止供电的整个时段很短，因此该响应时间可以忽略不计。显而易见的，停止对所述射频电路的部分或全部电路的供电的时间，不大于所述无线终端处于休眠状态的时间
停止对射频电路的全部或者部分电路进行供电的时段，具体可以包括以下八种时段：
(a)在无线终端的DTX周期中的休眠时段的全部时段；
(b)在无线终端的DTX周期中的休眠时段的部分时段；
(c)在无线终端的DRX周期中的休眠时段的全部时段；
(d)在无线终端的DRX周期中的休眠时段的部分时段；
(e)(a)和(c)所述的时段；
(f)(a)和(d)所述的时段；
(g)(b)和(c)所述的时段；
(h)(b)和(c)所述的时段。
其中，DTX周期中休眠时段的全部时段是指，DTX周期中的所有休眠时段，DTX周期的数目为至少一个。DTX周期中的休眠时段的部分时段是指，DTX 周期中休眠时段的一部分，DTX周期的数目为至少一个，例如：一个DTX周期中休眠时段的前二分之一，或者所有DTX周期中休眠时段的前三分之一等。
其中，DRX周期中休眠时段的全部时段是指，DRX周期中的所有休眠时段，DRX周期的数目为至少一个。DRX周期中的休眠时段的部分时段是指，DRX周期中休眠时段的一部分，DRX周期的数目为至少一个，例如：一个DRX周期中休眠时段的前二分之一，或者所有DRX周期中休眠时段的前三分之一等。
可选的，本发明实施例中，在上述八种时段停止对射频电路的全部或者部分电路进行供电，指的是，仅在这八种时段停止对射频电路的全部或者部分电路进行供电，以(a)为例，仅仅在无线终端的DTX周期中的休眠时段的全部时段，停止对射频电路的全部或者部分电路进行供电，当所述基带控制电路在DTX周期的休眠时段的全部时段之外的其他所有时段，恢复对射频电路的全部电路进行供电。其他的(b)-(h)的情况类似，此处不再赘述。恢复对射频电路的全部电路进行供电，具体可以由基带控制电路，在停止对所述无线终端中的射频电路的全部或部分电路的供电的时段结束时，向已收到了断开命令的开关电路发送连通命令，以连通之前断开的供电线路。由于开关电路从收到连通命令到执行连通的整个过程所用的响应时间、相对于停止对射频电路的全部或部分电路的供电的时段、以及维持对射频电路的全部电路供电的时段很短，因此该响应时间可以忽略不计。
可以理解，停止对射频电路的全部或者部分电路进行供电的时段，可以不仅仅只包含一个持续的时间段，例如一个DRX周期中的休眠时段的前二分之一、或者前三分之一；还可以包含多个非连续的时间段，例如为每个DRX周期中的全部休眠时段，或者为每个DTX周期中的休眠时段的前二分之一，或者是(a)-(h)中的情况的组合。
如果停止对射频电路的全部或者部分电路进行供电的时段是(e)--(h)的情况，当无线终端当前既有不连续发送，也有不连续接收，可能会存在一种特殊的情况，即当前虽然处于DRX的休眠时段，但是不处于DTX的休眠时段，或者当前虽然处于DTX的休眠时段，但是不处于DRX的休眠时段，为了保证不连续发送或不连续接收的正常进行，需要维持对射频电路的相关电路的供电，为了简化设计，可以设计为：只有当前既在处于DTX的休眠时段、同时也处于DRX的休眠时段时，才停止对射频电路的全部或者部分电路进行供电。换句话说，(e)中“(a)和(c)”的含义是(a)与(c)同时满足。(f)--(h)的含义也类似。
本发明另一实施例还提供一种采用上述通信单元的无线终端，无线终端除了包含上述通信单元，还可以根据需要包含例如图3所示的其他单元，通信单元与其他单元的数据传输或连接关系，可以参考对图3的描述，此处不再重复。
如果无线终端采用本实施例提供的通信单元，可以实现在无线终端处于休眠状态时，对不需要全部的射频电路进行供电，从而减少了无线终端的电能消耗、延长了待机时间，同时，由于射频电路在长期供电的情况下，可靠性会逐渐降低，因此本发明实施例也延长了无线终端中射频电路的使用寿命。
可选的，所述不连续发送DTX周期中的休眠状态，具体为：全部DTX周期中的休眠状态，或者部分DTX周期中的休眠状态；所述不连续接收DRX周期中的休眠状态，具体为：全部DRX周期中的休眠状态，或者部分DRX周期中的休眠状态。
这意味着，在前述的(a)-(h)的停止供电时段的基础上进一步细化，可以在以下8种时段中停止对所述射频电路的部分或全部电路的供电：
(1)在无线终端的每个DTX周期中的休眠时段中的全部或部分时段；
(2)在无线终端的部分DTX周期中的休眠时段中的全部或部分时段；
(3)在无线终端的每个DRX周期中的休眠时段中的全部或部分时段；
(4)在无线终端的部分DRX周期中的休眠时段中的全部或部分时段；
(5)在(1)和(3)所述的时段；
(6)在(2)和(4)所述的时段；
(7)在(1)和(4)所述的时段；
(8)在(2)和(3)所述的时段。
其中，(2)中所述的部分DTX周期和(4)中所述的部分DTX周期的选择方式有多种，例如可以每两个连续的周期中选择一个，或每三个连续的周期中选择一个或两个，或者每四个连续的周期中选择前两个等。选择时可以基于算法复杂程度和省电效率等选择合适的“部分周期”，其选择方式不构成对本发明的限定。可以理解，断电的总时间越长，省电的效果越明显，但是省电的总时间较少时，虽然省电效果较弱，但是基带控制电路和开关电路的工作负担也较小。
上面虽然将时段分成了八种情况，可以理解，上述(1)-(4)的每种情况实际包含了“全部”和“部分”两种情况，而(5)-(8)的每种情况实际上包含了“DTX全部周期+DRX部分周期”、“DTX全部周期+DRX全部周期”、“DTX部分周期+DRX部分周期”和“DTX部分周期+DRX部分周期”四种情况，上述(1)-(8)八种情况的划分，只是为了描述简单。
可选的，本发明实施例中，在上述八种时段停止对射频电路的全部或者部分电路进行供电，指的是，仅在这八种时段停止对射频电路的全部或者部分电路进行供电，以(1)为例，仅仅在无线终端的每个DTX周期中的休眠时段中的全部或部分时段，停止对射频电路的全部或者部分电路进行供电，具体的， 如果是在无线终端的每个DTX周期中的休眠时段中的全部时段停止供电，那么在无线终端的每个DTX周期中的休眠时段中的全部时段之外的其他所有时段，恢复对射频电路的全部电路的供电。如果是在无线终端的每个DTX周期中的休眠时段中的部分时段停止供电，那么在无线终端的每个DTX周期中的休眠时段中的部分时段之外的其他所有时段，恢复对射频电路的全部电路的供电。其中，恢复对射频电路的全部电路进行供电，具体可以由基带控制电路，在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向已收到了断开命令的开关电路发送连通命令，以连通之前断开的供电线路。
如果选择在(2)-(8)的时段断开射频电路的全部电路或部分电路的供电，实现方式也类似，此处不再赘述。
可选的，在(1)-(8)的时段断开射频电路的全部电路或部分电路的供电，不仅可以理解为单一的省电方案，例如每个DRX周期的全部休眠时段，对射频电路的全部电路停止供电；同时，也可以理解为多种省电方案的组合，例如：在每个DRX周期的全部休眠时段，对射频电路的全部电路断电，并且，在每个DTX周期的全部休眠时段，对射频电路中的一个电路断电。又例如：在每两个连续的DRX周期中一个DRX周期的全部休眠时段，对射频电路的两个电路断电，并且，在每三个连续的DTX周期中的一个DTX周期的全部休眠时段，对射频电路中的一个电路断电。依次类推，本领域的技术人员可以想到多种省电方案，及其组合，此处不再赘述。
具体实现时，可以根据需要设计合适的省电时段(如(1)-(8)描述的时段)和省电范围(射频电路的全部电路或部分电路)。
如果停止对射频电路的全部或者部分电路进行供电的时段是(5)--(8)的情况，当无线终端当前既有不连续发送，也有不连续接收，可能会存在一种特 殊的情况，即当前虽然处于DRX的休眠时段，但是不处于DTX的休眠时段，或者当前虽然处于DTX的休眠时段，但是不处于DRX的休眠时段，为了保证不连续发送或不连续接收的正常进行，需要维持对射频电路的相关电路的供电，为了简化设计，可以设计为：只有当前既在处于DTX的休眠时段、同时也处于DRX的休眠时段时，才停止对射频电路的全部或者部分电路进行供电。换句话说，(5)中“(1)和(3)”的含义是(1)与(3)同时满足。(6)--(8)的含义也类似。
对应的，所述基带控制电路还用于，向所述开关电路发送连通命令，控制所述开关电路在所述射频电路的全部电路或部分电路断电的时段之外的其他所有时段，连通所述射频电路的全部电路的供电线路；所述开关电路，用于接收所述连通命令，根据所述连通命令、连通对所述射频电路的全部电路的供电线路。该方案保证了在所述无线终端，在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，射频电路能够正常供电和工作。可以理解，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向开关电路发送连通命令，以实现对之前断开的供电线路的连通。
具体来说，如果是在每个DRX周期中的全部休眠时段，对射频电路的全部电路断电，那么基带控制电路持续计时，在第N个DRX周期的休眠时段开始时，基带控制电路向开关电路发送断开命令，开关电路断开射频电路中所有电路的供电，到了第N个DRX周期的休眠时段结束时(即第N个DRX周期的唤醒时段开始时)，基带控制电路向开关电路发送连通命令，开关电路连通射频电路中所有电路的供电，到了第N个DRX周期的唤醒时段结束时(即第N+1个DRX周期的休眠时段开始时)，基带控制电路向开关电路发送断开命令，开关电路 断开射频电路中所有电路的供电，依此类推。上述N为正整数，且假设在第N个DRX周期中、无线终端没有收到该无线终端需要处理的消息(例如寻呼消息)，此时，在第N个DRX周期结束后，继续第N+1个DRX周期。如果在第N个DRX周期中，无线终端收到了该无线终端需要处理的消息(例如寻呼消息)，则跳出空闲状态进入连接状态，按照现有技术中处理寻呼消息的方式，直到再次进入空闲状态、并继续按照DRX周期进行不连续接收时，再继续前述的控制供电的过程。
如图5a所示，为本发明另一个实施例提供的通信单元的结构示意图。图5a在图4的基础上，细化了射频电路的具体实现。其中电路之间连接线有两种，其中较粗的连接线表示的是供电关系，较细的连接线表示的是信号传输关系。
除了包含上述针对图4的实施例的描述，本实施例新增的内容包括：
所述射频电路包括：发射处理电路、接收处理电路和天线开关。
所述发射处理电路用于根据所述基带处理电路的命令，对上行所述基带控制电路发送的上行数字信号，转换成上行模拟信号并发送给所述天线开关。
所述接收处理电路用于接收所述天线开关发送的下行模拟信号，转换成下行数字信号发送给所述基带控制电路处理。
所述天线开关用于根据时序要求接收所述天线发送的下行模拟信号，并发送给接收处理电路，并根据时序要求接收所述发射处理电路发送的上行模拟信号，发送给所述天线。上述的各种上行数据和下行数据可参考前述实施例中的描述。
所述开关电路包括电子开关，所述电子开关设置在以下供电线路的至少一个之上：
所述电源处理电路到所述发射处理电路的供电线路、所述电源处理电路到 所述接收处理电路的供电线路、和所述电源处理电路到所述天线开关的供电线路。
所述电子开关用于根据所述断开命令、断开所述电子开关所在的供电线路。
所述基带控制电路具体用于，在所述无线终端处于休眠状态的部分时段或全部时段开始时、向所述电子开关中的至少一个发送所述断开命令。此功能是为了实现控制收到所述断开命令的电子开关、在所述无线终端处于休眠状态的部分时段或全部时段、断开收到所述断开命令的电子开关所在的供电线路。
本发明另一实施例还提供一种采用上述通信单元的无线终端，无线终端除了包含上述通信单元，还可以根据需要包含例如图3所示的其他单元，通信单元与其他单元的数据传输或连接关系，可以参考对图3的描述，此处不再重复。
如果无线终端采用本实施例提供的通信单元，可以实现在无线终端处于休眠状态时，对不需要全部的射频电路进行供电，从而减少了无线终端的电能消耗、延长了待机时间，同时也延长了无线终端中射频电路的使用寿命；同时，本实施例由于开关电路采用了一个或多个电子开关，整个方案简单、有效和灵活，同时硬件成本较低。
图5a中的开关电路包括三个电子开关，这三个电子开关分别位于所述电源处理电路到所述发射处理电路的供电线路、所述电源处理电路到所述接收处理电路的供电线路、和所述电源处理电路到所述天线开关的供电线路上，当确定无线终端进入省电功能(例如无线终端接收到用户选择的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到设定的时间段或设定的地点等)，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向这三个电子开关中的至少一个发送断开命令，收到断 开命令的电子开关立即断开该电子开关所在的供电线路，以实现切断射频电路的全部或部分供电。由于有三个电子开关分别控制三条供电线路，断电时可以更有针对性，断电的方案也更加灵活，如果有部分电子开关发生故障，剩下的无故障的电子开关仍可以实现断电，提高了方案的稳定性。
如图5b所示为为本发明另一个实施例提供的通信单元的结构示意图。与图5a不同的是，其中的开关电路包括了一个电子开关，这个电子开关同时位于所述电源处理电路到所述发射处理电路的供电线路、所述电源处理电路到所述接收处理电路的供电线路、和所述电源处理电路到所述天线开关的供电线路上，该电子开关的通断同时控制了这三条供电线路，当确定无线终端进入省电功能(例如无线终端接收到用户选择的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到设定的时间段或设定的地点等)，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向这个电子开关发送断开命令，所述电子开关收到断开命令后立即断开该电子开关所在的供电线路，以实现切断射频电路的全部供电。本方案只用到了一个电子开关，可以同时断开三条线路，断电效率更高，硬件成本更低。
可选的，上述电子开关的实现还可以有其他实现方式，例如所述电源处理电路到所述发射处理电路的供电线路、所述电源处理电路到所述接收处理电路的供电线路、和所述电源处理电路到所述天线开关的供电线路这三条线路中的两条线路公用一个电子开关，另一条线路使用一个电子开关，基带控制电路在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向这两个电子开关中的至少一个发送断开命令，收到断开命令的电子开关立即断开该电子开关所在的供电线路，以实现切断射频电路的全部或部 分供电。本方案中具有两个电子开关，即使一个电子开关出现故障，也可通过无故障的另一个电子开关完成断电，方案的稳定性更好。且由于两条线路公用一个电子开关，断电效率较高，硬件成本较低。
可选的，上述电子开关还可以总共包含四个电子开关，其中一个开关作为所述电源处理电路到所述发射处理电路的供电线路、所述电源处理电路到所述接收处理电路的供电线路、和所述电源处理电路到所述天线开关的供电线路这三条线路的总开关，另外三个电子开关为分开关，分别位于这三条线路上，基带控制电路在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向总开关发送断开命令以断开射频电路的全部供电；或者向三个分开关同时发送断开命令以断开射频电路的全部供电；或者向三个分开关中的一个或两个发送断开命令，以断开射频电路的部分供电。本方案既设置有总开关，同时还设置有分开关，可根据需要灵活的选择断电方案，即使部分电子开关出现故障，也可通过无故障的电子开关完成断电，方案的稳定性更好。
需要说明的是，需要说明的是，图5c和图5d的实施例描述中，射频电路的组成划分主要是依据功能，实际产品中，可以有多个芯片实现一个电路的功能，也可以有几个电路在一个芯片中实现，例如接收处理电路、发射处理电路和天线开关可以合并到一个芯片中。
如图5c所示，为本发明另一个实施例提供的通信单元的结构示意图。图5c在图4的基础上，细化了射频电路的具体实现。其中电路之间连接线有两种，其中较粗的连接线表示的是供电关系，较细的连接线表示的是信号传输关系。
除了包含上述针对图4的实施例的描述，本实施例新增的内容包括：
所述射频电路包括:发射处理电路和接收处理电路。
所述发射处理电路用于根据所述基带处理电路的命令，对上行所述基带控制电路发送的上行数字信号，转换成上行模拟信号并发送给所述天线。
所述接收处理电路用于接收所述天线发送的下行模拟信号，转换成下行数字信号发送给所述基带控制电路处理。
所述开关电路包括电子开关，所述电子开关设置在以下供电线路的至少一个之上：
所述电源处理电路到所述发射处理电路的供电线路，和所述电源处理电路到所述接收处理电路的供电线路。
所述电子开关用于根据所述断开命令、断开所述电子开关所在的供电线路；
所述基带控制电路具体用于，在所述无线终端处于休眠状态的部分时段或全部时段开始时、向所述电子开关中的至少一个发送所述断开。该功能是为了实现控制收到所述断开命令的电子开关、在所述无线终端处于休眠状态的部分时段或全部时段、断开收到所述断开命令的电子开关所在的供电线路。
本发明另一实施例还提供一种采用上述通信单元的无线终端，无线终端除了包含上述通信单元，还可以根据需要包含例如图3所示的其他单元，通信单元与其他单元的数据传输或连接关系，可以参考对图3的描述，此处不再重复。
如果无线终端采用本实施例提供的通信单元，可以实现在无线终端处于休眠状态时，对不需要全部的射频电路进行供电，从而减少了无线终端的电能消耗、延长了待机时间，同时也延长了无线终端中射频电路的使用寿命；同时，本实施例由于开关电路采用了一个或多个电子开关，整个方案简单、有效和灵活，同时硬件成本较低。
图5c中的开关电路包括两个电子开关，这两个电子开关分别位于所述电源处理电路到所述发射处理电路的供电线路、和所述电源处理电路到所述接收处 理电路的供电线路上，当确定无线终端进入省电功能(例如无线终端接收到用户选择的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到设定的时间段或设定的地点等)，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向这两个电子开关中的至少一个发送断开命令，收到断开命令的电子开关立即断开该电子开关所在的供电线路，以实现切断射频电路的全部或部分供电。由于有两个电子开关分别控制两条供电线路，断电时可以更有针对性，断电的方案也更加灵活，如果有一个电子开关发生故障，剩下的无故障的电子开关仍可以实现断电，提高了方案的稳定性。
如图5d所示为为本发明另一个实施例提供的通信单元的结构示意图。与图5c不同的是，其中的开关电路包括了一个电子开关，这个电子开关同时位于所述电源处理电路到所述发射处理电路的供电线路、和所述电源处理电路到所述接收处理电路的供电线路上，该电子开关的通断同时控制了这三条供电线路，当确定无线终端进入省电功能(例如无线终端接收到用户选择的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到设定的时间段或设定的地点等)，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向这个电子开关发送断开命令，所述电子开关收到断开命令后立即断开该电子开关所在的供电线路，以实现切断射频电路的全部供电。本方案只用到了一个电子开关，可以同时断开三条线路，断电效率更高，硬件成本更低。
可选的，上述电子开关还可以总共包含三个电子开关，其中一个开关作为 所述电源处理电路到所述发射处理电路的供电线路、和所述电源处理电路到所述接收处理电路的供电线路这两条线路的总开关，另外两个电子开关为分开关，分别位于这两条线路上，基带控制电路在给射频电路停止供电的时段(无线终端处于休眠状态的部分时段或全部时段)开始时，就向总开关发送断开命令以断开射频电路的全部供电；或者向两个分开关同时发送断开命令以断开射频电路的全部供电；或者向两个分开关中的一个发送断开命令，以断开射频电路的部分供电。本方案既设置有总开关，同时还设置有分开关，可根据需要灵活的选择断电方案，即使部分电子开关出现故障，也可通过无故障的电子开关完成断电，方案的稳定性更好。
可选的，在前述的所有无线终端的实施例的基础上，所述基带控制电路还用于，在所述射频电路的全部电路或部分电路断电的时段结束时、向设置在供电线路上的至少一个电子开关发送连通命令，控制所述至少一个电子开关、在所述无线终端处于唤醒状态时、连通所述至少一个电子开关所在的供电线路。
需要说明的是，图5c和图5d的实施例描述中，射频电路的划分主要是按照功能划分，实际产品中，可以有多个芯片实现一个电路的功能，也可以有几个电路在一个芯片中实现，例如接收处理电路和发射处理电路可以合并到一个芯片中。
可选的，在上述针对图5a-图5d的实施例中，所述基带控制电路还用于，在所述射频电路的全部电路或部分电路断电的时段结束时、向收到了所述断开命令的所有的电子开关，发送连通命令。该功能是为了控制收到连通命令的电子开关、所述射频电路的全部电路或部分电路断电的时段之外的其他所有时段、连通所述控制收到连通命令的电子开关所在的供电线路。所述电子开关，还用于接收所述连通命令，根据所述连通命令、连通所述电子开关所在的供电线路。 该方案保证了无线终端、在停止对所述无线终端中的射频电路的部分电路的供电的时段之外的其他时段，射频电路正常供电和工作。可以理解，基带控制电路的供电可以一直维持，保持基带控制电路持续的计时，并在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向已收到过断开命令的电子开关发送连通命令，以实现对之前断开的供电线路的连通。
可选的，如果无线终端在整个控制供电的过程中，收到了用户发送的退出省电模式的命令，或者是无线终端关机了，或者是无线终端的剩余电量高于某一设定阈值，或者是进入了特定的时段，或者是无线终端处于特定的位置，或者是无线终端从空闲状态切换到连接状态，或者是其他设定的条件，该方法立即中止。等到再次收到用户输入的进入省电模式的命令或者其他触发条件时，才开始执行该控制供电的过程。具体的，可以由无线终端中的处理器单元监控，如果监控到前述的中止条件发生，则通知通信单元中的基带控制电路停止正在执行前述的控制供电的过程，如果已发送了断开命令尚未发送连通命令，则立即向接收了断开命令的开关电路发送连通命令，在控制供电的流程重启之前，不再发送断开命令；如果发送了断开命令之后已发送了连通命令，则在控制供电的流程重启之前，不再发送断开命令。
本发明实施例还提供一种控制供电的方法，该方法适用于会进入休眠状态的无线终端。该方法包括：
在无线终端处于休眠状态的部分时段或全部时段，停止对所述无线终端中的射频电路的部分或全部电路的供电；
其中，所述休眠状态包括以下至少一个：不连续发送DTX周期中的休眠状态，和不连续接收DRX周期中的休眠状态。采用DRX或者DTX周期中至少一 个休眠状态部分时段或全部时段，对射频电路的部分或全部电路的供电，其断电的时段更加灵活多样。
本发明的执行主体可以是无线终端，也可以是无线终端的基带控制电路。
可以理解，停止对所述射频电路的部分或全部电路的供电的时间，不大于所述无线终端处于休眠状态的时间
参考之前的描述，当无线终端处于DTX周期中的休眠状态时，不接收网络侧设备发送的消息，无线终端的部分电路此时处于低功耗的状态。当无线终端处于DTX周期中的休眠状态时，不向网络侧设备发送消息，无线终端的部分电路此时处于低功耗的状态。
触发本方法执行的，可以是无线终端接收到用户选择的命令，或者无线终端自动检测到剩余电量低于某个阈值，或者是无线终端检测到当前处于设定的时间段或检测到无线终端位于设定的地点等。
本实施例中所述的射频电路的含义，可以参考前述的装置实施例中对射频电路的描述。
根据本实施例的描述，停止对射频电路的全部或者部分电路进行供电的时段具体包括以下8种时段：
(a)在无线终端的DTX周期中的休眠时段的全部时段；
(b)在无线终端的DTX周期中的休眠时段的部分时段；
(c)在无线终端的DRX周期中的休眠时段的全部时段；
(d)在无线终端的DRX周期中的休眠时段的部分时段；
(e)(a)和(c)所述的时段；
(f)(a)和(d)所述的时段；
(g)(b)和(c)所述的时段；
(h)(b)和(c)所述的时段；
其中，DTX周期中休眠时段的全部时段是指，DTX周期中的所有休眠时段，DTX周期的数目为至少一个。DTX周期中的休眠时段的部分时段是指，DTX周期中休眠时段的一部分，DTX周期的数目为至少一个，例如：一个DTX周期中休眠时段的前二分之一，或者所有DTX周期中休眠时段的前三分之一等。
其中，DRX周期中休眠时段的全部时段是指，DRX周期中的所有休眠时段，DRX周期的数目为至少一个。DRX周期中的休眠时段的部分时段是指，DRX周期中休眠时段的一部分，DRX周期的数目为至少一个，例如：一个DRX周期中休眠时段的前二分之一，或者所有DTX周期中休眠时段的前三分之一等。
采用本发明实施例的方法，可以实现在无线终端处于休眠状态时，对不需要全部的射频电路进行供电，从而减少了无线终端的电能消耗、延长了待机时间，同时，由于射频电路在长期供电的情况下，可靠性会逐渐降低，因此本发明实施例也延长了无线终端中射频电路的使用寿命。
可选的，本发明实施例中，在上述八种时段停止对射频电路的全部或者部分电路进行供电，指的是，仅在这八种时段停止对射频电路的全部或者部分电路进行供电，以(a)为例，仅仅在无线终端的DTX周期中的休眠时段的全部时段，停止对射频电路的全部或者部分电路进行供电，当所述基带控制电路在DTX周期的休眠时段的全部时段之外的其他所有时段，恢复对射频电路的全部电路进行供电。其他的(b)-(h)的情况类似，此处不再赘述。无线终端恢复对射频电路的全部电路进行供电，具体可以由基带控制电路、在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向已收到了断开命令的开关电路发送连通命令，以连通之前断开的供电线路。
如果停止对射频电路的全部或者部分电路进行供电的时段是(e)--(h)的 情况，当无线终端当前既有不连续发送，也有不连续接收，可能会存在一种特殊的情况，即当前虽然处于DRX的休眠时段，但是不处于DTX的休眠时段，或者当前虽然处于DTX的休眠时段，但是不处于DRX的休眠时段，为了保证不连续发送或不连续接收的正常进行，需要维持对射频电路的相关电路的供电，为了简化设计，可以设计为：只有当前既在处于DTX的休眠时段、同时也处于DRX的休眠时段时，才停止对射频电路的全部或者部分电路进行供电。换句话说，(e)中“(a)和(c)”的含义是(a)与(c)同时满足。(f)--(h)的含义也类似。
可选的，所述不连续发送DTX周期中的休眠状态，具体为：全部DTX周期中的休眠状态，或者部分DTX周期中的休眠状态；
所述不连续接收DRX周期中的休眠状态，具体为：全部DRX周期中的休眠状态，或者部分DRX周期中的休眠状态。
这意味着，在前述的(a)-(h)的停止供电时段的基础上进一步细化，可以在以下8种时段中停止对所述射频电路的部分或全部电路的供电：
(1)在无线终端的每个DTX周期中的休眠时段中的全部或部分时段；
(2)在无线终端的部分DTX周期中的休眠时段中的全部或部分时段；
(3)在无线终端的每个DRX周期中的休眠时段中的全部或部分时段；
(4)在无线终端的部分DRX周期中的休眠时段中的全部或部分时段；
(5)在(1)和(3)所述的时段；
(6)在(2)和(4)所述的时段；
(7)在(1)和(4)所述的时段；
(8)在(2)和(3)所述的时段。
其中，(2)中所述的部分DTX周期和(4)中所述的部分DTX周期的选 择方式有多种，例如可以每两个连续的周期中选择一个，或每三个连续的周期中选择一个或两个，或者每四个连续的周期中选择前两个等。选择时可以基于算法复杂程度和省电效率等选择合适的“部分周期”，其选择方式不构成对本发明的限定。可以理解，断电的总时间越长，省电的效果越明显，但是省电的总时间较少时，虽然省电效果较弱，但是无线终端中负责供电控制的模块的负担也较小。
在本发明实施例提供的另一个方法实施例中，上面虽然将时段分成了八种情况，可以理解，上述(1)-(4)的每种情况实际包含了“全部”和“部分”两种情况，而(5)-(8)的每种情况实际上包含了“全部+部分”、“全部+全部”、“部分+部分”和“部分+全部”四种情况，上述八种情况的划分，只是为了描述简单。
可选的，本发明实施例中，在上述八种时段停止对射频电路的全部或者部分电路进行供电，指的是，仅在这八种时段停止对射频电路的全部或者部分电路进行供电，以(1)为例，仅仅在无线终端的每个DTX周期中的休眠时段中的全部或部分时段，停止对射频电路的全部或者部分电路进行供电，具体的，如果是在无线终端的每个DTX周期中的休眠时段中的全部时段停止供电，那么在无线终端的每个DTX周期中的休眠时段中的全部时段之外的其他所有时段，恢复对射频电路的全部电路的供电。如果是在无线终端的每个DTX周期中的休眠时段中的部分时段停止供电，那么在无线终端的每个DTX周期中的休眠时段中的部分时段之外的其他所有时段，恢复对射频电路的全部电路的供电。
可选的，在(1)-(8)的时段断开射频电路的全部电路或部分电路的供电，不仅可以理解为单一的省电方案，例如每个DRX周期的全部休眠时段，对射频电路的全部电路停止供电；同时，也可以理解为多种省电方案的组合，例如在 每个DRX周期的全部休眠时段，对射频电路的全部电路断电，并且，在每个DTX周期的全部休眠时段，对射频电路中的部分电路断电。具体实现时，可以根据需要设计合适的省电时段(如(1)-(8)描述的时段)和省电范围(射频电路的全部电路或部分电路)。
如果停止对射频电路的全部或者部分电路进行供电的时段是(5)--(8)的情况，当无线终端当前既有不连续发送，也有不连续接收，可能会存在一种特殊的情况，即当前虽然处于DRX的休眠时段，但是不处于DTX的休眠时段，或者当前虽然处于DTX的休眠时段，但是不处于DRX的休眠时段，为了保证不连续发送或不连续接收的正常进行，需要维持对射频电路的相关电路的供电，为了简化设计，可以设计为：只有当前既在处于DTX的休眠时段、同时也处于DRX的休眠时段时，才停止对射频电路的全部或者部分电路进行供电。换句话说，(5)中“(1)和(3)”的含义是(1)与(3)同时满足。(6)--(8)的含义也类似。
具体来说，如果是在每个DRX周期中的全部休眠时段，对射频电路的全部电路断电，那么无线终端(具体可以为基带控制电路)持续计时，在第N个DRX周期的休眠时段开始时，无线终端断开射频电路中所有电路的供电(具体可以是：基带控制电路向开关电路发送断开命令，开关电路断开射频电路中所有电路的供电)，到了第N个DRX周期的休眠时段结束时(即第N个DRX周期的唤醒时段开始时)，无线终端恢复对射频电路中所有电路的供电(具体可以是：基带控制电路向开关电路发送连通命令，开关电路连通射频电路中所有电路的供电)，到了第N个DRX周期的唤醒时段结束时(即第N+1个DRX周期的休眠时段开始时)，无线终端再次断开射频电路中所有电路的供电(具体可以是：基带控制电路向开关电路发送断开命令，开关电路断开射频电路中所有电路的 供电)，依此类推。上述N为正整数，且假设在第N个DRX周期中、无线终端没有收到该无线终端需要处理的消息(例如寻呼消息)，此时，在第N个DRX周期结束后，继续第N+1个DRX周期。如果在第N个DRX周期中，无线终端收到了该无线终端需要处理的消息(例如寻呼消息)，则跳出空闲状态进入连接状态，按照现有技术中处理寻呼消息的方式，直到再次进入空闲状态、并继续按照DRX周期进行不连续接收时，再继续前述的控制供电的过程。
在本发明实施例提供的另一个方法实施例中，无线终端的射频电路包括：发射处理电路、接收处理电路和天线开关；其中这三个部件的描述，可以参考之前的图5a-图5b的相关实施例的描述。

断开位于所述发射处理电路的供电线路上的电子开关、断开位于所述发射处理电路的供电线路上的电子开关和断开位于所述天线开关的供电线路上的电子开关。
可以理解，电子开关的数目至少有一个，电子开关的位置可以参考之前关于图5a—图5b的具体实施例，此处不再重复。需要说明的是，本实施例提供了一种灵活控制射频电路的供电的方案，根据需要，选择在前述的无线终端处于休眠状态的部分时段或全部时段，断开射频电路中特定部分的供电。
其中，恢复对射频电路的全部电路进行供电，具体可以由基带控制电路、 在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向已收到了断开命令的电子开关发送连通命令，以连通之前断开的供电线路，从而保证无线终端在断电结束后，恢复正常供电和工作。
在本发明实施例提供的另一个方法实施例中，所述射频电路包括：发射处理电路和接收处理电路；其中这三个部件的描述，可以参考之前的图5c-图5d的相关实施例的描述。
停止对所述无线终端中的射频电路的部分电路的供电，具体包括：

停止对所述无线终端中的射频电路的全部电路的供电，具体包括：

断开位于所述接收处理电路的供电线路上的电子开关。
可以理解，电子开关的数目至少有一个，电子开关的位置可以参考之前关于图5c—图5d的具体实施例，此处不再重复。需要说明的是，本实施例提供了一种灵活控制射频电路的供电的方案，根据需要，选择在前述的无线终端处于休眠状态的部分时段或全部时段，断开射频电路中特定部分的供电。
其中，恢复对射频电路的全部电路进行供电，具体可以由基带控制电路、在停止对所述无线终端中的射频电路的部分电路的供电的时段结束时，向已收到了断开命令的电子开关发送连通命令，以连通之前断开的供电线路，从而保证无线终端在断电结束后，恢复正常供电和工作。
可选的，如果无线终端在整个方法的执行过程中，收到了用户发送的退出省电模式的命令，或者是无线终端关机了，或者是无线终端的剩余电量高于某一阈值，或者是进入了特定的时段，或者是无线终端处于特定的位置，或者是 无线终端从空闲状态切换到连接状态，或者是其他设定的条件，该方法立即中止，等到再次收到用户输入的进入省电模式的命令或者其他触发条件时，才开始执行该控制供电的方法。
如图6所示，为本发明实施例提供的控制供电的方法流程图，该方法的执行主体为无线终端。该无线终端的射频电路的各个电路的供电电路可以通过开关电路断开和连通。该方法包括如下步骤：
601、接收用户输入的进入省电模式的命令。
当用户输入进入省电模式的命令，触发控制供电的方法执行。此处的省电模式可以与无线终端现有的省电模式融合，例如，在现有省电模式的基础上增加一个子选项，当选择了该子选项时触发控制供电的方法；或者直接在现有省电模式被选择时，触发控制供电的方法。进入省电模式的命令可以通过无线终端的输入单元输入，具体可参考图3中关于输入单元的描述，此处不再赘述。如之前的实施例所述，此处的601也可以替换为无线终端检测到无线终端当前处于设定的位置，或者当前处于设定的时间段等，或者无线终端开机后自动执行等，或无线终端自动检测到剩余电量低于某个阈值等，此处不再重复。
602、读取省电数据。
此处的省电数据，包括断开射频电路的哪些电路，以及停止对所述无线终端中的射频电路的部分电路的供电的时段等。后续将按照省电数据来控制无线终端的射频电路的供电。本实施例中，断电的范围是射频电路的全部电路，可选的，也可以只是射频电路的部分电路，具体可以参考之前的实施例描述。
603、判断是否进入断电时段，如果是，继续执行604，如果否，继续执行603。
此处，可以由基带控制电路进行计时，如果进入了断电时段(停止对所述无线终端中的射频电路的部分电路的供电的时段，例如：所有DRX周期中的休眠时段)，则触发后续604，如果没有到断电时段，则继续计时。
604、断开射频电路的全部电路的供电。
此处可以由基带控制电路向开关电路发送断开命令，以切断射频电路的所有电路的供电。
605、判断断电时段是否结束，如果是，继续执行606，如果否，继续执行605。
此处可以由基带控制电路持续计时，如果断电时段已经结束，则继续606，如果断电时段还没结束，则由基带控制电路继续计时。
606、恢复射频电路的全部供电，继续执行603。
此处，可以由基带控制电路向开关电路发送连通命令，以恢复射频电路的所有电路的供电。
可选的，在恢复了供电之后，基带控制电路可以持续计时，判断是否再次进入省电时段，此处情况适用于断电时段不仅仅只有一个持续的时间段，而是多个非连续的时间段，如果在整个过程中，无线终端从空闲状态切换到连接状态，则无线终端按照现有技术中的连接状态处理相关消息，等到无线终端再次进入空闲状态时，或者其他触发条件满足时，再继续执行该控制供电的方法。
具体可以参考之前实施例的描述，例如断电时段为每个DRX周期中的全部休眠时段，此时需要在每个DRX周期中的都执行一次断电。
可选的，如果无线终端在整个方法的执行过程中，收到了用户发送的退出省电模式的命令，或者是无线终端关机了，或者是无线终端的剩余电量高于某一阈值，或者是进入了特定的时段，或者是无线终端处于特定的位置，或者是 无线终端从空闲状态切换到连接状态，或者是其他设定的条件，该方法立即中止，等到再次收到用户输入的进入省电模式的命令时再执行601之后的步骤、或者无线终端重启后自动执行601之后的步骤。
本实施例提供的方法，给出了一种控制供电的具体方案，由于可以根据断电时段，断开全部射频电路的供电，能够明显减少电能的消耗，延长了待机时间和射频电路的使用寿命。
需要说明的是，可以选用现有技术中电子开关来作为本发明各种实施例中提到的电子开关，特别的，需要选择响应时间较短的的电子开关，以提高供电控制的精度，另外，为了能够保证在电子开关的连通瞬间，给后级的器件供电不会超过其额定输入电压，可以考虑在电子开关中的电源输出之前设置一个吸收瞬间大电压的电容。如图7所示，为本发明实施例中采用的一种电子开关的结构示意图，该电子开关包括：缓启动电路，开关主体电路和滤波电路，这三个电路依次电连通。其中的较粗的箭头表示电能传递关系，较细的箭头表示的是信号传输关系。所述缓启动电路与电源处理电路电连通，所述滤波电路与射频电路电连通，基地控制电路发出的连通命令或者断开命令发送给开关主体电路执行。其中缓启动电路用于实现电流缓慢启动，开关主体电路用于根据连通命令实现电连通，根据断开命令实现电断开，滤波电路用于滤除开关主体电路在断开和闭合瞬间产生的噪声。上述三个电路可以采用现有技术中的各种实现方式，此处不作限定。
以上是对本发明具体实施例的说明，在具体的实施过程中可对本发明的方法进行适当的改进，以适应具体情况的具体需要。因此可以理解，根据本发明的具体实施方式只是起示范作用，并不用以限制本发明的保护范围。
