参照图3，图3为本发明双通道移动终端一实施例的功能模块示意图。本实施例中，双通道移动终端具体包括主调制解调器310(MDM1)与主射频集成电路320(RFIC1)、从调制解调器410(MDM2)与从射频集成电路420(RFIC2)，其中，主调制解调器310与主射频集成电路320构成双通道移动终端进行业务处理的第一通道，而从调制解调器410与从射频集成电路420则构成了双通道移动终端进行业务处理的第二通道。
其中，主调制解调器310中包括用于与用户进行应用交互的应用处理器AP，主调制解调器310与从调制解调器410具体用于：将各种数字基带 信号转换成适于信道传输的数字调制信号(已调信号或频带信号)；以及在接收端将收到的数字频带信号还原成数字基带信号。而主射频集成电路320与从射频集成电路420具体用于完成本设备的调制信号的发送与其它设备的调制信号的接收。
本实施例中，鉴于现有双通道移动终端在同时进行数据业务时，由于处于同一个基站小区，也即通道1、2采用相同信道工作时，比如在时分双工TDD制式下同时进行数据业务时，若通道1进行数据接收，而通道2进行数据上传，则通道1、2之间会存在相互干扰，进而影响数据业务的正常进行。因此，本实施例中，通过在双通道移动终端中采用双通道数据同步装置510，以控制第一通道数据业务数据与第二通道数据业务数据保持同步。
如图4所示，双通道数据同步装置510具体包括晶体振荡器610、电源管理芯片620。本实施例中，晶体振荡器610能够根据自身特性(上电后产生振动)而产生稳定的振动频率，同时，采用晶体振荡器610的振动频率并配合电源管理芯片620即可产生时钟信号，其中，电源管理芯片620为一种电源管理集成电路，包括向处理器、调制解调器、射频集成电路等移动终端部件提供所需的具有时钟信号特征的特定大小电压的电源，本实施例中，对于时钟信号的具体产生过程与现有技术相似，因此不做过多赘述。
本实施例中，双通道移动终端通过晶体振荡器610与电源管理芯片620(PMIC)分别向第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420供应相同的时钟信号，以使第一通道数据业务数据与第二通道数据业务数据在处理时间上保持同步。同时，本实施例中采用一个晶体振荡器与一个电源管理芯片能够提高双通道移动终端内部部件的集成度，提升生产效率。
可选的，如图5所示的双通道移动终端一实施例的连接示意图。晶体 振荡器610与电源管理芯片620连接；电源管理芯片620分别与第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420连接。如图5所示，由同一个晶体振荡器610与同一个电源管理芯片620所产生的两路时钟信号(在电源管理芯片内部可将一路时钟信号分成两路)能够保证信号相位与频率的同步，从而使第一通道数据业务数据与第二通道数据业务数据在处理时间上保持同步。也即使第一通道的基带时钟信号BBCLK1、射频时钟信号RFIC1与第二通道的基带时钟信号BBCLK2、射频时钟信号RFIC2保持同步。
本实施例中，为避免双通道数据工作时所产生的信号干扰，通过晶体振荡器610与电源管理芯片620所产生的同步时间信号，并向第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420供应相同的时钟信号，以使第一通道数据业务数据与第二通道数据业务数据在处理时间上保持同步，进而在移动终端上实现双通道数据业务工作时的同步，以避免双通道数据工作时所产生的信号干扰。此外，通过本发明还能避免移动终端生产过程中的各种综合测试中所出现的测试干扰。
参照图6，图6为本发明双通道移动终端中电源管理芯片一实施例的功能模块示意图。基于所述实施例，本实施例中，所述电源管理芯片620包括第一电源管理芯片6201(PMIC1)、第二电源管理芯片6202(PMIC2)以及同步电路6203。
本实施例中，晶体振荡器610与第一电源管理芯片6201可产生一路时钟信号(比如为第一路时钟信号)，而晶体振荡器610与第二电源管理芯片6202也可产生一路时钟信号(比如为第二路时钟信号)，由于第一路时钟信号与第二路时钟信号都由同一个晶体振荡器610提供振荡频率，因此，理论上第一路时钟信号与第二路时钟信号可以相同，但第一路时钟信号与第 二路时钟信号的产生过程中有可能存在延时而导致最终输出的时钟信号不同步，因此，鉴于以上问题，本实施例中采用同步电路6203以同步第一路时钟信号与第二路时钟信号。
本实施例中，对于同步电路6203的设置及实现方式不限，例如，同步电路6203可使用专用的闭环跟踪(PLL，Phase Locked Loop)电路，通过比较并调节经第一电源管理芯片6201、第二电源管理芯片6202后产生的两路时钟信号的相位和频率，进而使得两路时钟信号保持同步。
本实施例中，双通道数据同步装置510通过晶体振荡器610、第一电源管理芯片6201、第二电源管理芯片6202以及同步电路6203，分别对应向第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420供应相同的时钟信号，以使第一通道数据业务数据与第二通道数据业务数据在处理时间上保持同步，进而避免两路通道同时进行数据业务处理时所存在的相互干扰问题。
可选的，如图7所示的双通道移动终端另一实施例的连接示意图。晶体振荡器610分别与第一电源管理芯片6201、第二电源管理芯片6202连接；第一电源管理芯片6201通过同步电路6203与第二电源管理芯片6202连接；第一电源管理芯片6201分别与第一通道的主调制解调器310与主射频集成电路320连接；第二电源管理芯片6202分别与第二通道的从调制解调器410与从射频集成电路420连接。如图7所示，由同一个晶体振荡器610与第一电源管理芯片6201、第二电源管理芯片6202所产生的两路时钟信号，并通过同步电路6203的调整后能够保证两路时钟信号相位与频率的同步，从而使第一通道数据业务数据与第二通道数据业务数据在处理时间上保持同步。也即使第一通道的基带时钟信号BBCLK1、射频时钟信号RFIC1与第二通道的基带时钟信号BBCLK2、射频时钟信号RFIC2保持同步。
可选的，在本发明双通道移动终端一实施例中，双通道移动终端通过 第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420可以同时处理相同的或不同的4G数据业务。
本实施例中，应用处理器(AP)可接收用户触发的操作指令，并获取操作指令对应的类型，然后根据操作指令对应的类型，将所述操作指令对应下发至主调制解调器310，此时，当所述操作指令为网络操作指令(也即进行数据业务)时，可同时将所述网络操作指令发送至主调制解调器310与从调制解调器410，双通道移动终端可以通过两个调制解调器提供的双通道提高通信效率，特别是两个调制解调器可以在所述操作指令的类型为网络操作指令时，主调制解调器310与从调制解调器410均通过4G网络完成数据的传输。相对于现有技术而言，当主调制解调器310通过4G网络进行数据业务时，从调制解调器410仍然可以通过4G网络进行数据业务，而无需降至3G或2G网络，这样，可以显著提高移动终端进行通信时的数据传输效率。
例如以网络业务如上网为例，数据传输由主调制解调器310和从调制解调器410同时处理。
通过主调制解调器310所对应的第一SIM卡的LTE进行上网时，数据通道的数据流向为：
上行数据：用户数据→应用处理器→主调制解调器→主射频集成电路→运营商网络→internet网络；
下行数据：internet网络→运营商网络→主射频集成电路→主调制解调器→应用处理器→用户数据；
同时，通过从调制解调器410所对应的第二SIM卡的LTE进行上网时，数据通道的数据流向为：
上行数据：用户数据→应用处理器→从调制解调器→从射频集成电路 →运营商网络→internet网络；
下行数据：internet网络→运营商网络→从射频集成电路→从调制解调器→应用处理器→用户数据。
可选的，在本发明双通道移动终端一实施例中，双通道移动终端通过第一通道的主调制解调器310与主射频集成电路320、第二通道的从调制解调器410与从射频集成电路420可以同时处理4G数据业务与语音业务。
在本可选实施例中，当应用处理器所接收到的操作指令为网络与通信操作指令时，应用处理器将网络操作指令发送至主调制解调器310中，将通信操作指令发送至从调制解调器410，进而通过主调制解调器310、主射频集成电路320进行电话、短信、彩信等语音类业务，同时通过从调制解调器410、从射频集成电路420进行4G等网络上网。进一步地，在其他实施例中，还可通过主调制解调器310、主射频集成电路320进行4G等数据业务，同时通过从调制解调器410、从射频集成电路420进行电话、短信、彩信等语音类业务。本实施例中双通道移动终端不仅可以进行打电话、发短信等语音业务，同时还可以进行上网等4G数据业务，如此，可进一步提高双通道移动终端进行业务处理时的数据传输效率和功能多样性。
例如，具体以语音业务如打电话为例，语音数据传输由主调制解调器310处理，上网数据传输由从调制解调器410处理，数据通道的数据流向为：
(主叫用户)双通道移动终端的话筒→CODEC→ADSP→主调制解调器→主射频集成电路→运营商网络→主射频集成电路→主调制解调器→ADSP→CODEC→被叫用户移动终端的喇叭；
同时，双通道移动终端可以通过从调制解调器实现数据网络业务：
上行数据：用户数据→应用处理器→从调制解调器→从射频集成电路→运营商网络→internet网络；
下行数据：internet网络→运营商网络→从射频集成电路→从调制解调 器→应用处理器→用户数据。
