为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现 有技术描述中所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，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，所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
目前，很多无线终端可以至少包括两种制式，而对于不同的网络运营商，无线终端包括的至少两种制式也不相同，例如，当网络运营商为联通时，无线终端可以包括LTE和GSM两种制式，当网络运营商为移动时，无线终端可以包括LTE和CDMA两种制式。参见图1为本发明实施例提供一种无线终端的结构示意图，该无线终端包括：主集天线11、第一天线12、第二天线13、第一射频电路14、频率隔离模块15和第二射频电路16，其中：
主集天线11连接第一射频电路14，用于收发第一制式信号，第一制式信号的频段包括超高频的第一频段和高频的第二频段。以第一制式信号是LTE信号为例进行说明，此时，主集天线为LTE主集天线，超高频的第一频段范围为2300HMZ以上，高频的第二频段范围为1710HMZ至2170HMZ，第一射频电路为LTE收发射频电路。
第一天线12连接频率隔离模块15的天线端，频率隔离模块15的高频端与第一射频电路14相连接，频率隔离模块的低频端与第二射频电路16相连接，第一天线12用于接收第一频段的第一制式信号以及收发第二制式信号，第二制式信号的频段与第一频段不重合。以第二制式信号是GSM信号为例进行说明，此时，GSM频段范围为1990HMZ以下，由于LTE信号的第一频段范围为2300HMZ以上，因此，LTE信号的第一频段与GSM频段是不重合的，使用频率隔离模块可以实现LTE信号的第一频段与GSM频段隔离，第二射频电路为GSM收发射频电路，频率隔离模块可以是双工器等等，其中双工器的原理为两个滤波器。
第二天线13连接第一射频电路14，用于接收第二频段的第一制式信号。
本实施例中的无线终端设置三根天线，主集天线和第一天线为全频段天线，由于第二天线接收的是高频段的第二频段的第一制式信号，高频段的第二频段相对于相关技术中的GSM频段要高，因此，第二天线的尺寸相对于相关技术中的GSM天线的 尺寸减小很多，相应地无线终端的尺寸也减小很多，可见，该方案中的第二天线有助于减少无线终端的整体尺寸。
参见图2为本发明实施例提供的另一种无线终端的结构示意图，在如图1所示的无线终端的基础上，还包括切换模块17。
切换模块17与第一天线12、第二天线13、频率隔离模块15的天线端和第一射频电路14连接，用于切换第一天线12接收第二频段的第一制式信号。
由于第一天线为全频段天线，性能比第二天线优越，而对于GSM制式来说，有90％的时间GSM收发射频电路都处于待机状态，也就是说第一天线有很多时间都处于空闲状态，为了充分利用性能更加优越的第一天线，因此，可以根据需要使用切换模块来实现切换第一天线接收第二频段的第一制式信号。
切换模块17的实现方式有多种，下面列举两种实现方式进行说明。
第一种实现方式，参见图3所示的无线终端的结构示意图，切换模块17包括第一单刀双掷开关171和第二单刀双掷开关172，其中：
第一单刀双掷开关171的不动端与第一天线12连接，第一单刀双掷171开关的动端在频率隔离模块15的天线端和第二单刀双掷开关172之间进行切换，通过切换第一单刀双掷开关的动端，可以实现切换第一天线与频率隔离模块连接，或者切换第一天线与第二单刀双掷开关连接。
第二单刀双掷172开关的不动端与第一射频电路14连接，第二单刀双掷开关172的动端在第一单刀双掷开关171和第二天线13之间进行切换，通过切换第二单刀双掷开关的动端，可以实现切换第一射频电路与第二天线连接，或者切换第一射频电路与第一单刀双掷开关连接。
第二种实现方式，参见图4所示的无线终端的结构示意图，切换模块17包括双刀双掷开关173，其中，双刀双掷开关与第一天线、第二天线、频率隔离模块和第一射频电路的连接方式可以有以下两个方式：
第一，双刀双掷开关173的两个不动端分别与第一天线12和第二天线13连接，双刀双掷开关173的两个动端分别与频率隔离模块15的天线端以及第一射频电路14连接，通过切换双刀双掷开关的动端，可以实现切换第一天线与频率隔离模块连接，第二天线与第一射频电路连接；或者，实现切换第一天线与第一射频电路连接。
第二，双刀双掷开关173的两个动端分别与第一天线12和第二天线13连接，双刀双掷开关173的两个不动端分别与频率隔离模块15的天线端以及第一射频电路14连接，通过切换双刀双掷开关的动端，可以实现切换第一天线与频率隔离模块连接， 第二天线与第二射频电路连接；或者，实现切换第一天线与第一射频电路连接。
通过两个单刀双掷开关或者一个双刀双掷开关可以实现切换第一天线接收第二频段的第一制式信号，从而确保充分利用性能更加优越的第一天线，同时确保第二频段的第一制式信号性能更优。
参见图5为本发明实施例提供的再一种无线终端的结构示意图，该无线终端在如图2所示的无线终端的结构的基础上还包括基带芯片18，其中，基带芯片18与第一射频电路14、第二射频电路16和切换模块17连接，用于通过控制切换模块17实现控制第二天线或者第一天线接收第二频段的第一制式信号，并且控制第一射频电路收发第一制式信号以及控制第二射频电路收发第二制式信号。
以下均以第一制式信号为LTE信号、第二制式信号为GSM信号为例进行说明，其中，第一频段的第一制式信号表示为LTE_UHB，第二频段的第一制式信号表示为LTE_HB。
参见图6为本发明实施例提供的一种无线终端的天线切换控制方法的流程图，该方法可以应用在如图5所示的无线终端中，该方法的执行主体可以但不限于是如图5中的基带芯片18，具体包括以下步骤：
S61：检测第一射频电路和第二射频电路的工作状态。
第一射频电路用于收到第一制式信号，第二射频电路用于收发第二制式信号，因此可以通过检测第一射频电路和第二射频电路的工作状态确定天线的分配情况。
S62：若检测到第二射频电路收发第二制式信号且第一射频电路收发第二频段的第一制式信号时，则控制第一天线收发第二制式信号，控制第二天线接收第二频段的第一制式信号。
由于检测到第二射频电路收发第二制式信号，当第二制式信号为GSM信号时，也就是说检测到用户正在进行语言通话业务过程中，必须要保证该业务的正常进行，因此，需要控制第一天线收发第二制式信号，而第二频段的第一制式信号智能通过第二天线接收。
参见图7为本发明实施例提供的另一种无线终端的天线切换控制方法的流程图，该方法可以应用在如图5所示的无线终端中，该方法的执行主体可以但不限于是如图5中的基带芯片18，具体包括以下步骤：
S71：检测第一射频电路和第二射频电路的工作状态。
S72：若检测到第二射频电路处于空闲状态，则控制第一天线接收第二频段的第一制式信号。
由于第一天线是全频段天线，性能比第二天线优越，因此，可以在第二射频电路处于空闲状态，也就是第一天线处于空闲状态时，通过切换模块切换第一天线接收第二频段的第一制式信号，从而提升第二频段的第一制式信号的性能。
参见图8为本发明实施例提供的另一种无线终端的天线切换控制方法的流程图，该方法可以应用在如图5所示的无线终端中，该方法的执行主体可以但不限于是如图5中的基带芯片18，具体包括以下步骤：
S81：检测第一射频电路和第二射频电路的工作状态。
S82：若检测到第二射频电路收发第二制式信号且第一射频电路收发第二频段的第一制式信号，在第二射频电路收发第二制式信号的通信过程中，控制第一天线收发第二制式信号，控制第二天线接收第二频段的第一制式信号。以及，
S83：在第二射频电路收发第二制式信号的通信空隙时，控制第一天线接收第二频段的第一制式信号。
由于第一天线是全频段天线，性能比第二天线优越，因此，可以在第二射频电路收发第二制式信号的通信空隙，通过切换模块切换第一天线接收第二频段的第一制式信号，从而提升第二频段的第一制式信号的性能。
参见图9为本发明实施例提供的另一种无线终端的天线切换控制方法的流程图，该方法可以应用在如图5所示的无线终端中，该方法的执行主体可以但不限于是如图5中的基带芯片18，具体包括以下步骤：
S91：检测第一射频电路和第二射频电路的工作状态。
S92：若检测到第二射频电路收发第二制式信号且第一射频电路收发第二频段的第一制式信号，判断第一制式信号的类型，如果第一制式信号为数据业务信号，执行S93；如果第一制式信号为语音业务信号，执行S94。
S93：在第二射频电路收发第二制式信号的通信过程中，控制第一天线收发第二制式信号，控制第二天线接收第二频段的第一制式信号；在第二射频电路收发第二制式信号的通信空隙时，控制第一天线接收第二频段的第一制式信号。
S94：控制第一天线仅用于收发第二制式信号，第二天线仅用于接收第二频段的第一制式信号。
对于有些类型的业务，频繁切换天线会导致信号强度出现周期性波动，从而影响业务质量，因此，在进行天线切换控制之前，还需要确定业务类型，对于数据业务，在第二射频电路收发第二制式信号的通信空隙时，可以控制第一天线接收第二频段的第一制式信号；对于语音业务，为了保证业务质量，则一直使用第二天线接收第二频 段的第一制式信号，并且一直使用第一天线接收第二制式信号。可以根据第一制式信号和第二制式信号是数据业务信号还是语言业务信号来确定业务类型，也即是根据第一制式信号和第二制式信号中的具体内容来确定。
参见图10为本发明实施例提供的再一种无线终端的天线切换控制方法的流程图，该方法可以应用在如图5所示的无线终端中，该方法的执行主体可以但不限于是如图5中的基带芯片18，具体包括以下步骤：
S101：检测第一射频电路和第二射频电路的工作状态。
S102：在第一射频电路接收第二频段的第一制式信号的过程中，检测第一天线和第二天线的天线信号强度；
S103：若检测到第一天线的天线信号强度小于设定值，则控制第二天线接收第二频段的第一制式信号；若检测到第二天线的天线信号强度小于设定值且第二射频电路处于空闲状态，则控制第一天线接收第二频段的第一制式信号。
由于用户手持无线终端等等操作会影响天线信号强度，因此，在第一射频电路接收第二频段的第一制式信号的过程中，还可以检测第一天线和第二天线的天线信号强度，并根据检测到的天线信号强度确定是否进行天线切换，从而确保业务质量，提升用户体验。
其中，设定值可以根据实际需要进行设定。
以上是本发明的核心思想，为了使本领域技术人员更好地理解本发明方案，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除、完整地描述，显然，所述描述的实施例仅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做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。
