Description

一种多模终端 技术领域
本发明涉及通信技术领域，尤其涉及一种多模终端。
背景技术
随着无线通信技术的发展，出现了越来越多的无线通信制式，如：全球移动通信系统(global system of mobilecommunication，GSM)、全入网通信系统(Total Access Communication System，TACS)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址系统(Code Division Multiple Access，CDMA)、码分多址2000系统(CDMA 2000)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、长期演进(Long Term Evolution，LTE)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMax)、无线局域网(Wireless Local Area Networks，WLAN)、蓝牙(Bluetooth)等等，这些通信制式在传输速率、覆盖范围、建网成本、安全性等各方面各有优缺点。为了能够兼顾各种通信制式的优点，近年来出现了综合多种通信制式于一体的终端，该终端可称为多模终端，可同时支持多种通信制式，兼顾多个网络。
通常，多模终端会配置多个数据传输机芯片(modem)以及多个天线，其中，所述数据传输机芯片可以对应一个通信制式，用于在该通信制式下进行数据传输和通信，且在通信过程中会根据需要选择最佳天线来收发信号。为了使每个数据传输机芯片均可选择出最佳天线，现有技术中每个数据传输机芯片上均配置有用于选择最佳天线的天线选择模块；例如，以图1所示的双待手机方式SVLTE(Simultaneous Voice and LTE)为例，LTE数据传输机芯片上配置一个天线选择模块，CDMA数据传输机芯片上配置一个天线选择模块，LTE数据传输机芯片和CDMA数据传输机芯片分别与一个射频 收发机相连接，射频收发机分别与双刀双掷开关(double-pole double-throw，DPDT)连接，DPDT与天线连接，用来连通数据传输机芯片与最佳天线之间的通道；若LTE数据传输机芯片中的天线选择模块计算出LTE制式下当前最佳天线为天线1，则控制DPDT将LTE数据传输机芯片与天线1连通，使LTE数据传输机芯片产生的信号经过射频收发机变为LTE射频信号后，通过天线1进行收发；同理，当CDMA数据传输机芯片中的天线选择模块计算出CDMA制式下当前最佳天线为天线1，则控制DPDT将CDMA数据传输机芯片与天线1连通，使CDMA数据传输机芯片产生的信号经过射频收发机变为CDMA射频信号后，通过天线1进行收发。
在实现本发明实施例的过程中，发明人发现现有技术中至少存在如下问题：现有技术中的多模终端，为了支持多种通讯制式均可选择出最佳天线，需要在每个制式的数据传输机芯片上均配置天线选择模块，导致开发成本高。

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，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。
需要说明的是，本发明所说的多模终端能够同时支持多种制式，该多种制式可以包括：全球移动通信系统(global system of mobilecommunication，GSM)、全入网通信系统(Total Access Communication System，TACS)、宽带码分多址系统(Wideband Code  Division Multiple Access，WCDMA)、码分多址系统(Code Division Multiple Access，CDMA)、码分多址2000系统(CDMA 2000)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、长期演进(Long Term Evolution，LTE)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMax)、无线局域网(Wireless Local Area Networks，WLAN)、蓝牙(Bluetooth)制式中的至少两种，其中，随着通信技术的不断发展，所述多模终端还可以支持新增的其他类型的制式。
实施例一
图2示出了本发明实施例提供的一种多模终端的结构图，如图2所示，该多模终端可以包括：第一数据传输机数据传输机芯片10、至少一个第二数据传输机芯片20、与所有数据传输机芯片相连接的开关模块30、与所述开关模块30连接的至少两个天线；
其中，数据传输机芯片可以为单一制式通信芯片；还可以为一群制式集合的通信芯片，例如集合LTE、WCDMA以及GSM制式的通信芯片；所述开关模块30可以为能够连通数据传输机芯片和任一条天线的多选开关，例如，可以为一双刀双掷开关。
所述第一数据传输机芯片10可以为多模终端中的任一数据传输机芯片，支持第一通信制式，包括天线选择模块101，用于为第一数据传输机芯片从所述至少两个天线中选择出最佳天线，并控制所述开关模块将所述第一数据传输机芯片与所述第一数据传输机芯片的最佳天线连通。
所述第二数据传输机芯片20可以为多模终端中的除第一数据传输机芯片之外的其他任一数据传输机芯片，可支持第二通信制式，该数据传输机芯片与现有的数据传输机芯片相比，不具备用于控制开关模块连通第二数据传输机芯片与第二数据传输机芯片的最佳天线的天线选择模块，至少可以包括：测量单元2011，用于测量所述第二数据传输机芯片收发信号的相关参数值，所述相关参数值用于确定所述第二数据传输机芯片的最佳天线。
可选的，测量单元2011可以周期性的测量第二数据传输机芯片收发的信号的相关参数值；所述相关参数值可以包括：信号的强度、信号的质量等等，且不同制式下的相关参数值是不同的，如LTE制式下的相关参数值可能会是参考信号接收功率(Reference Singnal Receiving Power，RSRP)、参考信号结构质量(Reference Singnal Receiving Quality，RSRQ)、块差错率(Block Error，BLER)等，GSM制式下的相关参数值可能是接收的信号强度指示(Received Signal Strength Indication，RSSI)。
虽然，第二数据传输机芯片不具备用于控制开关模块连通第二数据传输机芯片与第二数据传输机芯片的最佳天线的天线选择模块，但可以由第一数据传输机芯片作为代理芯片，来控制开关模块导通第二数据传输机芯片与第二数据传输机芯片的最佳天线，具体实现如下：
所述第二数据传输机芯片将所述第二数据传输机芯片收发信号的相关参数值发送给第一数据传输机芯片；具体地，可通过所述第一数据传输机芯片与所述第二数据传输机芯片之间的通信通道传输。所述第二数据传输机芯片收发信号的相关参数值在第一数据传输机芯片中传输到所述天线选择模块101。
所述第一数据传输机芯片的所述天线选择模块101，还用于根据所述第二数据传输机芯片收发信号的相关参数值，在所述至少两个天线中确定所述第二数据传输机芯片的最佳天线，并控制所述开关模块将所述第二数据传输机芯片与所述第二数据传输机芯片的最佳天线连通。
具体地，如图2A所示的多模终端，设置在第一数据传输机芯片上的天线选择模块101可以包括：第一测量单元1011、第一配置单元1012以及第一执行单元1013，并通过这些单元为第一数据传输机芯片选择出最佳天线，控制所述开关模块将所述第一数据传输机芯片与所述第一数据传输机芯片的最佳天线连通，以及确定所述第二数据传输机芯片的最佳天线，并控制所述开关模块将所述第二 数据传输机芯片与所述第二数据传输机芯片的最佳天线连通。
所述第一测量单元1011，用于测量所述第一数据传输机芯片收发信号的相关参数值；
所述第一配置单元1012，用于根据所述第一数据传输机芯片收发信号的相关参数值为所述第一数据传输机芯片配置最佳天线；以及根据第二数据传输机芯片收发的信号的相关参数值，为所述第二数据传输机芯片配置最佳天线；
第一执行单元1013，用于控制所述开关模块将所述第一数据传输机芯片与所述第一数据传输机芯片的最佳天线连通；以及控制所述开关模块将所述第二数据传输机芯片与所述第二数据传输机芯片的最佳天线连通。
如图2A所示，第二数据传输机芯片包括：测量单元2011，用于测量所述第二数据传输机芯片收发信号的相关参数值。
所述多模终端还可以包括：通信接口40，可以位于数据传输机芯片之间，作为数据传输机芯片之间的通信信道，实现数据传输机芯片之间的数据传输；此外，本发明还可以通过其他方式在数据传输机芯片之间建立通信信道，如在每个数据传输机芯片上设置通信接口，第一数据传输机芯片上的通信接口与其他数据传输机芯片上的通信接口建立连接，形成数据传输机芯片之间通信通道。本发明实施例对此不进行限制，本发明实施例中仅以在数据传输机芯片之间通过通信接口40建立通信信道为例进行说明。
所述通信接口40，用于将所述第二数据传输机芯片收发信号的相关参数值发送给第一数据传输机芯片10。
第二数据传输机芯片通过所述通信接口40将所述第二数据传输机芯片收发信号的相关参数值发送给第一数据传输机芯片10，第一数据传输机芯片中所述第二数据传输机芯片收发信号的相关参数值传输到第一配置单元1012。
可选的，为了避免测量单元2011测量到第二数据传输机芯片的相关参数值后，所述第二数据传输机芯片的相关参数值立即通过通 信接口40上报给所述第一数据传输机芯片导致的信令频繁的问题，本发明实施例中，如图2B所示，所述第二数据传输机芯片20还可以包括：
准则运算单元2012，用于接收所述测量单元2011测量的所述第二数据传输机芯片收发信号的相关参数值，判断所述第二数据传输机芯片收发信号的相关参数值是否符合预设条件，当确定所述第二数据传输机芯片收发信号的相关参数值符合预设条件，向所述第一数据传输机芯片发送所述第二数据传输机芯片收发信号的相关参数值；
具体地，可通过所述通信接口40，将所述第二数据传输机芯片收发信号的相关参数值向第一数据传输机芯片发送。所述第二数据传输机芯片收发信号的相关参数值在第一数据传输机芯片中传输至所述第一配置单元1012。
其中，所述预设条件可以根据数据传输机芯片对应的通信制式进行设置。例如，若第二数据传输机芯片为LTE芯片，可以定义LTE制式下的预设条件为RSRP小于RSRP门限值-90dBm，当准则运算单元确定测量到的RSRP小于低于该门限值时，才将相关参数值传送至第一数据传输机芯片，由第一配置单元1012根据相关参数值为第二数据传输机芯片配置最佳天线。
如此，与现有技术相比，第二数据传输机芯片不再具备用于控制开关模块连通第二数据传输机芯片与第二数据传输机芯片的最佳天线的天线选择模块，而是通过第一数据传输机芯片上的天线选择模块来控制第二数据传输机芯片与最佳天线的导通，减少了第二数据传输机芯片的设计成本，进一步大大降低了多模终端的生产成本与开发成本。
此外，为了更准确地为第二数据传输机芯片配置最佳天线，第二数据传输机芯片的最佳天线还可以由本发明提供的另一种多模终端中第二数据传输机芯片内部的单元进行配置，下面通过实施例二对本发明实施例提供的另一种多模终端进行介绍：
