Description

一种射频通路选择方法及装置、存储介质 技术领域
本发明涉及无线通信领域中信号通路选择技术，尤其涉及一种射频通路选择方法及装置、存储介质。
背景技术
随着无线通信技术的发展，同时具有大量长期演进(Long Term Evolution，LTE)和无线局域网(WIFI)的数据类产品越来越多，例如可作为无线访问接入点(Wireless Access Point，AP)的终端，极大的满足了在没有无线网络覆盖的区域内多个用户的上网需求。
然而，在测试这类终端的无线通信性能时，发现LTE高频和WIFI的相互干扰非常严重。例如，当终端同时支持LTE Band40(2300MHz～2400MHz)和WIFI(2400MHz～2500MHz)时，在2400MHz左右的频段干扰较大。
目前针对上述问题的解决方法主要是用软件将WIFI的低频1～4信道屏蔽，只允许高频5～13信道工作。由于WIFI的低频1～4信道的载波频率从2412MHz～2427MHz，高频5～13信道的载波频率从2432MHz～2472MHz，因而即使屏蔽了WIFI的1～4信道，如果终端注册上LTE的Band40(2300MHz～2400MHz)频段后，在靠近2400MHz的频段仍然存在同频干扰。这样，WIFI的数据上传下载速度还是会下降，而且LTE工作也会受到影响；如果距离稍远则WIFI可能直接断开连接，而且在多个用户接入WIFI时会导致通道堵塞，导致终端的无线通信性能较差。

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同时具有LTE和WIFI的数据类产品，例如：可以为用作AP的终端，诸如具有WIFI热点功能的手机、平板电脑等。本发明实施例的终端包括：射频芯片、高频射频通道、低频射频通道、高频天线、低频天线、可作为低频辅助天线的5G频段高频天线、定向耦合微带线、高频与低频通道馈点、数据读取控制模块以及微带线控制开关。
本发明实施例的高频通道包括但不限于：LTE高频射频通道(从2300MHz开始到2600MHz的射频通道)，和WIFI 2.4G或5G射频通道(WIFI的2.4G和5G的射频通道)，高频天线指的是覆盖了从2.3G到5.8G频段的通信天线，此通信天线可以覆盖LTE的2300MHz到2600MHz频段和WIFI的2.4G和5G频段，低频天线用于覆盖从700MHz到2100MHz频段的通信天线。两副天线分别在低频和高频同时工作，一方面可以避免现有技术中高低频用一副天线而导致某些高频频段隔离度不好的问题，另一方面也可以减少高频的传导损耗。
图1为本发明提供的射频通路选择方法实施例一的流程示意图，如图1 所示，所述方法包括：
步骤101：获取射频芯片的注册频点。
在本步骤中，终端的数据读取控制模块开始读取射频芯片注册到的频点，该频点可能在700MHz～2100MHz范围内，也可能在2300MHz～2600MHz范围内，根据该频点可以划分低频频段和高频频段。
步骤102：确定注册频点的频段范围，根据频段范围控制网络信号选择频道进行发射和接收。
在本步骤中，确定步骤101中终端的数据读取控制模块读取到的频点的频段范围，根据该频段范围，控制网络信号选择不同的频道进行发射和接收。例如可以通过判断的操作，来确定步骤101中的注册处频点的频段范围。本实施例中，根据高低频道频段的范围，将700MHz～2100MHz频段和2300MHz～2600MHz频段的网络信号选择合适的频道进行发射和接收。
这里，若终端的数据读取控制模块读取到射频芯片注册的频点在700MHz～2100MHz范围内，则控制LTE的低频信号通过低频通道馈点输入至低频天线，由低频天线的低频频段例如700MHz～2100MHz频段实现发射和接收；此时，如果WIFI启用，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的2.4G频段实现发射和接收。
若终端的数据读取控制模块读取到射频芯片的注册频点不在低频频段的范围内，而是在2300MHz～2600MHz频段范围内，则射频芯片控制LTE的高频信号通过高频通道馈点输入至高频天线，由高频天线的高频频段例如2300MHz～2600MHz频段实现发射和接收；此时如果WIFI启用，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的5G频段实现发射和接收。
本实施例的射频通路选择方法，通过获取射频芯片注册到的频点，并 确定该注册频点的频段范围，根据该频段范围控制网络信号选择合适的频道进行发射和接收，从而使得LTE的高频信号可以通过高频通道馈点输入至高频天线，由高频天线的高频频段例如2300MHz～2600MHz频段实现发射和接收，且WIFI信号选择高频天线的5G频段实现发射和接收；LTE的低频信号可以通过低频通道馈点输入至低频天线，由低频天线的低频频段例如700MHz～2100MHz频段实现发射和接收，且WIFI信号选择高频天线的2.4G频段实现发射和接收。因此，可以克服LTE高频和WIFI的同频干扰，提高无线通信性能。
图2为本发明提供的射频通路选择方法实施例二的流程示意图，如图2所示，在实施例一的基础上，所述方法还包括：
步骤101：获取射频芯片的注册频点。
步骤101的获取射频芯片的注册频点在实施例一中已经详细说明，此处不再赘述。
步骤103：判断注册频点是否在低频频段的范围内；如果注册频点不在低频频段的范围内，转到步骤104，否则如果注册频点在低频频段的范围内，转到步骤105。
在本步骤中，判断获取到的注册频点是否在低频频段的范围内，本实施中的低频频段指的是700MHz～2100MHz，未来还可以根据频段的扩展或者终端的发展来扩展或者变化，本发明实施例中不限定于此。如果不在低频频段的范围内，则转到步骤104，否则转到步骤105。
步骤104：断开射频通路到低频通道的连接，并接收射频芯片的控制指令，控制指令控制网络信号通过高频通道进行发射和接收，结束本次处理流程。
在本步骤中，若终端的数据读取控制模块读取到射频芯片的注册频点在2300MHz～2600MHz频段范围内，则终端的微带线控制开关断开与低频 通道馈点的连接，用来断开射频通路到低频通道的连接。其中，微带线控制开关为控制射频通路到低频通道馈点的连通开关；该开关闭合时，连通射频通路到低频通道馈点，低频信号可以通过低频通道馈点进入低频天线；开关断开时，断开射频通路到低频通道馈点的连接，低频信号无法通过低频通道馈点进入低频天线。此时，接收射频芯片的控制指令，由于上述已断开射频通路到低频通道的连接，因而，控制指令控制LTE的高频信号通过高频通道馈点输入至高频天线，由高频天线的高频频段例如2300MHz～2600MHz频段实现发射和接收；此时，如果WIFI启用，那么根据终端的数据读取控制模块提供的注册频点信息，射频芯片的WIFI无线模式选择诸如802.11a/n/ac等5G频段，此时，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的5G频段实现发射和接收。
步骤105：保持射频通路到低频通道的连接，并接收射频芯片的控制指令，控制指令控制网络信号分别通过低频通道和高频通道进行发射和接收。
在本步骤中，终端的数据读取控制模块读取到射频芯片注册的频点在700MHz～2100MHz频段范围内，则控制微带线控制开关继续连通到低频通道馈点，保证低频信号通过低频通道馈点进入低频天线；其中，在本步骤中，默认终端的微带线控制开关事先是与低频通道馈点连通的。此时，接收射频芯片的控制指令，以控制终端微带线控制开关继续连通到低频通道馈点，启动LTE低频工作，即：控制指令控制LTE的低频信号通过低频通道馈点输入至低频天线，由低频天线的低频频段例如700MHz～2100MHz频段实现发射和接收；此时，如果WIFI启用，根据数据读取控制模块提供的注册频点信息范围，射频芯片的WIFI无线模式选择诸如802.11b/g/n等2.4G频段，由于此时高频通道也可用，因而，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的2.4G频段实现发射和接收。
本实施例中，通过判断注册频点是否在低频频段的范围内，来选择断 开还是保持射频通路到低频通道的连接；如果不在低频频段的范围内，则断开射频通路到低频通道的连接，从而启动LTE高频工作，即控制指令控制LTE的高频信号通过高频通道馈点输入至高频天线，由高频天线的高频频段例如2300MHz～2600MHz频段实现发射和接收；此时，如果WIFI启用，那么根据终端的数据读取控制模块提供的注册频点信息，射频芯片的WIFI无线模式选择诸如802.11a/n/ac等5G频段，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的5G频段实现发射和接收。如果在低频频段的范围内，则保持射频通路到低频通道的连接，此时启动LTE低频工作，即控制指令控制LTE的低频信号通过低频通道馈点输入至低频天线，由低频天线的低频频段例如700MHz～2100MHz频段实现发射和接收；且由于此时高频通道也可用，射频芯片的WIFI无线模式选择诸如802.11b/g/n等2.4G频段，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的2.4G频段实现发射和接收。因此，在LTE低频和高频工作模式下，均可以克服和WIFI的同频干扰，提高无线通信性能。
图3为本发明提供的射频通路选择方法实施例三的流程示意图，如图3所示，在上述实施例的基础上，所述获取射频芯片的注册频点包括：
步骤1011：终端上电，连通射频通路到低频通道的连接。
在本步骤中，首先终端上电，终端的微带线控制开关连通到低频通道馈点，连通射频通路到低频通道的连接，由于射频通路到高频通道始终是连通的，因而此时所有的通道均连通可用。此处的终端为可作AP的终端，例如具有WIFI热点功能的手机、平板电脑等。
步骤1012：根据网络环境选择射频芯片的初始注册频点并注册。
在本步骤中，射频芯片根据当前网络条件注册在最优频点上，即选择初始注册频点并注册。
步骤1013：预设时间到达后，获取射频芯片的注册频点。
在本步骤中，此处的预设时间是从终端上电开始后的一段时间，例如可以设置为3分钟，该预设时间可用根据用户需求和终端性能进行设置，此处不再限定。由终端的数据读取控制模块计时，在预设时间到达后例如数据读取控制模块从终端上电开始计时3分钟后，开始读取射频芯片的注册频点，取出注册频点的数据。
图4为本发明提供的射频通路选择方法实施例四的流程示意图，如图4所示，在实施例三的基础上，所述方法包括：
步骤1011：终端上电，连通射频通路到低频通道的连接。
步骤1012：根据网络环境选择射频芯片的初始注册频点并注册。
步骤1013：预设时间到达后，获取射频芯片的注册频点。
步骤103：判断注册频点是否在低频频段的范围内；如果注册频点不在低频频段的范围内，则执行步骤106；否则，执行步骤108。
在本步骤中，获取到注册频点后，判断该注册频点是否在低频频段范围内，该低频频段范围例如为700MHz～2100MHz频段，如果不在该低频频段范围内，执行步骤106，即断开射频通路到低频通道的连接；否则转到步骤108，即保持射频通路到低频通道的连接。
步骤106：断开射频通路到低频通道的连接。
步骤107：接收射频芯片的控制指令，控制指令控制网络信号通过高频通道进行发射和接收，执行步骤110。
步骤108：保持射频通路到低频通道的连接。
步骤109：接收射频芯片的控制指令，控制指令控制网络信号分别通过低频通道和高频通道进行发射和接收。
其中，步骤1011至步骤109在上述实施例中已进行详细说明，此处不再赘述。
步骤110：根据预设周期周期性的获取射频芯片的注册信息，判断注册 信息中的信号强度是否小于预设阈值，如果信号强度小于预设阈值，则返回重新根据网络环境选择射频芯片的初始注册频点并注册。
在本步骤中，终端的数据读取控制模块根据预设周期周期性的读取射频芯片的注册信息，预设周期可以设置为1分钟或者其他时间，根据用户需求和终端性能进行设置，并由数据读取控制模块的定时器实现定时。如果数据读取控制模块获取到射频芯片的注册信息中信号达到弱信号的阈值，即信号强度小于某个预设阈值，预设阈值根据用户需求和终端性能进行设置，例如该预设阈值可以为-90dbm，则返回步骤1012射频芯片重新注册网络，并继续执行步骤1013～110；如果未达到弱信号的阈值，则根据预设周期周期性的读取射频芯片的注册信息并继续执行判断注册信息中信号是否为弱信号的过程。
本实施例的射频通路选择方法，初始时终端的微带线控制开关连通到低频通道馈点，连通射频通路到低频通道的连接，保证低频通道和高频通道均可用，然后获取射频芯片的注册频点并判断该注册频点是否在低频频点的范围内；如果不在低频频点的范围内，则断开射频通路到低频通道的连接，控制指令控制LTE的高频信号通过高频通道馈点输入至高频天线，由高频天线的高频频段例如2300MHz～2600MHz频段实现发射和接收，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的5G频段实现发射和接收；否则，保持射频通路到低频通道的连接，启动LTE低频工作，即控制指令控制LTE的低频信号通过低频通道馈点输入至低频天线，由低频天线的低频频段例如700MHz～2100MHz频段实现发射和接收，WIFI信号通过高频通道馈点输入至高频天线，由高频天线的2.4G频段实现发射和接收；并进一步周期性的判断获取到射频芯片的注册信息中的信号强度是否为弱信号，如果是弱信号则返回从射频芯片重新注册网络开始执行，否则继续执行判断注册信息中信号是否为弱信号的过程。因此，可以克服LTE 和WIFI的同频干扰问题，提高无线通信性能。
在本发明的其他实施例中，在实施例二的基础上，所述方法还包括：
如果所述注册频点在所述低频频段的范围内，则连通所述射频通路到低频定向耦合通道的连接；
接收所述射频芯片的控制指令，所述控制指令控制所述低频频段的网络信号通过低频通道和/或低频定向耦合通道进行发射和接收。
这里，如果注册频点在低频频段的范围内，那么还可以连通射频通路到低频定向耦合通道的连接，即通过终端的定向耦合微带线连通到高频的5G天线，这样，低频天线可以利用高频的5G天线作为低频天线的辅助天线来增强低频天线的天线性能。因此，控制指令控制低频频段的网络信号可以通过低频通道的低频天线进行发射和接收，也可以通过定向耦合微带线连通到高频天线的5G频段(作为低频天线的辅助天线)进行发射和接收，或者通过低频通道的低频天线和通过定向耦合通道的低频定向耦合微带线连通到高频天线的5G频段进行发射和接收。

工业实用性
本发明实施例中，通过获取射频芯片的注册频点，确定该注册频点的频段范围，从而可以根据该频段范围来控制网络信号选择不同的频段进行发射和接收，即LTE的高频信号可以通过高频天线的高频频段实现发射和接收，且WIFI信号选择高频天线的5G频段实现发射和接收；LTE的低频信号可以通过低频天线的低频频段实现发射和接收，且WIFI信号选择高频天线的2.4G频段实现发射和接收。该方法能够克服LTE高频和WIFI的同频干扰，提高无线通信性能。
