实施方式
由于高频率的无线电磁波衰减大,而导致实际的网络速率低的问题,本发明提供了一种动态调整射频前端工作模式的方法、装置及移动终端,
本发明在移动终端使用LTE的高频信号时,通过获取移动终端和基站的位置,计算移动终端和基站之间的距离,并在该距离超过移动终端上行可发射的有效信息的最大距离时,开启移动终端的高发射模式,使得移动终端的射频前端工作在高发射模式下,从而确保移动终端在高频下发送的数据能够被基站接收到,以提高基站解调效率,继而解决了现有技术中由于高频率的无线电磁波衰减大,而导致实际的网络速率低的问题。以下结合附图以及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的实施例仅仅用以解释本发明,并不限定本发明。
本发明实施例提供了一种动态调整射频前端工作模式的方法,参见图1,该方法包括:
S101、在移动终端使用LTE的高频信号时,分别获取移动终端的位置信息和基站的位置信息;在本实施例中所述高频信号可为B41,此处的B41对应的频率可为2496至2690MHz。
S102、根据所述移动终端的位置信息和所述基站的位置信息,计算所述移动终端和所述基站之间的距离;
S103、判断该距离是否超过了所述移动终端可发送的上行有效信息的最大距离,如果是,则进入S104;这里的可发送的上行有效信息的最大距离,为移动终端采用其当前功率等级模式发送信息是的最大传输距离。
S104、开启所述移动终端射频前端的高功率等级模式。在步骤104中控制移动终端进入到高功率等级模式,实质上是切换移动终端工作的功率等级模式,从而提升移动终端的发射功率,从而延长移动终端发射的上行信号的传输距离,从而确保基站能够接收到,从而减少基站解调所消耗的时间,提升基站的解调效率,并提升信息传输效率。
在本实施例中所述高功率等级模式可为移动终端的发射功率为23至26dBm的工作模式,但是不局限该发射功率。
也就是说,在移动终端使用LTE的高频信号时,本发明通过获取移动终端和基站的位置,计算移动终端和基站之间的距离,并在该距离超过移动终端上行可发射的有效信息的最大距离时,开启移动终端的高发射模式,使得移动终端的射频前端工作在高发射模式下,从而确保移动终端在高频下发送的数据能够被基站接收到,以提高基站解调效率,继而解决了现有技术中由于高频率的无线电磁波衰减大,而导致实际的网络速率低的问题。
本发明实施例所述获取移动终端的位置信息,包括:
通过移动终端的全球定位系统GPS获取所述移动终端的当前位置信息。
当然,本领域的技术人员也可以通过其他方式来获取移动终端的当前位置信息,如,通过用户输入当前位置信息等等。
可选地,移动终端自带卫星定位接收装置,利用该装置可以定位出终端所处的位置,即经度和纬度。基站在建站时,会记录下卫星定位的位置。此时,获取了移动终端和基站的位置,可以通过经纬度坐标计算出移动终端和基站的相对距离。根据这个距离,终端作出判断。如果移动终端和终端的距离超过了移动终端上行可以发射的有效信息的最大距离,则开启高功率High Power模式,使射频前端PA工作在高功率High Power模式下,提高基站解调效率。避免因为移动终端的上行功率不够导致手机无法和基站进行交互。
本发明实施例所述根据所述移动终端和所述基站位置信息,计算所述移动终端和所述基站之间的距离,包括:
计算移动终端和基站的距离Distance,Distance=R*Arccos(C)*Pi/180,其中,C=sin(MLatA)*sin(MLatB)*cos(MLonA-MLonB)+cos(MLatA)*cos(MLatB),A(MLonA,MLatA)为移动终端经纬度坐标,B(MLonB,MLatB)为
基站纬度坐标。所述R为地球半径,所述Pi为圆周率。所述MLonA为移动终端的经度;所述MLatA为移动终端的纬度。所述MLonB为基站的经度;所述MLatB为基站的纬度。
图2是本发明实施例提供的基站下行的最大有效范围,如图2所示,+23dBm的半径是移动终端在class3等级下的上行链接的最大范围。而移动终端的下行最大有效范围如下图最大的外圈半径。这样上行和下行的距离差了5dB。而+26dBm的移动终端在class2等级下的上行半径比+23dBm多了3dB,也就是说,在class2等级下,基站和移动终端上行半径就只差2dB了,如果移动终端工作在class2等级下,就可以大大提高移动终端的小区边缘性能和用户体验。
本发明实施例所述移动终端可发送的上行有效信息的最大距离为移动终端有效上行距离半径R+23dBm。这里的R+23dBm可为移动终端的射频端的发射功率为23dBm时,预先确定的移动终端发射的上行信号可传输的最大距离。
实施时,本发明实施例所述判断该距离是否超过了所述移动终端可发送的上行有效信息的最大距离,如果是,则开启所述移动终端射频前端的高功率等级模式,包括:
当所述距离大于移动终端有效上行距离半径R+23dBm时,移动终端的射频前端启动第三功率等级模式,即class3模式;
当所述距离小于移动终端有效上行距离半径R+23dBm时,移动终端的射频前端启动第二功率等级模式,即class2模式。
在本实施例中所述第二功率等级模式为高于所述第三功率等级模式的功率等级模式。
在本实施例中,若移动终端工作在所述class3模式时,所述移动终端的发射端的发射功率大于23dBm,在一些情况下,为了节省移动终端的功
耗,所述移动终端工作在class3模式时,所述发射端的最大发射功率可为26dBm。
在本实施例中,若移动终端工作在所述class2模式时,所述移动终端的发射端的发送功率通常不大于23dBm的。在本实施例中可理解为高功率等级模式为第三功率等级模式,移动终端工作在非高功率等级模式时,所述移动终端可能刚工作在第二功率等级模式或其他功率等级模式,一般情况下,若移动终端工作在非高功率等级模式时,的最大发射功率不大于23dBm。
图3是本发明实施例提供的一种动态调整射频前端工作模式的方法的流程示意图,下面将结合图3对本发明所述的方法进行详细的解释和说明:
本发明所使用的设备包括:移动终端一台,带有GPS模块以及拥有class3等级的射频芯片。
S301、根据GPS模块获取移动终端的经纬度坐标A(MLonA,MLatA);
可选为,通过移动终端上的GPS模块,获取移动终端的经纬度坐标A(MLonA,MLatA)。
S302、读取基站位置信息B(MLonB,MLatB);
基站在建站时,会记录下经纬度坐标B(MLonB,MLatB)
S303、根据A和B的经纬度坐标,计算出移动终端距离基站的距离Distance;
其中,C=sin(MLatA)*sin(MLatB)*cos(MLonA-MLonB)+
cos(MLatA)*cos(MLatB)
Distance=R*Arccos(C)*Pi/180
S304、判断移动终端和基站的距离Distance与class 3功率等级的终端有效上行距离R+23dBm的大小,如果,Distance<R+23dBm,则进入S305,否则,进入S306;
S305、将移动终端切换到射频前端的class3模式;
S306、将移动终端切换到射频前端的class2模式。
对比+23dBm UL的半径R+23dBm。当Distance<R+23dBm时,移动终端的上行信号强度可以保证鉴权的要求不会影响下行链路性能,下行链路可以得到足够高的吞吐率。
移动终端切换到class3功率等级模式,降低功耗,提升电池续航。
当Distance>R+23dBm时,移动终端的上行信号强度受到鉴权的限制,导致吞吐率下降。移动终端在小区边缘时使用更保守的调试技术和编码方式,以便eNB可以顺利接受并解调移动终端的信号。
由于LTE是一个上行受限的系统,移动终端的上行功率衰减严重,这导致基站小区的覆盖率相比WCDMA和CDMA2000要差很多,因此,需要更多的基站数量去保证移动网络的覆盖。这无疑大大增加了运营商的前期投入。而当采用本发明所述的方法后,可在不增加额外基站资源投入的情况下,可以有效提高30%小区的覆盖率,所以本发明可大大节约运营商的前期投入。
本发明实施例提供了一种动态调整射频前端工作模式的装置,参见图4,包括:
获取单元,配置为在移动终端使用LTE的高频信号时,分别获取移动终端的位置信息和基站的位置信息;
计算单元,配置为根据所述移动终端的位置信息和所述基站的位置信息,计算所述移动终端和所述基站之间的距离;
判断单元,配置为判断该距离是否超过了所述移动终端可发送的上行有效信息的最大距离,如果是,则开启所述移动终端射频前端的高功率等级模式。这里的可发送的上行有效信息的最大距离,为所述移动终端的当前功率等级模式对应的上行有效信息的最大距离,通过开启高功率等级模式,提升所述移动终端射频端的发射功率。
即,本发明在移动终端使用LTE的高频信号时,本发明通过获取单元获取移动终端和基站的位置,由计算单元计算移动终端和基站之间的距离,并在判断单元确定该距离超过移动终端上行可发射的有效信息的最大距离时,开启移动终端的高发射模式,使得移动终端的射频前端工作在高发射模式下,从而确保移动终端在高频下发送的数据能够被基站接收到,以提高基站解调效率,继而解决了现有技术中由于高频率的无线电磁波衰减大,而导致实际的网络速率低的问题。
可选地,本发明所述获取单元,还配置为通过移动终端的全球定位系统获取所述移动终端的当前位置信息。
当然,本领域的技术人员也可以通过其他方式来获取移动终端的当前位置信息,如,通过用户输入当前位置信息等等。
实施时,本发明实施例所述计算单元还用于,计算移动终端和基站的距离Distance,Distance=R*Arccos(C)*Pi/180;
C=sin(MLatA)*sin(MLatB)*cos(MLonA-MLonB)+cos(MLatA)*cos(MLatB),A(MLonA,MLatA)为移动终端经纬度坐标,B(MLonB,MLatB)为基站纬度坐标。这里的,所述R为地球半径,所述Pi为圆周率
可选地,本发明所述判断单元,还配置为当所述距离大于移动终端有效上行距离半径R+23dBm时,移动终端的射频前端启动第三功率等级模式;当所述距离小于移动终端有效上行距离半径R+23dBm时,移动终端的射频前端启动第二功率等级模式。
图2是本发明实施例提供的基站下行的最大有效范围,如图2所示,+23dBm的半径是移动终端在class3等级下的上行链接的最大范围。而移动终端的下行最大有效范围如下图最大的外圈半径。这样上行和下行的距离差了5dB。而+26dBm的移动终端在class2等级下的上行半径比+23dBm多了3dB,也就是说,在class2等级下,基站和移动终端上行半径就只差2dB
了,如果移动终端工作在class2等级下,就可以大大提高移动终端的小区边缘性能和用户体验。
可选地,对比+23dBm UL的半径R+23dBm。当Distance<R+23dBm时,移动终端的上行信号强度可以保证鉴权的要求不会影响下行链路性能,下行链路可以得到足够高的吞吐率。
移动终端切换到class3功率等级模式,降低功耗,提升电池续航。
当Distance>R+23dBm时,移动终端的上行信号强度受到鉴权的限制,导致吞吐率下降。移动终端在小区边缘时使用更保守的调试技术和编码方式,以便eNB可以顺利接受并解调移动终端的信号。
