Description

通信系统的信息传输方法、通信系统及通信设备 技术领域
本发明涉及通信技术领域,特别是涉及一种通信系统的信息传输方法、通信系统及通信设备。
背景技术
随着无线网络技术的不断进步,无线网络中的WiFi技术应用也越来越广泛。为了保证数据由源通信设备通过WiFi传输到目标通信设备的可靠性,尽可能降低数据传输的丢包率,源通信设备向目标通信设备发送数据包后,如果目标通信设备成功接收到数据包,则目标通信设备向源通信设备回复确认(ACK)反馈信息;如果目标通信设备未成功接收到数据包,则向源通信设备回复非确认(NACK)反馈信息,从而触发源通信设备重传数据包。
目前,基于WiFi技术的反馈信息都需要通过一个完整的WiFi数据帧来发送,由于WiFi基于载波侦听多路访问/碰撞避免(Carrier-sense multiple access with collision avoidance,CSMA/CA)来进行信道接入和通信的,每个WiFi数据帧都携带独立的同步头数据来进行通信,一个WiFi数据帧中的同步头数据的数据量较大而反馈信息的数据量较小,从而造成目标通信设备向源通信设备回复反馈信息时效率较低的问题。

具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚,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。
参照图1,图1为本发明实施例提供的一种通信系统的结构框图。该通信系统包括:第一通信设备和第二通信设备,所述第一通信设备包括第一通信模块和第二通信模块,所述第二通信设备包括第三通信模块和第四通信模块,所述第一通信模块和所述第三通信模块基于第一通信协议进行通信,所述第二通信模块和所述第四通信模块基于第二通信协议进行通信。例如,第一通信协议为WiFi协议,第二通信协议为私有协议,第一通信模块为第一通信设备的WiFi模块,第二通信模块为第一通信设备的私有模块,第三通信模块为第二通信设备的WiFi模块,第四通信模块为第二通信设备的私有模块。
基于图1,本发明提供了一种通信系统的信息传输方法。参照图2,图2为本发明实施例提供的一种通信系统的信息传输方法的步骤流程图,该方法包括如下步骤:
步骤201、第三通信模块基于第一通信协议向第一通信模块发送数据包。
步骤202、第二通信模块基于第二通信协议向第四通信模块发送数据包对应的反馈包,反馈包中包括反馈信息,反馈信息用于指示第一通信设备是否成功接收数据包。
其中,基于第二通信协议发送的反馈包中反馈信息所占的数据量 比例大于基于第一通信协议发送的反馈包中反馈信息所占的数据量比例。
需要说明的是,通信系统可以为无人机系统,第一通信设备可以为遥控器,第二通信设备为无人机。或者,第一通信设备为无人机,第二通信设备为遥控器。
本实施例中以通信系统为无人机系统,第一通信设备为遥控器,第二通信设备为无人机为例,即将第二通信设备作为源通信设备,第二通信设备向第一通信设备(将第一通信设备作为目标通信设备)发送数据包为例,则无人机的第三通信模块(第三通信模块例如为无人机的WiFi模块)基于第一通信协议向遥控器的第一通信模块(第一通信模块例如为遥控器的WiFi模块)发送数据包。第一通信模块可以根据数据包的接收信息,生成数据包对应的反馈包,或者,第一通信模块将数据包的接收信息发送给第二通信模块,第二通信模块根据数据包的接收信息生成数据包对应的反馈包。其中,数据包的接收信息包括成功接收数据包和非成功接收数据包,成功接收数据包意味着第一通信设备已收到数据包、且数据包的校验结果正确,非成功接收数据包意味着未收到数据包或者收到的数据包的校验结果错误。
若第一通信模块生成数据包对应的反馈包,则可以将数据包对应的反馈包发送给第二通信模块,由第二通信模块基于第二通信协议向第四通信模块发送数据包对应的反馈包。若由第二通信模块生成数据包对应的反馈包,则第二通信模块可以直接基于第二通信协议向第四通信模块发送数据包对应的反馈包。
由于现有技术中,第一通信设备和第二通信设备之间通过WiFi模块进行通信,例如,将第二通信设备作为源通信设备,将第一通信设备作为目标通信设备,源通信设备(第二通信设备)通过WiFi模块向目标通信设备(第一通信设备)的WiFi模块发送数据包,目标通信设备的WiFi模块基于WiFi协议向源通信设备的WiFi模块发送数据包对应的WiFi数据帧,WiFi数据帧中包括数据包对应的反馈信息,而每个WiFi数据帧都携带独立的同步头数据来进行通信,一个WiFi数据帧中的同步头数据的数据量较大而反馈信息的数据量较小,从而造成目标通信设备基于第一通信协议向源通信设备回复反馈信息时效率较低的问题。而本实施例提供的通信系统的信息传输方法, 第二通信模块基于第二通信协议向第四通信模块发送数据包对应的反馈包,例如第二通信设备的第二通信模块(第二通信模块例如为私有模块)基于第二通信协议向第四通信模块发送数据包对应的反馈包,即目标通信设备并非基于WiFi协议向源通信设备发送数据包对应的反馈包。并且,由于第二通信协议为非WiFi协议,例如Ocusync协议,基于第二通信协议发送的反馈包无需携带WiFi协议中规定的同步头数据,因此,使基于第二通信协议发送的反馈包中反馈信息所占的数据量比例大于基于第一通信协议发送的反馈包中反馈信息所占的数据量比例,从而提高了目标通信设备向源通信设备回复反馈信息时的效率。
可选的,发送数据包对应的反馈包,包括:
发送预设数量的数据包对应的反馈包,预设数量与第一通信模块和第三通信模块之间的通信质量有关。
例如,预设数量为1时,第二通信模块基于第二通信协议向第四通信模块一次发送一个数据包对应的反馈包,该反馈包中的反馈信息用于指示第一通信设备是否成功接收一个数据包。例如,反馈信息为确认信息(ACK信息)的情况下,表示反馈包中的数据包的标识对应的一个数据包被第一通信设备成功接收;反馈信息为非确认信息(NACK信息)的情况下,表示反馈包中的数据包的标识对应的一个数据包未被第一通信设备成功接收。
或者,预设数量大于1,例如,预设数量等于50时,第二通信模块基于第二通信协议向第四通信模块一次发送50个数据包对应的反馈包,该反馈包中的反馈信息的个数可以为一个,例如该反馈包中的反馈信息为确认信息的情况下,表示该50个数据包都被第一通信设备成功接收,若该反馈包中的反馈信息为非确认信息的情况下,表示该50个数据包中有至少一个数据包未被第一通信设备成功接收,需要第二通信设备重新发送该50个数据包。当一次发送多个数据包对应的反馈包的情况下,多个数据包可以对应一个反馈包中的一个反馈信息,一个反馈信息只需要占用一个比特位,从而可以减少发送的反馈信息的数据量,进而提高发送反馈信息时的效率。
可选的,发送预设数量的数据包对应的反馈信息,包括:
当第一通信模块和第三通信模块之间的通信质量满足预设条件 时,发送第一预设数量的数据包对应的反馈包;
当第一通信模块和第三通信模块之间的通信质量不满足预设条件时,发送第二预设数量的数据包对应的反馈包,第一预设数量大于第二预设数量。
当第一通信模块和第三通信模块之间的通信质量满足预设条件时,表示第一通信模块和第三通信模块之间的通信质量较高,此种情况下,可以发送第一预设数量的数据包对应的反馈包,例如,第一预设数量为50,也即反馈包中包括50个数据包对应的反馈信息。当第一通信模块和第三通信模块之间的通信质量不满足预设条件时,表示第一通信模块和第三通信模块之间的通信质量较差,此种情况下,可以发送第二预设数量的数据包对应的反馈包,例如,第二预设数量为1,也即反馈包中包括1个数据包对应的反馈信息。
通信质量较高时,第一通信模块成功接收数据包的概率相对较高,通过在反馈包中反馈较多数据包对应的反馈信息,可以提高反馈效率。然而,在通信质量较低时,第一通信模块成功接收数据包的概率相对较低,如果在反馈包中反馈较多数据包对应的反馈信息,可能会使得第二通信设备重传大量数据包。例如,反馈包中包括50个数据包对应的反馈信息,若第一通信设备未成功接收50个数据包中的至少一个数据包,则这50个数据包对应的反馈信息为非确认反馈信息,从而会导致50个数据包的重传。因此,在通信质量较低时,在反馈包中反馈较少数据包对应的反馈信息,可以有效的减少数据包的大量重传。
可选的,方法还包括:
统计历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例;
当历史反馈包的反馈信息中确认信息所占的个数比例大于第一预设比例阈值,或者非确认信息所占的个数比例小于第二预设比例阈值时,确定第一通信模块和第三通信模块之间的通信质量满足预设条件;
当历史反馈包的反馈信息中确认信息所占的个数比例小于或等于第一预设比例阈值,或者非确认信息所占的个数比例大于或等于第二预设比例阈值时,确定第一通信模块和第三通信模块之间的通信质量不满足预设条件。
可选的,可以预先建立历史反馈包的反馈信息中确认信息所占的 个数比例与上述预设数量之间的对应关系,或者预先建立历史反馈包的反馈信息中非确认信息所占的个数比例与上述预设数量之间的对应关系,示例的,该对应关系可以通过表格或者拟合函数表示。如此,可以实时地调整预设数量,使得该预设数量与通信质量相匹配。
可以由第一通信设备统计历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例,由第一通信设备确定第一通信模块和第三通信模块之间的通信质量是否满足预设条件。或者由第二通信设备统计历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例,由第二通信设备确定第一通信模块和第三通信模块之间的通信质量是否满足预设条件,第二通信设备判断第一通信模块和第三通信模块之间的通信质量是否满足预设条件后,可以将判断结果发送给第一通信设备,从而使第一通信设备基于判断结果,确定第一通信模块和第三通信模块之间的通信质量是否满足预设条件。
可选的,统计历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例,包括:
统计一定时长的时间段内历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例;或者
统计一定数量的历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例。
一定时长的时间段例如为距离当前时间点为预设时长内的时间段,通过统计一定时长的时间段内历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例,可以确定第一通信模块和第三通信模块之间的通信质量是否满足预设条件。
或者,统计一定数量的历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例。例如统计1000个历史反馈包的反馈信息中确认信息所占的个数比例或者非确认信息所占的个数比例。
可选的,数据包的数量为多个,多个数据包包括N组数据包,N为大于或等于1的整数,数据包对应的反馈包为N组数据包对应的反馈包;
针对N组数据包中的任意一组数据包,若有至少一个数据包没有 成功接收,则该组数据包对应的反馈信息为非确认信息;若所有数据包均成功接收,则该组数据包对应的反馈信息为确认信息。
例如,数据包的数量为500个,若25个数据包分为一组,则共分为20组数据包,若该20组数据包中的任意一组数据包中有至少一个数据包没有成功接收,则该组数据包对应的反馈信息为非确认信息。也即通过一个比特位的确认信息指示一组数据包被第一通信设备成功接收,或者通过一个比特位的非确认信息指示一组数据包未被第一通信设备成功接收,因此,可以减少第一通信设备向第二通信设备发送的确认信息或非确认信息的数据量,从而提高反馈信息的发送效率。
需要说明的是,通过WiFi当前传输协议支持的最大速率,例如,该协议下媒体接入控制(MAC,Media Access Control)数据单元(MAC Protocol Data Unit,MPDU)的值P Byte/ms,结合该协议使用的最大传输速率c Byte/ms,可以计算出每1ms需要反馈的反馈信息的bit数量为M=c/P,其中,MAC数据单元指经过WiFi协议封装过的数据帧,每个MPDU数据单元对应1bit的反馈信息。
第一通信设备的第二通信模块发送反馈信息的调度间隔最大为Tms,则可以计算出第一通信设备一次发送最多需要反馈T×M个MPDU的反馈信息,共T×M个bit;
将上面T×M个(例如T等于10,M等于50)bit的反馈信息,按照K个bit(例如K等于25)划分为1组,每K个反馈信息若全部为确认信息,则将K个反馈信息合并为一个确认信息;若K个反馈信息中有至少一个非确认信息,则将K个反馈信息合并一个非确认信息。需要说明的是,第一通信设备和第二通信设备在初始建立连接时就可以先确定合并比例K,这样,将T×M个bit的反馈消息可以压缩到
Figure PCTCN2020096523-appb-000001
其中
Figure PCTCN2020096523-appb-000002
为向上取整运算。则在T等于10,M等于50,K等于25时,可以将500个bit的反馈消息压缩到20个bit。也即500个数据包对应的反馈包中包括20个bit的反馈信息,20个bit的反馈信 息中的一个反馈信息对应一组数据包,步骤202中的数据包对应的反馈包为20组数据包对应的反馈包。
可选的,方法还包括:
第二通信模块基于第二通信协议向第四通信模块发送反馈包对应的多个数据包中第一个数据包和/或最后一个数据包的标识;或者,
第二通信模块基于第二通信协议向第四通信模块发送反馈包对应的N组数据包中每一组数据包中第一个数据包和/或最后一个数据包的标识。
反馈包对应的多个数据包中第一个数据包和/或最后一个数据包的标识可以包括在反馈包中一起发送给第四通信模块。或者,反馈包对应的N组数据包中每一组数据包中第一个数据包和/或最后一个数据包的标识可以包括在反馈包中一起发送给第四通信模块。
当多个数据包包括的N组数据包中的每组数据包中数据包的数量相同的情况下,第二通信模块可以基于第二通信协议向第四通信模块发送反馈包对应的多个数据包中第一个数据包和/或最后一个数据包的标识时,第四通信模块基于一组数据包中包括的数据包的数量、以及该多个数据包中的第一个数据包和/或最后一个数据包的标识,即可以确定每组数据包中包括的每个数据包的标识,从而在第四通信模块收到的反馈包中某个反馈信息为非确认信息的情况下,可以确定该反馈信息对应的一组数据包未被第一通信设备成功接收,因此,第二通信设备可以重传该组数据包中包括的所有数据包。
例如,第二通信模块基于第二通信协议向第四通信模块发送500个数据包对应的反馈包,该500个数据包共包括20组数据包,该反馈包中的反馈信息包括20组数据包中的每组数据包对应的反馈信息,若数据包组1对应反馈信息1、数据包组2对应反馈信息2、以此类推,数据包组20对应反馈信息2。如果该反馈包中的反馈信息1为非确认信息,其余的反馈信息为确认信息,则表示数据包组1中至少有一个数据包未被第一通信设备成功接收,则第二通信设备可以基于数据包组1中的数据包的数量、以及该500个数据包中的第一个数据包和/或最后一个数据包的标识,即可以确定数据包组1中包括的每个数据包的标识(例如基于每组数据包中的数据包的数量25、以及500个数据 包中的第一个数据包的标识0,可以确定数据包组1中包括的所有数据包的标识为标识0至标识24),并基于数据包组1中包括的每个数据包的标识,重新向第一通信设备发送数据包组1中的所有数据包。
当多个数据包包括的N组数据包中的每组数据包中数据包的数量不相同的情况下,第一通信设备的第一通信模块可以给出需要反馈的每组数据包中的第一个数据包和/或最后一个数据包的标识,数据包的标识可以为数据包的编号。由于第一通信设备一次只需反馈T×M个数据包的信息,因此第一通信设备可以向第二通信设备反馈每组数据包中的第一个数据包的标识和/或最后一个数据包的标识,第二通信设备基于一个数据包组中包括的数据包的数量、以及该数据包组中包括的数据包的编号,即可以确定该数据包组中的数据包的编号从哪个编号开始,到哪个编号结束。若第二通信设备收到第一通信设备发送的反馈包中的某个反馈信息为非确认信息,则可以确定该非确认信息对应的数据包组中包括的所有数据包的编号,从而可以重新向第一通信设备发送该非确认信息对应的数据包组中包括的所有数据包。
第二通信模块基于第二通信协议向第四通信模块发送反馈包对应的N组数据包中每一组数据包中第一个数据包和/或最后一个数据包的标识。例如,结合上述举例介绍,也即此种情况下,第二通信模块基于第二通信协议向第四通信模块发送反馈包对应的该20组数据包中每一组数据包中第一个数据包和/或最后一个数据包的标识,当该反馈包中的反馈信息1为非确认信息,其余的反馈信息为确认信息,则表示数据包组1中至少有一个数据包未被第一通信设备成功接收,则第二通信设备可以基于数据包组1中的数据包的数量、以及该数据包组1中的第一个数据包和/或最后一个数据包的标识,即可以确定数据包组1中包括的每个数据包的标识(例如数据包组1中的数据包的数量25、以及数据包组1中的第一个数据包的标识0,可以确定数据包组1中包括的所有数据包的标识为标识0至标识24),并基于数据包组1中包括的每个数据包的标识,重新向第一通信设备发送数据包组1中的所有数据包,即重新发送数据包组1中的25个数据包。
可选的,反馈包中还包括第一个数据包和/或最后一个数据包的标识,第一个数据包和/或最后一个数据包的标识为经过压缩的标识。
现有技术中,第一通信设备的WiFi模块发送反馈信息的调度间隔 最大为Tms,例如,发送调度的周期为10ms,第一通信设备的WiFi模块每ms需要反馈50个反馈信息(即M等于50),一个数据包的编号需要16bit(0~65535),现有技术中若一次传输10×50=500个数据包,则需要传输的反馈信息、500个数据包中的第一个数据包的标识、以及500个数据包中的最后一个数据包的标识所占的数据量等于10×50+2×16=532bit。而本实施例中,若500个数据包中的每组数据包中的数据包的数量相同,且每个数据包组中包括25个数据包,将K=25个bit的反馈信息合并(即将25个数据包对应的25个反馈信息合并为一个反馈信息),则共合并为20个反馈信息,压缩后传输的反馈包中包括该20个反馈信息、500个数据包中的第一个数据包的标识、最后一个数据包的标识所占的数据量=20+2*9=38bit,相对于现有技术中的532个bit,在一定程度上降低了发送的反馈包中的反馈信息和数据包的标识所占的数据量,因此提高了信息传输效率。其中,一个数据包的标识压缩后的数量大小等于
Figure PCTCN2020096523-appb-000003
即T等于10,M等于50时,第一个数据包的标识压缩后的数据量大小等于
Figure PCTCN2020096523-appb-000004
即等于9,同样最后一个数据包的标识压缩后的数据量大小也等于9,因此,反馈包中包括的经过压缩的第一个数据包和/或最后一个数据包的标识的数据量较小,从而可以在一定程度上提高信息传输效率。
由于反馈包中包括的第一个数据包和/或最后一个数据包的标识为经过压缩的标识,因此,进一步降低了反馈包中包的第一个数据包和/或最后一个数据包的标识的数据量,从而提高了第二通信模块向第四通信模块发送的反馈包的效率。
可选的,数据包的数量为一个,数据包对应的反馈包为一个数据包对应的反馈包;
若一个数据包没有成功接收,则一个数据包对应的反馈信息为非确认信息;若一个数据包成功接收,则一个数据包对应的反馈信息为确认信息。
本实施例中,第二通信模块一次向第四通信模块发送一个数据包对应的反馈包,当采用一次向第四通信模块发送一个数据包对应的反馈包时,可以在反馈包中包括的反馈信息为非确认信息的情况下,第二通信设备向第一通信设备只需重新发送非确认信息对应的数据包,即某个反馈包中的反馈信息为非确认信息时,第二通信设备只需向第 一通信设备重新发送该反馈包对应的一个数据包。相对于数据包的数量为多个,数据包对应的反馈包为多个数据包对应的反馈包的情况下,若反馈包中包括的反馈信息为非确认信息时,可以减少第二通信设备向第一通信设备重新发送的数据包的数量。
可选的,反馈包中还包括一个数据包的标识。
可选的,第二通信模块和第四通信模块之间的通信信道包括第一通信信道和第二通信信道,向第四通信模块发送数据包对应的反馈包,包括:
通过第一通信信道向第四通信模块发送数据包对应的反馈包,第一通信信道的可靠性高于第二通信信道的可靠性。
其中,第一通信信道可以为控制信道,第二通信模块可以通过控制信道向第四通信模块发送数据包对应的反馈包。由于第一通信信道的可靠性高于第二通信信道的可靠性,因此通过第一通信信道向第四通信模块发送数据包对应的反馈包,可以在一定程度上提高反馈包被第四通信模块成功接收的概率。
可选的,数据包对应的反馈包包括第一通信设备的介质访问控制层的反馈信息,和/或,第一通信设备的应用层的反馈信息。
可选的,方法还包括:
第一通信模块生成数据包对应的反馈包,并向第二通信模块发送数据包对应的反馈包;或者,
第一通信模块向第二通信模块发送数据包是否成功接收的信息,第二通信模块根据数据包是否成功接收的信息生成数据包对应的反馈包。
可选的,第二通信模块基于第二通信协议向第四通信模块发送数据包对应的反馈包之后,方法还包括:
第四通信模块获取反馈包中的反馈信息;
当反馈信息中包括非确认信息时,第四通信模块向第三通信模块发送非确认信息对应的数据包的标识;
第三通信模块基于标识重新发送非确认信息对应的数据包。
通过第三通信模块基于标识重新发送非确认信息对应的数据包,可以在一定程度上降低第三通信模块基于第一通信协议向第一通信模块发送的数据包的丢包率。
可选的,第四通信模块向第三通信模块发送非确认信息对应的数据包的标识,包括:
当非确认信息对应一个数据包时,第四通信模块向第三通信模块发送非确认信息对应的一个数据包的标识;
当非确认信息对应多个数据包时,第四通信模块向第三通信模块发送非确认信息对应的多个数据包中第一个数据包的标识和/或最后一个数据包的标识。
当非确认信息对应一个数据包时,第四通信模块向第三通信模块发送非确认信息对应的一个数据包的标识,第三通信模块基于第四通信模块发送的非确认信息对应的一个数据包的标识,向第一通信模块重新发送该一个数据包。
当非确认信息对应多个数据包时,第四通信模块向第三通信模块发送非确认信息对应的多个数据包中第一个数据包的标识和/或最后一个数据包的标识,第三通信模块基于第四通信模块发送的非确认信息对应的多个数据包中第一个数据包的标识和/或最后一个数据包的标识,向第一通信模块重新发送该非确认信息对应的多个数据包。
