技术领域

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。
本发明实施例公开了一种数据传输方法,应用于无线链路机,所述无线链路机在系统通信链路中设定多个数据传输通道,并将所述多个数据传输通道的标识信息按照设定的先后顺序存储在数据传输通道复用周期表中;其中,所述多个数据传输通道的数量不小于3个;所述标识信息包括收发频点标识及时隙标识;参见图1所示,该方法包括:
S101、接收所述系统通信链路中传输的数据;
具体的,无线链路机在系统通信链路中收发数据都是通过事先已设定好的数据传输通道进行的。所述接收系统通信链路中传输的数据,表示无线链路机接收所述多个数据传输通道中的数据。所述数据可以是用户端发送的数据,也可以是基站发送的数据,还可以是另一个无线链路机发送的数据。由于一个无线链路机发送信息只能占用一个数据传输通道,因此,无线链路机接收一个数据传输通道中的数据,即是无线链路机接收了占用该数据传输通道发送数据的 无线链路机、用户端或基站在系统通信链路中发送的数据。
需要说明的是,现有技术中的警用数字集群系统的带宽为12.5k,本发明实施例所述系统通信链路的带宽不仅限于上述现有技术带宽,而是可以根据使用需求,扩大带宽范围。例如,本发明实施例中所述系统通信链路带宽可以为25k,相当于现有技术的两个警用数字集群系统的带宽。进一步的,还可以根据需求或条件允许,设置更大的带宽作为系统通信链路。
S102、识别接收所述数据的数据传输通道;
具体的,为了达到下一无线链路机不干扰上一无线链路机收发数据信息的目的,需要保证所述下一无线链路机与所述上一无线链路机占用不同的数据传输通道发送数据。当无线链路机接收到系统通信链路中的数据并将所述数据发送出去之前,无线链路机需要首先知道是从哪个数据传输通道接收的所述数据,以便于选择不同于接收所述数据的数据传输通道的另一个数据传输通道来发送所述数据。
具体的,无线链路机在设定数据传输通道时,是按照收发频点和时隙来设定的。同样的,无线链路机按照每个数据传输通道的频点和时隙不同,以每个数据传输通道的频点和时隙分别对每个数据传输通道进行标识,然后将所有数据传输通道的标识信息按先后顺序存储到数据传输通道复用周期表中。无线链路机通过识别接收所述数据的频点和时隙,就可以确定是通过哪个数据传输通道接收的所述数据。
S103、根据所述接收所述数据的数据传输通道,将所述数据传输通道复用周期表中的,所述接收所述数据的数据传输通道的下一个数据传输通道,设定为用于发送所述数据的数据传输通道;
具体的,在每一个无线链路机中,都存储有相同的数据传输通道复用周期表。所述数据传输通道复用周期表中按先后顺序存储系统通信链路中的所有数据传输通道的标识信息。每一个无线链路机在识别接收所述数据的数据传输通道之后,从数据传输通道复用周期表中找到所述接收所述数据的数据传输通道,然后将所述接收所述数据的数据传输通道的下一个数据传输通道作为发送所述数据的数据传输通道。所有的无线链路机都按照本发明实施例所述的方法选择发送数据的数据传输通道,达到所有无线链路机有序占用数据传输通道的效果,无线链路机之间不会产生干扰。所述多个数据传输通道的数量越多,在 实现无线链路机延伸覆盖时,无线链路机选择数据传输通道的空间就越大,满足了无线链路机对延伸链路的多样化选择需求。并且,由于数据传输通道的数量为多个(大于3个),无线链路机选择数据传输通道空间较大,能够避免相邻无线链路机之间的干扰,利于实现无线链路机无限延伸覆盖的目的。
需要说明的是,当多个无线链路机采用星形组网或混合组网方式构建自组链路延伸覆盖系统时,在某一个无线链路机中可能发生同时接收到其他多个无线链路机占用多个相邻的数据传输通道发送的数据的情况。此时,无线链路机在选择发送接收到的数据的数据传输通道时,要进一步考虑选择没有被上一个无线链路机占用的数据传输通道。也就是说,要在选择未被占用的数据传输通道的前提下,选择接收数据的数据传输通道的下一个数据传输通道,作为发送数据的数据传输通道。
S104、通过所述用于发送所述数据的数据传输通道,发送所述数据。
显而易见的,无线链路机发送数据的数据传输通道是按照一定的规律从数据传输通道复用周期表中选择的,因此,在所有数据传输通道的一个复用周期内,所有的无线链路机发送数据的数据传输通道不会重复,也就是说无线链路机发送的信号不会产生相互干扰,实现了无线链路机多级延伸覆盖。
本发明提出的数据传输方法,应用于无线链路机,所述无线链路机在系统通信链路中设定多个数据传输通道,并将所述多个数据传输通道按照先后顺序存储在数据传输通道复用周期表中;所述无线链路机在接收系统通信链路中的数据后,识别接收所述数据的数据传输通道;然后根据所述接收所述数据的数据传输通道,将所述数据传输通道复用周期表中的,所述接收所述数据的数据传输通道的下一个数据传输通道,设定为用于发送所述数据的数据传输通道;并通过所述用于发送所述数据的数据传输通道,发送所述数据。本发明技术方案中,无线链路机将通信链路划分为多个数据传输通道,多个无线链路机按照设定顺序占用通道来传输数据,互不干扰,满足了多级延伸覆盖需求。
可选的,在本发明的另一个实施例中,所述在系统通信链路中设定多个数据传输通道,包括:
将系统通信链路带宽中的,设定的不同收发频点上的所有无线子帧的第一时隙及所有无线子帧的第二时隙,分别设定为数据传输通道。
具体的,本发明实施例在系统通信链路带宽中设定多个不同的收发频点, 打破了传统技术方案中收发频点单一的局限性。在每个不同的收发频点上,将所有无线子帧的第一时隙和第二时隙分别设定为数据传输通道,实现了数据传输通道的多样化,为无线链路机选择延伸链路提供了更大的选择空间,能够满足无线链路机对延伸链路的多样化选择需求。进一步地,由于不同无线链路机选择的数据传输通道不同,相互之间不会产生干扰,能够实现多级延伸覆盖。
需要说明的是,当无线链路机所占用的系统通信链路中的无线子帧有多个时隙时,按照本发明实施例技术方案的处理方法,分别将设定收发频点上的所有无线子帧的相同的时隙设定为一个数据传输通道,得到多个数据传输通道,用于供无线链路机复用。例如,系统通信链路中的无线子帧有N个时隙,则将设定收发频点上的所有无线子帧的第1时隙、所有无线子帧的第2时隙…所有无线子帧的第N时隙分别设定为一个数据传输通道,得到多个数据传输通道。
可选的,在本发明的另一个实施例中,所述将系统通信链路带宽中的,设定的不同收发频点上的所有无线子帧的第一时隙及所有无线子帧的第二时隙,分别设定为数据传输通道,参见图2所示,包括:
S201、将系统通信链路带宽划分为多个子带宽;
具体的,每一个数据传输通道都要占用相应的带宽,本发明实施例在设定不同频点的数据传输通道时,首先对系统通信链路进行划分,划分出的子带宽用于数据传输通道传输数据。
需要说明的是,为了保证在系统通信链路扩展的同时,业务数据也同时进行扩展,本发明实施例将系统通信链路带宽平均划分为多个子带宽,且所述子带宽的带宽为12.5k的整数倍,优选地,划分成最小12.5k的子带宽。也就是说,在本发明技术方案中,系统通信链路的带宽设定为最小带宽12.5k的整数倍,以便于进行子带宽的划分,保证业务数据的正常传输。
S202、在每一个子带宽内,分别设定一个收发频点;
具体的,在每一个子带宽内,分别设定一个收发频点,用于标识所述收发频点所在的子带宽。当无线链路机选定某一个设定的频点发送数据时,实际上是无线链路机在所选择的频点所在的子带宽内发送数据。
S203、分别将每个收发频点上的所有无线子帧的第一时隙,设定为一个数据传输通道,以及分别将每个收发频点上的所有无线子帧的第二时隙,设定为 一个数据传输通道。
具体的,警用数字集群系统采用时分双工模式发送数据,即在无线子帧的两个时隙上周期轮换发送数据。本发明实施例根据上述工作模式来设定数据传输通道。对于某一个收发频点,将该频点上的所有无线子帧的第一时隙,作为一个数据传输通道;同时,将该频点上的所有无线子帧的第二时隙,作为一个数据传输通道。这样,在每一个收发频点上,都设定了两个数据传输通道,对于所有划分的收发频点,都执行上述设定,得到多个数据传输通道。
需要说明的是,当警用数字集群系统的工作模式或无线帧结构发生变化,无线子帧包含单个或多个时隙时,采用本发明实施例技术方案的处理方法,分别将设定收发频点上的所有无线子帧的相同的时隙设定为一个数据传输通道,同样能够得到多个数据传输通道。进一步地,无线链路机按设定顺序复用所述多个数据传输通道,实现多级延伸覆盖。
例如,在本发明实施例中,假设系统通信链路的带宽为25k,划分成两个子带宽,每个子带宽12.5k;在一个12.5k子带宽内设定F1为收发频点,在另一个12.5k子带宽中设定F2为收发频点;对于F1,将F1频点上的所有无线子帧的第一时隙S1设定为一个数据传输通道,以及将F1频点上的所有无线子帧的第二时隙S2设定为一个数据传输通道,得到数据传输通道F1S1和F1S2。同样的,对于F2,可以设定数据传输通道F2S1和F2S2。
按照如图3所示的规律,将F1S1、F1S2、F2S1、F2S2存储到数据传输通道复用周期表中,无线链路机占用数据传输通道时,按照F1S1→F1S2→F2S1→F2S2的顺序占用。具体如图4所示,多个无线链路机混合组网时,按照规定好的F1S1→F1S2→F2S1→F2S2的顺序占用数据传输通道,实现了多跳延伸覆盖。
可选的,在本发明的另一个实施例中,所述识别接收所述数据的数据传输通道,包括:
识别接收所述数据的数据传输通道的收发频点和时隙。
具体的,本发明实施例设定数据传输通道时,是以警用数字集群系统的工作模式为基础,根据收发频点和时隙来设定的,不同的收发频点和时隙的组合设定为不同的数据传输通道。并且,无线链路机以数据传输通道的频点和时隙对数据传输通道进行标识,并将标识信息进行保存。因此,能够区分不同的数 据传输通道的标识仅有数据传输通道所在的收发频点和时隙。因此,无线链路机识别接收所述数据的数据传输通道时,识别所述数据传输通道的收发频点和时隙即可。
可选的,在本发明的另一个实施例中,所述将所述多个数据传输通道的标识信息按照设定的先后顺序存储在数据传输通道复用周期表中,包括:
按照所述数据传输通道的标识信息中的时隙标识交替变化的规则,将所述多个数据传输通道的标识信息按照先后顺序存储在数据传输通道复用周期表中。
具体的,在PDT系统通信链路中,无线链路机通过第一时隙接收数据后,要通过第二时隙将数据发送出去。也就是说,无线链路机在占用数据传输通道时,要保证占用的数据传输通道的时隙不同。为了便于无线链路机选择数据传输通道时满足上述要求,在存储所述多个数据传输通道时,按照所述数据传输通道的标识信息中的时隙标识交替变化的规则存储。这样在无线链路机从所述数据传输通道复用周期表中顺序选择并占用数据传输通道时,能够达到所占用的数据传输通道的时隙不同的有益效果。
可选的,在本发明的另一个实施例中,所述将所述多个数据传输通道的标识信息按照设定的先后顺序存储在数据传输通道复用周期表中,包括:
按照所述数据传输通道的标识信息中的时隙标识交替变化,并且收发频点标识从小到大依次变化的规则,将所述多个数据传输通道中符合所述规则的所有数据传输通道的标识信息,依次存储到数据传输通道复用周期表中。
例如,假设对于某一频带带宽,按照本发明实施例技术方案,将该频带带宽划分为N个子信道,同时为每个子信道分别设定收发频点,则得到上述频带带宽内的收发频点包括:F(1)、F(2)…F(N),N>1。对于每一收发频点,分别将该收发频点上的所有无线子帧的第一时隙设定为一个数据传输通道,以及将该收发频点上的所有无线子帧的第二时隙设定为一个数据传输通道,得到每一收发频点上的两个数据传输通道,例如标识信息为F1S1、F1S2、F2S1、F2S2…FNS1、FNS2的数据传输通道。
基于以上信道划分,一种可选的数据传输通道标识信息的存储方式是:按照数据传输通道的标识信息中的时隙标识交替变化,并且收发频点标识从小到大变化的规则,将上述多个数据传输通道的标识信息按照先后顺序存储在数据 传输通道复用周期表中。
参见图7-图10所示,分别列举了当子信道个数为N=2、3、4、5时,所构成的数据传输通道及占用顺序图,图中箭头所指即为数据传输通道被占用的次序,也就是数据传输通道的标识信息在数据传输通道复用周期表中存储的先后顺序。例如,参见图8所示,当频带带宽被划分为F1、F2、F3三个收发频点时,结合各个收发频点上的时隙S1和S2,可得到数据传输通道F1S1、F1S2、F2S1、F2S2、F3S1、F3S2。将这些数据传输通道的标识信息存储到数据传输通道复用周期表中时,按照数据传输通道的标识信息中的时隙标识交替变化,并且收发频点标识从小到大变化的规则进行存储,即按照F1S1、F2S2、F3S1的顺序存储,当存储到最后一个收发频点所构成的数据传输通道标识信息时,按照上述规则返回第一个收发频点所构成的数据传输通道,进行标识信息存储,直到将满足上述存储规则的所有数据传输通道的标识信息都存储到数据传输通道复用周期表中。即,在存储F1S1、F2S2、F3S1后,继续存储F1S2、F2S1、F3S2,此时已经按照上述规则,将数据传输通道标识信息存储完毕。
对比图7-图10可以发现,当为频带带宽划分子信道数量N不同时,存储的可用数据传输通道数量,即频点/时隙不重复的最大跳数随着N的奇偶性变化而变化。当N为偶数时,存储的可用数据传输通道数量,即频点/时隙不重复的最大跳数为N;当N为奇数时,存储的可用数据传输通道数量,即频点/时隙不重复的最大跳数为2N。当子信道个数为3时,占用频点较少且不重复最大跳数较大,在实际使用中性价比较高。
可选的,在本发明的另一个实施例中,所述将所述数据传输通道复用周期表中的,所述接收所述数据的数据传输通道的下一个数据传输通道,设定为用于发送所述数据的数据传输通道,包括:
当所述接收所述数据的数据传输通道为所述数据传输通道复用周期表中存储的最后一个数据传输通道时,将所述数据传输通道复用周期表中,在所述接收所述数据的数据传输通道之前的,与所述接收所述数据的数据传输通道至少间隔一个数据传输通道,且与所述接收所述数据的数据传输通道的标识信息的时隙标识不同的数据传输通道,设定为用于发送所述数据的数据传输通道。
具体的,当上一个无线链路机已经占用了数据传输通道复用周期表中的最后一个数据传输通道发送数据时,无线链路机按照先前设定的规则,选择最后 一个数据传输通道的下一个数据传输通道时,由于没有数据传输通道可供选择,而导致选择失败。在这种情况下,本发明技术方案设定,无线链路机将所述最后一个数据传输通道之前的,与所述最后一个数据传输通道至少间隔一个数据传输通道的数据传输通道设定为用于发送数据的数据传输通道。并且,为了保证无线链路机接收数据的时隙与发送数据的时隙不同,本发明实施例同时要求无线链路机选择的数据传输通道的时隙与所述最后一个数据传输通道的时隙不同。
可选的,在本发明的另一个实施例中,所述将所述数据传输通道复用周期表中,在所述接收所述数据的数据传输通道之前的,与所述接收所述数据的数据传输通道至少间隔一个数据传输通道,且与所述接收所述数据的数据传输通道的标识信息的时隙标识不同的数据传输通道,设定为用于发送所述数据的数据传输通道,包括:
将所述数据传输通道复用周期表中的第一个数据传输通道,设定为用于发送所述数据的数据传输通道。
具体的,在本发明实施例中,由于对数据传输通道的存储是按照数据传输通道的时隙交替变化的规律存储的。每个收发频点上有两个时隙不同的数据传输通道,也就是说,所述多个数据传输通道的数量为偶数个。由此可见,在数据传输通道复用周期表中的第一个数据传输通道与最后一个数据传输通道的时隙不同,选择第一个数据传输通道能够满足无线链路机接收数据与发送数据的时隙不同的要求。并且,选择第一个数据传输通道,能够更严格保证各无线链路机占用通道发送数据时不会产生干扰,利于实现多级延伸。
