Description
本申请要求在2017年11月18日提交中国专利局、申请号为201711151396.X的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
本公开涉及通信领域,例如,涉及一种时间分配方法、装置及***。
在相关技术中,铜缆接入***包括快速接入用户终端(Fast Access Subscriber Terminal,FAST)***与超高速数字用户线路(Very High Speed Digital Subscriber Line,VDSL)2***。它的网络架构可分为G.FAST/多种类型数字用户线路(x Digital Subscriber Line,xDSL)局端(DPU)与G.FAST/xDSL终端(Customer Premise Equipment,CPE)。其中,G.FAST/xDSL局端(Distribution Point Unit,DPU)可提供多个接口分别与多个终端(CPE)相连,即一个局端模块(Fast Transceiver Unit at the Optical network unit,FTU-O)与一个终端模块(Fast Transceiver Unit at the Remote site,FTU-R)相连(对等式网络(peer-to-peer,P2P)架构),如图1所示,图1是根据相关技术中G.FAST/xDSL***架构示意图。G.FAST/xDSL局端与终端对应接口之间的连接介质可以是双绞线、同轴电缆等铜缆介质。G.FAST采用时分双工(Time Division Duplexing,TDD)工作模式,每个TDD帧包含Mds个下行符号与Mus个上行符号,其中,图1中Tsymb表示符号周期,TF为TDD帧周期,MF=Mds+Mus+1。
动态时间调整(Dynamic Time Assignment,DTA)在正常工作(showtime)阶段对Mds进行动态调整时,通过FTU-O下发DTA更新(DTA update)指令给FTU-R,该指令中包含新TDD帧配置中的下行符号数Mds(新)、以及DTA帧递减计数值(N),如图2所示,图2是根据相关技术中TDD帧结构图。FTU-O重复向FTU-R发送DTA更新指令,其中,每发送一个TDD帧,N就递减1,当N的值递减到0时,就马上触发基于新TDD帧格式进行帧的发送。对于一个协调组或向量(vectoring)组的多线对DTA更新,即协调DTA(Coordinated DTA, cDTA),当多线对之间的DTA更新不同步而导致多根线对不能同时发送上行信号或下行信号,线对之间就会产生严重的近端串扰(NEXT)而且难以消除,从而会大大影响***的性能甚至会导致***崩溃,如图3所示,图3是根据相关技术中cDTA不同步而产生近端串扰的示意图。
针对相关技术中动态时间调整过程中,线对之间产生串扰的问题,目前还没有有效的解决方案。

FTU-R决定何时启动基于新的TDD帧配置信息进行TDD帧的通信以及是否启动采用避免或减少线对之间串扰的特定传输模式的判断依据如下:
(1)当FTU-R在帧递减计数值为零前收到DTA配置消息,并且确认每个FTU-R已经收到DTA配置消息,则在帧递减计数值为零时,启动基于新的TDD帧配置信息进行TDD帧的通信,并且采用正常的传输模式(即在Mus.new(更新的上行符号数)个上行符号内发送数据符号或RMC符号)而不采用用于避免或减少潜在线对之间串扰的特定传输模式。
(2)当FTU-R在帧递减计数值为零前收到DTA配置消息,但其中的Ack(all)=0(即表示头端未确认每个FTU-R已经收到DTA配置消息),则在帧递 减计数值为零时,启动基于新的TDD帧配置信息进行TDD帧的通信,并且采用用于避免或减少潜在线对之间串扰的特定传输模式;只有当确认每个FTU-R已经收到DTA配置消息,则才从用于避免或减少潜在线对之间串扰的特定传输模式转为正常的传输模式。
(3)FTU-R在设定的最小数目周期的TDD帧(或逻辑帧)周期内都未收到DTA配置消息,则采用用于避免或减少潜在线对之间串扰的特定传输模式,即在预先配置或设定的发送符号区域内发送闲置符号(idle symbols),或安静符号(quiet symbols),或停止发送符号。特定传输模式可包括:当(Mus-cDTA_SMax)>Mus.min时FTU-R从Symbol.Mus+cDTA_SMax开始只发送(Mus-cDTA_SMax)个上行quiet symbols,不发送数据符号或RMC符号;当(Mus-cDTA_SMax)<Mus.min时FTU-R从Symbol.Mus+(Mus-Mus.min)开始只发送Mus.min个上行quiet symbols,不发送数据符号或RMC符号。其中,Mus表示原有的上行符号数,cDTA_SMax表示cDTA允许Mds(或Mus)一次调整的最大符号数(步幅)。Symbol.Mus表示原有Mus对应的第一个上行符号位置。Mus.min是指***允许或设定的最小上行符号数。
FTU-O决定何时启动基于新的TDD帧配置信息进行TDD帧的通信以及是否启动采用避免或减少线对之间串扰的特定传输模式的依据如下:
(1)当FTU-O在帧递减计数值为零前已确认每个FTU-R已经收到DTA配置消息,则在帧递减计数值为零时,启动基于新的TDD帧配置信息进行TDD帧的通信,并且采用正常的传输模式而不采用用于避免或减少潜在线对之间串扰的特定传输模式。
(2)当FTU-O在帧递减计数值为零前未确认每个FTU-R已经收到DTA配置消息,则在帧递减计数值为零时,启动基于新的TDD帧配置信息进行TDD帧的通信,或者直接采用正常的传输模式(即在Mds.new(更新的下行符号数)个下行符号内发送数据符号或RMC符号);或者采用用于避免或减少潜在线对之间串扰的特定传输模式,只有当FTU-O确认每个FTU-R都已经收到DTA配置消息,则才从用于避免或减少潜在线对之间串扰的特定传输模式转为正常的传输模式。

1)对于线路1、线路2、线路3的FTU-O,直接启动基于新的TDD帧配置信息Mds.new发送下行符号;
2)对于线路2与线路3的FTU-R,收到了带有Ack(all)=1的DTA配置消息,因此启动基于新的TDD帧配置信息进行TDD帧的通信,并且直接启动基于新的TDD帧配置信息Mus.new发送上行数据符号或RMC符号。
(3)当线路1的FTU-R未收到DTA配置消息(DTAFDC=0,Ack(all)=1),启动基于新的TDD帧配置信息进行TDD帧的通信,即上行符号数为Mus.new,并且采用用于避免或减少潜在线对之间串扰的特定传输模式,即从上行的第一个符号到第(cDTA_SMax-(Mds.new-Mds))个符号发送安静符号(quiet symbols),不发送数据。
(4)当线路1的FTU-R收到带有Ack(all)=1的DTA配置消息后,启动正常的传输模式,即在Mus.new个符号内发送数据符号或RMC符号。
采用上述技术方案,有效提高了cDTA更新的可靠性与健壮性,避免或减少了潜在的线对之间近端串扰与远端串扰,同时,也保证了cDTA更新的高效性,以能尽快地完成TDD帧传输参数的动态调整,有利于线路能基于上下行流量情况快速进行上下行符号数的调整。
