本公开基于申请号为202310340881.0、申请日为2023年3月31日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引用本公开作为参考。
本发明涉及通信技术领域,尤其涉及一种传输方法、装置、计算机可读存储介质和通信设备。
随着概率星座整形等技术的发展,光传送网(OTN,Optical Transport Network)中光层的传输速率可以根据概率分布墒进行调整,即光层可通过概率星座整形实现变速率系统。具体地,进行概率整形的数据的一部分通过分布匹配器整形成麦克斯韦-玻尔兹曼(MB,Maxwell-Boltzmann)分布(类高斯分布),整形后比特流通过前向纠错(FEC,Forward Error Correction)产生校验位,随后将校验位作为符号、整形后的比特流作为振幅,进行结合,生成概率整形后的数据,以此调整光层的传输速率。其中,根据概率星座整形原理,总的数据速率对应于特定的墒及特定的参数λ值(即符号点的分布的参数)。
但光传送网中电层只能进行特定速率的调整,目前光层和电层的速率同步一般是分别指示光层和电层到同样的速率,这个过程中可能会发生数据传输错误。也就是说,目前光层和电层不能统一进行无损的速率调整。

示例性的,所述第一设备在所述第二层,可基于所述第二帧中的空闲时隙、工作时隙、空闲比特、工作比特、空闲块、工作块中的至少一项确定所述第一信息,从而使得所述第一信息可用于指示所述第二帧中的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种,例如指示所述第二帧中的空闲时隙的信息、工作时隙的信息、空闲比特的信息、工作比特的信息、空闲块的信息、工作块的信息、数据速率信息中的至少一项。其中,上述信息例如可以是位置和/或数量,例如空闲时隙、空闲比特、空闲块的位置和/或数量,工作时隙、工作比特、工作块的位置和/或数量等等;或者上述信息还可以是占比,例如空闲时隙、空闲比特、空闲块占全部时隙、全部比特或全部块的比例,工作时隙、工作比特或工作块占全部时隙、全部比特或全部块的比例;或者上述信息还可以是数据速率(或数据率)、

可选的,在调整所述第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率时,保持调整前和调整后所述第一层对应的波特率或符号率不变;或者,保持调整前和调整后所述第一层对应的波特率或符号率不变和/或比特率不变。或者,在通过概率整形处理调整所述第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率时,在调整前和调整后,概率整形处理前的输入比特数(或输入比特率)和概率整形过程增加的冗余比特数(或概率整形过程增加的冗余比特率)之和保持不变。
其中,在本发明各实施例中,载荷又称净荷或payload,也即所述第一帧的载荷还可以称为第一帧的净荷或第一帧的payload。
采用本发明实施例的技术方案,第一设备将第二层的第二帧发送到第一层,所述第二帧中包括用于指示所述第二帧中的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种的第一信息,在第一层,通过所述第一信息确定第一参数,按照所述第一参数调整第一层的第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率,也就是说,本发明实施例通过在第二层的第二帧中携带指示时隙使用信息、比特使用信息、块使用信息和数据速率信息中至少一种的第一信息,第一设备在第一层可根据所述第一信息确定用于调整第一层的第一帧的速率的处理参数,由此可利用第二层的第二帧的比特率或数据率直接指示第一层的第一帧的速率调整过程,即根据第二层的传输数据速率调整第一层的传输数据速率,实现第一层和第二层之间统一的无损速率调整。
作为一种可选的实施方式,所述第一信息包括实时MSI信息和/或实时时隙占有使用信息;所述通过所述第一信息确定第一参数,可以包括:通过所述第二帧对应的实时MSI信息和/或实时时隙占有使用信息确定所述第二帧对应的第一速率信息,基于所述第一速率信息确定所述第一帧对应的第二速率信息,基于所述第二速率信息确定第一参数;或者,通过所述第二帧对应的实时MSI信息和/或实时时隙占有使用信息确定所述第一帧对应的第二速率信息,基于所述第二速率信息确定第一参数。

需要说明的是,基于时隙与数据速率之间的关系,获得所述第二帧中的净荷的时隙使用情况即意味着获得第二帧中的数据速率信息,也就是说,所述实时MSI信息和/或实时时隙占有使用信息除直接指示第二帧中的净荷的时隙使用情况之外,还可间接指示第二帧的数据速率信息,也即所述实时MSI信息和/或实时时隙占有使用信息可用于指示所述第二帧中的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种。
可选的,所述第二帧的开销部分携带有所述实时MSI信息和/或所述实时时隙占有使用信息,即可在第二帧的开销中插入实时MSI信息和/或实时时隙占有使用信息,以指示第二帧的净荷的时隙使用情况。

基于前述实施例,本发明实施例还提供一种传输方法。本实施例针对将第二层的第二帧发送到第一层的过程进行说明,可选的,所述第二层包括第一容器、第二容器和第三容器;所述方法还可以包括:将业务映射到所述第一容器,将所述第一容器映射到所述第二容器,以及将所述第二容器映射到所述第三容器;或者,所述第二层包括第一容器和第三容器;所述方法还包括:将业务映射到所述第一容器,以及将所述第一容器映射到所述第三容器。

下面结合具体的示例对本发明实施例的传输方法进行详细说明。在以下示例中,均以第一设备为发射端设备、第二设备为接收端设备为例进行说明。
图7a为本发明实施例的传输方法的交互流程示意图,图7b为本发明实施例的传输方法中第一层的时隙或比特或块的变化示意图,图7c为本发明实施例的传输方法中第一层的处理流程示意图;结合图7a、图7b和图7c所示,对于一般的光传送网络设备,如果存在上层(或第二层,例如,电层、数字层、MAC层、逻辑层等)和下层(或第一层,例如光层、物理层等)的划分,均可采用本示例的传输机制。
其中,在本示例的传输过程中还可存在速率调整,图8为本发明实施例的传输方法中进行速率调整后的光信道容量变化示意图,结合图7b和图8所示,本示例中的速率调整具体可通过增加或减少空闲比特(无效比特、空闲时隙、空闲块等)来保持上层(或第二层)和下层(或第一层)之间的接口的符号率(波特率)不变;同时,在速率调整时,下层(或第一层)的净荷或载荷的比特率与上层(或第二层)去除空闲比特(无效比特、空闲时隙、空闲块等)后的比特率,在速率调整前后都保持一致;此外,发射端(或第一设备)和接收端(或第二设备)的比特率也可保持一致。
本示例中,光层相当于前述实施例中的第一层;第一容器、第二容器和第三容器组成处理层相当于前述实施例中的第二层,或者第一容器和第三容器组成处理层相当于前述实施例中的第二层。
具体地,所述传输方法可包括:
在发射端,第一设备(例如发射设备)接收业务,将业务映射到第一容器(或低阶容器,例如ODUflex),再将第一容器映射到第二容器(高阶容器,例如ODUk)中;或者,业务仅映射到第一容器(例如ODUflex)中。
需要说明的是,本示例在映射到第一容器或第二容器的过程中,还可进行速率调整,如图7a中左侧的时隙示意所示,速率调整前,映射到第一容器的工作时隙数量或工作比特数或工作块数为2个;在速率调整时,第一容器的工作时隙数或工作比特数或工作块数发生变化,例如增加了一个工作时隙或工作比特数或工作块数。
将第一容器(例如ODUflex)或第二容器(例如ODUk)映射到第三容器(或电层容器,例如OTUC)中,形成电层帧或第二帧,例如可增加电层开销(OH),形成电层帧或第二帧。其中,所述第三容器(或电层帧、第二帧)的帧开销中包括第一信息,可参照图2和图3a
所示,所述第一信息用于指示第二帧(或第三容器)中的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种。示例性的,所述第一信息例如可以包括实时MSI信息和/或实时时隙占有使用信息,或者,所述第一信息还可以包括第二帧(或第三容器)对应的第一速率信息。
上述过程相当于前述实施例中第一设备的第二层的处理过程。
在第三容器,生成第二层和第一层间的接口信号,通过第二层和第一层之间的接口(例如FlexO)发送第三容器到第一层,例如图2所示将OTUC帧封装到FlexO帧的净荷或载荷中,并增加开销,基于FlexO帧将第二层的第二帧(或第三容器)发送至第一层。
在第一层,根据第一信息去除第二帧中的空闲时隙或空闲比特或空闲块后,封装得到第一帧。
这时,还可根据所述第一信息确定第一帧对应的第二速率信息,在第一帧的开销中加入所述第二速率信息。
示例性的,第一层的处理过程具体可参照图7b所示,第三容器(或电层帧、第二帧)通过接口到达第一层,可根据第三容器(或电层帧、第二帧)中包括的实时MSI信息和/或实时时隙占有使用信息去除第三容器或第二帧中的空闲时隙或空闲比特或空闲块,形成下层容器或光层的载荷或净荷(payload),增加下层开销(overhead),所述下层开销中包括所述光层的载荷或净荷的比特率(即第二速率信息),形成下层帧(相当于前述实施例中的第一帧)。例如,请参照图2b,在第一层(例如第一设备中的光模块和/或光DSP芯片中),从FlexO帧中解出OTUC帧,根据OTUC帧的开销中的实时MSI信息和/或实时时隙占有使用信息,删除OTUC帧中没有使用的时隙(空闲时隙),并根据实时MSI信息和/或实时时隙占有使用信息产生DSP帧(即第一帧、光层帧)中传输数据信息的实时速率信息(即第二速率信息),或者根据OTUC帧的开销中还包含的所述OTUC帧的净荷的实时速率信息(即第一速率信息)确定DSP帧中传输数据信息的实时速率信息(即第二速率信息),将所述第二速率信息插入到DSP帧中。
基于所述第二速率信息确定第一参数,按照所述第一参数对第一层的第一帧进行处理,所述处理用于调整所述第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率,其中,所述第一参数例如可以是第一调制格式信息、第一概率整形参数、第一概率整形自由度、第一概率整形整形度、第一概率整形冗余度、第一概率整形输入比特数或比特率等等;对处理后的第一帧进行前向纠错(FEC)获得校验位,在第一帧中加入校验位;以及在处理后的第一帧中加入帧同步信息,所述帧同步信息包括帧头同步定位信息、向导比特、训练序列等等。
相关技术中,光层的传输速率可以根据概率分布墒进行调整,而电层则只能进行特定速
率的调整,如图8中左部分所示,即光层和电层不能统一地进行无损的速率调整。本示例可根据用于指示电层帧(即第二帧)的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种的第一信息,确定光层帧(即第一帧)对应的第二速率信息,基于所述第二速率信息确定对第一层的第一帧进行处理的第一参数,由此实现光层和电层统一的无损速率调整,如图8中右部分所示。
示例性的,如图7c所示,基于DSP帧中数据的实时速率信息(即第二速率信息),确定比特的调制方式和/或调制参数,例如概率星座整形或者混合调制格式,和/或概率星座整形参数(例如概率整形自由度、概率整形冗余度、概率整形输入比特数或比特率等等);按照确定的调制方式和/或调制参数对DSP帧中的数据进行处理,并对DSP帧中处理后的数据以及DSP帧中数据的实时速率信息进行FEC纠错,并产生校验位(parity);在DSP帧中插入调制整后的数据、DSP帧中数据的实时速率信息、帧头同步定位信息、向导比特(pilot)、训练序列(training sequence)、校验位等。
如图7b所示,下层容器或光层的载荷或净荷比特率(即传输数据信息的比特率)与第三容器(或电层帧、第二帧)中工作时隙的比特率同步。例如,通过概率整形保持概率整形输出的波特率不变,同时使概率整形前的输入比特数与第三容器(或上层帧、第二帧)中工作时隙的比特数同步,即概率整形后,传输的除去光层开销外的净荷或载荷的比特率与第三容器(或上层帧、第二帧)中工作时隙的比特率(即去除空闲时隙或空闲比特或空闲块后的比特率)同步。也就是说,本示例可通过第一参数与第一信息关联,调整光层或第一层的调制格式和/或概率整形参数(例如概率整形自由度、概率整形冗余度、概率整形输入比特数或比特率等等),即调整光层的净荷或载荷的比特率,从而可实现光层(或第一层)和电层(或第二层)的速率同步,即电层(或第二层)去除空闲时隙、空闲比特或空闲块后的比特率与光层的净荷或载荷的比特率保持一致。
上述过程相当于前述实施例中第一设备的第一层的处理过程。
进一步地,如图7c所示,在发射端,还进行第一帧(例如DSP帧)从比特到符号的映射(mapping),第一设备将映射后的第一帧发送给第二设备(即接收设备)。
在接收端,第二设备从第一设备接收光层帧,对光层帧进行相当于上述第一设备的处理过程的逆过程。所述光层帧相当于前述实施例中第一设备发送给第二设备的第一帧,所述光层帧(或第一帧)中至少包括第二速率信息,所述第二速率信息可用于指示第二参数,根据所述第二参数在第一层调整所述第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率时,所述处理用于调整所述第一帧的载荷的比特率或所述第一帧中传输数据信息的比特率,所述第二设备根据调整后的第一帧可获得第二帧,该第二帧中包括用于指示第二帧中的
时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种的第一信息,由此,本示例通过在第一帧中携带第二速率信息,使得接收端可根据第一帧中携带的所述第二速率信息确定发射端处理过程对应的逆处理过程参数(即第二参数),实现数据在第一设备和第二设备之间的无损传输,同时,由于设备第一层和第二层中通过第二帧中携带可用于指示第一速率信息的第一信息,使得可根据第二帧中携带的所述第一信息确定第一层的第二速率信息所关联的、发射端处理过程参数(即第一参数),实现第一层和第二层之间的无损速率调整。
接收端的传输方法具体可包括:
在第一层,获得第一帧中的第二信息,所述第二信息至少包括第二速率信息;确定所述第二速率信息对应的第二参数,根据所述第二参数对所述第一帧进行解调制或解码处理;根据调整后的第一帧恢复得到不包含空闲时隙或空闲比特或空闲块的第二帧,所述不包含空闲时隙或空闲比特或空闲块的第二帧中包括所述第一信息;根据所述第一信息,在所述不包含空闲时隙或空闲比特或空闲块的第二帧中添加空闲时隙或空闲比特或空闲块,形成第二帧,其中,所述第一信息用于指示所述第二帧中的时隙使用信息、比特使用信息、块使用信息和数据速率信息中的至少一种。
示例性的,第二设备接收光层帧,利用帧头同步定位信息、向导比特、训练序列等,通过DSP算法解出符号,并将符号解映射为比特,从比特中读出校验位,进行前向纠错解码,获得所述光层帧中包含数据的实时速率信息(即第二速率信息),根据所述第二速率信息确定解调制方式,例如概率星座整形的映射解码或者混合调制的映射解码等,得到原始数据比特,即光层帧(或第一帧)的净荷,进一步恢复出包含工作时隙的第三容器或电层帧或第二帧(即不包含空闲时隙或空闲比特或空闲块的第三容器或上层帧或第二帧),再根据所述第二帧的开销中包括的第一信息,例如实时MSI信息和/或实时时隙占有使用信息,在该第三容器或电层帧或第二帧中添加空闲时隙或空闲比特或空闲块,得到第三容器或电层帧或第二帧,例如OTUC帧。
生成光层和电层的接口信号,通过电层和光层之间的接口发送第三容器,将第三容器解映射得到第二容器,以及将所述第二容器解映射得到第一容器,将所述第一容器解映射为业务;或者,将第三容器解映射得到第一容器,将所述第一容器解映射为业务。
示例性的,可根据第一层恢复得到的OTUC帧组成FlexO帧,基于所述FlexO帧从第一层发送至第二层,在第二层中从FlexO帧中解出OTUC帧,在从OTUC帧中解出ODUk或ODUflex,最后从ODUk或ODUflex中解出业务。
