Description

一种管理消息的传输方法及相关装置
本申请要求于2018年04月28日提交中国专利局、申请号为201810402069.5、发明名称为“一种数据传输方法及相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种管理消息的传输方法及相关装置。
背景技术
在电缆调制解调终端系统(cable modem termination system,CMTS)中,接入平台管理设备例如融合有线接入平台中心(converged cable access platform core,CCAP-Core),负责除物理层(physical,PHY)之外的全部功能,包括终端业务管理和介质访问控制(media access control,MAC)层管理。数据转换设备是上述CMTS中的常见设备,例如远程物理设备(remote physical device,RPD),用于按照协议将数据帧进行解析,转化成模拟调制信号,通过射频(radio frequency,RF)线路传输给电缆调制解调终端(cable modem,CM)。
上述RPD不具备处理控制帧如MAC帧的能力,MAC帧由上述CCAP-Core通过在多条下行信道进行广播,以发送至CM。
在上述MAC帧广播方式中,由于下行信道的信道带宽有限,将MAC帧在多条下行信道中进行广播,将会占用部分下行带宽,增加了下行带宽的开销,同时降低了下行数据传输速率。
发明内容
有鉴于此,本申请实施例第一方面提供了一种管理消息的传输方法,包括:第一设备接收第二设备发送的主信道配置消息,该主信道配置消息用于为该第一设备配置至少两个主信道;该第一设备根据该主信道配置消息确定该至少两个主信道,该至少两个主信道对应的介质访问控制MAC管理消息的相似度超过预设阈值,一个主信道对应一个MAC管理消息;该第一设备接收该第二设备发送的目标MAC管理消息,该目标MAC消息为该至少两个主信道中任一个信道对应的MAC管理消息,该MAC管理消息用于控制对应主信道上的数据传输;该第一设备复制该目标MAC管理消息至所述至少两个主信道中的每一个信道上进行发送。
从以上技术方案可以看出,本申请实施例具有以下优点:对于相似度超过预设阈值的MAC管理消息,第二设备只将其中一个MAC管理消息作为目标MAC管理消息发送至第一设备,进而由第一设备将该目标MAC管理消息复制到所有的主信道上,从而,第二设备在发送至少两个主信道上对应的相似度超过预设阈值的MAC管理消息时,无需在至少两个主信道上分别进行发送,可以有效地减少MAC管理消息的信息量,节省下行数据带宽的开销,提高下行数据传输速率。
在第一方面的一种实现方式中,该主信道配置消息中包括主信道标识,该第一设备根 据该主信道配置消息确定该至少两个主信道,包括:该第一设备从该主信道配置消息中获取该主信道标识;该第一设备根据该主信道标识确定该至少两个主信道。通过主信道标识可以准确辨别出主信道,以保证准确标识主信道,从而使得目标MAC管理消息可以复制到准确的主信道上,避免传输错误。
在第一方面的一种实现方式中,该第一设备接收该第二设备发送的目标MAC管理消息,包括:该第一设备通过广播信道接收该第二设备发送的该目标MAC管理消息。通过广播信道对目标MAC管理消息进行广播,可以不占用其他下行数据带宽,从而有效降低下行数据带宽的开销,提高下行数据传输速率。
在第一方面的一种实现方式中,在该第一设备复制该目标MAC管理消息至该至少两个主信道中的每一个信道上进行发送之前,该方法还包括:该第一设备接收该第二设备发送的指示信息,该指示信息用于指示该目标MAC管理消息的相似度超过该预设阈值。
在第一方面的一种实现方式中,该MAC管理消息包括:MAP格式的上行带宽分配消息。一方面,上行带宽分配消息的信息量较大,通过第一方面提供的管理消息传输方法可以有效地降低下行数据带宽的开销,提高下行数据传输速率。另一方面,MAP格式的行带宽分配消息没有关联的下行信道,MAP格式的下行带宽分配消息内容几乎是完全相同的,相似度可达到百分之百。
本申请实施例第二方面提供了一种管理消息的传输方法,包括:若介质访问控制MAC管理消息中存在相似度超过预设阈值的至少两个MAC管理消息,第二设备根据该至少两个MAC管理消息生成主信道配置消息;该第二设备向第一设备发送主信道配置信息,该主信道配置消息用于为该第一设备配置至少两个主信道,该至少两个主信道与该至少两个MAC管理消息一一对应;该第二设备向该第一设备发送目标MAC管理消息,该目标MAC消息为该至少两个主信道中任一个信道对应的MAC管理消息。
在第二方面的一种实现方式中,该主信道配置消息中包括主信道标识;该第二设备根据该至少两个MAC管理消息生成主信道配置消息,包括:该第二设备对该至少两个MAC管理消息对应的信道进行标记,得到该主信道标识;该第二设备根据该主信道标识生成该主信道配置消息。
在第二方面的一种实现方式中,该第二设备向该第一设备发送目标MAC管理消息,包括:该第二设备将该至少两个主信道中任一个信道对应的MAC管理消息确定为该目标MAC管理消息;该第二设备通过广播信道向该第一设备发送该目标MAC管理消息。

具体实施方式
本申请实施例提供了一种管理消息的传输方法,用于节省下行带宽开销,提高下行数据传输速率。
下面将结合本申请中的附图,对本申请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申请一部分实施例,而不是全部的实施例。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例使用于CMTS系统中,尤其是按照remote-PHY标准进行组网的通信系统中。图1为本申请实施例提供的一种CMTS系统架构图,如图1所示为remote-PHY系统中包括:CCAP-Core、RPD以及CM或者机顶盒(set top box,STB),其中,CCAP-Core和RPD 通过融合互联网络(converged interconnect network,CIN)连接,该CIN可以是使用无源光纤网络(passive optical network,PON)组网得到,也可以是由以太网external组网得到。CCAP-Core用于控制数据转发器和集线器之间的集线器接入网络传输,以及控制集线器与光纤节点之间的光纤接入网络传输。RPD用于控制光纤接入网络中的数据帧的解析,转化为模拟调制信号之后,通过RF线路传输至CM或者STB。Coax是一种接口技术,Coax接入网络便是使用Coax接口技术得到的一种接入网络。该Coax接入网络可以作为RPD对应的RF线路,进行信号传输。CM或者STB用于控制客户终端设备(customer premise equipment,CPE),例如网络电视机等。在上述remote-PHY系统架构中采用上行以太物理层接口(upstream external PHY interface,UEPI)协议进行上行数据传输,采用下行以太物理层接口(downstream external PHY interface,DEPI)协议进行下行数据传输。CCAP-Core和RPD之间的控制面消息采用通用控制面(generic control plane,GCP)协议进行传输。
图1中示出的CIN网络是由PON进行组网得到的,如上述CIN网络的组网方式,上述图1中的CIN网络还可以由以太网external组网得到,具体组网方式与上述PON组网方式类似,此处不做过多赘述。
当采用以太网组网接入时,CCAP-Core和RPD之间采用点到点的传输方式。图2为本申请实施例提供的一种以太网组网示意图,如图2所示,CCAP-Core中存在4个MAC域domain,一个MAC域对应一个PHY。当采用PON网络组网接入时,CCAP-Core和RPD之间一般会采用点到多点的传输方式。图3为本申请实施例提供的一种PON组网示意图,如图3所示,CCAP-Core中存在多个MAC域domain,一个MAC域对应两个PHY。
本申请实施例提供的管理消息的传输方法,与现有MAC管理消息的传输方法相比,主要区别在于:本申请实施例利用下行信道对应的MAC管理消息之间的高度相似性,对于高度相似的MAC管理消息,在发送过程中只发送其中一个MAC管理消息至第一设备如RPD,进而,由没有管理消息处理能力的第一设备将MAC管理消息复制到对应的多个主信道上,转发至第三设备。
为了便于理解本申请实施例提供的管理消息的传输方法,下面结合具体的实施例对本申请实施例中的传输方法进行详细说明,其中,第一设备以上述RPD为例,第二设备以上述CCAP-CORE为例。
图4为本申请实施例提供的一个传输方法的实施例示意图。
如图4所示,本申请实施例提供的管理消息的传输方法包括:
401、若存在相似度超过预设阈值的至少两个MAC管理消息,CCAP-Core根据该至少两个MAC管理消息生成主信道配置消息。
在一种示例中,主信道配置消息中包括主信道标识。若CCAP-Core检测到在下行信道对应的MAC管理消息中,存在两个以上MAC管理消息的相似度超过预设阈值,CCAP-Core对上述两个以上MAC管理消息对应的下行信道标记为主信道,并保存相应的主信道标识。进一步,CCAP-Core依据该主信道标识生成主信道配置信息。
需要说明的是,上述主信道配置信息中除主信道标识之外,还可以携带其他控制信息, 换言之,出于节省下行信道资源的目的,将主信道标识携带于其他控制信息得到信息均为本申请中主配置信息的范畴,至于其他控制信息此处不再一一列举。
还需要说明的是,本实施例中,可以对GCP协议进行扩展,增加信道标识bit位,以标识主信道和普通下行信道。具体的,下行信道可以是下行单载波正交幅度调制(single-carrier quadrature amplitude modulation,SC-QAM)信道和下行正交频分调制(orthogonal frequency division multiplexing,OFDM)信道,分别在下行SC-QAM信道和下行OFDM信道中增加主信道标识,以示区别主信道和普通下行信道。
402、CCAP-Core向RPD发送主信道配置信息。
主信道配置消息为用于为RPD配置主信道,并且,该主信道的数量为至少两个。该至少两个主信道中,一个主信道对应一个MAC管理消息,这些主信道中传输的MAC管理消息之间的相似度超过预设阈值,例如,预设阈值可以为0.5、0.8和0.9等。
在一种示例中,MAC管理消息包括上行信道分配消息,其格式为MAP格式。MAP格式的上行信道分配消息没有关联的下行信道,每个下行信道中对应的上行信道分配消息是完全一样的,其相似度达到百分之百。在发送过程中,RPD无需具有MAC层的处理能力,只要在各下行信道上复制上行信道分配消息即可。
图5(a)为本申请实施例提供的一种MAP消息格式;图5(b)为本申请实施例提供的另一中MAP消息格式;图5(c)为本申请实施例提供的又一种MAP消息格式。图5(a)、图5(b)和图5(c)中示出了三种没有关联下行信道的MAP消息格式,三种消息格式均为8个字节。图5(a)中示出了一种普通MAP消息格式,其中,信息元素数量占8个bit(16-23bit),预留位有8个bit(24-31bit)。图5(b)中示出了一种非探针MAP消息格式,与图5(a)中的MAP消息格式的区别在于:图5(b)中的信息元素数量占9个bit(16-24bit),预留位占3个bit(25-27bit),新增加了ACT位,其占4个bit(28-31bit)。图5(c)中示出了一种探针MAP消息格式,与图5(b)中的MAP消息格式的区别在于:图5(c)中的消息元素为探针消息元素,并且没有确认时间、修正补偿以及数据补偿。上述图5(a)、图5(b)和图5(c)中所示的MAC管理消息头和MAP消息元素一般各占2个字节,探针消息元素一般为4个字节,但也可根据实际情况调整其各自的字节数量大小。
403、RPD根据主信道配置消息确定至少两个主信道。
RPD接收到CCAP-Core发送的主信道配置消息。RPD对主信道配置消息进行解析,从下行信道中确定至少两个主信道。
在一种示例中,RPD通过主信道配置消息中携带的主信道标识,确定下行信道中主信道标识有效的信道为主信道。
404、CCAP-Core向RPD发送目标MAC管理消息。
该目标MAC管理消息为相似度超过预定阈值的各个MAC管理消息中的任意一个。CCAP-CORE通过下行信道将该目标MAC管理消息发送至RPD。
在一种示例中,CCAP-Core将目标MAC管理消息标记为广播消息,从而,使用广播信道将该目标MAC管理消息发送至RPD。
需要说明的是,除广播信道传输目标MAC管理消息之外,CCAP-Core还可以使用其他 下行信道传输目标MAC管理消息。
405、CCAP-Core向RPD发送指示信息。
指示信息可以用于指示目标MAC管理消息的相似度超过预设阈值,以间接指示RPD复制目标MAC管理消息至上述每一个主信道上。或者,指示消息也可以直接指示RPD将目标MAC管理消息复制到上述每一个主信道上。
CCAP-Core可以将该指示消息在目标管理消息发送之前或者之后单独发送至RPD,或者,CCAP-Core也可以将目标管理消息和指示消息一起发送至RPD。
406、RPD复制目标MAC管理消息到至少两个主信道上,将该目标MAC管理消息转发至第三设备。
在一种示例中,RPD从广播信道中接收到的目标MAC管理消息,进而,RPD将该目标MAC管理消息复制到各个主信道上,并通过主信道将目标MAC管理消息转发至第三方设备,例如CM或者STB。可选的,该目标MAC管理消息可以为MAP格式的上行带宽分配消息。
本实施例中,对于相似度超过预设阈值的MAC管理消息,CCAP-Core只将其中一个MAC管理消息作为目标MAC管理消息发送至RPD,进而由RPD将该目标MAC管理消息复制到所有的主信道上进行转发,从而,CCAP-Core在发送至少两个主信道上对应的相似度超过预设阈值的MAC管理消息时,无需在至少两个主信道上分别进行发送,可以有效地减少MAC管理消息的信息量,节省了下行数据带宽的开销,提高了下行数据传输速率。
需要说明的是,本实施例中管理消息的传输方法可以用于上述图2和图3所示的两种组网方式中。此外,本申请实施例中提供的方法适用但不局限于remote-PHY系统架构下的CMTS系统中,也可以用于其他类似的通信场景下。
结合图1中的架构图,对本申请实施例中管理消息的传输方法的应用于remote-PHY系统架构下的CMTS系统中的应用场景进行说明。
如图6所示,本申请实施例提供的一个应用场景示意图,包括:
601、CCAP-Core向RPD发送主信道配置信息。
该主信道配置信息中携带有N个主信道标识,以将N个下行信道标记为主信道。
602、CCAP-Core通过广播信道向RPD发送MAP消息。
该MAP消息是上述图5(a)、图5(b)和图5(c)中所示的任意一种格式的MAP消息。
603、RPD在N个主信道中发送MAP消息至CM。
RPD广播信道接收到的MAP消息赋值到主信道配置信息指示的N个主信道上,并发送至CM,其中N为大于等于2的整数。
需要说明的是,图6对应的应用场景中所涉及的具体技术特征在,例如但不限于,图4中的管理消息的传输方法中已经有详细的描述,在此不再赘述。
