Description

一种传输数据的装置、系统和方法 技术领域
本发明涉及通信技术领域,特别涉及一种传输数据的装置、系统和方法。
背景技术
长期演进网络(Long Term Evolved,简称“LTE”)是第三代合作伙伴计划(3rd Generation Partnership Program,简称“3GPP”)组织中各厂商积极研究的一种移动通信网络,是通用移动通信系统(Universal Mobile Telecommunication System,简称“UMTS”)的演进网络。LTE的目的是提供一种能够降低时延,提高用户数据速率,增加系统容量和覆盖的低成本网络。但是,随着智能手机的大规模增长,蜂窝网流量压力激增,目前运营的网络已经感受巨大的压力,即使LTE大规模部署也只能满足部分需求。
现有技术中,为了应对移动数据业务流量的剧增,网络运营商提出了在设备(User Equipment,简称“UE”)和演进基站(evolved Node Base,简称“eNB”)之间部署小小区small cell,small cell采用低功率节点(Low Power Node,简称“LPN”)部署,在LPN的覆盖范围内,用户可以享用LPN为其提供业务传输。LPN可以是微微蜂窝(Pico-cell,简称“Pico”)、家庭基站(Femto-cell,简称“Femto”)、中继站(Relay station,简称“Relay”)等等。其中,LPN与UE之间的链路称为接入链路,LPN与基站之间的链路称为回程链路。当LPN密集化部署时,其覆盖半径变小,覆盖下的用户数较少。由于UE的移动性以及其使用业务种类变化的随机性,使LPN的业务波动性变化比较明显,这就造成了网络对于LPN回程链路容量(包括了上行容量和下行容量)的需求也存在明显的波动。
在实现本发明的过程中,发明人发现现有技术至少存在以下问题:
一般来说,考虑到网络的部署成本,LPN回程链路的容量会基本满足需求,由于基站到LPN的回程链路上的存在上下行业务的不均衡性,通常情况是下行业务量远远超过上行业务量,所以,当LPN覆盖下的用户使用大流量业务时, 即下行业务量很大或上行业务量很大,可能会超出回程链路上的网络容量,造成回程链路上的网络容量无法保证。
发明内容
为了解决现有技术中下行业务量很大或上行业务量很大,可能会超出回程链路的容量,造成LPN回程容量受限的问题,本发明实施例提供了一种传输数据的装置、系统和方法,在基站和LPN之间加入第一网络节点,且第一网络节点与基站之间建立第一回程链路,第一网络节点与LPN之间建立第二回程链路,当基站与LPN之间下行业务量很大或者上行业务量很大时,可以通过第一回程链路和第二回程链路传输LPN与基站之间的用户面数据,从而保证了基站和LPN之间回程链路上的网络容量,技术方案如下:

在该另一种实现方式中,可选地,第一承载分流请求消息还可以包括主回程链路的负载信息,其中主回程链路为基站与LPN之间的直接链路;
则第一网络节点根据第一承载分流请求消息,确定第二待承载业务组的信息,可以包括:
第一网络节点根据主回程链路的负载是否超过预设门限,确定第二待承载业务组是否包括待承载业务。当第一网络节点判断出主回程链路的负载超过预设门限时,从第一待承载业务组中选择第二待承载业务组包括的待承载业务;否则,不从第一待承载业务组中选择第二待承载业务组包括的待承载业务。
当第二待承载业务组包括待承载业务时,第一承载分流确认消息还可以包括待承载业务的第一网络节点侧链路配置信息。基站根据第一网络节点侧链路配置信息配置第一回程链路的下行链路。
此时,该方法还可以包括:

具体地,在本发明实施例中,待承载业务的基站侧链路配置信息可以包括待承载业务的上行隧道标识信息(例如,上行隧道的隧道协议-终端编号(GPRS  Tunneling Protocol Tunneling End ID,简称“GTP-TEID”))和传输网络层地址(Transport Network Layer address,简称“TNL address”)信息。待承载业务的第一网络节点侧链路配置信息可以包括下行隧道标识信息(例如下行隧道的GTP-TEID)和TNL address信息。
在该另一种实现方式中,第一网络节点与LPN建立第二回程链路可以包括:
第一网络节点确定第三待承载业务组的信息,其中第三待承载业务组包括第二承载业务组中LPN能够承载的业务。

其中,第一网络节点通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,包括:
当第二回程链路为LPN的小区内的上行链路时,第一网络节点通过LPN的小区内的上行链路,向LPN传输基站通过第一回程链路分流的用户面数据;
或者,当第二回程链路为LPN的小区内的下行链路时,第一网络节点通过LPN的小区内的下行链路,接收LPN向基站发送的用户面数据,并将LPN向基站发送的用户面数据通过第一回程链路传输给基站。
采用LPN的小区内的上行链路传输下行数据(即基站通过第一回程链路分流的用户面数据),根据业务传输的不均衡性,当上行链路上的业务量不多时, 利用该上行链路中的空闲资源传输下行数据,可以有效地降低下行业务量,有利于保证整个链路的容量。同样地,采用LPN的小区内的下行链路传输上行数据(即LPN向基站发送的用户面数据),当上行数据量很大,并且下行链路上的业务量不多时,在下行链路的空闲资源上传输上行数据,可以有效地降低上行业务量,有利于保证整个链路的容量。

步骤401:LPN与第一网络节点建立第二回程链路。
步骤402:LPN通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,第一回程链路为基站与第一网络节点之间建立的链路。
具体地,第一回程链路通过前述实施例五和实施例六中的方法建立,这里不再赘述。
实现时,LPN与第一网络节点建立第二回程链路,存在以下三种实现形式:
第一种实现形式:LPN接收第一网络节点发送的第二承载分流请求消息,第二承载分流请求消息包括第二待承载业务组的信息,第二待承载业务组包括第一待承载业务组中第一网络节点能够承载的业务,第一待承载业务组的信息包括基站请求分流的至少一项待承载业务的信息;

第三种实现形式:LPN接收基站发送的第二承载分流请求消息,第二承载分流请求消息包括第二待承载业务组的信息,第二待承载业务组包括第一待承载业务组中第一网络节点能够承载的业务,第一待承载业务组的信息包括基站请求分流的至少一项待承载业务的信息;
LPN根据第二承载分流请求消息,确定第三待承载业务组的信息,其中第三待承载业务组包括第二承载业务组中LPN能够承载的业务;
LPN向基站发送第二承载分流确认消息,第二承载分流确认消息包括第三待承载业务组的信息。
进一步地,当LPN接收基站发送的第二承载分流请求消息,第二承载分流请求消息还可以包括第一网络节点的身份信息。第一网络节点的身份信息可以通过第一网络节点的上下文获取,其可以是小区无线网络临时标识(Cell Radio Network Temporary Identifier,简称“C-RNTI”)。
实现时,LPN通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,可以包括:
当第二回程链路为LPN的小区内的上行链路时,LPN通过LPN的小区内的上行链路,向第一网络节点发送用户面数据,使得第一网络节点将LPN发送的用户面数据发送给基站;
当第二回程链路为LPN的小区内的下行链路时,LPN通过LPN的小区内的下行链路,接收第一网络节点发送的基站通过第一回程链路分流的用户面数据。
本发明实施例通过在基站和LPN之间加入第一网络节点,LPN与第一网络节点建立第二回程链路,并且LPN可以通过第二回程链路与第一网络节点传输基站通过第一回程链路分流的用户面数据,当基站与LPN之间下行业务量很大上行业务量很大时,LPN通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,从而保证了基站和LPN之间回程链路上的 网络容量。
实施例八
本实施例提供一种传输数据的方法,在本实施例中,基站与LPN之间不存在主回程链路,并且第一网络节点直接从LPN接收LPN能够承载的业务的信息,其中主回程链路为基站与LPN之间的直接链路,如图9所示,该方法包括:
步骤501:基站向第一网络节点发送第一承载分流请求消息。
其中,第一承载分流请求消息用于指示第一网络节点完成第一网络节点侧的承载配置。第一承载分流请求消息还用于通知第一网络节点基站需要建立一条与LPN之间的回程链路。第一承载分流请求消息可以包括LPN的身份识别信息和第一待承载业务组的信息,第一待承载业务组的信息包括基站请求分流的至少一项待承载业务的信息。一项待承载业务可以只包括上行业务,也可以只包括下行业务,还可以同时包括上行业务和下行业务。
具体地,对于E-RAB来说,第一待承载业务组即是第一待承载E-RAB列表,第一待承载E-RAB列表包括至少一个表项,每个第一待承载E-RAB列表的表项包括一个E-RAB的信息。一项待承载业务的信息对应为一个第一待承载E-RAB列表的表项中的一个E-RAB的信息。第一待承载E-RAB列表中的每个表项中的E-RAB的信息都携带了E-RAB的身份(ID-entification,简称“ID”)信息和服务质量(Quality of Service,简称“QoS”)需求信息。具体地,第一待承载E-RAB列表中的表项的个数可以用来表示基站请求分流的E-RAB的数目。对应地,待承载E-RAB可以只包括上行E-RAB,也可以只包括下行E-RAB,还可以同时包括上行E-RAB和下行E-RAB。
实现时,第一承载分流请求消息还可以包括待承载E-RAB的基站侧链路配置信息,其中,待承载E-RAB的基站侧配置链路信息包括上行隧道标识信息(例如,上行GTP-TEID)和TNL address信息。第一网络节点可以根据上行隧道标识信息和第一承载分流请求消息中的TNL address信息建立第一回程链路的上行链路,第一回程链路的上行链路为第一网络节点到基站的单侧链路。其中,上行隧道标识信息是基站为第一网络节点分配的基站侧的GTP-TEID,相应地,下行隧道标识信息是第一网络节点为基站分配的第一网络节点侧的GTP-TEID。
LPN的身份识别信息是基站或者第一网络节点上设置的第一网络节点和基 站第一回程链路上识别LPN的标识信息,其获得方式有多种,例如,第一网络节点最初通过扫描周围第一网络节点系统信息的方式发现了LPN,然后给该LPN分配了一个网络接口标识,并将该网络接口标识通知给基站。实现时,第一网络节点和基站可以分别采用不同的网络接口标识表示同一个LPN,也可以采用相同的网络接口标识表示同一个LPN。在本实施例中,第一网络节点和基站侧采用了相同的网络接口标识表示同一个LPN。
需要说明的是,在步骤501之前基站可以已经进行了基站侧的与第一回程链路相关的网络接口的配置。基站侧与第一回程链路相关的网络接口的配置为现有技术,这里不再赘述。
步骤502:第一网络节点接收第一承载分流请求消息,并向LPN发送第二承载分流请求消息。
其中,第二承载分流请求消息包括第二待承载业务组的信息,第二待承载业务组包括第一待承载业务组中第一网络节点能够承载的业务。
在第一网络节点向LPN发送第二承载分流请求消息之前,该方法还可以包括:
第一网节点从第一待承载业务组中筛选出,第一网节点能够承载的业务,得到第二待承载业务组的信息。对于E-RAB来说,即第一网节点从第一待承载E-RAB列表中筛选出,第一网节点能够承载的E-RAB对应的表项,得到第二待承载E-RAB列表。
其中,第二待承载E-RAB列表是第一网络节点根据自己传输能力、各个E-RAB的QoS要求以及当前的网络状况等条件判断出的可以同时建立的E-RAB。举例来说,基站要求建立#1、#2、#3三项E-RAB(即第一待承载E-RAB列表中有三项E-RAB),但是第一网络节点根据自己传输能力、三项E-RAB的QoS要求以及当前的网络状况等条件判断出无法支持三项E-RAB同时建立,而只能建立#1和#2两条E-RAB,所以#1和#2便是被第一网络节点允许接入的E-RAB。
需要说明的是,传输给LPN的第二待承载E-RAB列表至少包括一个表项,其每个表项中的E-RAB的信息包括QoS信息。
实现时,第二承载分流请求消息用于请求LPN根据第二待承载E-RAB列表,确定待承载E-RAB在与第二回程链路相关的网络接口上的数据无线承载(Data  Radio Bearer,简称“DRB”)配置,得到LPN侧与第二回程链路相关的网络接口的DRB配置信息。
步骤503:LPN接收第二承载分流请求消息,并向第一网络节点发送第二承载分流确认消息。
第二承载分流确认消息包括第三待承载业务组的信息,其中第三待承载业务组包括第二承载业务组中LPN能够承载的业务。
在LPN向第一网络节点发送第二承载分流确认消息之前,该方法还可以包括:
LPN从第二待承载业务组中筛选出,LPN能够承载的业务,得到第三待承载业务组的信息。对于E-RAB来说,即LPN从第二待承载E-RAB列表中筛选出,LPN能够承载的E-RAB对应的表项,得到第三待承载E-RAB列表。具体地,LPN判断第二待承载E-RAB列表中允许被接入的E-RAB的条件可以是LPN和第一网络节点间的信道状况。
实现时,第二承载分流确认消息还可以包括LPN侧与第二回程链路相关的网络接口的DRB配置信息,LPN侧与第二回程链路相关的网络接口的DRB的配置信息用于指示第一网络节点在与第二回程链路相关的网络接口上将待承载E-RAB的上行E-RAB对应的DRB配置为下行承载,将待承载E-RAB的下行E-RAB对应的DRB配置为上行承载。其中,下行承载用于承载LPN到网节点的用户面数据,上行承载用于承载第一网络节点到LPN的用户面的数据。
实现时,与第二回程链路相关的网络接口的DRB配置与现有的LTE技术相同,例如需要进行DRB ID、DRB在分组数据汇聚协议层、无线链路控制层、媒体访问控制层和物理层等上的配置,这里不再赘述。
需要说明的是,在另一种可行的实施方式中,LPN接收第二承载分流请求消息后,并不需要完成LPN侧与第二回程链路相关的网络接口的DRB配置,该方法还可以包括:
LPN根据第二承载分流请求消息,设置LPN侧与第二回程链路相关的网络接口上的DRB的配置信息。
此种情况下,在第一网络节点接收到第二承载分流确认消息后进行第一网络节点侧的待承载E-RAB在与第二回程链路的网络接口上的DRB配置时,LPN可以同步进行LPN侧与第二回程链路相关的网络接口上的DRB配置。
步骤504:第一网络节点接收LPN发送的第二承载分流确认消息。
其中,第二承载分流确认消息包括第三待承载业务组的信息,其中第三待承载业务组包括第二承载业务组中LPN能够承载的业务。第二分流确认消息用于通知基站第二回程链路已建立。
第二承载分流确认消息还可以包括第一网络节点侧与第二回程链路相关的网络接口的DRB配置信息,第一网络节点根据第二承载分流确认消息,将与第二回程链路相关的网络接口上的每一个待承载E-RAB的上行E-RAB对应的DRB配置为下行承载,并且将待承载E-RAB的下行E-RAB对应的DRB配置为上行承载。第一网络节点与LPN之间还可以采用空闲的上行DRB传输下行业务或采用空闲的下行DRB传输上行业务。
步骤505:第一网络节点向基站发送第一承载分流确认消息。
其中,第一承载分流确认消息包括第一待承载业务组中LPN和第一网络节点能够承载的业务的信息,即第一承载分流确认消息包括第三待承载业务组的信息。对于E-RAB来说,第一承载分流确认消息包括第三待承载E-RAB列表。第一承载分流确认消息用于通知基站,第一网络节点已经完成了第一回程链路的配置。
第一承载分流确认消息还可以包括待承载E-RAB的第一网络节点侧链路配置信息和LPN的身份识别信息,待承载E-RAB的第一网络节点侧链路配置信息可以包括下行隧道标识信息(例如下行隧道的GTP-TEID)和TNL address信息,基站根据下行隧道标识信息和第一承载分流确认消息中的TNL address信息建立第一回程链路的下行链路,第一回程链路的下行链路为基站到第一网络节点的单侧链路。
在本实施例中,第一承载分流确认消息可以作为第一承载分流请求消息的响应消息。
步骤506:基站接收第一承载分流确认消息,并完成第一回程链路和第二回程链路上的配置。
具体地,基站保存第三待承载E-RAB列表、待承载E-RAB的第一网络节点侧链路配置信息。
在另一种实现方式中,各个消息中的待承载E-RAB的信息也可以不采用列表进行保存和收发,而是直接以非列表的形式保存和发送。
步骤507:LPN和基站通过第一回程链路和第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据。
其中,基站通过第一回程链路分流的LPN与基站之间的用户面数据包括LPN通过第二回程链路和第一回程链路发送给基站的上行数据(即上行业务),以及基站通过第一回程链路和第二回程链路发送给LPN的下行数据(即下行业务)中的至少一种。第一回程链路和第二回程链路均包括上行链路和下行链路,其中,第一回程链路的上行链路为第一网络节点到基站的单侧链路,第一回程链路的下行链路为基站到第一网络节点的单侧链路。第二回程链路的上行链路为第一网络节点到LPN的单侧链路(即LPN的小区内的下行链路),第二回程链路的下行链路为LPN到第一网络节点的单侧链路(即LPN的小区内的上行链路)。
当基站与LPN之间有下行数据需要传输时,基站通过第一回程链路的下行链路,将下行数据发送给第一网络节点,第一网络节点将该下行数据通过第二回程链路的上行链路发送给LPN;当LPN与基站之间有上行数据需要传输时,LPN通过第二回程链路的下行链路将该上行数据发送给第一网络节点,第一网络节点再将该上行数据发送给基站。
本发明实施例通过在基站和LPN之间加入第一网络节点,第一网络节点与基站建立第一回程链路,与LPN建立第二回程链路,当基站与LPN之间下行业务量很大或者上行业务量很大时,基站和LPN之间可以通过第一回程链路和第二回程链路传输第一回程链路分流的用户面数据,保证了基站和LPN之间回程链路的链路容量,且基站与第一网络节点之间的非空中接口,不占用蜂窝网络的频谱,保证了第一回程链路上的网络容量,第一网络节点与LPN之间还可以采用空闲的上行DRB传输下行业务或采用空闲的下行DRB传输上行业务,保证了第二回程链路上的网络容量,从而也保证了基站和LPN之间回程链路上的网络容量,并且在本实施例中,第一网络节点可以直接从LPN上获取LPN能够承载的业务的信息,以建立第二回程链路,信令交互次数比较少,花费时间短。
实施例九
本发明实施例提供一种传输数据的方法,在本实施例中,基站与LPN之间不存在主回程链路,并且第一网络节点从基站获得LPN能够承载的业务的信息, 如图10所示,该方法包括:
步骤601:基站向第一网络节点发送第一承载分流请求消息。
具体地,该步骤与步骤501相同,这里不再赘述。
步骤602:第一网络节点接收第一承载分流请求消息,并向基站发送第一承载分流确认消息。
其中,第一承载分流确认消息包括LPN的身份识别信息和第二待承载业务组的信息。第一承载分流确认消息用于通知基站,第一网络节点侧的与第一回程链路相关的网络接口的配置已完成,并告知基站第一网络节点允许接入的所有待承载E-RAB对应的表项。
第一承载分流确认消息还可以包括待承载E-RAB的第一网络节点侧链路配置信息,基站根据第一网络节点侧链路配置信息配置第一回程链路的下行链路。具体地,第一网络节点侧链路配置信息包括下行隧道标识信息(例如下行隧道的GTP-TEID)和TNL address信息,基站根据下行隧道标识信息和第一承载分流确认消息中的TNL address信息建立第一回程链路的下行链路,第一回程链路的下行链路为基站到第一网络节点的单侧链路。
在第一网络节点向基站发送第一承载分流确认消息之前,该方法还包括:
第一网络节点根据第一承载分流请求消息,确定第二待承载业务组的信息,其中第二待承载业务组包括第一待承载业务组中第一网络节点能够承载的业务。
对于E-RAB来说,第一承载分流确认消息包括第二待承载E-RAB列表。具体地,第二待承载E-RAB列表至少包括一个表项,其每个表项中的E-RAB的信息可以携带E-RAB的ID信息和QoS需求信息。
其中,第一承载分流确认消息可以是第一承载分流请求消息的响应消息。
步骤603:基站接收第一网络节点发送的第一承载分流确认消息,并向LPN发送第二承载分流请求消息。
其中,第二承载分流请求消息包括第一网络节点的身份信息和第二待承载业务组的信息(即第二待承载E-RAB列表)。第二承载分流请求消息用于请求LPN根据第二待承载E-RAB列表,确定LPN侧与第二回程链路相关的网络接口上的DRB配置。
需要说明的是,由于第一网络节点与LPN之间并未进行信令交互,LPN无 法辨别第一网络节点,所以第二承载分流请求消息中还需要包括第一网络节点的身份信息。
步骤604:LPN接收第二承载分流请求消息,并向基站发送第二承载分流确认消息。
其中,在LPN接收到基站发送的第二承载分流确认消息之后,向基站发送第二承载分流确认消息之前,处理方法同步骤503,这里不再赘述。
第二承载分流确认消息包括第三待承载业务组的信息(即第三待承载E-RAB列表),其中第三待承载业务组包括第二承载业务组中LPN能够承载的业务。
第二承载分流确认消息还可以包括LPN侧与第二回程链路相关的网络接口上的DRB配置信息。其中,LPN侧与第二回程链路相关的网络接口上的DRB配置信息指示第一网络节点,在第一网络节点侧将与第二回程链路相关的网络接口上每一个待承载E-RAB的上行E-RAB对应的DRB配置为下行承载,并且将待承载E-RAB的下行E-RAB对应的DRB配置为上行承载。第一网络节点与LPN之间还可以采用空闲的上行DRB传输下行业务或采用空闲的下行DRB传输上行业务。
需要说的是,在该步骤中,LPN可以先不进行LPN侧的与第二回程链路相关的网络接口的DRB配置,而是在第一网络节点进行第一网络节点侧的与第二回程链路相关的网络接口的DRB配置时,同步完成。
步骤605:基站接收LPN发送的第二承载分流确认消息,并向第一网络节点发送第二承载分流配置消息。
其中,第二承载分流配置消息包括第三待承载业务组的信息(即第三待承载E-RAB列表),其还可以包括LPN侧与第二回程链路相关的网络接口上的DRB配置信息。
需要说明的是,第二承载分流配置消息可以是基站将接收LPN发送的第二承载分流确认消息,向第一网络节点直接进行的转发,为了便于描述,这里采用了不同的消息名称。
步骤606:第一网络节点接收第二承载分流配置消息,并向基站发送第二承载分流配置确认消息。
其中,第二承载分流配置确认消息用于告知基站,第一网络节点完成了第 一网络节点侧上的第二回程链路相应的网络接口的DRB配置。实现时,第二承载分流配置确认消息可以包括第三待承载E-RAB列表和第一网络节点侧与第二回程链路相关的网络接口上的DRB的配置信息,也可以不包括第一网络节点侧与第二回程链路相关的网络接口上的DRB的配置信息。
步骤607:LPN和基站通过第一回程链路和第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据。
具体地,该步骤同前述507相同,这里不再赘述。
本发明实施例通过在基站和LPN之间加入第一网络节点,且第一网络节点与基站建立第一回程链路,与LPN建立第二回程链路,当基站与LPN之间下行业务量或者上行业务量很大时,第一网络节点可以通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,从而保证了基站和LPN之间回程链路上的网络容量。与前述实施例八相比,虽然由基站向LPN发送第二承载分流请求消息,并接收LPN发送的第二承载分流确认消息后,再向第一网络节点转发LPN能够承载的业务的信息,增加了信令交互次数,但是通过基站转发,使基站较早获知第二回程链路上的网络接口的配置,便于基站对基站和LPN之间的回程链路的部署进行了解。
实施例十
本实施例提供一种传输数据的方法,在本实施例中,基站与LPN之间存在主回程链路和分流回程链路两条链路,并且由基站控制是否触发建立分流回程链路,如图11所示,该方法包括:

其中,基站判断是否触发建立分流回程链路,可以包括:
基站获取主回程链路的负载信息,主回程链路为基站与LPN之间的直接链路;实现时,主回程链路可以是LTE空口。
基站根据主回程链路的负载信息,判断是否向第一网络节点发送第一承载分流请求消息。当基站判定需要触发建立分流回程链路时,执行的操作可以是向第一网络节点发送第一承载分流请求消息。第一承载分流请求消息包括LPN的身份识别信息和第一待承载业务组的信息(即第一待承载E-RAB列表)。具体地,第一待承载E-RAB列表包括至少一个表项,其每个表项中的E-RAB的 信息可以包括E-RAB ID信息和QoS需求信息。
第一承载分流请求消息还可以包括待承载E-RAB的基站侧链路配置信息,待承载E-RAB的基站侧链路配置信息可以包括上行隧道标识信息(例如上行隧道的GTP-TEID)和TNL address信息,第一网络节点可以根据上行隧道标识信息和第一承载分流请求消息中的TNL address信息建立第一回程链路的上行链路,第一回程链路的上行链路为第一网络节点到基站的单侧链路。
实现时,基站可以通过监控主回程链路中的负载是否超过设定值,以判断是否向第一网络节点发送第一承载分流请求消息(即是否需要触发建立分流回程链路传输数据)。具体地,主回程链路中的负载状态可以是LPN主动上报给基站,也可以基站自己测量。设定值可以为主回程链路中用于传输的资源与主回程链路可用的总资源的比值的特定值。
需要说明的是,在前述实施例八和九中,基站与LPN之间不存在主回程链路,分流回程链路的建立均是基站控制完成的。
步骤702:基站向第一网络节点发送第一承载分流请求消息。
具体地,该步骤与步骤501相同,这里不再赘述。

具体地,该步骤与步骤503相同,这里不再赘述。
步骤706:第一网络节点接收第二承载分流确认消息,并向基站发送第二承载分流配置确认消息。
其中,第二承载分流配置确认消息用于通知基站,第一网络节点中与第二回程链路相关的网络接口的DRB配置已完成,第二承载分流配置确认消息包括第三待承载业务组的信息(即第三待承载E-RAB列表)。
步骤707:基站接收第二承载分流配置确认消息,完成分流回程链路的配置。
例如,保存第三待承载E-RAB列表和第一网络节点侧与第二回程链路相关的网络接口的DRB配置信息等。
在其他实现方式中,在步骤701执行之后,也可以直接采用实施例八或九中的方法,建立分流回程链路。
步骤708:LPN和基站通过第一回程链路和第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据。
具体地,该步骤同前述507相同,这里不再赘述。
本发明实施例通过在基站和LPN之间加入第一网络节点,且第一网络节点与基站建立第一回程链路,与LPN建立第二回程链路,当基站与LPN之间下行业务量或者上行业务量很大时,第一网络节点可以通过第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据,从而保证了基站和LPN之间回程链路上的网络容量。与前述实施例八和九相比,基站和LPN已经存在一条主回程链路,在主回程链路的负载比较大时,分流回程链路的建立可以分流一部分数据,保证基站与LPN之间的数据传输的畅通性。
实施例十一

在本实施例中,第一承载分流请求消息包括LPN的身份识别信息、第一待承载E-RAB列表和主回程链路的负载信息。其中,主回程链路为基站与LPN之间的直接链路。
第一待承载E-RAB列表至少包括一个表项,其每个表项中的E-RAB的信息可以包括E-RAB的ID信息和QoS需求信息。
在第一网络节点接收到第一承载分流请求消息后,该方法还包括:

第一网络节点根据主回程链路的负载是否超过预设门限,确定第二待承载业务组是否包括待承载E-RAB。当第一网络节点判断出主回程链路的负载超过 预设门限时,从第一待承载业务组中选择第一网络节点能够承载的E-RAB作为第二待承载E-RAB列表中的待承载E-RAB;否则,不执行该动作。
步骤802:第一网络节点向基站发送第一承载分流确认消息。
其中,第一承载分流确认消息包括第一待承载业务组中LPN和第一网络节点能够承载的业务的信息(即第二待承载E-RAB列表),第一承载分流确认消息用于通知基站建立与LPN之间的分流回程链路,并完成基站侧与第一回程链路相关的网络接口的配置。
容易理解地,在基站接收到不包括待承载E-RAB的第二待承载E-RAB列表时,表明不需要与LPN之间的分流回程链路。
第一承载分流确认消息还可以包括待承载E-RAB的第一网络节点侧链路配置信息,待承载E-RAB的第一网络节点侧链路配置信息可以包括上行隧道标识信息(例如,上行隧道的GTP-TEID)和传输网络层地址信息。基站根据第一网络节点侧链路配置信息配置第一回程链路的下行链路。

具体地,该步骤与步骤603相同,这里不再赘述。
步骤804:LPN接收第二承载分流请求消息,并向第一网络节点发送第二承载分流确认消息。
具体地,该步骤与步骤503相同,这里不再赘述。
步骤805:第一网络节点接收第二承载分流确认消息,并向基站发送第一承载分流配置消息。
其中,第一承载分流配置消息包括第三待承载E-RAB列表。第一承载分流配置消息用于通知基站,第二回程链路已建立。
步骤806:基站接收第一承载分流配置消息,并向第一网络节点发送第一承载分流配置确认消息。

在另一种实现方式中,第一承载分流配置确认消息中也可以不包括第三待承载E-RAB列表。
在另一种实现方式中,在步骤801执行之后,也可以直接采用实施例八或九中的方法,建立分流回程链路。
步骤807:LPN和基站通过第一回程链路和第二回程链路,传输基站通过第一回程链路分流的LPN与基站之间的用户面数据。
具体地,该步骤同前述507相同,这里不再赘述。
