具体实施方式
下面先对本发明实施例所涉及的通信系统的架构示意图进行描述,其中,通信系统主要网络功能实体包括用户终端、接入网设备、移动边缘计算平台、控制面网元、策略与计费执行设备/用户面网关设备、业务能力开放平台、策略与计费功能设备、策略与计费执行设备、应用服务器等,为了便于理解本发明实施例,对本发明实施例涉及的相关网元或相关信息进行具体说明。
(1)用户终端(User Equipment,UE):是指可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网设备进行通信的设备,例如,用户终端可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动通信设备,它们与无线接入网交换语音和/或数据。
(2)接入网设备(Access Network function):可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。其可实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能。例如,可以是全球移动通信系统(Global System for Moblie Communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),本发明并不限定。其中,eNodeB可以和服务网关(Serving Gateway,SGW)相连,用于传送用户数据,也可以和移动管理实体(Mobility Management Entity,MME)相连,实现无线接入承载 控制等功能。
(3)移动边缘计算平台(Mobile Edge Computing,MEC):移动边缘计算平台是在靠近网络边缘的位置,其能够为应用提供更低时延与更大的带宽,同时还能够通过能力开放功能向应用服务器提供实时无线网络信息,例如用户位置、小区负荷信息等。该设备的名称并不作具体限定,能够实现该功能的均可以称为移动边缘计算平台。移动边缘计算平台允许内容、服务和应用的数据流加速,运营商可以向应用服务器开启无线网络以支持应用于服务、企业网以及垂直业务。
移动边缘计算平台可以包含以下三种构架:第一种,由业务能力开放功能模块构成;第二种,由用户面功能模块/网关和业务能力开放功能模块构成;第三种,由用户面功能模块/网关、业务能力开放功能模块和应用层功能模块/应用服务器构成。其中,用户面功能模块/网关,是负责接收与转发用户面数据流,也可以包含路由管理功能,比如确定路由规则(如哪些数据流由通过移动边缘计算平台本地路由的数据流,哪些数据流需通过传统的通信网络)等;业务能力开放功能模块,是指应用服务器通过其获取通信网络的信息(如接入网的拥塞状态或者用户终端的位置信息);应用层功能模块/应用服务器,是负责为用户终端提供数据流的发送入口。另外移动边缘计算平台也可以具有网络地址转换(Network Address Translation,NAT)功能。本申请中主要以第三种构架为例,在第三种构架下,全文中所涉及的移动边缘计算平台与应用服务器之间的信息交互,具体是指移动边缘计算平台中的业务能力开放功能模块或移动边缘计算平台中的网关与部署在移动边缘计算平台内的应用服务器之间的信息交互。
以移动边缘计算平台的第三种构架为例,在SAE系统中,移动边缘计算(Mobile Edge Computing,MEC),其是在更靠近网络边缘的位置提供IT与云计算能力。其中,MEC包括网关(Gateway,GW)、移动边缘计算平台的业务能力开放功能模块(MEC Service Capability Exposure Function,MEC-SCEF)和应用服务器(over the top,OTT),分别对应于移动边缘计算平台的用户面功能模块/网关、业务能力开放功能模块和应用层功能模块/应用服务器。
(4)控制面网元(Control Plane Function):主要负责用户即会话管理的所有控制平面功能,如SAE中的MME,MME可以包括网络附属存储(Network Attached Storage,NAS)信令及安全,跟踪区列表(Tracking Area List)的管理,PGW与SGW的选择等。
(5)用户面网关设备(User Plane Function):主要负责提供用户的会话管理和承载控制、数据转发、IP地址分配以及用户接入等功能,例如,用户面网关设备可以是SAE中的PGW,其作为外部网络发送给用户终端数据的入口,负责用户终端IP地址分配,用户终端的数据报文过滤、速率控制、生成计费信息等。
(6)业务能力开放平台(Network Exposure Function):主要负责第三方应用服务器(简称,应用服务器)的认证授权、计费和与网络侧网元的信息交互、信息隐藏以及封装调用,如SAE中的业务能力开放功能实体(Service Capability Exposure Function,SCEF),能够安全地向第三方开放服务与网络能力的接口,提供一种开放业务能力的发现机制,使应用服务器可通过SCEF获取通信网络的信息。
(7)策略与计费功能设备(Policy and charging Function):主要负责策略和计费控制决策。例如SAE中的策略与计费规则功能(Policy and Charging Rules Function,PCRF)是业务数据流和IP承载资源的策略与计费控制策略决策点,它为策略及计费执行功能(Policy and Charging Enforcement Function,PCEF)选择及提供可用的策略和计费控制决策。
(8)策略与计费执行设备(Policy and charging Enforcement Function):主要负责业务数据流的策略管理和执行等。例如SAE中的PCEF,其主要包含业务数据流的检测、策略执行和基于流的计费功能。该功能实体位于网关,例如通用分组无线服务(General Packet Radio Service,GPRS)的网关GPRS支持节点(Gateway GPRS Support Node,GGSN)网关、核心网分组演进(Evolved Packet Core,EPC)的PGW、无线局域网(Wireless Local Area Network,WLAN)中是分组数据网关(Packet Data Gate way,PDG),也可独立部署。
(9)应用服务器:即第三方应用服务器,由第三方通过开放的应用程序编程接口(Application Programming Interface,API)向用户提供各种服务的应用服务器。本发明实施例中,应用服务器可以指本地应用服务器。
(10)数据流描述符:可以是三元组信息如应用服务器的IP地址、端口号和协议类型,也可以是数据流的应用标识等。
(11)用户终端的标识信息:指可以用于设备用户终端的信息,可以是用户终端的IP地址、私网地址、或临时标识等等,也可以是移动台综合业务数字网 号码(Mobile Station Integrated Services Digital Network Number,MSISDN)或国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)等。本申请中,不同网元中之间传输的用户终端的标识信息在形式上可以相互转换,例如,应用服务器向移动边缘计算平台发送用户终端的标识信息,该用户终端的标识信息可以为用户终端的IP地址,移动边缘计算平台可以将该用户终端的IP地址转换为私网地址,并根据该私网地址确定MSISDN,然后再发送给策略与计费功能设备,这时策略与计费功能设备接收到的用户终端的标识信息则为MSISDN。
(12)数据流模板(Traffic Flow Template,TFT)用于描述数据传输通道上的数据流的特征。在移动边缘计算平台接收到数据流后,可以将符合该数据流描述符特征的数据流绑定到相应的数据传输通道上。需要说明的是,本发明中采用SAE中术语“数据流模板(TFT)”来描述数据传输通道与数据流的绑定关系,实际上,本发明不限制该术语的名称,也可以采用其它的名称来描述数据传输通道与数据流的绑定关系。本发明中,为了描述方便,以TFT作为术语描述。
本申请中,所述控制流规则可以由策略与计费功能设备生成并发送给其它网元,该步骤也可以理解为,策略与计费功能设备生成所述控制流规则,并向其它网元安装所述控制流规则。
本发明实施例中的通信系统主要以SAE和未来网络系统为例进行说明。
请参见图1a,图1a为本发明的一个实施例提供的SAE的架构示意图。如图1a所示,SAE架构中的eNB、MME、MEC、SGW、PCEF/PGW、PCRF和SCEF分别对应于本发明中所提到通信系统中的接入网设备、控制面网元、移动边缘计算平台、服务网关、策略与计费执行设备/用户面网关设备、策略与计费功能设备以及业务能力开放平台,本申请以SAE架构为例进行说明。从逻辑功能上分,MEC包括平台层,中间层和应用服务器,中间层主要包括能力开放、本地网关和路由管理。其中,能力开放是指应用服务器通过其获取通信网络的信息如接入网的拥塞状态或用户终端的位置信息等;本地网关类似于PGW,是应用服务器向用户终端发送数据流的入口;路由管理用于确定数据路由规则,如哪些数据流由MEC处理,哪些需要通信网络的核心网络设备处理。
在通信过程中,用户终端发送的数据流会通过eNB发送到通信网络中,SAE中的数据流传输路径主要包括以下两种:第一种是数据流经过MEC的GW到应 用服务器;第二种是数据流经过核心网的各网元如SGW、PGW到应用服务器。从用户终端到应用服务器(如图1a中的实线所示)的上行数据流可以通过现有技术获取相应的数据传输通道,将数据流传输至应用服务器。而对于从应用服务器到用户终端(如图1a中的虚线所示)的下行数据流,如何灵活地选择数据传输通道以获取相应的服务质量则成为当前亟需解决的问题。
请参见图1b,图1b为本发明的一个实施例提供的未来网络系统的架构示意图。如图1b所示,未来网络系统的架构中的本地用户面功能实体对应于本发明中的移动边缘计算平台的相关功能,具体的,本地用户面功能和应用服务器分别对应于移动边缘计算平台的用户面功能和应用层功能,业务能力开放功能实体(业务能力开放平台)未示出。本地用户面功能实体将数据流本地路由到应用服务器,而不经过远程用户面功能实体。
在通信过程中,用户终端发送的数据流会通过接入网络(Access Network)发送到通信网络中,通信网络中的数据流传输路径主要包括以下两种:一种是数据流经过本地用户面功能实体和远程用户面功能实体传输到外部网络中;第二种是数据流经过本地用户面功能实体传输到应用服务器中。其中,第二种在经过本地用户面功能实体与应用服务器之间数据流传输时,从用户终端到应用服务器(如图1b中的实线所示)的上行数据流可以通过现有技术将其绑定相应的数据传输通道上发至应用服务器。而对于从应用服务器向用户终端(如图1b中的虚线所示)传输的下行数据流,如何灵活地选择数据传输通道以获取相应的服务质量则成为当前亟需解决的问题。
本发明实施例提出来一种数据传输方法,用于解决上述问题,具体阐述见后续实施例。本发明实施例中,为了描述方便,以承载作为据传输通道的例子进行描述,但本发明并不限于承载,也可以是其它的数据传输通道。

其中,用户终端的标识信息可以是用户终端的IP地址等多种形式,在不同网元之间传输时可以进行不同的转换。例如,移动边缘计算平台接收到应用服务器发送的用户终端的标识信息,该用户终端的标识信息可以是用户终端的IP地址,这时,若移动边缘计算平台部署有NAT功能,则移动边缘计算平台可以根据用户终端的IP地址通过NAT功能获取该用户终端的私网地址,并根据该私网地址确定MSISDN/IMSI,或建立与MSISDN/IMSI的对应关系。移动边缘计算平台可以将转换后的用户终端的标识信息如MSISDN发送出去。

具体的,若所述移动边缘计算平台与所述策略与计费功能设备直接出接口,则所述移动边缘计算平台可以直接向策略与计费功能设备发送所述数据流描述符以及所述用户终端的标识信息。或者,所述移动边缘计算平台向业务能力开放平台发送所述数据流描述符以及所述用户终端的标识信息,所述业务能力开放平台可以将接收到的所述数据流描述符以及所述用户终端的标识信息发送给所述策略与计费功能设备。
可选的,所述移动边缘计算平台可以向策略与计费功能设备发送所述用户终端的数据流的目标服务质量请求,所述目标服务质量请求包括所述数据流描述符以及所述用户终端的标识信息。进一步可选的,所述目标服务质量请求还可以包 括第二服务质量。
S103、所述策略与计费功能设备根据所述数据流描述符和所述用户终端的标识信息为所述用户终端生成数据流控制规则。
具体的,所述策略与计费功能设备根据所述用户终端的标识信息获取用户终端的签约信息,该签约信息也用于生成数据流控制规则。数据流控制规则可以是策略与计费控制(Policy and Charging Control,PCC)规则。
其中,所述数据流控制规则包含数据流标识以及所述策略与计费功能设备为所述数据流生成的第一服务质量。具体的,第一服务质量可以通过以下两种方式生成:第一种,由策略与计费功能设备为所述数据流所生成,例如根据用户终端的签约数据等等,为所述数据流生成第一服务质量;第二种,如果步骤S102中,移动边缘计算平台提供了第二服务质量,策略与计费功能设备在接收到移动边缘计算平台从应用服务器获取到的第二服务质量后,再结合网络中数据流的服务质量信息以及网络状态信息等,确定第一服务质量,其中,第一服务质量可以与第二服务质量相同,也可以不同。
S104、所述移动边缘计算平台获取所述用户终端的数据流模板TFT和数据传输通道的标识信息,所述数据流模板TFT是根据来自所述策略与计费功能设备的数据流控制规则生成的,其中,所述数据流模板TFT包括所述数据流描述符。
其中,所述移动边缘计算平台通过以下两种方式获取所述用户终端的数据流模板TFT和数据传输通道的标识信息的:
第一种:所述移动边缘计算平台获取策略与计费执行设备/用户面网关设备根据来自所述策略与计费功能设备的数据流控制规则生成的数据流模板TFT,和确定的数据传输通道的标识信息;具体的可以包括步骤S105~S107。
第二种:所述移动边缘计算平台根据来自所述策略与计费功能设备的数据流控制规则生成数据流模板TFT,并确定数据传输通道的标识信息;具体的可以包括步骤S108和S109。
S105、所述策略与计费功能设备向策略与计费执行设备发送所述控制流规则。
相应的,所述策略与计费执行设备接收策略与计费功能设备发送的所述控制流规则。
S106、所述策略与计费执行设备根据发送的所述控制流规则生成数据流模板TFT,并确定数据传输通道的标识信息。
其中,所述数据流模板TFT包括所述数据流描述符。所述数据传输通道为所述数据流提供所述第一服务质量,所述第一服务质量,为策略与计费执行设备为业务数据流提供的服务质量。
具体的,策略与计费执行设备可以根据数据流传输通道的绑定规则,比如将服务质量类标识(QoS Class Identifier,QCI)/分配与保留优先级(Allocation And Retention Priority,ARP)相同的数据流绑定在同一个数据传输通道(比如,承载),获得数据流传输通道的标识信息,完成绑定之后,根据绑定在同一个数据传输通道的数据流标识生成了TFT,并记录该数据传输通道的标识与TFT的对应关系。
当数据流申请服务质量时,可能存在两种情况:第一种,若当前存在能够绑定该数据流的数据传输通道,则设备可以发起修改TFT的过程,将该数据流绑定在该数据传输通道中;第二种情况,若当前不存在能够绑定该数据流的数据传输通道,策略与计费执行设备可以发起新建数据传输通道的过程,这时设备可为该数据传输通道分配数据传输通道的标识,同时将该数据流对应的数据传输通道中绑定的应用数据流的描述符集成生成TFT,将记录该TFT与数据传输通道的标识的对应关系。
S107、所述策略与计费执行设备向所述移动边缘计算平台发送数据流模板TFT和数据传输通道的标识信息。后续执行步骤110。
