本申请基于申请号为201610405263.X、申请日为2016年06月08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入本申请作为参考。
技术领域
本申请涉及通信技术领域,尤其涉及一种数据传输方法、装置及存储介质。
背景技术
目前,当用户设备(User Equipment,UE)不需要传输任何业务数据时,处于空闲(Idle)状态。Idle状态有利于UE节电,同时也避免UE移动时,向网络侧频繁发起切换流程,增加网络侧的信令处理负荷。
当第三方服务器需要向UE发送下行数据包时,基于下述流程建立数据连接:
如图1所示,第三方服务器将发给处于Idle状态的UE的下行数据包发送给分组数据网关(PDN Gate Way,PGW),PGW发送至服务网关(Serving GateWay,SGW),SGW缓存该下行数据包;SGW发送下行数据通知消息给移动性管理实体(Mobility Management Entity,MME)。这时,如果SGW收到该UE另外的下行数据包,SGW缓存这些数据包,但不再发送新的下行数据通知消息。MME发送寻呼(Paging)消息给每一个UE注册的跟踪区的基站(eNodeB)。eNodeB寻呼UE。UE触发业务请求过程,建立和网络侧的连接。至此,SGW与基站之间的S1-U下行数据通道建立。
上述流程中需要SGW、MME、和基站协商建立数据通道,如果下行数据间隔频繁到达,需要频繁协商数据通道,另外,需要SGW具有缓存下行数据的能力,直到SGW与基站之间的数据通道建立完成。显然,这种方式增加了网络侧的信令负荷及数据处理负担。
为减轻网络侧的信令负荷及数据处理负担,对于基于移动需求较弱的终端,特别是某些无移动性需求的终端(如电子报表用户),第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)提出了窄带蜂窝物联网(Narrow Band Internet of Things,NB-IOT)解决方案。这种解决方案提出了两种传输方案,如图2所示,一种是控制面方案(也称控制面优化方案):在这种方案下,无需建立S1-U承载,下行小数据包通过非接入层(Non-access stratum,NAS)信令随路传输至移动性管理实体(Mobility Management Entity,MME),然后发往UE,也即下行数据包的传输路径为第三方服务器→PGW→SGW→MME→基站→UE,相应地,控制面方案下的上行数据包的传输路径为UE→基站→MME→SGW→PGW→第三方服务器。另一种是用户面方案,这种传输方案则需要建立S1-U承载,下行数据包的传输路径为第三方服务器→PGW→SGW→基站→UE,上行数据包的传输路径为UE→基站→SGW→PGW→第三方服务器。其中,SGW/PGW属于用户面网元,MME属于控制面网元,基站属于接入网网元。上述解决方案中,控制面方案适合传输数据包较小的情况,而用户面方案适合数据包较大,传输时间间隔长的场景。
目前,针对特定的专网,NB-IOT解决方案会为其选择上述两种传输方案中的一种特定的传输方案,由于在该专网下,不同的UE可能具有不同的业务传输需求,即使同一UE在不同时刻的业务传输需求也不同,现有技术为特定的专网选择特定的传输方案的方式已无法满足不断多样化的业务场景需求。

下面结合说明书附图对本申请实施例作进一步详细描述。
实施例一、
如图3所示,为本申请实施例一提供的数据传输方法流程图,包括以下步骤:
S301:第一设备获取用户设备UE的业务相关信息。
本申请实施例中的第一设备是指网络侧中具有路径选择功能的装置。第一设备可以为以下网元中的任意一种:
第三方服务器;能力开放平台;域名系统(Domain Name System,DNS);数据库;网络侧中具有路径选择功能的独立的网元;控制面网元;控制面第二功能实体,其中控制面存在控制面第一功能实体和控制面第二功能实体,所述控制面第一功能实体管理UE的移动性上下文,所述控制面第二功能实体管理UE的会话上下文;第二用户面网元;接入网网元。
本申请实施例的数据库,可以为归属签约用户服务器(Home Subscriber Server,HSS),或策略数据库,或网络侧中具有数据管理功能的独立的网元。本申请实施例中,控制面网元可以是兼具移动性管理(Mobility Management,MM)功能(用于对UE移动性进行管理,通过MM可查找到UE的移动性上下文信息)和会话管理(Session Management,SM)功能(用于管理UE的用户面数据链路,为UE建立数据连接,分配相应的资源)的网元,移动性管理(Mobility Management,MM)功能和会话管理(Session Management,SM)功能也可以分别由两个独立的网元来承载,也即本申请实施例中的控制面第一功能实体和控制面第二功能实体。
上述业务相关信息可以包括以下信息中的一种或多种:
业务流描述信息;第三方标识信息;业务类型信息;流量类型信息;数据长度信息;UE类型信息;第三方设备类型信息;业务传输方案指示信息,用于指示采用用户面方案或控制面方案传输业务数据,所述用户面方案是指通过用户面和接入网传输业务数据的方案,所述控制面方案是指通过用户面、控制面和接入网传输业务数据的方案;UE和/或第三方服务器的位置信息。
上述业务流描述信息比如互联网协议(Internet Protocol,IP)五元组,统一资源定位符(Uniform Resource Locator,URL)或业务流标识(即标签)等。第三方标识信息包括第三方服务商标识信息(比如淘宝商城的主办方Sponsor的ID)和/或第三方服务商下的子服务商标识信息(比如淘宝商城中每一个商户service provider的ID);业务类型可以指具体应用的类型,比如网上银行业务、支付宝业务、爱奇艺视频、优酷视频等,可以用应用标识(Application ID)来表示业务类型。流量类型比如视频类型、音频类型等。数据长度信息可以指数据包的大小。UE类型比如数字电表、数字水表等。第三方设备类型比如视频内容服务器、数据采集系统等。基于UE和/或第三方服务器的位置信息,可以为UE选择一个距离UE和/或第三方服务器的位置最近的用户面网网元。
S302:第一设备确定与UE的业务相关信息对应的数据传输路径信息。
这里,数据传输路径信息可以包括业务传输方案信息和/或第一用户面网元信息;
其中,确定的业务传输方案为用户面方案或控制面方案,所述用户面方案是指通过用户面和接入网传输业务数据的方案,所述控制面方案是指通过用户面、控制面和接入网传输业务数据的方案。
在具体实施中,第一设备可以首先从数据库中获取UE的签约信息或策略信息,基于UE的签约信息或策略信息判断是否需要为UE建立数据连接(比如若UE没有启用数据连接功能,则不需要为UE建立数据连接),或者,根据UE发起的初次附着请求中的指示确定是否需要为所述UE建立数据连接;
在确定需要为所述UE建立数据连接后,再执行上述获取所述UE的业务相关信息,并确定与所述业务相关信息对应的数据传输路径信息的步骤,否则不为所述UE建立数据连接。
本申请实施例中,UE的数据传输路径的建立可以是由指示网元(优选地,第三方服务器)发起的,也可以是由UE发起的,具体可以有以下几种方式:
方式一:指示网元发起UE的数据传输路径的建立。
作为一种实施方式,第一设备为控制面网元或控制面第二功能实体;此时第一设备获取UE的业务相关信息,包括:第一设备接收指示网元发起的数据连接建立指示信息,根据所述数据连接建立指示信息,获取所述UE的业务相关信息;所述数据连接建立指示信息用于指示第一设备为所述UE确定与所述UE的业务相关信息对应的数据传输路径信息。
相应地,指示网元确定数据连接建立指示信息;所述数据连接建立指示信息用于指示第一设备为所述UE确定与所述UE的业务相关信息对应的数据传输路径信息;将所述数据连接建立指示信息发送给所述第一设备。
在上述实施方式中,所述数据连接建立指示信息中可以直接包括所述UE的业务相关信息;或者,所述数据连接建立指示信息中也可以不包括所述UE的业务相关信息,此时第一设备根据指示网元发起的数据连接建立指示信息,获取所述UE的业务相关信息,包括:
第一设备根据所述数据连接建立指示信息中的UE标识信息,在本 地、数据库、策略服务器、域名系统DNS服务器、第三方服务器、能力开放平台或网络侧独立的网元中,查询所述UE的业务相关信息。
在上述实施方式中,所述指示网元为以下任意一种:
第三方服务器;能力开放平台;域名系统DNS;数据库;网络侧中具有路径选择功能的独立的网元。
关于数据连接建立的触发方式的说明:
触发方式一:以指示网元为第三方服务器为例,第三方服务器可以通过控制面触发建立UE的数据连接:
情况一:所述第一设备为所述控制面网元。
具体地,所述控制面网元接收第三方服务器发起的数据连接建立指示信息可以是:控制面网元接收所述第三方服务器通过所述能力开放平台发送的所述数据连接建立指示信息。也即,第三方服务器将所述数据连接建立指示信息通过能力开放平台发送给控制面网元,此时数据连接建立指示信息的传输路径为第三方服务器→能力开放平台→控制面网元。
情况二:所述第一设备为控制面第二功能实体。
具体地,所述控制面第二功能实体接收指示网元发起的数据连接建立指示信息可以是:
控制面第二功能实体接收所述控制面第一功能实体发送的来自所述指示网元的数据连接建立指示信息,其中来自所述指示网元的数据连接建立指示信息中携带或者不携带所述UE的业务相关信息;或者,
控制面第二功能实体接收所述控制面第一功能实体发送的来自所述指示网元的数据连接建立指示信息以及所述控制面第一功能实体查询到的所述UE的业务相关信息,其中来自所述指示网元的数据连接建立指示信息中不携带所述UE的业务相关信息。
在具体实施中,控制面第一功能实体可以在接收到指示网元发起的数 据连接建立指示信息后,将所述数据连接建立指示信息发送给控制面第二功能实体,以使控制面第二功能实体为所述UE确定与所述UE的业务相关信息对应的数据传输路径信息。或者,控制面第一功能实体可以在接收到指示网元发起的数据连接建立指示信息后,基于所述数据连接建立指示信息中的用户设备UE标识信息查询到所述UE的业务相关信息;将所述数据连接建立指示信息以及所述UE的业务相关信息发送给控制面第二功能实体。
在上述过程中,若所述指示网元为第三方服务器,则所述控制面第一功能实体接收指示网元发起的数据连接建立指示信息,包括:所述控制面第一功能实体接收所述第三方服务器通过所述能力开放平台发送的所述数据连接建立指示信息。
也即,若所述第一设备为所述控制面第二功能实体,第三方服务器通过控制面触发建立UE的数据连接时,数据连接建立指示信息的传输路径为第三方服务器→能力开放平台→控制面第一功能实体→控制面第二功能实体。
触发方式二:以指示网元为第三方服务器为例,第三方服务器可以通过用户面触发建立UE的数据连接:
情况一:第一设备为所述控制面网元
具体地,第一设备接收指示网元发起的数据连接建立指示信息,包括:
所述控制面网元接收第二用户面网元发送的来自所述指示网元的数据连接建立指示信息,其中所述指示网元是通过用户面链路或控制面链路将所述数据连接建立指示信息发送给所述第二用户面网元的,来自所述指示网元的数据连接建立指示信息中携带或者不携带所述UE的业务相关信息;或者,
所述控制面网元接收所述第二用户面网元发送的来自所述指示网元的数据连接建立指示信息以及所述第二用户面网元查询到的所述UE的业务相关信息,其中所述指示网元是通过用户面链路或控制面链路将所述数据连接建立指示信息发送给所述第二用户面网元的,来自所述指示网元的数据连接建立指示信息中不携带所述UE的业务相关信息。
也即,若第一设备为所述控制面网元,第三方服务器通过用户面触发建立UE的数据连接时,数据连接建立指示信息的传输路径为第三方服务器→能力开放平台→第二用户面网元→控制面网元。这里的第二用户面网元与最终确定的数据传输路径中的第一用户面网元可以相同,也可以不同。
情况二:第一设备为控制面第二功能实体。
具体地,控制面第一功能实体接收第二用户面网元发送的来自所述指示网元的数据连接建立指示信息。之后,控制面第一功能实体可以将该数据连接建立指示信息发送给控制面第二功能实体,以使控制面第二功能实体为所述UE确定与所述UE的业务相关信息对应的数据传输路径信息。或者,在指示网元的数据连接建立指示信息不携带UE的业务相关信息时,控制面第一功能实体可以基于数据连接建立指示信息中的用户设备UE标识信息查询到UE的业务相关信息;将所述数据连接建立指示信息以及所述UE的业务相关信息发送给控制面第二功能实体。
在上述情况下,第三方服务器通过用户面触发建立UE的数据连接时,数据连接建立指示信息的传输路径为第三方服务器→能力开放平台→第二用户面网元→控制面第一功能实体→控制面第二功能实体。
综上,本申请实施例中,控制面网元或控制面第一功能实体可以直接通过能力开放平台接收第三方服务器的数据连接建立指示信息(控制面触发),也可以接收第二用户面网元发送的来自第三方服务器的数据连接建 立指示信息(用户面触发)。
方式二:UE发起数据传输路径的建立。
具体地,第一设备获取用户设备UE的业务相关信息,包括:第一设备接收用户设备UE发起的接入请求,基于所述接入请求,获取所述UE的业务相关信息。所述接入请求为初次附着请求或业务请求。
这里,所述接入请求中可以携带所述UE的业务相关信息;或者,
所述接入请求中可以不携带所述UE的业务相关信息,则基于所述接入请求,获取所述UE的业务相关信息,包括:所述第一设备根据所述接入请求中的UE标识信息,在本地、数据库、策略服务器、域名系统DNS服务器、第三方服务器、能力开放平台或网络侧独立的网元中,查询所述UE的业务相关信息。
在上述实施方式中,若所述第一设备为所述控制面第二功能实体,则所述控制面第二功能实体接收所述接入请求,包括:所述控制面第二功能实体接收所述控制面第一功能实体发送的所述接入请求,其中所述接入请求中携带或者不携带所述UE的业务相关信息;这里,控制面第一功能实体接收UE发起的接入请求,将其发送给控制面第二功能实体。
或者,所述控制面第二功能实体接收所述控制面第一功能实体发送的所述接入请求以及所述控制面第一功能实体查询到的所述UE的业务相关信息,其中所述接入请求中不携带所述UE的业务相关信息。这里,控制面第一功能实体基于接收的接入请求中的UE标识信息查询到UE的业务相关信息,将所述接入请求以及所述UE的业务相关信息发送给控制面第二功能实体。
以下内容对上述方式一和方式二都适用。
在具体实施中,若所述第一设备为所述控制面网元或控制面第二功能实体,所述第一设备确定与所述UE的业务相关信息对应的数据传输路径 信息,包括:在本地、数据库、策略服务器、域名系统DNS服务器、第三方服务器、能力开放平台或网络侧具有路径选择功能的独立的网元中,查询与所述UE的业务相关信息对应的数据传输路径信息。
作为一种实施方式A,确定的业务传输方案为用户面方案:
若所述第一设备为所述控制面网元或控制面第二功能实体,在S302所述第一设备确定与所述UE的业务相关信息对应的数据传输路径信息之后,还包括:所述第一设备向确定的数据传输路径中的第一用户面网元、所述UE附着的接入网网元、以及所述UE发送资源分配指示信息,所述资源分配指示信息用于指示采用用户面方案,并指示所述第一用户面网元、接入网网元、以及所述UE分配业务数据传输资源。
相应地,当接收到指示网元发送的数据连接拆除指示信息,根据所述数据连接拆除指示信息,指示所述UE接入的第一用户面网元及接入网网元释放为所述UE分配的业务数据传输资源。
作为另外一种实施方式B,确定的业务传输方案为控制面方案:
若所述第一设备为所述控制面网元或控制面第二功能实体,所述第一设备确定与所述UE的业务相关信息对应的数据传输路径信息之后,还包括:所述第一设备向确定的数据传输路径中的第一用户面网元发送资源分配指示信息,所述资源分配指示信息用于指示采用控制面方案为所述UE传输业务数据,并指示所述第一用户面网元分配业务数据传输资源。
相应地,在接收到指示网元发送的数据连接拆除指示信息后,根据所述数据连接拆除指示信息,指示所述UE接入的第一用户面网元释放为所述UE分配的业务数据传输资源。
在上述实施方式A和B中,所述资源分配指示信息中还包括业务流描述信息,用于指示保存所述业务流描述信息与分配的业务数据传输资源之间的映射关系,以便在接收到待发送业务数据时,根据待发送业务数据中 携带的业务流描述信息确定与之对应的业务数据传输资源。
在上述实施方式A和B中,所述资源分配指示信息中还包括服务质量(Quality of Service,QoS)策略,用于指示分配满足所述QoS策略的业务数据传输资源。
具体地,所述第一设备根据以下步骤获取所述QoS策略:
所述第一设备基于获取的所述业务相关信息,在本地、数据库、策略服务器、域名系统DNS服务器、第三方服务器、能力开放平台或网络侧中具有路径选择功能的独立的网元中查询与所述业务相关信息对应的QoS策略。
在实施例一中,若所述第一设备不是控制面网元或控制面第二功能实体,而是第三方服务器、能力开放平台、域名系统DNS、数据库、或网络侧中独立的网元,则所述第一设备确定与所述UE的业务相关信息对应的数据传输路径信息之后,还包括:将确定的数据传输路径信息发送给所述UE接入的控制面网元或控制面第二功能实体。此时,该数据传输路径信息中可以只包括业务传输方案信息,不包括第一用户面网元信息,由控制面网元或控制面第二功能实体基于该业务传输方案选择第一用户面网元信息。
进一步地,若所述第一设备为第三方服务器,则所述第三方服务器将确定的数据传输路径信息发送给所述UE接入的控制面网元或控制面第二功能实体,包括:所述第三方服务器通过能力开放平台将确定的数据传输路径信息发送给所述UE接入的控制面网元或控制面第二功能实体。
