具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
参见图1,其示出了一种具有多接入5G的基础网络架构,可以称之为基于服务的网络架构(SBA,Service-Based Architecture)。如图1所示,用户设备(UE,User Equipment)通过(无线)接入网络((R)AN,(Radio)Access Network)接入到核心访问与移动性管理(AMF,Core Access and Moblity Management Function),UE也可以直接接入到AMF;AMF用于对网络的控制面消息进行处理,功能类似长期演进(LTE,Long Term Evolution)***中移动管理实体(MME,Mobility Management Entity)中的EPS移动性管理(EMM)。鉴权服务功能(AUSF,Authentication Server Function)类似LTE***中MME的健全功能,实现对UE的双向鉴权,支持统一的鉴权框架。用户面功能(UPF,Userplane Function)类似LTE***中服务网关S-GW和PDN网关P-GW的综合,与数据网络DataNetwork相连接。会话管理功能(SMF,Seesion Management Function)类似LTE***中的EPS会话管理ESM功能,主要针对会话进行管理、建立、修改和释放。从中可以看出,AUSF、AMF以及SMF的功能集合,类似于LTE***中的MME。此外,图1所示的结构中还包括:网络曝光功能(NEF,Network Exposure Function)、网元贮存功能(NRF,NF Repository Function)、策略控制功能(PCF,Policy Control Function)、统一的数据管理(UDM,Unified Data Management)和应用功能(AF,Application Function);其中,NEF用于向外部展示网络功能的一些能力,比如,监控能力、供给能力以及策略或计费能力;NRF能够支持服务发现功能;PCF支持管理网络行为的统一策略框架;UDM包括应用前端(FE)和用户数据仓库(UDR),FE可以访问UDR中的订阅用户信息,UDM的功能类似LTE***中的HSS,UDR提供订阅数据存储服务,应用前端FE提供基于数据的应用逻辑;AF用关于提供应用服务。
从上述架构中的网络可以看出,(无线)接入网络(R)AN与数据网络DataNework之间的架构可以称之为5G核心网,5G核心网中的网元称之为 5G核心网网元。5G技术中,允许终端通过多种接入网络的接入链路实现多连接数据传输,多种接入网络可以包括采用5G NR接入技术(NR,New Radio),LTE接入等符合3GPP标准的接入网络,也可以包括非3GPP标准的接入网络,例如无线保真(WIFI,WIreless-FIdelity)网络等。本实施例对此不做赘述。
为了在5G网络中针对业务进行多连接数据传输,本发明实施例在基于图1所示的网络架构中,额外设置业务接入管理节点(ATSSS/AT3SF),来对多连接传输的待传输数据流进行控制。以基于5G网络架构下的双连接(DC,Dual Connection)数据传输为例。当待传输数据流为下行数据流时,业务接入管理节点可以作为独立的网元实体设置在(R)AN与5G核心网网元之间;也可以以功能模块的形式分布在5G核心网具有与UE进行数据传输需求的网元中,例如UDM、SMF、PCF和UPF中。本实施例对此不做赘述。当待传输数据流为上行数据流时,业务接入管理节点作为独立的网元实体设置在(R)AN与UE之间,也可以作为UE的一个功能模块进行实现。在本发明实施例中,优选地,业务接入管理节点AT3SF可以分布于5G核心网中具有数据传输需求的网元内,比如UDM、SMF、PCF、SMF和UPF;也设置在UE中,参见图2所示的架构图,在图2中,符合3GPP标准的接入网络可以由5G基站gNB或LTE基站eNB等3GPP协议接入设备3GPP Access来提供;非3GPP标准的接入网络可以由WIFI接入点等非3GPP接入设备Non-3GPP Access来提供。
