本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution, LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
本公开实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,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装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。

首先对以下内容进行介绍:
图1是相关技术提供的广播报文转发场景的示意图,如图1所示,在相关技术中,PSA1收到数据网络(Data Network,DN)侧的广播报文后,通过N9/N3转发至UE1和PSA2。同理,PSA2也会收到此广播数据,PSA2向除来源(N6)之外的接口和隧道转发此广播报文,此时,PSA1又收到了从PSA2接收的相同的广播报文,PSA1会继续向DN侧转发和接入网(AN)侧转发,此时造成了如下问题:
UE1~UE3频繁接收重复广播数据包。
DN侧的广播源频繁的接收到自己发出的广播数据包。
若DN中设备是支持数据包转发的设备,可能还会造成PSA1、PSA2和DN设备间的广播环路。
在相关技术中的,会话管理功能(Session Management Function,SMF)对协议数据单元(Protocol Data Unit,PDU)会话锚点(PDU Session Anchor,PSA)下发的广播匹配转发规则如下(以PSA1为例,PSA2同理):
Match(PDR):
source Interface:接入侧,tunnel info:PSA1AN侧tunnel info
Action(FAR):
Output:internal interface{network instance}
internal interface{network instance}:
match(PDR):
source Interface:internal interface,internal dst_IP:广播IP
Action(FAR):
封装:复制数据包,{network instance}内所有RAN和N19的tunnel info(TEID,dst_IP),Source_IP:PSA1AN侧IP
其中,复制并转发的隧道不包含接收此数据的PSA1AN侧隧道。
图2是相关技术提供的第二层隧道协议的协议栈示意图,如图2所示,第二层隧道协议(英语:Layer Two Tunneling Protocol,缩写为L2TP)是一种虚拟隧道协议,通常用于虚拟专用网。N6接口可以基于这种隧道协议传输广播报文;
LAC(L2TP Access Concentrator):附属在交换网络上的具有PPP端系统和L2TP协议处理能力的设备(当地的ISP的NAS),用于传输信息包。其把从远端系统收到的信息包按照L2TP协议进行封装并送往LNS,同时也把从LNS收到的信息包进行解封装并发送给远端系统。
LNS(L2TP Network Server):通常为企业内部的边缘设备。通过在公网中建立L2TP隧道,将远端系统与LAC的PPP连接延伸到了企业网内部的LNS。
在核心网中,存在支持LAC功能的PSA,即将图2中的LAC可视为PSA,LNS视为通过N6连接设备的网关。当传输广播报文时,可以将私有互联网协议(Internet Protocol,IP)地址替换为广播IP封装在数据包中传输,即数据网络(Data Network,DN)中的组成员也可以收到广播数据包。同理,作为位置区码(location area code,LAC)的PSA也可能会收到作为DN侧作为广播源的成员发送的广播报文。
当同时支持N19和N6广播数据转发的5G LAN场景下,组成员和PSA会出现接收冗余广播收据包的问题,效率低下,严重浪费隧道资源,甚至可能造成广播数据包在发端PSA、其他PSA以及DN间来回传输,形成广播环。
因此,本公开实施例提供了一种数据传输处理方法及装置。
图3是本公开实施例提供的数据传输处理方法的流程示意图之一,如图3所示,该数据传输处理方法的执行主体可以是第一网元,比如可以是SMF,方法包括:

可选地,SMF确定第一策略后,比如在当PCF收到AF的请求信息以后,并且采用N6接口进行数据转发,PCF通过发送第一策略指示SMF采用N6路由用户面流量后,SMF可以判断DN侧是否存在组成员:
若不存在,则SMF判断当前同组的成员间是否存在N19隧道,若已经存在N19,则SMF向PCF返回相应的失败响应,即不再建立N6转发隧道。
若存在,SMF判断是否DN侧是否存在支持广播数据转发的设备:
若有,则SMF删除已经建立的N19隧道,建立N6转发隧道,删除N19 隧道后,各个PSA AN侧的组成员间通信传输基于DN侧的设备而不再基于N19;
若无,则采用其他相关技术。
