Description

IP地址的配置方法、设备及系统
相关申请的交叉引用
本申请主张在2019年6月18日在中国提交的中国专利申请号No.201910528509.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种IP地址的配置方法、设备及系统。
背景技术
相关技术中，终端在建立PDU(Protocol Data Unit，协议数据单元)会话时，共有两种分配IP地址的方式，一种是SMF(Session Management Function，会话管理功能)为终端动态分配，SMF维护UE地址池；第二种是DHCP(Dynamic Host Configure Protocol，动态主机配置协议)分配，即在PDU会话建立结束后，UE发起DHCP分配地址请求，经由UPF(User Port Function，用户端口功能)转发给SMF，SMF转发给DHCP server(动态主机配置协议服务器)从而获取外部分配的IP地址。
在相关技术中，5G有一些场景，要求第三方为其接入终端指定固定的IP地址段。该地址段可能是私网地址段，如192.168.xx.xx。那么上述第一种分配方式是不支持的，原因是SMF维护的都是运营商规划的地址段。第二种DHCP的分配方式就要求第三方DN(Data Network，数据网络)自建DHCP服务器，而且SMF需要跟DHCP服务器互通。在运营商相关技术中的网络中，是不支持SMF与第三方DHCP互通的。

步骤122，向所述SMF发送所述获取签约信息请求的响应信息，所述响应信息携带所述IP地址，通过所述AMF以及无线接入网RAN将所述响应信 息发送给所述终端。
可选地，所述IP地址是所述第三方功能AF配置的私网IP地址，当然也可以是公网IP地址。本公开的实施例中的IP地址，可以是IPv4地址，也可以是IPv6前缀地址。
本公开的一可选实施例中，还可以包括：
步骤13，所述终端通过UPF(user port function，用户面功能)与第三方数据网络DN之间建立的隧道，与所述第三方DN传输数据。这里的隧道可以是VXLAN(虚拟可扩展局域网)隧道，也可以是N6隧道。
下面结合图2进一步的说明上述实施例的实现过程：
步骤1，AF调用NEF的接口，将一组5G VN中UE成员的GPSI(通用公共订阅标识符)、5GVN DNN(Data Network Name，数据网络名称)、切片辅助选择信息、外部组ID以及一段或者指定的IP地址配置给UDM。
步骤2，NEF将外部组ID映射为内部组ID，并将其他AF提供的信息写入UDM；
步骤3，UDM向NEF回复响应信息；
步骤4，NEF向AF回复响应信息；
步骤5，UE向AMF发起PDU会话建立请求；
步骤6，AMF调用SMF的PDU会话建立服务；
步骤7，SMF去UDM获取签约信息；其中，SMF根据UE SUPI(订阅永久标识符)号，获取UE的签约信息和5G VN组签约信息，其中包括获得指定给这个UE的一个IP地址或者一段IP地址中的一个。
步骤8，UDM回复响应信息给SMF，包括配置给UE的IP地址。
步骤9，SMF回复AMF，携带UE的IP地址。
步骤10，AMF将UE的IP地址经过RAN(Radio Access Network，无线接入网)传递给UE。
本公开的上述实施例，AF通过NEF向UDM配置5G VN组数据(5G VN group data)。5G VN组数据包括为5GVN组内的UE(以GPSI来标识)分配指定的一个IP地址或者一段IP地址中的一个。这些IP地址可以是AF指定的私网IP地址。
当UE以5G VN DNN发起PDU会话建立时，UDM将检测到该UE为5G VN组中的一个UE，并且为该UE分配指定的IP地址。
并进一步地，当第三方功能AF为该UE指定的IP地址为私网IP地址时，为保障数据路由，UPF与第三方的DN之间需要建立隧道，以确保数据包可以正确传输到指定的第三方DN中。该隧道的建立可独立于UE的PDU会话建立，可以为5G VN组粒度的隧道。从而实现了可以按照AF需求为UE分配指定的IP地址(公网或者私网地址)，并且无需第三方建设DHCP服务器。
