具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员基于本申请所获得的所有其他实施例，都属于本公开保护的范围。
相关技术中，会话建立基于PPPoE/IPoE实现，用户设备接入认证流程与会话建立流程紧耦合，用户设备的每一次会话建立，都需要对PPPoE/IpoE用户认证信息进行鉴权认证，即，用户的每个签约会话在接入固定用户设备时都需要进行认证鉴权。且传统PPPoE和IPoE是2套完全不同的协议体系，互相不兼容，因此导致业务可扩展性有限。
为了解决上述问题，本公开实施例提出了一种会话建立系统、方法、电子设备及存储介质，以下进行详细说明。
图1为本公开实施例提供的会话建立系统的一种构架示意图，如图1所示，包括用户设备101和服务设备102，其中所述服务设备102包括：接入管理网元1021、会话控制网元1022及业务锚点1023，用户设备101和服务设备102进行交互既可实现会话建立。
具体交互过程如图2所示，在用户注册认证通过的情况下，用户设备101向接入管理网元1021发送会话建立请求。接入管理网元1021接收到会话建立请求后向会话控制网元1022转发会话建立请求，会话控制网元1022接收到会话建立请求后，获取用户设备的签约信息及中继代理信息；根据用户设备的签约信息及中继代理信息，在各业务锚点1023中选取为用户设备提供会话服务的目标业务锚点10231；生成目标业务锚点10231为用户设备101提供会话服务所需的第一配置信息，以及生成用户设备101接入目标业务锚点10231所需的第二配置信息；向目标业务锚点10231发送第一配置信息，向接入管理网元1021发送第二配置信息；接入管理网元1021向用户设备101转发第二配置信息，用户设备101按照第二配置信息对自身进行配置，并基于自身的配置，向目标业务锚点10231发送会话激活请求，目标业务锚点10231按照第一配置信息对自身进行配置，并基于自身的配置及会话激活请求，建立与用户设备101的会话。
其中，会话控制网元1022可以从签约信息服务器获取用户设备的签约信息以及从动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)服务器获取用户设备的中 继代理信息，上述第一配置信息为目标业务锚点10231为用户设备101提供会话服务所需要的，具体可以是流量识别转发策略、服务质量(Quality of Service，QoS)策略、本地会话表以及流量转发所需必要信息，如终端业务互联网协议地址(Internet Protocol Address，IP)、媒体存取控制位址(Media Access Control Address，MAC)、地址解析协议(Address Resolution Protocol，ARP)、邻居发现协议(Neighbor Discovery Protocol，NDP)信息和会话身份(identification,identity，ID)等；上述第二配置信息为用户设备101接入目标业务锚点10231所需要的，具体可以是流量识别转发策略和流量转发所需必要信息，如业务IP地址(Internet Protocol Address)分配、默认网关的IP、MAC、ARP、NDP信息、网域名称系统(Domain Name System，DNS)会话ID等。
传统的PPPoE或IpoE，不同的业务锚点必须位于不同的域，须同时在承载网建立相应的独立承载通道，规划、部署和维护相对复杂，本公开实施例提供的会话建立系统，可根据会话控制网元1022对业务锚点进行统一的会话控制，如对专用硬件锚点和虚拟化锚点进行统一的会话控制，可以实现虚实统管，可以根据用户需求按需选择核心或边缘的业务锚点，满足不同用户的差异化需求，使能更丰富的业务形态和业务增长点。
在一些实施例中，若因新业务需求引入新的会话类型，也可以基于本公开实施例提供的会话建立系统实现会话建立，具体为：根据新的业务需求，生成目标业务锚点为用户设备提供会话服务所需的新的第一配置信息，以及生成用户设备接入目标业务锚点所需的新的第二配置信息，然后向目标业务锚点发送新的第一配置信息，向接入管理网元发送新的第二配置信息既可，会话建立的后续流程可参考本公开实施例，相关技术中，通常使用PPPoE和IpoE等实现会话建立，而PPPoE和IpoE是2套完全不同的协议体系，互相不兼容，可扩展性有限，而根据本公开的一些实施例，不需要重新设计信令流程，因此可以增强业务可扩展性。
根据本公开的一些实施例，用户设备在注册认证通过的情况下向接入管理网元发送会话建立请求，可以实现用户注册认证流程与会话建立流程解耦，即不论用户设备有多少个签约会话，在接入固定终端时只需要进行一次认证鉴权，鉴权通过后可由会话控制网元根据签约信息统一完成锚点选择，由业务锚点响应会话建立请求，可以增强业务可扩展性，可使能更丰富的业务特性，如终端可漫游、更丰富的会话类型，会话类型包括但不限于互联网通信协议第四版(Internet Protocol version 4，IPv4)、互联网通信协议第六版(Internet  Protocol version 6，Ipv6)、IPv4v6、传统Ethernet(以太网)会话、非结构化会话，进而可以提升用户体验。
在一些实施例中，接入管理网元1021，还用于在用户设备注册认证通过后，向会话控制网元1022发送表示用户设备注册认证通过的第一消息，以使会话控制网元1022标记用户设备101注册认证通过；向用户设备101发送表示用户设备101注册认证通过的第二消息，以使用户设备101标记自身注册认证通过。如此，可在用户设备注册认证通过后，由用户设备发送会话建立请求，实现用户注册认证流程与会话建立流程解耦，可以增强业务可扩展性。
在一些实施例中，第一配置信息及第二配置信息中均包括会话标识；会话激活请求中包括会话标识。
第一配置信息所包含的会话标识可以是流量识别转发策略、QoS策略、本地会话表以及流量转发所需必要信息，如终端业务IP、MAC、ARP、NDP信息和会话ID等。第二配置信息包含的会话标识可以是流量识别转发策略和流量转发所需必要信息，如业务IP地址分配、默认网关的IP、MAC、ARP、NDP信息、DNS、会话ID等。
目标业务锚点，具体用于将第一配置信息中的会话标识添加到会话列表中；在接收到会话激活请求后，基于会话激活请求中的会话标识，查询会话列表；在会话列表中查询到会话激活请求中的会话标识、且目标业务锚点的会话资源允许添加新的会话的情况下，建立与用户设备的会话；否则，拒绝与用户设备的会话。
根据本公开的一些实施例，可以简化协议流程，会话建立所需要的配置信息可以由会话控制网元1022统一进行编排并下发到目标业务锚点10231和用户设备101，用户设备101只需要向目标业务锚点发送会话初始化、会话终结等请求既可，不需再通过多次握手协商会话建立所需的配置信息，通过统一的信令流程同时完成多个地址分配，如在IPv4/IPv6双栈业务场景下，可基于统一的信令流程同时完成IPv4和IPv6地址的分配；而在传统的PPPoE场景，需要分别通过IPCP(网际协议控制协议)和IPv6CP(IP控制协议和IPv6控制协议)获取地址，在传统的IPoE场景，需要分别通过DHCP和DHCPv6获取地址,所述DHCPv6是一个用来配置工作在IPv6网络上的IPv6主机所需的IP地址、IP前缀和/或其他配置的网络协议。
在一些实施例中，服务设备102还包括：DHCP服务器1025和签约信息服务器1024，如图3所示，为本公开实施例提供的会话建立系统的另一种构架示意图，DHCP服务器1025存储用户设备的中继代理信息，签约信息服务器1024存储用户设备的签约信息，由会话控制网元1022从签约信息服务器1024获取用户设备的签约信息，以及从DHCP服务器1025中获取用户设备的中继代理信息。中继代理信息可以是Option82(中继代理信息选项82)信息，包含用户设备的接入物理端口和接入设备标识等信息，用于获取用户设备位置和会话建立时的业务锚点选择决策。
图4为本公开实施例提供的会话建立系统的应用示例图，S1表示接入管理网元向会话控制网元通告用户注册认证通过信息，S2表示接入管理网元向终端(相当于图1所示系统中的用户设备)通告用户注册认证通过信息，S3表示终端向接入管理网元发起会话建立请求，S4表示接入管理网元向会控制网元中继会话建立请求，S5表示会话控制网元从签约信息服务器读取用户签约信息，S6表示会话控制网元从DHCP服务器读取用户Option82信息，Option82信息在为终端分配管理地址时已上送DHCP服务器，S7表示会话控制网元根据签约信息、Option82等信息选取业务锚点；S8表示会话控制网元向业务锚点下发配置，配置信息包括流量识别转发策略、QoS策略、本地会话表以及流量转发所需必要信息，如终端业务IP、MAC、ARP、NDP信息和会话ID等；S9表示会话控制网元通过接入管理网元向终端下发配置，配置信息包括流量识别转发策略和流量转发所需必要信息，如业务IP地址分配、默认网关的IP、MAC、ARP、NDP信息、DNS、会话ID等；S10表示会话控制网元通过接入管理网元向终端通告会话配置就绪信息；S11表示终端向业务锚点发起会话激活请求，请求报文中携带会话ID；S12表示业务锚点根据会话ID和本地会话表等信息，决策是否接受会话激活请求，其中会话激活后，业务锚点才为终端分配会话资源，以确保资源高效利用；S13表示业务锚点响应会话激活请求，响应方式包括接受和拒绝会话激活请求。
图5为相关技术中的会话建立系统的应用示例图，S14表示终端向BRAS池发起接入和会话建立请求向BRAS池发送PPPoE/IPoE信令报文，其中包含L2广播流量，S15表示BRAS池将PPPoE/IPoE用户认证信息发送到AAA(一种访问服务器)进行认证，S16表示AAA基于用户名、密码、Option82等信息对用户认证信息进行认证，S17表示AAA通过用户认证信息或拒绝用户认证信息；S18表示会话建立成功或失败，其中当AAA通过 用户认证信息，BRAS池接受会话建立请求，即会话建立成功，当AAA拒绝用户认证信息时，BRAS池拒绝会话建立请求，即会话建立失败。
本公开实施例提供的会话建立系统的信令交互图也可如图7所示，在图4中，业务会话承载在Underlay(底层)的L3VPN(三层虚拟专用网)上，图5中业务会话承载在Underlay的L2VPN(二层虚拟专用网)上，将业务会话承载在Underlay的L2VPN上会带来L2安全风险，增加承载网的部署和运维难度。而根据本公开的一些实施例，在业务锚点池化部署的场景下，业务会话可以统一承载在一个Underlay的L3VPN上，不需在IETF(Internet Engineering Task Force，互联网工程任务组)RFC8772(Request For Comments8772，IETF最终批准的标准文稿8772)定义的宽带接入服务器(Broadband Remote Access Server,BRAS)控制平面和用户平面(Control Plane,User Plane，CU)分离技术体制下，在Underlay需要部署L2VPN来承载业务会话，即Underlay层面只需要部署一个统一的L3VPN，如此可避免媒体存取控制位址(Media Access Control Address，MAC)欺骗、地址解析协议(Address Resolution Protocol，ARP)ARP泛洪等L2安全问题，简化承载网的规划、建设和维护，提升业务体验。
图5所示相关技术中，Option82用于用户名与接入电路绑定，并用于认证决策，主要目的是防止同一用户在多地同时登录造成的资源滥用，而在根据本公开的一些实施例，Option82主要用于会话控制网元获取终端位置信息，在用户有边缘锚点需求时，可根据其位置信息为其选择合适的业务锚点，根据本公开的一些实施例，防宽带资源滥用通过终端设备与用户非接入层(Non Access Stratum，NAS)信息绑定实现或者引入类似用户识别(Subscriber Identity Module，SIM)卡和机卡合一的机制实现,用户NAS信息包括用户身份、终端能力等信息。
在BRAS池化部署场景下，本公开实施例提供的会话建立系统可以规避L2安全问题，Underlay层面只需要部署一个统一的L3VPN，降低承载网的部署和运维难度。当用户同时存在上网和VoIP(语音电话)需求时，需要建立上网业务会话与语音业务会话，基于本公开实施例提供的会话建立系统的业务锚点选择机制，即会话控制网元，根据用户签约信息和注册认证状态等选择业务锚点，可很灵活地按需选择业务锚点并为终端下发分流策略，在承载网只需部署统一的Underlay L3VPN，即可实现多业务融合承载；而基于相关技术，如RFC8772需要分别为上网和语音业务部署独立的L2VPN承载相应业务，实施和维护复杂， 且存在L2安全风险。若用户存在时延敏感型业务需求，需要锚定在边缘锚点，基于本公开实施例提供的会话建立系统可敏捷实现，且不需要在承载网部署每业务每承载通道。
图6为本公开实施例提供的会话建立方法的一种流程图，如图6所示，包括以下步骤：
步骤S101，接入管理网元接收用户设备发送的会话建立请求，并向会话控制网元转发会话建立请求。
步骤S102，在用户设备注册认证通过的情况下，会话控制网元接收到会话建立请求后，获取用户设备的签约信息及中继代理信息；根据用户设备的签约信息及中继代理信息，在各业务锚点中选取为用户设备提供会话服务的目标业务锚点；生成目标业务锚点为用户设备提供会话服务所需的第一配置信息，以及生成用户设备接入目标业务锚点所需的第二配置信息；向目标业务锚点发送第一配置信息，向接入管理网元发送第二配置信息。
其中，业务锚点、接入管理网元、会话控制网元均包括与服务设备。
步骤S103，接入管理网元接收第二配置信息，并向用户设备转发第二配置信息；以使用户设备按照第二配置信息对自身进行配置，并基于自身的配置，向目标业务锚点发送会话激活请求。
步骤S104，目标业务锚点按照第一配置信息对自身进行配置，并基于自身的配置及会话激活请求，建立与用户设备的会话。
根据本公开的一些实施例，不论用户设备有多少个签约会话，在用户设备时只需要进行一次认证鉴权，鉴权通过后，可由会话控制网元根据签约信息，统一完成业务锚点选择，由业务锚点响应会话建立请求，可以实现用户注册认证流程与会话建立流程解耦，若因新业务需求引入新的会话类型，也可以基于本公开实施例提供的会话建立系统实现会话建立，可以增强业务可扩展性。
在一些实施例中，所述方法还包括：接入管理网元在用户设备注册认证通过后，向会话控制网元发送表示用户设备注册认证通过的第一消息，以使会话控制网元标记用户设备注册认证通过；向用户设备发送表示用户设备注册认证通过的第二消息，以使用户设备标记自身注册认证通过。
