具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
基于WWC技术固网家庭网关既可以接入到有线接入网络(Wireline-Access Network，W-AN)，也可以接入到无线接入网络(Radio Access Network，RAN)。比特差错通常是成串出现的。对于有线侧，固网住宅网关(Fixed Network-Residential Gateway，FN-RG)或5G家庭网关(the 5th Generation-Residential Gateway，5G RG)的设备接入有线接入网络后，可以通过新增的5G AGF实现与5G无线核心网的互通。根据标准规范，5G-RG支持N1接口协议，通过5G AGF的N2接口可实现与5G核心网通信，而FN-RG不支持N1接口协议，需通过5G AGF支持N1及对FN-RG的N1代理实现与5G核心网的通信。
5G技术中心的AGF为转控分离的虚拟网络功能(Virtualized Network Function，VNF)，控制面通过N1接口封装到N2接口实现到5G核心网AMF的注册认证，用户面通过N3接口接入5G核心网用户面功能(User Plane Function，UPF)。根据第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准规定，N1接口运行NAS协议，N2接口运行流控制传输协议(Stream Control TransmissionProtocol，SCTP)协议，N3接口运行通用分组无线业务 (General Packet Radio Service，GPRS)隧道协议(GPRS Tunneling Protocol，GTP-U)。有线侧需要运行N1接口NAS协议，在这种情况下，有线侧NAS信息的传输是用户接入核心网和实现认证注册的关键环节。在此过程中，还需要为UE接入网络创建相应的接入资源。对于NAS系统信息和需通过底层传输控制协议传输到5G AGF进行处理的相关NAS信息，缺乏有效的机制来传输，导致NAS信息传输的可靠性低，影响接入和移动管理功能(Access and Mobility Management Function，AMF)对UE的注册认证，也影响到接入资源的创建和使用。
在本申请实施例中提供一种信息传输方法，应用于UE，通过VSP协议报文封装NAS信息及AS参数信息并通过VSNCP协议封装有线接入网络控制面通道建链信令，以通过有线接入网络控制面通道承载VSP协议报文的传输，从而实现NAS信息及AS参数信息到AGF的传输，提高NAS信息及AS信息传输的可靠性；AGF在获得NAS信息后可与AMF通信，进而实现用户的注册认证；AGF在获取到AS信息后，完成有线侧资源协商，提供有效的接入资源。
图1为一实施例提供的一种信息传输方法的流程图，如图1所示，本实施例提供的方法包括步骤110-130。
在步骤110中，将非接入层NAS信息及AS参数信息封装在厂商特定协议VSP协议报文中，所述NAS信息包括NAS系统信息和NAS定制信息，所述AS参数信息用于有线侧资源协商。
在步骤120中，将有线接入网络控制面通道建链信令封装在设备商特定网络控制协议VSNCP协议报文中。
在步骤130中，通过所述VSP协议报文和所述VSNCP协议报文传输所述NAS信息及AS参数信息。
本实施例中，NAS信息及AS参数信息封装在VSP协议报文中，NAS信息及AS参数信息的传输是在5G-RG和AGF之间的传输。封装在VSP协议报文中的数据根据处理方式的不同可以分为两类：一类是可以由AGF处理的NAS定制信息及AS参数信息，分别用于对AMF的选择和有线侧的网络资源的协商；一类是AGF不做直接处理、需要AGF透传的NAS系统信息，通过AGF的N2接口可以将其发送至AMF，用于实现用户的注册认证请求处理、用户注册取消或注册服务请求等。AS参数信息包括：在有线侧用户面资源创建的过程中，在5G-RG及AGF之间进行资源协商需要携带的资源参数，例如物理资源、本地策略等。
NAS系统信息包括UE发送到接入网络(Access Network，AN)的用户签 约信息，例如接入网络(AN)参数和注册请求(Registration Request)信息等，无线资源控制(Radio Resource Control，RRC)协议可用于NAS系统信息的广播；NAS定制信息包括在RRC建链过程中UE根据RRC协议需要封装的、从NAS上层通知到传输层并根据传输层控制协议传输到网络侧的NAS相关的系统信息，例如临时移动用户标识(Temporary Mobile Subscriber Identity，TMSI)、公共陆地移动网络(Public Lands Mobile Network，PLMN)等。
VSNCP协议报文中封装了有线接入网络控制面通道建链信令，在通过VSP协议报文传输NAS信息之前，可与AGF建立有线接入网络控制面通道，以此承载VSP协议报文的传输。
本实施例的信息传输方法提供了有效的NAS信息及AS参数信息传输机制，采用VSP协议报文和VSNCP协议报文建立有线接入网络控制面通道并传输NAS系统信息及NAS定制信息，提高了NAS信息传输的可靠性；AGF在获取到定制NAS信息及AS参数信息后可进行转发或实现对AMF的选取，使得AMF在获取NAS信息后实现对UE用户的注册认证，并完成有线侧的资源协商。
图2为一实施例提供的VSNCP协议报文格式的示意图。VSNCP是用于厂商特性的协议，封装在PPP的信息字段，对应的协议字段(Protocol Field)的值设置为805b(VSNCP)。如图2所示，VSNCP协议报文包括：编码(Code)字段：8bits，用于标识链路控制协议(Link Control Protocol，LCP)包的类型，例如是请求包还是应答包，字段值1-7分别对应于Configure-Request、Configure-Ack、Configure-Nak、Configure-Reject、Terminate-Request、Terminate-Ack、Code-Reject，其他值都会被回复Code-Reject；机构唯一识别符(OUI)字段：用于表征运营商特性；标识(Identifier)字段：LCP包的请求包或应答包的标识，便于匹配；长度(Length)字段：标识LCP包特定数据的大小；数据(Data)字段：用于为报文携带数据信息。
在一实施例中，所述VSNCP协议报文包括OUI字段，OUI字段用于指示有线接入网络控制面通道的建链；所述OUI字段由互联网数字分配机构IANA指定。
本实施例中，对于VSNCP协议报文承载NAS信息及AS参数信息传输的情况，扩展OUI字段，UE预先与IANA申请，由IANA指定一个特定的OUI字段值，该字段值从CF0000系列中指定，例如为CF0001。
在一实施例中，VSNCP协议报文包括编码字段；所述编码字段满足以下至少之一：在编码字段为第三设定值的情况下，VSNCP协议报文用于传输有线接入网络控制面通道的建链请求信息；在编码字段为第四设定值的情况下，VSNCP协议报文用于传输有线接入网络控制面通道的建链响应信息；在编码字段为第 五设定值的情况下，VSNCP协议报文用于传输有线接入网络控制面通道的建链响应拒绝信息。
本实施例中，对于VSNCP协议报文承载NAS信息传输的情况，扩展编码字段，编码字段为不同的值表示VSNCP协议报文用于传输不同的建链信息，例如，在编码字段的值为8(对应bits位1000)的情况下，VSNCP协议报文用于NAS有线接入网络控制面通道的建链请求(Connection-Request)信息的传输；在编码字段的值为9(对应bits位1001)的情况下，VSNCP协议报文用于NAS有线接入网络控制面通道的建链响应(Connection-Accept)信息的传输；在编码字段的值为10(对应bits位1010)的情况下，VSNCP协议报文用于NAS有线接入网络控制面通道的建链响应拒绝(Connection-Reject)信息的传输。
在一实施例中，VSNCP协议报文包括数据字段；所述数据字段满足以下至少之一；在编码字段为第三设定值的情况下，数据字段用于封装所述建链请求信息；在编码字段为第四设定值的情况下，数据字段用于封装所述建链响应信息；在编码字段为第五设定值的情况下，数据字段用于封装所述建链响应拒绝信息。
本实施例中，对于VSNCP协议报文承载NAS信息传输的情况，扩展数据字段，数据字段封装的建链信息与编码字段对应，例如，在编码字段为第三设定值的情况下，Data字段用于封装建链请求信息；在编码字段为第四设定值的情况下，Data字段用于封装建链响应信息；在编码字段为第五设定值的情况下，Data字段用于封装建链响应拒绝信息。
在一实施例中，VSNCP协议报文包括OUI字段；在OUI字段为第一标识的情况下，VSNCP协议报文用于承载NAS系统信息的传输；在OUI字段为第二标识的情况下，VSNCP协议报文用于承载NAS定制信息和AS参数信息的传输。
本实施例中，VSNCP协议报文还包括长度字段和数据字段；所述长度字段和数据字段用于封装NAS系统信息，或用于封装NAS定制信息及AS参数信息。
本实施例中，对于NAS信息及AS参数信息的处理，也可以只通过扩展OUI字段实现，包括：第一标识(OUI-X)用于标识承载NAS系统信息，第二标识(OUI-Y)用于标识承载NAS定制信息及AS参数信息。VSNCP协议的编码字段依然复用原LCP协议字段。在进行VSNCP控制面通道建链的过程中，5G-RG侧发送VSNCP协议报文编码字段值为1的Configure-Request报文到AGF，AGF回复VSNCP协议报文编码字段值为2的Configure-ACK报文到5G-RG，VSNCP控制面通道建链成功。如果AGF对收到的所述VSNCP协议报文编码字段值为 1的Configure-Request报文处理异常，回复VSNCP协议报文编码字段值为3的Configure-Reject报文到5G-RG，VSNCP控制面通道建链被拒绝。

在上层NAS信息提供了PLMN标识(PLMN-Identity)的情况下，NAS定制信息中包含PLMN信息，该PLMN信息存储在系统信息块(System Information Blocks，SIB)的SIB1的PLMN标识表(PLMN-Identity List)选取的PLMN信息中，将该PLMN标识的值设置为PLMN信息并发送到网络侧。
在上层NAS信息提供了注册(Registered)AMF的情况下，NAS定制信息包含Registered AMF信息并被发送到网络侧。
在上层NAS信息提供了S-NSSAI信息的情况下，NAS定制信息包含S-NSSAI信息并被发送到网络侧。

在本申请实施例中还提供一种信息处理方法，应用于AGF。图4为一实施 例提供的一种信息处理方法的流程图，如图4所示，本实施例提供的方法包括步骤210和步骤220。
在步骤210中，接收VSP协议报文和VSNCP协议报文，所述VSP协议报文中封装有NAS信息及AS参数信息，所述AS参数信息用于有线侧资源协商，所述VSNCP协议报文中封装有线接入网络控制面通道建链信令。
在步骤220中，根据所述VSP协议报文和VSNCP协议报文处理NAS信息及AS参数信息。
本实施例中，AGF接收UE发送的VSP协议报文和VSNCP协议报文，根据VSNCP协议报文中封装的建链信令建立有线接入网络控制面通道，以用于承载VSP协议报文的传输，从而接收NAS信息及AS参数信息，实现对NAS信息及AS参数信息的处理，例如确定与NAS信息对应的AMF，对NAS系统信息进行透传或转发等，从而为AMF对用户的注册认证提供可靠的NAS信息，实现用户的注册认证，又如，根据AS参数信息完成有线侧资源协商，从而为UE接入网络创建接入资源。
在一实施例中，接收VSP协议报文和VSNCP协议报文，包括：接收VSNCP报文并根据VSNCP协议报文建立有线接入网络控制面通道的链接；通过有线接入网络控制面通道接收VSP协议报文。
本实施例中，VSNCP是用于建立5G-RG到AGF之间的有线接入网络控制面通道的协议，基于有线接入网络控制面通道可以承载VSP协议报文的传输；VSP协议报文通过携带NAS信息及AS参数信息从而实现控制面的NAS信息传输。VSNCP协议报文在UE侧(5G-RG)封装完成后，可以发送建链请求信息到AGF，AGF回复或响应建链请求，根据VSNCP协议报文建立有线接入网络控制面通道的链接，在此基础上，AGF可以接收VSP协议报文传输的NAS信息及AS参数信息，并对NAS信息进行处理，将其进一步传输至AMF。
在一实施例中，所述VSNCP协议报文包括编码字段和数据字段，编码字段为第三设定值、第四设定值或第五设定值中的至少一种；根据VSNCP协议报文建立有线接入网络控制面通道的链接，包括以下至少之一：在编码字段为第三设定值的情况下，根据数据字段中的建链请求信息建立有线接入网络控制面通道的链接；在编码字段为第四设定值的情况下，向终端回复第四设定值对应的建链响应信息；在编码字段为第五设定值的情况下，向终端回复第五设定值对应的建链响应拒绝信息。
本实施例中，VSNCP协议报文在UE侧(即5G-RG)封装完成后发送到AGF，AGF根据编码字段和数据字段建立有线接入网络控制面通道或针对建链 请求信息进行回复。例如，对于编码字段为第三设定值(Code＝8)，则根据建链请求信息建立有线接入网络控制面通道；如果编码字段为第三设定值(Code＝8)的建链请求信息正常，AGF接收建链请求，则向UE回复编码字段为第四设定值(Code＝9)的建链响应信息；如果编码字段为第三设定值(Code＝8)的建链请求信息异常、AGF拒绝建链请求，则向UE回复编码字段为第五设定值(Code＝10)的建链响应拒绝信息。
例如，UE与AGF之间的建链过程可以为：
Step1，UE向AGF发送建链请求(Connection-Request)信息到AGF；
Step2，AGF收到建链请求信息后，向UE回复建链响应(Connection-Accept)信息，从而完成UE与AGF的控制面通道的建链。
或者，UE与AGF之间的建链过程可以为：
Step1，UE向AGF发送建链请求信息；Connection-Request到AGF。
Step2，AGF收到建链请求信息后，向UE回复建链响应拒绝信息(Connection-Reject)信息，告知UE控制面通道的建链请求被拒绝。
在一实施例中，VSP协议报文包括预留字段和数据字段；基于有线接入网络控制面通道和VSP协议报文向AMF传输所述NAS信息及AS参数信息，包括：在预留字段为第一设定值的情况下，将基于有线接入网络控制面通道接收的VSP协议报文中的数据字段中封装的NAS系统信息透传至核心网AMF；在预留字段为第二设定值的情况下，解析数据字段中封装的NAS定制信息，确定对应的AMF，并将对应的预留字段为第一设定值的NAS系统信息通过N2接口协议发送至对应的AMF；解析所述AS参数信息，并根据所述AS参数信息对有线侧网络资源进行协商解析；其中AMF用于认证用户注册请求。
本实施例中，VSP协议报文在UE侧(即5G-RG)封装完成后发送到AGF，AGF通过解析VSP协议报文的内容，处理其中携带的NAS信息。例如，在Reserved＝1的情况下，Data字段中封装了NAS系统信息，AGF将NAS系统信息透传转发至核心网AMF，AMF进行用户注册认证；在Reserved＝2的情况下，AGF对Data字段中的NAS定制信息进行解析，据此选取对应的AMF，例如，根据NAS定制信息中的Registered AMF确定对应的AMF，并将Reserved＝1的NAS系统信息通过N2接口协议完发送至对应AMF，在此基础上，5G核心网完成用户的接入认证及授权；在Reserved＝2的情况下，AGF还对Data字段中的AS参数信息进行解析，据此实现有线侧接入网络的资源协商，创建有线侧用户面资源。
上述实施例的信息处理方法适用于WWC技术场景，有线接入侧与无线接 入侧均通过NAS协议传输到5G核心网实现对用户的接入注册认证及授权，实现了有线侧对控制面协议中NAS信息的封装以及AGF对携带NAS信息的报文的处理。本实施例基于VSP协议和VSNCP协议扩展支持NAS信息及AS参数信息信息的传输，基于现网、固网网络通用的PPP协议传输的应用背景，为厂商实现以及标准规范制定提供了有效可靠的依据。

在步骤307中，解析所述数据字段中封装的AS参数信息，根据所述AS参数信息进行有线侧资源协商。

在步骤309中，VSNCP协议报文编码字段是否为第四设定值？若是，则执行步骤310，否则执行步骤311。
在步骤310中，向终端回复第四设定值对应的建链响应信息。
在步骤311中，VSNCP协议报文编码字段是否为第五设定值？若是，则执行步骤312，否则返回执行步骤301，继续接收NAS信息。
在步骤312中，向终端回复第五设定值对应的建链响应拒绝信息。
本实施例中，对于VSNCP协议报文，编码字段已扩展为第三设定值、第四设定值或第五设定值，对于其他取值都会反馈Code-Reject。
在一实施例中，AGF对于NAS信息及AS参数信息的处理，也可以只通过扩展OUI字段实现，这种情况下，VSNCP协议中的OUI字段如果为第一标识(OUI-X)，则VSNCP协议报文用于承载NAS系统信息，如果OUI字段为第二标识(OUI-Y)，则VSNCP协议报文用于承载NAS定制信息及AS参数信息。VSNCP协议的编码字段依然复用原LCP协议字段。在进行VSNCP控制面通道建链的过程中，5G-RG侧发送VSNCP协议报文编码字段值为1的Configure-Request报文到AGF，AGF回复VSNCP协议报文编码字段值为2的Configure-ACK报文到5G-RG，VSNCP控制面通道建链成功；如果AGF对收到的所述VSNCP协议报文编码字段值为1的Configure-Request报文处理异常，回复VSNCP协议报文编码字段值为3的Configure-Reject报文到5G-RG，VSNCP控制面通道建链拒绝。
本实施例的信息处理方法，AGF通过VSP协议报文或VSNCP协议报文建立有线接入网络控制面通道并对NAS信息及AS参数信息进行处理，包括将NAS系统信息透传至AMF、选取对应的AMF，为AMF对用户的注册认证提供可靠信息，及通过传输AS参数信息实现有线侧资源协商。
