Description

通信方法和装置
本申请要求于2018年1月12日提交中国专利局、申请号为201810032695.X、申请名称为“通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种通信方法和装置。
背景技术
近年来，全球宽带接入网络建设大力发展，宽带普及率不断增长。当前的家庭宽带接入(也称为室内宽带接入)技术，以固定(有线)宽带接入(Fixed Broad Band，FBB)为主，无线宽带(Wireless Broad Band，WBB)接入或无线到x(Wireless to the X，WTTx)接入为辅。
图1为现有的一种家庭宽带接入网络的示意图，如图1所示，用户设备(User Equipment，UE)通过有线或无线局域接入链路与用户驻地设备(Customer Premiese Equipment，CPE)/家庭网关(residential Gateway，RG)建立连接，CPE/RG再通过有线或无线宽带接入链路与宽带接入网络设备连接，宽带接入网络设备与核心网设备连接。现有技术中，CPR或RG可以为一个中继用户设备(User Equipment，UE)，该中继UE(relay UE)可以作为一个远端UE(remote UE)接入无线网络的中继点，远端UE和中继UE之间建立设备到设备(Device 2 Device，D2D)连接，D2D连接可以采用第三代伙伴计划(The 3rd Generation Partnership Project，3GPP)定义的PC5接口进行通信，也可以采用蓝牙、WiFi、Zigbee等短距离无线通信协议进行通信。中继UE和无线接入网(Radio access network，RAN)设备之间建立无线链路进行通信，例如长期演进计划(Long Term Evolution，LTE)/演进的通用陆地无线接入E-UTRA(Evolved Universal Terrestrial Radio Access)系统的空口链路。
但是，上述现有技术中，relay UE和remote UE之间的D2D链路无法为remote UE的业务提供有效的QoS保障，且上述方法的中继UE只能通过空口(即Uu接口)接入到无线接入网设备，没有考虑CPE/RG通过固定宽带接入方式接入网络的场景。若UE在室内通过固定宽带接入方式接入固定宽带网络，在室外通常通过无线空口接入到无线网络，当UE在室内和室外之间移动时，常常会导致UE的连接断开，业务不连续。现有的固定宽带接入网络中，常采用尽力而为(best effort)服务质量(Quality of Service，QoS)策略，会导致UE的QoS难以保证。

具体实施方式
本申请提供一种UE的通信方法，图2为本申请适用的一种网络架构的示意图，如图2所示，该网络架构包括：UE侧、(无线)接入网((Radio)Access Network，(R)AN)和核心网(Core Network，CN)。其中，UE侧包括UE、CPE或家庭网关(residential gateway，RG)，UE通过无线接入链路，如基于无线局域网WLAN、蓝牙、Zigbee等各类技术协议的链路，或基于第三代合作伙伴计划(3GPP)组织制定的无线接入技术标准如NR、LTE等制式中的空口链路(包括Uu接口、PC5接口等)，或有线接入链路(如有线LAN链路)连接到CPE/RG，CPE/RG可以是光调制解调器(Optical modem，也称为光猫)、无线路由器等。需要说明的是，CPE/RG可以被视为UE侧设备，也可以被视为接入网侧设备，即将CPE看做一个接入网设备，例如，CPE/RG作为一个家庭接入点(home access point，hAP)，或者中继节点(relay node，RN)，为终端设备提供接入服务。本申请中，为了表述便利，下文将主要以CPE为例来进行介绍。
接入网侧包括宽带接入设备、移动接入网设备和家庭接入网关(home access  gateway，HA GW)。宽带接入设备包括有线接入网(access network，AN)设备和移动接入网设备，有线接入网设备例如是数字用户线路接入复用器(Digital Subscriber Line Access Multiplexer，DSLAM)。移动接入网设备可以是LTE系统中的演进型基站(evolved NodeB，eNB)、AP或者中继站，也可以是第五代移动通信(5 Generation，5G)系统中的无线接入网(radio access network，RAN)设备，5G系统中的RAN设备可以由多个5G-RAN节点组成，该5G-RAN节点可以为：AP、下一代基站(可统称为新一代无线接入网节点(NG-RAN node)，包括新空口基站(NR nodeB，gNB)、新一代演进型基站(NG-eNB)、中心单元(central unit，CU)和分布式单元(distributed unit，DU)分离形态的gNB等)、收发点(transmission receive point，TRP)、传输点(transmission point，TP)或其它节点。5G系统也称为新无线通信系统、新接入技术(New Radio)或者下一代移动通信系统。移动接入网设备还可以是GSM系统或CDMA系统的基站(Base Transceiver Station，BTS)，或者宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)。图2所示例子中共有两种UE，一种UE(例如UE1和UE2)通过CPE与家庭宽带接入设备连接，其中，CPE与家庭宽带接入设备可以通过有线宽带接入链路或无线宽带接入链路连接；另一种UE(例如UE3)直接与移动接入网设备连接。家庭宽带接入设备连接和移动接入网设备均可以与家庭接入网关连接，通过家庭接入网关连接到核心网设备，移动接入网设备还可以直接连接到核心网设备。
家庭接入网关也称为家庭接入中心单元(home access central unit，HA CU)，家庭接入网关为UE提供连接管理服务，其与核心网设备之间的链路称为回传链路，家庭宽带接入设备可以连接到家庭接入网关上，或者，两者为同一个物理设备；类似的，移动接入网设备也可以与家庭接入网关之间建立连接，或者，两者为同一个物理设备。
本申请中核心网可以是LTE系统的核心网，即演进分组核心网(evolved packet core，EPC)，也可以是5G系统的核心网(5G core/new generation core，5GC/NGC)。图3为5G核心网的一种示意图，5G核心网包括接入和移动性管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户面功能(User Plane Function，UPF)、鉴权服务器功能(Authentication Server Function，AUSF)、策略控制功能(Policy Control Function，PCF)等多个功能单元。

步骤S101、CPE向家庭接入网关发送第一请求消息。
该第一请求消息用于请求建立第一连接，第一连接为CPE与家庭接入网关之间的连接。CPE和家庭接入网关之间的第一连接为承载于第一链路之上的逻辑连接，该第一连接例如是F1连接，或类F1(F1-like)连接，或者F1’连接，还可以是其他名称，可用于对CPE和其服务的小区进行配置管理以及对CPE服务的终端设备的上下文信息进行管理，或者该第一连接还可以是CPE和家庭接入网关之间的RRC连接，本申请实施例中将主要以第一连接为F1连接为例进行介绍，但对第一连接的类型和具体命名方式不予限定。
该第一请求消息中包括CPE的标识，一个家庭接入网关，可以管理多个CPE，第一请求消息中携带CPE的标识是为了告知家庭接入网关哪个CPE请求建立连接。可选的，第一请求消息中还包括CPE服务的小区信息。
本申请中，CPE是指通过有线/无线链路连接到AN/RAN设备，并且为UE提供接入链路，使UE可以经由CPE接入网络的设备。本申请中的CPE可以是有线宽带接入 中的用户驻地设备或家庭网关，可以被视做是UE(对于网络侧而言)，也可以被视为是一个网络设备，比如家庭接入点，或者中继节点(relay node，RN)。例如，当CPE为无线RN的时候，RN通过无线回传连接到网络设备1(中继的父节点，可以是另一个RN，或者是宿主基站Donor gNB)，并且通过无线接入链路为UE提供网络接入服务。
可选的，该CPE的标识可以包括但不限于CPE的互联网协议(Internet Protocol，IP)地址、媒介接入控制(medium access control，MAC)地址、链路层标识(Link Layer ID)、小区无线网络临时标识(cell radio network temporary identity，C-RNTI)、国际移动用户标识(international mobile subscriber identity，IMSI)、国际移动台设备标识(international mobile station equipment identity，IMEI)、临时移动用户标识(temporary mobile subscriber identity，TMSI)、小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)、Prose UE ID、RAN设备或核心网设备在特定接口上(例如gNB与AMF之间的N2接口、eNB与MME之间的S1接口、gNB-DU与gNB-CU之间的F1接口)上为CPE分配的UE标识(例如AMF UE NGAP ID，gNB UE NGAP ID，eNB UE S1AP ID，MME UE S1AP ID，gNB-DU UE F1AP ID，gNB-CU UE F1AP ID)、人为设置的可读的CPE名称等，本申请中不予限定。
可选的，CPE服务的小区信息可以包括以下信息中的至少一项：CPE服务的小区标识、跟踪区域信息(包括跟踪区域码字(Tracking area code，TAC)以及跟踪区域标识(Tracking area identity,TAI)等)、PLMN的信息、天线端口信息、物理随机接入信道(Physical Random Access Channel，PRACH)配置信息、CPE服务小区的系统信息等。
其中，CPE服务的小区标识可以为WLAN中的标识，例如基本服务集标识(Basic Service Set Identifier，BSSID)、服务集标识(Service Set Identifier，SSID)、同类扩展业务集标识(homogenous extended service set identifier，HESSID)等；CPE服务的小区标识还可以是移动网络中常用的小区标识，例如演进型-通用移动通信系统陆地无线接入网小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)、物理小区标识(Physical cell Identity，PCI)、新空口小区全局标识(NR Cell Global Identity，NCGI)、局部唯一的(local)小区标识(cell ID)、等，本申请中对于小区标识的形式不予限定。
可选的，CPE在向家庭接入网关发送第一请求消息之前，需预先获取家庭接入网关的传输地址(例如家庭接入网关的IP地址)，获取方式可以是预配置在CPE中，或者包含在UE策略(UE policy)中，由PCF经AMF和AN/RAN设备发送给CPE。一种可能的方式中，CPE预先获取的家庭接入网关传输地址为默认(default)家庭接入网关的地址，所述默认家庭接入网关在收到CPE的第一请求消息后，可以选择更合适的家庭接入网关(例如根据CPE的位置信息，选择离CPE更近的家庭接入网关)然后将选择的家庭接入网关地址发送给CPE，CPE将再执行步骤S101，向所述更合适的家庭接入网关发送第一请求。
本申请实施例中，第一链路为CPE和家庭接入网关之间的链路，第二链路为UE和CPE之间的链路。第一链路也称为回传链路(Backhaul Link，BL)，第二链路也称 为接入链路(Acess Link，AL)，本申请中第一链路和回传链路可以互换，第二链路和接入链路也可以互换。
可选的，第一链路为第一类链路或第二类链路，第二链路也可以为第一类链路或第二类链路，第一类链路为基于3GPP连接的链路，或者称为3GPP制式的链路(下文中将简称为“3GPP链路”)，第二类链路为基于非3GPP连接的链路，也称为非3GPP制式的链路(下文中将简称为“非3GPP链路”)。其中，该基于3GPP连接的链路，是指基于3GPP组织制定的移动通信标准所对应的无线接入技术(Radio Access Technology，RAT)中的空口链路，例如是LTE、LTE-U、NR、UMTS、GSM等通信技术中的空口链路，还可以是终端直连通信对应的PC5接口链路等。该基于非3GPP连接的链路，是指除上述3GPP组织制定的移动通信标准所对应的RAT中的空口链路之外，其他通信标准所对应的接入技术中的通信链路，例如是WLAN、Bluetooth、Zigbee、Ethernet、PPP、PPPoE、ATM、CDMA、CDMA2000等标准中涉及的无线或有线通信链路。
可选的，触发CPE与家庭接入网关建立第一连接的方式可以包括以下几种：
(1)CPE根据预先获取的第一配置信息，向家庭接入网关发送第一请求消息，该第一配置信息用于触发建立第一连接。该第一配置信息可以包含在发送给CPE的UE策略(UE Policy)中，由PCF通过AMF发送至CPE，或者通过CPE的管理服务器(如TR-069服务器)发送配置信息携带给CPE，或者静态配置在CPE中。
(2)当CPE通过第二链路接收到UE发送的表明UE有连接到家庭接入网关需求的信息时，向家庭接入网关发送第一请求消息。所述表明UE有连接到家庭接入网关需求的信息，例如是UE的类型为移动网络终端。需要明确的是，本申请中不对第一连接和第二链路的建立顺序做限定，第一连接可以在第二链路建立之后建立，也可以先于第二链路建立，因此，示例性的，UE可以在与CPE建立第二链路的过程中或者在第二链路建立完成后，将表明UE的类型的信息发送给CPE，CPE根据UE的类型，确定是否建立第一连接。
(3)当CPE接收UE发送的特定标记报文时，CPE向家庭接入网关发送第一请求消息。例如UE向网络发RRC连接请求消息时，在发给CPE的报文中添加该特定标记，CPE首次收到包含特定标记的报文时，向家庭接入网关发送第一请求消息。
步骤S102、家庭接入网关向CPE发送第一响应消息，该第一响应消息中包括家庭接入网关的标识和需要激活的小区标识信息。
该需要激活的小区属于CPE服务的小区，CPE服务的小区列表可以是CPE通过第一请求消息发送给家庭接入网关的，也可以是预先配置在家庭接入网关中的，其中，需要激活的小区为CPE服务的小区的子集。若CPE服务的小区列表是预配置在家庭接入网关中的，则家庭接入网关接收到第一请求消息后，根据第一请求消息中包括的CPE的标识，找到CPE服务的小区信息，然后确定需要激活的小区标识。
步骤S103、UE发现CPE，并与CPE建立第二链路。
示例性的，CPE向UE发送发现信号，该发现信号用于UE发现CPE。其中，CPE发送发现信号的方式，视CPE与UE之间的连接方式而定，例如，当CPE采用3GPP制式(例如LTE，或者NR，或者LTE-U，或者NR-U，“-U”表示采用unlicensed频 谱)的接入技术为UE服务时，CPE发送系统广播消息，UE通过接收系统广播发现CPE服务的小区。当CPE采用非3GPP制式的接入技术为UE服务时，例如，CPE与UE之间建立WLAN连接，则CPE发送信标(beacon)消息，UE通过接收beacon消息发现CPE服务的小区；或者，CPE与UE之间建立终端直连通信(device to device，D2D)链路(sidelink)，CPE可以发送discover信号(model A)或solicitation信号(model B)，与UE之间相互发现。具体地，涉及各个制式接入技术的具体发现过程及连接建立过程可以参考现有技术。例如，若UE与CPE之间的链路为3GPP链路，则UE发起随机接入，与CPE建立连接，UE与CPE建立非3GPP链路的过程可参考现有技术。
可选的，本申请中，CPE发送的发现信号中包括第一指示信息，该第一指示信息用于指示所述CPE支持为UE提供到第一类网络的连接，以及支持为UE提供到第一类网络中的移动性管理和QoS管理等功能，以使得UE优先选择通过该CPE接入网络。该第一类网络例如是3GPP制式的接入网RAN和/或核心网(如EPC/5GC))，3GPP制式的网络包括LTE系统、LTE-U系统、NR、UMTS系统和GSM系统中的任一种。
需要明确是，UE发现CPE的过程中，可能包括多条消息，图4中只是一个示意图，并不表示发现过程和第二链路的建立过程只有一条消息。所述第一指示信息还可以配置在UE中，例如静态配置在UE的SIM卡中，或者由特定服务器通过配置信息发送给UE。
步骤S104、UE向家庭接入网关发送第二连接建立请求。
UE通过CPE向家庭接入网关发送第二连接建立请求，第二连接建立请求用于请求建立第二连接，第二连接为UE与家庭接入网关之间的连接，第二连接是承载于第一链路和第二链路之上的逻辑连接。示例性的，第二连接建立请求为RRC连接建立请求，UE先向CPE发送RRC连接建立请求，然后CPE向家庭接入网关发送包含UE的RRC连接建立请求的RRC传输消息(RRC message transfer)，其中，RRC连接建立请求可以通过RRC消息容器携带在RRC传输消息中。可选的，所述RRC传输消息为第一连接应用消息(如第一连接被命名为F1连接时，则所述第一连接应用消息为F1AP消息)，其具体类型可以为初始上行RRC传输消息(initial UL RRC message transfer)。
CPE在发送给家庭接入网关的初始上行RRC传输消息(即包含UE的RRC连接请求的RRC传输消息)中，包含UE的RRC连接建立请求，还可以包含以下UE的标识和/或UE所在小区的标识。
其中，UE的标识包括：UE在CPE和家庭接入网关之间第一连接上的标识，以及UE在小区中的标识。UE在CPE和家庭接入网关之间第一连接上的标识，包括以下中的至少一项：UE在CPE和家庭接入网关之间第一连接上的标识1，即CPE UE F1AP ID(由CPE分配给UE，用于在CPE服务的UE中唯一标识一个UE，或者也可称为home AP/DU UE F1AP ID)，以及UE在CPE和HA GW之间第一连接上的标识2，即HA GW UE F1AP ID(由HA GW分配给UE，在HA GW服务的UE中唯一标识一个UE，或者也可称为home-CU UE F1AP ID)。例如本步骤中，CPE发往家庭接入网关的包含UE的RRC连接请求的RRC传输消息中，包含的UE的标识可以是CPE UE F1AP ID。
UE在小区中的标识可以包括但不限于以下中的至少一项：UE的C-RNTI，MAC地址，IP地址，物理接口标识(例如CPE与UE通过有线接口连接)，虚拟局域网(Virtual  Local Access Network，VLAN)ID(若划分了不同的VLAN)等。
UE所在小区的标识的内容可参考步骤S101中对“CPE服务的小区标识”的描述进行理解，不予赘述。
值得注意的是，如果UE与CPE之间的链路为非3GPP链路，UE发送至CPE的数据包，需要携带第二指示信息，该第二指示信息用于指示数据包中的内容为控制面信令或者用户面数据，或者该第二指示信息用于指示数据包对应的无线承载标识。例如，UE在对数据包进行链路层封装之前，在数据包中添加第二指示信息。这是因为在非3GPP链路中，没有承载和逻辑信道的概念，故CPE无法通过承载数据包的无线承载或逻辑信道区分数据包的内容为控制面信令还是用户面数据，由于CPE对于UE的用户面数据和控制面信令的处理协议层不同，为使CPE能将UE的数据包递交给合适的协议层进行处理，故需要携带第二指示信息以区分两种数据包。可选的，该第二指示信息携带在UE和CPE之间接口上新增的适配协议层中，或者携带在UE和CPE之间接口上的任意现有协议层中。
具体的，该第二指示信息可以为一个数据类型字段，当数据类型字段的取值为某一特定值或某一组特定值时，表示数据包中的内容为控制面信令，当数据类型字段的取值为另一特定值或另一组特定值时，则表示数据包中的内容为用户面数据。或者，该第二指示信息可以为UE的信令无线承载(Signaling Radio Bearer，SRB)标识(ID)或数据无线承载(Data Radio Bearer，DRB)ID。
类似地，CPE发往HA GW的数据包中，也可以包含第二指示信息，以便HA GW将UE的数据包递交给合适的协议层进行处理。
当CPE和HA GW之间的第一连接为F1连接时，可选的，CPE向HA GW发送的包含第一连接应用消息的数据包中，还可以包含第三指示信息，所述第三指示信息用于指示所述数据包为控制面信令或用户面数据，进一步的，还可以指示所述控制面数据包中的内容为CPE的RRC消息或者是F1连接应用消息。
当CPE和HA GW之间的第一连接为F1连接时，CPE向HA GW发送的包含第一连接应用消息的数据包中可以只包含第三指示消息，而不包含第二指示消息。
步骤S105、家庭接入网关向UE发送RRC连接建立消息。
家庭接入网关需要通过CPE将该RRC连接建立消息发送给UE，示例性的，家庭接入网关先向CPE发送第一连接应用消息(如F1AP消息)，其中包括RRC连接建立消息、UE的标识和SRB ID。所述第一连接应用消息的类型例如为下行RRC传输消息(DL RRC message transfer)。
所述UE的标识的内容可以参考步骤S104中的相应描述进行理解。
可选的，所述第一连接应用消息中还包括以下信息中的至少一项：UE所在小区的标识、用于表明消息类型为RRC消息的指示信息。CPE收到所述第一连接应用消息后，可以将其中的RRC连接建立消息通过由所述SRB ID所标识的SRB发送至与UE的标识对应的UE。若CPE与UE之间的第二链路为非3GPP链路，则CPE在将发送至UE的RRC连接建立消息进行链路层封装之前，需要添加第二指示信息。其中，本步骤中，家庭接入网关向CPE发送的F1AP消息中，UE的标识可以为HA GW UE F1AP ID，而本步骤中涉及的第二指示信息以及UE所在小区的标识的具体描述参照步骤S104中 的相关描述，这里不再赘述。
可选的，家庭接入网关发送给CPE的第一连接应用消息中，包含RRC消息容器，RRC连接建立消息携带在RRC消息容器中。
步骤S106、UE向家庭接入网关发送RRC连接建立完成消息。
可选的，该RRC连接建立完成消息先由UE发送至CPE，再由CPE携带在第一连接应用消息中向家庭接入网关发送。所述第一连接应用消息的类型可以为例如上行RRC传输消息(UL RRC message transfer)。
其中，第一连接应用消息中，包含UE的标识、RRC连接建立完成消息和SRB ID。可选的，第一连接应用消息中还可以包含UE所在小区的标识和/或用于表明消息类型为上行RRC消息的指示信息。
家庭接入网关接收到UE的RRC连接建立完成消息后，意味着家庭接入网关与UE之间的RRC连接建立完成。之后家庭接入网关可以与UE之间经由CPE发送上行和下行的RRC消息。
对于UE的上行RRC消息，若UE与CPE之间采用非3GPP制式的连接，则UE可在封装RRC消息的报文中添加第二指示信息，例如在适配层报文头中添加第二指示信息，CPE读取第二指示信息，获知该消息类型为UE的RRC消息，或者进一步获知承载该RRC消息的SRB ID；若CPE与UE之间的链路为3GPP链路，则UE与CPE之间的逻辑信道与UE的无线承载一一对应，其中，无线承载包括SRB和DRB。CPE可以根据收到RRC消息的逻辑信道确定接收到的消息为RRC消息以及对应的SRB ID。然后CPE可以将UE的上行RRC消息携带在第一连接应用消息中向HA GW发送，当CPE和HA GW之间的第一连接为F1连接时，可选的，CPE向HA GW发送的包含第一连接应用消息的数据包中，还可以包含第三指示信息，所述第三指示信息用于指示所述数据包为控制面信令或用户面数据，进一步的，还可以指示所述数据包中的内容为CPE的RRC消息或者是F1连接应用消息。当CPE和HA GW之间的第一连接为F1连接时，CPE向HA GW发送的包含第一连接应用消息的数据包中可以只包含第三指示消息，而不包含第二指示消息。
对于HA GW生成的发送给UE的下行RRC消息，HA GW将其携带在第一连接应用消息中发送给CPE，CPE收到所述第一连接应用消息后，再将其中包含的给UE的RRC消息发送给UE。可选的，若在所述第一连接应用消息中包含SRB ID，则CPE可以将所述RRC消息通过与所述SRB ID指示的SRB发送给UE，或者通过与所述SRB对应的逻辑信道发送给UE。若CPE与UE之间的链路为非3GPP链路，则CPE在发送给UE的包含下行RRC消息的数据包中，添加第二指示信息，用于指示消息类型为UE的RRC消息，还可进一步指示所述消息对应的SRB ID，所述第二指示信息，可以在UE和CPE之间接口上新增的适配层处理过程中添加(例如添加在适配层报文头中)，或者在任意已有的协议层处理过程中添加(例如添加在已有协议层对应的报文头中)。当CPE和HA GW之间的第一连接为F1连接时，可选的，HA GW向CPE发送的包含第一连接应用消息的数据包中，还可以包含第三指示信息，所述第三指示信息用于指示所述数据包为控制面信令或用户面数据，进一步的，还可以指示所述数据包中的内容为发送给CPE的RRC消息或者是F1连接应用消息。当CPE和HA GW之间的第一 连接为F1连接时，HA GW向CPE发送的包含第一连接应用消息的数据包中可以只包含第三指示消息，而不包含第二指示消息。
步骤S107、家庭接入网关向核心网网元发送第二请求消息。
在该第二请求消息中，可以包含UE的会话建立请求消息，该会话建立请求消息用于请求建立分组数据单元(packet data unit，PDU)会话(Session)，该会话建立请求消息可以为非接入层(Non-access stratum，NAS)消息，UE将该会话建立请求消息携带在上行RRC消息中通过CPE发送至家庭接入网关，家庭接入网关将该会话建立请求消息发送至核心网网元(例如AMF)。可选的，该第二请求消息中还可以包含UE的注册请求，用于向网络发起注册。该第二请求消息可以是NGAP消息，例如初始UE信息(initial UE message)或其他类型的NGAP消息。
S108、UE和网络之间进行鉴权认证。
UE可以与例如AUSF、UDM等核心网网元进行鉴权认证完成注册过程，或与数据网络(data network，DN)中具有认证鉴权功能的设备(比如AAA server)之间进行交互完成鉴权，鉴权过程中会有多条信令交互，鉴权过程参照现有技术，这里不再赘述。鉴权过程中CPE和家庭接入网关作为中间传输点，传输鉴权过程中涉及到的消息。
步骤S109、会话建立过程。
AMF收到UE的会话建立请求消息后，与其他核心网元(例如PCF、UPF、UDM等)进行交互，完成PDU会话的建立，会话建立过程中，家庭接入网关接收AMF发送的初始上下文建立消息，初始上下文建立消息中包含UE的上下文信息，例如包含以下信息中的至少一项：与UE的PDU session对应的N2接口会话管理信息，以及给UE的NAS消息；该与UE的PDU session对应的N2接口会话管理信息包含CN tunnel info，QoS流(flow)相应的配置信息(如QoS profiles以及QoS flow标识等)，PDU session ID等。该给UE的NAS消息将由家庭接入网关携带在给UE的下行RRC消息然后经CPE发送至UE。具体的会话建立过程可参考现有技术，这里不再赘述。

场景四：第一链路为第二类链路，第二链路为第一类链路。

本申请中需要定义家庭接入网关与UE之间的两段连接协议栈架构，家庭接入网关与UE之间的协议架构有图5和图6所示两种选项，其中，图5为一种用户面协议架构的示意图，对应于CPE和家庭接入网关之间的第一链路采用通用分组无线服务(General Packet Radio Service，GPRS)隧道协议(GTP)隧道的链路，图6为另一种用户面协议架构的示意图，在CPE和家庭接入网关之间的第一链路采用基于适配层(Adaption，以下简称Adapt.)的链路。
参照图5，UE的协议栈从高到低依次为：业务数据适配协议(Service Data  Adaptation Protocol，SDAP)层、分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、面向第二链路的适配(Adapt.)协议层、面向第二链路的链路层(Layer 2，L2)和面向第二链路的物理层(Layer 1，L1)。CPE在与UE之间的第二链路对应接口上的协议栈从高到低依次为：面向第二链路的Adapt层、面向第二链路的L2和面向第二链路的L1，CPE在与家庭接入网关之间的第一链路对应接口上的协议栈从高到低依次为：与家庭接入网关对等的GTP层、用户面数据报协议(User Datagram Protocol，UDP)层、IP层，以及面向第一链路的链路层(L2)、面向第一链路的物理层(L1)。家庭接入网关在面向第一链路对应接口上的协议栈从高到低依次为：与UE对等的SDAP层、PDCP层，与CPE对等的GTP层、UDP层、IP层，以及面向第一链路的链路层L2、面向第一链路的物理层L1。
所述链路层L2和物理层L1对应的具体协议层，可以视第一链路和第二链路所基于的通信技术协议而定，对L1和L2包含的具体协议层，本申请实施例中不予限定。譬如，当第一/二链路为基于LTE/NR的3GPP链路时，L2包括例如无线链路控制(Radio Link Control，RLC)层和MAC层，物理层L1即PHY层，这些协议层的功能可参考LTE/NR技术规范中对这些协议层的具体描述，不予赘述。又如，当第一/二链路为非3GPP链路时，L2可以包括例如逻辑链路控制(Logical Link Control，LLC)层、MAC层、以太网(Ethernet)层、点对点协议(Point to Point Protocol，PPP)层、以太网上的点对点协议层(PPPoE，Point to Point Protocol over Ethernet)等中的至少一种。
在UE和CPE之间的第二链路上，对于发送端而言(上行方向发送端为UE，下行方向发送端为CPE)，面向第二链路的适配层(Adapt.)的功能包括添加适配信息。所述适配信息包含UE的无线承载的信息(例如添加无线承载标识，即SRB ID或DRB ID)，可选的，所述适配信息还包含以下信息中的任至少一种：UE的标识、第二指示信息、第三指示信息。对于第二链路的接收端而言(上行方向接收端为CPE，下行方向接收端为UE)，通过读取发送端在适配层中携带的适配信息，确定具体是哪一个UE，以及数据包对应的UE的承载的信息。需要说明的是，在第二链路的通信对端上配置适配层为可选项，所述适配层的功能也可以通过其他现有协议层实现，例如在现有的链路层L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)或者物理层L1中添加所述适配信息；或者，如果第二链路是第一类链路，则可无需Adapt层，第二链路的接收端可以根据UE的C-RNTI确定UE，并根据接收数据包的逻辑信道，确定与所述逻辑信道对应的UE的无线承载。
基于图5所示的用户面协议栈，在第一链路上，基于第一连接，CPE和家庭接入网关之间将建立与UE的DRB一一对应的GTP隧道，通过GTP隧道的TEID，可以确定UE以及UE的DRB。相应地，UE的下行数据包的处理如下：家庭接入网关在执行SDAP层的处理(例如添加服务质量流标识(QoS flow identity，QFI)，进行QoS流到UE的DRB的映射等)、PDCP层的处理后，依次进行GTP层的处理(例如添加CPE为与UE的DRB对应的GTP隧道分配的下行TEID)，以及UDP、IP层的处理，并执行适配处理。所述适配处理包括QoS映射处理，和/或适配信息的添加。其中，家庭接入网关对SDAP层和PDCP层的处理可以参照现有技术，这里不再赘述。
所述QoS映射处理，例如是：当第一链路为第一类链路时，家庭接入网关执行从 UE QoS flow到CPE的无线承载的映射，或者执行从UE的无线承载到CPE的无线承载的映射。当第一链路为第二类链路时，家庭接入网关执行从UE QoS flow到第一QoS标识的映射，或者，执行UE的无线承载到第一QoS标识的映射。具体映射过程参照上述实施例中的相关描述，这里不再赘述。所述适配信息的添加，包括添加以下信息中的至少一项：第一QoS标识、第二指示信息、第三指示信息。然后，家庭接入网关将数据包进行面向第一链路的链路层L2的处理，再递交至面向第一链路的物理层L1处理，并通过第一链路向CPE发送数据包。可选的，所述适配处理中的部分或全部过程可以是在以下任一协议层或任意多个协议层的处理中执行：面向第一链路的适配层、面向第一链路的L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)、面向第一链路的L1。所述面向第一链路的适配层可位于L2之上(例如在IP层和L2之间)，在图5中并未示出。
CPE接收到来自家庭接入网关的下行数据包，经过其接收侧包含协议栈(即CPE与HA GW之间的接口的协议栈)的逐层处理后得到UE的PDCP PDU，并根据GTP层的头部信息(如TEID)确定与数据包对应的UE以及UE的无线承载，可选的，若GTP头部信息中还包含UE的QoS flow的信息，则CPE还可以获知数据包对应的UE的QoS flow，然后将UE的PDCP PDU交由CPE的发送侧处理。CPE的发送侧的处理包括例如：当CPE与UE之间的第二链路为第一类链路时，CPE将UE的下行数据包通过UE的无线承载发送至UE，无需额外添加适配信息，即UE的PDCP PDU将经过依次RLC、MAC、PHY层的处理后被发送至UE，所述RLC、MAC、PHY层的处理过程可参考现有技术。当CPE与UE之间的第二链路为第二类链路时，CPE将对下行数据包进行适配处理：CPE将在下行数据包中添加适配信息(例如添加在适配层的头部中，或者添加在第二链路的任意现有协议层的头部中)，然后，CPE根据家庭接入网关发送的第一链路的配置信息和/或第二链路的配置信息，执行UE QoS flow到第二链路的第二QoS标识的映射，或者，执行UE的无线承载到第二链路的第二QoS标识的映射，或者，执行第一链路的第一QoS标识到第二链路的第二QoS标识的映射，具体映射过程参照上述实施例中的相关描述，这里不再赘述。可选的，CPE对下行数据包进行适配处理还包括：在面向第二链路的适配层或面向第二链路的链路层的处理中携带所述第二QoS标识。CPE执行的适配处理可以在面向第二链路的新增适配层执行，也可以在面向第二链路的链路层(L2)执行。
CPE将经过面向第二链路的链路层和物理层发送处理后的数据包发送至UE，UE接收数据包后，对数据包进行物理层和链路层的接收处理，然后根据数据包的逻辑信道(当第二链路为第一类链路时)确定数据包对应的UE的无线承载，或者，根据数据包中携带的UE的无线承载的标识确定数据包对应的UE的无线承载，将数据包传递给UE无线承载对应的PDCP实体(entity)进行PDCP层接收处理，继而进行SDAP层的接收处理。PDCP层和SDAP层的处理过程可参考现有技术，这里不再赘述。
对应于图5所示的协议架构，UE的上行数据包的处理和发送例如是：
若第二链路为第一类链路，则UE对上行数据包的处理过程，可参考现有技术中的相应描述，例如第一链路为基于NR的空口链路，则UE将对数据包依次执行SDAP层、PDCP层、RLC层、MAC层、PHY层的处理，然后在确定的UE的无线承载上向 CPE发送所述处理后的上行数据包，具体涉及各个协议层的处理过程可参考现有技术，不再赘述。UE确定用于发送上行数据包的UE的无线承载过程也可参考现有技术，例如在SDAP层执行从UE QoS flow到UE的无线承载的映射。
若第二链路为第二类链路，则UE将对数据包执行SDAP层、PDCP层的处理，并执行适配处理，以及面向第二链路的链路层处理后，再递交至面向第二链路的物理层(Physical，PHY)处理，并通过第二链路向CPE发送数据包。所述适配处理，包括QoS映射处理，和/或适配信息的添加。所述QoS映射处理，包括以下中的至少一项处理：从UE QoS flow到第二QoS标识的映射，从UE的无线承载到第二QoS标识的映射，从UE QoS flow到UE的无线承载的映射。具体映射过程参照上述实施例中的相关描述，这里不再赘述。所述适配信息的添加，包括添加以下标识中的至少一项：UE的QoS flow标识，UE的无线承载标识，第二QoS flow标识、第二指示信息和第三指示信息。可选的，所述适配处理中的部分或全部过程可以是在以下任一协议层或任意多个协议层的处理中执行：面向第二链路的适配层、SDAP层、PDCP层、面向第二链路的L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)、面向第二链路的L1。例如，UE可以在SDAP层添加QoS flow的标识，执行从UE的QoS flow到UE的无线承载的映射；在面向第二链路的适配层，添加UE的无线承载标识，执行从UE的无线承载到第二QoS标识的映射；在面向第二链路的链路层添加第二QoS标识等。可选的，若上述适配处理中的部分或全部过程由UE在面向第二链路的L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)和/或面向第二链路的L1执行，需要对第二链路实际使用的传输技术的L2和/或L1的功能进行扩展。
CPE接收UE发送的上行数据包，经过其接收侧包含协议栈(即面向CPE与UE之间的第二链路的协议栈)的逐层处理后得到UE的PDCP PDU。在逐层处理过程中，CPE可根据接收数据包的逻辑信道，或者数据包中携带的UE的无线承载的标识(例如携带在适配层头部)，确定数据包对应的UE的无线承载，可选的，若所述数据包还携带UE的QoS flow的标识(例如携带在适配层头部)，则CPE还可确定数据包的QoS flow。CPE将所述UE的PDCP PDU再依次进行GTP层的处理(例如添加HA GW为与UE DRB对应的GTP隧道分配的上行TEID)，以及UDP、IP层的处理，然后CPE对数据包执行QoS映射处理，以及面向第一链路的链路层处理，和面向第一链路的物理层处理，并通过第一链路向家庭接入网关发送数据包。所述QoS映射处理可以包括但不限于：当第一链路为第一类链路时，CPE执行从UE QoS flow或UE的无线承载或第二QoS标识到CPE DRB的映射；当第一链路为第二类链路时，CPE执行从UE QoS flow或UE的无线承载或第二QoS标识到第一QoS标识的映射。具体QoS映射处理过程参照上述实施例中的相关描述，这里不再赘述。可选的，所述QoS映射处理还包含：CPE在向家庭接入网关发送UE的上行数据包之前，添加第一QoS标识。若CPE和家庭接入网关之间的第一链路上存在其他中间传输节点，则这些中间传输节点可以根据所述第一QoS标识，对数据包进行合理的转发处理，以保障UE数据的QoS要求。
可选的，上述CPE进行的QoS映射处理，可以在面向第一链路的链路层L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)执行；或者，另一可选的 方式中，在面向第一链路的适配层执行，所述适配层可位于L2之上(例如在IP层和L2之间)，在图5中并未示出。可选的，CPE在所述适配层的处理中，还可以添加第二指示信息和第三指示信息中的至少一种，用于指示所述数据包中携带的为UE的用户面数据。
家庭接入网关接收来自CPE的上行数据包，依次执行接收侧的L1和L2、IP、UDP、GTP层的处理，由于CPE和家庭接入网关之间通过与UE DRB一一对应的GTP隧道传输UE的用户面数据包，故家庭接入网关可通过GTP隧道的TEID，确定UE以及UE的DRB。然后将数据包(例如UE的上行PDCP PDU)交由接收侧与UE对等的PDCP层中，与UE DRB对应的PDCP实体处理，之后再交由与UE对等的SDAP层进行处理。
参照图6，UE的协议栈从高到低依次为：与家庭接入网关对等的SDAP层、与家庭接入网关对等的PDCP层、面向第二链路的Adapt层、面向第二链路的L2和面向第二链路的L1。CPE在与UE之间的第二链路对应接口上的协议栈从高到低依次为：面向第二链路的Adapt层、面向第二链路的L2层和面向第二链路的L1层，CPE在与家庭接入网关之间的第一链路对应接口上的协议栈从高到低依次为：面向第一链路的Adapt层、面向第一链路的L2和面向第一链路的L1。家庭接入网关的协议栈从高到低依次为：与UE对等的SDAP、与UE对等的PDCP层、面向第一链路的Adapt层、面向第一链路的L2和面向第一链路的L1。所述链路层L2和物理层L1对应的具体协议层可以参照参照图5所示协议结构的描述，这里不再赘述。同样，其他协议层的相关内容(包括面向第二链路的Adapt层的功能，以及该适配层的功能通过其他现有协议层实现的内容)可参照图5所示协议结构中的相应描述。
基于图6所示的协议架构，家庭接入网关对UE的下行数据包的处理如下：

可选的，若上述适配处理中的部分或全部过程由家庭接入网关在面向第一链路的L2(若链路层包含多个协议层，则可以是其中的任意某个协议层)和/或面向第一链路的L1执行，需要对第一链路实际使用的传输技术的L2和/或L1的功能进行扩展。
CPE收到来自家庭接入网关发送的下行数据包，将数据包经过其面向第一链路的协议栈的逐层接收处理得到UE的PDCP PDU，通过解析数据包携带的适配信息，获知数据包需要发送给UE，以及数据包对应的UE的无线承载，可选的，若所述适配信息中包含QoS flow的标识，则CPE还可以获知数据包对应的QoS flow，然后将UE的PDCP PDU交由发送侧处理。CPE发送侧的处理过程可参考图5所示协议架构中CPE对下行数据包的发送侧处理过程。CPE将经过面向第二链路的链路层和物理层处理后的数据包发送至UE，UE接收数据包后的处理过程可参考图5所示协议架构中UE对下行数据包的接收处理过程。
基于图6所示的协议架构，UE对上行数据包的处理和发送，可参考图5所示协议架构中UE对上行数据包的处理和发送过程描述进行理解。
CPE接收UE发送的上行数据包，经过其接收侧包含协议栈(即面向CPE与UE之间的第二链路的协议栈)的逐层处理后得到UE的PDCP PDU。在逐层处理过程中，CPE可根据接收数据包的逻辑信道，或者数据包中携带的UE的无线承载的标识(例如携带在适配层头部)，确定数据包对应的UE的无线承载，可选的，若所述数据包还携带UE的QoS flow的标识(例如携带在适配层头部)，则CPE还可确定数据包的QoS flow。
进一步，CPE对UE的上行数据包进行适配处理，以及面向第一链路的链路层处理。所述适配处理，包括QoS映射处理，和/或适配信息的添加。所述QoS映射处理可以包括：当第一链路为第一类链路时，CPE执行从UE QoS flow或UE的无线承载或第二QoS标识到CPE的无线承载的映射；当第一链路为第二类链路时，CPE执行从UE QoS flow或UE的无线承载或第二QoS标识到第一链路的第一QoS标识的映射，具体映射过程参照上述实施例中的相关描述，这里不再赘述。所述适配信息包括如下信息中的至少一种：UE的标识、UE无线承载的标识、UE QoS flow的标识、第一QoS标识、第二指示信息、第三指示信息。可选的，所述适配处理中的部分或全部过程可以是在以下任一协议层或任意多个协议层的处理中执行：面向第一链路的适配层、面向第一链路的链路层(若链路层包含多个协议层，则可以是其中的任意某个协议层)。例如，CPE可以在面向第一链路的适配层中添加UE的标识以及UE的无线承载标识，并执行从UE的无线承载到第一QoS标识的映射；在面向第一链路的链路层添加第一QoS标识等。然后，CPE将数据包递交至面向第一链路的物理层处理，并通过第一链路向家庭接入网关发送UE的上行数据包。
可选的，若上述适配处理中的部分或全部过程由CPE在面向第一链路的L2层(若链路层包含多个协议层，则可以是其中的任意某个协议层)执行，需要对第一链路实际使用的传输技术的L2层功能进行扩展。
家庭接入网关接收来自CPE的上行数据包，依次执行面向第一链路的L1和L2层和Adapt层的接收处理后得到UE的PDCP PDU，并根据数据包中携带的适配信息，确定UE以及UE的DRB，然后将数据包交由接收侧与UE对等的PDCP层中，与UE  DRB对应的PDCP实体处理，之后再交由与UE对等的SDAP层进行处理。
