具体实施方式
图1是本发明实施例的5G应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本发明实施例仅以5G通信系统100进行示例性说明,但本发明实施例不限定于此。也就是说,本发明实施例的技术方案可以应用于包括5G通信系统的各种场景。例如,5G通信系统和第一通信系统构成混合部署聚合场景等等。其中,该第一通信系统可以是任一种通信系统。例如: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)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
此外,本发明结合网络设备和终端设备描述了各个实施例。
其中,网络设备120可以指网络侧的任一种用来发送或接收信号的实体。例如,5G网络中的基站设备等。
终端设备110可以是任意终端设备。具体地,终端设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,也可称为接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如,可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备等。
应理解,由于LTE与5G NR不具有兼容性,图1所示的场景,并不支持5G NR终端通过非授权技术接入到5G RAN中。现有技术也没有提供灵活的层2或者层3接入选择给5G终端和5G RAN。
因此,本发明实施例中提供了一种接入无线接入网(Radio Access Network,RAN)的方法、设备和非授权接入点,通过用户面的协议层的适配,进而通过非授权的无线接口接入到5G RAN,不仅使得终端能够获取更大的接入速率,而且能够降低成本。
图2是本发明实施例的接入无线局域网的方法的示意性流程图。应理解,本发明实施例的方法可以应用于第五代移动通信技术5G通信系统。
具体地,如图2所示,该方法包括:
210,第一设备通过协议适配层生成目标数据。
220,第一设备向非授权接入点发送该目标数据。
230,该非授权接入点向第二设备转发该目标数据。
具体而言,第一设备通过协议适配层生成目标数据;该第一设备通过非授权接入点AP的互连网的协议(Internet Protocol,IP)层和/或媒体接入控制(Media Access Control,MAC)层,向第二设备发送该目标数据。话句话说,该非授权接入点的互联网协议IP层和/或媒体接入控制MAC层,接收第一设备发送的目标数据;该非授权AP向第二设备转发该目标数据。
图3是本发明实施例的协议适配层的位置的示意性框图。
具体地,如图3所示,该协议适配层与该第一设备的分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层相邻,且在该PDCP层的下方。换句话说,在如图3所示架构中,第一设备具有NR授权和NR非授权两种无线(radio)接口。
其中,NR授权无线接口可以与接入网设备通过空口连接传输数据,即该NR授权无线接口可以和接入网设备之间建立直接的逻辑信道。非授权无线接口没有直接和接入网设备进行数据传输,而是通过一个支持非授权的空中接口(例如,WLAN协议,又例如,包括非授权频段上的NR协议的其他非授权频段的协议)进行数据传输。
本发明实施例中,以上行用户数据传输为例进行说明,非授权接入点AP能够通过非授权接口(例如,如图3所示的非授权AP的L1接口和/或L2接口)与第一设备的非授权无线接口(例如,如图3所示的第一设备的L1接口和/或L2接口)进行数据传输,并且通过有线或者无线的回程(backhaul)链路与接入网设备建立连接。
可以看出,本发明实施例中,通过该协议适配层,使得5G系统的服务 质量数据流(Quality of Service flow,QoS Flow)以及用户面数据无线承载(DRB)能够通过非授权技术接入到5G RAN系统中。换句话说,本发明实施例中,可以为第一设备引入一个新的协议适配层。该协议适配层的主要功能是:将第一设备在各个数据无线承载上的PDU通过非授权无线接口向第二设备发送。
应理解,该新的协议适配层可以如图3所示的位于PDCP协议相邻的下层。进而,通过非授权AP可以提供IP层(即L3)或者MAC层(即L2)传输目标数据。但是,本发明实施例不限于此。
例如,该协议适配层还可以与该第一设备的无线链路层控制协议(Radio Link Control,RLC)层相邻,且在该RLC层的下方。
还应理解,作为示例而非限定性地,本发明实施例中的第一设备和第二设备还可以包括:物理层(Physical Layer,PHY)和服务数据适应协议(Service Data Adaptation Protocol,SDAP)。
下面对本发明实施例中该第一设备生成目标数据的实现方式进行示例性说明:
在一个实施例中,该非授权AP具有IP层。
由此,该第一设备通过该协议适配层生成目标数据,该目标数据包括:第一信息、源IP地址和目标IP地址,该第一信息为该第一设备的PDCP协议数据单元(Protocol Data Unit,PDU)或者RLC PDU。进而,该非授权AP接收到该目标数据后,可以根据该目标IP地址,向第二设备转发该目标数据。例如,如图4所示,该目标数据可以包括:PDCP PDU、源IP地址和目标IP地址。又例如,图5所示,该目标数据可以包括:RLC PDU、源IP地址和目标IP地址。
进一步地,该第一设备通过协议适配层生成目标数据之前,该第一设备还需要获取该目标IP地址。换句话说,当非授权AP提供协议IP层传输功能时,本发明实施例中的协议适配层需要第二设备提供一个IP地址,封装在第一设备发往第二设备的目标数据中作为目的地址。
应理解,该IP地址为核心网络设备为该第一设备分配的地址,或者,该IP地址为接入网设备为该第一设备分配的地址。本发明实施例不做具体限定。
应理解,图4和图5所示目标数据中,如果该目标数据为上行数据,则 上述源IP地址为终端设备的IP地址,该目标IP地址为接入网设备的IP地址。相应的,如果该目标数据为下行数据,则上述源IP地址为接入网设备的IP地址,该目标IP地址为终端设备的IP地址。
在另一个实施例中,该非授权AP具有MAC层。
由此,该第一设备通过该协议适配层生成目标数据,该目标数据可以包括:第一信息、源MAC地址和目标MAC地址,该第一信息为该第一设备的PDCP协议数据单元PDU或者RLC PDU。进而,该非授权AP接收到该目标数据后,可以根据该目标MAC地址,向第二设备转发该目标数据。例如,如图4所示,该目标数据可以包括:PDCP PDU、源MAC地址和目标MAC地址。又例如,图5所示,该目标数据可以包括:RLC PDU、源MAC地址和目标MAC地址。
进一步地,该第一设备通过协议适配层生成目标数据之前,该第一设备还需要获取该目标MAC地址。换句话说,当非授权AP提供协议MAC层传输功能时,本发明实施例中的协议适配层需要第二设备提供一个MAC地址,封装在第一设备发往第二设备的目标数据中作为目的地址。
应理解,该MAC地址可以为虚拟地址。但本发明实施例不做具体限定。
综上所述,本发明实施例的第一设备的协议适配层可以通过非授权接入点的IP层和/或MAC层传输把PDCP PDU或RLC PDU传输到第二设备。进而通过无线接入网实现终端设备和接入网设备的数据传输。
具体地,接入网设备可以通过无线资源控制(Radio Resource Control,RRC)信令来配置IP地址信息或者MAC地址信息。进一步地,IP或者MAC地址的分配过程,可以是终端设备进行附着(attach)过程中进行的操作,也可以是处于连接态的终端设备通过接入网设备通过主小区(PCell)的RRC信令来配置。
需要注意的是,本发明实施例中协议适配层是用户面的,但是也可以通过控制面的进行控制。具体地,控制面可以根据用户面的协议适配层的位置生成目标数据,例如,适配层位于PDCP以下还是RLC以下,IP层封装还是MAC层封装。
还应理解,图6和图7所示目标数据中,如果该目标数据为上行数据,则上述源MAC地址为终端设备的MAC地址,该目标MAC地址为接入网设备的MAC地址。相应的,如果该目标数据为下行数据,则上述源MAC 地址为接入网设备的MAC地址,该目标MAC地址为终端设备的MAC地址。
此外,在本发明实施例中,如图4至图7所示,该目标数据还可以包括:有效负载类型信息(payload type),该有效负载类型信息用于标识该目标数据中第一信息的类型。
进一步地,本发明实施例中的payload type,对于IP层封装来说,可以扩充IP协议,即,增添新的类型字段说明IP净负荷内容。对于MAC层封装来说,也可以扩充MAC协议字段,说明MAC净负荷内容。但本发明实施例不做具体限定。
例如,本发明实施例中,也可以不扩充IP协议字段或者MAC协议字段,而是把RLC PDU封装在IP包头中。
还应理解,本发明实施例中,该第一设备为终端设备且该第二设备为接入网设备;或者,该第一设备为接入网设备且该第二设备为终端设备。换句话说,本发明实施例中,该第一设备为终端设备且该第二设备为接入网设备时,图2所示的方法为终端设备向接入网设备发送上行用户数据的方法。该第一设备为接入网设备且该第二设备为终端设备时,图2所示的方法为接入网设备向终端设备发送下行用户数据的方法。
最后需要说明的是,本发明实施例中的非授权的AP,可以是支持地址解析协议(Address Resolution Protocol,ARP)代理(Proxy)功能或者层2的桥接功能的设备,以便实现终端设备和接入网设备之间的层2通信机制。
图8是本发明实施例的设备的示意性框图,应理解,该设备可以应用于第五代移动通信技术5G通信系统。
具体地,如图8所示,该设备300包括:
处理单元310,用于通过协议适配层生成目标数据;
收发单元320,用于通过非授权接入点AP的互联网协议IP层和/或媒体接入控制MAC层,向第二设备发送该目标数据。

可选地,该处理单元310还用于:

可选地,该MAC地址为虚拟地址。
可选地,该目标数据还包括:有效负载类型信息,该有效负载类型信息用于标识该目标数据中第一信息的类型。
可选地,该设备为终端设备且该第二设备为接入网设备;或者,该设备为接入网设备且该第二设备为终端设备。

可选地,该IP地址为核心网络设备为该第一设备分配的地址,或者,该IP地址为接入网设备为该第一设备分配的地址。
可选地,该非授权AP具有MAC层,该目标数据包括:第一信息、源MAC地址和目标MAC地址,该第一信息为该第一设备的PDCP协议数据单元PDU或者RLC PDU;其中,该转发单元520具体用于:
