Description
一种空口传输方法及相关设备、 系统 技术领域
本申请涉及通信技术领域,具体涉及一种空口传输方法及相关设备、系统。 背景技术
在通信网络中,通信双方通过有线传输可以有效地提高传输的性能和传输 的可靠性。 然而, 有线传输有时可能会受到市政工程、 实际环境等因素限制而 无法实施, 因此, 无线传输通常作为移动网络的重要组成部分。
在实际应用中,通常在有线传输的通信双方之间引入无线回传设备(如基 站、 接入点等)以实现通信双方的无线传输。 例如, 可以在有线传输的通信双 方之间引入两个无线回传设备, 其中一个无线回传设备和一个通信方有线连 接, 另一个无线回传设备和另一个通信方有线连接, 而这两个无线回传设备之 间无线 (wireless )连接, 从而形成通信双方的无线空口连接, 使通信双方之 间可以进行无线传输。 以第三代合作伙伴计划 ( The 3rd Generation Partnership Project, 3GPP ) 的长期演进( Long Term Evolution, LTE ) 为例, 在有线传输 的通信双方之间引入无线回传设备(如基站、接入点等)以实现通信双方的无 线传输时, 空口协议如图 1所示, 其中, 无线接入层协议(Radio Protocol )从 下到上依次为无线物理( Radio PHY )层、媒体访问控制( Media Access Control, MAC )层、无线链路控制( Radio Link Control, RLC )层、分组数据汇聚( Packet Data Convergence Protocol, PDCP )层, 而 Radio Protocol的上层 ?1 ^载 IP帧数 据。
从图 1中可以知看出, 由于通信双方的无线空口传输的是 IP帧数据, 因 此需要为无线空口两侧的无线回传设备分配 IP地址,并且修改网络路由配置, 导致 IP地址的消耗。 发明内容

下面将结合本申请实施例中的附图,对本申请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申请一部分实施例, 而不是 全部的实施例。基于本申请中的实施例, 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例, 都属于本申请保护的范围。
为了更好的理解本申请提供的空口传输方法及相关设备、 系统,在详细论
述本申请提供的空口传输方法及相关设备、 系统之前, 先对本申请所应用的场 景进行清楚描述,通过对本申请所应用的场景进行清楚描述, 本领域普通技术 人员对于本申请提供的空口传输方法及相关设备、系统所带来的优点将会有一 个更深刻的认识。
请参阅图 2, 图 2表示通信网络中第一网元设备 A和第二网元设备 E有线连 接的示意图,其中, IP1和 IP2分别是第一网元设备 A和第二网元设备 E在通信时 的 IP地址。 由于第一网元设备 A和第二网元设备 E之间的有线传输有时可能会 受到市政工程、 实际环境等因素限制而无法实施, 因此, 可以如图 3所示在第 一网元设备 A和第二网元设备 E之间引入第一无线回传设备 B和第二无线回传 设备 C, 其中, 第一网元设备 A和第一无线回传设备 B有线连接, 第二网元设备 E和第二无线回传设备 C有线连接,而第一无线回传设备 B和第二无线回传设备 C之间无线 ( wireless )连接, 从而形成第一网元设备 A和第二网元设备 E之间 的无线空口连接, 实现第一网元设备 A和第二网元设备 E之间的无线传输。 然 而, 第一无线回传设备 B和第二无线回传设备 C之间的采用了如图 1所示的无线 空口协议栈, 也即是说第一无线回传设备 B和第二无线回传设备 C之间的无线 空口传输的是 IP帧数据, 因此需要分别为第一无线回传设备 B和第二无线回传 设备 C分配 IP地址 IP3和 IP4, 这不仅消耗了 IP地址, 而且还需要修改网络路由 配置。
为了解决上述缺陷, 本申请实施例提供了一种空口传输方法及相关设备、 系统, 能够减少 IP地址消耗以及无需修改网络路由配置。 本申请实施例提供 的空口传输方法中, 第一无线回传设备接收以太帧数据, 并利用自身支持的无 线接入制式对应的无线接入层协议对该以太帧数据进行封装,获得封装后的以 太帧数据; 以及通过无线空口将封装后的以太帧数据传输给第二无线回传设 备。 以下分别进行详细说明。
请参阅图 4a, 图 4a是本申请实施例提供的一种空口传输方法的流程图。 如 图 4a所示, 该空口传输方法可以包括以下步骤。
401a,第一无线回传设备接收与第一无线回传设备有线连接的第一网络设 备传输过来的以太帧数据。
402a,第一无线回传设备利用自身支持的无线接入制式对应的无线接入层
协议( Radio Protocol )对第一网络设备传输过来的以太帧数据进行封装, 获得 封装后的以太帧数据。
403a、第一无线回传设备通过与第二无线回传设备之间的无线空口连接将 封装后的以太帧数据传输给第二无线回传设备,以使第二无线回传设备利用自 身支持的无线接入制式对应的 Radio Protocol对封装后的以太帧数据进行解封 装以获得以太帧数据, 并传输给第二无线回传设备有线连接的第二网元设备。
图 4a所描述的方法中,直接在第一无线回传设备和第二无线回传设备之间 传输以太帧数据,使得引入的位于无线空口两侧的第一、第二无线回传设备可 以看作 ^^于以太头交换的 "交换机" 设备, 而不需要引入新的网络 IP规划, 从而可以减少 IP地址消耗, 进而也无需修改移动网络的路由配置。
请参阅图 4b , 图 4b是本申请实施例提供的另一种空口传输方法的流程图。 如图 4b所示, 该空口传输方法可以包括以下步骤。
401b、第一无线回传设备接收与第一无线回传设备有线连接的第一网络设 备传输过来的以太(ETH ) 帧数据。
本申请中, 第一无线回传设备可以是宏基站, 也可以是微基站, 或者是其 他无线接入节点, 本申请不作限定。
本申请中, 第一网络设备可以是基站控制器, 也可以是核心网设备, 例如 移动管理实体(Mobile Management Entity, MME )或其他对等网元, 也可以 是其他用户终端 (如个人电脑)、 接入网络设备, 本申请不作限定。
本申请中, 以太帧数据也称为数据链路层数据, 举例来说, 以太帧数据可 以是在 IP帧数据的基础上进一步封装以太头 ( ETH header )得到, 而 IP帧数 据通常是由净荷 ( Payload ) 依次经过流控制传输协议 ( Stream Control Transmission Protocol, STCP )/用户数据报协议( User Datagram Protocol, UDP )、 IP头封装后得到。 即, 一种以太帧数据的格式可以如下表 1所示:
表 1
Payload
STCP/ UDP
IP头
ETH头
402b,第一无线回传设备解析第一网络设备传输过来的以太帧数据(如以 太帧头), 获得映射标识。
本申请中,第一无线回传设备利用上述映射标识可以查询到用于传输以太 帧数据的指定服务质量类别标识( QoS Class Identifier, QCI )的无线承载资源。
本申请中,第一无线回传设备解析以太帧数据获得的映射标识可以由多个 参数组合而成, 例如, 映射标识可以由原有的源媒体接入控制 (Media Access Control, MAC )地址、 目的 MAC 地址等参数以及扩展的虚拟局域网标识 ( VLAN ID )、虚拟局域网优先级类型(VLAN priority type )这些参数组合而 成。 本申请中, VLAN ID、 VLAN priority type可以在以太帧数据的可见字 段中扩展得到。
403b, 第一无线回传设备根据该映射标识, 从传输流模板 ( Traffic Flow Template, TFT ) 中查询该映射标识对应的指定服务质量类别标识( QoS Class Identifier, QCI ) 的无线承载资源。
本申请中, 第一无线回传设备可以根据该映射标识, 从 TFT所绑定的映 射标识与指定 QCI的无线承载资源的对应关系中查询该映射标识对应的指定 QCI的无线承载资源。
本申请中, 可以对 TFT进行如下扩展:
• VLAN ID type
• VLAN priority type 本申请中,由于 TFT在未扩展前已经携带了以太帧数据中原有的参数 (如 源 MAC地址、 目的 MAC地址等), 那么当以太帧数据的可见字段中扩展出 VLAN ID、 VLAN priority type之后, 相应地也可以对 TFT进行扩展, 使扩展 后的 TFT中也携带 VLAN ID、 VLAN priority type , 从而使扩展后的 TFT携带 的参数组合与以太帧数据的参数组合相同, 即 TFT中用于构成映射标识的参 数组合与以太帧数据中用于构成映射标识的参数组合相同。从而, 第一无线回 传设备可以根据以太帧数据的映射标识, 从 TFT 中查询该映射标识对应的指 定 QCI的无线承载资源。
本申请之前, 映射标识也可以取 IP协议中的 T0S字段中低 6bit的差分服 务代码点 ( Differentiated Services Code Point ), 相应地本申请可以对映射标识
进行扩展, 使得映射标识不仅仅可以依靠 IP协议中的 TOS字段中低 6bit的 DSCP, 也可以依赖于 802.1Q的 VLAN字段(包括 VLAN ID、 VLAN priority type )。
本申请中, 在以太帧数据的可见字段以及 TFT 中扩展 VLAN ID type, VLAN priority type, 可以查询出更优的指定 QCI的无线承载资源, 从而可以 扩展 QoS的保证范围。
404b,第一无线回传设备利用自身支持的无线接入制式对应的无线接入层 协议( Radio Protocol )对该以太帧数据进行封装, 获得封装后的以太帧数据。
本申请中,第一无线回传设备支持的无线接入制式对应的无线接入层协议 ( Radio Protocol )可以是第三代合作伙伴计划长期演进(The 3rd Generation Partnership Project LTE, 3GPP LTE )制式对应的 Radio Protocol, 也可以是宽 带码分多址接入( Wideband Code Division Multiple Access , WCDMA )制式对 应的 Radio Protocol , 也可以是时分同 步码分多 址接入 ( Time Division-Synchronous Code Division Multiple Access , TD-SCDMA )制式对应的 Radio Protocol,或者是码分多址接入 2000( Code Division Multiple Access 2000, CDMA2000 )制式对应的 Radio Protocol, 本申请不作具体限定。
405b、 第一无线回传设备通过与第二无线回传设备之间的无线空口连接, 利用该映射标识对应的指定 QCI的无线承载资源将封装后的以太帧数据传输 给第二无线回传设备,以使第二无线回传设备利用自身支持的无线接入制式对 应的 Radio Protocol对封装后的以太帧数据进行解封装以获得以太帧数据, 并 传输给第二无线回传设备有线连接的第二网元设备。
本申请中, 第二无线回传设备可以是无线接入节点, 交换机, 路由器, 也 可以是其他热点设备, 本申请不作限定。
本申请中, 第二网络设备可以是宏基站、 微基站, 也可以是其他用户终端 (如个人电脑)、 接入网设备, 本申请不作限定。
本申请中,第二无线回传设备支持的无线接入制式对应的无线接入层协议 ( Radio Protocol )可以是 3GPP LTE制式对应的 Radio Protocol, 也可以是 WCDMA制式对应的 Radio Protocol,也可以是 TD-SCDMA制式对应的 Radio Protocol, 或者是 CDMA2000制式对应的 Radio Protocol, 本申请不作具体限 定。 本申请中, 第二无线回传设备支持的无线接入制式对应的 Radio Protocol
与第一无线回传设备支持的无线接入制式对应的 Radio Protocol相同。 请一并参阅图 5, 图 5为本申请提供的第一无线回传设备与第二无线回传 设备之间的空口协议示意图。如图 5所示, 第一无线回传设备支持的无线接入 制式对应的 Radio Protocol可以封装以太帧数据 (如包括 IP帧数据和 ETH头 ) 组成; 而第二无线回传设备支持的无线接入制式对应的 Radio Protocol可以封 装以太帧数据(如包括 IP帧数据和 ETH头)组成。 需要说明的是, 以太帧数 据也可以又其他净荷(Payload )和 ETH头组成, 本申请不作限定。
举例来说, 当第一无线回传设备、第二无线回传设备支持的无线接入制式 是 3GPP LTE制式时, 3GPP LTE制式对应的 Radio Protocol从下到上依次为 Radio PHY层、 MAC层、 RLC层、 PDCP层, 那么相应地, 第一无线回传设 备与第二无线回传设备之间的空口协议示意图可以如图 6所示。
需要说明的是, 当第一无线回传设备、第二无线回传设备支持的无线接入 制式是其他制式时, 其他制式对应的 Radio Protocol也是本领域技术人员所公 知的常识, 本申请不作赘述。
本申请中, 在无线空口直接传输封装后的以太帧数据会导致开销的增加, 因此, 第一无线回传设备在通过与第二无线回传设备之间的无线空口连接, 利 用该映射标识对应的指定 QCI的无线承载资源将封装后的以太帧数据传输给 传输给第二无线回传设备之前, 可以对封装后的以太帧数据进行头压缩处理, 以提高无线空口传输效率。
本申请直接在第一无线回传设备和第二无线回传设备之间传输以太帧数 据(又称数据链路层帧), 使得引入的位于无线空口两侧的第一、 第二无线回 传设备可以看作是基于以太头交换的 "交换机"设备, 而不需要引入新的网络 IP规划, 从而可以减少 IP地址消耗, 进而也无需修改移动网络的路由配置。
请参阅图 7, 图 7是本申请实施例提供的另一种空口传输方法的流程图。如 图 7所示, 该空口传输方法可以包括以下步骤。
701、 第二无线回传设备通过与第一无线回传设备之间的无线空口连接接 收第一无线回传设备传输过来的封装后的以太帧数据; 其中, 该封装后的以太 帧数据是由第一无线回传设备接收到第一无线回传设备有线连接的第一网络 设备传输过来的以太帧数据之后,利用第一无线回传设备自身支持的无线接入
制式对应的 Radio Protocol对第一网络设备传输过来的以太帧数据进行封装得 到。
702、 第二无线回传设备利用自身支持的无线接入制式对应的 Radio Protocol对封装后的以太帧数据进行解封装以获得以太帧数据, 并传输给第二 无线回传设备有线连接的第二网元设备。
本申请中,若第一无线回传设备传输过来的封装后的以太帧数据经过头压 缩处理, 则第二无线回传设备利用自身支持的无线接入制式对应的 Radio Protocol对封装后的以太帧数据进行解封装以获得以太帧数据之前, 第二无线 回传设备可以先对该封装后的以太帧数据进行头解压缩处理,然后再利用第二 无线回传设备自身支持的无线接入制式对应的 Radio Protocol对封装后的以太 帧数据进行解封装以获得以太帧数据并传输给第二无线回传设备有线连接的 第二网元设备。

图 14所示的空口传输系统中,第一无线回传设备 1401可以通过与第二无线 回传设备 1402之间无线空口连接直接传输以太帧数据 (又称数据链路层帧 )给 第二无线回传设备 1402,从而使得位于无线空口两侧的无线回传设备可以看作 是基于以太头交换的 "交换机"设备, 而不需要引入新的网络 IP规划, 从而可 以减少 IP地址消耗, 进而也无需修改移动网络的路由配置。
请参阅图 15 ,图 15是本申请实施例提供的另一种空口传输系统的结构图。 如图 15所示, 该系统可以包括:
第一无线回传设备 1501、 第二无线回传设备 1502、 第一网元设备 1503 以及第二网元设备 1504, 其中, 第一无线回传设备 1501可以是 eRday系统中 的基站 (Base Station, BS ), 第二无线回传设备 1502可以是 eRday系统中的 无线接入节点( eRelay Radio Node , RRN ) , 第一网元设备 1503可以是基站控 制器或核心网设备(如 ΜΜΕ ),第二网元设备 1504可以是微基站( Small Cell )。 如图 15所示, 第一无线回传设备 1501与第一网元设备 1503之间可以通过传 输网络(Transport network )有线连接, 第二无线回传设备 1502与第二网元设 备 1504之间可以通过有线连接,而第一无线回传设备 1501与第二无线回传设 备 1502之间可以通过无线空口连接。 本申请中, 当第一无线回传设备 1501 是 eRday系统中的 BS时, 第一无线回传设备 1501的部署比较灵活, 如图 15 所示,第一无线回传设备 1501 (即 eRelay系统中的 BS )可以和宏基站( Macro Cell )共站部署。
请一并参阅图 16, 图 16为图 15所示的空口协议示意图。 在图 16所示的 空口协议中, 假设第一无线回传设备 1401、 第二无线回传设备 1502支持的无 线接入方式为 3GPP LTE制式。 如图 16所示, 第一网元设备 1503通过 L1层 交换将以太帧数据 (假设以太帧数据由 IP帧数据封装 ETH头构成)给第一无
线回传设备 1501; 第一无线回传设备 1401接收第一网络设备 1403传输过来 的以太帧数据, 并解析该以太帧数据的以太帧头, 获得映射标识, 以及根据该 映射标识, 从 TFT中查询该映射标识对应的指定 QCI的无线承载资源; 以及 利用自身支持的 3GPP LTE制式对应的 Radio Protocol (该 Radio Protocol从下 到上依次为 Radio PHY层、 MAC层、 RLC层、 PDCP层)对该以太帧数据进 行封装, 获得封装后的以太帧数据, 以及通过与第二无线回传设备 1502之间 的无线空口连接, 利用该映射标识对应的指定 QCI的无线承载资源将该封装 后的以太帧数据传输给第二无线回传设备 1502; 第二无线回传设备 1502接收 第一无线回传设备 1501传输过来的封装后的以太帧数据, 并且利用自身支持 的 3GPP LTE制式对应的 Radio Protocol (该 Radio Protocol从下到上依次为 Radio PHY层、 MAC层、 RLC层、 PDCP层)对该封装后的以太帧数据进行 解封装以获得以太帧数据, 并传输给第二网元设备 1504; 第二网元设备 104 接收第二无线回传设备 102传输过来的以太帧数据。
本申请提供的空口传输系统可以应用于 eRday系统, 而且第一无线回传 设备 1501可以通过与第二无线回传设备 1502之间无线空口连接直接传输以太 帧数据(又称数据链路层帧)给第二无线回传设备 1502, 从而使得位于无线 空口两侧的无线回传设备可以看作是基于以太头交换的 "交换机"设备, 而不 需要引入新的网络 IP规划, 从而可以减少 IP地址消耗, 进而也无需修改移动 网络的路由配置。
在图 15所示的系统中, 选用 3GPP LTE制式作为无线接入制式, 是因为 3GPP LTE制式在带宽、 空口性能等方面的优势,也是下一代的无线接入制式。 但是, 本申请并不限定于 3GPP LTE制式。 当设备成本、 需求规格不同时。 也 可以采用如 WCDMA、 TD-SCDMA、 CDMA2000等无线接入方式直接承载 以太帧数据。
本申请中,位于无线空口两侧的无线回传设备直接传输以太帧数据,使得 无线空口两侧呈现 L2层转发形态(即呈现交换机形态 ),这种形态即可以看作 "无线交换机", 对于难以部署有线交换设备场景或者难以提供有线传输的场 景, 本申请都可以有效的解决。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步 骤是可以通过程序来指令相关的硬件来完成,该程序可以存储于一计算机可读 存储介质中, 存储介质可以包括: 闪存盘、 只读存储器(Read-Only Memory , ROM ), 随机存取器(Random Access Memory, RAM ), 磁盘或光盘等。
