下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明的一部分实施例, 而不 是全部实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创 造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。
本发明的技术方案, 可以应用于各种通信系统, 例如: 全球移动通信系 统 ( Global System of Mobile communication, GSM ),码分多址 ( Code Division Multiple Access, CDMA ) 系统, 宽带码分多址 ( Wideband Code Division Multiple Access Wireless, WCDMA ), 通用分组无线业务 ( General Packet Radio Service, GPRS ), 长期演进( Long Term Evolution, LTE )等。
基站,可以是 GSM或 CDMA中的基站( Base Transceiver Station, BTS ), 也可以是 WCDMA 中的基站 (NodeB ), 还可以是 LTE 中的演进型基站 ( evolved Node B , eNB或 e-NodeB ), 本发明并不限定。
图 1是根据本发明实施例的业务转发的方法的示意性流程图。 图 1的方 法由上行服务提供商边缘( Superstratum Provider Edge, SPE )设备执行。 110, 接收用户侧服务提供商边缘( User-end Provider Edge , UPE )设备在传 送隧道上发送的基站的上行报文, 上行报文携带基站网际协议 (Internet Protocol, IP )地址和传送隧道的 ID。
可选地, 作为一个实施例, 在步骤 110之前, SPE设备可以与 UPE设 备之间建立传送隧道, 传送隧道与 UPE设备上用于与基站通信的端口相对 应。
传送隧道可以是指 SPE设备与 UPE设备之间进行通信的隧道。 UPE设 备上可以有一个或多个端口, 这些端口用于与基站进行通信。 其中, 每个端 口对应于一个基站。 SPE设备与 UPE设备之间可以基于每个端口建立一个 传送隧道。 这样, 可以保证每个基站对应于单独的传送隧道。 因此, 在 SPE 设备与 UPE设备之间仍可以保持以太网专线( E-Line )连接。
可选地, 作为另一实施例, 传送隧道的 ID可以包括分组标签或物理管 道标识。 例如, 可以以 VLAN (比如服务 VLAN ( Service VLAN, SVLAN ) )、 端口、运营商骨干桥接( Provider Backbone Bridge, PBB )、伪线( Pseudo Wire, PW )或光通路数据单元(Optical Channel Data Unit, ODUk )等的标识对传 送隧道进行标示。
120, 根据上行报文, 建立基站 IP地址与传送隧道的 ID之间的映射关 系。
可选地, 作为另一实施例, 在步骤 110中, SPE设备可以接收 UPE设 备在传送隧道上发送的基站的上行地址解析协议 (Address Resolution Protocol, ARP )报文,上行 ARP报文携带基站接口 IP地址。在步骤 120中, SPE设备可以根据上行 ARP报文, 建立基站接口 IP地址与传送隧道的 ID 之间的映射关系。
在业务正常传输之前, 基站和基站网关之间通常会传输 ARP报文, 它 们可以通过 ARP报文获取对端端口地址。 此外, 在业务正常传输过程中, 基站和基站网关之间也会定期传输更新的 ARP报文。 本发明实施例中, 上 行 ARP报文可以是指从基站向基站网关的上行方向传输的 ARP报文。 UPE 设备接收到基站的原始上行 ARP报文后, 原始上行 ARP报文可以携带基站 接口 IP地址。 UPE设备可以在原始上行 ARP报文封装传送隧道的 ID得到 上行 ARP报文。 因此上行 ARP报文携带基站接口 IP地址和传送隧道的 ID。 SPE设备可以根据上行 ARP报文建立基站接口 IP地址与传送隧道的 ID之 间的映射关系。 当上行 ARP报文更新时, SPE设备还可以根据更新的上行 ARP报文, 更新上述映射关系。
应理解, SPE设备可以根据基站侧的容量需求, 规划一个或多个汇聚端 口。 一组基站对应一个汇聚端口。 SPE设备可以在内部为基站划分虚拟交换 转发( Virtual Switching Forwarding, VSF ), 通过 VSF可以自动挂接传送隧 道和相应的汇聚端口。 SPE设备可以通过汇聚端口将上行 ARP ^艮文转发给 基站网关。
可选地, 作为另一实施例, 在步骤 110中, SPE设备可以接收 UPE设 备在传送隧道上发送的基站的上行链路层发现协议(Link Layer Discovery Protocol, LLDP )报文, 上行 LLDP报文可以携带基站接口 IP地址、基站业 务逻辑 IP地址和传送隧道的 ID。 SPE设备可以根据上行 LLDP报文, 建立 基站接口 IP地址、 基站业务逻辑 IP地址与传送隧道的 ID之间的映射关系。 例如, 基站可以在上行 LLDP报文的 TLV ( Type-Length- Value, 类型- 长度 -值)信息串 ( information string )字段中携带基站接口 IP地址和基站业 务逻辑 IP地址。 UPE设备接收到该上行 LLDP报文后,可以在该上行 LLDP 报文中封装传送隧道的 ID。 那么 SPE设备从 UPE设备接收到封装后的上行 LLDP报文后, 可以建立基站接口 IP地址、 基站业务逻辑 IP地址与传送隧 道的 ID之间的映射关系。
由于上行 LLDP报文是基站向 SPE设备传送的报文, 因此在基站接口 IP重新规划的场景或者 SPE设备掉电重启而上行 ARP报文还未到更新周期 的场景中, 本发明实施例的根据上行 LLDP报文动态建立基站 IP地址与传 送隧道的 ID之间的映射关系的方案更为适用。
130, 根据映射关系, 在传送隧道上向 UPE设备发送下行业务报文, 其 中下行业务 ^艮文的目的 IP地址为该基站 IP地址。
SPE设备可以确定目的 IP地址为基站 IP地址的下行业务报文, 在映射 关系中确定与该 IP地址相对应的传送隧道的 ID, 从而在该传送隧道上向 UPE设备发送下行业务报文。
可选地, 作为另一实施例, SPE设备还可以接收 UPE设备在传送隧道 上发送的基站的上行业务报文, 通过传送隧道对应的汇聚端口, 向基站网关 发送上行业务报文。
SPE设备可以在接收到基站的上行业务报文后, 通过 VSF确定对应的 汇聚端口, 然后通过该汇聚端口向基站网关发送上行业务报文。
应理解, 上述下行业务报文和上行业务报文可以包括基站的业务数据以 及基站与基站网关之间的协议报文等。
本发明实施例中, 通过根据基站的上行报文动态建立基站 IP地址与传 送隧道的 ID之间的映射关系, 并根据该映射关系向 UPE设备发送下行业务 报文, 而无需依赖于 VLAN传送业务报文, 因此能够解除传送 VLAN与无 线 VLAN之间的耦合性,从而能够减少不同设备之间的协调工作量,便于进 行网络调整。
此外, 本发明实施例也无需对 IP地址进行规划和配置, 从而能够避免 IP地址的规划所带来的工作量。
