Abstract: Embodiments of the present invention provide a service forwarding method and device. The method includes receiving an uplink packet of a base station that is sent by a user-end provider edge (UPE) device over a transport tunnel. The uplink packet carries an Internet Protocol (IP) address of the base station and an identifier of the transport tunnel. The method further includes establishing a mapping relationship between the IP address of the base station and the identifier of the transport tunnel according to the uplink packet, and sending a downlink service packet to the UPE device over the transport tunnel according to the mapping relationship. A destination IP address of the downlink service packet is the IP address of the base station.

Abstract translation: 本发明的实施例提供一种服务转发方法和装置。 该方法包括：通过传输隧道接收由用户端提供商边缘（UPE）设备发送的基站的上行链路分组。 上行链路分组携带基站的因特网协议（IP）地址和传输隧道的标识符。 该方法还包括根据上行链路分组建立基站的IP地址与传输隧道的标识符之间的映射关系，并根据映射关系通过传输隧道向UPE设备发送下行业务报文。 下行业务分组的目的地IP地址是基站的IP地址。
