Abstract:
1. A base station access system, comprising: a base station, configured to assign sequence number identifications to uplink point to point protocol (PPP) packets using a multi-link point to point protocol (ML-PPP) so as to form uplink ML-PPP packets and map the uplink ML-PPP packets with the sequence number identifications into Ethernet frames and send the Ethernet frames to a digital subscriber line access multiplexer via multiple digital subscriber lines (DSL) links; and further configured to receive downlink ML-PPP packets sent via the multiple DSL links, arrange the downlink ML-PPP packets according to sequence number identifications of the received downlink ML-PPP packets using the ML-PPP, extract downlink data packets and send the downlink data packets; and a broadband access point, configured to receive the Ethernet frames containing the uplink ML-PPP packets transferred via the multiple DSL links, arrange the uplink ML-PPP packets according to the sequence number identifications of the received uplink ML-PPP packets using the ML-PPP, extract uplink data packets and send the uplink data packets; and configured to assign sequence number identifications to downlink PPP packets using the ML-PPP so as to form the downlink ML-PPP packets and send the downlink ML-PPP packets via the multiple DSL links.
