DATA TRANSMISSION METHOD, APPARATUS, AND SYSTEM
First Claim
1. A data transmission method, wherein the method comprises:
- determining, by a cable modem termination system physical (CMTS PHY) layer according to uplink resource assignment information configured by a cable modem termination system Media Access Control (CMTS MAC) layer separately for each cable modem CM of multiple CMs, a time slice that needs to be occupied when uplink data sent from a CM connected to the CMTS PHY layer, is forwarded to the CMTS MAC layer; and
forwarding, by the CMTS PHY layer to the CMTS MAC layer on the determined time slice, the received uplink data that is sent, by using the uplink resource assignment information configured by the CMTS MAC layer, by the CM connected to the CMTS PHY layer.

Abstract
The present invention discloses a data transmission method, apparatus, and system, which are used to reduce a delay of user uplink data and improve network performance in an HFC network. The method includes: determining, by a cable modem termination system physical layer CMTS PHY layer according to uplink resource assignment information configured by a cable modem termination system Media Access Control layer CMTS MAC layer separately for each cable modem CM of multiple CMs, a time slice that needs to be occupied when uplink data sent from a CM connected to the CMTS PHY layer, is forwarded to the CMTS MAC layer; and forwarding, by the CMTS PHY layer to the CMTS MAC layer on the determined time slice, the received uplink data that is sent, by using the uplink resource assignment information configured by the CMTS MAC layer, by the CM connected to the CMTS PHY layer.
