Capability Matching for Wired-Wireless HFC Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication capacity of Data Over Cable Service Interface Specification (DOCSIS) is limited, and existing wired communication infrastructure like HFC networks require upgrades to either Fiber To The Home (FTTH) or New Radio over Cable (NRoC), which pose challenges such as infrastructure waste and ecosystem reconstruction.
Innovation Solution
A method for terminal and network devices to perform matching between communication capabilities, transmit a matching result, and establish a wired communication connection based on configuration information, allowing communication via existing wired infrastructure without changing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DOCSIS standard is used for wired communication, then transmission quality and confidentiality are improved, but communication capacity is limited
Solution Approach 1:
The terminal device is designed to support both wired communication (via HFC network) and wireless communication (via air interface), enabling it to function in multiple communication modes. This multi-functionality allows the system to leverage the high reliability of wired DOCSIS communication while potentially achieving higher capacities through wireless modes, thus resolving the contradiction between transmission quality and communication capacity
Solution Approach 2:
The system dynamically changes communication parameters by selecting between wired and wireless communication modes based on capability matching results. The terminal device and network device exchange capability information and determine the optimal communication mode, allowing the system to adapt parameters such as communication interface type, protocol stack, and transmission characteristics to achieve both high reliability and sufficient capacity
2Productivity
If HFC network is upgraded to FTTH or NRoC, then communication capacity is improved, but infrastructure waste and ecosystem reconstruction challenges occur
Solution Approach 1:
The existing HFC infrastructure serves itself by enabling wireless communication capabilities over the wired connection. The terminal device performs self-configuration based on capability matching, automatically determining whether to use wired or wireless mode without requiring manual infrastructure upgrades. This allows the HFC network to provide enhanced capacity through software and protocol optimizations rather than physical upgrades, avoiding infrastructure waste
Solution Approach 2:
A capability matching mechanism acts as an intermediary between the terminal device and network device, enabling them to negotiate and select the most appropriate communication mode (wired or wireless). This intermediary process allows the system to achieve higher communication capacity through intelligent resource allocation and mode selection rather than through costly infrastructure upgrades, thereby preventing infrastructure waste

AI summary
A method for communication includes performing at a terminal device, matching between a first communication capability of the terminal device and a second communication capability of a network device, the first and second communication capabilities indicating first and second wired and wireless communication capabilities, respectively; transmitting a matching result for to the network device, the matching result indicating whether the first communication capability successfully matches or fails to match the second communication capability; receiving, from the network device, configuration information for a wired communication connection between the terminal device and the network device based on the matching result indicating that the first communication capability successfully matches the second communication capability; and performing communication with the network device via the wired communication connection based on the configuration information.
