Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for providing connectivity between subscriber domains and remote networks via customer premises equipment suffer from limitations in controlling downstream instances and managing bandwidth efficiently, particularly in wireless network environments.
Innovation Solution
Implementing a communication management resource that allocates bandwidth in a physical communication link based on wireless bandwidth supported by customer premises equipment, establishing a control channel for managing and controlling the operation of customer premises equipment, and partitioning the link into sub-bands to facilitate efficient data conveyance and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bandwidth in a physical communication link is allocated to convey communication data associated with customer premises equipment, then data flow efficiency is improved, but control capability over downstream instances of customer premises equipment deteriorates
Solution Approach 1:
The patent segments the physical communication link into multiple logical channels, including a control channel and data channels. The control channel is specifically allocated for management traffic between the network management node and customer premises equipment, while other channels handle data traffic. This segmentation allows simultaneous optimization of both control capability and data flow efficiency without interference between control and data traffic.
2Adaptability or versatility
If the physical communication link is partitioned into sub-bands based on wireless bandwidth supported by customer premises equipment, then bandwidth utilization is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic sub-band allocation where the physical communication link is partitioned into multiple sub-bands based on the real-time wireless bandwidth capabilities of customer premises equipment. The system dynamically adjusts which sub-bands are allocated to which CPE instances according to their specific requirements, enabling adaptive bandwidth utilization while managing complexity through automated resource allocation algorithms.
3Ease of operation
If a control channel is established over the physical communication link for transmitting control messages, then control capability is improved, but available bandwidth for data transmission is reduced
Solution Approach 1:
The patent introduces a dedicated control channel as an intermediary pathway for management traffic. This control channel operates separately from data channels, allowing control messages to be transmitted without competing for bandwidth with data traffic. The control channel acts as a mediator that enables reliable control capability while preserving data transmission bandwidth through logical channel separation.

AI summary
A communication management resource (such as disposed at a network management node or other location) allocates bandwidth in a physical communication link to convey communication data associated with first customer premises equipment. In one implementation, the allocated bandwidth in the physical communication link is partitioned in accordance with wireless bandwidth supported by the first customer premises equipment. For example, in one embodiment, the allocated bandwidth of the physical communication link is mapped to convey corresponding data communicated over wireless bandwidth used by the first customer premises equipment. The communication management resource establishes a control channel over the physical communication link between the network management node and the first customer premises equipment. Via the control channel, the communication management resource then transmits a command over the control channel from the network management node to the first customer premises equipment. The command controls operation of the first customer premises equipment.
