Control Channel Positioning for Dynamic Wireless Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic channel assignment methods in wireless communications face high computation and control complexity, which hinders efficient channel allocation and utilization.
Innovation Solution
A method where a control channel is selected from idle channels and signaled to customer premise equipment (CPE) for communication requests, allowing dynamic channel assignment with reduced computational burden and complexity by positioning CPEs on the same control channel for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic channel assignment method is used to achieve flexible channel allocation, then channel utilization is improved, but computation and control complexity become high
Solution Approach 1:
The patent segments the channel assignment process into two distinct phases: a positioning phase where CPEs are assigned to control channels, and a communication phase where data is transmitted. This segmentation reduces complexity by separating control functions from data transmission functions, allowing each phase to be optimized independently.
Solution Approach 2:
The patent introduces control channels as intermediary channels that mediate between CPEs and data channels. These control channels carry positioning information and control signals, enabling coordinated access to data channels without requiring complex real-time computation during data transmission.
2Productivity
If dynamic channel assignment method is used to allocate channels based on real-time conditions, then channel allocation efficiency is improved, but call processing time increases due to high computation requirements
Solution Approach 1:
The patent performs preliminary channel positioning and control channel assignment before actual data communication begins. By pre-establishing control channel assignments and positioning CPEs in advance, the system eliminates the need for complex real-time channel selection during call setup, significantly reducing call processing time.
3Device complexity
If fixed channel assignment method is used to simplify control, then control complexity is reduced, but channel allocation cannot adapt to changing business conditions and user distribution
Solution Approach 1:
The patent implements a dynamic positioning mechanism where CPEs can be reassigned to different control channels based on real-time conditions such as user distribution and channel availability. This dynamic adjustment capability allows the system to adapt to changing business conditions while maintaining relatively simple control logic through the two-phase approach.

AI summary
The present disclosure is applied to the field of communications, and provides a channel assignment, acquisition method and system, the assignment method including: selecting at least one idle channel from idle channels of a multi-channel sharing system as a control channel; sending an idle signal to the control channel, the idle signal identifying that the control channel is a control channel for a customer premise equipment (CPE) to be positioned therein in a preset positioning manner; and upon receipt of a communication request from a CPE positioned to the control channel, assigning the control channel to the CPE. The present disclosure, by selecting one idle channel as a control channel, positioning a CPE to the control channel after the CPE scans the control channel, and conducting communication through the control channel, can not only achieve dynamic assignment of the channel, but also make the amount of computation of the dynamic assignment small and control complexity of the dynamic assignment lower.
