Base Station Dynamic Channel Selection

Solution Overview

Problem

Current communication systems face rigidity in managing shared communication channels, requiring frequent intervention from control facilities for reallocation, which can be inefficient due to hardware and software resource management constraints and delays in signaling.

Innovation Solution

A method where a base station dynamically selects and indicates shared communication channels to terminals without control facility intervention, using a list of shared channels allocated by the control facility, allowing quasi-autonomous choice and optimal resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the control facility systematically intervenes to reallocate communication channels, then channel allocation reliability is improved, but system flexibility and response speed deteriorate due to signaling delays

Engineering Contradiction:

Improvechannel allocation reliabilityVSAvoidsystem flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments channel management into two parts: the control facility maintains the master list of available channels (ensuring reliability), while the base station independently selects and assigns specific channels from this list to terminals (enabling flexibility). This segmentation allows each entity to operate autonomously within its domain without requiring continuous control facility intervention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control facility performs preliminary action by pre-configuring and distributing the complete list of available shared channels to base stations before actual communication sessions begin. This preliminary setup enables base stations to autonomously make channel selection decisions during runtime without needing to contact the control facility for each individual allocation, thus improving response speed while maintaining reliability through the pre-approved channel list.

Inventive Principle:

Principle #10Preliminary action

2Speed

If the base station autonomously selects shared channels, then system response speed is improved, but control facility authority and coordination deteriorate

Engineering Contradiction:

Improvechannel assignment speedVSAvoidcoordination complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The control facility performs preliminary action by pre-configuring and distributing the complete list of available shared channels to base stations before actual communication sessions begin. This preliminary setup enables base stations to autonomously make channel selection decisions during runtime without needing to contact the control facility for each individual allocation, thus improving response speed while maintaining reliability through the pre-approved channel list.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where base stations report their channel selection decisions and terminal assignments back to the control facility. This feedback loop allows the control facility to maintain awareness of channel usage patterns and system state, enabling it to update and redistribute channel lists as needed while preserving base station autonomy in real-time selections.

Inventive Principle:

Principle #23Feedback

3Reliability

If the terminal is assigned specific channels by the control facility, then channel management reliability is improved, but resource utilization efficiency deteriorates due to rigid allocation

Engineering Contradiction:

Improvechannel management reliabilityVSAvoidresource utilization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments channel management into two parts: the control facility maintains the master list of available channels (ensuring reliability), while the base station independently selects and assigns specific channels from this list to terminals (enabling flexibility). This segmentation allows each entity to operate autonomously within its domain without requiring continuous control facility intervention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transforms the channel allocation system from a static, control-facility-centric model to a dynamic model where base stations can flexibly select and reassign channels based on real-time system conditions and terminal requirements. The channel list serves as a dynamic resource pool that base stations can adaptively manage, allowing channels to be reassigned to different terminals as needs change without requiring control facility reconfiguration.

Inventive Principle:

Principle #15Dynamics

AI summary

A control method allocates to a base station, at a control member of the base station, a list of channels shared by several terminals containing several sets of shared channels. For a communication session between the base station and a specific terminal, the method indicates to the terminal the list of shared channels allocated to the base station. At the base station, the method selects for the terminal one of the sets of shared channels, and independently of the control member, indicates the selected set to the terminal via a dedicated channel.
