Access Channel Timer for Wireless Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the limited number of access channels available at each access node leads to inefficient allocation, as channels are often reserved for inactive devices, reducing availability for other devices that need them, especially during periods of communication inactivity.
Innovation Solution
Implementing an access channel timer that starts upon receiving a call request, allowing the access node to allocate the channel only if a positive response is received before the timer expires, thereby releasing the channel if the request is negative or if no communication occurs, ensuring it is available for other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access channels are allocated to wireless devices that may become inactive, then channel allocation reliability is improved, but channel availability for other devices deteriorates
Solution Approach 1:
The patent implements dynamic channel allocation where the access node monitors communication activity on each channel and reassigns channels from inactive devices to active devices in real-time, transforming the static allocation into a dynamic system that adapts to changing network conditions
Solution Approach 2:
The access node continuously monitors communication activity on allocated channels and uses this feedback information to determine when to reassign channels, creating a closed-loop control system that adjusts channel allocation based on actual usage patterns
2Stability of the object's composition
If access channels are reserved for devices during inactivity periods, then connection stability is improved, but channel utilization efficiency deteriorates
Solution Approach 1:
The access node periodically monitors communication activity on each allocated channel and reassigns channels at regular intervals or when inactivity thresholds are met, implementing a periodic review mechanism that balances connection stability with resource efficiency
3Productivity
If the number of access channels is increased to meet demand, then channel availability is improved, but system complexity and cost deteriorate
Solution Approach 1:
The patent merges the functions of channel allocation, monitoring, and reassignment into a single integrated system at the access node, consolidating multiple operations into one coordinated process that manages all access channels efficiently without requiring additional infrastructure

AI summary
In a communication system, a wireless access node receives an access request from a wireless communication device. In response, the access node starts an access timer and transfers signaling to the communication system indicating the access request. If the access timer expires before a response to the signaling is received, then the access node provides the wireless communication device with wireless access to the communication system. The access node receives the response to the signaling. If the response is negative and is received before the access timer expires, then the access node denies the access request. If the response is negative and is received after the access timer expires, then the access node terminates the wireless access to the communication system for the wireless communication device.
