Hybrid Random Planned Channel Allocation for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face performance degradation due to high overhead or latency issues, particularly in the lack of availability of network resources on a priority basis, whether through dedicated control channels or unplanned access methods.
Innovation Solution
A method and apparatus for channel allocation using a combination of random and planned processes, where random events trigger requests for channels, and planned processes evaluate network load and subscriber status to prioritize access based on probabilistic prioritization and payment or status-based services.

Engineering Contradiction Analysis
1Productivity
If completely planned access is used with dedicated control channels, then network resource allocation is improved, but system overhead increases
Solution Approach 1:
The system dynamically adjusts channel allocation based on real-time network conditions and subscriber priority status. High-priority subscribers receive channels through planned processes when network resources are available, while lower-priority subscribers use random access when resources are constrained, creating a flexible hybrid access mechanism that adapts to varying load conditions.
Solution Approach 2:
The invention changes the access parameter from fixed (either purely planned or purely random) to variable based on subscriber priority status and network load. The system monitors network resource availability and dynamically switches between planned and random access modes, optimizing the balance between resource allocation efficiency and system overhead.
2Device complexity
If unplanned access is used by listening for space/time, then system overhead is reduced, but access latency increases
Solution Approach 1:
The system performs preliminary actions by pre-allocating or reserving channels for high-priority subscribers through planned processes before they need access. This ensures that when high-priority traffic arrives, channels are already prepared and immediately available, eliminating the need for time-consuming random access contention and reducing access latency for critical services.
Solution Approach 2:
The access mechanism dynamically adapts based on subscriber priority and network conditions. High-priority subscribers benefit from planned access with pre-prepared channels, while lower-priority subscribers use random access only when necessary, creating a dynamic system that minimizes overall latency for critical services while maintaining low overhead.
3Device complexity
If network resources are not allocated on a priority basis, then system simplicity is maintained, but performance degrades
Solution Approach 1:
The system segments subscribers into different priority classes (high-priority and low-priority) and applies different access mechanisms to each segment. High-priority subscribers receive dedicated planned access with guaranteed channel availability, while low-priority subscribers use standard random access. This segmentation allows the system to maintain overall simplicity while providing prioritized performance for critical services without complicating the entire system.

AI summary
Wireless communication traffic channels are allocated based on random plus planned processes. A request for a traffic channel is sent on a random traffic channel that is not a dedicated random access channel. A determination is made whether to allocate a traffic channel based on status of a subscriber that sere the traffic channel request, including determining base on temps of subscription of the subscriber. An implementation at a base station includes receiving the request on a traffic channel making the determination, and assigning either the traffic channel on which the request was received, or another channel. In a user terminal, the user terminal sends the request on a random traffic channel that it is not assigned to, and receives a traffic channel allocation, or an indication that no channel is available.
