Priority-Based Data Channel Allocation in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently allocating data channels, particularly during high demand situations, where priority is needed for emergency or high-priority communications, leading to delays and resource scarcity.
Innovation Solution
A priority access system that determines priority scores for data channel requests based on user-specific and service-type priorities, enabling preemption or queuing of existing channels to allocate resources effectively, ensuring timely and reliable communication for critical services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data channels are allocated on a first-come-first-served basis, then network resource utilization is maximized, but high-priority communications experience delays and service quality deteriorates
Solution Approach 1:
The patent changes the allocation parameter from simple temporal order (first-come-first-served) to a composite priority score that incorporates multiple factors including QoS requirements, user subscription level, and current network conditions. This allows the system to differentiate between various communication types and allocate resources accordingly, improving service quality for high-priority communications while maintaining reasonable utilization through structured decision-making
Solution Approach 2:
The patent introduces an intermediary priority scoring mechanism that mediates between resource availability and communication requests. Rather than directly allocating channels based on simple queue position, the system uses priority scores as an intermediary to evaluate and rank requests, enabling nuanced resource allocation that balances multiple competing factors without requiring complex real-time negotiations
2Reliability
If preemption is enabled for high-priority requests, then service reliability improves, but network stability deteriorates due to frequent channel reallocation
Solution Approach 1:
The patent implements dynamic preemption thresholds that adjust based on current network conditions and the severity of QoS requirements. Rather than applying preemption uniformly, the system dynamically adapts the aggressiveness of channel reallocation based on factors such as network congestion level, the criticality of the high-priority request, and the importance of existing connections, thereby balancing service reliability with network stability
Solution Approach 2:
The patent applies preemption selectively rather than uniformly across all channels and users. The priority scoring mechanism evaluates each request locally based on its specific QoS requirements and compares it against existing allocations, enabling preemption only where necessary and appropriate. This localized approach minimizes unnecessary reallocations while still guaranteeing resources for critical communications
3Adaptability or versatility
If multiple priority levels are implemented, then service differentiation improves, but system complexity increases
Solution Approach 1:
The patent creates a universal priority scoring framework that can accommodate multiple priority levels and service types through a single integrated mechanism. Rather than implementing separate management systems for different service types (voice, data, video, emergency), the system uses a unified priority score calculation that incorporates various QoS parameters, user profiles, and network conditions, enabling service differentiation while simplifying overall system architecture
Solution Approach 2:
The patent segments the priority determination process into distinct calculable factors (QoS requirements, user subscription level, network conditions, request type) that can be independently evaluated and then combined. This segmentation allows the complex priority management to be broken down into manageable components, each with clear rules, reducing overall system complexity while maintaining fine-grained service differentiation capabilities
4Reliability
If data channels are reserved for high-priority communications, then service quality improves, but overall network utilization decreases
Solution Approach 1:
The patent implements partial reservation through priority scoring rather than full static reservation. High-priority communications receive preferential treatment and can preempt lower-priority channels when needed, but the system does not permanently reserve channels, allowing them to be used by lower-priority traffic when high-priority demands are absent. This partial action approach ensures service quality for critical communications while maintaining higher overall network utilization compared to full reservation schemes

AI summary
In an embodiment, an access network (AN) receives a request to allocate a given data channel (e.g., a traffic channel (TCH), Quality-of-Service, an Internet Protocol (IP) address, etc.) to a given wireless communication device (e.g., a call originator, a call target, etc.). The AN determines whether the given data channel is available for allocation to the wireless communication device. If the AN determines the given data channel not to be available for allocation to the wireless communication device, the AN determines a priority score to be associated with the received request. The AN initiates one of a plurality of data channel acquisition procedures (e.g., a preemption procedure, a queuing procedure, etc.) if the determined priority score is above at least one priority score threshold, each of the plurality of data channel acquisition procedures configured to obtain the given data channel in order to service the received request.
