Multiple Connection Identifier Allocation for Wireless Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In peer-to-peer wireless communications systems, especially ad-hoc networks without centralized control, efficiently allocating air link resources is challenging due to varying traffic needs and interference concerns, leading to inefficient resource allocation and wastage.
Innovation Solution
The method involves associating multiple connection identifiers with a single connection between wireless terminals, allowing for differentiated quality of service by assigning different numbers of connection identifiers based on quality of service levels, traffic data rates, and priority, and using orthogonal MAC IDs to prioritize and allocate air link resources in a distributed manner through handshake signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the same fixed amount of air link resources is allocated to each connection, then resource allocation simplicity is maintained, but resource utilization efficiency deteriorates due to mismatched traffic needs
Solution Approach 1:
The patent segments air link resources by associating multiple connection identifiers with a single connection. Each connection identifier can be mapped to different resource units (e.g., OFDM tone-symbols in traffic transmission request resources), allowing differentiated resource allocation. High-priority connections receive more connection identifiers and thus more resources, while low-priority connections receive fewer, resolving the contradiction between efficiency and simplicity.
Solution Approach 2:
The patent applies local quality by assigning different numbers of connection identifiers to different connections based on their specific traffic needs, priority levels, and QoS requirements. Each connection receives a customized resource allocation rather than a uniform distribution, optimizing resource utilization for each local connection while maintaining overall system efficiency.
2Reliability
If multiple connection identifiers are assigned to high-priority connections, then quality of service differentiation is improved, but resource allocation complexity increases in distributed peer-to-peer networks
Solution Approach 1:
The patent enables self-service by allowing wireless terminals to autonomously select and negotiate connection identifiers with their peers through distributed handshake signaling. Terminals independently determine appropriate resource allocations based on local QoS requirements and traffic conditions, eliminating the need for centralized resource management while achieving effective QoS differentiation.
Solution Approach 2:
The patent incorporates feedback mechanisms where wireless terminals exchange information about their QoS requirements, traffic patterns, and resource needs during connection establishment and maintenance. This feedback enables terminals to dynamically adjust connection identifier assignments and resource allocations to match actual service requirements, achieving QoS differentiation through distributed decision-making.
3Productivity
If connection identifiers are reused across adjacent regions in peer-to-peer networks, then resource utilization efficiency is improved, but interference levels increase without centralized coordination
Solution Approach 1:
The patent applies dynamics by making connection identifier assignments and resource allocations adaptive to changing network conditions, traffic patterns, and interference environments. Terminals dynamically adjust their resource usage based on real-time observations of network state, allowing efficient resource reuse in adjacent regions while adapting to varying interference conditions without centralized coordination.

AI summary
Methods and apparatus related to a peer to peer wireless communications system supporting the association of multiple connection identifiers with a single connection between a pair of wireless terminals are described. A differentiated quality of service is supported by assigning different numbers of connection identifiers to different connections. The number of connection identifiers assigned to a wireless terminal pair for a connection is a function of one of: data rate, priority information, and quality of service information. Being allocated a higher number of connection identifiers results in being allocated a higher number of traffic transmission request resources, thus increasing the likelihood that the connection is permitted to use a traffic transmission segment. The allocation of connection identifiers is performed in a distributed manner in which handshake signaling occurs between a wireless terminal pair seeking to establish a connection, e.g., as part of a multi-step paging scheme.
