Multiple Connection Identifier Selection for Wireless Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad-hoc peer to peer wireless communications systems without centralized control, efficiently allocating air link resources is challenging due to varying traffic needs and interference concerns, leading to inefficient use of resources and wastage.
Innovation Solution
The system allows multiple connection identifiers with different priorities to be associated with a single connection, enabling devices to select and use connection identifiers based on current traffic requirements, optimizing resource usage and reducing interference.
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 is simple and uniform, but resource usage efficiency deteriorates due to varying traffic needs of different connections
Solution Approach 1:
The patent segments air link resources by creating multiple connection identifiers (CIDs) with different priorities. Each CID corresponds to a specific priority level, allowing the system to divide the single shared resource pool into prioritized segments. This enables high-priority traffic to secure dedicated resources while low-priority traffic uses remaining resources, resolving the contradiction between uniform allocation simplicity and efficient resource usage.
Solution Approach 2:
The patent applies local quality by assigning different priority levels to different connection identifiers based on specific traffic requirements. Each CID carries local quality attributes (priority levels) that match the specific needs of particular connections. This allows the system to provide differentiated resource allocation tailored to local traffic characteristics rather than applying uniform allocation globally.
2Productivity
If multiple connection identifiers with different priorities are assigned to a single connection, then resource allocation efficiency improves, but device complexity increases due to multiple identifier management
Solution Approach 1:
The patent makes connection identifiers multi-functional by designing each CID to serve multiple purposes: identification, priority indication, and resource allocation signaling. A single CID structure encapsulates both the connection identity and its priority level, allowing the same identifier system to perform multiple functions simultaneously. This reduces the need for separate management mechanisms and mitigates the complexity increase from having multiple identifiers.
3Productivity
If centralized control is used to allocate air link resources, then resource allocation is efficient and coordinated, but system complexity increases and peer to peer autonomy is reduced
Solution Approach 1:
The patent implements self-service by enabling wireless terminals to autonomously select and use appropriate connection identifiers based on their traffic requirements without centralized control. Each terminal independently manages its CIDs and automatically prioritizes its own traffic by selecting the appropriate CID for transmission. This distributed self-service approach achieves efficient resource allocation without requiring complex centralized control systems.
4Productivity
If connection identifiers are reused in adjacent regions, then air link resource utilization improves, but interference levels increase
Solution Approach 1:
The patent applies dynamics by making connection identifier usage dynamic and adaptable to local conditions. Terminals dynamically select which CIDs to use based on current traffic requirements and local interference conditions. The system can adaptively adjust CID selection and priority assignments in response to changing environmental conditions, allowing efficient resource reuse while managing interference through flexible, context-dependent decisions rather than fixed allocation rules.

AI summary
Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A peer to peer connection holds a set of multiple connection identifiers for a plurality of successive traffic slots. Corresponding to a particular traffic slot, each of the connection identifiers in the set of connection identifiers has a different priority. Short term traffic needs are considered in the use of the multiple connection identifiers being held. For example, a communications device, corresponding to a peer to peer connection which is associated with a plurality of connection identifiers having different priorities, considers the amount and/or latency requirements of data to be transmitted at any given time when selecting which connection identifier to use when transmitting a traffic transmission request for a traffic segment which is in contention.
