ASP Session Management for Wi-Fi Direct Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi Direct technology lacks interoperability between services and applications from different vendors, leading to inconsistencies and complexities in Peer-to-Peer connectivity, which affects the management of Application Service Platform (ASP) sessions.
Innovation Solution
Implementing an ASP session management system that uses a unique identifier for each ASP-session, including a combination of a session MAC address and a session identifier, and provides a reason field in messages to close or reject sessions, allowing for improved interoperability and consistency in service management across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wi-Fi Direct technology is used to provide Peer-to-Peer connectivity, then device-to-device connection is enabled, but interoperability between services and applications from different vendors deteriorates
Solution Approach 1:
The patent introduces an Application Service Platform (ASP) as an intermediary layer between services and applications. The ASP manages ASP-sessions that coordinate communication between services and applications from different vendors, enabling interoperability while maintaining reliable service delivery through standardized session management protocols
Solution Approach 2:
The ASP-session management mechanism provides universal functionality across different vendors and services. By using common session identifiers, rejection reason codes, and standardized message formats, the system enables any service to communicate with any application through a unified interface, achieving both interoperability and reliability
2Ease of operation
If Wi-Fi Direct P2P topology is used, then direct device connection is achieved, but complexity of the P2P topology increases
Solution Approach 1:
The patent extracts the complexity management function from the P2P connectivity layer and places it in the ASP-session management layer. The ASP handles topology complexity through centralized session tracking and coordination, while the underlying Wi-Fi Direct connection remains simple and direct
Solution Approach 2:
The system segments the connection management into distinct components: Wi-Fi Direct handles the physical/link layer connectivity, while ASP-sessions handle the application layer coordination. This segmentation allows each component to optimize its function independently, simplifying the overall system operation
3Adaptability or versatility
If ASP-session management with unique identifiers is implemented, then interoperability is improved, but message processing complexity increases
Solution Approach 1:
The patent uses parameter changes in the form of standardized rejection reason codes and session identifier formats to improve interoperability. By defining specific parameter values for different rejection scenarios (e.g., service unavailable, session already exists), the system achieves clear messaging without excessive processing complexity

AI summary
Some demonstrative embodiments include apparatuses, systems and/or methods of managing an Application Service Platform (ASP) session. For example, an apparatus may include a first ASP to communicate with a second ASP via a wireless Peer-to-Peer (P2P) connection over a P2P link to manage an ASP-session between a first device including the first ASP and a second device including the second ASP. The first ASP may communicate with the second ASP a message to close the ASP-session, the message including a reason field including an indication of a reason for closing the ASP-session.
