Unified Multi-Radio Discovery for Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi direct services lack a unified solution for establishing sessions using Neighbor Awareness Networking (NAN), Bluetooth Low Energy (BLE), and Near Field Communication (NFC, as existing protocols do not provide information to set up sessions over peer-to-peer or access point infrastructure, and have limitations such as short packet sizes in BLE.
Innovation Solution
The proposed solution extends Wi-Fi direct discovery mechanisms to incorporate NAN, BLE, and NFC, enabling unified information exchange for setting up data sessions over both peer-to-peer and access point infrastructure links, using service provider information attributes to facilitate connection setup and user intent confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Wi-Fi direct discovery mechanisms are extended to incorporate NAN, BLE, and NFC for unified service setup, then device discovery efficiency and session establishment speed are improved, but device complexity and protocol integration challenges increase
Solution Approach 1:
The patent implements a universal service setup mechanism that works across multiple radio access technologies (Wi-Fi, NAN, BLE, NFC) through a common service provider information attribute structure. The service setup request and response messages are designed to be protocol-agnostic, allowing the same discovery and connection establishment流程 to function across different wireless technologies, thereby improving device discovery efficiency while managing complexity through standardization.
Solution Approach 2:
The patent introduces service provider information attributes as an intermediary layer that mediates between different radio protocols and the application layer service setup process. This intermediary structure standardizes the information exchange format, allowing diverse protocols (NAN, BLE, NFC) to communicate service capabilities and setup requirements through a unified attribute framework, reducing the complexity of direct multi-protocol integration.
2Loss of time
If service provider information attributes are exchanged during discovery phase, then session establishment speed is improved, but data transmission overhead increases
Solution Approach 1:
The patent performs service setup information exchange during the discovery phase, before actual data transmission begins. Service provider information attributes including service setup request and response messages are exchanged preliminarily to establish session parameters, so that when data transmission starts, the session is already configured and ready, reducing establishment time without adding overhead during the actual data transfer phase.
3Adaptability or versatility
If multiple radio protocols (NAN, BLE, NFC) are integrated for service discovery, then adaptability and connectivity options are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent implements dynamic protocol selection and activation based on service requirements and availability. The system can dynamically choose which radio protocol (NAN, BLE, NFC, or Wi-Fi) to use for a given service discovery and setup task, activating only the necessary protocols rather than maintaining all simultaneously, thereby improving adaptability while managing power consumption through selective activation.
