Solution Overview

Problem

Users cannot determine prior to connecting to a hotspot whether it supports specific services like VPN, VoIP, or video streaming, leading to potential service unavailability and unnecessary connection costs.

Innovation Solution

A method and apparatus that enable a user device to determine an access point's service capabilities by sending a test message with an information identifier before connecting, allowing the device to decide whether to connect based on the access point's support for specific services or connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users connect to hotspots without prior service capability verification, then connection establishment is fast and simple, but users may incur unnecessary costs and experience service unavailability

Engineering Contradiction:
Improveservice availabilityVSAvoidconnection establishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary service capability verification by sending probe requests containing information element identifiers before establishing full connections. This allows users to determine access point service capabilities in advance, avoiding unnecessary connections and ensuring service availability before committing to a connection.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If hotspots block certain traffic types like UDP without resource allocation control, then resource management is simplified, but service capabilities are reduced

Engineering Contradiction:
Improveresource management complexityVSAvoidservice capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary probe request mechanism that allows service capability verification without requiring full resource allocation or complex traffic management. The probe requests act as a mediator between users and hotspots, enabling service capability determination with minimal resource consumption and without requiring complex resource allocation control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for determining access point service capabilities may include identifying, at a mobile terminal, an access point to which the mobile terminal is capable of establishing a connection, determining, prior to authentication between the mobile terminal and the access point, whether the access point supports a particular service or connection, and enabling a connection determination to be made at the mobile terminal regarding whether to connect to the access point based on whether the access point supports the particular service or connection. A corresponding computer program product and apparatuses are also provided.
