Solution Overview

Problem

Current wireless communication systems face inefficiencies in service discovery, as devices must connect and authenticate to access point (AP) to discover available services, which consumes resources and time, and may not efficiently determine if a desired service is offered by the AP, leading to repeated connection attempts if the service is not found.

Innovation Solution

The system allows APs to advertise available services without device connection, enabling devices to determine service availability before connecting, and implements a service discovery process that includes authentication status-based publication rules to securely and efficiently provide service information to connected or unconnected devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If devices connect and authenticate to access point to discover services, then service discovery can be performed, but resource consumption and connection overhead increase

Engineering Contradiction:
Improveservice discovery reliabilityVSAvoiddevice energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The access point performs preliminary service information advertisement and publishing before any device connection or authentication occurs. Service information is made available in advance through wireless transmissions, allowing devices to discover services without establishing connections, thereby eliminating the need for authentication overhead while maintaining reliable service discovery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The service discovery function is extracted from the connection establishment process. Instead of requiring devices to connect and authenticate to discover services, the service information is separated and transmitted independently through advertisement messages, allowing discovery to occur as a standalone operation before connection is needed.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If devices connect and authenticate to access point to discover services, then service information can be obtained, but time is consumed for connection establishment

Engineering Contradiction:
Improveservice discovery reliabilityVSAvoidconnection establishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Service information is published and advertised by the access point in advance, before any device connection attempts. This preliminary publication of service information allows devices to immediately discover available services without spending time on connection establishment and authentication procedures.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If access point advertises services without device connection, then resource consumption is reduced, but security control over service information becomes challenging

Engineering Contradiction:
Improveservice discovery efficiencyVSAvoidsecurity management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Different service information is provided to different device categories. The access point applies publication rules that differentiate between authenticated and unauthenticated devices, allowing services to be advertised with appropriate security restrictions. Some service information is made publicly available while other information is restricted to authenticated devices only, creating local quality variations in information access.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The publication rules are dynamically applied based on device authentication status. The access point adapts the level of service information disclosure according to whether the requesting device is authenticated, allowing flexible security control that responds to the current state of device authentication without requiring complex pre-configuration.

Inventive Principle:
Principle #15Dynamics

AI summary

Systems, methods, and apparatuses for efficient infrastructure service discovery with security are disclosed. In one aspect, systems and methods for advertising services available via an access point without requiring a device to connect for discovery are described. This may allow devices to determine, prior to establishing a connection with an access point, whether a desired service is offered. Further description of publication rules is provided. Service providers can use the publication rules to identify service information which may be discovered by devices based on device authentication status or other factors to allow controlled, secure discovery of the service information.
