Solution Overview

Problem

Current wireless communication systems face inefficiencies in data transmission due to complex authentication and association procedures, which can be cumbersome and require unnecessary steps, especially in Neighbor Awareness Networking (NAN) devices.

Innovation Solution

A method for transmitting data in a wireless communication system that simplifies authentication and association by incorporating necessary attribute information into a service discovery frame, allowing for streamlined data exchange and encryption using hash data for service IDs, thereby reducing procedural overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex authentication and association procedures are used for data transmission in NAN devices, then security and proper device identification are ensured, but transmission efficiency and procedural simplicity deteriorate

Engineering Contradiction:
Improveauthentication securityVSAvoiddata transmission efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines authentication attributes and association attributes into a single service discovery frame. Instead of exchanging separate authentication frames and association frames in sequential steps, the invention merges both authentication information (such as authentication type, authentication ID) and association information (such as association type, association ID) into one unified frame structure, allowing NAN devices to complete both authentication and association procedures simultaneously during service discovery, thereby eliminating redundant procedural steps and improving transmission efficiency while maintaining security requirements

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple separate frames (authentication frame and association frame) are exchanged for data transmission, then proper authentication and association are achieved, but procedural overhead and complexity increase

Engineering Contradiction:
Improvedevice identification accuracyVSAvoidprocedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges multiple separate frame exchange procedures into a single service discovery frame exchange. The unified frame structure contains both authentication attributes (authentication type, authentication ID, authentication authority) and association attributes (association type, association ID), allowing devices to complete what would traditionally require separate authentication frame and association frame exchanges in a single integrated procedure, thereby reducing procedural complexity while maintaining proper device identification and authentication

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The service discovery frame is enhanced to serve multiple functions simultaneously: it performs service discovery, authentication verification, and association establishment all in one frame exchange. This multi-functional approach eliminates the need for separate dedicated frames for each function, reducing the overall number of frames that need to be exchanged and processed while ensuring reliable device identification and connection establishment

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If traditional authentication and association procedures are followed, then secure data transmission is established, but unnecessary steps and time consumption increase

Engineering Contradiction:
Improvedata transmission securityVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention performs authentication and association actions preliminarily by embedding authentication attributes and association attributes into the service discovery frame that is exchanged during the initial service discovery phase. This allows authentication and association to be completed before actual data transmission begins, so that when data needs to be transmitted, the security framework is already in place and devices can immediately commence efficient data exchange without re-performing authentication or association steps

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By merging authentication procedures and association procedures into a single integrated frame exchange during service discovery, the invention eliminates the sequential time consumption of separate authentication frame exchange followed by separate association frame exchange. The unified approach allows both authentication and association to be processed concurrently or in a single streamlined sequence, significantly reducing the total time required to establish secure data transmission while maintaining all necessary security checks

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present specification relates to a method for transmitting data by a first neighbor awareness networking (NAN) device in a wireless communication system. The method for transmitting data may comprise the steps of: performing a service discovery for a first service with a second NAN device through a service discovery frame (SDF); and exchanging data for the first service with the second NAN device on the basis of the performed service discovery. Here, when at least one of authentication and association is required in transmitting the data for the first service, attribute information which is required for the data transmission among information on authentication attributes and information on association attributes may be included in the service discovery frame.
