Solution Overview

Problem

In wireless communication networks, especially in neighbor aware networks, devices face challenges in efficiently sharing context information while minimizing power consumption and reducing packet collisions, as advertising services and data can lead to increased power usage and packet collisions.

Innovation Solution

The method involves a device receiving service information from a station, generating a message to indicate its own services, and transmitting it to a remote station, with conditions based on proxy preference numbers and error thresholds, allowing for coordinated service discovery and utilization, and the option to act as a proxy station to reduce advertising overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If devices advertise services and data in wireless networks, then service discovery capability is improved, but power consumption increases

Engineering Contradiction:

Improveservice discovery capabilityVSAvoidpower consumption

Core Design Contradiction:

Difficulty of detecting and measuringVSUse of energy by moving object

Solution Approach 1:

The patent introduces a proxy station as an intermediary that collects and consolidates service information from multiple devices. Instead of each device advertising independently, the proxy station aggregates this information and performs centralized advertising, reducing the total number of advertisement transmissions and thereby lowering power consumption while maintaining service discovery capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges multiple service advertisements into a single consolidated advertisement message. By combining service information from multiple devices into one unified advertisement transmitted by the proxy station, the system reduces the frequency of transmissions and minimizes power consumption while preserving complete service discovery functionality.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of information

If devices advertise services frequently, then service information availability is improved, but packet collisions increase

Engineering Contradiction:

Improveservice information availabilityVSAvoidpacket collisions

Core Design Contradiction:

Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent combines service information from multiple devices into a single consolidated advertisement message transmitted by the proxy station. This merging approach reduces the number of simultaneous transmissions in the network, thereby decreasing packet collisions while ensuring that complete service information remains available to all devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The proxy station acts as an intermediary that collects service information from multiple devices and transmits it through a single coordinated channel. This centralized approach prevents the packet collisions that would occur if multiple devices transmitted advertisements simultaneously, while maintaining full service information availability.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If all devices perform service advertisement, then service coverage is improved, but network overhead increases

Engineering Contradiction:

Improveservice coverageVSAvoidnetwork overhead

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent designates a proxy station as an intermediary to perform centralized service advertisement. This single proxy station represents multiple devices in the network, consolidating their service information into unified advertisements. This approach maintains comprehensive service coverage while significantly reducing network overhead by eliminating redundant advertisements from individual devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The proxy station performs multiple functions: it collects service information from multiple devices, consolidates this information, and transmits unified advertisements on behalf of all represented devices. This multi-functional approach ensures complete service coverage while minimizing network overhead through a single advertising entity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems and methods share context information on a neighbor aware network. A method for communicating data in a wireless communications network is disclosed. The method includes receiving, by a device, a first message from a station, decoding the message to determine service information, the service information identifying a service provided by the station, generating a second message, wherein the second message is generated to indicate the service provided by the station and service information of the device, and transmitting, by the device, the second message to a remote station.
