Solution Overview

Problem

There is a need for an efficient method to update and manage the proxy service in a wireless communication system, particularly for neighbor awareness networking (NAN) proxy clients and servers, to ensure timely and efficient communication while minimizing power consumption.

Innovation Solution

The method involves a NAN proxy client transmitting a Proxy Registration Request to an NAN proxy server, receiving a Proxy Registration Response, and periodically sending a Proxy Registration Update Request, which includes Time to Live (TTL) information, with the update period set to be shorter than the TTL, allowing for proactive service updates and efficient power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the proxy service is updated frequently to maintain service availability, then service reliability is improved, but power consumption increases

Engineering Contradiction:

Improveservice availabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The NAN proxy client performs preliminary actions by setting up the proxy service registration with the NAN proxy server in advance, including configuring the TTL value that determines service validity duration. This preliminary configuration allows the system to maintain service availability without frequent updates, thereby reducing power consumption while ensuring reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements periodic action through the TTL-based refresh mechanism. The NAN proxy client periodically updates the proxy service registration before the TTL expires, rather than continuously or frequently. This periodic update approach maintains service availability while minimizing the number of transmissions, thus reducing power consumption compared to more frequent update schemes.

Inventive Principle:

Principle #19Periodic action

2Productivity

If the update period is set shorter than TTL for proactive updates, then service management efficiency is improved, but communication overhead increases

Engineering Contradiction:

Improveservice management efficiencyVSAvoidcommunication overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

By setting the update period shorter than the TTL value, the system performs preliminary updates before the service actually expires. This proactive approach improves service management efficiency by preventing service interruptions while controlling communication overhead through planned, non-excessive updates.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs feedback mechanisms where the NAN proxy client monitors the TTL value and adjusts update timing accordingly. The client receives feedback from the NAN proxy server about service registration status and uses this information to determine when updates are necessary, optimizing the balance between management efficiency and communication overhead.

Inventive Principle:

Principle #23Feedback
