NAN Proxy Server Registration for Wireless Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack an efficient method for a neighbor awareness networking (NAN) device to serve as a proxy server and client, particularly in performing data transmission and power saving functions within a wireless communication system.
Innovation Solution
A method and apparatus for a NAN proxy client to register with a NAN proxy server, involving transmitting a subscribe message, receiving a publish message, and sending a proxy registration request, with the NAN proxy client being registered upon receiving a proxy registration response, and optionally waking based on a discovery window interval, allowing the NAN proxy server to perform data transmission and power saving functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a NAN device performs continuous data transmission and service discovery, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent introduces a proxy server as an intermediary between the NAN proxy client and other NAN devices. The proxy server handles service discovery, data transmission, and communication management on behalf of the client, allowing the client to enter low-power states while maintaining communication reliability through the proxy's continuous operation.
Solution Approach 2:
The proxy server performs service discovery and establishes communication channels in advance before the client needs to access services. This preliminary action allows the client to wake up from low-power states and immediately access pre-established communication channels, maintaining reliability while reducing power consumption during idle periods.
2Adaptability or versatility
If a NAN device performs frequent service discovery and data transmission, then service availability is improved, but device complexity increases
Solution Approach 1:
The proxy server acts as an intermediary that handles complex service discovery and data transmission operations, reducing the computational burden and complexity of the NAN proxy client device while maintaining service availability through the proxy's capabilities.
3Speed
If a NAN device remains in active state for continuous operation, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The NAN proxy client operates in periodic cycles, alternating between active states for data transmission and low-power states for saving energy. The proxy server manages these periodic operations, ensuring that data transmission occurs at high speed when the client is active while minimizing power consumption during idle periods.

AI summary
The present specification relates to a method for a NAN proxy client to perform registration to a NAN proxy server in a wireless communication system. The method for a NAN proxy client to perform registration to a NAN proxy server may comprising: transmitting a subscribe message regarding proxy service search to the NAN proxy server; receiving a publish message from the NAN proxy server; transmitting a proxy registration request message to the NAN proxy server on the basis of proxy service; and receiving a proxy registration response message on the basis of the proxy registration request message.
