Group Owner Intent Value Negotiation in Wi-Fi P2P Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for efficient control of connectivity in wireless communication devices when negotiating a group owner in Wi-Fi Peer-to-Peer (P2P) networks, especially in determining the group owner intent value for establishing connections to external networks like the Internet.
Innovation Solution
A wireless device identifies whether it is operating on a home or non-home network and sets its group owner intent value accordingly, sending this value to another device to determine the group owner for establishing a P2P network connection to an external network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device always sets high group owner intent value to become group owner, then the device can control external network connectivity, but it increases device complexity and energy consumption
Solution Approach 1:
The patent dynamically changes the group owner intent value parameter based on network type (home vs. non-home). When on a home network, the device sets a high intent value to become group owner and control connectivity. When on a non-home network, it sets a low intent value to avoid becoming group owner, thus avoiding unnecessary complexity and energy consumption while maintaining reliable connectivity control when needed.
2Reliability
If a device sets high group owner intent value to ensure external network access, then connectivity reliability improves, but energy consumption increases
Solution Approach 1:
The patent dynamically adjusts the group owner intent value parameter based on the detected network type. On home networks, the device sets a high intent value to ensure it becomes group owner and maintains reliable external connectivity. On non-home networks, it sets a low intent value to avoid the energy-intensive role of group owner, thus reducing energy consumption while preserving connectivity reliability where needed.
3Reliability
If a device becomes group owner on non-home networks, then it can provide external connectivity, but it loses adaptability to network environment
Solution Approach 1:
The patent changes the group owner intent value parameter based on network environment detection. On home networks, the device sets high intent to become group owner and provide connectivity. On non-home networks, it sets low intent to adapt to the existing network structure, demonstrating environmental adaptability while ensuring connectivity provision where appropriate.

AI summary
Techniques in a wireless device for use in negotiating a group owner with another wireless device for establishing a wireless peer-to-peer (P2P) network having a connection to an external network are described. The wireless device identifies whether it is operating for communications via a home network or a non-home network. The wireless device sets its group owner intent value to an increased value when it is identified to be operating for communications via the home network, or to a decreased value when it is identified to be operating for communications via the non-home network. The wireless device then sends to the other wireless device a message which includes the group owner intent value for the wireless device. Once the group owner is selected, the wireless device will connect with the other wireless device for establishing the wireless P2P network having the connection to the external network.
