P2P Group Owner Re-negotiation for Mobile Terminal Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Peer-to-Peer (P2P) wireless LAN connections in mobile communication terminals, existing technologies face limitations in resource data rate, security, and power consumption, particularly in scenarios where a terminal outside the connection area attempts to connect with others, as the group owner/slave terminal structure restricts connectivity beyond the slave terminal's range.
Innovation Solution
A method and apparatus for P2P connection in mobile communication terminals that detect a new terminal's connection attempt, determine the terminal's role as either slave or group owner, and re-negotiate the group owner when necessary, allowing for connectivity by transmitting signals to facilitate the inclusion of new terminals in the P2P network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the group owner/slave terminal structure is used in P2P connection, then the P2P connection can be established between terminals, but a terminal outside the connection area cannot connect with the P2P network even though it is within the slave terminal's range
Solution Approach 1:
The patent implements dynamic group owner re-negotiation where the group owner role can be transferred between terminals. When a new terminal attempts to join the P2P network, the system dynamically determines whether to re-negotiate the group owner role to allow the new terminal to connect, thereby making the connection area flexible and adaptive rather than fixed to the original slave terminal's range.
Solution Approach 2:
The patent changes the parameter of group owner status from a fixed assignment to a dynamic parameter that can be re-negotiated. By allowing the group owner role to be transferred based on connection requirements, the system expands the effective connection area beyond the original slave terminal's range while maintaining P2P connection functionality.
2Ease of operation
If the P2P discovery procedure is performed to find a P2P terminal, then the terminal can search for connection opportunities, but the connection cannot be established when the new terminal is outside the existing connection area
Solution Approach 1:
The patent implements a feedback mechanism where the slave terminal notifies the group owner terminal about new connection attempts. This feedback loop ensures that when a new terminal attempts to join, the system receives information about the attempt and can respond by initiating group owner re-negotiation, thereby improving the reliability of connection establishment for terminals outside the original connection area.
Solution Approach 2:
The patent performs preliminary group owner re-negotiation before the actual connection is established. By proactively determining whether the group owner role should be transferred when a new terminal attempts to join, the system prepares the necessary connection parameters in advance, ensuring that the connection can be successfully established even for terminals outside the original connection area.
3Productivity
If the slave terminal detects a P2P connection attempt, then the terminal can respond to connection requests, but the connection is blocked when the attempting terminal is outside the connection area
Solution Approach 1:
The patent makes the group owner status dynamic by allowing re-negotiation when new terminals attempt to join. This dynamic adjustment enables the network to adapt to expanding connectivity requirements while maintaining efficient response to connection attempts, as the system can quickly determine whether to transfer the group owner role based on the new terminal's location and connection needs.
Solution Approach 2:
The patent introduces the group owner terminal as an intermediary that coordinates connection requests from new terminals. When a slave terminal detects a connection attempt, it notifies the group owner, which then mediates the decision to transfer the group owner role. This intermediary mechanism enables efficient connection responses while facilitating network expansion to include terminals outside the original connection area.

AI summary
An apparatus and a method for Peer-to-Peer (P2P) connection using a wireless Local Area Network (LAN) in a mobile communication terminal are provided. The method includes detecting a P2P connection attempt of a new terminal not connected to P2P communication, during P2P communication with at least one terminal, determining whether the mobile communication terminal operates as a slave terminal or a group owner in the P2P connection, and when the mobile communication terminal operates as the slave terminal, transmitting a signal indicating that the P2P connection attempt of the new terminal is detected, to a terminal operating as the group owner in the P2P connection.
