Mobile Device WLAN Radio Peer-to-Peer Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in peer-to-peer data transfer over wireless local area network (WLAN) due to low data transfer speeds and difficulty in reestablishing connections, as the WLAN radio equipment scans for and connects to configured networks automatically, interfering with user-desired connections and consuming battery resources.
Innovation Solution
Preventing the mobile device from connecting to configured networks during data transfer by disabling them and allowing reconnection only after the transfer is complete, enabling faster data transfer and reduced battery drain by maintaining exclusive focus on the peer-to-peer connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the WLAN radio equipment automatically scans for and connects to configured networks, then the device maintains connectivity to available networks, but data transfer speed decreases and battery power is consumed unnecessarily
Solution Approach 1:
The patent extracts the automatic network scanning and connection functionality from the WLAN radio equipment during peer-to-peer data transfer operations. By preventing the radio equipment from scanning for and connecting to configured networks during data transfer, the system eliminates unnecessary energy consumption and interference with the primary data transfer task, thereby improving both data transfer speed and battery efficiency
Solution Approach 2:
The patent dynamically adjusts the behavior of the WLAN radio equipment based on the operational state. During peer-to-peer data transfer, the radio equipment is configured to exclude configured networks from scanning and connection attempts. After data transfer completion, the restriction is removed and normal network scanning and connection behavior is restored. This dynamic adjustment optimizes performance for the active task while maintaining general connectivity capabilities
2Productivity
If the WLAN radio equipment performs multiplexing between connections, then the device maintains multiple network connections, but data transfer speed decreases
Solution Approach 1:
The patent segments the network connection management into distinct operational modes: peer-to-peer data transfer mode and general network connectivity mode. During peer-to-peer data transfer, the system exclusively maintains the peer-to-peer connection and prevents multiplexing with other network connections. This segmentation ensures that radio resources are dedicated to the primary data transfer task, maximizing data transfer speed without permanently sacrificing the ability to maintain multiple connections when needed
3Reliability
If the radio equipment scans for networks based on desirable radio connectivity conditions, then the device maintains optimal network connectivity, but peer-to-peer connection reestablishment becomes difficult
Solution Approach 1:
The patent applies preliminary action by pre-configuring the WLAN radio equipment to exclude configured networks from scanning and connection attempts during the entire peer-to-peer data transfer operation, including during any connection interruptions. This preliminary restriction prevents the radio equipment from being diverted to other networks, ensuring that when the peer-to-peer connection is lost, the device is already positioned to quickly reestablish the original peer-to-peer connection without needing to scan for or evaluate other networks, thereby both maintaining connection stability and enabling quick reestablishment

AI summary
A disclosed method includes preventing a first mobile device from connecting to configured networks having connectivity information stored in a configured networks list stored in memory of the first mobile device, establishing a peer-to-peer connection with a second mobile device, performing a data transfer from the first mobile device to the second mobile device over the peer-to-peer connection while continuing to prevent the first mobile device from connecting to the configured networks, and enabling the first mobile device to connect to the configured networks after completion of the data transfer.
