Solution Overview

Problem

Existing Wi-Fi peer-to-peer (P2P) technologies face challenges in efficiently managing multiple simultaneous P2P connections without disrupting existing connections or causing performance degradation due to frequency band limitations and antenna switching.

Innovation Solution

An electronic device is configured to form a second P2P group with a second external device by obtaining group owner (GO) permission while maintaining an existing P2P group, based on the device's role and frequency capabilities, allowing simultaneous execution of multiple P2P services without off-channel operations.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an electronic device forms multiple P2P groups simultaneously using existing Wi-Fi P2P technologies, then the device can connect to multiple external devices, but the connection speed decreases and performance degrades due to frequency band limitations and antenna switching

Engineering Contradiction:

Improveability to form multiple P2P groupsVSAvoidconnection speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent segments the frequency bands into dedicated P2P frequency bands (e.g., 2.4 GHz and 5 GHz) and assigns different P2P groups to different frequency bands. This allows simultaneous P2P connections without frequency conflicts, eliminating the need for antenna switching and maintaining high connection speed across multiple groups

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces frequency band as an additional dimension for P2P group management. By utilizing multiple frequency bands (2.4 GHz, 5 GHz, and potentially 6 GHz), the system can establish multiple P2P groups in parallel without interference, transforming the single-frequency limitation into a multi-frequency advantage

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If an electronic device forms multiple P2P groups simultaneously using existing Wi-Fi P2P technologies, then the device can connect to multiple external devices, but performance degradation occurs due to antenna switching requirements

Engineering Contradiction:

Improveability to form multiple P2P groupsVSAvoidperformance stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments P2P groups across different frequency bands, allowing each group to operate on a dedicated frequency without requiring antenna switching. This segmentation eliminates the performance instability caused by frequent antenna switching and maintains reliable connections across multiple simultaneous P2P groups

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary frequency band selection during P2P group formation, assigning groups to appropriate frequency bands before connection establishment. This preliminary action prevents the need for subsequent antenna switching and ensures stable performance throughout the P2P connection lifecycle

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If an electronic device uses off-channel operations to manage multiple P2P groups, then the device can handle multiple connections, but connection speed decreases and performance degrades

Engineering Contradiction:

Improveability to manage multiple P2P connectionsVSAvoidP2P service execution efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments multiple P2P connections across different frequency bands, allowing each connection to operate independently on its assigned frequency without requiring off-channel operations. This eliminates the productivity loss associated with off-channel switching and enables continuous, efficient data transmission across all P2P groups simultaneously

Inventive Principle:

Principle #1Segmentation

AI summary

An example method of forming a Wi-Fi P2P group of an electronic device includes obtaining information for Wi-Fi P2P connection to a second external electronic device while the electronic device forms a first P2P group with a first external electronic device through a Wi-Fi P2P connection and generating a second P2P group with the second external electronic device by obtaining a group owner (GO) permission while maintaining the first P2P group based on the information and a role of the electronic device in the first P2P group.
