Solution Overview

Problem

Current wireless communication devices face inefficiencies in communicating with multiple networks using different protocols, leading to suboptimal user experience, battery drain, and underutilization of WLAN networks, as they require scanning and manual association processes that increase latency and power consumption.

Innovation Solution

The implementation of multiple wireless transceivers in communication devices that share pre-association data via a transceiver interface, allowing for seamless association with different wireless networks, such as 802.11u and 3GPP, using protocols like ANQP, which reduces latency and power consumption by enabling offline AP selection and avoiding unnecessary scanning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication devices perform scanning and manual association processes to communicate with multiple networks, then the device can establish connections with different wireless networks, but the latency increases and power consumption increases

Engineering Contradiction:

Improveability to communicate with multiple networksVSAvoidlatency

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the first wireless transceiver obtain association information (such as network name, security settings, and connection parameters) before the second transceiver needs to associate with the network. This pre-fetched association information is then shared with the second transceiver, eliminating the need for the second transceiver to perform time-consuming scanning and manual association processes, thereby reducing latency while maintaining multi-network adaptability

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

Engineering Contradiction:

Improveability to communicate with multiple networksVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The first wireless transceiver performs association information gathering in advance and stores it locally. When the second wireless transceiver needs to connect to the same network, it retrieves the pre-obtained association information instead of performing new scanning and association procedures, significantly reducing power consumption while maintaining the ability to communicate with multiple networks

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism where the first wireless transceiver acts as a mediator that has already completed the complex association process. The association information obtained by the first transceiver is shared with the second transceiver, allowing the second transceiver to connect without repeating the energy-intensive scanning and manual association processes

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If wireless communication devices use multiple wireless transceivers for different protocols, then the device can communicate with diverse networks, but the device complexity increases

Engineering Contradiction:

Improveprotocol compatibilityVSAvoidtransceiver configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universality by creating a shared association information structure that can be utilized by multiple wireless transceivers with different protocols (e.g., WLAN, Bluetooth, cellular). The first wireless transceiver obtains association information that can be shared with and understood by the second wireless transceiver, enabling multi-protocol communication capability while managing device complexity through a unified information-sharing approach

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A first wireless transceiver communicates pre-association data via a first wireless network, the pre-association data relating to a second wireless network, wherein the first wireless network supports communication via a first wireless protocol and wherein the second wireless network supports communication via a second wireless protocol that is different from the first wireless protocol. A second wireless transceiver communicates the pre-association data with the first wireless transceiver via a transceiver interface and processes the pre-association data to support an association by the second wireless transceiver with the second wireless network.
