Solution Overview

Problem

Conventional direct-mode communication systems require additional connection modules and protocols to establish connections between client direct-mode communication apparatuses, leading to complex hardware design and limited flexibility.

Innovation Solution

A method where client direct-mode communication apparatuses register with a backhaul network, determining location relationships and transmitting Wi-Fi connection information to establish direct Wi-Fi connections using existing hardware modules and adjusted communication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional connection modules and communication protocols are used to establish connections between client direct-mode communication apparatuses, then communication connection can be created, but hardware design becomes more complex and existing hardware cannot support this

Engineering Contradiction:

Improvecommunication connectionVSAvoidhardware design

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The backhaul network serves as an intermediary that facilitates direct Wi-Fi connections between client apparatuses. Instead of requiring complex additional connection modules in each client device, the backhaul network provides connection information (SSIDs, passwords, channel data) that enables clients to establish direct connections using their existing Wi-Fi hardware capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses existing Wi-Fi communication protocols and hardware capabilities that are already present in client devices. Rather than creating new proprietary connection protocols, the invention leverages standard Wi-Fi protocols that clients can execute with their existing hardware, thus avoiding the need for additional connection modules.

Inventive Principle:

Principle #26Copying

2Reliability

If conventional direct-mode communication system uses additional connection modules and protocols, then communication connection can be established, but system flexibility is limited

Engineering Contradiction:

Improvecommunication connectionVSAvoidsystem flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The backhaul network provides a universal service by managing connection establishment for multiple client apparatuses simultaneously. It stores and manages Wi-Fi connection information for various clients and can facilitate connections between any pair of clients that meet location criteria, making the system highly adaptable and versatile without requiring device-specific customization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts connection parameters such as Wi-Fi channels, SSIDs, and passwords based on location relationships and network conditions. The backhaul network can modify these parameters to optimize direct connections between clients, enhancing system flexibility and adaptability to different scenarios.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If backhaul network determines location relationship and transmits Wi-Fi connection information, then direct Wi-Fi connection can be established using existing hardware, but requires coordination through backhaul network

Engineering Contradiction:

Improvehardware designVSAvoidconnection establishment time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The backhaul network pre-determines location relationships between client apparatuses and prepares Wi-Fi connection information in advance. By performing these determinations beforehand and storing connection data ready for transmission, the system minimizes the time required when actual direct connections need to be established, offsetting the coordination overhead with preparatory work.

AI summary

A direct-mode communication system comprises a first client direct-mode communication apparatus and a backhaul network. The first client direct-mode communication apparatus transmits a register signal to the backhaul network to register with the backhaul network. After the first client direct-mode communication apparatus is registered, the backhaul network determines a location relationship between the first client direct-mode communication apparatus and a second client direct-mode communication apparatus. The backhaul network transmits a piece of wi-fi connection information to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus creates a wi-fi direct-mode communication connection with the second client direct-mode communication apparatus according to the piece of wi-fi connection information.
