Solution Overview

Problem

Current network access methods are inefficient due to complex operations requiring direct user input, leading to low human-computer interactivity and decreased network access efficiency.

Innovation Solution

A method and apparatus that acquire and multicast access information, including a service set identifier (SSID) and access password, using UDP multicast messages to facilitate network access, allowing for convenient access by storing and transmitting access information through designated multicast addresses, thereby simplifying the process and increasing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional network access method requiring direct user input is used, then security is maintained, but network access efficiency deteriorates due to complex operations

Engineering Contradiction:
Improvenetwork access efficiencyVSAvoidoperation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces a first terminal as an intermediary device that stores access information and transmits it to the second terminal via UDP multicast. This mediator eliminates the need for direct user input on the second terminal, simplifying operations while maintaining secure access through the intermediary's pre-stored credentials

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The first terminal performs preliminary actions by pre-storing access information (SSID and password) and proactively transmitting it to the second terminal before the actual network access is needed. This preliminary preparation eliminates the need for real-time user input, improving access efficiency

Inventive Principle:
Principle #10Preliminary action

2Reliability

If access information is transmitted through multiple channels, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveaccess information transmission reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent utilizes UDP multicast, a universal network communication mechanism, to transmit access information. This single multi-functional approach simultaneously achieves reliable information distribution to multiple terminals and maintains system simplicity, avoiding the need for complex custom transmission protocols

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for accessing network includes: acquiring (101) access information instructing a second terminal to access the network, the access information including a service set identifier SSID and an access password; selecting (102) a plurality of destination addresses including the access information from a designated multicast address segment; and multicasting (103) a plurality of user datagram protocol UDP multicast messages to the second terminal in accordance with the plurality of destination addresses. In the present disclosure, the first terminal stores the access information instructing the second terminal to access the network into a plurality of multicast addresses including the access information, and transmits it to the second terminal by multicasting. A convenient access to the network by the second terminal is realized, thereby avoiding the defect of low human-computer interactivity due to complex operations, thus increasing network access efficiency.
