Solution Overview

Problem

Current digital home systems face instability and speed limitations due to reliance on a single access mode, either wired or wireless, for connecting to Wide Area Networks, leading to poor user experience and potential network access issues.

Innovation Solution

An access system and method that employs mutual standby for both wired and wireless access modes, allowing seamless switching between CPE and MID sub-systems via a connection interface, ensuring stable network connectivity and bandwidth through a combination of PPPoE and PPP protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single access mode (wired or wireless) is used to connect to WAN, then the device complexity is reduced, but the network reliability deteriorates due to potential access failures

Engineering Contradiction:
Improvenetwork connection stabilityVSAvoidaccess system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The access system is segmented into two independent access units: a wired access unit and a wireless access unit. Each unit can independently connect to the WAN, allowing the system to maintain network connectivity even if one access method fails. This segmentation directly resolves the contradiction by improving reliability through redundancy while keeping each individual access unit relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If both wired and wireless access modes are supported simultaneously, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveaccess mode compatibilityVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The access system is designed with multi-functionality by incorporating both wired and wireless access units that can independently operate. The system can adapt to different network environments (wired or wireless availability) and switch between access modes as needed. This universal design improves adaptability while the modular structure helps manage complexity by keeping each access unit independent and standardized.

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

AI summary

The present invention provides an access method, system and device. In the solution of the present invention, a CPE sub-system receives a connection request for carrying out a data connection with a WAN, when determining that the CPE sub-system itself is not able to carry out a wired connection with the WAN, sends the connection request to an MID sub-system through a connection interface, so that a wireless connection is carried out with the WAN through the MID sub-system; the MID sub-system receives a connection request for carrying out a data connection with a WAN, when determining that the MID sub-system itself is not able to carry out a wireless connection with the WAN, sends the connection request to the CPE sub-system through the connection interface, so that a wired connection is carried out with the WAN through the CPE sub-system. In accordance with the solution of the present invention, not only the wired access but also the wireless access is able to be realized for the WAN, thereby providing stable network connection for home users and bringing great convenience for the users.
