Fixed Access Device Mobile Core Network Integration

Solution Overview

Problem

Conventional fixed access technologies face challenges in deploying fiber to the home, leading to long deployment periods and high costs, especially when migrating from wireless to fixed broadband services, as they require new end-to-end network deployments and maintenance.

Innovation Solution

A method for accessing a mobile core network using a fixed access device, which allows for the provision of broadband services without establishing a new fixed core network, enabling quick service migration and network simplification by leveraging existing deployed mobile core networks for both fixed and wireless access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fiber to the home is deployed using conventional fixed access, then broadband service quality is improved, but deployment period and costs increase

Engineering Contradiction:

Improvebroadband service qualityVSAvoiddeployment period

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges fixed access and mobile core network functions into a unified system. The fixed access device connects to the mobile core network, allowing FTTx users to access services through the existing mobile network infrastructure rather than requiring a separate fixed core network deployment. This combination enables high-quality broadband service while utilizing already-deployed mobile network resources.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mobile core network is designed to serve dual purposes: it provides both mobile wireless access services and fixed broadband access services through the fixed access device. This multi-functionality allows the same network infrastructure to support multiple service types, eliminating the need for separate fixed core network deployment and reducing both time and cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the fixed core network function from the traditional fixed access architecture and replaces it with mobile core network functions. The fixed access device acts as an interface that translates fixed access protocols to mobile network protocols, allowing FTTx users to be served by the mobile core network without requiring a separate fixed core network infrastructure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mobile core network is designed to serve dual purposes: it provides both mobile wireless access services and fixed broadband access services through the fixed access device. This multi-functionality allows the same network infrastructure to support multiple service types, eliminating the need for separate fixed core network deployment and reducing both time and cost.

AI summary

Embodiments of this application provide example methods for accessing a core network by using a fixed access device. One example method includes: receiving, a network registration request sent by customer-premises equipment; sending a network registration request message for the CPE to a mobile core network based on the network registration request; receiving an authentication request message; performing physical location authentication for the CPE based on a physical location identifier; in response to determining that the physical location authentication succeeds, sending an authentication response to the mobile core network; receiving a registration success message sent by the mobile core network; notifying, based on the registration success message, the CPE that network registration succeeds; and sending a service parameter to the CPE.
