Solution Overview

Problem

In existing IPRAN networks, static routes from a UPE to a base station require manual configuration based on pre-acquired IP address planning, leading to human errors and communication failures due to inaccurate planning information.

Innovation Solution

A method where a UPE automatically delivers a static route by reading and processing DHCP relay agent packets, utilizing the interface and service addresses allocated to the base station, thereby eliminating the need for manual configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration of static routes is performed based on pre-acquired IP address planning, then the static route can be established, but human errors and communication failures occur due to inaccurate planning information

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidconfiguration complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The UPE automatically obtains IP address planning information by acting as a DHCP relay agent and reading DHCP packets. The system self-configures static routes without human intervention, eliminating manual configuration errors while maintaining communication reliability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The DHCP protocol serves as an intermediary that automatically conveys IP address planning information from the server to the UPE. This mediator eliminates the need for manual information transfer between wireless and data communication departments, reducing human errors

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual configuration of static routes is performed, then routing can be established, but manpower costs are consumed and configuration time is increased

Engineering Contradiction:
Improvedeployment efficiencyVSAvoidconfiguration time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

IP address planning information is pre-configured on the DHCP server before site deployment. When the base station boots, the UPE automatically retrieves this pre-prepared information through DHCP packets, eliminating the need for manual pre-acquisition and configuration activities

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The UPE automatically reads DHCP packets containing IP address planning information and self-configures static routes without human intervention. This automation dramatically reduces both manpower costs and configuration time, improving deployment efficiency

Inventive Principle:
Principle #25Self-service

AI summary

The present invention is applicable to and relates to the field of communications technologies, and provides a method for delivering a static route and a UPE. The method includes: reading, by a UPE, a packet; and delivering a corresponding static route according to related information carried in the packet. The present invention avoids problems that when a site is deployed on a large-scale radio access network, a base station cannot operate normally and a data communications device repeatedly performs troubleshooting and debugging on site caused by differences between preliminary data planning and actual site deployment data. A static route is automatically delivered by processing a packet, thereby reducing manpower costs and avoiding occurrence of human errors.
