IPOA Channel-Based O&M for Base Station Auto-Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing operation and maintenance channels in WCDMA cellular mobile communication systems are labor-intensive, error-prone, and difficult to automate, especially in remote areas, leading to increased maintenance costs and degraded quality due to the lack of automatic far-end auto-configuration mechanisms.
Innovation Solution
A method is introduced to establish IPOA-based default operation and maintenance channels by creating a default PVC between a base station and a base station controller, initiating a BOOTP request, and assigning an IP address, allowing for automatic establishment of operation and maintenance channels, enabling parallel launching and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of O&M data at base stations is used, then base station startup can be achieved, but the operation becomes extremely difficult and labor-intensive when base stations are located far from the base station controller or in remote areas
Solution Approach 1:
The base station automatically configures its own O&M data by initiating a BOOTP request to obtain an IP address and automatically establishing an IPOA channel, eliminating the need for manual configuration even in remote locations
Solution Approach 2:
A default PVC is pre-configured between the base station and base station controller, enabling automatic channel establishment before actual operation begins, so that no manual setup is needed during deployment
2Reliability
If fixed IP addresses are assigned to all base stations, then the operation and maintenance center can manage base stations, but all base stations cannot be launched simultaneously and IP address conflicts occur
Solution Approach 1:
The system dynamically assigns IP addresses to base stations through BOOTP requests rather than using fixed pre-configured addresses, allowing multiple base stations to be deployed simultaneously without IP address conflicts
Solution Approach 2:
The operation and maintenance center responds to BOOTP requests from base stations with assigned IP addresses, providing dynamic feedback that enables automatic configuration and simultaneous deployment of multiple base stations
3Extent of automation
If automatic establishment of O&M channels is implemented, then labor costs and errors are reduced, but complex protocols and mechanisms are required
Solution Approach 1:
The patent uses standard, widely-supported protocols (BOOTP and IPOA) that are already embedded in most networking equipment, avoiding the need for custom complex protocols while achieving automatic O&M channel establishment
Solution Approach 2:
The base station controller acts as an intermediary that forwards BOOTP requests between remote base stations and the operation and maintenance center, enabling automatic channel establishment without requiring direct complex communication between all components

AI summary
This invention discloses a method for establishing IPOA channel-based maintenance channels. The invention establishes an IPOA channel between a base station and a base station controller with configuration of the base station. A BOOTP request is initiated from the base station to an operation and maintenance center, and the base station obtains an IP address assigned to it from a response sent from the operation and maintenance center, so that an operation and maintenance channel is established between the base station and the base station controller. The invention can solve automatic base station launching problem, and can prevent IP address conflicts and implement parallel launching of base stations. In addition, with the method described in this invention, operation of establishing maintenance channels is simple, light in workload, and reliable. Thus, program and data auto-loading as well as configuration and maintenance of base station(s) at far end (i.e., the operation and maintenance center) can be achieved. The method described in this invention is superior in quality and low cost in maintenance, and can be applied to various networking patterns, such as star-type, chain-type, and tree-type networks.
