Base Station Automatic Channel Setup via BOOTP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing and maintaining channels between base stations and base station controllers in 3G systems lack an automatic mechanism, leading to complex operations, high maintenance costs, and poor maintenance quality due to the need for manual configuration and fixed communication ports or IP addresses.
Innovation Solution
A method is introduced to automatically establish an IP-over-ATM channel between base stations and base station controllers using the Bootstrap Protocol (BOOTP) to allocate IP addresses and establish default Permanent Virtual Connections (PVCs), enabling base stations to connect to the operating and maintaining system, thereby simplifying network maintenance and reducing costs.

Engineering Contradiction Analysis
1Ease of operation
If manual configuration methods are used to establish maintaining channels, then the channel can be established, but the operation complexity and maintenance cost increase significantly
Solution Approach 1:
The base station automatically establishes maintaining channels by sending BOOTP requests through default PVCs to obtain IP addresses and configure IPOA channels without manual intervention. The system performs self-configuration and self-establishment of communication channels, eliminating the need for servicing staff to manually configure data at BS side and BSC side.
Solution Approach 2:
Default PVCs and IP addresses are pre-configured at the factory before the base station is deployed. When the base station starts, it uses these pre-established default PVCs and preset IP addresses to contact the operating and maintaining station, avoiding the need for real-time manual configuration during deployment.
2Ease of manufacture
If fixed communication ports or IP addresses are used for all base stations, then the configuration is simplified, but the network maintenance and management becomes complex during startup
Solution Approach 1:
Instead of using fixed IP addresses for all base stations, the system dynamically assigns IP addresses through BOOTP protocols during the base station startup process. Each base station receives a unique IP address from the BSC/RNC via BOOTP Reply, allowing flexible and adaptive configuration without manual intervention.
Solution Approach 2:
The base station sends BOOTP requests to the BSC/RNC, receives BOOTP replies containing assigned IP addresses, and uses this feedback information to establish the IPOA channels. This feedback mechanism ensures that each base station obtains the correct IP address and configuration information automatically during startup.
3Productivity
If all base stations start simultaneously using default PVCs, then the launching speed increases, but the network maintenance and management becomes very complex
Solution Approach 1:
The system segments the channel establishment process into two independent parts: default PVC establishment (which can be done simultaneously for all base stations) and IPOA channel establishment (which occurs after IP address assignment). This segmentation allows base stations to start simultaneously while maintaining manageable complexity through automated IP address assignment and channel configuration.

AI summary
A method automatically establishes a base station operating and maintaining channel in International Mobile Telecommunications 2000. A BS initiates a BOOTP Request to the base station controller (BSC) or RNC through the IPOA channel between the BS and the BSC/RNC, and then the BS obtains the IP address allocated to it from the reply from the BSC/RNC, so that an operating and maintaining channel is established between the BS and the BSC/RNC. A BS can establish a maintaining channel for itself automatically when starting, avoiding IP address confliction and parallel starting problems. Moreover, establishing a maintaining channel for the BS results in an easy and small workload. Thus programs and data can be loaded automatically to the BS, and the BS can be effectively configured and maintained by a remote device (i.e., the operating and maintaining station of the BS) at a low cost, and good quality is realized. The method is suitable for star networking, recurrent networking, tree networking, ring networking, etc.
