Base Station Radio Link Setup Using Old Board CE Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WCDMA systems, the mixed insertion of new and old baseband boards in a NodeB leads to inconsistencies in E-DCH CE consumption rules, causing false admissions due to accumulative errors in resource management between the NodeB and the RNC.
Innovation Solution
A method is implemented where the base station sends a message to the base station controller including channel element consumption rules of both new and old baseband boards, and instructs the controller to set up a radio link according to the old board's consumption rule when the new board's rule results in insufficient assignable channel elements, ensuring uniformity and accurate resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the NodeB uses the CE consumption rule of the new baseband board for reporting to the RNC, then the processing capability is improved and fewer CEs are consumed, but the consistency between the RNC-maintained CE resources and the actual NodeB resources deteriorates, causing false admissions
Solution Approach 1:
The patent changes the parameter used for reporting from the new board's CE consumption rule to the old board's CE consumption rule. This parameter change ensures that the RNC's resource maintenance is consistent with the actual resource consumption in the NodeB, preventing false admissions while still allowing the system to utilize both new and old baseband boards effectively.
Solution Approach 2:
The patent uses the CE consumption rule of the old baseband board as a reference model for reporting to the RNC. By copying the old board's consumption rule characteristics, the system ensures uniformity in resource management across mixed board configurations, maintaining reliability while supporting productivity improvements from new boards.
2Productivity
If the NodeB selects the CE consumption rule of the new baseband board for reporting, then the resource allocation efficiency is improved, but the measurement precision of actual resource consumption deteriorates due to inconsistency between RNC and NodeB
Solution Approach 1:
The patent changes the reporting parameter from new board CE consumption rule to old board CE consumption rule. This ensures that the RNC's resource status measurements accurately reflect the actual consumption in the NodeB, improving measurement precision while maintaining efficient resource allocation through proper rule selection.
3Adaptability or versatility
If the RNC maintains CE resources according to the new baseband board's consumption rule, then the system supports higher processing capability, but the uniformity of CE resources between RNC and NodeB sides deteriorates, causing accumulative errors
Solution Approach 1:
The patent changes the maintenance parameter from new board CE consumption rule to old board CE consumption rule. This parameter change ensures uniformity of CE resources between RNC and NodeB sides, preventing accumulative errors while still supporting the system's adaptability to new baseband boards through proper resource management.

AI summary
A method, a base station, and a base station controller for setting up a radio link is provided. The method includes: sending a message to a base station controller, where the message includes channel element consumption rules of a new board and an old board in a base station (101); and instructing the base station controller to set up a radio link according to the channel element consumption rule of the old board when determining that the actual number of assignable channel elements of the old board does not satisfy a radio link setup request sent according to the channel element consumption rule of the new board by the base station controller (102). The present invention can effectively ensure the uniformity of the channel elements maintained by the base station and the base station controller when both of new and old baseband boards exist in the base station.
