C-RNC Local Cell Capability Determination via Default IUB Bearer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for determining the support capability of a local cell in wireless communication networks require analyzing multiple capability information, leading to increased processing time for the controlling radio network controller (C-RNC) and reduced system performance.
Innovation Solution
The method involves the C-RNC receiving capability support information from a node B, defaulting that the local cell supports a separate IUB transport bearer and determining uplink multi-carrier and shared IUB transport bearer capabilities based on this information, thereby reducing the need for extensive analysis and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the C-RNC analyzes multiple capability information (uplink multi-carrier capability, shared IUB transport bearer capability, separate IUB transport bearer capability) to determine local cell support capability, then the determination accuracy is improved, but the processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a capability support information template that includes all necessary capability fields (uplink multi-carrier capability, shared IUB transport bearer capability, separate IUB transport bearer capability) before the C-RNC receives capability information from the node B. This template is prepared in advance according to the capability type (single-carrier or multi-carrier), so when the C-RNC receives the capability information, it only needs to fill in the corresponding fields rather than analyzing multiple different information structures, thereby reducing processing time while maintaining determination accuracy.
2Measurement precision
If the C-RNC receives and processes detailed capability support information from the node B, then the capability determination accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the capability support information into distinct fields corresponding to different capability types (uplink multi-carrier capability, shared IUB transport bearer capability, separate IUB transport bearer capability). The C-RNC processes each field separately based on the capability type, rather than handling a monolithic capability information structure. This segmentation allows the C-RNC to simplify its processing logic by handling each capability aspect independently, reducing overall processing complexity while maintaining comprehensive capability determination.
3Adaptability or versatility
If the system supports both single-carrier and multi-carrier technologies with multiple IUB transport bearer modes, then the adaptability is improved, but the processing time for capability determination increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring capability support information templates for both single-carrier and multi-carrier scenarios before runtime operation. The template includes all necessary capability fields pre-organized according to the capability type, allowing the C-RNC to quickly match the received capability information against the appropriate template without performing complex analysis. This pre-prepared template structure enables the system to maintain adaptability to both carrier technologies while significantly reducing the time required for capability determination.
Solution Approach 2:
The patent applies parameter changes by dynamically selecting which capability fields need to be processed based on the carrier type and capability information received from the node B. The C-RNC adjusts its processing parameters (which fields to analyze, how to interpret the information) according to the specific capability type, allowing efficient handling of both single-carrier and multi-carrier scenarios without unnecessary processing of irrelevant fields, thus reducing overall processing time while maintaining full adaptability.
