Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile communication systems using CDMA method face challenges in minimizing transmission delay due to complex protocols and handover processing, which complicates the selection and combination of transport blocks at the radio control base station, leading to increased processing delays.
Innovation Solution
A method where the radio control base station numerically expresses parameters for each transport block, calculates an evaluation parameter indicating communication quality by adding weighted values of payload CRC, CRCI, and bit error rate, and selects the optimum transport block for combination, simplifying the selection process and reducing delays.

Engineering Contradiction Analysis
1Measurement precision
If the radio control base station performs multi-stage comparison and branching processing to select and combine transport blocks, then the selection accuracy is improved, but the transmission delay increases
Solution Approach 1:
The patent combines multiple parameters (payload CRC result, CRCI result, bit error rate) into a single composite evaluation parameter through numerical expression and addition. This merging of multiple evaluation criteria into one unified metric allows the system to maintain accurate transport block selection while eliminating multi-stage comparison processing, thus resolving the contradiction between selection accuracy and transmission delay.
2Reliability
If the radio control base station stores received user data and parameters in memory for later processing, then the processing completeness is improved, but the transmission delay increases
Solution Approach 1:
The patent performs preliminary numerical expression of parameters (payload CRC, CRCI, bit error rate) and calculates the composite evaluation parameter during the initial data reception phase, rather than storing raw data for later processing. This preliminary action ensures processing completeness while eliminating the need for subsequent memory access and processing steps, thereby reducing transmission delay.
3Reliability
If the mobile communication system uses complex protocols for handover processing, then the service quality is improved, but the processing capability requirement increases
Solution Approach 1:
The patent transforms multiple discrete protocol parameters (payload CRC result, CRCI result, bit error rate) into a single composite evaluation parameter through numerical expression and mathematical operations. This parameter transformation simplifies the handover processing logic while maintaining service quality, reducing the processing capability requirements at both mobile terminal and base station sides.
