Modem Control Information Management via Server-Side Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modems in wireless communication systems face performance issues due to time delays and unreliable measurement information, especially in dense cell areas and poor communication environments, leading to prolonged operation times and frequent errors.
Innovation Solution
A method and apparatus that store and manage modem operation-related information, such as cell information, signal strength, and interference data, in a database, allowing for the transmission of updated modem control information to enhance performance by reducing repetitive operations and improving measurement reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional modems perform repetitive measurements and operations to obtain control information, then the modem can operate autonomously without external assistance, but time delays occur and measurement reliability decreases
Solution Approach 1:
The patent applies preliminary action by having a server perform measurements and generate modem control information in advance based on stored location information and historical data. The server calculates control information including cell identity, signal strength, frequency offset, and timing offset before the modem needs them, thereby eliminating time delays and improving measurement reliability without requiring repetitive operations by the modem itself.
2Adaptability or versatility
If the modem performs continuous cell search and signal quality measurements, then the modem maintains up-to-date information, but the operation time is prolonged and errors increase
Solution Approach 1:
The patent introduces a server as an intermediary that performs measurements and generates control information on behalf of the modem. The server uses stored location information and historical measurement data to calculate control information including channel state information and interference information, thereby maintaining communication performance without requiring the modem to perform continuous measurements that prolong operation time and increase errors.
3Productivity
If the modem uses stored location information to obtain control information from a server, then access time to base station is reduced, but additional communication overhead is introduced
Solution Approach 1:
The patent applies universality by designing a server that serves multiple functions: storing location information, performing measurements, generating control information, and communicating with multiple modems. This multi-functional approach reduces access time for individual modems while managing system complexity through centralized processing rather than distributing complexity across multiple devices.
