Modem Modulation Mode Auto-Adjustment via Indication Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of configuring modulation modes between different generations of modems in communication networks reduces network deployment efficiency, as operators need to manually adjust modulation modes of newer modems to match those of previous generations, leading to inefficient operations.
Innovation Solution
A method and modem design where a first modem generates and sends indication information about its current modulation mode to a second modem through data frames, allowing the second modem to adjust its modulation mode to match, thereby eliminating the need for manual configuration and ensuring compatibility across different generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of modulation modes is used to ensure compatibility between different generation modems, then compatibility is achieved, but operation complexity increases and deployment efficiency decreases
Solution Approach 1:
The modem automatically performs modulation mode matching by generating indication information from its current working modulation mode and sending it to the peer modem through data frames. The peer modem receives this indication information and automatically adjusts its modulation mode to match, eliminating the need for manual operator configuration and achieving self-service compatibility.
Solution Approach 2:
The system performs preliminary action by having the first modem generate and send indication information about its modulation mode before the second modem needs to adjust. This advance notification allows the second modem to proactively configure its modulation mode to match, preventing compatibility issues rather than reacting to them.
2Adaptability or versatility
If manual configuration of modulation modes is used to ensure compatibility between different generation modems, then compatibility is achieved, but deployment time increases
Solution Approach 1:
The automatic modulation mode matching mechanism enables modems to self-configure compatibility settings through exchanged indication information, eliminating the time-consuming manual configuration process and significantly reducing network deployment time while maintaining compatibility.
Solution Approach 2:
The system implements feedback by having the first modem send indication information about its modulation mode to the second modem. The second modem uses this feedback to automatically adjust its modulation mode, creating a closed-loop configuration process that eliminates manual intervention and accelerates deployment.
3Productivity
If automatic modulation mode adjustment is implemented, then deployment efficiency improves, but device complexity increases
Solution Approach 1:
The indication information mechanism serves multiple functions: it conveys modulation mode identification, enables automatic matching, and ensures compatibility across different modem generations. This multi-functionality achieves automatic modulation mode matching without requiring complex dedicated systems, balancing deployment efficiency with device complexity.

AI summary
The present invention provides a method and modem for adjusting a modulation mode. In embodiments of the present invention, a first modem generates indication information according to a current working first modulation mode, so that the first modem can send the indication information to a second modem through a data frame. Therefore, the second modem adjusts a current working second modulation mode of the second modem according to the indication information, so that the adjusted second modulation mode is consistent with the first modulation mode. Therefore, the problem of complex operations in the prior art, caused by that an operator configures a modulation mode of a second modem as a current working modulation mode of a peer modem, that is, a first modem, can be avoided, and efficiency of network deployment can be improved.
