Service Signal Multiplexing via Padding for Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications networks, transmitting multiple service signals with different transmission rates over separate channels results in low efficiency and wastage of transmission resources, as each channel can only carry one type of signal and utilizes bandwidth inefficiently.
Innovation Solution
Inserting padding signals into service signals to create signals with integer multiple transmission rates, allowing for multiplexing into a single channel, thereby improving transmission efficiency and reducing resource occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple service signals are transmitted through separate communications channels, then each signal can be transmitted reliably, but transmission efficiency is low and channel resources are wasted
Solution Approach 1:
The patent merges multiple service signals with the same coding type into a single multiplexed signal for transmission through one communications channel. The first network device performs multiplexing on N service signals to generate a multiplexed signal, which is then transmitted through a single channel to the second network device. This combining approach improves transmission efficiency and reduces channel resource waste while maintaining reliable transmission through proper signal integration and synchronization mechanisms.
Solution Approach 2:
The patent enables a single communications channel to carry multiple service signals simultaneously by implementing a universal multiplexing framework. The communications channel is designed to handle different service signals with the same coding type through standardized multiplexing procedures, allowing the channel to serve multiple functions and transmit multiple signals reliably without requiring dedicated separate channels for each signal.
2Reliability
If each communications channel transmits only one type of service signal, then signal integrity is maintained, but channel resources are greatly wasted when transmission rate is far less than bandwidth
Solution Approach 1:
The patent combines multiple service signals into a single multiplexed signal that fully utilizes the available channel bandwidth. By multiplexing N service signals with the same coding type into one signal stream, the system maximizes channel resource utilization. The bandwidth that would otherwise be wasted when transmitting low-rate signals through dedicated channels is now efficiently used by aggregating multiple signals, thereby reducing channel resource waste while maintaining signal integrity through proper multiplexing and demultiplexing operations.
3Reliability
If multiple communications channels are used to transmit service signals, then transmission reliability is ensured, but transmission resources are occupied and efficiency is reduced
Solution Approach 1:
The patent reduces the number of communications channels required by merging multiple service signals into a single multiplexed signal. Instead of allocating separate channels for each service signal, the system uses one channel to carry the multiplexed signal containing N service signals. This significantly reduces transmission resource occupancy while maintaining reliable transmission through the robust multiplexing framework that ensures proper signal integration, transmission, and reconstruction at the receiving end.

AI summary
This application discloses a service signal transmission method and apparatus, and belongs to the field of communications technologies. The method includes: obtaining, by a first network device, N first service signals, where coding types of the N first service signals are the same, and at least two of the N first service signals have different transmission rates, where N ≥ 2; inserting padding signals into the N first service signals, to obtain N second service signals, where transmission rates of the N second service signals are integer multiples of a reference rate; and multiplexing the N second service signals into one third service signal, and sending the third service signal to a second network device. In this application, the padding signals are inserted into the N first service signals, to obtain the N second service signals whose transmission rates have an obvious integer-ratio characteristic. This resolves a problem of multiplexing service signals with different transmission rates, and implements multiplex transmission of the N first service signals, thereby improving service signal transmission efficiency, and reducing occupied transmission resources.
