Solution Overview
Problem
In telecommunications systems, digital physical layer data lacks identifying characteristics, making it difficult to discriminate between different frequency channels and antennas, which hinders independent characterization and efficient communication.
Innovation Solution
An interceptor system with an interface device and processing unit that retrieves data from communication links between radio frequency and baseband processing units, determining the interface link protocol by analyzing the organization of the data, allowing for characterization and management of digital data.

Engineering Contradiction Analysis
1Loss of information
If digital physical layer data is communicated between distributed physical layer entities, then communication functionality is achieved, but the data lacks identifying characteristics making it difficult to discriminate among different frequency channels and antennas
Solution Approach 1:
The patent applies preliminary action by inserting identifying characteristics (such as channel identifiers, antenna identifiers, frame markers, and slot markers) into the digital data stream before the data is communicated between distributed physical layer entities. This preprocessing ensures that the data carries necessary identification information from the outset, eliminating the need for complex post-processing characterization and enabling easy discrimination among different frequency channels and antennas.
2Measurement precision
If identifying characteristics are added to digital data, then data discrimination capability is improved, but system complexity increases
Solution Approach 1:
The patent merges the identification function with the existing data transmission framework by integrating identifying characteristics directly into the data stream structure. Rather than adding separate identification systems, the patent combines channel identifiers, antenna identifiers, and timing markers with the physical layer data, allowing discrimination functionality to be achieved within the existing communication infrastructure without significant system complexity increases.
Solution Approach 2:
The patent creates a universal data structure that serves multiple functions simultaneously: the same identifying characteristics enable discrimination among frequency channels, antennas, and time slots while also supporting data transmission and synchronization. This multi-functional approach allows a single system to handle various discrimination requirements without proportionally increasing complexity.

AI summary
Certain aspects are directed to an interceptor system for characterizing digital data communicated between certain points in a telecommunication system. The interceptor system includes an interface device and a processing device. The interface device can retrieve data from at least one communication link between a radio frequency processing unit and a baseband processing unit of a telecommunication system. The data includes digital data communicated between the radio frequency processing unit and the baseband processing unit. The processing device can determine an interface link protocol for communicating with terminal equipment via the telecommunication system. The interface link protocol can be determined based on an organization of the data retrieved from the communication link.
