Method, apparatus and computer program product for monitoring data transmission connections

An analyzer for monitoring data transmission connections between a cellular radio network and a subscriber terminal, the analyzer comprising:

• a monitoring unit configured to monitor a data transmission connection of the subscriber terminal to a cell;
• and
• a processing unit configured to:
• generate, on the basis of the connection information, connection configuration records that contain information on detected and predetermined data transmission configurations, the connection configuration records containing at least one of the following:
• transport formats, logical channel identifiers, mapped radio bearers, and Radio Link Control (RLC) modes;
• and
• identify the protocol configuration automatically by comparing the connection information with the connection configuration records on the basis of a predetermined logic.

An analyzer for monitoring data transmission connections between a cellular radio network and a subscriber terminal, the analyzer comprising:

• monitoring means for monitoring a data transmission connection of the subscriber terminal to a cell;
• first processing means for generating, on the basis of the connection information, connection configuration records that contain information on detected and predetermined data transmission configurations, the connection configuration records containing at least one of the following:
• transport formats, logical channel identifiers, mapped radio bearers, and Radio Link Control (RLC) modes;
• and
• second processing means for identifying the protocol configuration automatically by comparing the connection information with the connection configuration records on the basis of a predetermined logic.

A non-transitory computer-readable recording medium having a computer program recorded thereon that causes a computer to monitor data transmission connections between a cellular radio network and a subscriber terminal, the program causing the computer to execute operations comprising:

• collecting, by means of an analyzer, connection information on a data transmission connection of the subscriber terminal to a cell;
• generating, on the basis of the connection information, connection configuration records that contain information on detected and predetermined data transmission configurations, the connection configuration records containing at least one of the following:
• transport formats, logical channel identifiers, mapped radio bearers, and Radio Link Control (RLC) modes;
• and
• identifying a protocol configuration automatically by comparing the connection information with the connection configuration records on the basis of a predetermined logic.
