Methods, test systems and arrangements for verifying compliance with requirement specifications

A computer program product comprising a non-transitory computer readable medium, having thereon a computer program comprising program instructions, the computer program being loadable into a data-processing unit of a test system connectable to a communication device for verifying compliance of the communication device with one or more requirement specifications, the computer program, when run by the data-processing unit, configured to cause the test system to:

• establish a link between the test system and the communication device;
• close a test loop comprising the test system and the communication device by activating a test loop function of the communication device, wherein activating the test loop function comprises sending an indicator from the test system to the communication device that defines a specific event;
• send data in a downlink of the test loop from the test system to the communication device;
• disconnect the link after sending the data in the downlink but before the specific event has occurred, the specific event controlling when the communication device transfers at least some of the data to an uplink transmission arrangement of the communication device;
• verify that a link re-establishment procedure is executed correctly by the communication device;
• and
• verify transmission in an uplink of the test loop from the communication device to the test system.

A test system connectable to a communication device and for verifying compliance of the communication device with one or more requirement specifications, the test system comprising a transmitter, a receiver, and processing circuitry, the processing circuitry configured to:

• establish, via the transmitter, a link between the test system and the communication device;
• and
• close, via the transmitter and the receiver, a test loop comprising the test system and the communication device by activating a test loop function of the communication device, wherein activating the test loop function comprises sending, via the transmitter, an indicator from the test system to the communication device that defines a specific event;
• send data, via the transmitter, in a downlink of the test loop from the test system to the communication device;
• disconnect the link after the transmitter has sent the data in the downlink but before the specific event has occurred, the specific event controlling when the communication device transfers at least some of the data to an uplink transmission arrangement of the communication device;
• verify that a link re-establishment procedure is executed correctly by the communication device;
• and
• verify transmission in an uplink of the test loop from the communication device to the test system.

An arrangement for verifying requirement specifications comprising at least a communication device and a test system, the test system configured to verify compliance of the communication device with the requirement specifications and comprising a transmitter, a receiver, and processing circuitry, the processing circuitry configured to:

• establish a link between the test system and the communication device;
• close a test loop comprising the test system and the communication device by activating a test loop function of the communication device, wherein activating the test loop function comprises sending an indicator from the test system to the communication device that defines a specific event;
• send data in a downlink of the test loop from the test system to the communication device;
• disconnect the link after sending the data in the downlink but before the specific event has occurred, the specific event controlling when the communication device transfers at least some of the data to an uplink transmission arrangement of the communication device;
• verify that a link re-establishment procedure is executed correctly by the communication device;
• and
• verify transmission in an uplink of the test loop from the communication device to the test system.
