The values on the LLC tab report the processing measurements for the Logical Link Control layer in a UMTS Gb interface test.
In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...
Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...
Elapsed Time is the first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.
Test Iteration reports the current iteration in a repeating test session. It is only displayed when a Number of Iterations is defined for the test session.
The following measurements record the number and types of Information/Supervisory, Unnumbered, and Unconfirmed Information commands and responses exchanged between the MNs and the SGSN.
IS Frame RR Received Count — The number of Receive Ready commands and responses received. The RR command indicates that the peer is ready to receive an Information frame and an acknowledgement may be requested. The RR response acknowledges previously received Information frames.
IS Frame RR Transmitted Count — The number of Receive Ready commands and responses sent to the SGSN.
IS Frame Ack Received Count — The number of Acknowledgements received in acknowledgement of sequential Information frames.
IS Frame Ack Transmitted Count — The number of Acknowledgements sent to the SGSN.
IS Frame RNR Received Count — The number of Receive Not Ready commands and responses received, indicating that the peer is temporarily unable to receive incoming frames.
IS Frame RNR Transmitted Count — The number of Receive Not Ready commands and responses sent to the SGSN.
IS Frame SACK Received Count — The number of Selective Acknowledgements received, acknowledging receipt of the specified frames.
IS Frame SACK Transmitted Count — The number of Selective Acknowledgements sent to the SGSN.
Unnumbered Frame DM Received Count — The number of Disconnected Mode responses received, indicating that the SGSN is in a state that prevents ABM mode.
Unnumbered Frame DM Transmitted Count — The number of Disconnected Mode responses sent to the SGSN.
Unnumbered Frame DISC Received Count — The number of Disconnect commands received, directing the MN to terminate ABM mode.
Unnumbered Frame DISC Transmitted Count — The number of Disconnect commands sent to the SGSN.
Unnumbered Frame UA Received Count — The number of Unnumbered Acknowledgement responses received, indicating that the SGSN received and accepted an SABM or a DISC command.
Unnumbered Frame UA Transmitted Count — The number of Unnumbered Acknowledgement responses sent to the SGSN.
Unnumbered Frame SABM Received Count — The number of Set Asynchronous Balanced Mode commands received, directing the MN to switch to ABM acknowledged mode.
Unnumbered Frame SABM Transmitted Count — The number of Set Asynchronous Balanced Mode commands sent to the SGSN.
Unnumbered Frame FRMR Received Count — The number of Frame Reject responses received, indicating that the SGSN received a frame that contained an undefined or unsupported field, an incorrect length, or an invalid length.
Unnumbered Frame FRMR Transmitted Count — The number of Frame Reject responses sent to the SGSN.
Unnumbered Frame XID Received Count — The number of Exchange Identification commands and responses received during negotiation of SAP parameters.
Unnumbered Frame XID Transmitted Count — The number of Exchange Identification commands and responses sent to the SGSN.
Unnumbered Frame NULL Received Count— The number of NULL commands received.
Unnumbered Frame NULL Transmitted Count — The number of NULL commands sent to the SGSN, indicating a cell update.
UI Frame Received Count — The number of Unconfirmed Information commands received.
UI Frame Transmitted Count — The number of Unconfirmed Information commands sent.
IS Frame Re-transmission Count — The number of Information/Supervisory frames that were re-transmitted due to a timeout.
IS Frame Duplicate Received Count — The number of duplicate Information/Supervisory frames received.
T200 Timer Expired Count — The number of times a SAP's T200 timer expired.
