The values on the GMM tab report the control plane processing measurements for the GMM layer in a UMTS test case and HNB test case.
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.

Average Periodic RAU Time — The average time required to perform a periodic Routing Area Update, measured from the time the RAU Request is sent until the RAU Accept message is received.
Average Mobility RAU Time — The average time required to perform a periodic Routing Area Update associated with a mobility event, measured from the time the RAU Request is sent until either an RAU Accept message is received (no P-TMSI received, no active PDP context), an RAU Complete message is sent (received P-TMSI, no active PDP context), or a Service Request is sent (active PDP context).
The following measurements record the messages exchanged between the MN and the SGSN for the service request procedure.
Service Requests — The number of Service Request messages sent to the SGSN, initiating a service request procedure.
Service Accepts — The number of Service Accept messages received from the SGSN, indicating that the request was accepted and processed. Service Accepts are not sent if the Service Request was in response to a Paging message.
Service Rejects — The number of Service Reject messages received from the SGSN, indicating that the request was rejected due to one of the errors listed below.
The following measurements record errors, by cause value, encountered during attach, service request, routing area update, and detach procedures.
Attach Timeouts — The number of times an Attach Request was sent without receiving a response from the SGSN.
Authentication Failures — The number of times an Authentication and Ciphering Reject message was received from the SGSN, indicating that the MN's IMSI or IMEI failed GMM authentication with the network during an attach.
Detach Timeouts — The number of times a Detach Request was sent without receiving a response from the SGSN.
Service Request Timeouts — The number of times a Service Request was sent without receiving a response from the SGSN.
RAU Timeout Count — The number of times a Routing Area Update Request was sent without receiving a response from the SGSN.
IMSI Unknown In HLR (2) — The MN's IMSI is not registered in the HLR.
Illegal MSs (3) — The MN's identity is not acceptable or the MN failed authentication.
Illegal MEs (6) — The MN's ME is banned from the network.

GPRS and NonGPRS Service Not Allowed (8) — The MN is not allowed to operate GPRS or non-GPRS services.
MS Identity Not Derived by NE (9) — The network cannot derive the MN's identity from the P-TMSI.
Implicit Detach (10) — The network has implicitly detached the MN due to the expiration of the mobile reachable timer or due to an SGSN restart.
PLMN Not Allowed (11) — The MN requested a location update from a PLMN in which it is not allowed to operate.
Location Area Not Allowed (12) — The MN requested a location update from a location area in which it is not allowed to operate.
Roaming Not Allowed in Location Area (13) — The MN requested a location update from a location area in a PLMN that offers roaming service only by subscription.
GPRS Services Not Allowed in PLMN (14) — The MN requested service in a PLMN that does not offer roaming service to that MN.
No Suitable Cells in Location Area (15) — The MN requests a location update from a location area in which it is not allowed to operate and should find another, allowed location area in the PLMN.
