S102 Session Measurements


The values on the S102 Session tab defines a set of messages between the MME and 1xCS IWS to provide SR VCC and CSFB in MME Nodal and MME Node test cases.

Measurement Values

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.

Session Count

A21-1x Air Interface Signalling message

Sent from an MME or 1xCS IWS to transport 1x air interface message to the peer 1xCS IWS or MME.

This message is used by the MME or 1xCS IWS during Registration, paging, handover (SRVCC) procedures, and mobile originated and mobile terminated SMS procedures.

When the MME receives a 1x air interface message from the UE that is to be sent to 1xCS IWS, the MME encapsulates the 1x air interface message in a A21-1x air interface signalling message and sends it to the 1xCS IWS via the S102 interface. To support CS fallback to 1xRTT registration procedures, it contains the CDMA 2000 sector ID.

When sent from the 1xCS IWS to the MME, the 1xCS IWS encapsulates the 1x handoff direction message or 1xRTT CS paging request (after successful registration for CS fallback to 1xRTT) into A21-1x air interface signalling message.

A21 1x Air Interface Signalling Sent

Indicates the total number of A21 1x Air Interface Signalling Sent messages sent.

A21 1x Air Interface Signalling Received

Indicates the total number of A21 1x Air Interface Signalling Received messages sent.

A21 1x Air Interface Signalling Retries

Indicates the number of times A21 1x Air Interface Signalling Retries message was sent.

NOTE: Depends on the Retires defined on S102 tab.

 

A21 1x Air Interface Signalling Retry Exceeded

Indicates the maximum number of consecutive A21 1x Air Interface Signalling Retries messages which did not receive a response.

A21 Ack Sent

Indicates the message sent from an MME or 1xCS IWS to acknowledge receipt of some A21 message to the peer 1xCS IWS or MME.

A21 Ack Received

Indicates the message received from the peer 1xCS IWS or MME by an MME or 1xCS IWS.
