100.4 CDMA Events

Call events also encompass VoIP calls. For convenience, this is covered in the present section rather than in section "Data Service Testing Events", ""Data Service Testing Events"".
The designation "MR" below refers to device mode reports.

Call events (Blocked Call; Call*; Dropped Call): Some of these events are also generated for VoIP.

Most of these events have pieces of extra information namely "Call Domain", which is either "Circuit Switched" or "Packet Switched", and "Serving Radio Technology" which holds the radio technology responsible for generating the event. These are not repeated for the individual events below.

Blocked Call


(red)

Triggered by one of the following:

Unexpected change to idle or init state before "Call Established"

CM Call Event (MR) message with "Block or Drop" event received

Generalized Searcher General Status (MR) message received with Searcher State = "Acquisition" or "Sync" and no data session in progress

CM State Response (MR) message with CM System Mode "No Service" event received.

Call Attempt


(gray)

MO call: Origination (ACH) message sent with a voice Service Option.

MT call: Page Response (ACH) message received with a voice Service Option.

Extra information:

Initial RRC State

Call Attempt Retry


(gray)

A call attempt (see "Call Attempt") was repeated.

Extra information:

Initial RRC State

Call End

Triggered by Order (RTCH) or Order (FTCH) message with order code "Release", or CM Call Event (MR) message with "Call End" event received.

Call Established


(green)

MO call: Triggered by Service Connect Completion (RTCH) message, and thus generated immediately after "Call Setup".

MT call: Order (RTCH) message with order code "Connect".

Call Failure MO

A mobile-originated call was either blocked or dropped.

 

Call Failure MT

A mobile-terminated call was either blocked or dropped.

 

Call Initiation

Triggered by Protocol Report containing dialed number.

 

Call Setup

Triggered by Service Connect Completion (RTCH) message.

Extra information:

Call direction (MO/MT)

Call setup time (measured from "Call Attempt", i.e. the first call attempt)

User setup time (measured from "Call Initiation", thus more accurately reflecting the user-perceived setup time; obtained only for MO calls in scripts)

CSFB events: Some of these events have a piece of extra information "Call Domain", which however always takes the value "Circuit Switched".

CSFB Blocked Call


(red)

A CS fallback call was blocked. This can happen in several ways:

The Extended Service Request timed out without any response from network, or the network responded with Service Reject. In this case the CS fallback procedure never reaches the RAT change stage.

RAT change to EV-DO or 1x failed, as indicated by the event "EUTRAN RRC Connection Release Redirected Failure".

After successful RAT change to EV-DO or 1x, the CS call setup failed (CS "Blocked Call" event generated).

Extra information:

Serving Radio Technology

CSFB Call Attempt


(gray)

A CS fallback call attempt was made. Triggered by the Layer 3 message NAS Extended Service Request.

Extra information:

Serving Radio Technology

Initial RRC State

CSFB Call Established


(green)

Same triggers as for "CSFB Call Setup", and generated immediately after that event.

CSFB Call Setup

Triggered by one of the following:

Fast Forward Power Control (MR)

Fast Forward Power Control Statistics (MR)

Reverse Power Control Statistics (MR) message with Service Option (1), (3), (17), (38) or (68), each of which specifies a type of voice service.

Status Snapshot Response (MR) with CDMA Mode = "Init", "Idle", or "Access" after a previous Service Option triggered event was dismissed (aborted).

Extra information:

Call direction (MO/MT)

Call setup time (measured from "CSFB Call Attempt", i.e. the first call attempt)

User setup time (measured from "Call Initiation", thus more accurately reflecting the user-perceived setup time. Obtained only for MO calls in scripts. If no "Call Initiation" event was generated, the user setup time cannot be computed.)

Dial End

The event is generated only once for a given interferer in the course of a scan. Furthermore, if interference is detected on several contiguous RF channels, only one event is reported for all of these channels.
