4.5.7. Call Trace Testing Function

Mobile Call Trace Function traces the process of call setup for the MS, surveillance of

the status after the call setup, the process of call release, and displays the content

visibly to BSM after BSM of User’s terminal designates a Mobile Station(MS) at

random by using a value of MSIN(Mobile Station Identification Number). . The

designated Mobile Station(MS) can trace the originating call or terminating call that

was set up by the user and if necessary, it sets up Markov call(i.e., a terminating

Markov call by paging) for tracing. Mobile call tracing can be performed to all kinds of

calls(Voice Call, Data Call, HandOff Call) and can designate maximum two calls

simultaneously for tracing. Information provided upon call tracing is as follows:

Tracing Information when Call is set

Resource of Call to be set

System Resource: BSC No, BTS No, Sector No, PN Offset

Attributes of Call: IMSI, ESN, Service Option, Call Type(Voice Call originating, Voice

Call terminating, DATA Call initial set, DATA Call Reactivation by MS, DATA Call

Reactivation by Network), Terminating number

BTS Resource: CDMA CH(Frequency) No, TC No(RCP#, MCPA#, CE#),

Code CH(Walsh code), Frame Offset

BSC Resource: SLP, VCE Number, CIC(Circuit Identifier Code)

Setup Process

Message display between processors during Call Setup: Visible Display of Call Flow

During Call Setup, display RTD(Round Trip Delay) value and calculated distance by

using this.

When Call Failure occurs, display reason value and its meaning

Call Set Time by section

Tracing Information at the phase of calling after Call Setup: Tracing and Display at

intervals of 1 ~ 5 seconds.
