    Dear PC!
    On which interface you have done your call tracing and what protocols are subjects in point? In other words, what is your goal? 🙂

    For which events? Mobility management? Call Management? Radio Resourse Management? Or may be you are interested in layer2 events?

    Hi, pc! I don’t understand what you want.
    You may see “the main signals” of MM and CM in 24.008.. and “the main signals” of RR in 44.018.. and “the main signals” of Layer2 protocol on RF interface in 44.005 and 44.006 spec’s.
    BR 🙂

    Hi Pan
    it is like this
    we are calling to many MS, Ex ; land line.you can record all those call in NMS so then we are analzising those signals to pertculer number. so at that time which signals we have to concider.(the which signals should be there of not there)

    pc, from what point of view “main”? For call analysis in some situations you might be need all CC-signaling.

    hi C300G
    to complet the one singal call, these signals should be there.
    What those signals and isthere any importan signals.Ex SDCCH.

    IMHO it would be something like that:
    For basic call CC-tracing:
    SETUP
    DISCONNECT
    RELEASE
    ALERTING
    CALL CONFIRMED
    CALL PROCEEDING
    CONNECT
    CONNECT ACKNOWLEDGE
    EMERGENCY SETUP
    RELEASE COMPLETE

    Less useful:
    START_DTMF
    STOP_DTMF
    STOP_DTMF_ACKNOWLEDGE
    START_DTMF_ACKNOWLEDGE
    START_DTMF_REJECT
    STATUS
    STATUS_ENQUIRY
    FACILITY
    HOLD
    HOLD_ACKNOWLEDGE
    HOLD_REJECT
    RETRIEVE
    RETRIEVE_ACKNOWLEDGE
    RETRIEVE_REJECT

    Rare:
    PROGRESS
    CC_ESTABLISHMENT
    CC_ESTABLISHMENT_CONFIRMED
    RECALL
    START_CC
    MODIFY
    MODIFY_COMPLETE
    MODIFY_REJECT
    USER_INFORMATION
    CONGESTION_CONTROL
    NOTIFY

    HI C300G
    Thank you Very Much.If you can give me like this
    1)sdcch
    2) Paging
    3)FACH…………….so on.
    If you can explain how above CH and signal beheviaer with the call that’s very sound to me to do the optimization.

    I don’t quite understand what should I give, sorry.
    Are You asking about channel allocation for basic call or what?
