    Hi All,

    A party is in conversation with B party. During this time C party calls the B party and C listens the call waiting announcement.

    Consider that all 3 subscribers are in the differnet MSC.

    During this time,how many airinterface channels are seized by B party.

    My question is will there be any assignment request from the B party BSC to the MSC for the new call waiting call??(hope u guys understand my question)

    Call holding:-
    —————

    When B party holds the ongoing call of A party and starts the conversation with C party, During this time how many channels are siezed?

    As I know there is no change in the air interface – one call or multiple calls in a conference call doesn’t make any difference.

    the orignating mobile is already on TCH (cf. message flow, message “ALERTING”)

    (is that what you meant by call waiting ?)

    Thank you Pix for the answer,
    it means that signaling can use as well TCH
    I didn’t know that
    If I take the example of an SMS,
    SDCCH is used on Idle mode, and SACCH on Active mole. I believed that it was the same for the call waiting signaling (I believed that the signal that tell there is an other call go through SACCH) but it seems not.

    actually the alerting is on the FACCH, which is a “sub” channel of the TCH.

    glad i could help 🙂

    Thank you Pix,
    I should have known this,

    In fact it s logical
    because SACCH is just reserved for measurement and SMS

    so the alerting is on the Hand over channel :FACCH

    Regards
