    hello,

    class-C devices are pure packet device, they cannot make call. (like a EGPRS-dongle for the computer, etc)

    what do you mean by “class C” ?

    your problem looks like the combined LA/RA update is not working. Maybe the VLR does not receive the periodic LU from the MS.
    Therefore the MS are detached from the VLR.

    regards

    Thanks for answer, Pix.
    MS Class-C, defined in 3GPP TS 22.060 , can be used for packet and circuit.
    Currently i’m testing with Samsung SGH-S500, which is Class-C device, it can associate with SGSN and MSC (combined LA/RA update), but after 3-4hrs it can not make or receive any calls.
    Thanks

    Pls do 3G handsets have service classes that use different classes from GPRS?

    ThanhNV,

    ooops… thanks for the info 🙂

    Well, anyway, I can’t help you about this… Can you check in the VLR what is happening to these MS after 3 or 4 hours ?

    those docs could give you more info…

    3GPP 23.060
    29.016
    29.018
