    Dear, Dariush!
    There is no mandatory protocol stack between BSC and CBC in GSM. It is vendor dependent. In 03.49 you may find out example protocol stacks. See also 03.41 for CBS.

    Dear, Pan

    Thanks for your reply actually i read these standards but our application did’t work with such protocol stack which came inside Recommendation so that we need exact Protocol used by Simens So Any help or advice regarding Internal protocol used by siemens will be helpful.

    Hi to all,

    Can I ask your help? We have a project for CBC on two different vendor Ericsson and Alcatel.

    What program to interface the BSC and I can send CBC on to it?

    The protocol stacks are (good luck in redrawing them “horizontally” ):

    – BSC
    SMS−CB
    X.25
    XOT
    TCP/UDP
    IP
    Link(802.3)

    – IP/X25 Router
    X.25 —————— X.25
    XOT —————— LAPB
    TCP/UDP ————— SERIAL LINK
    IP
    Link(802.3)

    – CBC
    SMS−CB
    X.25
    LAPB

    The EIM-R is the application process which manages 9130 BSC Evolution external communication with the CBC and the OMCR.

    Hello, Mehran!
    Siemens BSC supports two options for interconnect with CBC:
    – X.25 protocol stack
    – IP protocol stack.
    They are not proprietary protocols.

    HI,Pan

    Thanks for your reply but inside the bsc TED they mentioned they have used proprietary Protocol.that why we need it to implement our application.

    Dear, Dariush!
    There is quot from Siemens BR9 description (OMN:BSC):
    The BSC is interfaced with the following Network Management systems:
    …….
    b) the Cell Broadcast Centre to support all GSM specified cell broadcast service primitives.
    …..
    In order to manage the interfaces toward these network elements, two different level 3
    protocols are supported by the eBSC:
    – The X.25 protocol;
    – The IP protocol
    with regards, Pan.

    Dear All,

    I am trying to broadcast a message form CBC application to ALU BSC.
    The problem is that i am able to broadcast only on channel 50, but if i try and broadcast on any other channel i am getting an error “bss capacity exceeded”.
    Is there any configuration required to be done in ALU BSC to enable the broadcast for different channel.

    Kindly help

    Hi Sonit

    Plz check if the Channel 51 is created or not in the respective BSC.

    Regards
