Sending Location Update Request

  • I am fairly new to dialogic and ss7 so bear with me, but as I understand it from the MAP PM, Update-Location requires these 3 parameters:

    IMSI, MSC Number, and VLR Number

    Along with these 3 parameters, we need a Called Party address (ie a destination) and as I understand it, this consists of the called party digits being the MGT version of the IMSI with an ISDN/mobile numbering plan (0x07) and HLR subsystem (0x06).

    From here, it will know to route the location update to the HLR of the called party who's carrier is identified by the MGT (if I understand this right)

     

    When I tried creating and sending this message, I get the following from gctload:

    SCPP Maintenance event : SCPEV_RTF_TTYPE

     

    From what I understand (further), this means dialogic dropped the message (it never went on the wire) because of some failed validation dialogic does before sending the message out.

     

    Can someone clear up this message for me? Why is dialogic dropping it?

     

    Thanks ahead of time!

    Correct.

    The SCPEV_RTF_TTYPE means "Routing failed, no translation for specified global title type".

    Perhaps global title translation for the MGT haven't been configured or the translation type field in the SCCP Called Party Address is wrong. Check SCCP PM and this article

    Hope this helps.
