    How do I map MCC/MNC/LAC into a real name

    Hi,

    I've successfully got gsm_location() results by help from this forum. Now, I want to know, for the 4-tuples the gsm_location() returns, how do I discover its meaning? Is there a lookup dictionary? Thanks.

    Hi,
    gsm_location provides you the id number only. It doesnt return a name ,only solution is create your own look table.
    Thanks.

    hello narke

    from gsm_location function returns you 4 strings i.e.
    MCC i.e. mobile country code
    MNC i.e. mobile network code
    LAC i.e. Location Area Code
    CellId i.e. the exact code for the BTS of that particlular area.

    Its really very difficult to map the location name from the cellid we already had lots of discussion in this forum please search for that.

    Enjoy Pythoning

    And the MCC list (mapping of to country names) you can get from ITU:
    http://www.itu.int/dms_pub/itu-t/opb...2007-PDF-E.pdf

    Same with MNC (mapping to operator/carrier names):
    http://www.itu.int/dms_pub/itu-t/oth...030002PDFE.pdf

    I think the LAC is operator/carrier (network) specific.

    Operators/carries might use for LAC country specific postal codes (zip codes, postal numbers or whatever is the local practice in each country). And if they are postal codes, check with the local postal authorities as to what codes are valid for which countries and what areas/regions they cover. And if the operator/carrier doesn't use postal codes, you have to ask them what they use. So, you'd have to check with every operator/carrier in every country as to what they encode in the LAC.

    The Cell ID is also operator/carrier (network) specific.

    Note also that the so called MVNO's (Mobile Virtual Network Operators) use somebody else's network (and might be using different networks in different areas/regions). In other words, you need to be aware of which operator doesn't have their own network, and whose network they're really on.

    With 200+ countries and 1000+ network operators/carriers, it shouldn't take you more than a couple of years to collect the info (assuming they tell you), if you start calling or writing them letters now.

    Note of course that new countries come and old countries cease to exist almost every year. Same with new operators/carriers appear or old go out of business or merge with others.

    And occasionally also countries redo/change their postal codes, too at least when postal officies are merged, etc. (sometimes the whole country level numbering/encoding system might change, too).

    In other words, the any information you collect is only a snapshot in time, and will gradually become old/erroneus, if you don't keep it up to date.

    Thank you very much! Now I understand LAC is hard and cellspotting have not yet supported s60 3rd edition by far.
