    Can anyone explain the GSM cell id format? What do the digits mean?

    Thanks.

    CI (cell identity) = xXYYZ, where
    xX: BSC number
    YY: BTS number within the BSC
    Z: Cell number within the BTS
    Z=0 for the omni site, Z=(1-3) for the sectoral site.

    CGI (cell global identification) = MCC-MNC-LAC-CI, where
    MCC=AAA: mobile country code
    MNC=BB: mobile network code
    LAC=ccCCC: location area code
    CI: cell id (see above)

    For example, CGI = 452 02 341 5012

    452=MCC of Vietnam
    02=MNC of VinaPhone network
    341=LAC
    5012=CI
    This is the second cell of the BTS-1 in the BSC-5.

    Thanks Nguyen. I have one other question. Part of the overhead messaging contains Cell Allocation Information and Neighbor Cell Information. Each has a Number of Channels and then a channel list. Do you know what the differences are? I understand the neighbor list, but I’m a little confused on the cell allocation list.

    Thanks.

    I know some web site that provide the training and certifications: http://www.inacon.com, http://www.wraycastle.com, http://www.pmcg-consultancy.co.uk, etc. However you cannot download any document from these sites.

    If anyone knows where to download GSM technical/training document for free, pls kindly advise.

    hi,

    no, the LAC and Cell ID are unique values that are not “contained” into lat/long, MNC and MCC.

    Is it normal to find a gsm Cell without any code? No cid no mcc no mcc or any other code. I think it could be a gsm spy Cell.
