Can i track a user based on the SMS he sends...

Hello,

Is there any provision to capture the Cell ID information in any of the origination messages while a SMS attempt. As far as i know VLR ID is captured in the IDP of SMS for a prepaid subscriber but not sure about the Cell ID.

It will be very helpful if someone can put some light on this issue.

Thanks in advance!!

Hi,

In case of CAMEL in the IDP message for SMS-MO cell ID is present.

Thanks for the reply, i figured out that. But any idea about whether Cell ID is also present in the messages exchanged between SMSC and MSC?

Hi

Only the originating address is present and cell ID is not present. You can check the MAP specification for Forward SM message to confirm

Hi,

thanks again for quick response, so that means i can't track a user via the SMS he makes. Does that apply for USSD also in the same way?
Do you have any idea from where i can a detailed information on USSD and SMSC message flows, some sort of technical specifications etc.

Thanks for the help.

Hi,

I don't think is is possible for USSD as well, You can refer 3GPP TS 29.002 for both USSD and SMS Signalling details. Can't you use an ATI?

Hi,

I suppose by ATI you mean any time interrogation, but actually i was just wondering if we can obtain the location information of a subscriber via SMS or USSD which he originates and not actually enquiring MSC or IN for the cell id, if u can help me in that respect, that will be very helpful.
