USSD for locating subscriber

Dear colleagues,

Is it possible for the application server to query the location of mobile (cell ID), by contacting mobile directly via USSD?
rather than doing the ATI (Any Time Interrogation) through HLR.

What I mean with direct contact, for sure via USSD gateway that also possible resides on the same machine as app_server:
App_server -> USSD_Gateway -> HLR -> VLR/MSC -> MS

If there is any link related to that, will be very helpful for me.

Thanks
