Send a text message to the phone and it would surely go out of standby for a brief period of time.

or

If you have a cellphone jammer, try to jam the phone even if it is in standby.  It will probably loose its connection to the network as it wont be able to listen into the network beacon (I forgot what specific channel its called) and it will be forced to re-register to the network.

you are right - when jammed, a GSM phone will try to reestablish the connection and when it does that, there will be signal emitted from the phone.
You could try to detect that signal.

you can use the electrosmog meter tools in : www.cornetmicro.com
every few minutes the GSM phone will contact base station with very short burst signal to let the base station know that it is alive. you need a very fast meter to catch it.  the tool on the above website has a histogram to record the previous 32 measurement events. and it  has very fast response  to capture the digital RF bursts.

With my GSM phone, I think it was something like every half hour or so. To know what was happpening, I kept it close to an FM receiver which was susceptible to the GSM traffic (if my mobile phone was kept close to it) while listening to music. The characteristic motor-boating sound was there, but I do not think that this will be sufficient to locate the phone.

Intentionally jamming the reception and forcing transmission seems to be the way, as mentioned in previous posts.
