Hardware/Device to capture Mobile Numbers (IMSI) remotely
I am looking to build a hardware equipment or device with the following function:
1. When a person carrying a mobile phone is in the vicinity of this device or hardware, it will be able to detect the signal from it and decipher the information from that signal to relay the mobile number of that handset.
2. My understanding is that the information relayed from the mobile phone signal contains the IMSI information which in turn contains the mobile phone number of that handset.
Any information on how to build a device like this will be appreciated.

Well I wouldnt know how to clone a phone or what cloning a phone means. It is actually meant for notification or alerts to the mobile users who are in the vicinity. No ill intentions intended.

This solution is only available to members.

The only entity that knows which mobiles are in the vicintyis called as the VLR (Visitor Location Register) which is linked to a mobiles serving MSC (mobile Switching Centre)
You cannot tap the paging messages that are sent by the mobile or by the towers as they are secure.
If you want to do this kind of stuff, you will need to connect to the service provider and then through the service provider, you will be able to send messages to the subscribers. (Even in this case, a service provider will rarely allow you to send messges to users area-wise as this is SPAM). You need to know the numbers of the users you intend to send messages to.
In general, what you are intending to so is not possible due to the dynamics of the GSM network and the way the SMS systems work. It will require a lot of integration with the SMSC, HLR and VLRs of the service provider and the providers (atleast the sane ones) DO NOT provide access to these components!!

To keep it simple: Thanks god nobody can spy my IMSI without using of very expensive hardware. If you are a police officer and go in contact with me by email, I will give you maybe further details, but I never would like to post it online. If you visit my profile, you will get an idea where you can reach/meet me.

Unless you work at a mobile phone company, the only use for this data is to illegally clone a phone.
If you do work at a mobile phone company, then your employer supplies the tools that you need.
I suggest that no experts give advice on this, and that this question be deleted.
