Often there is a need to temporary assign an additional phone existing phone numbers to a cell phone. An example would be to assign your mobile cell phone to a hand free cell phone in a rental car. This would allow a user to have a common phone number and account and still be able to use a multitude of different physical devices. Every cell phone has an unique identifier within the cell phone. The MSO (Master Service Office) maintains a table which matches a telephone number to the cell phone unique ID. When you dial a number the packet goes to the MSO and the MSO translates the packet and substitutes the unique identifier for the phone number. So for this disclosure we allow the MSO to assign two different unique cell phones to a common phone number. One is the permanent cell phone always associated with the phone number. The other is a temporary cell phone which only lasts until the user disengages. First we define a new command structure that allows a user to temporary change a cell phone to their permanent number. It can be as simple as a multiple key sequence and eventually can be added as a function key to new cell phones. For control reasons a user would initiate the change from their permanent phone number. So hit the key sequence and than a query can ask for the permanent phone number of the cell phone you want to switch your number to. This function could also be password protected for added control. The MSO will now assign two cell phones to the same phone number. Both phones would ring and the first to pick up wins. A variety of methods can be used to remove your permeant phone number from the secondary device. It could be a time limit which you set when you set up the number, a redo of the key structure, a query when you use your permanent phone reminding you have also assigned your number to a secondary device, etc. The cell phone companies will like this idea as they can charge money for this service. 1
