Initial Provisioning of a Cellular Device over the Air

      Disclosed is a method for automatically programming the Name
Address Module (NAM) of a newly-purchased cellular telephone or
cellular modem to allow subsequent cellular operation.

      The Figure is a schematic diagram showing operation of the
method in a cellular network.  The cellular device 1 communicates
with a cellular station 2 over an airlink 3, which carries two
different functions---a user bearer (voice) channel and a command
channel.  It is possible to make outgoing calls from the device 1 to
the cellular station 2 when the device has not been assigned a
telephone number.  Certain parameters are received from the control
channel when the device 1 powers on.  While these parameters,
together with a unique Electronic Serial Number (ESN), are sufficient
to originate a call without an assigned mobile telephone number,
calls cannot be sent from the cellular station 2 to the device 1.

      With the presently-disclosed method, the modem firmware 4 of
device 1 accepts data from an on-board application 5, running on an
operating system 6.  The modem firmware also provides data to the
application 5, as messages are delivered across an API Application
Program Interface 7.  During initial power-on, before device 1 has
been provisioned, application 5 requests the ESN from the modem
firmware 4.  The application then instructs the modem to place a
regular voice channel call to cellular network ho...
