Software architecture for dual mode phone and method of use

A method for operation of a dual mode wireless communication device, the method comprising:

• initializing the device;
• monitoring first incoming signals to identify a first signal for a first air interface;
• acquiring the first signal to enable a first mode of operation;
• analyzing a system parameter stored in a data storage area on the dual mode wireless communication device;
• determining based on the analysis that a second mode of operation is available;
• monitoring second incoming signals to identify a second signal for the second mode of operation;
• acquiring the second signal to enable the second mode of operation;
• determining that there is no active traffic related to the first mode of operation;
• and
• registering the dual mode device for voice over internet protocol (VoIP) service in the second mode of operation.
