Title: Consistent user interface for multi-mode mobile terminals
Inventor: HOSSAIN ASIF
IPC: H04M1/724
Filed: 2008-03-17
Abstract: To provide a consistent (i.e., single-mode) user interface in each mode of operation available on a multi-mode mobile terminal, aspects of the user interface used for a second mode (e.g., the CDMA mode) are emulated by the mobile terminal when the mobile terminal is operating in a first mode (e.g., the GSM mode).  Responsive to receiving, while operating in a first mode, an indication of a given user interface interaction, the multi-mode mobile terminal determines the call state. Based on the given user interface interaction and the call state, the multi-mode mobile terminal selects a candidate message corresponding to operation of the multi-mode mobile terminal in a second mode. The multi-mode mobile terminal then converts the candidate message to one or more first-mode messages and transmits the one or more first-mode messages to the MSC at the second wireless network subsystem.
