Hardware activation of dual USIM multimode mobile terminal
Certain aspects of the present disclosure relate to a method for hardware activation of dual USIM TD-SCDMA multimode mobile terminals. The technique effectively provides for efficient power consumption. In one aspect, a mobile terminal may register dual mobile identifiers on a first radio access technology (RAT) using a first hardware module. If a call is set up, the mobile terminal activates a second hardware module and registers the unused mobile identifier with the second RAT.

initiating a call with the first mobile identifier using the first module such that the UE transitions from the idle mode to a connected mode;
activating the second module in response to the call initiation; and
registering the second mobile identifier with the second RAT using the second module while maintaining the call with the first mobile identifier using the first module.
