Abstract:
1. A method for operating a wireless user equipment (UE) device, the method comprising: operating in a discontinuous reception (DRX) mode according to each of a first wireless communication technology and a second wireless communication technology using a single radio, wherein the first wireless communication technology is CDMA2000 1xRTT, wherein the second wireless communication technology is LTE; determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second wireless communication technologies; obtaining a new IMSI over the air via one of the first wireless communication technology or the second wireless communication technology in response to determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second wireless communication technologies; activating the new IMSI to change the IMSI of the UE in response to determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second wireless communication technologies; determining new wakeup times according to DRX cycles of each of the first and second wireless communication technologies, wherein the new wakeup times are based on the changed IMSI; and operating in the DRX mode according to each of the first wireless communication technology and the second wireless communication technology using the single radio and using the new wakeup times.
