Hybrid mobile communication terminal and method of acquiring system for data service in hybrid mobile communication terminal

Abstract

A hybrid mobile communication terminal includes a mode setting unit which sets a High Data Rate (HDR) power save mode and an indicator indicating the HDR power save mode when data service cannot be provided through a CDMA2000 1x EVDO (Evolution Data Only) system; and a data communication unit which attempts to acquire a CDMA2000 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit. A method for acquiring a system for data service includes: setting an HDR power save mode and an indicator indicating the HDR power save mode when the data service cannot be provided through the EVDO system; determining whether the indicator has been set upon acquiring a system for the data, service; and attempting to acquire the 1x system or the EVDO system according to whether the indicator has been set.

1 . A method for acquiring a first system supporting low-speed data service or a second system supporting high-speed data service, comprising:
 setting a power save mode and an indicator indicating the power save mode if data service cannot be provided through the second system;   determining whether the indicator has been set upon receiving a request for data service; and   attempting to acquire the first system or the second system according to whether the indicator has been set.   
   
   
       2 . A hybrid mobile communication terminal that can acquire a first system supporting low-speed data service and a second system supporting high-speed data service, comprising:
 a mode setting unit to set a power save mode and an indicator indicating the power save mode if data service cannot be provided through the second system; and   a data communication unit to acquire the first system or the second system according to whether the indicator has been set.   
   
   
       3 . A method for acquiring one of multiple systems for data service, each system having a priority for providing the data service, the method comprising:
 setting a power save mode and an indicator indicating the power save mode if the data service cannot be provided through a first system having a highest priority;   determining whether the indicator has been set upon receiving a request for data service; and   attempting to acquire the first system or a second system having a lower priority than the first system according to whether the indicator has been set.   
   
   
       4 . A hybrid mobile communication terminal that can acquire at least one of multiple systems for data service, each system having a priority for providing the data service, comprising:
 a mode setting unit to set a power save mode and an indicator indicating the power save mode if the data service cannot be provided through a first system having a highest priority; and   a data communication unit to acquire the first system or a second system having a lower priority than the first system according to whether the indicator has been set.
