Hybrid mobile communication terminal and method of acquiring system for data service in hybrid mobile communication terminal
View Patent ↗Disclosed are a hybrid mobile communication terminal and a method of acquiring a system for data service in the hybrid terminal. The hybrid terminal includes a mode setting unit which sets an HDR power save mode and an indicator indicating the HDR power save mode when data service cannot be provided through the EVDO system; and a data communication unit which attempts to acquire the 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit. The method 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 of acquiring a system for data service in a hybrid mobile communication terminal that can acquire a 1x system supporting voice and low-speed data services and an EVDO (Evolution Data Only) system supporting a high-speed data service, the method comprising the operations of:
setting an HDR (High Data Rate) power save mode and an indicator indicating the HDR power save mode if the data service cannot be provided through the EVDO system;
determining whether the indicator has been set upon receiving a request from a user for a data service; and
attempting to acquire the 1x system or the EVDO system according to whether the indicator has been set.
2. The method of claim 1 , wherein the HDR power save mode prevents attempting to acquire the EVDO system according to slot period.
3. The method of claim 2 , wherein the hybrid mobile communication terminal attempts to acquire the 1x system if the indicator has been set, and attempts to acquire the EVDO system if the indicator has not been set.
4. The method of claim 1 , further comprising the operations of:
attempting to acquire the EVDO system at regular intervals if the HDR power save mode is set; and
releasing the HDR power save mode and the indicator after the EVDO system has been acquired.
5. The method of claim 2 , further comprising the operations of:
attempting to acquire the EVDO system at regular intervals if the HDR power save mode is set; and
releasing the HDR power save mode and the indicator after the EVDO system has been acquired.
6. The method of claim 3 , further comprising the operations of:
attempting to acquire the EVDO system at regular intervals if the HDR power save mode is set; and
releasing the HDR power save mode and the indicator after the EVDO system has been acquired.
7. A hybrid mobile communication terminal that can acquire a 1x system supporting voice and low-speed data services and an EVDO (Evolution Data Only) system supporting a high-speed data service, comprising:
a mode setting unit to set an HDR (High Data Rate) power save mode and an indicator indicating the HDR power save mode if a data service cannot be provided through the EVDO system; and
a data communication unit to acquire the 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit.
8. The hybrid mobile communication terminal of claim 7 , wherein the HDR power save mode prevents attempting to acquire the EVDO system according to slot period.
9. The hybrid mobile communication terminal of claim 8 , wherein the data communication unit attempts to acquire the 1x system if the indicator has been set by the mode setting unit, and attempts to acquire the EVDO system if the indicator has not been set.
10. The hybrid mobile communication terminal of claim 7 ,
wherein the data communication unit attempts to acquire the EVDO system at regular intervals if the HDR power save mode is set by the mode setting unit, and
the mode setting unit releases the HDR power save mode and the indicator after the EVDO system has been acquired by the data communication unit.
11. The hybrid mobile communication terminal of claim 8 ,
wherein the data communication unit attempts to acquire the EVDO system at regular intervals if the HDR power save mode is set by the mode setting unit, and
the mode setting unit releases the HDR power save mode and the indicator after the EVDO system has been acquired by the data communication unit.
12. The hybrid mobile communication terminal of claim 9 ,
wherein the data communication unit attempts to acquire the EVDO system at regular intervals if the HDR power save mode is set by the mode setting unit, and
the mode setting unit releases the HDR power save mode and the indicator after the EVDO system has been acquired by the data communication unit.
