Method for Controlling Hybrid Mode in CDMA Mobile Communication System and Method for Changing Hybrid Mode of Mobile Communication Terminal Using the same

摘要

The present invention relates to a hybrid mode control method in a code division multiple access mobile communication system for controlling a hybrid mode switching cycle of a mobile communication terminal and a hybrid mode switching method in a mobile communication terminal using the same.;When the 1x EV-DO system receives the call connection request message transmitted from the mobile communication terminal, the present invention provides a traffic channel allocation message including a data slot cycle index (Data_Slot_Cycle_Index) field value indicating a 1x system switching cycle condition of the mobile communication terminal. A first step of transmitting to a mobile communication terminal; And a system parameter message including a selective hybrid mode (Selective_Hybrid_Mode) field value indicating whether the 1x system switches to the 1x system according to the data slot cycle index field value when the mobile communication terminal is in the EV-DO traffic state. Including the second step, since the hybrid mode switching period of the mobile communication terminal can be controlled, there is an advantage that the data transmission rate can be improved and call disconnection phenomenon can be reduced during EV-DO traffic.
