METHOD FOR CONTROLLING MOBILE COMMUNICATION TERMINAL TO IMPROVE RECEIVING/SENDING VOICE CALL AND MOBILE COMMUNICATION TERMINAL USING THE SAME

摘要

The control method of the mobile communication terminal is to fall back to the mobile communication terminal connected to the PS network, the CS network voice during the whole process of the call in progress and storing the collected information to the PS network , when a voice call is terminated comprising: receiving a switch command from the PS network, the CS network , according to the PS network switching command at least one of information about the PS network If one of the step of determining whether or not to switch the PS network on the basis of the information , and the PS network switch comprises the step of switching to the determined PS network from the CS network . Accordingly , it is determined in advance by collecting the potential of the PS network switches based on the information on the stored PS network and attempts to transition to a PS network according to the determination result , CSFB registration delay and after failure of a PS network can be prevented . ;
