ABSTRACT:
Disclosed is a method for connecting a phone call during a Push To Talk (PTT) call traffic in a mobile communication system. The method comprises the steps of searching for a subscriber information of a selected current subscriber from both a PTT subscriber information and a subscriber group list, if a predetermined phone call key has been input; determining if the subscriber information of the selected current subscriber which has been searched from the PTT subscriber information and the subscriber group list is matched to a subscriber information stored in an address registry to confirm the matched subscriber information of the address registry; and terminating the PTT session of the PTT call traffic, connecting the phone call to the selected current subscriber's phone number based on the matched subscriber information of the address registry to perform the phone call traffic.
