Method of providing PoC service in mobile communication system

Abstract

A method of providing a PoC service service in a mobile communication system is disclosed, by which a user's sensory duration can be reduced in case of switching a status of a traffic channel between a user equipment and a mobile communication network to an active mode from a dormant mode in the mobile communication system such as a CDMA network. The present invention includes a first step of transmitting the PoC service data from a first user equipment in the dormant mode via a short data burst, a second step of allowing the user equipment to enter an active mode via a traffic channel connection after completion of the first step, a third step of transmitting a reception acknowledgement signal (ACK) from a second user equipment having received the PoC service data via the short data burst, and a fourth step of receiving the reception acknowledgement signal (ACK) via a traffic channel.
