1. A mobile communication terminal for executing a mobile messenger service, the terminal comprising:
- a control unit;
a wireless communication unit for transmitting, via a Short Message Service (SMS) server through a mobile communication network, an SMS invitation message that includes information for performing the mobile messenger service with a counterpart mobile communication terminal via a packet data communication network distinct from the mobile communication network, such that the information for performing the mobile messenger service includes information for identifying the mobile communication terminal with respect to the packet data communication network;
a packet data communication network interface unit for providing an interface with the packet data communication network according to the information included in the SMS invitation message transmitted via the SMS server, receiving, from the counterpart mobile communication terminal, a reply to the SMS invitation message indicating acceptance of the mobile messenger service through the mobile messenger service via the packet data communication network according to the information identifying the sender of the SMS invitation message with respect to the packet data communication network included in the SMS invitation message, and sending a first transmission packet of image data to the counterpart mobile communication terminal via the packet data communication network at a specified period under control of the control unit;
an image acquisition unit for periodically obtaining the image data by determining whether a predefined transmission period for transmitting the obtained image data has elapsed, under control of the control unit in response to a request for image transmission during execution of the accepted mobile messenger service; and
a transmission packet creation unit creating the first transmission packet of the image data under control of the control unit,wherein image data is obtained and a second transmission packet of the image data is created when the predefined transmission period has elapsed, and a time when the period elapses is waited for when the predefined transmission period has not elapsed.

Abstract
Provided are a mobile communication terminal and a method capable of transmitting an image during the execution of a mobile messenger service. A host terminal acquires image data in response to a request for image transmission and creates a first transmission packet of the image data. The first packet is sent to a client terminal through a packet data communication network at a specified period. Additionally, when receiving a second transmission packet of image data from the client terminal, the host terminal decodes and displays the received second packet.
