The present invention relates to a mobile communication terminal and a communication method using the same.

With the breakthrough of mobile communication and the expansion of communication network, a wider variety of services and applications using mobile phones are being provided. In addition, the needs of users are diversified to extend beyond simple call services to location services, multimedia services, and PTT services. In particular, the PTT service supports various additional functions such as instant messenger and status display as well as group call and voice call.

Currently, the establishment of a standard for push-to-talk over cellular (PoC) service that uses the PTT (Push To Talk) concept using a mobile communication network has been actively discussed. One of the characteristics of the PoC service distinguished from the existing mobile communication service is that the user belongs to a plurality of sessions and can make a call while moving between sessions as needed. The requirement that a user be able to talk while moving between multiple sessions is specified in the requirements of the Open Mobile Alliance (OMA), an organization that defines mobile services.

Presence generally refers to the presence of a device and an application for mutual communication that indicates that a communication channel is open (logged-in or active on a network) and availability availability, and the user's communication preferences.

In general, presence information is only passively available information. That is, the current state of the other party is only in an on-line state, an off-line state, or a busy state. Therefore, the use of services based on this information is entirely up to the user's decision. In other words, if the party's current status is marked as offline or busy, you must wait indefinitely for the other party to be online before you can make a voice call, video call, or chat with the other party.

In addition, the presence information of the other party manually informs of the change. In order to confirm the presence status of the other party in the idle state due to the use of the terminal because the change of the icon or the like is informed, the display unit of the terminal is activated by pressing an arbitrary button . Therefore, the presence information of the other party can not be confirmed when the display unit of the terminal is not activated.

An object of the present invention is to provide a mobile communication terminal positively responding to fluctuation of presence information of a counter party and a communication method using the same.

Another object of the present invention is to provide a mobile communication terminal and a communication method using the same, which can easily set a session for a call connection by recognizing the change of presence of the other party.

Yet another object of the present invention is to provide a mobile communication terminal capable of recognizing a change of presence of a counterpart designated by a user in real time and a communication method using the same.

Yet another object of the present invention is to provide a mobile communication terminal and a communication method using the mobile communication terminal, which can avoid an unnecessary repeated session connection request to the other party unable to establish a session connection.
