a visitor identifying and communicating proxy means for requesting a session connection to one of the visitor identifying and communicating terminals, selected by the resident, based on the contact addresses according to the detected location of the resident by the terminal recognizing means when the bell activation event is occurred, exchanging voice and image of the visitor and voice of the resident between the video door phone device and the selected terminal through a session channel connected by the resident'"'"'s allowance of the session connection request, and releasing the session by a request of the selected terminal;

wherein each of the visitor identifying and communicating terminals includes;

a visitor communication terminal application controller for registering and updating location information of a terminal, transmitting and receiving a session initiation protocol (SIP) message, and processing a real-time transport protocol (RTP) packet;

a user interface processor for sensing and processing an event inputted from a user and interacting with the visitor communication terminal application controller; and

a multimedia interface processor for encoding voice data inputted from a microphone, decoding received visitor'"'"'s voice/image data, and outputting the decoded voice/image data.

2. The system for providing a service identifying a visitor and communicating a visitor as recited in claim 1, wherein the visitor identifying and communicating terminals includes a wireless communication terminal,

the wireless communication terminal having:

the visitor communication terminal application controller for registering and updating location information of the terminal, transmitting and receiving the session initiation protocol (SIP) message, and processing the real-time transport protocol (RTP) packet;

the user interface processor for sensing and processing the event inputted from the user and interacting with the visitor communication terminal application controller;

the multimedia interface processor for encoding voice data inputted from the microphone, decoding received visitor'"'"'s voice/image data, and outputting the decoded voice/image data; and

a terminal recognition controller for processing a terminal recognition request message of the terminal recognizing means.

3. A method for providing a service identifying a visitor and communicating a visitor using a home network, comprising the steps of:

a) at a home gateway device, determining whether a resident is home or not through a message communication between a home gateway and the resident'"'"'s wireless communication terminal in real time when a bell activation event is occurred by a visitor;

b) at the home gateway device, requesting a session connection to one of in-house visitor identifying and communicating terminals, selected by the resident, based on a contact address when the resident is home according to the determination of the step a);

c) at the home gateway device, transmitting an image of the visitor from the video door phone to a resident-selected visitor identifying and communicating terminal through a session channel established by the resident'"'"'s allowance of the session connection request; and

d) at the home gateway device, releasing the connected session by a request of the resident-selected visiting identifying and communicating terminal, wherein in the a), in order to determine whether the resident is home or not in real time through the message communication between the home gateway and the resident'"'"'s wireless communication terminal, the wireless communication terminal dynamically updates a receiving IP address to the home gateway device based on an updating method when the wireless communication terminal moves among packet data servicing nodes (PDSN) in a wireless communication network,

the updating method includes the steps of;

at a first packet data serving node (PDSN) having a plurality of address resources, allocating an internet protocol (IP) address to a wireless communication terminal connected to the first PDSN;

at the wireless communication terminal, registering a contact location to the home gate way device by using corresponding address information; and

at the wireless communication terminal, updating a contact address of own by transmitting a location change request message to the home gate way device when the wireless communication terminal moves to an area covered by a second packet data serving node (PDSN) and the second PDSN allocates a new IP address to the wireless communication terminal.

4. The method for providing a service identifying a visitor and communicating a visitor using a home network as recited in claim 3, wherein the step c) further includes a step of:

at the home gateway, transferring voice of the visitor and voice of the resident between the resident-selected visiting identifying and communicating terminal and the video door phone device through the session channel.

5. The method for providing a service identifying and communicating a visitor using a home network as recited in claim 3, further comprising the steps of:

e) at the home gateway device, activating a recording function according to a request of the resident-selected visiting identifying and communicating terminal;

f) at the home gateway device, outputting an announcement recorded according to a recording function setting to the video door phone device when the bell activation event is occurred by the visitor, and receiving and storing voice/image of the visitor from the video door phone device; and

g) at the home gateway device, transmitting the stored voice/image of the visitor to the resident-selected visitor identifying and communicating terminal by the resident'"'"'s request.

6. The method for providing a service identifying and communicating a visitor using a home network as recited in claim 3.

7. A method for providing a service identifying and communicating a visitor using a home network, the method comprising the steps of:

a) at a home gateway device, determining whether a resident is home or not in real time through a message communication between a home gateway and the resident'"'"'s wireless communication terminal when a bell activation event is occurred by a visitor;

b) at the home gateway device, checking whether a contact address of out-house visitor identifying and communicating terminal is registered or not, and requesting a session connection to a contact address of the out-house visitor identifying and communicating terminal or a contact address of the wireless communication terminal when the resident is not home according to the determination of the step a);

c) at the home gateway device, transmitting an image of the visitor from the video door phone to a resident-selected terminal between the out-house visitor identifying and communicating terminal and the wireless communication terminal through a session channel established by the resident'"'"'s allowance of the session connection request; and

d) at the home gateway device, releasing the connected session by a request of the resident-sejected terminal

wherein in the a), in order to determine whether the resident is home or not in real time through the message communication between the home gateway and the resident'"'"'s wireless communication terminal, the wireless communication terminal dynamically updates a receiving IP address to the home gateway device based on an updating method when the wireless communication terminal moves among packet data servicing nodes (PDSN) in a wireless communication network,
