System and method for multi-telecommunication local IP network
First Claim
1. A system for multi-telecommunication over a local IP network, comprising:
- an IP network;
a local IP network;
a plurality of terminals connected to the local IP network, for conducting a call over the local IP network;
a home gateway connected to the IP network and the local IP network, for interfacing between the IP network and the plurality of terminals, assigning an ID and a port to each terminal to differentiate terminals sharing one IP address in processing an incoming call and an outgoing call, and converting IP and port information in a header and payload of a received or transmitted packet according to an assigned ID and port number; and
a gatekeeper connected to the IP network, for performing registration and call connection admission and managing a state of the IP network.

6. A method of initiating a call for multi-telecommunication over a local IP network, comprising the steps of:
-
assigning a port to a first terminal when said first terminal requests a call initiation, and storing information of the terminal;
converting a transmission packet according to the stored information and transmitting the converted transmission packet; and
converting a received packet when the packet corresponding to the stored information is received, converting the received packet according to the stored information, and transmitting the converted packet to said first terminal. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of operating a home gateway for multi-telecommunication over a local IP network, comprising the steps of:
-
determining whether a call connection is requested by analyzing a packet upon receipt of the packet and checking whether the number of connection lines currently sharing the same IP address is greater than or equal to a predetermined number of connection lines, upon request of the call connection;
opening a channel for a second terminal according to an IP and port information of a destination in the packet if a number of connection lines is less than or equal to the predetermined number of connection lines;
converting the packet according to the IP and port information of a first terminal and said second terminal and transmitting the packet; and
denying call connection and performing an error-related operation if the number of the connection lines is greater than the predetermined number of connection lines.

29. A packet receiving method for multi-telecommunication over a local IP network, comprising the steps of:
-
determining whether a call connection to a second terminal connected to the local IP network is requested by analyzing a packet upon receipt of the packet from an IP network;
opening a channel for said second terminal according to the IP and port information of a destination in the packet upon request of the call connection; and
converting transmitted and received packets according to the IP and port information of a first terminal and said second terminal. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A method of conducting a telephone call using one IP address for a plurality of terminals connected to a local IP network, comprising the steps of:
-
determining whether a packet is assigned to the local IP network by a home gateway of the local IP network, upon receipt of the packet from an IP network;
determining whether the packet is for a telephone call if the packet is assigned to the local IP network;
converting the header and payload of the packet according to IP and port information preset for the telephone call, if the packet is for the telephone call, and transmitting the converted packet to a terminal connected to the local IP network;
determining whether the packet is for conventional Internet communication if the packet is not for the telephone call; and
converting the packet according to IP and port information preset for the conventional Internet communication if the packet is for the conventional Internet communication and transmitting the converted packet to the terminal connected to the local IP network. - View Dependent Claims (45, 46, 47)

48. A method of conducting a telephone call using one IP address in a plurality of terminals connected to a local IP network, comprising the steps of:
-
determining whether a packet is for a telephone call by a home gateway of the local IP network, upon receipt of the packet from a terminal connected to the local IP network;
converting the header and payload of the packet, if the packet is for the telephone call, and transmitting the converted packet to an IP network;
determining whether the packet is for conventional Internet communication if the packet is not for the telephone call;
converting the packet and transmitting the converted packet to the IP network; and
registering an IP address and a port number of the packet for new Internet communication if the packet is neither for the telephone call nor for the conventional Internet communication. - View Dependent Claims (49, 50, 51, 52)
