US 2009/0154672 A1 · PATH SETTING METHOD OF INTEGRATED SWITCH FOR SIMULTANEOUSLY PROVIDING REAL-TIME MOBILITY OF IP ADDRESS AND TELEPHONE NUMBER

Abstract

Provided is a path setting method of an integrated switch for simultaneously providing real-time mobility of an IP address and a telephone number. The path setting method of an integrated switch constructs an information pair of the telephone number and the IP address and transmits a voice call and a data packet using a home agent (HA) and a foreign agent (FA) for providing mobility in a mobile network easily and rapidly when a telephone terminal and an IP data terminal are moved. According to the path setting method of an integrated switch, the telephone terminal and the IP data terminal can use original addresses thereof when the telephone terminal and the IP data terminal are moved to a network area having a number system different from that of the network area to which the telephone terminal and the IP data terminal originally belong.

A method of providing services to terminals using an integrated switch, the method comprising:

transmitting an identifier of a telephone terminal of a subscriber in response to an identifier request signal received from the integrated switch and receiving a telephone service from the integrated switch through the telephone terminal;
detecting a silent period from a telephone service channel of the telephone terminal;
and
transmitting an IP service registration request message including a care-of-address (CoA) using the silent period of the telephone service channel to the integrated switch, receiving a registration response message including an approval response from the integrated switch, and receiving an IP data terminal service from the integrated switch through a data terminal of the subscriber.

A path setting method of an integrated switch for simultaneously providing real-time mobility of an IP address and a telephone number, the path setting method comprising:

receiving a registration request message including a telephone number of a telephone terminal and an IP address of an IP data terminal from a first integrated switch located in a first network area in which the telephone terminal and the IP data terminal are originally located when the telephone terminal and the IP data terminal are moved to a second network area;
determining whether the telephone number of the telephone terminal and the IP address of the IP data terminal are included in an internal list of a second integrated switch located in the second network area;
and
providing the telephone service to the telephone terminal by the second integrated switch and providing the IP data service to the IP data terminal in a silent period of a telephone service channel of the telephone terminal when the telephone number of the telephone terminal and the IP address of the IP data terminal both are included in the internal list of the second integrated switch.
