Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

In the present invention, when subscriber A attempts to make a voice call to subscriber B in a network so as to easily access the other party's IP multimedia information, the subscriber automatically sends IP subscriber's IP multimedia information to subscriber B, and subscriber B By automatically sending information to subscriber A, subscribers can easily access the other party's IP multimedia information.

FIG. 1 is a block diagram of a system for providing IP multimedia information of a subscriber in a general voice call connection.

1, an inbound and outbound exchange that communicates with a Home Location Register (HLR / IMSR) 70 storing subscriber information via a No.7 network 80 based on a Signaling Transfer Protocol (STP). MSC / VLR) 20a, 20b; A multimedia page providing device (Phone Page Server) (PPS) 60, a packet incoming control system (Traffic Control), which is a media providing device through an IP (Intelligent Peripheral) network based on a Session Initiation Protocol (SIP). Message storage and handling system (MSS) 40a, 40b communicating with Subsystem (TCS) 50 is connected with MS 10a, 10b, respectively.

At this time, the short message server (SMSC) 30 is connected to the NO.7 network 80 and the IP network 90, and the MSS 40a, 40b includes a packet subscriber database and a SIP server.
No. 7 is the seventh signaling system defined by CCITT (International Telegraph and Telephone Advisory Committee) as one of the common signal lines.
The common line signal refers to a control signal exchanged between the exchange and the exchange, and the common line signaling method refers to a method of exchanging control signals between the exchanges.
In other words, the common line signaling method is a method of connecting switching devices between high speed data links and transmitting signals required for control of a plurality of call lines through data links.
CCITT (International Telegraph and Telephone Advisory Committee) has internationally standardized the above common line signaling system.
The control signal of the exchange period transmitted and received by the above No. 7 signal system is called a No. 7 signal (i.e., an exchange period control signal), and an exchange which transmits and receives a No. 7 signal is called a No. 7 exchange.
Therefore, the network connected to the exchange period No.7 and transmitting control signals is referred to as a network No.7.
