Ring back tone service method for IP private branch exchange networks}

The present invention relates to a method for providing a ring back tone in an IP private exchange network consisting of an IP protocol exchange branch (Internet Protocol Private Branch eXchange) and a plurality of IP telephones and a coloring server. Is connected to a connected LAN, and when receiving a call from an IP private exchange, the coloring server calls the coloring server at the same time so that the coloring server sends out a preset ring tone so that it is effective through general equipment such as a general personal computer. The ring back tone service was enabled.

With the development of information and communication technology and the expansion of user base, various additional services have been developed and provided to satisfy various tastes of communication consumers as well as call quality such as sound quality and stability. Ring tone service.

The ring back tone service is to transmit and reproduce a predetermined sound source without transmitting a uniform ring back tone when the exchange calls the called terminal at the request of the calling terminal. Provided by telecommunications operators operating exchanges on PSTN, Public Switched Telephone Network (PSTN), and private ring networks where internal networks such as corporations and organizations are established are sent by the coloring server connected to the private exchange.

FIG. 1 illustrates a system configuration when such a ring back tone service is provided in an IP private exchange network including an IP private exchange 100 and a receiving terminal 109 which is a plurality of IP phones connected through a LAN. As can be seen through the drawing, the coloring server 200 is directly connected to the IP private exchange 100 is configured.

The present invention has been made in view of the above-described problems, and connected to the public communication network 300 and connected to a plurality of destination terminals 109 and a LAN (LAN) and the private LAN exchanger 100, Coloring server 200 is connected to the database 210, which contains the ring tone sound source information is connected, the lake new step (S11) and the IP private exchange that the call signal is received from the public communication network 300 to the IP private exchange 100 After the 100 extracts the identification information of the called terminal 109 from the call signal, the calling terminal 109 calls the coloring server 200 and at the same time calling the coloring server 200 and the coloring server 200 the database. (210) to retrieve the call connection sound source information and transmits it to the IP private exchange 100 (S21), and the IP private exchange 100 is temporarily stored in the buffer unit 132 the received sound source information Temporary storage step (S22) and, When the IP private exchange 100 reproduces the sound source information and transmits it to the public communication network 300 (S23) and the receiving terminal 109 responds, the IP private exchange 100 stops transmitting the sound source and the public communication network Call connection sound service method in the IP private exchange network, characterized in that consisting of a connection step (S30) for establishing a communication path between the 300 and the called terminal 109.

Through the present invention, an effective call connection service is possible without directly connecting an expensive server configured with a dedicated communication interface with an IP private exchange, and a user can be easily accessed and set up by directly connecting a coloring server to a LAN.

As a result, it is possible to easily and economically establish a system for providing a ring back tone of the IP private exchange network, and to obtain user convenience of the system.

The detailed configuration and implementation of the present invention will be described with reference to the accompanying drawings.

First, Figure 2 is a system configuration of the present invention, the system for carrying out the present invention is a plurality of IP connected to the public exchange network 300, the IP private exchange 100 and connected via a LAN (LAN) It consists of a receiving terminal 109, which is an IP phone, and a coloring server 200 connected to the LAN.

The coloring server 200 is connected to a database 210 that contains sound source information, and the sound source information may be set differently for each called terminal 109.

The IP private exchange 100 controls the flow of calls between the public telecommunications network 300 and the IP-based private switching network, and performs conversion between a time division multiplexing (TDM) signal and an IP packet.

3 is a block diagram of an embodiment of the IP private exchange 100 applied to the present invention. As can be seen from the same figure, the IP private exchange 100 is connected to a public communication network 300 to receive a voice signal. A LAN interface 150 such as a LAN card that transmits and receives an IP packet connected to a communication unit 140 for transmitting and receiving LAN, a central processing unit 110 for controlling all components, and a CPU 110. A memory unit 131 connected to the CPU 110 and performing a conversion between the IP packet and the TDM signal under the control of the CPU 110, and a storage device 131 that stores various programs and protocols necessary for the operation of the IP private exchange 100. ) And a buffer unit 132 for temporarily storing the sound source information transmitted from the coloring server 200.

Figure 4 shows the process of the present invention through the IP private exchange network of the above-described configuration, as can be seen through the figure, the service method of the present invention is a public private network 300 from the IP private exchange 100 The new signal is started in a new phase (S11) is received.

The IP private exchange 100 receiving the call signal extracts the called terminal 109 identification information from the call signal and then calls the corresponding called terminal 109 and simultaneously calls the coloring server 200 connected to the LAN. Call step (S12).

That is, by calling the coloring server 200 connected to the LAN as one called terminal 109, it is processed in a manner that calls the coloring server 200 unconditionally when calling each incoming terminal 109, the coloring server ( In response to the call of the IP private exchange 100, 200 receives an IP packet including the identification information of the called terminal 109.

The coloring server 200 receiving the identification information of the called terminal 109 retrieves the call connection sound source information set in the corresponding called terminal 109 by querying the database 210 and transmits it to the IP private exchange 100. The transmission step S21 is performed.

The database 210 connected to the coloring server 200 contains sound source information used as a call connection sound, and different sound source information may be stored for each called terminal 109. The department and rank of the called terminal 109 user Alternatively, various sound source information may be set depending on whether or not to be occupied.

In the illustrated embodiment, the coloring server 200 and the database 210 are represented as being separated, but the coloring server 200 and the database 210 are not necessarily physically separated and stored in the coloring server 200. The database 210 may be built into the device 131.

Since the coloring server 200 of the present invention is connected through a LAN unlike the prior art connected to the IP private exchange 100 through a separate line, the user connects to the LAN using his computer, and then the sound source described above. Setting of information can be performed relatively freely and easily.

In addition, since the identification information of the called terminal 109 is transmitted to the coloring server 200 when each called terminal 109 is called, it is also possible to manage the call log through a method such as recording it in the database 210.

Receiving the sound source information from the coloring server 200 IP private exchange 100 performs a temporary storage step (S22) for temporarily storing the sound source information in the buffer unit 132, and immediately reproduces the sound source to public communication network ( A sending step (S23) for sending to 300 is performed.

Thereafter, when the called terminal 109 responds, the IP private exchange 100 stops transmitting the sound and performs a connection step (S30) for establishing a communication path between the public communication network 300 and the called terminal 109. Will be done.

Through the present invention as described above, an effective call ring tone service is possible without directly connecting an expensive server configured with a dedicated communication interface with the IP private exchange 100, and a user's ease by directly connecting the coloring server 200 to a LAN.
