It is connected with a gatekeeper, an Internet phone terminal, and a general telephone, which stores detailed information and manages a reception mode state, and checks the reception mode of the reception side set in the gatekeeper before the communication connection is made in response to a call request. It characterized in that it comprises a gateway for connecting the communication in the mode.

In accordance with another aspect of the present invention, there is provided a method for controlling a reception mode of a communication system according to the present invention. The method for controlling an Internet phone / general phone reception mode includes: (a) a reception mode of a user terminal registered with a gatekeeper; (B) determining whether a call request signal from a transmitting side requesting access to a user terminal registered with the gatekeeper is transmitted to the gateway; and (c) as a result of the determination of step (b). When the call request signal of the transmitting side requesting connection to the user terminal is transmitted, checking the registered receiving mode of the receiving user terminal to connect to the gatekeeper in the corresponding receiving mode; It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, the reception mode control apparatus of the communication system according to the present invention includes the Internet phone terminal A 101, the general phone A 102, the gateway A 103, the Internet phone terminal B 104, and the general. The telephone B 105, the gateway B 106, and the gatekeeper 107 are provided.

Here, the Internet phone terminal A 101, the general telephone A 102, and the gateway A 103 constitute one local network (network A) by H.323, and the Internet phone terminal B 104, the general telephone. B105 and gateway B106 form another local network (network B) by H.323.

The Internet phone terminals A and B (101, 104) are personal computers that can receive the Internet service, and receive the Internet service by the following software.

In order to receive Internet service, you must be an Internet member by accessing an Internet Service Provider (ISP) using a Point-to-Point Protocol (PPP), a modem and software for accessing the Internet. . After registering with the Internet terminal in this manner, the Internet service can be used through the World Wide Web (WWW) browser. Then, the software for the Internet phone can be used to make voice calls over the Internet with other users on the Internet using the same software.

In addition, it is possible to connect to the general telephones A and B 102 and 105 of the public switched telephone network (PSTN) through the gateways A and B (103 and 106).

The gatekeeper 107 registers detailed information about terminals, and in particular, stores information about reception modes between terminals, and manages reception mode states between terminals in real time. The communication protocol used between each Internet phone terminal and the gatekeeper 107 transmits information on the reception mode of the Internet phone terminal using the Registration Admission Status (RAS) protocol of the H.323 standard. That is, the reception mode is set by being transmitted as nonstandard data in the Terminal Info field of the RRQ (Registration) message for registering the terminal.

The gateways A, B (103, 106) serve to connect the receiver's Internet phone or a regular telephone in accordance with the reception mode set in the gatekeeper 107 in response to a call request from the sender side. That is, the reception mode check is confirmed by the nonstandard data value of the destination terminal info field of the LRQ / LCF (Location) message.

In addition, the reception mode is set by transmitting non-standard data in the Terminal Info field of the RRQ (Registration) message for registering the terminal.

In step 202, it is determined whether a call request signal is transmitted to the gateway. For example, when the telephone B is dialed to the network B using the Internet phone terminal A 101 or the general telephone B 102 of the network A, the gateway A 103 dials the telephone number to the gateway B 106 via the Internet. Sends a signal requesting a connection to the corresponding receiver.

In step 203, when the information regarding the telephone number requesting the call to the gateway B 106 is received in step 202, the reception mode set in the gatekeeper 107 is checked before the call path is connected. Confirm with the nonstandard data value of the destination terminal info field of the LRQ / LCF (Location) message.

In step 204, a call path is connected to the reception mode identified in step 203. That is, when the confirmed reception mode is the Internet phone mode, the gateway B 106 connects the call path to the Internet phone terminal B 104 to enable a call to the Internet phone. And, if the confirmed reception mode is the normal telephone mode, the gateway B 106 connects the call path to the ordinary telephone B 105 to enable a call to the ordinary telephone.

Of course, in the case of making a call from Network B to Network A, the reception mode set in the gatekeeper 107 is checked in the same manner to access the Internet phone through the Internet phone terminal A 101, or the general phone A. (102).
