In this case, a service identifier (Feature Code) for requesting the provision of the customer information provision service may be input. Here, it is preferable to use letters and numbers such as '*' or '#' as a service identifier, and use them in the form of '# 100', '100 *', '# 100 *', etc. (S202).

When a call request signal including a service identifier is input, the calling exchange 130 checks the telephone number of the calling terminal, the telephone number of the called terminal, and the service identifier included in the call request signal, and checks the identified service identifier by the HLR 140. In step S204).

The HLR 140 confirms that there is a request for providing the customer information providing service through the received service identifier, and sends a service request number (SRN: Service Request Number, SRS) to the customer information providing service server 150 for the customer information providing service. Hereafter referred to as 'SRN') (S206), and transmits the confirmed SRN to the originating exchange 130 (S208).

The originating exchange 130 checks the customer information providing service server 150 through the received SRN, and then transmits a message requesting access (S210).

The customer information providing service server 150 receiving the access request message from the originating exchange 130 transmits a connection response message for approving the connection to the originating exchange 130 (S212), and the originating exchange 130 is the called terminal. Requests to provide the subscriber subscriber information with the phone number of (S214).

The customer information providing service server 150 uses the received telephone number of the called terminal to receive the name, telephone number, alias, picture, emoticon, address, landline phone number, E-mail address, family relationship, Search for information such as a hobby (S216), and transmits the retrieved called subscriber information to the calling terminal 110 through the calling exchange 130.

At this time, the called party information transmitted to the calling terminal 110 is transmitted through a video call formed between the calling terminal 110 and the calling exchange 130, the called party information is in the form of image, image or text. It may be transmitted (S218).

The calling terminal 110 displays the received called subscriber information. At this time, instead of the ring tone indicating that the call request is in progress to the called terminal 180 or the ring back tone set by the called party in advance, the received called party information may be displayed, and at the same time as the ring tone or the ring back tone The called subscriber information may be set to be displayed (S220).

When the called party information is normally received, the calling terminal 110 generates a called subscriber information reception response message that responds to the normal reception of the called party information, and transmits the received subscriber information to the calling exchange 130 (S222).

The originating exchange 130 that has received the called subscriber information reception response message from the originating terminal 110 transmits a call connection request message for a video call to the called terminal 180 through the terminating exchange 160 (S224).

After transmitting the call connection request message to the destination terminal 180, the destination exchange 160 checks whether a call connection response message including the authorization information for the video call is received from the destination terminal 180 (S226). .

When the call exchange response message is received from the called terminal 180, the destination exchange 160 transmits a call connection response message indicating that the video call is acknowledged to the calling terminal 110 through the calling exchange 130 (S228). ), A session for a video call is set up between the calling terminal 110 and the called terminal 180 receiving the call connection response message, thereby making a video call (S230).

Here, in step S226, the destination exchange 160, if the call connection response message from the destination terminal 180 is not received during the preset response waiting time, a message indicating that there is no response from the destination terminal 180 After generating and transmitting to the calling terminal 110, the call connection procedure is terminated.

In operation S226, when a call connection response message including video call rejection information is received from the called terminal 180, the caller terminal 180 generates a message indicating that the video call is rejected, and thus, the calling terminal 110. After the transmission, the call connection procedure ends.

Here, when the video call between the calling terminal 110 and the called terminal 180 is started or the call connection procedure ends, the calling terminal 110 may stop displaying the called subscriber information. Alternatively, the receiving subscriber information may be continuously displayed on a part of the screen of the calling terminal 110 until the video call ends.

In addition, in the method for providing subscriber subscriber information according to an embodiment of the present invention, without providing and confirming a service identifier for the customer information providing service, the customer information providing service is provided by checking whether the calling subscriber subscribes to the customer information providing service. It can also be implemented to provide. In this case, step S202 in which the user of the calling terminal 110 inputs a service identifier for the customer information providing service and step S204 in which the calling exchange 130 transmits the service identifier to the HLR 140 may be omitted.

The calling party requests the video call by inputting only the called number, and the calling terminal 110 transmits the calling number and the called number to the calling exchange 130. The calling exchange 130 receiving the calling number and the called number checks whether the calling subscriber subscribes to the customer information providing service through the HLR 140, and if the calling subscriber is confirmed to be a subscriber of the customer information providing service, the customer information providing service. Checking the SRN of may be performed after step S206 to provide to the originating exchange 130.
