At this time, the service switching system SSP in the wireless intelligent network WIN coupled to the calling exchange recognizes the intelligent network service call in the call connection request signal received at the calling exchange (step 403). Here, the recognition of the intelligent network service call refers to recognizing the "function information providing service for the called terminal" set corresponding to the calling terminal identifier.

The SSP forwards the information about the intelligent network service call previously recognized to the SCP (step 405). SCP forwards the service information to the service provisioning server to perform the service corresponding to the intelligent network service call information (step 407). Here, the service providing server is a separate device coupled to the SCP or includes a software system mounted in the SCP.

The service providing server, which has received the service information, requests model information of the called terminal from the subscriber DB based on the identification information of the called terminal obtained from the SCP (step 409). The subscriber DB reads the model information of the called terminal from the database according to a request of the service providing server (step 411). The subscriber DB transmits the read device type information to the service providing server (step 413).

The service providing server requests the function information according to the model of the called terminal to the function information DB by the terminal model based on the type information on the called terminal obtained from the subscriber DB (step 415).

Referring to Fig. 5, the originating terminal transmits a call connection request signal to the originating exchange (step 501). Here, the call connection request signal includes a calling terminal identifier corresponding to the calling terminal and a called terminal identifier corresponding to the called terminal. Upon receiving the call connection request signal from the originating terminal, the originating exchange recognizes the intelligent network service call through the intelligent network service call recognition function (step 503). The originating exchange exchanges the service information including the intelligent network service call information to the service providing server (step 505).

Next, the service providing server requests model information of the called terminal from the subscriber DB based on the identification information of the called terminal included in the service information (step 507). The subscriber DB reads the model information of the called terminal from the previously stored subscriber information database (step 509). The subscriber DB transfers the read device type information to the service providing server (step 511).

The service providing server that receives the type information from the subscriber DB requests the function information corresponding to the type information of the called terminal to the function information DB for each terminal type based on the type information of the called terminal (step 513). The terminal device function information DB reads the corresponding function information from the previously stored device function information and transmits the function information to the service providing server (steps 515 and 517). The service providing server provides the calling terminal with function information of the called terminal (step 519). At this time, the service providing server transmits the corresponding function information to the calling terminal by voice or text message through a short message center (SMC), an ARS system or an intelligent peripheral device (IP) (step 521). Of course, even in this case, similar to the above-described example, the function information is transmitted to the calling terminal by voice transmission or text message transmission before the call is set up between the calling terminal and the called terminal, or after being set as a call between the calling terminal and the called terminal. It is delivered by text message transmission method.

In the above process, the service providing server may perform data transmission and reception with the subscriber DB and the function information DB for each terminal model through the calling exchange. In addition, the service providing server may be mounted on a separate home exchange or a called side exchange coupled with the originating exchange. Detailed description of such a case will be omitted since it will be apparent to those skilled in the art through what is described herein.

Also, in the above process, the calling side exchange may obtain service setting information for the intelligent network service call from a separate device such as a home location register (HLR) equipped with a subscriber DB.

At this time, the call connection request signal includes a calling terminal identifier corresponding to the calling terminal and a called terminal identifier corresponding to the called terminal. The calling side exchange requests the called location information for the call connection request signal to the home location register (HLR) (step 603).

The HLR requests routing information to at least one destination exchange for a called location information request received from the originating exchange (step 605). The HLR then receives a response signal for routing information from the particular destination exchange (step 607). As a separate procedure, the HLR determines whether to register a service for the calling terminal based on the calling terminal identifier (step 609). If it is determined that the originating terminal is a service registered terminal, the HLR transmits location information on the called exchange and service setting information on the calling terminal to the calling exchange (step 613). In addition, if necessary, the HLR may transmit routing information about the service providing server to the calling exchange. If the originating terminal is not a service registered terminal, the HLR transmits only the location information of the called exchange to the originating exchange (step 611).
