The present invention relates to a method of operating a connected call service in conjunction with an intelligent network, and in more detail, an incoming call is made to a phone number specified by a calling party, and an intelligent network performing interworking and control according to a request to a calling user by interworking an intelligent network. It relates to a connection call service operation method that interoperates with.

Call forwarding service, which is one of the existing mobile service providers, is well known.

The incoming call service is set up at the called party. For example, an office worker working at a fixed location may connect a mobile phone including a cell phone, a PDA, and a personal digital assistant (PDA). When you can not answer the phone over the landline, the incoming call is a service to make a call to the mobile terminal. In general, call forwarding is performed during a call or after a predetermined time, a call connection is made to the next telephone number set by the called user.

On the other hand, the group call service, which is one of the voice services of the mobile communication company, is a service that allows simultaneous call with a large number of people in a designated group by attempting a call connection with a specially designated special number.

This group call service is focused on the corporate service concept, that is, business use, and has been applied to various fields through the activation of the Internet and mobile communication services. For example, by establishing a language learning community, language education, which was conducted only in academy, can be used to learn languages through a mobile communication network regardless of time and place.

However, the call forwarding service can prevent inconvenience that the calling user must retry key input and call connection of another phone number when a call is not made to the phone number first inputted for the call attempt. However, the above-mentioned call forwarding has a disadvantage in that a call is made to a phone number specified by a called user, so that the caller does not consider the caller's position paying the call charge. In other words, the telephone number specified by the called user is a service that does not consider the caller's position because the call charge varies according to the region and communication means. In addition, the call forwarding service does not merely perform a change to a call to which a call is made, but various services for notifying additional services, that is, a message related to a call connection, are insufficient.

On the other hand, the group call service, despite the advantage of forming a multi-party call path to call a number of called users, the calling user remembers a feature code for the call transfer and There was a hassle to enter. As a result, there was a limit to making natural calls during calls.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, in which a call forwarding number is registered by a calling party user so that a call forwarding can be made to a phone number designated by the calling party in consideration of a caller's position paying call charges. This is done by interworking with the intelligent network to perform the call connection according to the request and the requesting user to increase the convenience of the user, and to link the intelligent network to deliver the short message or multimedia message related to the call connection to the called party user. The present invention provides a method for operating a connected call service in which an intelligent network is interworked.

One aspect for achieving the above object of the present invention,

a. Registering and managing parameters and additional service information including the connection call telephone number designated by the calling user in the intelligent network and the home location register;

b. Setting, in the home location register, next designated phone number information when a call connection with the telephone number attempted by the calling user is not established; And

c. Performing a call transfer to the phone number set for call resetting

It relates to a method of operating a connection call service interworking with an intelligent network comprising a.

In addition, the intelligent network 23 is provided with an Internet service through a Parlay G / W 235 connected to the SCP 231.

A method of operating a connected call service incorporating the intelligent network of the present invention using the system configured as described above will be described.

In the present embodiment, call connection between mobile stations will be described. Of course, it is well known that the present invention can selectively make a call connection between a mobile station, a general telephone, and a data communication terminal, and is included in a method of operating a call connection between mobile stations described below.

2 is a flowchart illustrating a method of operating a connected call service in which an intelligent network is interworked as a first embodiment of the present invention. As shown in FIG. 2, in order to use the call forwarding service of the present invention, a service request related to call forwarding should be performed to a mobile communication company, and this service request uses a web server 27 using a normal data communication terminal. Or a subscriber, i.e., a caller-related service, by using a swap server 29 using the mobile station 11, or by accessing the intelligent network 23 through a normal personal computer (PC) connected to the Internet. The request is performed (S1, S1 ').

Data related to the call forwarding inputted through various routes are notified to the SCP 231 of the intelligent network 23 (S2), whereby the intelligent network 23 SCP 231 is sent to the home location register 21. In addition to storing the information parameters and additional service information of the side user (S3) and forwarded to the home location register (21) (S4) to store and manage it (S5).

Thereafter, when the calling mobile station attempts to call by inputting an arbitrary phone number, the calling exchange requests the routing information for requesting the location of the corresponding subscriber's phone number from the calling exchange to the home location register 21 (S6). Then, the home location register 21 transmits a routing information request signal to the called side exchange (S7), and the called side exchange transfers the routing information roamed by the called mobile station to the home location register 21 (S8). ). Thereafter, the home location register 21 returns the routing information to the calling side exchange (S9).

Accordingly, the voice call path between the calling mobile station and the called mobile station is allocated.

At this time, if there is no response from the called mobile station (e.g., when the call visibility has elapsed), that is, no call is made, the called exchange sends a call reset request message to the calling exchange. The calling exchange then transmits to the home location register the telephone number to try to connect. On the other hand, the destination exchange performs a response to the call reset request message and releases the assigned voice call path. The call is then set up with a new destination exchange. This process is a conventional process of the existing call forwarding, the present invention can proceed the process related to such call reset, in the present embodiment to omit the process of the request and response of the above call reset request message is made. In order to request a call reset directly from the destination exchange to the intelligent network 23 (S10). The intelligent network 23 instructs the call reset to the home location register 21 (S11), the home location register 21 received the call reset request message is received by the other call reset phone number stored or forwarded itself Reset it.

Here, the telephone numbers to be called at the call resetting is made in the order of telephone numbers input by the user. And, regardless of the phone number designated by the calling user, the call is made in the rotation order with respect to the phone number input after the phone number to be called when the call is reset.

On the other hand, the home location register 21 selects the telephone number designated as the next number (S12), and transmits the routing information request signal of the corresponding telephone number to the called party exchange (S13). The called party exchange transfers the routing information roaming by the newly designated called party mobile station to the home location register 21 (S14). Thereafter, the home location register 21 returns the routing information to the calling side exchange (S15). Accordingly, the voice call path between the calling mobile station and the called mobile station is allocated. At this time, if there is no response from the called mobile station, i.e., no call is made, the called exchange requests the network 23 to reset the call (S16). Of course, the normal call resetting request message request and response may be made as in step S10 described above. The intelligent network 23 instructs the call reset to the home location register 21 (S17), the home location register 21 received the call reset request message is received by another call reset phone number stored or transferred itself Reset the call (S18).

The above process is performed for one cycle (Cycle) by the number of phone numbers designated by the calling party subscriber, and when the call resetting of all the phone numbers is made (S19). On the other hand, when a call is made with the called mobile station in the call resetting process, a call path is formed with the calling exchange and the called exchange period (S19).

Meanwhile, the above-described first embodiment describes a process of resetting a call according to a phone number sequentially input by a calling user during a call resetting process. As shown in FIG. Depending on the message indication, a call resetting to any telephone number can optionally be made.

3 is a flowchart illustrating a method of operating a connected call service in which an intelligent network is interworked as a second embodiment of the present invention. As shown in Fig. 3, the process proceeds from step S1 to step S10 of the first embodiment, and stores a parameter for selecting a call reset telephone number in the called mobile station in the intelligent network 23 and the home location register 21; And manage it.

Then, when there is a call reset request, the intelligent network 23 transmits a response voice message to select the call reset telephone number to the calling exchange (S31). The voice message is transmitted to the calling mobile station (S32), and when the telephone number information selected from the calling mobile station is input to the calling exchange (S33), the calling exchange sends the selected phone number to the home location register 21 and the intelligent network. It is delivered to 23 (S34). The intelligent network 23 performs a call reset instruction to the home location register 21 (S35), the home location register 21 received the call reset request message is a call reset to the telephone number selected by the calling mobile station. Will be done. Subsequently, the same processes as those in steps S13 to S16 of the first embodiment are performed (S36 to S39). Thereafter, the above steps S31 to S39 are repeatedly performed, and when a call connection is made in the call viewing process, a call path is formed between the calling exchange and the called party exchange period (S40).

Meanwhile, in the case of the first embodiment and the second embodiment, only the process of resetting the call path is described, but in the present invention, the additional service related to the call forwarding may be performed. That is, the supplementary service is to deliver a short message and a multimedia message to the called mobile station.

4 is a flowchart illustrating a method of operating a connected call service using an additional service according to a third embodiment of the present invention. As shown in Fig. 4, when the process of step S1 to step S10 of the first embodiment (or step S1 to step S10 of the second embodiment) is performed, and there is a call reset request, the first embodiment described above. Alternatively, the call resetting process as in the second embodiment will be performed.

At this time, in the third embodiment, the intelligent network 23 transmits a voice message regarding whether to proceed with call resetting to the calling exchange for resetting a call (S51). Step S51 described above may optionally be performed. In other words, regardless of the control in the intelligent network, it is possible to proceed immediately to respond to the request of the calling mobile station. Such immediate response may be possible by entering a predetermined specific number or code.

At this time, in the case where it is desired to use the supplementary service in the calling mobile station without proceeding with the call resetting process as in the first and second embodiments described above (S52), the supplementary service request message delivered from the calling mobile station. To transmit from the source exchange to the intelligent network (23) (S53). In response, the intelligent network 23 requests the corresponding additional service to the short message service center 25 or the multimedia service center 25 (S54). The short message service center 25 or the multimedia service center 25 requests the delivery of the message to the home location register 21 (S55). In this way, the home location register 21 sequentially transmits the corresponding message to all of the designated phone numbers to the called side exchange (S56). The called mobile station receives the message.

The present invention is not limited to the above-described embodiments, and it will be apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.

As described above, in the method of operating a connected call service interworking with the intelligent network according to the present invention, since the calling user can select a forwarding phone number, the forwarding phone number can be designated in consideration of call charges, etc. By transmitting short and multimedia messages to both designated call forwarding telephone numbers, integrated control for each designated telephone number group can be achieved.
