Abstract

The present invention relates to a method for displaying caller information in which a call waiting service subscriber can collect and display caller information from an originating exchange and an SCP regardless of existing basic call processing when a call waiting service subscriber requests a call occupancy in an active network. In the related art, in order to collect and display caller information in a destination exchange, a separate detection point must be additionally implemented in an additional service control process, which has a disadvantage in that interference between implementations and processing procedures are complicated. As the basic call progresses and the caller information collection and display functions are processed in the same process, the subscriber information data may be inconsistent or the existing basic call control may be disturbed due to time delay.

Therefore, the present invention generates a separate caller information collection process irrelevant to the supplementary service control process to collect and display caller information, thereby eliminating the need to additionally implement a separate detection point in the supplementary service control process. Through the detection point, caller information can be collected and displayed, and the interference and influence that can be generated with the basic call processing can be eliminated, and the problem caused by interworking with supplementary services can be eliminated.

Description

Calling Identity Delivery Method

The present invention relates to a method for displaying caller information. In particular, when an incoming call request is received while a call waiting service subscriber, which is an incoming supplementary service, is busy, the caller information is obtained from the calling exchange and the SCP regardless of the existing basic call processing. The present invention relates to a method of displaying caller information that can be collected and displayed.

In the past, a large amount of hardware and software had to be changed in order to add new functions or introduce new services to the exchange, which required a lot of time and cost. In order to implement this in general-purpose hardware and software, the next-generation intelligent network (hereinafter referred to as the 'intelligent network') is designed to greatly reduce the time and cost of designing and implementing a new service at the exchange and to provide the service more efficiently. In addition, by building the intelligent network in a general-purpose hardware and software environment, it is possible to quickly introduce the latest technology in accordance with the rapidly developing computer technology to facilitate the performance improvement of the exchange.

In such an intelligent network environment, the exchange can provide various additional services such as automatic call generation, call distribution, call transfer, call in case of busy / no answer, call blocking, call waiting, etc. Among them, call waiting service Is a service for notifying that another caller is requesting a call connection to his / her own phone number in a busy state, which means that the called exchange displays the information of another caller to the busy subscriber.

In this case, the function of displaying the caller information by the called exchange corresponds to an additional service. To this end, the caller information should be collected and displayed from the corresponding calling exchange, and the caller information collection and display function is performed by the additional service control process. Batch processing.

In more detail, in order to display caller information for a call waiting service subscriber in a conventional intelligent network, as shown in FIG. 1, the basic call control processes 11A and 11B of the originating exchange and the called party may be used. The basic call control process 21 and the supplementary service control process 22 of the exchange and the service control system (Service Control Point; hereinafter referred to as 'SCP', 31) has a structure interoperating with each other, and display the corresponding caller information The function is handled by the supplementary service control process 22 of the destination exchange.

That is, when the called side exchange receives the incoming call occupancy request for the subscriber who is currently busy in the basic call control process 21, the called exchange switches to the additional service control process 22 to provide call waiting service. The supplementary service control process 22 performs caller information collection and display function to display caller information to the called party.

First, the process of transitioning to the supplementary service control process 22 when the incoming call occupancy request for the busy subscriber is described, which means that the calling subscriber is the basic call control process 21 of the called exchange through the basic call control process 11A. After the interworking with the called party, the second calling party requests the incoming call occupied by the called party currently in the call to the basic call control process 21 of the called party exchange through the basic call control process 11B. Then, the basic call control process 21 of the called party exchange checks whether the called party is registered in the call waiting service.

At this time, when the called subscriber is identified as the subscriber registered in the call waiting service, the corresponding basic call control process 21 generates the additional service control process 22 having the same process ID (IDentifier) as itself.

Subsequently, the existing basic call control process 21 is terminated to provide the corresponding call waiting service, and the newly created supplementary service control process 22 receives the control right under the same process ID (stop_start). After receiving the own information of the process 21, the corresponding call waiting supplementary service processing is started.

In this state, when the additional service control process 22 collects and displays caller information to process the call waiting supplementary service, the newly created supplementary service control process 22 may be located. Request and collect the calling party's telephone number by the basic call control process (11B) of the calling exchange, and then collect and send the calling party's name and additional information to SCP (31), the service layer of the intelligent network, using the collected calling telephone number. do.

Then, the additional service control process 22 displays the collected caller information, that is, the calling party's telephone number, name, and additional information on the terminal of the called subscriber, and then transitions to the existing additional service processing routine to proceed with the additional service. do.

As described above, in the conventional intelligent network, in order to collect and display caller information (telephone number, name and additional information) at the destination exchange, the additional service control process 22 provides a detection point for performing the above intelligent network processing. Because of the additional implementation, there is a disadvantage in that interference between the additional services and the implementation procedure are complicated.

In addition, as the existing basic call progresses and the caller information collection and display function is processed in the same process, the subscriber information data may be inconsistent or a delay may occur in the existing basic call control due to a time delay. When (21) is terminated and the additional service control process 22 transfers the control right under the same process ID, there is a problem that a software error occurs when the own information of the basic call control process 21 is lost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to generate and process a separate caller information gathering process irrelevant to the supplementary service control process to display a caller information that is an incoming supplementary service. Therefore, it is possible to collect the caller information and display it to the called subscriber through the detection point for basic call processing, without having to additionally implement a detection point for processing the caller information display-related intelligent network in the additional service control process.

Another object of the present invention is to collect and display caller information through a separate process irrelevant to the basic call control process or the supplementary service control process, thereby eliminating interference or influence that may occur with the basic call processing, and providing supplementary services. It is to eliminate the problems caused by interworking with.

A feature of the present invention for achieving the above object is the process of checking whether the called subscriber is a registered subscriber to the call waiting service when the incoming call occupancy request to the incoming call subscriber; Creating a caller information collection process to collect caller information in order to display caller information when the called subscriber is registered in the call waiting service; In the caller information collection process provides a caller information display method comprising the step of collecting the caller information in conjunction with the source exchanger and the SCP where the second caller is located and displaying the information on the terminal of the called subscriber through the basic call control process have.

Here, the process of collecting the caller information is characterized in that in the basic call control process to generate the caller information collection process, which is a basic call control process having a different process ID from the self to collect the caller information.

The collecting and displaying of the caller information may include: requesting and collecting a caller's telephone number from a calling party exchange in which a second calling subscriber is located in a newly generated caller information collecting process; Requesting and collecting the caller name and additional information from the SCP, which is a service layer of the intelligent network, using the collected caller phone number; And transmitting the calling party information collected from the calling side exchange and the SCP to a basic call control process and displaying the same on the terminal of the called subscriber.

Further, the requesting and collecting the caller name and the additional information to the SCP may include: a caller name from the SCP using a detection point corresponding to a point in time when an incoming call request is received from an originating exchange among the existing basic call processing related detection points. And collecting additional information.

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

In the intelligent network according to the present invention, a structure for displaying caller information for a call waiting subscriber is shown in FIG. 2, which is a basic call control process (11A, 11B) of a calling exchange and a basic call of a called exchange. The control process 21, the additional service control process 22, and the caller information collection process 23 and SCP 31, which is the service layer of the intelligent network, have a structure interoperating with each other, and caller information for displaying the caller information. The collection function is processed in the caller information collection process 23 generated by the basic call control process 21 of the destination exchange.

At this time, the caller information collection process 23 is a process generated by the basic call control process 21 to collect caller information when the incoming call occupancy request for the subscriber on the current call, it is irrelevant to the basic call control process 21 After collecting the corresponding caller information in association with the basic call control process 11B and SCP 31 of the calling exchange, it is transmitted to the basic call control process 21 and displayed on the terminal of the called subscriber.

That is, in the present invention, in the linkage between the caller information display and the existing additional service, the caller information display is performed by collecting caller information in association with the intelligent network in the caller information collection process 23 irrelevant to the basic call control process 21. By minimizing the impact on existing basic calls due to the function, it is possible to eliminate the possibility of failure and error of basic call control.

On the other hand, in the intelligent network having the above-described structure with reference to Figure 3 attached to the caller information display procedure according to the present invention will be described in detail as follows.

First, a specific originating subscriber interworks with the basic call control process 21 of the called exchange through the basic call control process 11A, and then the second originating subscriber makes a basic call control process 11B while talking to the called party. If the incoming call is requested to the called party that is currently busy by the basic call control process 21 of the called party exchange (step S31), the basic call control process 21 of the called party exchange is performed by the called party. It is checked whether or not it is registered in the call waiting service (step S32).

At this time, when the called subscriber is identified as a subscriber registered in the call waiting service, the corresponding basic call control process 21 is a basic call control process having a different process ID (IDentifier) from itself in order to display the calling party information to the called subscriber. After generating the calling party information collecting process 23 (step S33) to collect the calling party information from the calling side exchange, the user continues to perform basic call processing for the called party currently busy.

Accordingly, the newly generated caller information collection process 23 requests and collects the caller's telephone number to the basic call control process 11B of the calling exchange in which the second calling subscriber is located (step S34), and then collects the called telephones. Caller information is requested and collected by SCP (31), which is the service layer of the intelligent network, by using the number. At this time, the caller information collection process (23) occupies the incoming call from the originating exchange among existing detection points for collecting caller information. Using the detection point 23 (Term.Attempt) corresponding to the time when the request is received, the sender name and additional information, which is the caller information, are collected from the SCP 31 (step S35).

Then, when the caller information collection process 23 passes the collected caller information, that is, the caller's telephone number, name, and additional information to the first basic call control process 21 (step S36), the corresponding basic call control process ( 21) displays the calling party's telephone number, name, and additional information, which are received caller information, on the terminal of the called subscriber (step S37).

Then, after generating the additional service control process 22 capable of processing the call waiting service having the same process ID as itself, the basic call control process 21 terminates to provide the corresponding call waiting service, and newly The generated additional service control process 22 transfers the control right to the same process ID and performs call waiting additional service processing (step S38).

As described above, in the intelligent network according to the present invention, in order to display the caller information for the call waiting service subscriber, the caller information collection process 23, which is a separate basic call control process instead of the additional service control process 22, is generated and processed. Thus, the caller information may be collected by using a detection point for basic call processing without displaying an additional detection point for processing the caller information display-related intelligent network in the additional service control process 22, and then may be displayed to the called subscriber. Will be.

In addition, the embodiment according to the present invention is not limited to the above-described embodiments, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.

As described above, the present invention by generating and processing a separate caller information collection process irrelevant to the additional service control process to perform the display function of the caller information that is the incoming supplementary service, the caller information display-related intelligent network in the additional service control process It is possible to collect the caller information and display it to the called subscriber through the detection point for the basic call processing without having to implement the additional detection point for processing.

In addition, the present invention collects and displays the caller information through a separate process irrelevant to the basic call control process or the additional service control process, thereby eliminating interference or influence that may occur with the basic call processing and adding the same. Interoperability with the service can be eliminated.
