Call Processing Method for Opinion Poll Service in Intelligent Network

The present invention relates to a call processing method for a poll service in an intelligent network, and in particular, it is possible to automatically poll all subscribers in a designated group without advertising the telephone number of a service subscriber. A call processing method for a poll service.

In general, an intelligent network is a service network that processes, provides, and manages various new services quickly and easily. The intelligent network is composed of transport network layer, signaling network layer, and service network layer, and service network layer is composed of service control point and service management system. Service Management System), the signaling network hierarchy is composed of a signaling relay point (Signalling Transfer Point), the transmission network hierarchy is composed of a service switching point (Service Switching Point).

Services provided through the intelligent network configured as described above include free phone service, credit call service, premium rate service, teleconferencing service, and virtual private network. Service (Private Virtual Network Service), Personal Number Service, Televoting Service, Emergency Number Service, Voice Mail Service, Electronic Mail Service Service, Call Me Card Service, etc. are provided.

In particular, the telephone poll service assigns one or several numbers to service subscribers, and then allows the service user to attempt a call to select a specific number advertised in advance. It is a service that informs the subscribers of the results, and is used for collecting opinions on major issues related to the effects of new advertisements, administration, and conducting voting before the election.

The call processing process in the intelligent network for the telephone poll service will be described based on the schematic intelligent network structure shown in FIG. 1.

That is, information about a plurality of numbers (pre-advertised numbers) assigned to service subscribers who want to have a telephone poll is kept in a service control system (hereinafter referred to as SCP) 102, and the subscriber station 108 When a given service user attempts to make a call, the subscriber station 108 is connected to a service switching point (hereinafter referred to as SSP) 104 via a local exchange 106. Digit information sent from is transmitted.

The SSP 104 analyzes the authorized digit information and transmits the authorized digit information to the SCP 102 when the attempted call is a call for using an intelligent network. Accordingly, the SCP 102 analyzes the authorized digit information to identify the corresponding service subscriber, and provides the SSP 104 with information (such as the DN of the IP) about the intelligent network service assigned to the identified service subscriber. . The SSP 104 uses the information about the authorized service to send a local broadcast 106 to the local exchange 106 for the announcement message of the information provided in the intelligent information providing system (Intelligence Peripheral). It provides a path to be provided to the corresponding subscriber station 108 through.

The digit information input from the subscriber station 108 according to the announcement message received through the provided path is transmitted to the SCP 102 through the SSP 104 and collected to obtain statistical results for a certain period of time. The disconnection to the subscriber is made by the hook on of the subscriber terminal 108.

As described above, the call processing for the existing polling service should be advertised so that subscribers who are subject to the poll can know the telephone number previously assigned to the service subscriber because the polling target is only available as the calling subscriber. In addition, since the subscriber must wait for a certain period of time at the receiving party level, it is difficult to poll in the desired time for the desired number of subscribers. For example, if you want to poll 100 people, you should wait no matter how long it takes to collect 100 subscribers.

An object of the present invention is to provide a call processing method for a poll service that can be polled without advertising (non-advertising) a telephone number of a service subscriber. have.

Another object of the present invention is to provide a call processing method for a poll service that can obtain poll results within a desired time for a desired number of subscriber groups.

In order to achieve the above object, the method according to the present invention comprises a service control system consisting of service control logic and subscriber data, a service exchanger interconnecting the intelligent networks, an intelligent information providing system, and a local connection between the service exchanger and the subscriber terminal. An intelligent network configured and operated by an exchange, the intelligent network comprising: inputting at least one subscriber number of a predetermined service subscriber who wishes to poll in a service control system, and then requesting to start a poll by the service control system; Requesting an incoming call by sending one of the subscriber numbers entered in the service control system to the service switcher according to a polling start request; when an incoming response is received through the first outgoing line occupied by the incoming request, Notifying the incoming response; After receiving the call response notification step, if the information on the corresponding intelligent information providing system is received from the service control system, performing connection with the corresponding intelligent information providing system; providing the corresponding intelligent information by occupying the second outgoing line; Establishing a bearer channel between the first outgoing line and the second outgoing line through a space splitting switch provided in the service exchange when the connection with the system is made; Transmitting and storing the predetermined digit information received from the subscriber station to the service control system through the intelligent information providing system according to the guide information provided from the intelligent information providing system through the established bearer channel; connection to the incoming subscriber terminal Repeating the steps of: repeating the incoming call request step to the canceling step for all subscribers input by a predetermined service subscriber; And obtaining statistical results of the polls by using the information stored in the storing step.

1 is a schematic diagram of an intelligent network structure, which is a computer control system composed of service control logic and subscriber data (Service Control Point, hereinafter referred to as SCP) 102, and a service exchanger serving as a gateway for interconnecting an intelligent network and an intelligent network. (Service Switching Point, hereinafter abbreviated as SSP) 104, Local Exchange (abbreviated as LE) 106 serving to interconnect the service user's subscriber station 108 and the SSP 104, and It consists of an intelligent information providing system (Intelligence Peripheral, hereinafter referred to as IP) 110 that provides a variety of intelligent information that can be provided in the intelligent network.

FIG. 2 is a schematic functional block diagram of the SSP 104 for performing a call processing method for a poll service according to the present invention, and the called party information for the subscriber terminal 108 which wants to poll from the SCP 102 Is applied, the polling call processing control unit 202 for controlling the polling call processing according to the present invention, the first relay line matching processing unit 204 for performing relay line matching processing for connection with the LE 106, and IP 110. And a second relay line matching processing unit 206 and a space division switch (Space SW) 208 for performing relay line matching processing for connection with the control unit.

3 is a flowchart illustrating the operation of the SSP 104 in the call processing method for the poll service in the intelligent network according to the present invention.

Referring to the operation of the embodiment according to the present invention configured as described above are as follows.

First, the service subscriber enters the telephone number of a particular subject (sometimes treated as a specific group) who wishes to poll in SCP 102, and then requests a poll. The telephone numbers are sequentially transmitted to the SSP 104 one by one. At this time, when the polling results are sequentially transmitted to SCP 102, the polling result of any subject is collected in SCP 102, and at the same time as the request for disconnection of the subscriber, the telephone number of the subject corresponding to the next order is SSP 104. Is made by way of transmission.

The telephone number authorized to the SSP 104 is transmitted to the poll call processing control unit 202 as a specific called number. The poll call processing control unit 202 proceeds from step 301 to step 303 when one specific called number is applied, translates the number of the called number, and then sends the first relay line matching processor 204 to the corresponding subscriber. Requires a connection. The first relay line matching processing unit 204 configured to accommodate an integrated digital network (hereinafter, referred to as ISDN) or an R2 relay line performs outgoing occupancy processing when a subscriber connection request is received, and then outgoing occupancy. The notification is sent to the poll call processing control unit 202.

In step 305, the call processing controller 202 receiving the outgoing call occupancy notification proceeds to step 307 to request a switching delay between the outgoing relay line occupied by the first relay line matching processor 204 and the space division switch 208. . Accordingly, the first relay line matching processing unit 204 proceeds with the call for connection with the subscriber without waiting for the connection notification from the space split switch 208. That is, when the LE 106 requests a connection to the subscriber station 108, the LE 106 provides a ring to the subscriber station 108, so that the subscriber station 108 hooks off. If so, the LE 106 notifies the first relay line matching processing unit 204 of the incoming response to the subscriber.

The poll call processing control unit 202 proceeds from step 309 to step 311 when the response signal to the corresponding subscriber is received, and notifies the SCP 102 of an incoming response. Accordingly, SCP 102 sends the DN of IP 110 related to the poll to SSP 104. After receiving the DN of the IP 110 in step 313, the SSP 104 proceeds to step 315 to request an IP connection to the second relay line matching processing unit 206 accommodating the IP 110. After receiving the IP connection request, the second relay line matching processing unit 206 occupies the relay line for the IP 110 connection, and then notifies the poll call processing control unit 202 of the outgoing relay occupation.

The poll call processing control unit 202 which has received the outgoing call occupancy notification in step 317 proceeds to step 319 to request the switching delay of the space splitting switch to the second tiered line matching processing unit 206. Accordingly, the second relay line matching processing unit 206 performs the connection process with the IP 110 without waiting for the switching connection notification to the space split switch 208. That is, the second relay line matching processing unit 206 requests the connection through the outgoing relay line occupied by the IP 110, and when a response according to the connection request is received from the IP 110, to the poll call processing control unit 202. The IP response and the ID of the second relay line matching processing unit 206 to which the IP is connected are sent.

The poll call processing control unit 202 proceeds to step 323 when the IP response and the ID for the second relay line matching processor 206 are received from the second relay line matching processor 206 in step 321. The IPs occupied by the subscriber timeslot occupied by the first relay line matching processing unit 204 and the second relay line matching processing unit 206 while providing an ID for the second relay line matching processing unit 206 to the processing unit 204 ( The connection between timeslots of 110 is required.

Accordingly, the first relay line matching processing unit 204 connects the outgoing line (time slot) and the second relay line matching processing unit 206 to the subscriber occupied by the first relay line matching processing unit 204 through the space splitting switch 208. The switching of the space splitting switch 208 is controlled to be connected between the occupied outgoing line through. When switching is performed, a bearer channel (B) between the subscriber station 108, the LE 106, the first relay line matching processor 204, the space splitting switch 208, the second relay line matching processor 206, and the IP 110 is transmitted. Bearer CH, or voice channel) is formed, IP 110 transmits the corresponding announcement to the subscriber station (108). The broadcast announcement is, for example, "Enter 1 if you agree, enter 2 if you disagree".

When the digit information is input from the subscriber station 108 according to the guide broadcast provided as described above, the digit information is transmitted from the IP 110 through the space division switch 208. IP 110 sends the authorized digit information directly to SCP 102. SCP 102 stores the information received from IP 110 for statistical processing and requests SSP 104 to disconnect the subscriber.

When the connection release command is received in step 325, the SSP 104 proceeds to step 327 and requests the first relay line matching processing unit 204 to disconnect the corresponding subscriber and then returns to step 301 to return the SCP 102. ), And wait for the called party to be transmitted to the next sequence.

SCP 102 performs statistical processing on the digit information received from IP 110 in the same manner as before, and informs the service subscriber of the result of all the polls completed or when requested by the service subscriber.

As described above, the present invention provides a call processing method capable of sequentially polling by a specified number of subscribers who want a poll as a called subscriber, thereby advertizing the telephone number assigned to the service subscriber in advance. It is possible to do polls without having to do it, and it is also possible to automatically poll in the desired time for the number of subscribers and subscribers in the desired region.
