In the present invention, instead of a ringback tone that a caller hears when making a call in a wired or wireless communication network, a caller selects a receiver instead of a tone generator and connects to a stored database system (server) instead of a tone generator. It provides a method and apparatus for listening to the caller to a different sound specified by the. As a result, the present invention differs from the conventional technology of playing a uniform ringback tone and the technology of playing a different ringback tone (signal tone) according to the selection of the calling subscriber (Power-off, Busy, No). Answer, Paging No Response) can solve the problem, and even before the answer to the recipient can determine whether there is a wrong call, and provide a new service that meets the personality and purpose of the called user.

Description

METHOD AND APPARATUS FOR GENERATING TERMINATIONER SELECTED SUBSTITUTES OF RINGBACK TONES IN WIRED, WIRELESS TELECOMMUNICATION NETWORK}

The present invention relates to a method and apparatus for allowing a caller to hear a caller with a different sound selected by a called subscriber in a call exchange system that actually provides a ringback tone that is heard when making a call in a wired or wireless communication network.

Currently, when a caller attempts a phone call in a communication network such as a general telephone network or a mobile communication network, an exchange controlling a called subscriber adopts a method of uniformly giving ringback tone to the caller according to the ITU-T standard. In other words, when a caller makes a call to a called party in a communication network, a tone of a certain interruption period and frequency designated by the ITU-T standard is heard.

Figure 1 is a simplified representation of the exchange system of the TST (Time-Space-Time) Switching structure to explain the position where the ringback tone is heard when the call originated according to the prior art (a) is the same exchange system (B) is where the call is made and the call is made from another exchange system of the same operator, and (c) is the case where the call is made and the call is made by another operator. . Accordingly, looking at the position at which the ring back tone according to the prior art is heard, FIG. 1 (a) shows a case where an originating and receiving party is made in the same exchange system in an exchange system having a time-space-time (TST) switching structure. First, in case of regular call origination, the calling subscriber opens the fixed calling party and the switching path in the Call Control Block immediately when the call is made and is provided by the tone generator of the called subscriber matching. The tone is delivered to a specific slot of the called subscriber's time switch and is heard by the calling party.Secondly, in the case of a mobile calling party, the called subscriber matching part is not confirmed until the called subscriber responds to paging when the calling subscriber makes a call. After the tone responds to paging, the TST switching path is called because the destination terminal determines which subscriber matching part belongs to. Tone provided by the called party and the called party matching unit is provided to the calling party until the called terminal responds. Fig. 1 (b) is a case where the call and the call are made in another exchange system of the same operator. The same applies to the case where a large number of relay exchange systems are included between the originating and terminating exchange systems, and when a caller completes signal processing after the originating call and the final exchange side and the ACM after the IAM, a specific channel of the relay line T1 or E1 (PCM As a specific time slot is allocated between the originating and the destination exchange system, the Tone at the subscriber matching part of the destination exchange system is transmitted to the originating subscriber. Second, in the case of mobile phones, a number of relay exchange systems are included between originating and receiving exchange systems. The same applies to the case when the caller ends the calling exchange system, the final call exchange system and the signal processing after the IAM until the ACM. Since a specific channel of E1 (specific time slot of PCM) is allocated between originating and final terminating exchange system, ringback tone is delivered from originating exchange to originating party, but until paging response is received at destination relay line matching part until there is response to paging. The ringback tone of the called party matching unit is transmitted. FIG. 1 (c) shows a case where a call originates and a call is received from another operator. When the IAM and ACM are finished during the signal processing between the gateway switch and the gateway operator, the number of relay exchange systems increases until the mobile terminal is located before the location of the mobile terminal. In the relay line matching part of the destination side gateway exchanger, a tone of Progressive Tone is added and after the location is determined, the gateway operator of the destination operator When the IAM and ACM are completed during the final exchange and signal processing, the Tone Generator of the terminating line relay matching part is checked.If the subscriber matching part of the terminating terminal is confirmed by paging success, the ringing back tone is applied to the calling party until the terminal responds. In the prior art, the ringback tone method, which is heard at the time of origination, provides uniformly the same tone in the end-to-end exchange system that controls the called party, and when the existing ringback tone is used, it is heard until the answer of the called party. There is a problem that it is not possible to determine the presence of a wrong connection with the uniform ringback tone. In addition, the ringback tone method according to the prior art is inadequate in providing a service in accordance with the user's personality and purpose.In contrast, in the alternative system, other commercial advertisements are provided in a separate system in the communication network instead of the ringback tone. Or a technique in which the caller hears and receives a call charge benefit until the called subscriber answers by controlling the calling terminal or until the called subscriber answers the ANM message to the calling party, has the following problems. b), a problem that occurs when the call type of (c) is a problem that originating and incoming calls of (b) are made by another exchange system of the same operator. First, when the called party's status is No Answer, Busy, Paging No Response, that is, it does not answer a call, is busy, or is out of service area. According to the prior art, when IAM and ACM are completed during ISUP signal processing between the originating and incoming exchange system, the tone or announcement corresponding to each situation is heard from the terminating exchange system to the calling party. However, there is a problem that there is no method to identify and classify them and send them to the calling subscriber in the protocol implemented in the current network. Second, among the additional services generalized by service providers, the called party is automatically connected or VMS. In case that the connection is made to an additional service such as (Voice Mailing System), according to the prior art, the announcement message corresponding to the situation of the called party corresponding to the first problem after the IAM and ACM is finished during ISUP signal processing in the destination exchange system A third destination exchange with the announcement that it is going to be an additional service and According to the conventional technique, the sender hears the ringback tone heard from the third party exchange system again, and when the called party and the VMS respond, the third party exchange responds with an ANM (Answer) message among the ISUP signaling messages. The system or terminal that delivers to the calling party and judges this message to provide the calling party commercial advertisement knows as the message that the first called party responds and connects with the calling party, but the caller listens to the announcement of other called parties (auto-connected subscriber) and VMS. Third, the caller delivers to the caller various announcements (e.g., runaway, broadcast, etc.) that the caller can hear from the call exchanger and the relay exchange system during call processing from call origination to the call exchange system. The same way of knowing the progress of the call when using the existing ringback tone (signal tone) has not been proposed. The problems of this third party are as follows: First, second, and third problems raised in Fig. 1 (b), and other incoming subscribers are subscribed to Incoming Call Screening (ICS) service. Each mobile phone operator is competitively launching various types of supplementary services. Among them, there is an ICS service defined in IS-771 of TIA / EIA. In case of SKTelecom, there are Call ID, Password Call Acceptance, and DoNotDisturb. Examples include password call acceptance service, caller ID designation service, and call rejection service. To describe the characteristic of the above service with the description of Password Call Acceptance service among each service, if the caller tries to call the called party with this service subscribed to, the called party's gateway system Press the password set by the user '. The caller is the service that proceeds to the next call if it is the same as the password set by the called party in two or three attempts. For each service, the calling exchange system or the called gateway exchange system announces the announcement to the calling party, and the caller performs one or more actions (for example, pressing a specific button) according to each announcement condition. The following call processing procedure will proceed normally only when the subscriber has set up the same situation. However, the normal call processing process of interpreting various announcements provided by the called party at the calling party is not required without declaring how each announcement is interpreted by the commercial advertisement system or the calling terminal and performing appropriate actions. It is virtually impossible to see the wider variety of value-added services offered by wireless carriers.In conclusion, the technology changes the ringback tone by the caller's choice to give different sounds for all kinds of calls from a particular caller. Whether the implementation method is provided by the calling terminal or the method provided by a specific system in the communication network, the purpose of the caller is to select the caller and present the commercial advertisement to the caller in place of the existing ringback tone until the caller responds. In the current network signal processing process, There is no choice but to rely on the ISUP ANM message (if the ISUP signal processing) given by the new exchange. Before the ANM message, the call flow processing method that proceeds according to the various conditions of the incoming and relay exchange system described above is solved. Otherwise, in the current wired / wireless communication network, the technology proposed by the above inventions may be limited or impossible to implement. The ringback tone heard during transmission from the wired / wireless communication network is not a time waiting for the caller insignificantly. In the incoming and the relay exchange system, the caller plays the role of a voice information channel that tells the caller the status of the call until the caller responds to the caller.The artificial control of the caller is to accurately control the caller's connection status with the caller. Waste of resources due to various incomplete calls on communication network for network operators Users would result in loss of time and economic biyongreul.

Accordingly, a first object of the present invention is to provide a method and apparatus for listening to a different sound selected according to the taste of a called subscriber by the control of the destination exchange in place of a uniform ringback tone according to the conventional communication network technology. However, even when receiving a call connection request from the subscriber of the wireless carrier, the replacement sound of the ringback tone set by the called subscriber is actually transmitted to the calling party until the called party responds (while the existing ringback tone goes out).

The present invention, in a general telephone network, a mobile communication network or a new type of communication network in the future, replaces the ringback tone that has been uniformly heard according to the ITU-T specification in a call exchange system that conventionally controls a called subscriber regardless of the receiver's intention. As a method of selecting and recording according to the taste of the called subscriber and listening to the caller, as described in the related art, the existing ring until the called party answers the tone provided by the called exchange system controlling the called subscriber in the existing communication network. The caller hears during the same time that the backtone is out

Compared to the conventional technology, the present invention provides a variety of sounds selected by the called party at the stage in which the existing ringback tone is heard in the final destination exchange system when the subscriber of the unspecified domestic and international wired / wireless communication network attempts to receive the subscriber of the specific network operator. As described above, the above-mentioned problems are solved and the calling terminal selected by the calling terminal and the communication network using the specific system described in the prior art selects the subscriber to listen to the advertisement and then receives the caller's call rate benefit or the subscriber sends the text along with the advertisement. The technical gist differs from that of calling a call-back number, listening to an advertisement for a predetermined time, and then making a free call for a predetermined period of time.

The present invention is compatible with a call scenario that listens to the ringback tone according to the prior art, the technology for generating a replacement sound of the ringback tone and the existing ringback tone by the present invention can operate in a specific communication network at the same time, the ring A call processing scenario that can be heard as a substitute for backtones is provided based on the North American mobile network standard, IS-41C, and is based on IS-41C, and is based on the US Telecommunication Industry Association (TIA) / Electronic Industry Association (EIA). The function of each service node of a call processing process defined in WIN (Wireless Intelligent Network) of TR-45.2 will be described in detail with reference to FIGS. 3 and 4 to replace interworking in a relatively simple general telephone network. .

2 is a diagram illustrating a signal processing flow in a communication network according to the prior art. Referring to Fig. 2, when the originating exchange system sends an initial address message (IAM) to the destination exchange (step S100), the destination exchange system transmits an address completion message (ACM) (step S110). From the step, the receiver terminal rings and the caller hears the ringback tone until a response message (ANM) is transmitted (step S120).

3 is a view showing a ringback tone replacement sound generating method according to a preferred embodiment of the present invention. The subscriber profile / database has a specific supplementary service field (eg, substitute tone service field), and in the case of a substitute tone, it is set to a specific value. As a preferred embodiment of the present invention, the conventional ringback tone may be set to H'0000, and in the case of a substitute sound, to H'FFFF.

The mobile switching center (MSC) 400 determines and determines a specific additional service field, and requests an information analysis request (step S1500) requesting a specific service to the SCP (service control point: 500).

The process from step S1000 to step S1400 in Fig. 2 is the same call processing process as the mobile telephone call of the prior art. That is, in step S1000, the originating exchange MSC / VLR 200 requests LocReq (Location Request) from the HLR (Home Location Register) 300.

Subsequently, in step S1100, the home location register (HLR) 300 requests a routing number request for inquiring to connect the destination terminal to the destination MSC / VLR (Mobile Switching Center / Visitor Location Register) 400.

As a result, the destination exchange MSC / VLR 400 provides the HLR 300 with information about the Temporary Local Directory Number (TLDN), which is an identification symbol temporarily assigned to the destination terminal to identify the destination terminal during call setup. In the rotreq forwarding step, in step S1300 the HLR 300 transmits a location query response (locreq) to the originating MSC / VLR (200). As a result, when the called party is powered off or busy, the announcement or tone is heard by the calling party at the calling exchange. In other cases, an ISUP call to which an IAM is transmitted is attempted. (S1400)

On the other hand, in step S1400 it is determined whether the ringback tone tone or the substitute tone according to the setting value of the specific supplementary service field of the called party (e.g., substitute tone service field) stored in the database of the called party exchange, and if the substitute tone, any substitute It is not specified where to read the tone and give the replacement sound to the calling party.

Accordingly, the service control point (SCP) 500 receives the analyzed information defined in the wireless intelligent network (WIN) from the MSC 200 in step S1500.

Here, the interpretation information includes information such as a mobile phone number, that is, a mobile identification number (MIN) and a specific additional service field, and whether the service is registered for a substitute sound service and which IP is stored in the substitute sound. In other words, it means information about which route to find the IP.

Subsequently, in step S1600, a seize resource operation (SeizeRe) is requested to an IP (Intelligent Peripheral (IP) 600), and the TLDN (temporary local directory number) received in step S1600 is transmitted to the MSC.

Here, the resource occupancy request is a step of querying a temporary local directory number (TLDN) for recognizing IP 600 for obtaining a substitute tone.

In addition, when disconnection resource is received from the MSC, resource release may be requested to IP 600. Meanwhile, in step S1500 described in FIG. 2, when it is set as a substitute sound, analysis information may be requested to a service control point (SCP), and a result may be awaited.

In addition, in step S1600, after confirming whether the subscriber is registered in the SCP database and the corresponding IP number, seize resource to obtain a TLDN (temporary local directory number) for routing to the corresponding IP 600. ).

In step S1700, the IP 600 receiving the SeizeRes (Seize Resource) returns a TLDN that can be routed to the IP in the result. In addition, the SCP 500 carries the TLDN to the MSC 400 in step S1800 to respond to the analyzed information.

As a result, in step S1900, the MSC 400 performs a call attempt with the returned TLDN. Subsequently, in step S2000, the IP 600 invokes an InstReq (InstReq) instruction request to the SCP 500 to query the received MIN for which replacement sound the SCP 500 receives.

Here, the instruction request is a command to specify which of the alternate sound of the assigned IP to select.

As a result, the SCP 500 queries the database for the type of substitute sound of the MIN in step S2100 and outputs the result as an SRFDir (specialized resource function directive) to the IP 600. Subsequently, the IP 600 receiving the SRFDir finds the substitute tone, connects to the incoming call, and transmits the substitute tone to the caller. (Step S2200).

In step S2300 and step S2400, if the terminal responds after paging / alerting to the terminating terminal, it sends DisconnRes to release the relay line between the IP and the terminating MSC to the SCP 500, and sends the originating MSC. Toward (200), the sender and the called party enter the call state after sending ANSUP (Answer Message) of ISUP. If paging fails (No Paging) or if the called party has no answer (No Answer), it sends a DisconnRes to the SCP (500) to release the relay line between the IP and the destination MSC, and the recipient MSC releases the relay line and sends it to the calling party. After giving the appropriate announcement, terminate the call or proceed to the next situation according to the recipient's additional service status.

3 is a diagram showing an embodiment of the operation between the destination exchange and the service control point in the method of generating a substitute sound of the present invention. Referring to FIG. 3, the destination exchange MSC / VLR 400 may transmit the interpretation information ANLYZD [BILLID, DGSTDIAL, TRIGTYPE] to the service control point 500 in step S1500. Here, BILLID of the analysis information parameter may mean charging information, DGTSDIAL may mean an incoming MIN, and TRIGTYPE may mean a substitute sound service.

4 is a view showing an embodiment of the operation between the service control point 500 and IP (Intelligent Peripheral) 600 in the method of generating a substitute sound of the present invention. Referring to FIG. 4, in step S1800, the SCP 500 checks whether the substitute sound of the MIN carried in the DGTSDIAL among the ANLYZD parameters is a subscriber registered in the database, and if the subscriber is a resource for obtaining a TLDN for routing to IP. You can request SeizeResource by IP.

Fig. 5 is a diagram showing an embodiment of the operation between the destination exchange and the service control point in the method of generating substitute sounds of the present invention. Referring to FIG. 5, the service control point 500 loads the TLDN on the destination exchange MSC / VLR 400 in step S1800 and returns interpretation information. Subsequently, the destination exchange 400 may try to find an IP with the TLDN returned in step S1900.

6 is a view showing an embodiment of the operation between the service control point and the IP in the alternative sound generation method of the present invention. Referring to FIG. 6, when a call setup is made in step S1900, in step S2000, the IP 600 requests an instruction number to query the received MIN for the ID number of the replacement sound to the SCP 500. Requires SCP (500).

The SCP 500 searches for a substitute sound ID number of the corresponding MIN in the database in step S2100, and returns the result to the SFDir as an IP. Subsequently, when the IP receiving the SFDir finds the substitute sound and connects it after the ISUP ACM, the caller hears the substitute sound and the destination exchange performs paging and alerting on the called terminal.

The foregoing has outlined rather broadly the features and technical advantages of the present invention to better understand the claims of the invention which will be described later. Additional features and advantages that make up the claims of the present invention will be described below.
