Description

Method and providing advertisement using ring back tone service and apparatus therefor}

The present invention relates to a ring back tone service, and more particularly, to a method and apparatus for providing an advertisement using a ring back tone service.

The ring back tone service is a service that allows the caller to hear the melody or other sound effects of the caller (receiver) or the caller's own choice, instead of the monotonous mechanical sound of the `` toe-toe '' that the caller (sender) has normally heard. Say.

In the existing communication network, when a calling subscriber attempts to make a call, a predetermined constant ring back tone is provided. In the existing call ring tone, the same call ring tone is not known to determine whether the corresponding call attempt is properly made, and it is not possible to provide personalized and personalized service to the subscriber. In addition, even in the case of providing a personalized service according to the subscriber could only hear a predetermined melody or sound effects.

Advertisement service using the ring back tone means to play an advertisement instead of the melody or other sound effects heard in the ring back tone service. By the way, by the existing method can be told only a predetermined advertisement. In order to effectively advertise, the subscriber who listens to the advertisement must meet the conditions of the advertisement. Therefore, a method of providing the advertisement to only the subscribers that meets the specific conditions determined by the advertiser is needed.

The technical problem to be achieved by the present invention is to provide a method and apparatus that can select and provide a suitable advertisement for each subscriber by using the ring back tone service.

Another object of the present invention is to provide a computer-readable recording medium having recorded thereon a program for executing an advertisement providing method using the ring back tone service on a computer.

According to an aspect of the present invention, there is provided a method for providing an advertisement using a ring back tone service, the method comprising: (a) receiving a ring back tone request from an exchange; (b) comparing the information of the subscriber who requested the call with a predetermined advertisement constraint to determine whether the subscriber corresponds to the advertisement constraint; (c) if the subscriber meets the advertisement constraints, transmitting an advertisement sound source associated with the advertisement constraints to the exchange; And (d) if the subscriber does not meet the advertising constraints, forwarding a predetermined basic ring back tone to the exchange.

Advertisement providing apparatus using a ring back tone service according to the present invention for achieving the technical problem, the sound source sending unit for transmitting the ring back tone requested from the switch; A sound source for comparing the information on the subscriber who requested the call with a predetermined advertisement constraint to select a corresponding ring tone sound source according to whether the subscriber corresponds to the advertisement constraints, and delivering the selected ring tone sound source to the sound source transmitter. A selection unit; A subscriber management unit managing information on a subscriber and transferring information on a subscriber who has requested the call to the sound source selection unit; And a sound source manager for managing a sound source of the call connection sound and transferring the selected call connection sound source to the sound source selection unit.

In the device, the advertisement constraint and subscriber information is preferably stored in a predetermined bitmap structure.

The sound source selection unit performs a logical AND operation on each of the subscriber information and the advertisement constraint represented by the bitmap for each bit, and determines that the subscriber corresponds to the advertisement constraint when the result is the same as the subscriber information. Comparator; A sound source determining unit selecting an advertisement associated with the advertisement constraint as a ring tone sound source when the subscriber corresponds to the advertisement constraint, and selecting a predetermined basic ring back tone when the subscriber does not correspond to the advertisement constraint; And a sound source transmission unit for receiving the selected call connection sound source from the sound source manager and delivering the sound to the sound source transmitter.

The present invention provides a method and apparatus for allowing an advertisement to be displayed only to subscribers who satisfy certain conditions in order to enhance an advertisement effect in an advertisement service using a ring back tone.

Advertisement service using the ring back tone refers to a service that listens to advertisements instead of the melody or other sound effects heard in the ring back tone service.

The present invention provides a method of using a bitmap to increase the effect of the advertising service using the ring back tone. In order to reflect the advertiser's requirements in the advertising service, a method for expressing the advertiser's constraints and a method for selecting a subscriber corresponding to the advertisement condition are required. In the present invention, the constraints of the advertiser are expressed using a bitmap, and the subscriber's information is expressed and stored as a bitmap using a method of expressing the constraints of the advertiser. The bitmap storing the subscriber's information in the actual service is compared with the bitmap of the constraints specified by the advertiser, and the corresponding advertisement sound source is selected and provided when the subscriber corresponds to the constraint specified by the advertiser.

Hereinafter, a method and apparatus for providing an advertisement using a ring back tone service according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an embodiment of an advertisement providing apparatus using a ring back tone service according to the present invention.

Referring to FIG. 1, the advertisement providing apparatus using the ring back tone service according to the present invention includes a sound source transmission device 50, a sound source selection device 60, a subscriber management device 70, and a sound source management device 80. It is desirable to. For convenience of explanation, the calling subscriber 10, the called subscriber 20, the calling exchange 30, and the called exchange 40 are shown together in FIG.

The subscriber receiving the service in the communication network can be largely divided into the calling subscriber 10 and the called subscriber 20. Outgoing subscriber 10 is the person making the call, and incoming subscriber 20 is the person answering the call. The calling party 10 and the called party 20 may be located in the same communication network or in different communication networks.

The ring back tone is also called a call waiting tone or a ringing tone, and refers to a tone sent to the calling party 10 to notify the calling party 10 that a calling signal is being sent to the called party 20.

The originating exchange 30 is a device that processes outgoing calls to the originating subscriber 10 and provides a ring back tone to the originating subscriber 10.

The destination exchange 40 is a device that processes the incoming call to the called party 20.

When the sound source transmitting device 50 receives the call connection sound to be transmitted from the calling exchanger 30 to the calling subscriber 10, the sound source transmitting device 50 requests the sound source selection device 60 to select a sound source, and the call connection sound selected by the sound source selection device 60. It passes to the outgoing exchange (30).

The sound source selection device 60 is a device that receives a request from the sound source transmitting device 50 and selects a sound source. The type of the call connection sound to be heard to the calling subscriber 30 is selected. For this purpose, the subscriber management device 70 receives subscriber information and the sound source management device 80 receives information about the sound source.

The subscriber management apparatus 70 is a device for managing subscriber information and is responsible for subscribing, deleting, and changing a service.

The sound source management device 80 is a device for managing sound sources, and provides a sound source to the sound source selection device 60 and changes it.

As shown in FIG. 1, the calling subscriber 10 is connected to the calling exchange 30, the calling exchange 30 is connected to the called exchange 40, and the calling exchange 30 is connected to the sound source transmitting device 50. The sound source transmitting device 50 is connected to the sound source selecting device 60. The subscriber management apparatus 70 and the sound source management apparatus 80 are connected to the sound source selection apparatus 60.

2 is a signal flow diagram illustrating each step of a method for providing an advertisement using a ring back tone service according to the present invention.

Looking at the advertisement providing procedure using the ring back tone service with reference to FIG. 2, first, when the calling subscriber 10 forwards a call request with the called subscriber 20 to the calling exchanger 30 (S1), the calling exchanger 30 transmits an incoming request for the called party 20 to the called exchange 40 (S2). In this process, there may be interworking with an exchange transmitting a signal, for example, a relay exchange.

The originating exchange 30 requests the sound source transmitting device 50 to send out the tone waiting sound for all origins, that is, whether or not the originating subscriber 10 registers the ring back tone service (S3). The sound source transmission device 50 requests a sound source number from the sound source selection device 60 in order to know the type of the call connection sound to be transmitted (S4).

The sound source selection device 60 selects the most suitable advertisement sound source number for the corresponding calling party 10 using the called number and the information of the calling party 10 and transmits the selected sound source number to the sound source sending device 50 (S5). The sound source transmitting device 50 transmits a call waiting sound (advertisement) corresponding to the received sound source number to the calling exchange 30 (S6), and the call waiting sound is transmitted to the calling party 10.

When the called party 20 makes a call in response to the call (S7), the calling exchange 30 requests the call release to the sound transmitting device 50 and the sound transmitting device 50 stops transmitting the ringback tone (S8). ).

3 is a flowchart illustrating each step of a method of selecting an advertisement sound source number in a sound source selection apparatus.

The sound source transmitting device 50 requests the sound source selecting device 60 to select a sound source number to be heard by the calling subscriber 10 (S100).

The sound source selection device 60 analyzes the called number in order to confirm whether or not the calling subscriber 10 is registered in the RBT service (S200).

As a result of analysis of the called number, when the calling party 10 registers with the RBT service, a sound source selection algorithm is performed (S210 and S220). The sound source selection algorithm determines the sound source number of the call waiting sound to be sent to the calling subscriber in consideration of the called number, the calling number, and the call time. In the present invention, the advertisement constraints specified by the advertiser and the information of the subscriber are represented and stored in a bitmap structure, and compared with each other, the advertisement sound is transmitted when the subscriber corresponds to the advertisement constraint. If the advertisement does not meet the constraints, the basic ring back tone is transmitted.

If the calling party 10 does not register the ring back tone service as a result of the analysis of the called number, the default ring back tone sound source is selected (S210 and S230).

The sound source selecting device 60 transmits the selected sound source number to the sound source transmitting device 50 (S240).

4A to 4C are diagrams illustrating an embodiment of an advertisement constraint bitmap used in an advertisement providing method using a ring back tone service according to the present invention.

Hereinafter, a method of comparing an advertisement constraint and a subscriber condition using a bitmap will be described using the case of FIGS. 4A to 4C as an example.

The main technical details of bitmap advertising services are how to construct a bitmap, how to store advertiser's advertising constraints and subscriber's information using a bitmap, and how to select an advertising sound source using a stored bitmap.

To illustrate this method, it is assumed that there are six conditions, such as gender, age, occupation, marital status, parental status, and vehicle ownership, as shown in FIG.

In this embodiment, it is assumed that each condition can have 10 ranges. For example, ages 0-12, 13-15, 16-18, 19-22, 23-25, 26-29, 30-34, 35- 39 years old, 40-50 years old, and 50 years old or older. The profession specifies ten kinds of guitars, businessmen, office workers, civil servants, investors, housewives, students, agricultural and fisheries, foreigners, and diplomats.

At this time, less than 10 ranges in each condition designate reserved bits. In the case of gender, there are two ranges, male and female, so the remaining eight ranges use reserved bits. In the case of marital status, the presence of children, and vehicle ownership, the eight ranges besides the two ranges, the reservation bit is used.

The number of advertisement conditions and the number of ranges in each condition are specified as six and ten in this embodiment, but this is merely exemplary and there is no limitation.

In order to store the advertisement constraints and the subscriber's information, the ranges for each condition are sequentially numbered as shown in FIG. 4A. When numbering, the reservation bit is also included. One bit is allocated to each range when the bitmap is stored.

To store the ad constraints as a bitmap, set the range you want to specify in each condition to 1 and the range you do not want to specify in the condition to 0. Reserved bits, that is, bits corresponding to an undefined range, are all set to one. After configuring the advertisement constraints as a bitmap, the bitmap is stored in a table for managing advertisement information. In the real service, the advertisement constraint bitmap is loaded into memory to improve performance.

Figure 4b shows the configuration of the bitmap when the advertising constraints of the advertiser is male, age 20 to 39 years old, regardless of occupation, married married, child is child, vehicle is inclusion.

In order to store the subscriber information as a bitmap, the range corresponding to the subscriber information under each condition is defined as 1, and the remaining range that does not match the subscriber information is set to 0. The reserved bits are all set to zero. The subscriber information bitmap thus set is stored in a table for managing subscriber information.

Figure 4c shows a bitmap of the subscriber's information when one subscriber is male, age is 24, occupation is student, marriage is unmarried, child is absent, and vehicle is attracted.

Advertising sound source determination method according to the present invention comprises the following steps.

First, a bitmap storing subscriber information is extracted from the subscriber table. The bitmap of the extracted subscriber information is compared with the bitmap of the advertisement constraints stored in the memory. In this case, if the logical AND operation is performed for each bit and the result matches the subscriber information bitmap extracted from the subscriber table, the corresponding advertisement sound sources are transmitted to the calling exchange to transmit the advertisement sound to the calling subscriber.

If the result of the logical product is different from the subscriber information bitmap, the subscriber does not meet the advertisement constraints specified by the advertiser, and thus the basic ring back tone is sent.

As described above, according to the method and apparatus for providing an advertisement using a ring back tone service according to the present invention, in the advertisement service using a ring back tone, an advertisement constraint of an advertiser can be expressed simply and efficiently, and an advertisement sound source suitable for information of a subscriber is provided. You can make quick choices to increase system performance.

First, using the present invention can be expressed simply and efficiently advertising constraints of the advertiser. The advertiser only needs to select a portion of the range of advertisements that he wants to advertise, so the advertisement constraints can be easily expressed.

Second, since the information of the subscriber is also displayed in the bitmap, selecting the advertisement sound source that matches the information of the subscriber in the actual service can be performed by simply taking a logical AND of the bitmap information and the advertisement constraints of the subscriber. In this way, the process of selecting the advertisement sound source can be processed simply and quickly, and also sufficient functions can be performed. In addition, the overall performance of the system can be improved by quickly processing the advertisement sound source selection process, which is a main function of the advertisement service.

The present invention can be embodied as code that can be read by a computer (including all devices having an information processing function) in a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

According to the method and apparatus for providing an advertisement using a ring back tone service according to the present invention, the advertisement constraints and the information on the subscriber are expressed in a bitmap structure, thereby easily and efficiently expressing the advertisement constraints of the advertiser. You can increase the system performance by quickly selecting the right sound source.
