The present invention relates to an apparatus and method for providing a ring back tone for a private exchange, and more particularly, to an apparatus and method for providing a ring back tone for a caller calling a representative number of a private branch exchange subscriber.

The ring back tone (RBT) refers to a ring tone that is heard to inform the caller who is requesting a call connection with the other party, that is, the called party, through the communication network. That is, the ring back tone is used to inform the caller that the call has been received when the exchange has received the telephone number called by the caller. In particular, in recent years, additional services are provided that allow subscribers to set a favorite ring tone for each phone number by allowing them to set a favorite sound source as a ring tone. At this time, the sound source of the ring back tone is stored in a separate server connected to the exchange and is generally provided to the caller according to the request of the exchange.

In general, a communication network for providing a call connection according to a caller's setting to a caller requesting a call connection with the called party is composed of a caller, an originating exchange, a called exchange, a called party, and an IP (Intelligent Peripheral). However, it may be considered that the called party is a subscriber of the private exchange in such a communication network. Such a case will be described with reference to FIG. 1.

1 is a block diagram of a communication network in which a caller calling a caller is a private switch subscriber.

As shown in FIG. 1, a communication network for providing a ring back tone according to a setting of a called party, a private exchange subscriber, to a caller includes a caller 100, a calling side exchange 110, a called side exchange 120, and a librarian. (Private Branch Exchanger; PBX, hereinafter referred to as "PBX") 140, called party 150, and IP (Intelligent Peripheral) 130. In such a communication network, a call connection from the caller 100 to the caller 150 for a call between the caller 100 and the caller 150 is performed as follows. When the originator 100 originates a call calling the called party 150, the originated call is transmitted to the called side exchange 120 through the calling side exchange 110. The receiving side exchange 120 receiving this call checks the state of the called party 150. In this state check process, the called party exchanger 120 provides the caller 100 with a ring back tone according to the setting of the called party 150. When this state check process is completed, the destination side exchange 120 provides the caller 100 with a sound source such as the announcement according to the state of the called party 150. At this time, the sound sources provided to the caller 100 are generally stored in the IP 130. The called party exchanger 120 receives the ring back tone and the announcement according to the setting of the called party 130 from the IP 130 and provides the caller 100 to the caller 100. Here, the IP 130 is a server that stores the sound source of the call connection sound, and may perform functions such as voice guidance, voice recognition, voice recording and storage, text to speech (TTS), and dual tone multi frequency (DTMF) collection. have.

Meanwhile, the PBX subscriber has a general directory number (GDN), which is a representative number, and an IDN (inward dialing number, individual number) subordinate thereto. GDN and IDN are both subscribers. Therefore, even when the GDN or IDN is the called party 150, the called side exchange 120 may provide the caller 100 with a ring back tone according to the setting of each of the GDN or IDN.

That is, since the GDN and the IDN are each separate subscribers, callers are distinguished from each other when the caller 100 attempts to make a call by calling the GDN of the PBX 140 and when the call is attempted by directly calling the IDN. Should be provided. The destination exchange 120 should follow the service characteristics assigned and registered to the GDN when the caller 100 calls the GDN, and if the caller 100 calls the IDN directly and is called with the IDN, The characteristics must be followed.

The called party exchanger 120 provides the caller 100 with a ring back tone corresponding thereto based on the information of the called party 150. In general, the destination exchange 120 and the IP 130 needs information such as a line number (LN) or a called number (DN) of an individual subscriber to provide a ring back tone.

On the other hand, the incoming call to the subscriber of the PBX 140 can be divided into the following three cases.

First, the caller 100 calls the GDN of the PBX 140. Second, the caller 100 directly calls the IDN of the PBX 140. Third, the caller 100 calls the GDN of the PBX 140, but is connected to the IDN of the PBX 140 through a hunting process.

In the case where the destination exchange 120 provides the ring back tone for these three cases, the first two cases are not a problem. In the first two cases, the incoming subscriber itself is the subscriber providing the ring back tone.

However, in the third case, problems may arise. Since the call made by the caller 100 is a GDN, even if the target to be connected to the caller 100 is an IDN, the called side exchange 120 should provide the caller 100 with a ring back tone according to the GDN. That is, when the ring back tone is registered in the GDN, the caller must receive the ring back tone assigned to the GDN. To this end, information of the GDN is required at the time of providing a ring back tone during the incoming procedure for the IDN.

Therefore, in the third case, the destination exchange 120 should include the GDN information in the information for providing the ring back tone. However, in the structure of the current exchange, the IDN side does not know the information of the GDN, and thus, when the incoming call is attempted by the GDN and the call is received by the IDN through the hunting procedure, it is structurally impossible to provide the ring back tone of the GDN.

2 to 4 show such a prior art.

2 is a signal flow diagram according to a process of providing a ring back tone for a call calling a GDN of a PBX according to the prior art.

Figure 3 is a diagram according to the prior art, a signal flow diagram according to the process of providing a ring back tone for a call calling the GDN of the PBX, which is connected to the IDN of the PBX through the hunting process.

FIG. 4 is a flowchart illustrating a ring back tone providing process for a call calling a GDN of a PBX, which is connected to an IDN of a PBX through a hunting process as shown in FIG. 3.

3 and 4, the above-described problem, that is, when the call ring tone according to the setting of the GDN is to be provided to the caller 100, the ring tone according to the setting of the IDN is provided.

Accordingly, an object of the present invention is to provide a ring back tone according to the setting of the GDN to the caller calling the GDN of the PBX, and to provide a ring back tone providing the ring back tone according to the setting of the IDN to the caller calling the IDN of the PBX. Is in.

Another object of the present invention is to provide a method for providing a ring back tone that provides a ring back tone according to the setting of the GDN to a caller who calls the GDN of the PBX, which is connected to the IDN of the PBX through a hunting process.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In the present invention, when the caller 100 calls a caller 150 who is a subscriber of the PBX in the communication network as shown in FIG. 1, the present invention provides a call ring tone according to the setting of the caller 150 to the caller 100. will be. In particular, the caller 100 may call the GDN of the PBX 140, but may not be connected to the GDN, and may be applied to the IDN of the PBX through a hunting process. The present invention is implemented to provide the caller with the ring back tone according to the setting of the GDN in all cases where the caller 100 calls the GDN.

To this end, in the present invention, when a call for calling a representative number (GDN) of a private exchange is received from a communication network, the state of the representative number is determined, and if the representative number is not connectable, the individual number of the private exchange is determined. A number translation unit which performs a hunting process for connecting to the IDN, and outputs an incoming occupancy request signal including information on the representative number information and the individual number obtained in the hunting process, and the incoming call from the number translation unit. A ring back tone for a private exchange comprising: an incoming call processing unit for receiving the occupancy request signal and providing a ring back tone according to the setting of the representative number included in the incoming occupancy request signal to the caller of the call through the communication network; We propose a providing device.

In addition, the present invention, when a call to call the subscriber of the private exchange is received through the communication network, the first process of determining whether the incoming call is a call to call the representative number of the private exchange, and when the incoming call calls the representative number A second process of determining whether the representative number is in an idle state, a third process of performing a hunting process of connecting the incoming call to any idle individual number if the representative number is not in an idle state, and the incoming call; A fourth process including the idle individual number information and the representative number information, and a fifth process of providing a call ringer according to the representative number information included in the incoming call to the caller of the incoming call; We propose a method for providing ring back tone for an exchange.

Such a detailed description of the present invention is as follows.

If the caller 100 calls the GDN of the PBX 140, the called party exchanger 120 calls the ring back tone according to the setting of the GDN even when the IDN dependent on the GDN is determined as the called party 150 through the hunting procedure. Must be provided to (100). To this end, the destination exchange 120 needs the information of the GDN of the PBX when the ring back tone is provided even while the incoming procedure is performed using the IDN of the PBX 140 as the called party 150.

The IP 130 is provided to the caller 100 through the called side exchange 120 according to the setting of the called party 150, based on the information on the called party 150 received from the called side exchange 120. do.

When the caller 100 attempts to call by dialing the PBX 140 GDN, the destination exchange 120 performs PBX 140 call processing prior to the incoming call occupancy. At this time, when the state of the GDN is not possible due to busy (busy), etc., the destination side exchange 120 checks whether there is an IDN dependent on the GDN. If there is an IDN subordinate to the GDN, the destination exchange 120 determines whether there is an idle IDN among the IDNs. If there is an IDN in the idle state, the destination side exchange 120 performs hunting, which is a task for the caller 100 to perform the incoming call request to the corresponding IDN.

At this time, while making a call occupancy request for the IDN, the destination side exchange 120 includes the information of the GDN in the information for the incoming call processing, when the caller needs to provide the caller 100 with the ring back tone according to the setting of the GDN.

When the called party exchanger 120 performs the incoming call request on the corresponding IDN, whether the called side exchange 120 should provide the ring back tone according to the GDN to the caller 100 of the incoming call with reference to the received information, setting of the IDN. Determine whether to provide the ring back tone according to. As a result, when it is determined that the caller 100 needs to provide the ring back tone according to the GDN, the destination exchange 120 requests the IP 130 to provide the information of the GDN and provide the ring back tone accordingly.

This invention will be described below with reference to the drawings.

FIG. 5 is a signal flow diagram illustrating a ring back tone providing process for providing a ring back tone according to the setting of a GDN for an incoming call calling a GDN of a PBX according to the present invention.

As shown in FIG. 5, the destination exchanger 120 may be divided into a number translation unit that performs a hunting process and the like, and a reception processor that connects an incoming call received from the caller 100 through a communication network to the called party 150. Could be. When the number translation unit of FIG. 5 receives an incoming call for calling the GDN of the PBX 140, the number translation unit determines whether the GDN is in a callable state. That is, when the incoming call for calling the GDN of the PBX 140 is received, the number translation unit determines whether the called GDN is idle. As a result of the determination on the GDN, if the GDN is not in a callable state, the number translation unit determines whether there is an idle IDN in step 500, and performs a hunting process to connect the received incoming call to the idle IDN. In step 502, the number translation unit adds the GDN information to the incoming call calling the GDN connected to the idle IDN through the hunting process. That is, after step 502, the incoming call includes both information on the IDN obtained during the hunting process and the first called GDN information.

In step 504, the number translator of the called side exchange 120 outputs an incoming call including the IDN information, which is the object of call connection, and the GDN information, which is a condition for providing the ring back tone, to the incoming processing unit to make an incoming call request. In other words, here, the incoming call including the IDN information and the GDN information is the incoming occupancy request signal. The incoming processing unit of the called side exchange 120 requests the IP 130 to provide the GDN information included in the incoming occupancy request signal received from the number translation unit in step 506 to provide a ring back tone for the incoming call.

The IP 130 provides the caller 100 with the ring back tone according to the setting of the GDN received from the called side exchange 120 in step 508 through the called side exchange 120.

This process will be described below with reference to a flowchart showing the operation of the destination exchange 120 in sequence.

FIG. 6 is a flowchart illustrating a ring back tone providing process for providing a ring back tone according to the set of the representative number for a call to call the main number of a private exchange.

In step 600 of FIG. 6, the destination side exchange 120 receives an incoming call for calling a subscriber of the PBX 140 from the caller 100 through a communication network. In step 602, the destination side exchange 120 determines whether the incoming call received in step 600 is a call for calling the GDN of the PBX 140. If the received call is the call that calls the IDN instead of the GDN as a result of step 602, the receiving side exchange 120 performs a call processing process of connecting the call to the corresponding IDN in step 620.

If the received call is the call that calls the GDN as a result of the determination of step 602, the called side exchange 120 determines whether the GDN is idle in step 604. If the GDN is in the idle state as a result of step 604, the called side exchange 120 includes the step of providing the caller to the caller 100 of the incoming call in step 610 and step 612 according to the setting of the GDN. Perform call processing to connect the call to GDN.

If the called GDN is not in an idle state as a result of the determination in step 604, the called side exchange 120 performs a hunting process for connecting the incoming call to the idle IDN in step 606. In step 608, the called side exchange 120 includes IDN information and GDN information originally called through the hunting process of step 606 for the incoming call. In operation 610, the called party exchanger 120 provides a ring back tone according to the setting of the GDN to the caller 100 of the called call using the GDN information included in the called call. In step 612, the called side exchange 120 connects the called call to the idle IDN using the IDN information included in the called call.

As such, using the present invention performing the call processing process including the GDN information with respect to the call to the GDN, which is connected to the IDN through the hunting process, the call ring tone is different from the setting of the GDN for all the incoming calls that call the GDN. It can be provided.

 By applying the present invention as described above, it is possible to provide the ring back tone according to the setting of the GDN and the IDN of the PBX when providing the ring back tone for the caller calling the PBX subscriber.
