Description

Subscriber-based Ring-Back-Tone Service Method by control of HLR}

The present invention relates to a subscriber-based ringback tone service method through control of a home location register, and more particularly, provides a specific sound desired by a called subscriber as a ring back tone to provide a conventional ring back tone method. To improve, the present invention relates to a subscriber-based ringback tone service method through control of a home location register.

In general, when a caller attempts to make a phone call in an existing mobile communication network, the receiver of the called subscriber adopts a method of giving a uniform ringback tone to the caller. However, such a conventional ringback tone method uses a uniformly identical tone. Since the caller cannot determine whether there is a misconnection until the answer of the called party, there is also a problem that can not provide a variety of ringback tone replacement service to meet the characteristics of the user.

On the other hand, in recent years, a method of listening to various advertisement sounds instead of the uniform ringback tone has been proposed, but this also gives a caller a specific advertisement sound selected by a network operator without a subscriber's option and then a predetermined time. Since it is a way to make a free call for a while, the caller cannot determine whether there is a misconnection until the answer of the called party, and furthermore, there is a problem in that it cannot provide various ringback tone services that match the characteristics of the user.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a caller with a specific sound registered or selected by a called subscriber instead of the existing ringback tone, so that the caller determines whether there is a misconnection before the answer of the called party. It is to provide a subscriber-based ringback tone service method through the control of the home location register, and to provide a variety of ringback tone replacement to meet the characteristics of the called subscriber.

In addition, the cancellation information (including the telephone number) is transmitted from the database 80 to the home location register 10 (S402), and the home location register 10 provides the corresponding subscriber profile to the service of the present invention. The subscription is updated to be terminated (S403). In addition, the termination information (that is, subscriber deletion information) including the termination subscriber telephone number is transmitted from the database 80 to the sound source providing control server 70 at the time of termination (S404), and the sound source providing control server 70 Terminates the code of the sound source allocated in step S205 of FIG. 2 based on the received termination information. For example, if the canceled subscriber telephone number is '293-XXXX' in the database of FIG. 7, the corresponding subscriber telephone number '293' -XXXX 'and the code information' 07 'stored in association with it are deleted by deleting (S405).

FIG. 5 is a flowchart illustrating an example of a practical service procedure performed after the procedure of FIGS. 2 and / or 3 is completed in a subscriber-based ringback tone service method through control of a home location register according to the present invention. FIG. 8 is a flow chart for transmitting the corresponding sound source corresponding to the called subscriber from the originating exchange 31 to the originating terminal (not shown) with the ringback tone as shown in the database of FIG. 8.

First, when any caller requests a call connection by calling a called subscriber having the telephone number '293-XXXX' as the service subscriber of the present invention, for example, the calling exchange (O_MSC) 31 is a home location register (HLR). Request destination information to 10) (Location Request) (S501).

The home location register 10 requests routing information from the destination exchange (T_MSC) 32 according to the request of step S501 (Routing Request) (S502), and at the same time, the incoming call to the sound source providing control server 70. A sound source code corresponding to the number information '293-XXXX' is requested (S503).

The destination exchange 32 responds to step S502 by providing routing information (that is, a TLDN: Temporary Local Directory Number) corresponding to the routing number to the home location register 10 (S504). The sound source providing control server 70 searches for the stored sound source code '07' in association with the incoming call number '293-XXXX' in response to the request of step S503 and converts the found sound source code '07' into the home location register ( 10) and responds to step S503 (S505).

The home location register 10 transmits the routing information received in the step S504 to the call exchanger 31 to respond to the step S501, in particular, in response to the response message, the sound source providing control server ( The sound source code information '07' received from 70 is sent (S506).

Accordingly, the originating exchange 31 requests a trunk (or ISUP) call connection to the destination exchange 32 based on the received routing information to form a mutual call path (S507). At the same time, the 'sound source # 7' previously stored in response to the received sound source code information '07' in its database as shown in FIG. 8 is transmitted to the caller's mobile terminal in place of a ringback tone (S508).

Lastly, the call exchanger 31 stops the transmission of the sound source when the called subscriber receives a call while the 'sound source # 7' is being transmitted as the ringback tone replacement sound as described above, and stops transmitting the sound source. The call is made between the caller and the called party through the mutually formed call path (S509).

FIG. 6 is a flowchart showing another example of a practical service procedure performed after the procedure of FIG. 2 and / or 3 is completed in the subscriber-based ringback tone service method through control of the home location register according to the present invention. FIG. 8 is a flowchart for transmitting a corresponding sound source corresponding to a called subscriber from the called exchange to the calling terminal as a ringback tone, as shown in the database of FIG. 8.

First, when any caller requests a call connection by calling a called subscriber with the telephone number '293-XXXX' as the service subscriber of the present invention, for example, the calling exchanger (O_MSC) 31 returns a home location register ( Request location information to the HLR 10 (Location Request) (S601).

The home location register 10 requests a sound source code corresponding to the incoming call number information '293-XXXX' to the sound source providing control server 70 based on the request of step S601 (S602), and the sound source providing control The server 70 searches for the stored sound source code '07' in association with the incoming call number '293-XXXX' in response to the request of step S602 and transfers the found sound source code '07' to the home location register 10. It forwards and responds to the step S602 (S603).

Subsequently, the home location register 10 requests routing information from a corresponding destination exchange (T_MSC) 32 according to the request of step S601, but the received sound source code information ' 07 'is delivered to the destination exchange 32 (S604), and the destination exchange 32 sends routing information corresponding to a routing number to itself to the home location register 10 (ie, TLDN: Temporary Local Directory). Number) to respond to step S604 (S605).

The home location register 10 transmits the routing information received in step S605 to the originating exchange 31 and responds to step S601 (S606), whereby the originating exchange 31 sends the received routing. Based on the information, the destination exchange 32 requests a trunk (or ISUP) call connection to form a mutual call path (S607). When the trunk call is connected, the destination exchange 32 is shown in FIG. 8. Search for the pre-stored 'sound source # 7' corresponding to the sound source code information '07' received in step S604 in its database, and replace the searched 'sound source # 7' with the caller's mobile terminal. And send it (S608).

Lastly, the called exchange 31 stops the transmission of the sound source when the called subscriber receives a call while the 'sound source # 7' is being transmitted as the ringback tone replacement sound as described above, and stops transmitting the sound source. The call is made between the caller and the called party through the mutually formed call path (S609).
