Abstract

PURPOSE: A subscriber-based ringback tone service method using system routing data is provided to judge an error connection before the response of a termination subscriber and offer various ringback tone substitution sounds suitable for the characteristic of the termination subscriber by providing a specific sound registered or selected by the termination subscriber to a caller instead of the conventional progress tone and ringback tone. CONSTITUTION: An origination MSC(Mobile Switching Center)(31) requests a trunk or ISUP(Integrated Services Digital Network User Part) call connection to only a termination MSC(32) on the basis of a response message from an HLR(Home Location Register)(10) and configures a mutual trunk channel(S506). The origination MSC(31) searches routing information corresponding to a telephone exchange number of a termination subscriber from a database, requests the ISUP call connection to an IP(50) corresponding to searched routing information, and configures a mutual trunk channel(S507). If the channel with the origination MSC(31) is configured, the IP requests a sound source code to an IP server(70) on the basis of provided termination telephone information(S508). The IP server(70) searches a sound source code connected to the provided telephone number, and transmits the searched sound source code to the IP(50)(S509). The IP(50) searches a sound source corresponding to the received sound source code from the database, reproduces the searched sound source, and transmits the sound source to a caller through the configured channel(S510).

A flowchart illustrating a subscriber-based ringback tone service method using system routing data.

First, when an arbitrary caller calls a service subscriber (hereinafter referred to as a called subscriber) of the present invention and requests a call connection, the calling exchange 31 requests the called location information from the home location register 10 (Location). Request) (S501).

The home location register 10 requests routing information from the corresponding destination exchange 32 according to the request (Routing Request) (S502), and accordingly, the destination exchange 32 routes to the home location register 10. It responds by providing the information (that is, Temporary Local Directory Number (TLDN)) (S503).

The home location register 10 transmits the routing information to the originating exchange 31 and responds to step S501. In particular, the home location register 10 checks the subscriber profile in response to whether the called party is the service subscriber of the present invention (that is, the called party). After checking whether the terminal is subscribed to the service of the present invention) (S504), if it is not a subscriber, it is sent to the originating exchange 31 including only TLDN information in the response message for the called location information request in the same manner as the conventional method. If the subscriber (S505-1), and the subscriber is included in the response message, the service subscription information of the present invention (that is, the information indicating that the receiver is a subscriber) is sent down to the originating exchange (31) (S505-2).

As an example of the method of transferring the service subscription information, as shown in FIG. 9, the reserved field of the additional service parameter CallingFeaturesIndicator2 is used as the ringback tone field (Specific RingBackTone: SRBT) to perform the SRBT. In the field, two bits of data (eg, '10' is a service subscription but is inactive, '11' is a service subscription and an active state) are included in the location registration response message to be included in the home location register 10. It is delivered to the destination exchange 32. For reference, the VMSB field of FIG. 9 has a Voice Mail Service Busy state, the VMSU field has a Voice Mail Service Busy Unconditional state, and the VMSNA field has a Voice Mail Service Busy Answerer. (Voice Mail Service Busy No Answer) status, FMSNA field is Fax Mail Service No Answer status, FMSB field is Fax Mail Service Busy status, FMSU field is Fax mail Fax Mail Service Unconditional status, MC field is Multi-Call, CC field is Conference Call, MUDN field is Multiple Unit Directory Number. Represents an additional service represented by 2-bit data, respectively.

The originating exchange 31 transfers the trunk only to the destination exchange 32 based on the response message provided according to the result of performing the step S505-1 or the step S505-2 from the home location register 10. trunk (or referred to as ISUP) to request a call connection to form a mutual trunk call path (S506), or at the same time, based on the telephone number of the called party, as shown in FIG. ; The routing information corresponding to the called party's station number is searched in its own database where routing information to IP # n, ... IP # (n + 1)) is divided and stored, and the sound source corresponding to the found routing information Requesting the ISUP call connection to the providing device 50 also forms a mutual trunk call path. If the called subscriber's phone number is '293-XXXX', routing information corresponding to the '293' station number, that is, the sound source providing device ( 50; IP # n, After routing information to IP # n among the IP # (n + 1) is searched for, routing is performed to the sound source providing device 50 (IP # n) having the found routing information (S507).

That is, according to step S505-1, the originating exchange 31 requests an ISUP call connection only to the destination exchange 32 to form a call path, as in the past, and according to step S505-2, If the service subscription information is '10' to request the ISUP call connection only to the destination exchange 32 to form a call path, if '11' to both the destination exchange 32 and the sound source providing device 50 A request for ISUP call connection is established to establish a call path, and when the call connection request is made, the called phone number as identification information of the called party and the outgoing phone number as caller identification information are also provided. As a result, a call path is formed between the originating exchange 31 and the destination exchange 32 when the step S506 is solely performed, and the originating exchange 31 and the incoming call when the steps S506 and S507 are simultaneously performed. A call path is formed between the exchange 32 and between the originating exchange 31 and the sound source providing device 50.

Then, the sound source providing device 50 controls the sound source providing based on the received incoming phone number information (eg, '293-XXXX') when a call path with the originating exchange 31 is formed in step S507. Request the sound source code to the server 70 (S508), the sound source providing control server 70 is the received incoming telephone number '293-XXXX in its database built as shown in Figure 7 in response to the request of step S508 Search for the specified sound source code '07' in association with ',' and transfer the searched sound source code '07' to the sound source providing device 50 in response to step S508 (S509), and the sound source providing device 50 Search for the sound source # 7 corresponding to the received sound source code '07' in the database built as shown in FIG. 8 and play the searched sound source # 7 to transmit to the caller through the formed call path instead of ringback tone ( S510).

The call exchanger 31, when the receiving subscriber receives a call while the sound source # 7 is being transmitted to the ringback tone as described above, requests the sound source providing device 50 to release the ISUP call, and the sound source providing device 50 ) To release the call (S511). At the same time, a call is made between the caller and the called subscriber through the call path mutually formed with the called exchange 31 (S512).
