The receiving MSC transmits a call connection response signal(313). The background sound supplying device connects a speech path with the receiving terminal, and mixes a preset background sound with the speech path(315). An originating user calls a receiving terminal user with the background sound(317).

Description

Method and apparatus for providing background sound and recording service {Method and apparatus for providing background sound and recording a telephone call}

The present invention relates to a method and apparatus for providing a background sound and recording a call during a call.

There is an increasing tendency for modern people to reveal their own personalities in the crowd. This trend is also found in voice calls using a communication network. For example, a user-selectable service (coloring, peeling, etc.), which replaces the ringback tone provided uniformly according to the ITU-T specification, has become explosive. The ring back tone replacement sound service will be described in detail as follows.

1 is a signal flow diagram illustrating a signal flow in a conventional mobile communication network for implementing the ringback tone replacement tone service.

Referring to FIG. 1, when a calling terminal requests a call connection to a called terminal corresponding to a called party subscribed to a ringback tone replacement tone service, the calling side exchange (MSC) requests called location information to a home location register (HLR). (Location Request) (step 101). The HLR requests routing information to the called side exchange (MSC) in response to the called location information request from the calling side exchange (step 103). The destination side exchange sends routing information (TLDN: Temporary Local Directory Number) to the HLR in response to the routing information request signal received from the HLR (step 105). The HLR then sends the called location information to the originating exchange using the received routing information (step 107).

The originating exchange exchange requests an ISUP call connection to the called exchange based on the routing information (step 109). The called exchange reads the ringback tone replacement tone service setting information previously stored in the storage device according to the ISUP call connection request signal transmitted from the calling exchange, and then a user corresponding to the called terminal subscribes to the ringback tone substitute tone service. In this case, the ISUP call connection request signal is transmitted to the sound source control device using the routing information corresponding to the previously stored sound source control device (step 111). In this case, the ISUP call connection request signal includes a called terminal identifier and a calling terminal identifier. As a result of performing this process, a call path is formed between the calling exchange, the called exchange and the sound source providing device.

The sound source providing apparatus requests a sound source code to the sound source providing control server based on the received called terminal identifier and the calling terminal identifier (step 113). In response to the sound source code request signal, the sound source providing control server searches for a sound source code stored in connection with the called terminal identifier and the calling terminal identifier and transmits the found sound source code to the sound source providing apparatus (step 115). Thereafter, the sound source providing apparatus transmits a ringback tone substitute sound corresponding to the sound source code received from the sound source providing control apparatus to the calling terminal through the formed call path (step 115). When the called exchange recognizes that the called terminal responds while the ringback tone replacement tone is transmitted to the calling terminal, the called exchange requests the ISUP call release to the sound source providing apparatus (step 117). The sound source providing apparatus releases the call path set as the calling terminal after receiving the ISUP call release request signal from the called exchange. Thereafter, the called terminal can perform a normal call using the call path set in the calling terminal.

The called terminal subscriber can use the above-described ring back tone substitute tone service to give the calling terminal subscriber a ring back tone substitute tone that replaces the existing uniform ring back tone selected by the calling terminal subscriber. The reason for the commercial success of the ringback tone replacement sound service may be that it satisfies the desire of modern people to express personality to some extent.

However, the ringback tone replacement tone service is terminated before the normal call between the called terminal and the calling terminal, and thus there is a problem in that the personality, mood, state, etc. of the user cannot be represented during the normal call. That is, if the called terminal user can make a normal call against the background of preset music, bird sounds, waves, mall noises, etc., explosive attention may be attracted from the user.

An object of the present invention is to provide a background sound providing method and apparatus that can provide a background sound when making a voice call between the calling terminal and the called terminal.

Another object of the present invention is to provide a call recording method and apparatus capable of recording a call when making a voice call between a calling terminal and a called terminal.
