## Title
Calling party controlled ringback tones

## Abstract

A computer readable medium stores a program for a calling party controlled ringback tone service. The service enables a calling party to control ringback tones, even overriding called party selected ringback tones. The service can operate in a wireless or wireline network, such as a voice over IP (VoIP) network or time division multiplexed (TDM) network. The calling party can be periodically billed for the ringback tone control service, as well as the ringback tones. The subscriber can configure the service via the web.

## Background
BACKGROUND
1. Field of the Disclosure
The present disclosure relates to telecommunications. More particularly, the present disclosure relates to controlling ringback tones heard by a calling party.
2. Background Information
Wireline service providers, wireless service providers, and voice over IP (VoIP) service providers offer ringback tone (RBT) services. The basic service allows a user to purchase a ringback tone, which can be downloaded to the network. A ringback tone can be a tone, an audio file, a video file, etc. When a caller calls a party that has subscribed to ringback tone service, the ringback tone is played to the calling party, instead of the current standing ringing signal/tone. A ringback tone can be assigned as a default to all incoming numbers, a group of numbers or a single number. A customer can purchase/lease multiple ringback tones.
A problem with current ringback tone services is that the calling party has no control over what he hears once he dial a phone number and are waiting for the call to be established. That is, a calling party currently has no control over what ringback tone or message is being played in lieu of a ringing signal. The lack of control is particularly troublesome when callers find the ringback tone selected by the called party to be annoying or even offensive. Compounding the problem is the fact that the service provider does not have control over messages coming from “off network.” Thus, a need exists for the ability to block or substitute for the ringback tone played by the called party.

DETAILED DESCRIPTION
In view of the foregoing, the present disclosure, through one or more of its various aspects, embodiments and/or specific features or sub-components, is thus intended to bring out one or more of the advantages as specifically noted below.
The present disclosure pertains to calling party controlled ringback tones. The control permits blocking of called party selected ringback tones, and could include the playing of a substitute ringback tone that the calling party has chosen. The substitute ringback tone could be a tone that the calling party has purchased/leased or a standard ringing tone. This feature gives the calling party control over what they hear while waiting for the call to be completed.
In one aspect of the present invention, a computer readable medium stores a program for a calling party controlled ringback tone service that enables a calling party to control ringback tones. The medium includes a ringback tone receiving code segment that receives a ringback tone selection from the calling party; and a ringback tone playing code segment that plays the ringback tone selection to the calling party when the calling party places a call to a called party. The medium also includes a ringback tone terminating code segment that stops playing the ringback tone selection when the called party answers the call.
In one aspect, the ringback tone playing code segment overrides a called party selected ringback tone. The ringback tone receiving code segment can receives the selection via the web. The ringback tone selection can be a list of ringback tones and the ringback tone playing code segment can play a first ringback tones from the list, during a first call and a different ringback tone from the list during a second call.
In another aspect, the medium also includes a service billing code segment that periodically generates a bill to the calling party for the calling party controlled ringback tone service. The period can be a monthly period. A ringback tone billing code segment can also be provided to generate a bill to the calling party for each ringback tone downloaded by the calling party.
In yet another aspect, the ringback tone receiving code segment receives an association between ringback tones and destinations. The ringback tone selection can be a standard ring tone. An activating code segment can be provided to receive an activation signal from the calling party during the call, the activation signal indicating that the calling party desires to override a called party selected ringback tone.
In another aspect, a calling party controlled ringback tone system executes a calling party controlled ringback tone service. The system includes a media server that plays a ringback tone selected by a calling party when the calling party places a call to a called party.
The system can also include a service control point that determines whether the calling party subscribes to the service, the service control point directing the call to the media server when the calling party is determined to be a subscriber.
In one aspect, the media server reviews a profile of the calling party to determine the selected ringback tone. The media server can originate another call from the media server to the called party in response to the call placed by the calling party. The media server can instruct a call transfer that creates a call path connecting the calling party to the called party and can also remove itself from the call path in response to the called party answering.
The system can also include a call control element operating in a voice over IP (VoIP) environment. The call control element detects when the calling party has subscribed to the service. The call control element can instruct a voice channel to be set up between the media server and an IP device of the calling party when the calling party subscribes to the service. The call control element can check a profile of the calling party to determine the selected ringback tone. The call control element can instruct disconnection of the voice channel between the media server and the IP device of the calling party when the called party answers the call. The media server can play the ringback tone selected by the calling party while overriding a called party selected ringback tone.
Referring to FIG. 1, a description is now provided of an illustrative embodiment of a general computer system 100, on which the calling party controlled ringback tone service functionality can be implemented.

Referring to FIGS. 2 and 3, an exemplary time division multiplexed (TDM) call flow is described.
In the following example, a calling party 205 places a call to a called party 210. The call is via two service switching points (SSPs) 215, 220, although more or fewer SSPs could be involved. A service control point (SCP) 225 communicates with the SSPs 215, 220 via service transfer points (STPs), which are not shown. A media server 230 is also provided. An exemplary media server is an enhanced media resource server (eMRS) available from Lucent Technologies, Inc. In one embodiment, the media server 230 connects to an SSP (SSP 215 in FIG. 2) via an ISDN primary rate interface (PRI). Of course, the media server 230 is not limited to being connected to SSP 215, nor is the interface limited to PRI.
At step S300, the calling party 205 lifts the handset, dials digit and places a call to the called party 210, thus initiating a connection to the originating SSP 215. The terms calling party and called party are used in this specification, although it is understood that the terms cover either the person or the device, whichever is appropriate. An originating trigger placed on the line causes a query to be placed to the SCP 225, at step S305. The SCP 225 determines whether the calling party 205 subscribes to a calling party controlled ringback tone service. If so, at step S310 the SCP 225 instructs the originating SSP 215 to connect to the media server 230. In another embodiment, the SCP 225 instructs the media server 230 to connect to the SSP 215. In response, at step S315, the originating SSP 215 connects to the media server 230, for example, via a primary rate interface. At this point, the media server 230 can check a profile of the calling party 205 to determine the ringback tone selected for playing to the calling party 205. In an alternative embodiment, the SCP 225 determines the selected ringback tone prior to step S310 and sends information indicating the selection to the SSP 215 at step S310 and to the media server 230 at step S315.
Selection of the ringback tone, as well as other service configurations can be performed by the subscriber via a web interface to the media server 230, or in an alternative embodiment, to the SCP 225. For example, the subscriber 205 can assign different ringback tones to different destination numbers. The calling party 205 could also create a list of ringback tones. In this case, each call could play a different ringback tone from the list. That is, a first call could play the first ringback tone from the list and then the next call could play the next ringback tone from the list. The subscriber 205 could also control activation and deactivation of the service via the web interface (or possibly via a control code before or during the call).
After the media server 230 determines the selected ringback tone or is informed of the ringback tone selection, at step S320, the media server 230 plays the selected ringback tone to the calling party 205 while the calling party 205 waits for the called party 210 to answer the phone. Next (or at approximately the same time or even prior), the media server 230 originates a call to the called party 215 by contacting the SSP 220, at step S325 and it is determined whether the called party is off hook. In the exemplary configuration shown in FIG. 2, the call is connected via the primary rate interface, the originating SSP 215, the trunk connecting the SSPs 215, 220, and the terminating SSP 220.
In response to the call from the media server 230, at step S330 the SCP 225 sends an authorize termination message to the terminating SSP 220, in a known manner. The authorize termination message causes the SSP 220 to ring the called party 215, at step S335. If the line is determined to be busy, an appropriate recorded announcement/tone would substitute for the ringback tone already started (or could altogether replace the ringback tone).
When the called party 215 answers the call, an off hook signal is sent to the SSP 220 at step S340. Once answer supervision is received, the ringback tone is halted and the call is completed. More specifically, in response to receiving the off hook signal, at step S345 the SSP 220 informs the media server 230. In a known manner the media server 230 then instructs a two bearer channel call transfer (2BCT) to connect the calling party 205 to the called party 215, at step S350. In one embodiment, the media server 230 drops out of the call path. In an alternative embodiment, the bridge is not performed and the media server 230 stays in the call path for the duration of the call.
Although a TDM network has been described, the present invention contemplates alternative networks. For example, a wireless network or a voice over IP (VoIP) network could also accommodate the calling party controlled ringback tone service. The exact deployment of the calling party controlled ringback tone service may vary slightly in different networks, but the resulting service will be very similar. A description of the service within a VoIP network will now be described with reference to FIGS. 4 and 5 as one example of an alternative network.
In the following example, a calling party 405 initiates a call to a called party 410 via an IP network 400 at step S500. The equipment for placing the call could be, for example, an IP PBX or a VoIP telephone. A call control element (CCE) 420, such as a VoIP server receives indication (via a VoIP Signaling protocol such as SIP/MGCP/H.323 or others) of the initiated call request at step S500 and determines whether the calling party subscribes to the calling party controlled ringback tone service. If so, the CCE 420 send a setup message (invite) to the media server 230 at step S505. The media server 230 can connect to the IP network via an IP interface, and can be the same media server as shown in FIG. 2.
In response, at step S510, the media server 230 replies to the CCE 420 with a acknowledgment message. The CCE 420 then sends instructions (acknowledgement message) to the calling party 405 to set up a voice channel (e.g., a real time transfer protocol (RTP) session if using SIP) to the media server 230 at step S515. At step S518 the voice channel is established.
At this time, the media server 230 can check a profile of the calling party 405 to determine the ringback tone selected for playing to the calling party 405. In an alternative embodiment, the CCE 420 can determine the selected ringback tone and can send information indicating the selection to the media server 230.
In either case, after the selected ringback tone is determined, at step S520, the media server plays the selected ringback tone to the calling party 405 while the calling party 405 waits for the called party 410 to answer the phone. Next (at approximately the same time or even prior), the CCE 420 sends an invite message to the called party 410 (to determine if the line is free), at step S525, causing the called party device 410 to ring. If the line is determined to be busy, an appropriate recorded announcement/tone would substitute for the ringback tone already started (or could altogether replace the ringback tone).
When the called party 410 answers the call, an acknowledgement message is sent to the CCE 420 at step S530. In response to receiving the acknowledgement message, at step S535 the CCE 420 sends a disconnect message to the media server 230, and/or the calling party device 405 at step S538, disconnecting the voice channel between the media server 230 and the calling party device 405. In one embodiment, the CCE 420 instructs one of the devices to disconnect and that device instructs the other device to disconnect. In a known manner, at step S540 the CCE 420 then instructs the calling party device 405 to set up a voice channel (e.g., an RTP session) to the called party device 410. At step S545 the voice channel is established. Although not shown in FIG. 5, the media server 230 could initiate a call to the called party 410 and bridge the two legs of the call, similar to as described above with respect to a TDM network.
In one embodiment, the calling party controlled ringback tone is played, even when the called party subscribes to a ringback tone service that would otherwise play a called party selected ringback tone to the calling party. That is, the new feature would “block” the ringback tone played by the called party. Of course, the calling party ringback tone could also be played instead of the standard ring tone, such as the well known 440 Hz and 480 Hz signal, substituting a ringback tone that the calling party has chosen.
In one embodiment, the calling party could react to the called party selected ringback tone by activating the calling party controlled ringback tone service during the call, and even after the called party's telephone begins ringing. For example, the calling party could depress keys on the telephone (e.g., #21) to start his own ringback tone, so that the called party ringback tone is overridden. In another embodiment, the calling party ringback tone is played for all calls (without additional user action), so long as the service is activated.
In one embodiment, the service provider charges a recurring fee, such as a monthly charge, to the subscriber of the calling party controlled ringback tone service. The provider may or may not limit the number of ringback tones selected on a monthly basis. In another embodiment, the calling party selected ringback tone is purchased. In this embodiment, the service provider could charge a monthly subscription fee for the service in addition to a fee for each ringback tone selected.
In still another embodiment, the calling party selected ringback tone is a standard ringing tone. In yet another embodiment, the calling party selected ringback tone is a message created by the calling party and uploaded to the media server in a well know manner.
The disclosed embodiments are advantageous. For example, as ringback tone services become more prevalent, customers will be willing to pay for, or may even demand a control/block/substitute ringback tone service to avoid listening to a ringback tone selected by the calling party. The present disclosure enables service providers to meet this demand by providing a calling party controlled ringback tone service that allows the calling party to control the ringback tone that the calling party hears.
