In response to the third device joining the telecommunications link, the first device issues an alert to the second device and the third device, wherein the alert indicates that the third device has joined the telecommunications link.

## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of telecommunications and, more particularly, to conference call alerts.
A conference call is a telephone call in which the calling party wishes to have more than one called party listen in to the audio portion of the call. The conference calls may be designed to allow the called party to participate during the call, or the call may be set up so that the called party merely listens into the call and cannot speak. It is sometimes called ATC (Audio Tele-Conference).
Conference calls can be designed so that the calling party calls the other participants and adds them to the call; however, participants are usually able to call into the conference call themselves by dialing a telephone number that connects to a “conference bridge” (a specialized type of equipment that links telephone lines).
Companies commonly use a specialized service provider who maintains the conference bridge, or who provides the phone numbers and PIN codes that participants dial to access the meeting or conference call.
The more limited three-way calling is available (usually at an extra charge) on mobile, home, or office phone lines. For a three-way call, the first called party is dialed. Then the hook flash button (or recall button) is pressed and the other called party's phone number is dialed. While it is ringing, flash/recall is pressed again to connect the three people together. This option allows callers to add a second outgoing call to an already connected call.
Short Message Service (SMS) is a text messaging service component of phone, Web, or mobile communication systems. It uses standardized communications protocols to allow fixed line or mobile phone devices to exchange short text messages.

DETAILED DESCRIPTION
Embodiments of the present invention recognize that individuals can join a conference call by calling a telephone number of a conference service, in which case the callers are connected by a conference bridge. Further, three-way calling is an example of establishing a conference call without a conference bridge. However, callers may be joined into a three-way call without their knowledge or consent.
Embodiments of the present invention provide for conference calling with alerts. In a three-way calling environment, conference calls are initiated by a caller using the caller's telephone. Embodiments of the present invention provide for issuing alerts to one or more callers on a conference line in response to a new caller joining the conference line or an existing caller leaving the conference line. Such an alert may identify the new caller or existing caller.
Embodiments of the present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating a computing environment, in accordance with an embodiment of the present invention. For example, FIG. 1 is a functional block diagram illustrating computing environment 100. Computing environment 100 includes telecommunications device 102, telecommunications device 110, and telecommunications device 112, which are connected over network 120. Telecommunications device 102 includes conference call program 104.
In various embodiments, telecommunications device 102 is a computing device that can be a standalone device, a server, a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), or a desktop computer. In one embodiment, telecommunications device 102 is a smartphone or cellular phone. In various embodiments, each of telecommunications device 110 and telecommunications device 112 is a telephone, smartphone, cellular phone, or a computing device with telephonic capabilities. In another embodiment, telecommunications device 102 represents a computing system utilizing clustered computers and components to act as a single pool of seamless resources. In general, telecommunications device 102 can be any computing device or a combination of devices with access to telecommunications device 110 and telecommunications device 112, and capable of executing conference call program 104. Telecommunications device 102 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 4.
In this exemplary embodiment, conference call program 104 is stored on telecommunications device 102. In other embodiments, conference call program 104 may reside on another computing device, provided that conference call program 104 can access and is accessible by telecommunications device 102. In yet other embodiments, conference call program 104 may be stored externally and accessed through a communication network, such as network 120.
Network 120 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and may include wired, wireless, fiber optic or any other connection known in the art. In one embodiment, network 120 includes one or more cellular network connections, voice-over-internet-protocol connections, or telephonic network connections. In general, network 120 can be any combination of connections and protocols that will support communications between telecommunications device 102, telecommunications device 110, and telecommunications device 112, in accordance with a desired embodiment of the present invention.
Conference call program 104 operates to issue conference call alerts. In one embodiment, conference call program 104 issues an alert to one or more devices of callers who are members of a conference call. In one embodiment, conference call program 104 issues an alert in response to a caller joining a conference call. For example, for a conference call initiated by a first caller, conference call program 104 issues an alert to a second caller and a third caller in response to the third caller joining the conference call. In another embodiment, conference call program 104 issues an alert in response to a caller leaving a conference call. For example, for a conference call initiated by a first caller, conference call program 104 issues an alert to a second caller and a third caller in response to the second caller leaving the conference call.
FIG. 2 is a flowchart depicting operations for issuing conference call alerts, on a computing device within the computing environment of FIG. 1, in accordance with an embodiment of the present invention. For example, FIG. 2 is a flowchart depicting operations 200 of conference call program 104 on computing device 102 within computing environment 100.
In step 202, telecommunications device 102 initiates a telecommunications link between a first device and a second device. The telecommunications link enables voice communications between users of the first device and the second device. In one embodiment, conference call program 104 initiates the link in response to an interaction from a user of telecommunications device 102. In another embodiment, another function of telecommunications device 102 initiates the telecommunications link, in which case conference call program 104 detects that the link is initiated. In one example, the first device is telecommunications device 102 and the second device is telecommunications device 110.
In step 204, telecommunications device 102 receives an interaction identifying a third device. In one embodiment, conference call program 104 receives the interaction. In another embodiment, another function of telecommunications device 102 receives the interaction. The interaction identifies a communications address of the third device. For example, the communications address can be a telephone number, an internet protocol address, an email address, or another unique identifier of the third device. In one embodiment, in response to receiving the interaction identifying the third device, telecommunications device 102 initiates a second telecommunications link with the third device. For example, telecommunications device 102 receives an interaction to place the second device on hold and a subsequent interaction to initiate a second telecommunications link with the third device. In one example, the third device is telecommunications device 112.
In step 206, telecommunications device 102 modifies the telecommunications link to include the third device. In one embodiment, telecommunications device 102 merges the telecommunications link between the first device and the third device with that between the first device and the second device. The merged telecommunications link enables voice communications between users of the first device, second device, and third device. In another embodiment, the first device joins the third device directly to the telecommunications link between the first caller and the second caller rather than merging telecommunications links. In one example, conference call program 104, or another function of telecommunications device 102, modifies a telecommunications link between telecommunications device 102 and telecommunications device 110 to include telecommunications device 112.
In step 208, conference call program 104 issues an alert in response to the third device joining the telecommunications link. The alert is a notification (e.g., an SMS message, a voice message) transmitted via one or more communications protocols. For example, a first device (e.g., telecommunications device 102) establishes a telecommunications link with a second device (e.g., telecommunications device 110). In response to a third device (e.g., telecommunications device 112) joining the telecommunications link, the first device issues an alert to the second device and the third device. In this case, the alert is one or both of an SMS message and a voice announcement transmitted over the telecommunications link between the first device, second device, and third device. The alert includes information regarding the third device. In one embodiment, information identifies that a caller has joined the telecommunications link. For example, the alert identifies that a caller has joined without identifying the caller. Alternatively, the alert does identify the caller. In another embodiment, the alert identifies a communications address of the third device (e.g., a communications address received in step 204). In yet another embodiment, the alert provides an indication that the first device provided the interaction identifying the third device. For example, the alert identifies the first device as requesting the third device to join the telecommunications link. In another example, the alert identifies a name of a user of the third device, a communications address of the third device (e.g., a phone number), and an indication that the interaction (see step 204) was received from the first device. The name of a user of the third device may be provided by a user (e.g., of the first device or the third device) or a contacts database (e.g., of the first device or the third device).
In step 210, conference call program 104 monitors for further changes to membership of the telecommunications link. In one embodiment, conference call program 104 receives a notification from a carrier or telecommunications service provider identifying further changes. In another embodiment, conference call program 104 monitors for indicators that may be received from a device on the link. For example, conference call program 104 may receive an indicator from a device on the link that indicates that the device is departing the link. In one example, such an indicator may be an in-band telecommunication signal complying with a format such as dual-tone multi-frequency signaling. In yet another embodiment, conference call program 104 may receive indicators via out-of-band signaling, such as via an SMS message or data communication from another device of the link.
In step 212, conference call program 104 issues an alert in response to further changes. In one embodiment, conference call program 104 issues an alert in response to detecting that another device has joined the link. For example, conference call program 104 issues an alert in a substantially similar manner to that previously discussed in connection with step 208. In another embodiment, conference call program 104 issues an alert in response to a device leaving the link. For example, conference call program 104 receives an interaction from a user of the first device to remove the third device from the call. In this case, conference call program 104 issues an alert to one or more devices in response to the departing device leaving the link. In one embodiment, conference call program 104 determines that a device has left the link based on an indication received from the departing device or from a service provider through which the link is maintained.
FIGS. 3A-3D are functional block diagrams illustrating an example implementation of operations for issuing conference call alerts, in accordance with an embodiment of the present invention.
In FIGS. 3A-3D, user A is a user of a first device, user B is a user of a second device, and user C is a user of a third device. Each of the first device, second device, and the third device are telecommunications devices. In these figures, users A, B, and C perform actions via their respective devices.
In FIG. 3A, user A initiates telecommunications link 302 with user B (see step 202). User A interacts with the first device to identify the third device of user C (see step 204). In FIG. 3B, user A initiates a second telecommunications link 304 with user C.
In FIG. 3C, telecommunications link 302 is modified to include the first device of user A, the second device of user B, and the third device of user C, thereby forming telecommunications link 306 (see step 206). The third device of user C thereby joins the telecommunications link between user A and user B. In response to the third device of user C joining the telecommunications link, the first device of user A issues alert 310 to the second device of user B and alert 312 to the third device of user C (see step 208). In FIG. 3D, the first device of user A monitors for additional changes to the membership of telecommunications link 306 (see step 210).
FIG. 4 is a block diagram of components of a computing device, generally designated 400, in accordance with an embodiment of the present invention. In one embodiment, computing device 400 is representative of telecommunications device 102 within computing environment 100, in which case telecommunications device 102 includes conference call program 104.
