1. Field of the Invention
The invention relates generally to relay call transfer services for hearing-impaired communications, and, more specifically to a method, system and device for building user profiles for deaf or hearing-impaired users and providing relay call transfer services for hearing-capable users.
2. State of the Art
Relay services are used to facilitate the communication between hearing-capable and hearing-impaired users. To interface a hearing-impaired user into a generally voice-based communication system, services are employed allowing hearing-impaired users to communicate with a relay service, namely through an interpreter or a communication assistant. A hearing-impaired user can effectively communicate with a hearing-capable user in a remote location through a relay service using various communication services and devices. Current relay services include VRS (Video Relay Services), VCO (Voice Carry Over), IP-Relay, CAPTel, and TTY.
Depending on the service that is provided, a different communication device is required on the part of both the hearing-impaired user and the interpreter or communication assistant of the relay service. For example, in a VRS call, the hearing-impaired user and the interpreter uses a video phone or web camera and the associated software to communicate back and forth using IP-based video. In an IP-Relay call, the hearing-impaired user and the communication assistant uses either some form of browser-based tool on two PCs connected over the Internet or a cellular-based hand held device used by the hearing-impaired user connected to a browser-based application used by the communication assistant.
Hearing-impaired users typically initiate calls to a hearing-capable user at a fairly high success rate. Conversely, because a hearing-impaired user does not always have immediate access to all of his or her personal communication devices, a call from a hearing-capable user to a hearing-impaired user is not always as successful. For example, when a hearing-capable user wishes to contact a hearing-impaired user via a video phone, the hearing-capable user initiates a communication session by entering, in a voice phone, the phone number of the VRS. The VRS then attempts to establish a connection with the hearing-impaired user via a video phone located in the hearing-impaired user's office or home. If the hearing-impaired user is not in his or her office or home, the call cannot be completed and the communication session cannot take place.
Therefore, in order to provide greater ease and efficiency for users of hearing-impaired communication services, a need exists for improving the call completion rate of a hearing-capable user to a hearing-impaired user.
The present invention is directed to a method, system and device for relay call transfer services in a deaf or hearing-impaired communication system. In one embodiment of the present invention, a method for providing a communication session is provided. The method includes entering into a voice phone a called party number of a relay service and establishing a first segment of a communication session between the voice phone and the relay service. The method further includes retrieving a profile of a relay service user and establishing a second segment of the communication session between the relay service and a communication device.
In another embodiment of the present invention, a relay service communication system is provided. The system includes at least one communication device and a relay service device configured to receive a voice phone call and establish a first segment of a communication session. The relay service device is further configured to store at least one user profile. The system also includes at least one communication link for transmitting signals of the at least one communication device and relay service device. In addition, the system includes at least one call service system associated with the at least one communication device.
In a further embodiment of the present invention, a relay service device is provided. The device includes control logic configured to establish a first segment of a communication session with a voice phone. The control logic is further configured to establish a second segment of the communication session with a communication device. The device also includes storage configured to store a profile corresponding to a relay service user.
In the drawings, which illustrate what is currently considered to be the best mode for carrying out the invention:
Relay services provide assistance in a communication session between a hearing-capable user and a hearing-impaired user. One application of a relay service is to assist a hearing-capable caller in an attempt to contact and communicate with a hearing-impaired individual. Relay services typically provide a variety of services in several areas for hearing-impaired communications. These services can include, but are not limited to, video relay services (VRS), voice carry over (VCO), IP-Relay, CAPTel, and TTY. Based on the service that is used, a corresponding electronic communication device is required on the part of both the hearing-impaired user and the relay service interpreter or communications assistant. Many electronic devices for relaying communicative expressions of both hearing-capable and hearing-impaired users currently exist. These devices can include, but are not limited to, video phones, web cameras, hand-held text messaging devices, and IP-based CAPTel phones. The communicative expressions, such as sign language and/or text messaging, may be interpreted or relayed by a translation or interpretive service, such as a relay service, while a hearing-capable user may interact in a conventional manner with the relay service through the use of a voice-based dialogue conveyed either over a conventional voice phone or another communication device.
Currently, a need exists to improve the ability of a hearing-capable user to contact and communicate with a hearing-impaired user. Often, a hearing-capable caller attempts to contact a hearing-impaired individual via a single communication device, and, at the time, the hearing-impaired individual does not have immediate access to the device. Consequently, the call fails and the desired communication does not take place. In many cases, unbeknownst to the hearing-capable caller, a hearing-impaired individual has alternate communication devices on which he or she could be reached. Thus, there is a desire to take advantage of the alternate communication devices used by a hearing-impaired individual to improve the successful call connection rate.
In one embodiment of the present invention, a hearing-capable user initiates a communication session by entering, in a voice phone, the phone number of a relay service which the caller selected to provide assistance in the communication. The call is then received by the relay service and the caller provides the relay service with the contact number of the hearing-impaired individual with whom the caller wishes to speak. The contact number is used to identify and access a user profile for the hearing-impaired individual stored on the relay service server. Included in the user profile, among other data, would be a list of the user's preferred communication devices ordered from most to least preferred. The relay service then transfers the call request to the appropriate service system corresponding to the most preferred communication device listed in the hearing-impaired user's profile. An interpreter or communications assistant then attempts to establish a connection to the hearing-impaired user via the appropriate communication device. If the call is answered, the communication session proceeds to take place with the assistance of the interpreter or communications assistant. Alternatively, if the hearing-impaired user does not answer the call, the service system automatically transfers the hearing-capable caller, and all the associated data pertaining to the call, to the service system that handles calls according to the hearing-impaired user's next most preferred communication device. This process can continue until the hearing-impaired user ultimately answers the call or until attempts have been made to contact all of the preferred communication devices defined in the hearing-impaired user's profile.
To interface a hearing-impaired user into a generally voice-based communication system, relay services are employed allowing a hearing-impaired user to communicate with an interpreter or a communication assistant. A hearing-impaired user may successfully communicate with a hearing-capable user in a remote location through a relay service using a variety of communication services and devices. Current relay services include, but not limited to, VRS (Video Relay Services), VCO (Voice Carry Over), IP-Relay, CAPTel, and TTY. Hearing-capable user 14 interacts in a conventional manner with relay service 20 through the use of a voice-based dialogue conveyed over a conventional voice phone 22.
The various devices, such as a communication device 12 and conventional voice phone 22, are coupled with a relay service 20 using one or more networks 17, 18. To facilitate the enhanced bandwidth needs of a video phone or web camera, network 17 may be implemented as a high bandwidth network such as a DSL, Cable, Ethernet or other enhanced-bandwidth networking technology. Network 18 may be implemented according to the standards and bandwidth requirements of conventional voice phone 22.
In one embodiment of the present invention, a hearing-capable user 14 initiates a voice phone call to the relay service 20. The call is received by the relay service 20 and the hearing-capable user 14 provides the relay service 20 with the contact number of the hearing-impaired user 16 with whom the caller wishes to speak. The relay service 20 then attempts to establish a connection with the hearing-impaired user 16 via a communication device 12 that may include, but is not limited to, a video phone, a web camera, a text messaging device, or an IP-based CAPTel phone. The communication devices are required on the part of both the hearing-impaired user and the video relay service interpreter or communication assistant. Based on the communication device that is used, an appropriate service is required. These services may include, but are not limited to, Video Relay Services (VRS), Voice Carry Over (VCO), IP-Relay, CAPTel, and TTY.
After successfully accessing the user profile 50, and determining the user's preferred communication device 52, the relay service 20 routes the call to an appropriate call service system 60A, 60B, 60C, 60D, 60E, and, in turn attempts to establish a connection to the user's preferred communication device 12. If the relay service 20 fails to establish a connection with the most preferred communication device, the relay service 20 can transfer the call to a second call service system that corresponds to the hearing-impaired user's second most preferred communication device. This process can continue until the relay service 20 has attempted to establish a connection with all of the defined preferred communication devices 52 listed for the hearing-impaired user.
For example, and not by way of limitation, when the relay service 20 looks up a hearing-impaired user's profile 50 and determines that the user's preferred communication device is a video phone, the relay service creates a call in the database and the call request is put in the appropriate call queue 220 viewable to the video phone call service system 60. A video relay service (VRS) interpreter then takes the call out of the call queue 220, and, in doing so, automatically transfers the phone call to the interpreter, thus connecting the hearing-capable caller and the interpreter. The relay service 20 subsequently attempts to contact the hearing-impaired user on his or her video phone communication device 12. If the hearing-impaired user does not answer the VRS interpreter, the interpreter asks the hearing-capable caller if he or she would like the relay service to attempt to contact the hearing-impaired user on his or her next most preferred communication device (such as, in this case, a hand-held paging device). If the caller wishes to try the alternate device, the VRS interpreter then transfers the call request, and all of the associated data, to the call service system 60 that handles the IP-Relay calls. The call is then placed in the appropriate call queue 220 servicing IP-Relay calls. An IP-Relay communications assistant then takes the call out of the call queue 220, and, in doing so, automatically transfers the phone call to the communications assistant. The communications assistant then attempts to contact the hearing-impaired user on his or her hand-held paging device. This process can continue until the hearing-impaired user answers the called communication device, or until the relay service 20 has attempted to establish a connection with all of the defined preferred communication devices 52 for the hearing-impaired user.
Conversely, if the hearing-impaired user does not answer 100 the video phone call, the relay service asks the hearing-capable user if he or she wishes to try contacting the hearing-impaired user on his or her alternate device (in this case, on his or her hand-held paging device) 102. If the caller does not wish to proceed, the call is terminated 106. If the caller wishes to proceed, the VRS interpreter transfers the call request, and all associated data, to the call service system that handles IP-Relay calls. The call is then placed in the appropriate queue servicing IP-Relay calls 108 and an IP-Relay communications assistant takes the call and attempts to contact the hearing-impaired user on his or her hand-held device 110. This process can continue until the hearing-impaired user answers the called communication device or until the relay service has attempted to establish a connection with all of the defined preferred communication devices for the hearing-impaired user.
Alternatively, if the call is not answered, the interpreter or communications assistant 230 asks the hearing-capable user if he or she wishes to try contacting the hearing-impaired user on his or her alternate device. If the hearing-capable caller wishes to proceed as illustrated by phase 2, the call request 200 is forwarded to the appropriate queue 220 located in the service system 60 that handles calls relating to the hearing-impaired user's second most preferred communication device. When an interpreter or communications assistant 230 is ready to receive the call request, the call is transferred 204 and the hearing-capable user is connected to the interpreter or communications assistant 230. The service system 60 then attempts to connect 206 with the hearing-impaired user on the specified communication device 12. If the hearing-impaired user answers the call, the communication session is established.
Otherwise, if the hearing-impaired user does not answer the call, the relay service 20 can continue attempting to reach 206 the hearing-impaired user according to a third most preferred communication device 12 as illustrated by phase 3. Ultimately this process can continue until the relay service 20 has attempted to establish a connection with the hearing-impaired user on his or her nth most preferred communication device 12 as illustrated by phase n.
