## Background
TECHNICAL FIELD
The present application generally relates to a method, a system and an apparatus for providing a video call service.
BRIEF DESCRIPTION OF RELATED DEVELOPMENTS
Video calls are widely used as a communication method providing people not only speech but streaming video of the other party as well. High-speed telecommunication networks enable video call activation between computers and cellular phones.
However, using computers or cellular phones for video calls has certain drawbacks. A complex registration and device configuration regime may be needed until the video call is available. Account creation for a video call service may require a number of steps by the user and understanding of the related technology and terminology. Furthermore, users need to be aware of available services that they may even registrate for, as well as the contact information of the peer entities they may want to contact with the services. Finally, existing consumer services are targeted towards individual users—the constraints of which are categorically inappropriate for groups (e.g. families, company units, etc.) using shared devices. The very notion of identity, accounts, credentials and system management are not addressed in any meaningful our useful way.
Thus, a solution is needed that is easy to set-up, easy-to-use, low maintenance (e.g. software updates, account credential management, etc.), low-cost and highly-functional to provide video call service for the user.

DETAILED DESCRIPTION
In the following description, like numbers denote like elements.
FIG. 1 shows a schematic picture of a system 100 according to an example embodiment. A user apparatus, such as a videophone apparatus 120 may comprise a mobile terminal comprising a communication interface, for example. The videophone apparatus 120 is capable of downloading and locally executing software program code. The software program code may be a client application of a service whose server application is running on a server apparatus 130, 132 of the system 100. The videophone apparatus 120 may comprise a camera 121 for providing video stream for the video call and a microphone for providing audio stream for the video call, for example. In an embodiment, the videophone apparatus 120 may comprise a ringer or a notification speaker. The videophone apparatus 120 is configured to be connectable to a wireless communication network 140 over a wireless connection 122. The wireless connection 122 may comprise a mobile cellular network or a wireless local area network (WLAN), for example. The wireless communication network may be to a public data communication network 150, for example the Internet, over a data connection 141. The videophone apparatus 120 is configured to be connectable to the public data communication network 150, for example the Internet, directly over a data connection 124 that may comprise a fixed broadband access.
In an embodiment, the system 100 comprises an A/V output apparatus 110 configured to be connectable to the videophone apparatus 120 over a local connection 123. The local connection 123 may comprise a wired connection or a wireless connection. The wired connection may comprise Universal Serial Bus (USB), High-Definition Multimedia Interface (HDMI), SCART interface or RCA interface, for example. The wireless connection may comprise BluetoothTM, Radio Frequency Identification (RF-ID) or wireless local area network (WLAN), for example. Near field communication (NFC) may be used for device identification between the A/V output apparatus 110 and the videophone apparatus 120, for example. The A/V output apparatus 110 may comprise a television, for example.
In an embodiment, the videophone apparatus 120 is a videophone input apparatus not comprising a display but using an external display apparatus, such as an A/V output apparatus 110 for presenting information to the user.
In an embodiment, the videophone apparatus 120 is a dongle apparatus. Connecting the dongle apparatus 120 to the external display apparatus, such as an A/V output apparatus 110, the videophone service may be unlocked. The dongle apparatus 120 may be, for example, a wireless USB modem connected to a USB port of the A/V output apparatus 110, such as a television. After the connection, videophone application software and hardware/software/service credentials may be downloaded from the dongle apparatus 120 to the A/V output apparatus 110 and the videophone service unlocked. After the service is unlocked, service may be used, remote configuration may be done and metrics provided. The dongle solution provides easy to install and use for the user and a control point for the service operator utilizing, for example, a subscriber identity module (SIM) of the dongle apparatus 120.
In an embodiment, the system 100 comprises a server apparatus 130, which comprises a storage device 131 for storing service data, service metrics and subscriber information, over data connection 151. The service data may comprise configuration data, account creation data, peer-to-peer service data over cellular network and peer-to-peer service data over wireless local area network (WLAN), for example. The service metrics may comprise operator information for use in both user identification and preventing service abuse, as the device 120 and the user account are locked to a subscriber of an operator network using the subscriber identity module (SIM) of the device 120 and the service account details.
In an embodiment, service data may travel over different paths. A first path may comprise sending configuration information over a wireless communication network 122, 140, 142 from the server apparatus 130. A second path may comprise sending account creation data between the server apparatus 130 and a peer-to-peer service apparatus 160 over the data connection 150, 151, 161, for example.
In an embodiment, a proprietary application in the videophone apparatus 120 may be a client application of a service whose server application is running on the server apparatus 130 of the system 100 and whose peer-to-peer client application is running on the peer-to-peer service apparatus 160. The proprietary application may capture the user input data for the videophone service and provide the user output data, from the peer, for the videophone service using output devices of the videophone apparatus 120 or using the A/V output apparatus 110 over the local connection 123. In an embodiment, configuration information between the videophone apparatus 120 and the system server 130 is transceived via the first wireless connection 122, 140, 142 automatically and configured by the server apparatus 130. Thus the user of the videophone apparatus 120 may not need to do any initialization or configuration for the service. The system server 130 may also take care of account creation process for the service, such as videophone service between the videophone apparatus 120 and the peer 160.
In an embodiment, the system 100 comprises a service provider server apparatus 132, for storing service data, service metrics and subscriber information, over data connection 152. The service data may comprise service account data, peer-to-peer service data and service software, for example. The service provider server apparatus 132 may provide the video call service for the video phone apparatus 120 and the peer 160, whereas the system server 130 is responsible for negotiating account information and client applications for the videophone apparatus 120 with the service provider server apparatus 132.
In an embodiment, a proprietary application in the videophone apparatus 120 may be a client application of a service whose server application is running on the server apparatus 132 of the system 100 and whose peer-to-peer client application is running on the peer-to-peer service apparatus 160. The proprietary application may capture the user input data for the videophone service and provide the user output data, from the peer, for the videophone service of the service server 132 using, for example, the A/V output apparatus 110 over the local connection 123. In an embodiment, configuration information between the videophone apparatus 120 and the system server 130 is transceived via the first wireless connection 122, 140, 142 automatically and configured by the system server apparatus 130. Furthermore, the system server apparatus 130 may automatically create a service account in the service server 132, for the videophone apparatus 120. Thus the user of the videophone apparatus 120 may not need to do any initialization or configuration for the service. Thus, the system server 130 may take care of account creation process for the service, such as videophone service between the videophone apparatus 120 and the peer 160.
In an embodiment, the system server apparatus 130 not only configures and creates the account, but also facilitates editing of account credentials (where applicable). For example, when the username created for any 3rd party service (such as Skype, for example) must be unique (within that service) the name used by the videophone system service (nickname, screen name, etc.) can be non-unique, and editable. The server 130 may generate a short user-friendly name upon account creation (e.g. “smile0032”) that the user can later personalize. This may be done using a web application. The first time the users sign-in, they will be asked, for example, “what would you like to call your TV”. In response, they can change it from “smile0132” (the generated name) to “Jones family TV” (personalized name). Such modification will be sent from the system server apparatus 130 to service server 132 (Skype, Gtalk, etc.) as a “profile edit”. These “Names” have very nice properties. Firstly, they are often prioritized in contact search results. Secondly, they are not required to be unique. Thus the videophone service system does not need to check for availability within any service. The ultimate goal here is that one videophone service name can be reused across all subsequent services.
In an embodiment, a user of the videophone apparatus 120 can make and receive video calls and contact requests from a contact list relating to any peer regardless of the underlying service—without having to manage accounts (account creation, sign-in, etc.) or install multiple applications. Such solution harmonizes service fragmentation, simplifies set-up, supports a shared (family) account and reduces complexity in the context of video calling on TV.
In an embodiment, authentication of a videophone apparatus 120 on a system server 130 may utilize hardware or SIM credentials, such as International Mobile Equipment Identity (IMEI) or International Mobile Subscriber Identity (IMSI). The videophone apparatus 120 may transmit authentication information comprising IMEI and/or IMSI, for example, to the system server 130. The system server 130 authenticates the videophone apparatus 120 by comparing the received authentication information to authentication information of registered users stored at the system server database 131, for example.
In an embodiment, after authentication step, the system server 130 may initiate automatic account generation for third party video call services provided by service provider servers 132, such as Skype or Gtalk, for example.
In an embodiment, incoming video call requests from peers 160 to the videophone apparatus 120 may be negotiated by the system server 130. Based on the negotiation, the system server 130 may instruct the videophone apparatus 120 of which client application in the apparatus 120 to use to establish the peer to peer connection for a video call between the videophone apparatus 120 and the peer 160.
In an embodiment, accounts for video call services provided by service providers 132 may be generated automatically by the system server 130. The system server may use the authentication information (in part or as a whole) of the videophone apparatus 120 for account creation to services provided by the service providers 132. The system server 130 negotiates with the service provider 132 to generate credentials for the service provided by the service provider 132. The credentials may comprise a username and a password required to access the service of the service provider 132. For example, the username generated for the service of the service provider 132 may be based on a combination of IMSI (from 120) combined with a two-letter prefix [e.g. TW442937004711205] (to comply with the service provider 132 alphanumeric username criteria, for example), whereas both the password and the name may be generated by an algorithm on the system server 130. The credentials may be maintained at the system server 130. Furthermore, the system server 130 may carry out contact search queries and contact authentication between the system server 130 and the service provider 132. The contact search queries enable importing of peer contact information to a contact list for the videophone apparatus 120. The system server 130 may fetch contact information for the videophone apparatus 120 from various service providers 132 and peers 160, for example.
In an embodiment, a peer to peer video call connection may be enabled by one of a multitude of client applications that are components of a videophone apparatus 120 application. Third party account credentials (usernames, passwords, etc.) may be hosted by the system server 130 and utilized when needed for video call setup (calling or answering), for example.
In an embodiment, a service web application may be used for configuration of a system. The service web application may be run on any control apparatus 170 connected to a public data network, such as internet 150, for example. The control apparatus 170 may also be connected locally to the videophone apparatus 120 over a local connection 171 and utilize the network connections 122, 124 of the videophone apparatus 120 for configuration purposes. The service web application of the control apparatus 170 may provide searching/adding contacts, personalizing screen name, Wi-Fi Setup and apparatus 120 configurations, for example. The service web application of the control apparatus 170 may be a general configuration tool for tasks being too complex to be performed on the user interface of the videophone apparatus 120, such as entering text, for example.
In an embodiment, a videophone call may be established as a peer-to-peer connection between the videophone apparatus 120 and the peer 160 over a second wireless connection 122, 140, 141 to the public data communication network 150, 161 and to the peer 160. The second wireless connection 122, 140, 141 may comprise for example a wireless local area network connection, such as Wi-Fi.
In an embodiment, a videophone call may be established as a peer-to-peer connection between the videophone apparatus 120 and the peer 160 over a second wireless connection 122, 140, 142 to the public data communication network 150, 161 and to the peer 160. The second wireless connection 122, 140, 142 may comprise for example a cellular network connection provided by an operator of the system server 130.
In an embodiment, a videophone call may be established as a peer-to-peer connection between the videophone apparatus 120 and the peer 160 over a data connection 124 to the public data communication network 150, 161 and to the peer 160. The data connection 124 may comprise for example a wired local area network connection.
In an embodiment, the videophone apparatus 120 may be connected over a local connection 171 to a control apparatus 170, such as a tablet, a laptop, a remote controller, a PDA or a mobile phone, for example. The local connection may be a wireless connection and comprise Infrared, BluetoothTM, Radio Frequency Identification (RF-ID), local area network (LAN), wireless local area network (WLAN) or near field communication (NFC), for example. The control apparatus 170 may be used for remotely controlling the videophone apparatus 120, the system server 130, or the services relating to the system 100.
In an embodiment, the videophone apparatus 120 may be connected over a local data connection 124 to a network 150, such as Internet, and furthermore over a data connection 172 to the control apparatus 170 and over a data connection 151 to a system server apparatus 130, 131.
In an embodiment, the videophone apparatus 120 may be connected to the control apparatus 170 over a local connection 171 that may be a wireless connection and comprise Infrared, BluetoothTM, Radio Frequency Identification (RF-ID), wireless local area network (WLAN) or near field communication (NFC), for example.
The control apparatus 170 may be used for remotely controlling the videophone apparatus 120. The videophone apparatus 120 may be used primarily for consumption of media, whilst any configuration tasks (e.g. text entry for adding a friend to a contacts list) are performed elsewhere using existing tools with an appropriate affordance. In an embodiment, a web application utilizing the control apparatus 170 and a browser of the control apparatus 170 may be used to configure the videophone apparatus 120. The control apparatus 170 may be authenticated and configuration data sent from the control apparatus 170 to the system server 130, 131 wherein configuration settings for the videophone apparatus 120 are modified based on the received data. In an embodiment, the modified settings may then be sent to the videophone apparatus 120 over the network 150 and the local connection 124 or the wireless operator 141, 140, 122. For example, a SMS-based configuration message may be used to convey the configuration data.
In an embodiment, the web application utilizing the control apparatus 170 and a browser of the control apparatus 170 may use the data connection 172 thus making it remote and eliminating any need for local area connection 171.
In an embodiment, local (proximate) remote controls may use a direct local connection 171 (with IR, for example).
In an embodiment, the control apparatus 170 may comprise both data connection 172 and local connection 171 or only one of them. Different types of control apparatuses may also exist depending on their nature and available connections. One for configuration over data connection 172 and another for direct manipulation over local connection 171, where each has different constraints in terms of distance from the videophone apparatus 120, the types of applications they run (browser vs. bespoke app), latency, etc.
In an embodiment, other services and service providers than videophone service may be used. In such cases, service account creation process may be automatic for third party services as well. The service account created (e.g. for the videophone service) to the system server 130, 131 may be used to create further accounts for each service the user may choose. Such account creation may be done machine-to-machine between the system server 130, 131 and any third party, such as the service provider server 132. Thus, the system server 130, 131 may host all account credentials on behalf of the user or the group of users (e.g. a family, clubs or associated group of professionals in an office).
In an embodiment, configuration information between the videophone apparatus 120 and the system server 130 may be transceived via the first wireless connection and a peer-to-peer connection may be established between the videophone apparatus and the peer over a second wireless connection. The first connection for configuration information may be transmitted over cellular data connection (e.g. 3G or 4G) and the second connection for peer-to-peer content may be transmitted over non-cellular data connection (e.g. wireless LAN). However, the first or the second connection may be used for both purposes.
In an embodiment, the videophone apparatus 120 may comprise an A/V input apparatus.
FIG. 2 presents an example block diagram of a videophone apparatus 120 in which various aspects of the disclosed embodiments may be applied. The videophone apparatus 120 may be a user equipment (UE), user device or apparatus, such as a mobile terminal, or other communication device comprising a communication interface, a camera and a microphone.
In an embodiment, the videophone apparatus 120 may also be a dongle apparatus 120, as described earlier in this application. In such embodiment, a camera, a microphone and a smart application of an A/V apparatus, such as a television may be used together with the dongle apparatus 120. In such embodiment, the dongle apparatus 120 may only be required to provide a TCP/IP connection via a wireless network (e.g. 3G/4G/WLAN) to the system server. The apparatus 120 may function as a “key”, and may be similar to a 3G USB modem, for example. Such dongle apparatus 120 may provide a service-dedicated communication interface for configuration, primary content delivery and/or metrics/admin. Furthermore, such apparatus 120 may provide IMEI/IMSI credentials that are system/operator owned.
The general structure of the videophone apparatus 120 comprises a user input device 240, a communication interface 250, a microphone 270, a camera 260, a processor 210, and a memory 220 coupled to the processor 210. The videophone apparatus 120 further comprises software 230 stored in the memory 220 and operable to be loaded into and executed in the processor 210. The software 230 may comprise one or more software modules and can be in the form of a computer program product. The videophone apparatus 120 may further comprise a universal integrated circuit card (UICC) 280.
In an embodiment, the videophone apparatus 120 may comprise a display 295 for presenting information to a user of the apparatus 120. In case the apparatus 120 does not comprise the display 295, an external A/V apparatus 110 may be used for presenting information.
The processor 210 may be, e.g., a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a graphics processing unit, or the like. FIG. 2 shows one processor 210, but the videophone apparatus 120 may comprise a plurality of processors.
The memory 220 may be for example a non-volatile or a volatile memory, such as a read-only memory (ROM), a programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), a random-access memory (RAM), a flash memory, a data disk, an optical storage, a magnetic storage, a smart card, or the like. The videophone apparatus 120 may comprise a plurality of memories. The memory 220 may be constructed as a part of the videophone apparatus 120 or it may be inserted into a slot, port, or the like of the videophone apparatus 120 by a user. The memory 220 may serve the sole purpose of storing data, or it may be constructed as a part of an apparatus serving other purposes, such as processing data. Client application data for different services provided by service providers may be stored and run in the memory 220 as well as other apparatus 120 application data.
The user input device 240 may comprise circuitry for receiving input from a user of the videophone apparatus 120, e.g., via a keyboard, a touch-screen of the videophone apparatus 120, speech recognition circuitry, gesture recognition circuitry or an accessory device, such as a headset or a remote controller, for example.
The camera 260 may be a still image camera or a video stream camera, capable for creating multimedia data for videophone service.
The speaker 290 is configured to notify a user of an incoming call and to provide other user alarm sounds. Such speaker is advantageous especially in case the A/V output apparatus 110 (e.g. TV) is in off/standby mode. The speaker 290 also allows the user to answer the incoming call and hear the caller before turning the A/V output apparatus 110 (e.g. TV) on. Thus, the user may start the conversation while searching for a remote control of the A/V output apparatus 110 (e.g. TV), for example.
The microphone 270 is configured to capture user speech information for the video call service.
In an embodiment, the microphone 270 may be used to disable the speaker 290 when identical audio output is detected, using the microphone 270, from an external source, such as the A/V output apparatus 110.
