Full Description:
BACKGROUND INFORMATION 
     Modern technology has provided a broad variety of devices that can be used to access information including data, media, etc., and to allow communication between people using various means. For example, service providers provide streaming and on-demand video to customers that can be viewed on a television, personal computer (PC) or cellular phone. Also, service providers provide data and other media to customers that can be accessed using a personal computer or other similar device, and such devices may also allow users to communicate using Instant Messaging (IM), email, or Voice over Internet Protocol (VoIP) technologies. In addition to standard wired telephone services and VoIP services, users can communicate wirelessly using cellular telephones via cellular and/or wireless (e.g., Wi-Fi) service providers. As such, a user may end up owning numerous different devices in order to access and utilize each of these services from one or a plurality of service providers. 
     Therefore, there is a need to enable multiple devices to efficiently and conveniently access communication services.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A preferred apparatus, method, and system for providing one or more devices each being capable of accessing and utilizing different services of one or more service providers are described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the preferred embodiments of the invention. It is apparent, however, that the preferred embodiments may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the preferred embodiments of the invention. 
       FIG. 1  is a diagram of a system  100  providing devices  101 ,  103 ,  105 , and  107  that are each capable of accessing and utilizing different services, according to an exemplary embodiment. These services can be associated with a single domain or multiple domains; moreover, such domains can correspond to one or more service providers. 
     As depicted in  FIG. 1 , a user may have a television monitor (or display)  101  that accesses video, video-on-demand, or other services from a service provider, for example, via a set-top box, cable, digital subscriber line (DSL), and/or satellite. The customer may also have a telephone or videophone  103  that receives sound and/or video using Plain Old Telephone Service (POTS) or Voice over Internet Protocol (VoIP) service. The user (customer or subscriber) may also have a desktop or laptop computer  105  that receives data, video, sound, or other information via an Internet access service via telephone lines, cellular connection, DSL, satellite connection, Wi-Fi, and/or cable lines. Also, the customer may have a cellular telephone  107  that receives data, video, sound, or other information via a cellular or Wi-Fi service. Traditionally these different devices are used for different forms and modes of communications that are accessed using different services. However, the system  100  depicted in  FIG. 1  allows each of the devices  101 ,  103 ,  105 , and  107  to access and utilize the services of the other devices, thus providing flexibility in the manner in which the various services are used. 
     In  FIG. 1 , the television monitor  101  is in communication with an access network  109  via a session border gateway at a customer edge  111 . The access network  109  is in communication with a database providing local applications, services, and content  113 . Similarly, the telephone  103  and laptop computer  105  are in communication with an access network  115  via a session border gateway at a customer edge  117 , and the access network  115  is in communication with a database providing local applications, services, and content  119 . Furthermore, the cellular telephone  107  communicates with an access network  121  via a session border gateway at a customer edge  123 , and the access network  121  is in communication with a database providing local applications, services, and content  125 . The access networks  109 ,  115 , and  121  are in communication with a network core  127  via a session border gateway at a network edge  129 , and the network core  127  is in communication with a database providing networked applications, services, and content  131 . The network core  127  has connectivity to one (or more) third party network  133  via a session border gateway at a network core edge  135 , and the third party network core  133  utilizes a database providing third party applications, services, and content  137 . 
     The system  100  includes an optimization module in a customer device that is configured to allow the device to access and utilize different services of one or more service providers, as depicted in  FIG. 2 , or in a network core that is configured to allow one or more customer devices to access and utilize different services of one or more service providers, as depicted in  FIG. 3 . Alternatively, the optimization module can be provided in the access network(s) or at some other location along the communication path between the information provider and the customer device. The optimization module allows the customer device(s) to send and receive information not only from the service provider to which the customer devices is originally intended, but also from any other service provider to which the user has access. Thus, for example, if a user has the ability to send and receive instant messaging (IM) communications using an internet access account, which would typically be accessible via a computer, the optimization module would allow the user to utilize the IM communications via the internet access account using the user&#39;s television, cellular telephone, etc. 
     Thus, the system  100  can allow a user to pickup a telephone call using a television, personal computer, etc. The system  100  will allow for the establishment of an information transmission session, and the session will adapt to whatever customer device is being used to allow the communication. The user can even switch devices during the session, and the session will adapt real-time. Either the device or the network will adapt the session to the device so that the user will perceive no difference, thus providing seamless continuity of the session in a device independent manner. The system  100  uses adjunct customer device(s) or provides capabilities (e.g., using middleware), or provides network-based mechanisms to provide communication service (transmission and reception) in a device-optimized fashion so that the user of a device can seamlessly get a multitude of services using the same device. This arrangement helps to minimize the number of terminals and interfaces one needs today for communications services at home or at work or while mobile. Product companies can utilize client-cluster based devices irrespective of whether it is used for voice, data, wireless or video communications. Service companies can utilize the signaling and media anchoring options for delivering sessions seamlessly to a multitude of devices based on user&#39;s demand, preference, proximity, etc. 
       FIGS. 2A-2C  are, respectively, a diagram of a customer device having an optimization module configured to allow the device to access and utilize different services of one or more service providers, a diagram of exemplary applications resident on the device, and a diagram of an exemplary protocol stack for the device, according to various embodiments. As seen in  FIG. 2A , a customer device  101  communicates with a session border gateway at the customer edge  111  via either a wired communication line  201  or a wireless communication  203  to transmit the information payload (e.g., media, voice, video, data, etc.), management and configuration information, and signaling and control information between the device and the network. The customer device  101  in this embodiment includes an open operating system  205 , hardware  207  (e.g., graphics, digital signal processor, video, audio, etc.), an optimization module  209 , and a plurality of application clients  211 ,  213 ,  215 ,  217 ,  219 , and  221 . In an exemplary embodiment, different instances (e.g., light-weight, heavy-weight, etc.) of the client can run on different physical devices in possession of the same customer. The various application clients can be used by the customer device  101  to process information for a wide variety of different features that the customer device might not otherwise be configured to handle. For example, the application clients, shown in  FIG. 2B , can include a linear television client (typical function of such a television/set-top box customer device), a video-on-demand client (also typical function of such a television/set-top box customer device), an email service client, real-time audio client, instant messaging client, presence service client, configuration management client, service management client, non-real-time audio client, and/or other miscellaneous services. 
     As shown in  FIG. 2C , the device  101  employs a session layer  251  that provides for such functions as a constant-rate input to the applications (i.e., cross-layer adaptive session). Transport layer  253  utilizes, e.g., a cross-layer adaptive Transmission Control Protocol/User Datagram Protocol (TCP/UDP) layer, with application-specific buffers and processing for adaptively streaming packets to and from the adjacent protocol layers. By way of example, the device  101  can also utilize an IP and logical link layer  255 ; such layer  255  can be either active or ready-to-be active state depending on the feedback of the lower and upper layers. At the physical layer  257 , the device  101  can adaptively turn ON or OFF (i.e., active state or inactive state) based on the upper layers&#39; receptively and processing capability. 
       FIG. 3  is a diagram of a network core  127  that is in communication with the session border gateway at the network edge  129  via either a wired communication line  301  or a wireless communication  303 , and the network core  127  is in communication with the session border gateway at the network core edge  135  via either a wired communication line  305  or a wireless communication  307 . The network core  127  in this embodiment includes a customer registration module  309 , a session/service control module  310 , a customer profile database  311 , a customer authentication module  313 , an optimization module  315 , a billing module  317 , and the networked applications/services/content database  131 . As will be described in detail below, the customer registration module  309  is used to register a user and determine the desired service control settings for the user and the user&#39;s customer device(s), which are then stored in the customer profile database  311 . The session/service control module  310  provides functions associated with managing communication sessions in accordance with the users&#39; profiles. The customer authentication module  313  is used to authenticate the user and customer device in order to allow access to the system and the optimization module  315 . And, the billing module  317  is used to compile and distribute billing information for transmission sessions. 
       FIG. 4  is a flowchart of a process  400  for registering a user to use the system and setting up profiles for the user service and control, according to an exemplary embodiment. In step  401 , the user begins the registration process, for example, using a customer device (e.g., telephone keypad, television remote control, computer via web using E.164 address (telephone number), IP address, URI/L, etc.) by contacting the customer registration module  309 . In step  403 , the user creates privacy and security profiles for media and signaling services used by the user, which are then stored in the customer profile database  311 . The user can create quality of service (QoS) profiles for media and signaling services used by the user in step  405 . The user can create device service profiles and specify primary, secondary, tertiary, etc. devices for certain time periods (e.g., primary device is set as IMs on television between 9 pm and 11 pm) in step  407 . In step  409 , the user can create storage profiles for the various services. In step  411 , the user can create media service profiles for voice, data, video, IM/SMS, storage, etc. services. The user can also create mobility and roaming service profiles in step  413 . In step  415 , the user can also create various billing and charging profiles for the services the user uses. And, in step  417 , the user can create service contact levels/periods for the services. Thus, the user can have control over the set-up and operation of the system. It is noted that the system can be provided with default, demographic, and/or geographic settings for the profiles if the user opts out of setting up certain segments of the profiles. Once the registration process is completed by the user, the user will be able to utilize the system, and can modify the profiles at a later date if so desired (e.g., if services are changed, added, or canceled, or if customer devices are changed, added, or deleted). 
       FIG. 5  is a flowchart of a process  500  for using a customer device to run a transmission session and bill for services used during the transmission session, according to an exemplary embodiment. In step  501 , a customer device is activated for use in a transmission session. The access network for that device performs a device recognition procedure in step  503 . In step  505 , a session set-up request from the user is received by the network core, which could indicate the customer device being used, as well as a target device that the user is attempting to contact or a target service that the user is attempting to utilize. In step  507 , the customer authentication module  313  performs a service authentication to determine whether the user and/or customer device is authorized to utilize the system. If the user and customer device are authenticated, then the transmission session is established in step  509 ; and in step  511  a connection is established between the customer device and the target device or service. Then, in step  513 , transmission of information is provided between the customer device and the target device/service using appropriate signaling for the devices in use until the session is terminated. In step  515 , upon termination of the session, billing data is collected for each customer device and/or service(s) used during the session, which can be prorated based on overall usage. And, then in step  517 , the billing data is distributed to the appropriate account(s) so that changes to the user can be collected and billed to the user on a periodic basis. 
       FIG. 6  is a flowchart of a process  600  for changing a selection of customer device being used during an ongoing transmission session, according to an exemplary embodiment. In step  601 , during an ongoing, active transmission session, the user selects the use of another customer device, for example, by activating or turning on another device, and the system receives a signal indicating this new activation/selection. In step  603 , the access network corresponding to the additional customer device performs device recognition, and in step  605  the network core performs service authorization for the use of the additional customer device. Upon positive completion of the recognition and authorization/authentication, the active information session is maintained in step  607 . In step  609 , the signaling of the transmission is adjusted to correspond to the appropriate signaling for the additional customer device, and thus the additional customer device will seamlessly be joined into the active information session. 
     The system through the use of the optimization module  315  is configured to anchor signaling for all registered endpoints through the (logically) nearest session border gateway (SBG-XX), and allocates the logical port in SBG-XX to which the state or status of the active port is fed. The optimization module  315  keeps dormant information/media for all registered endpoints through the (logically) nearest SBG-XX, and allocates logical port in SBG-XX to which the state or status of the active port is fed. The module periodically scans for the customer device being used for the service using an adjustable interval (default and pre-programmed options are supported). The optimization module  315  delivers signaling and media to the user-selected/chosen active device. The optimization module  315  performs adjustment of the format of the information, for example, signaling, media, control, etc. to suit the device being used. 
     The system  100  through the use of the optimization module  315  uses signaling to/from, device (preference and registration) ID, media access control (MAC) ID, etc. to identify the device in-use and going to be used. The optimization module  315  adjusts signals, media, etc., to suit the device (wired phone, television, laptop computer, mobile phone, etc.) in-use as well as devices that will be used. The SBG-XX supports signaling translation and adaptation function (STAF), media translation and adaptation function (MTAF), protocol translation and adaptation function (PTAF), encapsulation translation and adaptation function (ETAF), and command (for management) translation and adaptation function (CTAF). Such features and functions can be provided by one or more SBG-XX. The system  100  provides service continuity that is maintained seamlessly. 
     Thus, to reiterate the process set forth in  FIG. 5  in greater detail, the process begins when the user turns on the customer device that the user wants to use for a voice session, for example. The device, for example the telephone  103 , is recognized by the corresponding access network  115  through session border gateway at a customer edge (SBG-CE)  117 , and gets authorized via a live and stored local applications/services/content database (LAS-ASC)  119  for an information session based voice service. The user enters the address (IP, URI/L, E.164 number, etc.) of the target user (device preference may or may not exist), and the user “sends” the session setup request (priority and security of the session may or may not be requested at the time of sending the setup request). The target device and resource availability based response comes from the network allowing a session for voice service or other types of session with other recommended device 
     Assuming that a session for voice service is thereby established, a signaling state of the session is kept active in two (to and from) SBG-XX and LAS-ASC, and kept dormant in other SBG-XXs and LAS-ASCs. A real-time transport protocol (RTP) ping is exchanged between the calling customer device and the target device(s) to determine fastest (logical) media exchange path between the communicating devices. The media state of the session is kept active in two (to and from) SBG-XX and LAS-ASC, and kept dormant in other SBG-XXs and LAS-ASCs. If the user moves or selects another device for the same session, which is discussed with respect to  FIG. 6 , SBG-XXs and LAS-ASCs recognize and authorize the newly paired devices, the signaling and media anchors points enter active state from the dormant state, and the former (old) signaling and media anchors points enter dormant state. Thus, the user moves to continue the session with the other paired devices, and the media transmission over the session continues. When the calling customer device(s) terminates the session or the target (called) device terminates the session, then billing data is collected and distributed among all the SBG-XXs and LAS-ASCs traversed during the entire session, and all the states are released and cleared from all the networked and hosted elements or entities. 
     A similar process can be performed for a streaming video session, etc. 
     The processes described herein may be implemented via software, hardware (e.g., general processor, Digital Signal Processing (DSP) chip, an Application Specific Integrated Circuit (ASIC), Field Programmable Gate Arrays (FPGAs), etc.), firmware or a combination thereof. Such exemplary hardware for performing the described functions is detailed below. 
       FIG. 7  illustrates computing hardware (e.g., computer system) upon which an embodiment according to the invention can be implemented. The computer system  700  includes a bus  701  or other communication mechanism for communicating information and a processor  703  coupled to the bus  701  for processing information. The computer system  700  also includes main memory  705 , such as random access memory (RAM) or other dynamic storage device, coupled to the bus  701  for storing information and instructions to be executed by the processor  703 . Main memory  705  also can be used for storing temporary variables or other intermediate information during execution of instructions by the processor  703 . The computer system  700  may further include a read only memory (ROM)  707  or other static storage device coupled to the bus  701  for storing static information and instructions for the processor  703 . A storage device  709 , such as a magnetic disk or optical disk, is coupled to the bus  701  for persistently storing information and instructions. 
     The computer system  700  may be coupled via the bus  701  to a display  711 , such as a cathode ray tube (CRT), liquid crystal display, active matrix display, or plasma display, for displaying information to a computer user. An input device  713 , such as a keyboard including alphanumeric and other keys, is coupled to the bus  701  for communicating information and command selections to the processor  703 . Another type of user input device is a cursor control  715 , such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor  703  and for controlling cursor movement on the display  711 . 
     According to one embodiment, the processes described herein are performed by the computer system  700 , in response to the processor  703  executing an arrangement of instructions contained in main memory  705 . Such instructions can be read into main memory  705  from another computer-readable medium, such as the storage device  709 . Execution of the arrangement of instructions contained in main memory  705  causes the processor  703  to perform the process steps described herein. One or more processors in a multi-processing arrangement may also be employed to execute the instructions contained in main memory  705 . In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement the described processes. Thus, these embodiments are not limited to any specific combination of hardware circuitry and software. 
     The computer system  700  also includes a communication interface  717  coupled to bus  701 . Additionally, a session anchoring and shifting control module  722  provides anchor features (as described previously) to support seamless delivery of sessions across various devices. 
     The communication interface  717  provides a two-way data communication coupling to a network link  719  connected to a local network  721 . For example, the communication interface  717  may be a digital subscriber line (DSL) card or modem, an integrated services digital network (ISDN) card, a cable modem, a telephone modem, or any other communication interface to provide a data communication connection to a corresponding type of communication line. As another example, communication interface  717  may be a local area network (LAN) card (e.g. for Ethernet™ or an Asynchronous Transfer Model (ATM) network) to provide a data communication connection to a compatible LAN. Wireless links can also be implemented. In any such implementation, communication interface  717  sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information. Further, the communication interface  717  can include peripheral interface devices, such as a Universal Serial Bus (USB) interface, a PCMCIA (Personal Computer Memory Card International Association) interface, etc. Although a single communication interface  717  is depicted in  FIG. 7 , multiple communication interfaces can also be employed. 
     The network link  719  typically provides data communication through one or more networks to other data devices. For example, the network link  719  may provide a connection through local network  721  to a host computer  723 , which has connectivity to a network  725  (e.g. a wide area network (WAN) or the global packet data communication network now commonly referred to as the “Internet”) or to data equipment operated by a service provider. The local network  721  and the network  725  both use electrical, electromagnetic, or optical signals to convey information and instructions. The signals through the various networks and the signals on the network link  719  and through the communication interface  717 , which communicate digital data with the computer system  700 , are exemplary forms of carrier waves bearing the information and instructions. 
     The computer system  700  can send messages and receive data, including program code, through the network(s), the network link  719 , and the communication interface  717 . In the Internet example, a server (not shown) might transmit requested code belonging to an application program for implementing an exemplary embodiment through the network  725 , the local network  721  and the communication interface  717 . The processor  703  may execute the transmitted code while being received and/or store the code in the storage device  709 , or other non-volatile storage for later execution. In this manner, the computer system  700  may obtain application code in the form of a carrier wave. 
     The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to the processor  703  for execution. Such a medium may take many forms, including but not limited to non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as the storage device  709 . Volatile media include dynamic memory, such as main memory  705 . Transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise the bus  701 . Transmission media can also take the form of acoustic, optical, or electromagnetic waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, CDRW, DVD, any other optical medium, punch cards, paper tape, optical mark sheets, any other physical medium with patterns of holes or other optically recognizable indicia, a RAM, a PROM, and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read. 
     Various forms of computer-readable media may be involved in providing instructions to a processor for execution. For example, the instructions for carrying out at least part of the embodiments may initially be borne on a magnetic disk of a remote computer. In such a scenario, the remote computer loads the instructions into main memory and sends the instructions over a telephone line using a modem. A modem of a local computer system receives the data on the telephone line and uses an infrared transmitter to convert the data to an infrared signal and transmit the infrared signal to a portable computing device, such as a personal digital assistant (PDA) or a laptop. An infrared detector on the portable computing device receives the information and instructions borne by the infrared signal and places the data on a bus. The bus conveys the data to main memory, from which a processor retrieves and executes the instructions. The instructions received by main memory can optionally be stored on storage device either before or after execution by processor. 
     While certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the invention is not limited to such embodiments, but rather to the broader scope of the presented claims and various obvious modifications and equivalent arrangements.
