FIELD OF THE INVENTION
Certain embodiments of the invention relate to broadband gateways. More specifically, certain embodiments of the invention relate to a method and system for porting gateway functionality associated with a user from a first gateway to one or more other gateways.
BACKGROUND OF THE INVENTION
With the continuous growth of digital television or broadcast multimedia, and/or broadband access, which may be used in conjunction with online businesses, social networks, and/or other online services and applications, users may desire having access to a larger number of providers and/or a broader range of content in a manner that is flexible and/or suits the users' lifestyles. Most users connect to the Internet using web browsers running on personal computers (PCs). Furthermore, most households may have one or more televisions that may be used to view television and/or multimedia broadcasts. Television broadcasts may include terrestrial TV, Cable-Television (CATV), satellite TV and/or Internet Protocol television (IPTV) based broadcasts. To ensure against unauthorized reception and/or use of TV and/or multimedia broadcast, service providers may require use of dedicated set-top boxes (STBs) that may be used to encrypt broadcast signals communicated from the service providers to generate suitable video and/or audio streams that may be played via televisions and/or other display/playback devices in the household. Furthermore, STBs and/or TVs may support Internet access. Thus, rather than using a computer to access the Internet, a user may find it more convenient to use the flat screen televisions and/or monitors in homes for the same purpose. To do so, for example, an STB connected to a flat screen television may be provided with web browsing software and protocols, and Internet connectivity, which may enable the user to easily access the Internet or check their electronic mail (email), for example, from a convenient and comfortable location such as their living room.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

In this regard, the at least one physical layer connection may comprise a plurality of physical layer connections and the at least one corresponding network access service provider may comprise a plurality of access service providers. Each of the plurality of physical layer connections may correspond to a respective one of the plurality of access service providers. In various exemplary embodiments of the invention, a home gateway may be operable to negotiate with one or more other visited gateways, a common authorized service area or domain (ASD) for providing one or more services from the home gateway to the visited gateways. The home gateway may establish one or more corresponding communication links or connections to the visited gateways based on the negotiated common ASD. The home gateway may communicate corresponding content for the services to the visited gateways via the established corresponding communication links. The negotiated common ASD may comprise information such as security features. The home gateway may communicate information about gateway functionalities required for the services to the visited gateways. The home gateway may forward or push a portion of the gateway functionalities required for the services to the visited gateways. The visited gateways may port the forwarded gateway functionalities or may perform gateway functionality conversion to support the services, which may be acquired from corresponding networks by the home gateway and/or the visited gateways.
FIG. 1 is a block diagram illustrating an exemplary communication system that comprises a home network serviced by a broadband gateway, in accordance with an embodiment of the invention. Referring to FIG. 1, there is shown a home network 100a, a plurality of distribution networks 110, a plurality of service providers 120, and a plurality of content providers 130. The home network 100a may be serviced by a broadband gateway 102a. Also shown in FIG. 1 are additional home networks 100b, . . . , 100n. Each of the home networks 100b, . . . , 100n may also be serviced by a broadband gateway 102b, . . . , a broadband gateway 102n.

For example, the Internet 110a may enable connectivity among a plurality of private and public, academic, business, and/or government nodes and/or networks. The physical connectivity may be provided in the Internet 110a via, for example, the Public Switched Telephone Network (PSTN), copper wires, fiber-optic cables, wireless interfaces, and/or other protocols and/or standards-based interfaces. The transport functionality may be performed in the Internet 110a based on, for example, one or more protocols, such as the Transmission Control Protocol/IP (TCP/IP), for example. The CATV network 110b may comprise suitable distribution nodes, systems, and/or subnetworks that may enable forwarding of communication between CATV providers and a plurality of cable-TV consumers. For example, the CATV network 110b may comprise a network of fiber optics and/or coaxial cables for use in CATV broadcasts. The satellite TV network 110c may comprise suitable distribution nodes, systems, and/or subnetworks that may enable communication of satellite TV broadcast by satellite TV providers to a plurality of consumers. For example, the satellite network 110c may comprise a plurality of orbiting satellite nodes and/or one or more terrestrial centers in a satellite-TV system.
The LAN/WAN network 110d may comprise suitable logic, circuitry, interfaces, and/or code that may be operable to enable implementation of one or more wired and/or wireless LAN or WAN standards and/or protocols. Exemplary WAN technologies comprise, for example, WiMAX-based networks. Exemplary LAN technologies may comprise, for example, those based on IEEE 802.11 standards, including, for example, WiFi-based networks. The cellular network 110e may comprise suitable logic, circuitry, interfaces and/or code that may be operable to enable communication via one or more cellular technologies. Exemplary cellular technologies may comprise Code Division Multiple Access (CDMA), wideband CDMA (WCDMA), CDMA1000, High-Speed Downlink Packet Access (HSDPA), Global System for Mobile Communications (GSM), General Packet Radio Services (GPRS), Enhanced Data Rates for Global Evolution (EDGE), and/or Universal Mobile Telecommunication System (UMTS). The cellular network 110e may comprise, for example, a plurality of control and/or switching nodes, and a plurality of base stations that enable transmission and/or reception of cellular based communications between the cellular network 110e and cellular capable devices.
The home network 100a may correspond to a location that may comprise a plurality of devices 104 which may be serviced and/or managed by the broadband gateway 102a. In this regard, the location may be a residence (e.g., home, apartment), a small business, a school, a library, and/or other like settings in which users may want to obtain access to service and/or to content provider networks. The broadband gateway 102a may be utilized in the home network 100a to provide connectivity between the home network 100a and the service providers 120 (and/or the content providers 130) via the distribution networks 110.
A broadband gateway such as the broadband gateway 102a may comprise suitable logic, circuitry, interfaces, and/or code that may be operable to provide connectivity between one or more devices in a home network, such as the home network 100a, and a plurality of external networks. For example, the broadband gateway 102a may handle a plurality of broadband physical layer connections 108 to the distribution networks 110. The broadband physical layer connections 108 may comprise wired, optical, and/or wireless connections between the broadband gateway 102 and the distribution networks 110, which may enable communication between the broadband gateway 102a and the service providers 120. The broadband gateway 102a may operate as an interface device that may allow one or more service and/or content providers to interact with various devices in the home network. In this regard, the broadband gateway 102a may be operable to perform and/or provide various services that may pertain to enabling and/or facilitating reception of content from one or more content providers, wherein the content may be delivered through one or more services providers. For example, the broadband gateway 102a may be operable to perform such operations as network access related processing (e.g., PHY/MAC, transport layer processing), encryption and/or decryption, user and/or account authentication, and/or at least some of video and/or audio processing operations that may be needed for consumption of multimedia content. The broadband gateway 102a may communicate with various devices in the home network 100, using wired and/or wireless communication links.
A single broadband gateway such as the broadband gateway 102a may be operable to handle multiple physical layer (i.e., layer 1 of the open-systems interconnection model (OSI)) connections 108 to multiple ones, or portions; of the distribution networks 110, where different ones or portions of the distribution network(s) 110 are owned, operated, leased, or otherwise associated with different network access service providers 120. For example, a first network access service provider 120 may provide network access to the broadband gateway 102a via a DSL connection over twisted-pair cabling, and a second network access service provider 120 may provide network access to the broadband gateway 102a via a cable television connection over coaxial cabling. In some instances, the broadband gateway 102a may be operable to concurrently communicate over multiple physical layer connections provided by multiple network access service providers.
The broadband gateway 102a may also be operable to provide and/or support various other, non-content related services in the home network 100a. For example, the broadband gateway 102a may be operable to provide energy management in the home network 100a, by controlling and/or adjusting configuration of one or more devices in the home network to reduce power consumption for example.
Devices serviced by, and/or connected with the broadband gateway 100a may comprise content consuming devices and/or other, non-content consuming household or home devices that may be operable to interact with the broadband gateway 102a. For example, the broadband gateway 102a may service, and/or may communicate with a plurality of home devices 104a-104j in the home network 100a. The home devices may comprise, for example, one or more of a television 104a, a laptop computer 104b, a smoke detector, a carbon monoxide detector, and/or a security alarm 104c, a computer and/or server 104d, a mobile phone 104e, a speaker 104f, an AM/FM radio 104g, a phone 104h, an appliance 104i (e.g., refrigerator), and a digital video recorder (DVR) or personal video recorder (PVR) 104j. The broadband gateway 102a may interact with each of the home devices 104a-104j via links 106a-106j, which may be supported by the broadband gateway 102a and the corresponding home device. For example, the link 106a between the broadband gateway 102a and the television 104a may comprise a High-Definition Multimedia Interface (HDMI) cable and/or 60 GHz WiGig wireless connection/interface. The link 106b may comprise, for example, a wired Ethernet link, a wireless Ethernet link, a Universal Serial Bus (USB) link, or an IEEE 1394 link. The link 106c may comprise, for example, a two-wire link or a wireless link. The link 106d may comprise, for example, a wired Ethernet link, a wireless Ethernet link, a USB link, or an IEEE 1394 link. The link 106e may comprise, for example, a wireless Ethernet link, a USB link, or a cellular link. The link 106f may comprise speaker wire and/or a wireless link. The link 106g may comprise, for example, AM and/or FM radio transmissions broadcast received using the broadband gateway 102a. The link 106h may comprise, for example, a phone line. The link 106i may comprise, for example, a wired or wireless Ethernet link. The link 106j may comprise, for example, a wired or a wireless link.
The broadband gateway 102a may provide a set of gateway functionalities enabling users or devices to access content for services found in one or more service domains ported or opened on the broadband gateway 102a. The gateway functionalities may comprise service domain types, service provider preferences, security features, remote access, content or message processing capabilities such as, for example, queue management, message routing, filtering and/or editing, software platforms, protocols, applications and/or interfaces. Depending on gateway capabilities, various gateway functionalities may be integrated into the broadband gateway 102a to secure content distribution and/or enhance user service experiences. For example, remote access gateway functionality may allow a roaming user or device to remotely access content for services provided by service providers and/or networks via its own home gateway. A home gateway for a device is a gateway where the device was assigned by networks at sign-up and where the subscriber information associated with the device is stored.
The service providers 120 and/or the plurality of distribution networks 110 may provide communication services in different coverage areas, which are referred to as service domains. Service domains or service coverage areas may be associated with corresponding service domain types. Service domain types may indicate information about communication and/or networking technologies adopted in corresponding service domains. For example, service domain types may comprise access network types such as GSM, UMTS, Wireless LAN and/or Bluetooth. Each service domain or service coverage area may implement its own security features such as, for example, authentication mechanisms, security policies and/or message integration check. In some instances, the service providers 120 and/or the distribution networks 110 may apply conditional access and/or content rights management to service reception within a specific service coverage area based on authentication and/or authorization. For example, the service providers may utilize data encryption standard (DES) encryption-based conditional access (CA) to securely deliver content to users or devices within the specific service coverage area. The specific service coverage area or service domain may be referred to as an authorized service coverage area (ASCA) or an authorized service domain (ASD). In this regard, the service reception within an ASCA or ASD may be fully controlled and protected by the service providers 120 and/or the distribution networks 110. An ASD or ASCA may comprise a set of services and associated system features with some pre-specified verifiable rules, for example, restricted services such as carrier grade video service and VoIP with QoS, allowed content types such as H.264 video, MPEG-2 video and AAC audio, and protection mechanism/profiles for device, network, and/or content, which may comprise Content encryption, I/O and memory protection, device authentication and/or network authentication.
In the exemplary embodiment of the invention illustrated in FIG. 1, although the devices 104a-104j may communicate only the broadband gateway 102 as shown, the invention may not be so limited. Accordingly, the devices 104a-104j may communicate with multiple broadband gateways in a local or home network without departing from the spirit and scope of various embodiments of the invention.
As illustrated in FIG. 1, a plurality of home networks 100b, . . . , 100n, may also be connected to the distribution networks 110. These home networks 100b, . . . , 100n may operate in substantially the same manner as the home network 100a. By having multiple home networks connected to the distribution networks 110, various applications, such as peer-to-peer communication and/or data aggregation operations may be possible by utilizing the broadband gateways 102a, . . . , 102n in the home networks.
In operation, in instances where a device such as the device 104e is near its home gateway such as the broadband gateway 102a in the home network 110a, the device 104e may request that content for a service found in a dedicated ASCA or ASD for the broadband gateway 102a, be delivered to it via the broadband gateway 102a. A dedicated ASD or ASCA for a gateway is referred to an ASD or ASCA specifically associated with the gateway. In this regard, the broadband gateway 102a may be operable to acquire content from the service providers or networks for the requested service in its dedicated ASD or ASCA.
In an embodiment of the invention, in instances where the device 104e roams away from its home gateway such as the broadband gateway 102a to one or more visited gateways such as the broadband gateway 102b, the device 104e may still need to access content for the requested service in the dedicated ASD or ASCA for the home gateway. In this regard, one or more gateway functionalities such as software structure interfaces and signaling protocols required to execute the requested service in the dedicated ASD or ASCA on the home gateway may be ported, forwarded, and/or otherwise communicated to the broadband gateway 102b. The broadband gateway 102b may utilize the ported gateway functionalities to process content or messages for the requested service in the dedicated ASD for the home gateway.
In an embodiment of the invention, in order to securely distribute or communicate content for the requested service in the dedicated ASD for the home gateway, a common ASD may be negotiated between the home gateway and a visited gateway. The dedicated ASD for the home gateway and the dedicated ASD for the visited gateway may be compared during the negotiation communication so as to determine the common ASD or ASCA. The common ASD may be determined by matching up the dedicated ASD or ASCA for the home gateway. The determined common ASD may be ported to the home gateway as well as on the visited gateway to secure transmitted and/or received content. Services found in the determined common ASD or ASCA may not be identical, but similar to services found in the dedicated ASD or ASCA for the home gateway. For example, in instances where the determined common ASD may implement lower security levels and/or less security policy constrains, content authorized for services in the determined common ASD may not be authorized for services in the dedicated ASD for the home gateway. In other words, content for services in the dedicated ASD for the home gateway may be accepted by the determined common ASD, but not vice versa.
In an embodiment of the invention, a link between the home gateway and the visited gateway may be established or set up to selectively communicate content acquired for services in the negotiated common ASD. In this regard, the acquired content may be securely distributed over the established link between the home gateway and the roaming gateway. A link between gateways, for example, links 109b, . . . 109n, may comprise wired, optical, and/or wireless connections between the broadband gateway 102a and the broadband gateways 102b, . . . , 102n, which may enable communication between the broadband gateway 102a and the broadband gateways 102b, . . . , 102n. 
In an embodiment of the invention, the home gateway and/or the visited gateway may be operable to acquire content for services from corresponding networks when needed. In this regard, the home gateway and/or the visited gateway may acquire services from corresponding networks based on the negotiated common ASD. Content for the acquired services may be communicated over the established link to secure content distribution.
In an embodiment of the invention, a gateway such as the home gateway may establish links with one or more visited gateways by matching up its own dedicated ASD. In some instances, the home gateway needs to access content for a specific service found in the dedicated ASD for the home gateway. Instead of acquiring the specific service from networks, the home gateway may check with the one or more linked visited gateways. In instances where content or similar content for the specific service is available at the one or more linked gateways, the home gateway may acquire content of interest from the one or more visited gateways over the corresponding established links. The home gateway may then compact or assemble the acquired content to support the intended service without going through the corresponding networks.
FIG. 2 is a diagram illustrating an exemplary broadband gateway, which may be operable to port gateway functionality associated with a user from a first gateway to one or more other gateways in a home network, in accordance with an embodiment of the invention. Referring to FIG. 2, the broadband gateway 102 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to provide connectivity between one or more networks, such as the distribution networks 110 shown in FIG. 1, for example, and one or more devices in a home network, such as the home devices 104a-104j in the home network 100a shown in FIG. 1.
A gateway such as the broadband gateway 102a may operate as an interface device that allows one or more devices in the home network to access one or more networks, and to access various services and/or content via those one or more networks. For example, the broadband gateway 102a may be utilized to enable interaction between the plurality of service providers 120 and/or the plurality of content providers 130, and the home devices 104a-104j. In some instances, the broadband gateway 102a may also communicate or interact with other gateways such as the broadband gateways 102b-102n to support seamless service deployment on one or more roaming devices. In instances where a home device such as the device 104e in the home network 110a roams away from its home gateway (the broadband gateway 102a) to one or more visited gateways such as the broadband gateway 102b, the device 104e may need to access content for a specific service found in a dedicated ASD for the home gateway. In instances where certain gateway functionalities utilized on the home gateway for the specific service are not currently supported or available on the visited gateway, the home gateway may be operable to forward information about the required gateway functionalities to the visited gateway.
