A mobile routing device communicates over multiple wireless networks with a Host Network Server residing on a Local Area Network. The mobile routing device also communicates with at least one client device. The mobile routing device includes multiple router network adapters, each interfacing with one of the wireless networks to send and receive data from the wireless network. Each router network adapter having a gateway address, associated with the wireless network, that the Host Network Server uses to send data to the mobile routing device. The mobile routing device also includes at least one client router network adapter that interfaces with the at least one client device. Each client router network adapter is associated with an end point address that each Host Application uses to send data to the client device. Data is sent to the client device via the Host Network Server, via at least one of the wireless networks, and via the mobile routing device, using only the end point address. Consequently, a data sender is unaware of the wireless networks used to transport the data and the corresponding gateway addresses.

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

The invention generally concerns the issue of providing connectivity between two different address realms, generally referred to as an inside realm and an outside realm, by establishing connections through an intermediate gateway. The gateway normally has a number of outside-realm gateway addresses for enabling representation of inside-realm nodes in the outside realm. In a first aspect, support for flexible outside-realm initiated connections is enabled by dynamically establishing new gateway connection states triggered, for each new connection, by a respective user-resource identifier query initiated from a corresponding outside node. In a second aspect of the invention, intelligent use of predetermined connection information in the process of setting up new gateway connection states makes it possible to significantly increase the number of connections that can be simultaneously supported by the gateway using a limited number of outside-realm addresses.

A method and apparatus for securely establishing voice over Internet Protocol calls are disclosed. In a Registration Security approach, a Gatekeeper sends an Access Token in all Registration Request messages. The Access Token contains information that authenticates the Gateway to the Gatekeeper. The Gatekeeper formats a message to an authentication server that will authenticate the information contained in the token, and the server responds with either an Access-Accept or Access-Reject message. The Gatekeeper responds to the Gateway with either a Registration Confirm message or a Registration Reject message. If a call is then placed from a successfully authenticated Gateway, that Gateway generates a new Access Token that is identical to the one generated during registration, except for the timestamp. The Gatekeeper uses the authentication server to authenticate the originating gateway, before sending the designation side Access Confirm message. As a result, a non-authenticated endpoint that knows a Gateway's address cannot use the Gateway address to circumvent security and access the telephone network to place unauthorized calls or free calls. In Admission or Per-Call Security, a Gateway is also required to include an Access Token in all originating side Admission Request messages. Such token contains information that identifies the user of the Gateway to the Gatekeeper, based on an account number and PIN obtained from the user. The Access Token is authenticated in the manner described above.

Therefore, a phenomenon that the user access is intercepted can be effectively prevented.

A network communication method implementing the function of network load sharing and the function of redundancy backup, including WAN, LAN host and multi gateway used for connecting WAN with LAN host. The gateway includes main gateway and standby gateway. Within LAN the gateway address configured by each host is the virtual IP address of the gateway.

A communication method and apparatus using the IP address of a gateway for an MN in a VPN are provided. When the MN is to access the VPN, the gateway acting an FA in the VPN performs a Mobile IP registration on behalf of the MN and is allocated a HoA for the MN from an HA. Therefore, the number of addresses required for the Mobile IP registration of the MN is reduced and overlap between an IP-in-IP tunnel for Mobile Internet and an IPsec tunnel for the VPN is avoided. As a result, packet transmission overhead is reduced.

An inside-realm node (A) attempting to connect to an outside-realm node (B) through an intermediate gateway (30) requests central configuration from a gateway resource manager (40). In response to the configuration request initiated from the inside-realm node, an outside-realm gateway address and an inside node port number are centrally allocated to the inside-realm node by resource allocation logic (42). Establishment of the connection is initiated at least partly based on the allocated address and port number by means of appropriate signaling with the gateway (30). The allocated address and port number are signaled back to the requesting inside-realm node in a configuration reply, allowing inside-realm node to configure its communication interface accordingly. The central allocation of socket parameters for the inside-realm node is preferably performed based on predetermined connection information, which is included in or derivable, for example by means of the name-to address translator (50), form the initial configuration request.

A router is configured for sharing routing rules with other routers, the routing rules defining aggregated routes according to a prescribed topology. Each routing rule, used by the router for routing a packet having a corresponding matching destination address prefix, specifies a corresponding address prefix pattern rule for extracting an identified pattern from a portion of the destination address, and a gateway address pattern rule for generating a gateway address, for a gateway providing reachability to the destination address, based on applying the identified pattern to a specified portion of the gateway address. The router generates a routing update message that describes the address prefix pattern rule and the gateway address pattern rule, and outputs the routing update message to a second router according to a prescribed distance vector routing protocol (e.g., Multiprotocol Extension for Border Gateway Protocol).
