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 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 discloses a method to inform an attribution user server HSS to protect grouping data net gateway PDN GW address information in the system structure developing. The method comprises the steps that a moving management node learns that the PDN GW address information is not stored in the HSS, or the moving management node afresh selects the PDN GW; the moving management node informs the HSS the address information to store the address information. Though the invention, the HSS can directly gain the PDN GW address information from an MME not through a 3GPP AAA server, and a roaming interface between the PDN GW and the HSS is avoided.

The invention discloses a local gateway address updating method and device, which can solve the problem of LGW (Local Gateway) address updating under the condition that an MRN PGW (Mobile Relay Local Gateway) is re-located in an MRN (Mobile Relay) switching process. The local gateway address updating method comprises the steps that: a target host base station receives local gateway address allocation information; the target host base station judges that an IP address is allocated to a local gateway if an IP address needs to be allocated for the local gateway set in a mobile relay node according to the local gateway address allocation information; and the IP address of the local gateway is sent to a service gateway. One local gateway address updating device is positioned in the target host base station, and comprises a receiving module, an allocating module and a sending module. Another local gateway address updating device is positioned in the mobile relay node and comprises a judging module and a storing module. Another local gateway address updating device comprises a service gateway servicing for UE, and comprises a receiving module and an updating module. By adopting the method and device provided by the embodiment of the invention, the continuity of the S5 connection is ensured, and further the service continuity of a terminal is ensured.
