Network system comprising multiple access network gateways interconnected via networking equipment, each of the access network gateways being adapted for connecting user equipment devices to the network system, wherein the network system comprises a database wherein private networks are defined as groups of predetermined user equipment devices, and wherein the access network gateway are configured to interconnect user equipment devices belonging to a single private network via SDN service chains to emulate the single private network inside the network system.

Network system

A method for managing network traffic between one or more user equipment devices in a private network and a server outside the private network via a private gateway, a server gateway and a connection therebetween. The server gateway acts as a router and the private gateway acts as a bridge. The method including monitoring the connection between the private gateway and the server gateway; in the event of loss of connection, switching the private gateway from a bridge operation mode to a minimal service mode; repeating the previous method steps; in case of retrieved connection, switching the private gateway from the minimal service mode back to the bridge operation mode; and repeating the previous method steps. The private gateway provides minimal routing services to allow data traffic in the private network to continue in the minimal service mode.

A Method for retrieving at least one image from a database (DB) of images based on at least two input images (image i, image j), comprises the steps of determining () first low level feature correspondences (LC) between said at least two input images (image i, image j), searching () within said database (DB) for at least two sets (Mi, Mj) of images respectively matching said at least to images (image i, image j), determining () second low level features correspondences (LC) between respective images from said at least two sets of images (Mi, Mj), determining () a first set of relationships (RLC) between entities of said at least two input images (image i, image j) based on said first low level feature correspondences (LC), determining () a second set of relationships (RLC) between respective entities of said respective images from said at least two sets of images (Mi, Mj) based on said second low level feature correspondences (LC), identifying () matching relationships between said first set of relationships (RLC) and said second set of relationships (RLC), checking () the quality of the matching relationships, and, if matching relationships of sufficient quality are found, retrieving () the at least one image corresponding to the matching relationships of said second set from said database, and providing said at least one image of said second set as output.

Method and arrangement for image retrieval based on multiple images

A method for constructing an image model (M; M) from at least one image data input (IV; IV-IVn), comprises the steps of, in an iterative way,

Method and arrangement for image model construction

An exemplary method of providing a virtual representation includes determining a plurality of position constraints that correspond to physical positions of individuals relative to each other. A plurality of determined viewing constraints each correspond to a position of one of the individuals relative to a display used by that individual for viewing the virtual representation. Relative positions of virtual representations of the individuals in the virtual representation are determined to correspond to the determined position and viewing constraints.

Method and system for providing consistency between a virtual representation and corresponding physical spaces

A Method for providing a trusted feedback () in an access network () is described, wherein a real time service monitor () for real time monitoring the quality of service provided to at least one user () by a server () via the access network () is placed in an access multiplexer () being the last part of the access network () towards the user (), wherein the real time service monitor () is sending a trusted feedback signal () from the access multiplexer () at least back to the server (), which signal () comprises real time information about the quality of service passing through the access multiplexer (), plus an access network () comprising at least one data link connecting at least one access multiplexer () being the last part of the access network () towards at least one user () with a core network or at least one server () providing a service () to the user () connected to the access network () via the access multiplexer () is described, wherein a real time service monitor () is arranged in the access multiplexer () providing real time monitoring of the quality of service passing through the access multiplexer (), wherein the real time service monitor () provides a trusted feedback signal () to the server () comprising information about the quality of service in real time, plus an access multiplexer () adapted to receive a multimedia signal () from a multimedia provider () and to forward at least part of said multimedia signal () to at least one user () is described wherein said access multiplexer () comprises a real-time service monitor () adapted to collect information about the multimedia signal () passing the access multiplexer () and being transmitted between said multimedia provider () and a particular user ().
