Abstract: The address translation capabilities of packet-switched mobile networks are exploited to achieve bidirectional LAN communications therethrough. A multi-dash user VPN can be provided by encapsulating a multi-user LAN communication protocol for traversal of a packet-switched network. By encapsulating a commonly available multi-user LAN communication protocol, for example ethernet, remote LAN connectivity can be extended without requiring any host reconfiguration.

Abstract: The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from the communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression soft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.

Abstract: Information about virtual private networks—VPNs—in each domain of a multi-domain communications system is provided. By comparing a request for a configuration of a VPN with the provided information of other connected domains, a match can be found. VPN configuration can then be performed based on the outcome of the match. The provided domain VPN information is in one embodiment spread to other domains under constrictions put by SLAs between domain operators. The spreading of VPN information can be performed regularly or triggered by an external event. In another embodiment, the VPN configuration request is instead spread to different domains.

Abstract: Un método para transmitir información desde una primera estación de comunicaciones a una segunda estación de comunicaciones, que comprende: el ensamblaje de paquetes en la primera estación que incluye información de cabeceras e información de carga útil, y el envío de los paquetes ensamblados desde la primera estación a la segunda estación; incluyendo dicho paso de ensamblaje el ensamblaje por la primera estación de un paquete de actualización, incluyendo la sustitución de al menos parte de la información de carga útil (111) con información de actualización de la cabecera, que ha de ser utilizada por la segunda estación para interpretar la información de cabeceras en paquetes subsiguientes enviados desde la primera estación hasta la segunda estación; y incluyendo dicho paso de envío el envío de dicho paquete de actualización desde la primera estación a la segunda estación.

Abstract: The present invention deals with the problem with packet based services consuming considerable bandwidth over links with shortage of bandwidth. The object of the present invention is to reduce the amount of information when transferring a signalling message and thus save bandwidth. After receiving a signalling message in a first node the signalling message is identified. The signalling message is replaced by an indicator, under usage of informati on from the identification, which indicator is transferred to a second node. The second node restores the signalling message using the indicator.

Abstract: A telecommunications system (200), base station system (250) and method are provided that are capable of effectively distributing a multicast signal to at least one of a plurality of base transceiver stations (280). More specifically, the base station system (250) includes a plurality of base transceiver stations (280), a radio network server (270), an Internet Protocol gateway (260), and Internet Protocol network (290). The Internet Protocol network (290) includes a plurality of routers (292) which are capable of utilizing a multicast address within a signal to direct the call towards one of the base transceiver stations (280) and is also capable of utilizing the multicast address within the signal to make and direct a copy of the signal towards another one of the base transceiver stations (280).

Abstract: The present invention relates generally to configuration of routers in a communication WAN and more particularly with the problems of substantial wor k with manual configuration of routers in a WAN and the need for automation of the configuration process. A new node is added to an existing router within an Intranetwork. The node is to be configured to act like a router. A physical connection and a Point to Point link are established between the existing router and the new node. A routing protocol is started to make it possible f or the new node to send and retrieve IP traffic. The new node finds automatical ly the essential resources to receive configuration information. By means of th e configuration information, the new node is automatically configured.

Abstract: A circuit emulation method with garbage removal is used to convert a circuit-switched network for packet-switched transmissions while reusing as much of the existing circuit-switched infrastructure as possible. The garbage removal function removes unnecessary information from a packet before it can be transported, which increases the transport efficiency and decreases the transport delay.
