METHOD AND DEVICE FOR EFFICIENT VPN SERVER INTERFACE, ADDRESS ALLOCATION AND SIGNAL TRANSMISSION WITH LOCAL ADDRESSING DOMAIN

摘要

FIELD: physics; communication.;SUBSTANCE: invention relates to communication systems and more specifically to a method and a device for efficient delegation and/or address allocation and/or transmitting signals in a virtual communication network, for example a network supporting virtual private networks (VPN) and one or more addressing domains and meant for such systems as mobile communication systems, where the number of mobile nodes in each of several visited domains can vary relatively fast, which makes delegation of static address from a personal domain in each of the visited domains inefficient. Address delegation can be done beforehand upon requests for address allocation from a visiting mobile node, or address delegation can be initiated by an address allocation request. Information update messages constantly inform the personal domain on allocation status of addresses delegated to the said personal domain and can, in particular initiate additional delegation.;EFFECT: supporting a range of unallocated delegated addresses which increases efficiency of transmitting signals.;28 cl, 19 dwg
