| 摘要 |
The present invention relates to a method and an apparatus for establishing connections between tow subscribers in an Internet Protocol (IP) based network, said network being divided into zones, or subnetworks, each zone being managed by a gatekeeper (15, 15'; 25, 25'). All gatekeepers are connected to a zone management means (17; 27), which holds information about the logical addresses of all user terminals (11, 11'). A first user (11) in a first zone (13) managed by a first gatekeeper, who wishes to establish a connection to another user (11') in another zone (13') managed by a second gatekeeper (15') sends a request to the first gatekeeper (15), from which the request is forwarded to the zone management means (17). The zone management means (17) requests the address from the second gatekeeper (15') and returns an address confirmation, so that the connection may be set up. |
