ESTABLISHING COMMUNICATION IN A PACKET DATA NETWORK

摘要

Communications are established between a source user (305) and a destination user (307). Data is transmitted between these users in packets (204) having a destination address (205) and communication data (206). A destination name is identified in a first packet and this packet is transmitted to a service control platform (301) identifying, in its communication data, a destination name. A packet is then returned from the control platform (301) to the originating source (305) identifying a real contactable address for the identified destination (307). Subsequent packets of data are generated at the source (305) for transmission to the destination (307) wherein the transmitted packets have the actual destination address, as returned from the service platform, appended thereto.
