1. In a packet communication network including terminal equipment, subscriber equipment, and a gateway having means for communicating with said subscriber equipment and another communication network, a packet communication control method comprising: providing said subscriber equipment and said gateway with means for communicating with service control equipment in which location information and service information regarding each subscriber terminal are stored; providing said gateway with means for communicating with enterprise network equipment over another communication network; allowing said terminal equipment to send a control signal to said gateway via said subscriber equipment for enabling information interchange with equipment on said packet communication network or another communication network; providing said gateway with first service control means for detecting a request for communication with said enterprise network equipment from destination-of-connection information included in said control signal received from said subscriber equipment; providing an arrangement wherein, upon detection of said request for communication with said enterprise network equipment, said gateway sends a control signal including address information of said gateway to said subscriber equipment; providing said subscriber equipment with second service control means for sending said control signal including address information of said gateway to said terminal equipment; and providing said terminal equipment with third service control means for assembling an IPv6 packet in a manner that, when said terminal equipment receives said control signal including address information of said gateway, said address information of said gateway is used in creation of IPv6 header information in order for packet data from said terminal equipment to be unexceptionally transferred through said gateway; and whereby, in transmission from said terminal equipment to said enterprise network equipment, packet data is unexceptionally transferred through said gateway.
