Local network connecting system local network connecting method and mobile terminal
First Claim
1. A local network connecting system comprising:
- a first local network comprising a first server assigned with a first local address;
a second local network comprising a second server;
a mobile terminal; and
a gateway connected to said first local network, wherein said mobile terminal assigns a second local address unused over a VPN “
Virtual Private Network”
to a destination address of a packet, transmits said packet to said gateway, wherein said VPN is established between said mobile terminal and said second server through said first local network, and said gateway translates said second local address into said first local address as said destination address of said packet, and transmits said packet to said first server based on said translated destination address.

Abstract
A local network connecting system includes a first local network, a second local network, a mobile terminal. The first local network is connected with a gateway and a first server assigned with a first local address. The second local network is connected with a second server. The mobile terminal VPN “Virtual Private Network”-connect to the second server through the first local network. The gateway provide mapping of local address for a terminal connected to the first local network. When a packet is sent to the first server from mobile terminal, the mobile terminal assigns a second local address unused over the VPN-connection to a destination address of the packet instead of the first local address, and transmits the packet to the gateway. The gateway translate the second local address into the first local address as destination address of the packet, and transmits the packet to the first server based on the translated destination.

7. A mobile terminal comprising:
-
an address table database;
a transmission and reception processor; and
a transmission and reception unit, wherein said address table database stores an address table describing a relation of a first local address using over a first local network and a second local address unused over VPN “
Virtual Private Network”
connected to a second local network through said first network,said transmission and reception processor assigns said second local address to a destination address of a packet based on said address table, and said transmission and reception unit transmits said packet to said first server via a gateway, that translates said second local address into said first local address as a destination address of said packet, in said first local network. - View Dependent Claims (8, 9)

10. A gateway connected to a first local network which is a route of VPN “
- Virtual Private Network”
established between a mobile terminal and a second local terminal, wherein said gateway comprising;
an address table list database;
a mapping section; and
a transmission and reception unit, wherein said address table list database stores an address table list describing a relation of said first local address using over said first local network and said second local address unused over said VPN, a mapping section translates said second local address into said first local address as destination address in a packet received from said mobile terminal based on said address table list, and said transmission and reception unit transmits said packet to the first server based on said translated destination address. - View Dependent Claims (11)

12. A method of connecting a mobile terminal to a local network, comprising:
-
transmitting a packet destined to a first server from a mobile terminal to a gateway, wherein said gateway is provided for a second local network, said first server is provided for a first local network, assigned with a first local address, and said packet has a second address unused over VPN “
Virtual Private Network”
established between said mobile terminal and said gateway through said first local network;
said gateway translating said second local address into said first local address as destination address of said packet; and
transmitting said packet from said gateway to said first server based on said translated destination address. - View Dependent Claims (13, 14)

being through said first local network;
generating an address table list describing a relation of said second local address and said first local address;
transmitting said address table to a portal gateway in said first local network;
transmitting a packet destined to said first server, wherein said transmitting a packet comprising;
assigning said second local address to a destination address of a packet; and
transmitting said packet to said first server via a gateway that translates said second local address into said first local address as a destination address of said packet in said first local network. - View Dependent Claims (16)
