Abstract:
1. A gateway for interconnecting different networks, comprising: a network access means for interconnecting a first network that provides a wireless access function to one or more mobile stations and each of distinct second networks which provide an internet access function to the mobile stations, wherein said each of the second networks includes a networking device connected to an internet; a first tunnel establishment means for establishing, in the first network, first tunnels between the gateway and a base station accessing the mobile stations via wireless communications, for transmission of different packets to the respective mobile stations, wherein the first tunnels are established in accordance with a tunneling protocol; a second tunnel establishment means for establishing second tunnels between the gateway and respective networking devices of the second networks, for packet transmission; a tunnel-mobile station connecting means for connecting the first tunnels with the mobile stations; and a tunnel-to-tunnel interworking means for interworking the first tunnels with the second tunnels, wherein the tunnel protocol is a Generic Routing Encapsulation (GRE), and wherein the second tunnels are IP-in-IP tunnels.
