1. A communication system, comprising:
- a first home network having a first local gateway and a first home network gateway; and
a second home network having a second local gateway and a second home network gateway,wherein the first and second home network gateways are associated with a mobile core network,wherein the first local gateway is configured to establish a user data plane communication between a wireless transmit receive unit (WTRU) on the second home network and a device on the first home network that bypasses a packet data network egress of the mobile core network, wherein the user data plane communication is established via at least a direct tunnel between the first and second local gateways or the first local gateway and the second home network gateway such that the user data plane communication uses a backhaul through which the direct tunnel is routed to bypass the packet data network egress of the mobile core network, wherein the packet data network egress of the mobile core network bypassed comprises at least one of a general packet radio service support node (GGSN) or a packet data network gateway (P-GW) of the mobile core network, and wherein the first local gateway is configured to perform a subset of functions provided by the GGSN or the P-GW bypassed including WTRU policy based packet filtering, rate policing or shaping, WTRU IP address assignment, and direct tunneling between the first local gateway and at least one of the first and second home network gateways.

Abstract
The implementation of Local IP Access (LIPA), “Extended” LIPA (ELIPA), and Selected IP Traffic Offload (SIPTO) for the design of a “Converged Gateway” (CGW) are disclosed. The gateway system may provide various features such as femtocell access to local networks, public Internet, and private service provider networks.

1. A communication system, comprising:
-
a first home network having a first local gateway and a first home network gateway; and a second home network having a second local gateway and a second home network gateway, wherein the first and second home network gateways are associated with a mobile core network, wherein the first local gateway is configured to establish a user data plane communication between a wireless transmit receive unit (WTRU) on the second home network and a device on the first home network that bypasses a packet data network egress of the mobile core network, wherein the user data plane communication is established via at least a direct tunnel between the first and second local gateways or the first local gateway and the second home network gateway such that the user data plane communication uses a backhaul through which the direct tunnel is routed to bypass the packet data network egress of the mobile core network, wherein the packet data network egress of the mobile core network bypassed comprises at least one of a general packet radio service support node (GGSN) or a packet data network gateway (P-GW) of the mobile core network, and wherein the first local gateway is configured to perform a subset of functions provided by the GGSN or the P-GW bypassed including WTRU policy based packet filtering, rate policing or shaping, WTRU IP address assignment, and direct tunneling between the first local gateway and at least one of the first and second home network gateways. - View Dependent Claims (2, 3)

4. A method to enable communication between a wireless transmit receive unit (WTRU) on a first home network and a user device on a second home network, wherein the first home network has a first local gateway and a first home network gateway, the second home network has a second local gateway and a second home network gateway, and the first and second home network gateways are each associated with a mobile core network, the method comprising
establishing user data plane communication between a WTRU on the first home network and the user device on the second home network via at least a direct tunnel between the first and second local gateways or the first home network gateway and the second local gateway such that the user data plane communication uses a backhaul through which the direct tunnel is routed to bypasses the packet data network egress of the mobile core network, wherein the packet data network egress of the mobile core network bypassed comprises at least one of a general packet radio service support node (GGSN) or a packet data network gateway (P-GW) of the mobile core network, and wherein the first local gateway is configured to perform a subset of functions provided by the GGSN or the P-GW bypassed including WTRU policy based packet filtering, rate policing or shaping, WTRU IP address assignment, and direct tunneling between the first local gateway and at least one of the first and second home network gateways; -
receiving user data from a WTRU at a first logical interface, the user data intended for the user device on the second home network; signaling the mobile core network to indicate that data being sent is to bypass a packet data network egress of the mobile core network; and sending the user data to the user device on the second home network using the established user data plane commination via the direct tunnel through the backhaul. - View Dependent Claims (5)

6. A device to enable communication between a wireless transmit receive unit (WTRU) on a first home network and a user device on a second home network, wherein the first home network has a first local gateway and a first home network gateway, the second home network has a second local gateway and a second home network gateway, and the first and second home network gateways are each associated with a mobile core network, the device comprising:
-
a first logical interface to the WTRU, a second logical interface to the mobile core network; and a processor configured to; signal to the mobile core network via the second logical interface that user data plane communications received at the first logical interface intended for the second home network are to bypass the packet data network egress of the mobile core network, wherein the packet data network egress of the mobile core network bypassed comprises at least one of a general packet radio service support node (GGSN) or a packet data network gateway (P-GW) of the mobile core network, and wherein the device is configured to perform a subset of functions provided by the GGSN or the P-G bypassed including WTRU policy based packet filtering, rate policing or shaping, WTRU IP address assignment, and tunneling between the first local gateway and at least one of the first and second home network gateways. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
