1. A wireless communication Access Terminal for having concurrent Internet Protocol Activity with a Tethered Device, the Access Terminal comprising:
- an air interface configured to receive incoming packets, the incoming packets comprising one or more first Internet Protocol version packets and one or more second Internet Protocol version packets;
an Internet Protocol stack;
a first Internet Protocol version interface adapted in a non-bridged mode for delivering first Internet Protocol version packets to the Internet Protocol stack; and
a second Internet Protocol version interface, split from the first Internet Protocol version interface, and adapted in a bridged mode for connecting to the Tethered Device, the second Internet Protocol version interface being configured to forward second Internet Protocol version packets to the Tethered Device;
wherein the air interface is configured to determine whether each incoming packet is a first Internet Protocol version packet or a second Internet Protocol version packet, and to forward the incoming packet to the first Internet protocol version interface or the second Internet Protocol version interface, respectively, based upon this determination; and
wherein the second Internet Protocol version interface forwards second Internet Protocol version packets to the Tethered Device concurrently with the first Internet Protocol version interface forwarding first Internet Protocol version packets to the Internet Protocol stack.

Abstract
Using split interfaces for Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4), and bridging the IPv4 interface, makes it possible to support a Tethered Device (TD) and an Access Terminal (AT) having concurrent IP connectivity. This configuration enables the support of IP Multimedia Subsystem (IMS) applications in the AT using IPv6 while concurrently supporting general Internet usage on a TD. It is also possible to bridge an IPv6 interface to the TD.

9. A method for providing an access terminal concurrent Internet Protocol activity with a tethered device, comprising:
-
receiving, at an air interface, incoming packets, the incoming packets comprising one or more first Internet Protocol version packets and one or more second Internet Protocol version packets; and determining, by the air interface, whether each incoming packet is a first Internet Protocol version packet or a second Internet Protocol version packet, and to forward the incoming packet to a first Internet protocol version interface or a second Internet Protocol version interface, respectively, based upon this determination; wherein first Internet Protocol version interface is adapted in a non-bridged mode for delivering first Internet Protocol version packets to an Internet Protocol stack; wherein the second Internet Protocol version interface is split from the first Internet Protocol version interface, and is adapted in a bridged mode for connecting to the tethered device, the second Internet Protocol version interface being configured to forward second Internet Protocol version packets to the tethered device; and wherein the second Internet Protocol version interface forwards second Internet Protocol version packets to the tethered device concurrently with the first Internet Protocol version interface forwarding first Internet Protocol version packets to the Internet Protocol stack. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
