Wireless architecture in support of voice and data communications
First Claim
1. A method for operating a wireless access network, comprising:
- via a wireless base station,for Iu-CS voice traffic, acting as a network controller, by,terminating Iu-b signals from user equipment; and
relaying the voice traffic over Iu-CS via an IP sec tunnel; and
for data traffic, acting as the network controller, by,terminating Iu-b signals from the user equipment;
striping IP payload; and
sending the data traffic inside IPsec; and
via a wireless gateway,for Iu-CS voice traffic, acting as a security gateway, by,establishing the IP sec tunnel with the wireless base station without the support of a GPRS Tunneling Protocol (GTP) as defined over Iu-PS; and
receiving and forwarding the tunneled Iu-CS voice traffic to a mobile switching center; and
for data traffic, acting as a security gateway, by,encapsulating the IP payload and send it via Gn to GGSN.

Abstract
A wireless access network including a wireless base station configured to, for Iu-CS voice traffic, act as a network controller, by, terminating Iu-b signals from user equipment, and relaying the voice traffic over Iu-CS via an IP sec tunnel. And for data traffic, wireless base station is configured to act as the network controller, by, terminating Iu-b signals from the user equipment, striping IP payload, and sending the data traffic inside IPsec. Further, the wireless access network includes a wireless gateway configured to act as a security gateway for Iu-CS voice traffic, by, establishing the IP sec tunnel with the femtocell base station without the support of a GPRS Tunneling Protocol (GTP) as defined over Iu-PS. Also receiving and forwarding the tunneled Iu-CS voice traffic to a mobile switching center, and for data traffic, encapsulate the IP payload and send it via Gn to GGSN.

6. A radio access network, comprising:
-
a wireless gateway; and a wireless base station configured to, communicate with at least one user equipment without any modifications to support Wi-Fi at the user equipment; communicate with the wireless gateway; send IP data payloads to the wireless gateway inside a secure tunnel without encapsulation; the wireless gateway, configured to, establish the secure tunnel with the wireless base station; act as a security gateway for Iu-CS voice traffic. - View Dependent Claims (7, 8)

9. A method for data communication in wireless access network comprising,
establishing a secure tunnel IPsec between a wireless base station and a wireless security gateway; -
transmitting, via the wireless base station, Iu-CS traffic inside the tunnel to the wireless security gateway, forwarding, via the wireless security gateway, the Iu-CS traffic to a mobile switching center; and terminating, via the wireless base station, radio interface signal from user equipment; relaying payload from the radio signal over Iu-PS by, extracting an IP payload; re-encapsulating the IP payload into GTP-U; and sending the IP payload over Iu-PS via the tunnel, to the wireless gateway. - View Dependent Claims (10, 11)

12. A method of managing a radio access network, comprising:
-
transmitting at least one data payload directly over IPsec, between a femtocell base station and a wireless gateway, wherein the transmitting is without the support of GTP as defined over lu-ps; and handling control traffic in substantially the same way as data traffic via the femtocell base station. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
