Wireless architecture in support of voice and data communications

摘要

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.

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; andrelaying 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; andsending 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; andreceiving 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.
