    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
