Abstract
Methods and apparatuses for redirecting a wireless transmit/receive unit (WTRU) to a dedicated core network (CN) node are described. An apparatus is configured to initiate a Service Request with a non-dedicated network node. The apparatus is configured to receive a special identifier in response to the Service Request, which indicates the apparatus should be redirected to a dedicated CN node based on subscription information. Radio access network resources associated with the apparatus may be released and the apparatus may then perform a tracking area update (TAU) request which is then forwarded to the dedicated CN node.
