METHOD AND APPARATUS FOR BROADCASTING SUPPORT OF SELECTED INTERNET PROTOCOL TRAFFIC OFFLOAD

摘要

A method and apparatus of performing selective internet protocol (IP) selective offload (SIPTO) or local IP access (LIPA) are disclosed. A wireless transmit receive unit (WTRU) receives a broadcast message from a Node-B. Then the WTRU receives a message from the Node-B that SIPTO service, or LIPA service is available for that WTRU. The WTRU then communicates using the SIPTO or LIPA service. A method and apparatus for receiving a paging message for SIPTO or LIPA services are also disclosed. The paging message includes an indicator that indicates that the message is for SIPTO or LIPA communications. The indicator may be a temporary mobile subscriber identity (TMSI) assigned by the network specifically for SITPO or LIPA communications. The indicator may also be a single bit designated to indicate that a paging message is a for SIPTO or LIPA traffic.
