Title:
WIRELESS COMMUNICATION METHOD AND APPARATUS FOR PREVENTING NETWORK ACCESS BY MOBILE STATIONS WHICH SUPPORT AN INCOMPATIBLE INTERNET PROTOCOL VERSION
Document Type and Number:
WIPO Patent Application WO2006019644
Kind Code:
A3
Abstract:
A method and apparatus for determining whether attach procedures between a wireless transmit/receive unit (WTRU) and a network should proceed based on whether the internet protocol (IP) version, (i.e., packet data protocol (PDP) type), of the WTRU is compatible with the network. In one embodiment, the WTRU receives a network compatibility message from the network which indicates the network's IP version. If the network's IP version is determined by the WTRU to be compatible, the WTRU and the network proceed with the attach procedures. In another embodiment, the network receives an attach request message from the WTRU which indicates the IP version of the WTRU. If the IP version of the WTRU is determined by the network to be compatible, the network and the WTRU proceed with the attach procedures. For both embodiments, another network is selected if the IP versions of the WTRU and the network are not compatible.
