Embodiment

[0068] CLAIMS 1. A method for a communication device to perform Media Independent Handover (MIH).

[0069] 2. The method of embodiment 1, further comprising generating a high layer handover message.

[0070] 3. The method of embodiment 1, further comprising sending the high-level handover message encapsulated in a low-level formatted communication.

[0071] 4. The method according to any one of embodiments 2 or 3, further comprising setting a higher layer timing device with a timeout period related to the sending of the encapsulated higher layer handover message.

[0072] 5. The method of embodiment 4, further comprising retransmitting the high layer handover message encapsulated in the low level formatted communication unless a high layer acknowledgment is received before the timeout period expires.

[0073] 6. The method of embodiment 5 is performed by a wireless transmit / receive unit (WTRU), wherein the encapsulated high layer handover message is sent using User Datagram P...

Abstract

The present invention relates to a method and device for performing media independent handover (MIH) in a wireless communication system. The method includes, and the apparatus is configured to, generate a higher layer handover message, send the higher layer handover message encapsulated in a lower level formatted communication, set a higher layer timing device for a timeout period in connection with the sending of the encapsulated higher layer handover message, and resend the higher layer handover message encapsulated in a lower level formatted communication unless a higher layer acknowledgement is received before expiration of the timeout period.

Description

technical field [0001] The present invention relates to wireless communication systems. In particular, the present invention relates to methods and apparatus for media-independent messaging via the Internet, for example using transmission of IEEE 802.21 compliant media-independent handover messages via Internet Protocol (IP). Background technique [0002] Currently, the IEEE 802.21 standard group is developing a framework to exchange support messages such as 802.21 compatible information, events, and commands between the network and mobile nodes to enable seamless handover. For example, a network node called an 802.21 server can send an information element to a mobile node, which then has a list of network operators from which the mobile node can select a target network to which it will handover. However, the IEEE 802.21 standard does not specify a means for communicating such information via the Internet Protocol (IP). [0003] Certain 802.21 compliant messages carry time...
