Problems solved by technology

[0004] IEEE 802.21 MIH has been proposed for a seamless handover between these heterogeneous networks, so that services can be continuously received when roaming in the vicinity of these heterogeneous networks, however, MIH may not be able to support all networks, and, Supported MIH modes may also vary by network, so it is necessary to provide WTRU MIH capability information (including, for example, whether a wireless network supports MIH and, if so, which mode for MIH to get support)

Embodiment

[0031] 1. A method for providing MIH information to a multimode WTRU in a wireless communication system comprising a plurality of wireless networks deployed under different wireless communication protocols, wherein a wireless network sends a message to the WTRU, and the information will include an indication of whether the wireless network supports MIH service and information about the supported MIH mode, whereby the WTRU can use this information as a basis for deriving a network Handover decision.

[0032] 2. In the method of embodiment 1, the information is broadcast.

[0033] 3. In the method of embodiment 2, the information is included in a beacon frame.

[0034] 4. In the method of embodiment 3, the information is included in a capability information field of the beacon frame.

[0035] 5. The method of any one of embodiments 1-4, the information may indicate whether the information service is delivered over an Ethernet network, whether the information service is deliver...

Abstract

A method and system for conveying media independent handover (MIH) capability information are disclosed. A wireless communication system includes a plurality of wireless networks deployed under different wireless communication protocols. A multi-mode wireless transmit / receive unit (WTRU) may perform a handover from one wireless network to another for continuous reception of services. The wireless network sends a message to the WTRU which indicates whether the wireless network supports MIH services and a supported MIH mode. The WTRU receives the message and makes a handover decision based on the message.

Description

[0001] This application is a divisional application with an application date of March 14, 2006 and an application number of 200680008061.6. technical field [0002] The present invention relates to a wireless communication system, and more particularly, the present invention relates to a method and a system for transmitting media independent handover capability information. Background technique [0003] Currently, many different types of wireless networks have been deployed to provide specific services desired by each wireless network. For example, wireless local area networks (WLANs), such as IEEE 802.xx-based networks, are High data rate services will be provided in a limited coverage area, while cellular networks, such as Universal Mobile Telecommunications System (UMTS) networks, will provide relatively large coverage areas in a very large coverage area supporting high-speed mobility. For lower media data rate services. [0004] IEEE 802.21 MIH has been proposed for a s...
