摘要:
A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.
摘要:
A wireless transmit/receive unit (WTRU) may include two or more modems, each configured to link to a different network, and a media independent handover (MIH) client. An application programming interfaces (API) may provide the MIH client with mechanisms to receive information about links, control the modems for handover, discover a MIH server and IP multimedia system nodes, trigger mobile IP handover, etc. If a link has been successfully established, the MIH client may start a MIH session. When the modem indicates that a connection is going to be terminated, the MIH client may activate the second modem for handover. If the first modem indicates that a link parameter has crossed a threshold, the MIH client may send signal measurements to a MIH server. After receiving a media independent handover switch request, the MIH client may initiate handover to the second network.

A multiple radio access technology (RAT) apparatus with mobility middleware provides a user with access to various RAT networks, such as a frequency division duplex (FDD) network and a wireless local area network (WLAN). In one embodiment, the apparatus is a dual mode FDD/WLAN converged wireless communication handset which includes a terminal equipment (TE) module having mobility middleware, an applications and protocols processor and a terminal interface (TI). The dual mode FDD/WLAN converged wireless communication handset further includes a user services identity module (USIM), a mobile termination (MT) module and a protocol stack which interface with the mobility middleware via a plurality of links. In another embodiment, the multi-RAT apparatus is terminal equipment which includes a mobility middleware core module, a mobility middleware communication module, a driver and an insertably removable wireless communication device for providing a multiple radio transport medium to applications running in the terminal equipment.
摘要:
A method and apparatus for managing radio resources in one or more wireless communication networks. At least one radio resource manager (RRM) is provided within a network node, or as an independent entity. The RRM monitors performance on wireless communication links of the network(s) and interacts with nodes associated with those links to change the configuration on a particular wireless communication link if its performance (i.e., quality) falls below an established threshold. Information regarding current resource usage of the network is sent to the RRM by the nodes. Each of the nodes may send a quality report to the RRM including wireless communication link quality measurements and performance statistics. Alternatively, the RRM may perform the wireless communication link quality measurements. The RRM facilitates the broadcasting of information regarding current resource usage of one network to other networks to avoid collisions and interference.
摘要:
Methods and systems providing application layer support for one or more sleeping nodes in constrained networks are contemplated. Embodiments contemplate inserting sleep information in a header option or payload of an application layer message. The application layer message may be conveyed in a hypertext transfer protocol (HTTP) or a constrained application protocol (CoAP). Embodiments contemplate communicating the application layer message to a server, which may serve as a caching and/or buffering proxy.

Method and apparatus for attaching an IMS enabled wireless transmit/receive unit (WTRU) to a long term evolution (LTE) wireless network. With one attach request, the WTRU registers and authenticates itself to the network, obtains an IP address allocation, and SIP registration.
