| 20080198804 | HANDOVER BETWEEN AN IEEE 802.16 WiBro NETWORK AND A UMTS NETWORK USING MEDIA INDEPENDENT HANDOVER FUNCTION - A wireless transmit/receive unit (WTRU) may include an IEEE 802.16 modem, a universal mobile telecommunication system (UMTS) modem and a media independent handover (MIH) entity. Software application programming interfaces provide the MIH entity with mechanisms to receive information about IEEE 802.16 and UMTS links, control IEEE 802.16 and UMTS modems for handover, discover an MIH server and IP multimedia system nodes, trigger mobile IP handover, etc. If an IEEE 802.16 link has been successfully established, the MIH entity starts an MIH session. When the IEEE 802.16 modem indicates that a connection is going to be terminated, the MIH entity activates the UMTS modem for handover. If the IEEE 802.16 modem indicates that a link parameter has crossed a threshold, the MIH entity sends IEEE 802.16 and WCDMA signal measurements to an MIH server. After receiving an MIH switch request, the MIH entity initiates handover to the UMTS network. | 08-21-2008 |
| 20090161629 | MEDIA INDEPENDENT HANDOVER FOR SMART PHONE ARCHITECTURE - 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. | 06-25-2009 |
| 20090201879 | INTEGRATION OF 802.21 MEDIA INDEPENDENT HANDOVER FUNCTIONALITY TO RADIO INTERFACE LAYER AND TELEPHONY SERVER - 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. | 08-13-2009 |
| 20090257400 | METHOD AND APPARATUS FOR HANDOVER BETWEEN A NETWORK SUPPORTING PROXY MOBILE IP AND A NETWORK SUPPORTING MOBILE IP - A method and an apparatus for supporting handover between a first network supporting proxy mobile Internet Protocol (IP) (PMIP) and a second network supporting mobile IP (MIP) are disclosed. A PMIP entity in the first network may perform home agent (HA) discovery such that the PMIP entity may select an HA that responds with a pre-determined code indicating that a binding entry for the WTRU exists in the HA. The PMIP entity may store the HA IP address in an authentication, authorization, and accounting (AAA) server. The PMIP entity may retrieve the HA IP address for the WTRU from the AAA server when the WTRU is readmitted, and perform a binding update using the HA IP address. A media independent handover (MIH) client may trigger an HA discovery to obtain an HA IP address without performing MIP registration. The MIP client may retain the HA IP address when disabled. | 10-15-2009 |
| 20090318145 | PUSH MECHANISM FOR INFORMATION SERVICES IN IEEE 802.21 MEDIA INDEPENDENT HANDOVER - A push mechanism for IEEE 802.21 media independent handover (MIH) information services (IS) is provided to push information to MIH users. Alternatively, an indication may be provided that information is available, and a pull mechanism may then be implemented to retrieve the information. | 12-24-2009 |
| 20090325581 | METHOD AND APPARATUS FOR DYNAMIC MOBILE PROFILE FUNCTIONALITY - A method and apparatus provide dynamic mobile profile functionality in a media independent handover. This may include an MIH server dynamically changing a mobile profile in an MIH client. | 12-31-2009 |
| 20100111040 | METHOD AND APPARATUS FOR FAST BREAK-BEFORE-MAKE MEDIA INDEPENDENT HANDOVER - A method and apparatus may be used to perform a Media Independent Handover. Data may be received from a source node in a source network serving a WTRU. The WTRU may transmit a first message to an intermediary node and receive a second message in response. The WTRU may establish connectivity on a target network and receive data from a target node. | 05-06-2010 |
| 20100284291 | MOBILITY MANAGEMENT WITH DOWNLINK-ONLY WIRELESS NETWORKS - A wireless transmit/receive unit (WTRU) may include a media application that receives data from a media server via a link on a downlink (DL) -only radio access network. The link on the DL-only radio access network may be handed over to a second DL-only radio access network. A mobility management server, such as a Media Independent Handover (MIH) server, may communicate with the WTRU via a second radio access network that is a bidirectional radio access network to facilitate the handover. MIH messages may include fields that relate to DL-only radio access technologies may be used to facilitate handover of a DL-only link. Further, MIH broadcast or multicast messages may be used to facilitate the handover of a DL-only link. | 11-11-2010 |
| 20100302968 | COMMUNICATION ACCESS TECHNOLOGY MANAGEMENT - A method and apparatus are disclosed for communication access technology management. A wireless transmit/receive unit (WTRU) may evaluate end-to-end connection performance by sending a connection ECHO message and receiving a connection ECHO response. The connection performance may be evaluated for a connection including multiple transmission paths, and for multiple connections. The WTRU may establish or modify a multihoming communication session with a mobility server using a plurality of connections. Each connection may be established using a different interface. | 12-02-2010 |
| 20110064050 | BROADCAST SERVICE HANDOVER - A wireless transmit/receive unit (WTRU) may receive a broadcast service via a broadcast system. The broadcast service may be handed over from the broadcast system to a second broadcast system, and the WTRU may receive the broadcast service via the second broadcast system. The WTRU and/or the broadcast system may change broadcast service configuration parameters (such as video encapsulation format, video codec, frame rate, audio codec) to receive and/or display broadcast service data received via the second broadcast system. Additionally, a WTRU may receive a broadcast service via a broadcast system that includes more than one broadcast transmission network. The broadcast service may be handed over from a first broadcast transmission network in the broadcast system to a second broadcast transmission network in the broadcast system. The WTRU may change broadcast service configuration parameters to receive and/or display broadcast service data received via the second broadcast transmission network. | 03-17-2011 |
| 20110069676 | INFORMATION SERVICE AND EVENT SERVICE MECHANISMS FOR WIRELESS COMMUNICATIONS - A WTRU includes a transceiver and a media independent handover (MIH) function (MIHF), which transmits via the transceiver a request to set information in an external device. The MIHF receives a response to the request to store the information in the network node indicating that the request to store the information in the network node was successful. | 03-24-2011 |
| 20110110286 | METHOD AND APPARATUS FOR MULTICAST MOBILITY - A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network. | 05-12-2011 |
