Abstract: A first media independent handover function (MIHF) receives a media independent handover (MIH) capabilities discovery request from a second MIHF and generates a MIH capabilities discovery response message, including one or more parameters. Then the first MIHF sends the MIH capabilities discovery response to the second MIHF. Based on the information contained in the MIH capabilities discovery response, the first MIHF may receive a handover request message from the second MIHF. The one or more parameters included within the discovery response message indicates the specific technologies for which the first MIHF supports a MMB handover. The one or more parameters may include a list of the technologies for which a make-before-break (MMB) handover is supported. For example, a parameter may use a specific bit structure wherein each bit is a Boolean representation of whether MMB handover is supported for a specific type of technology.

Abstract: The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.

Abstract: A measurement report request message (350) is sent to a measurement terminal (314) in the wireless local area network (WLAN). A measurement report response message sent from the measurement terminal is evaluated by the media access control (MAC) function (334) to determine whether a handover condition exists. A media independent handover (MIH) trigger is generated by the MAC function if the handover condition exists. The MIH trigger is sent to MIH function (340). The MIH and MAC functions are located in the same network node. Independent claims are included for the following: (1) apparatus for generating MIH trigger; and (2) communication frame for providing MIH information.

Abstract: Ciphering control and synchronization for both U-plane data and C-plane signaling messages in a wireless communication network are disclosed. Ciphering entities are located in a wireless transmit/receive unit (WTRU) and a network. The ciphering entities of the WTRU and the network perform ciphering control and ciphering parameter synchronization. The ciphering may be performed with a packet data convergence protocol (PDCP) layer sequence number (SN) for user plane data, a non-access stratum SN, a radio resource control SN, or an encryption SN for a control plane message. Alternatively, the ciphering control and ciphering parameter synchronization may be performed by PDCP entities of the WTRU and the network. For ciphering parameter synchronization, HFN and SN synchronization and counter check procedures are performed by the WTRU and the network based on a synchronization command message, sequence number window information, or a counter check message exchanged between the WTRU and the network.

Abstract: A method for generating a media independent handover (MIH) trigger in a wireless local area network begins by sending a measurement report request message (502) to a measurement entity (502) in the network. The measurement entity takes the measurements and sends a measurement report response message (522) to a medium access control (MAC) function (504). The MAC function (504) evaluates the measurements and determines whether a handover condition exists, based on the measurements. The MAC function generates a MIH trigger if the handover condition exists.
