摘要:
A method for assigning a tracking area (TA) is disclosed. A mobility state of a wireless transmit/receive unit (WTRU) is determined and the TA is assigned based on the determined mobility state. Also disclosed is a method for accessing a closed subscriber group (CSG) TA. A CSG TA identifier is received at a WTRU and is stored. A CSG TA broadcast is received and the broadcast CSG TA is accessed if an identifier of the broadcast CSG TA matches the stored CSG TA identifier. Also disclosed is a method for changing a mobility state of a WTRU. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU is examined. The predetermined metric is evaluated to determine if the metric has crossed a threshold and the mobility state is changed based on the evaluated metric.

A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions.

The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.

In a wireless communication system, a method for commissioning and managing communication between a plurality of mesh points (MPs) comprises a first MP broadcasting a signal to a second MP to establish communication with the second MP. The second MP transmits a response signal to the first MP. The first MP authenticates the second MP and determines a master MP, and the first MP establishes the communication with the second MP.

A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.
摘要:
Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to perform a multi-radio access technology (RAT) access (MRA) operation. The apparatus may include a WTRU non-access stratum (NAS) entity to communicate with a first and second NAS entity of a first and second core network (CN). Alternatively, the first WTRU NAS entity communicates with a first NAS entity of a first CN, and a second WTRU NAS entity communicates with a second NAS entity of a second CN. The apparatus may include a radio resource control (RRC) entity which controls a first RAT connected to the first CN and a second RAT connected to the second CN. Alternatively, the apparatus includes an RRC entity which controls a first connection using a first RAT connected to the first CN and a second connection using a second RAT connected to a second CN.
摘要:
A method and apparatus are provided that allow a wireless transmit/receive unit (WTRU) to search and add one or more closed subscriber group (CSG) identities (IDs) in the WTRU white list while in connected mode. Such method and apparatus include but are not limited to WTRU autonomous search or a manual search, WTRU initiated procedures, or network initiated procedures. Additionally, methods that allow the network and/or the non-access stratum (NAS) to add CSG IDs are also described.
摘要:
A wireless transmit/receive unit is configured to receive system level information, including discontinuous reception (DRX) information, cell selection information, and RACH information. The system level information is received as defined parameters assigned to system information blocks or signaled through dedicated RRC signaling.
摘要:
A method and apparatus are described for controlling the application of Selected Internet Protocol (IP) traffic offload (SIPTO) or Local IP Access (LIPA) services for a wireless transmit/receive unit (WTRU). The SIPTO and LIPA services may be performed over packet data network (PDN) connections. A user of the WTRU may be prompted to accept or reject the usage of the SIPTO or LIPA services. The user of the WTRU may request switching from SIPTO or LIPA services to non-SIPTO or non-LIPA services.
摘要:
A method and apparatus are described for providing non-packet switched service to a target radio access technology (RAT) network. A circuit switched (CS) service notification message is received by a wireless transmit/receive unit (WTRU). If the WTRU has been allocated a valid temporary mobile subscriber identity (TMSI), a paging response message including the valid TMSI is transmitted after an inter-system change is performed from a source RAT network to a target RAT network. The CS service notification message is for terminating a CS call request. The source RAT network may be a long term evolution (LTE) network, and the target RAT network may be a third generation partnership project (3GPP) network. Alternatively, if the WTRU has not been allocated a valid TMSI, a paging response message including an international mobile subscriber identity (IMSI) that identifies the WTRU is transmitted after the inter-system change.
