摘要： Methods and apparatuses for redirecting a wireless transmit/receive unit (WTRU) to a dedicated core network (CN) node are described. An apparatus is configured to initiate a Service Request with a non-dedicated network node. The apparatus is configured to receive a special identifier in response to the Service Request, which indicates the apparatus should be redirected to a dedicated CN node based on subscription information. Radio access network resources associated with the apparatus may be released and the apparatus may then perform a tracking area update (TAU) request which is then forwarded to the dedicated CN node.

摘要： Techniques for congestion management in a communication network are contemplated. For example, a wireless transmit receive unit (WTRU) may include a Radio Resource Control (RRC) layer and a Non-Access Stratum (NAS) layer. The RRC layer may receive an indication for a service, for example from the NAS. The indication may be interpreted as a request for the particular service indicated. For example, the indicated service may correspond to at least one of: a mobile originated (MO) voice communication, a circuit switched fallback (CSFB) supplementary service (SS), or a MO short message service (SMS). The RRC layer may receive a signal from a network indicating that one or more services provided by the network are allowed. The RRC layer may send a connection request to the network for the service sought by the NAS if that service is one of the one or more services allowed.

摘要： Location and other status information may be communicated between Proximity Service (ProSe) users. A ProSe function may retrieve a ProSe WTRU's location data from SLP and provide it to a monitoring WTRU via a ProSe discovery procedure or EPC-level ProSe discovery procedure. A ProSe function may retrieve a ProSe WTRU's location data from a ProSe WTRU and provide it to monitoring WTRUs via a ProSe discovery procedure. A ProSe WTRU may broadcast its location and/or other status information in a discovery message. A ProSe function may encrypt the location and/or other status information for encryption before broadcast. A ProSe WTRU may send its location and/or other status information via a user plane to another ProSe WTRU or ProSe group. A ProSe function may verify whether a WTRU is permitted to disclose and/or process information (e.g., location information) and may indicate to a WTRU whether to disclose information, e.g., before the information is disclosed, and/or whether to process the information.

摘要： A WTRU may send a registration message to a core network (CN) that is associated with a first cell of a first radio access technology (RAT) and a second cell of a second RAT. The WTRU may receive, on the first cell of the first RAT with a first radio resource control (RRC) protocol, a RRC reconfiguration message that includes information for communications with the second cell of the second RAT. The first cell of the first RAT may be utilized for mobility management and a second RRC protocol may be utilized with the second cell of the second RAT.

摘要： Systems, methods, and instrumentalities are disclosed to enable Machine Type Communication (MTC) group communication in 3 GPP. For example, a wireless transmit/receive unit may be used for MTC group communication. The WTRU may contain a processor configured to receive a trigger, such as an SMS trigger. The WTRU may contact a server, such as an Application Server or Proximity based Service function. The WTRU may request additional information from a server. The WTRU may receive information from a server. The WTRU may trigger one or more WTRUs, for example, based on the information received from the server.

摘要： In one aspect, a method of cell processing is disclosed, which includes disposing a plurality of cells on a substrate across which a plurality of projections are distributed and an electrically conductive layer at least partially coating said projections, exposing the cells to a cargo to be internalized by the cells, irradiating the substrate surface (and in particular the projections) with one or more laser pulses having a pulse width in a range of about 1 ns to about 1000 ns so as to facilitate uptake of the cargo by at least a portion of the cells (e.g., the cells positioned in the vicinity of the projections (e.g., within hundreds of nanometer (such as less than 100 nm) of the projections)). In some embodiments, the laser pulses have a pulse width in a range of about 10 ns to about 500 ns, e.g., in a range of about 5 ns to about 50 ns.

摘要： A communication method implemented on a 3rd Generation Partnership Project (3GPP) communication network includes providing an attachment between a group member of a communication group and a group application server, detecting a detachment between the group member and the group application server, and reestablishing the attachment by the 3GPP communication network. A Mobility Management Entity (MME) may provide the attachment. A Group Communication Service Enabler Application Server (GCSE AS) or a Multipoint Service (MuSe) functionality may detect the detachment. The attachment may be reestablished according to the MuSe functionality. A group communication bearer may have a first priority level for allocating resources to the group communication bearer, and a second priority level for allocating resources to the non-group communication bearer. The second priority level may be different from the first priority level. Different Quality Control Indexes (QCIs) may be provided to the group communication bearer and the non-group communication bearer.

摘要： A wireless transmit/receive unit (WTRU) is configured to receive at least three sets of parameters associated with power saving. A first set of the parameters is associated with an idle state. A second set of the parameters is associated with a connected state. A third set of the parameters is associated with not being in a connected state and remains registered with a network and maintains a packet data network (PDN) connection. The WTRU is configured to enter active times based on the third set of parameters on a condition that the WTRU is not in the connected state and remains registered with the network. During the active times, the WTRU is configured to monitor physical downlink control channels (PDCCHs) for paging messages.

摘要： Methods and apparatus may be used for selecting power saving mechanisms in a wireless transmit/receive unit (WTRU). For example, a WTRU may support at least power saving mode (PSM) and/or extended discontinuous reception (eDRX) mode. The WTRU may send a request message including parameters associated with the supported power saving mechanisms, such as an active time for PSM and a preferred DRX value for eDRX mode. The WTRU may receive an accept message including at least one selected parameter indicating the power saving mechanism for the WTRU selected by the network (NW). The WTRU may activate the selected power saving mechanism, and may start a validity timer to define the duration of use of the selected power saving mechanism. In another example, a WTRU configured to use eDRX may receive paging signals for system information (SI) change over a prolonged Broadcast Control Channel (BCCH) modification period.
