    Abstract: Wireless transmit receive units (WTRUs) and methods implemented in WTRUs are described. A method includes transmitting idle mode discontinuous reception (DRX) parameters to a serving general packet radio service (GPRS) support node (SGSN)/mobile management entity (MME) during one of a tracking area update (TAU) and a routing area update (RAU) procedure and implementing the DRX mode of operation using the transmitted DRX parameters. The DRX parameters are for a DRX mode of operation that has longer DRX intervals than a regular DRX mode of operation.

    Abstract: 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.

    Abstract: 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.

    Abstract: Methods, apparatuses and systems for user-plane congestion management are provided. Among these method, apparatuses and systems is a method, implementable by a base station (and/or a serving gateway), for mitigating user plane congestion. The method may include sending a congestion indication to a core network; receiving a general packet radio system (GPRS) tunneling protocol (GTP) packet including an first internet protocol (IP) packet associated with a first flow within a bearer; obtaining, from a header of the GTP packet, an indicator indicative of a priority of the IP packet, wherein the indicator was inserted into the header of the GTP packet by the core network responsive to the congestion indication; and dropping any of the GTP packet and the first IP packet on condition that a priority of a second IP packet associated with second flow within the bearer takes precedence over the priority of the first IP packet.

    Abstract: Techniques may be used for restricted direct discovery in proximity services (ProSe). A ProSe function may receive from a discovery wireless transmit/receive unit (WTRU) a restricted ProSe Application identity (ID) of an application located at the discoverer WTRU requesting ProSe discovery. The ProSe function may derive a first and second ProSe codes for the discoveree WTRU and discoverer WTRU, and provide the ProSe codes to the discoverer and/or discoveree WTRUs. A ProSe application server may receive a revocation message from an announcing WTRU indicating a revoked WTRU. The ProSe application server may provide a ProSe discovery WTRU ID for the revoked WTRU to a ProSe Function. The ProSe function may instruct the announcing WTRU to stop announcing a ProSe code known by the revoked WTRU, and may provide a new ProSe code to at least one WTRU authorized to discover the announcing WTRU.
