摘要： Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.

摘要： 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.

摘要： A method of communicating using proximity services (ProSe) is disclosed. A base station receives at least one aggregate maximum bit rate (AMBR) parameter from a network entity. The at least one AMBR parameter comprises a maximum bit rate that a first wireless transmit/receive unit (WTRU) can use for data sent on one or more ProSe bearers. The base station receives a request from the first WTRU to establish the one or more ProSe bearers with a second WTRU. The request comprises priority information of the one or more ProSe bearers determined by the first WTRU. The base station sends an indication to the first WTRU to establish a ProSe communication over the one or more ProSe bearers based on at least the AMBR parameter and the priority information of the one or more ProSe bearers.

摘要： Systems, methods, and instrumentalities are described for IP flow mobility. A WTRU may receive a trigger for initiating IFOM and/or create one or more routing rules. The WTRU may send the routing rules to a Trusted WLAN Access Network (TWAN) using signaling. A TWAN may receive routing rules from a WTRU using signaling. The TWAN may send the routing rules to a PDN gateway. The routing rules may be sent to the gateway using an S2a reference point. A TWAN may receive one or more routing rules from a PDN gateway. The TWAN may send the routing rules to a WTRU using signaling. The signaling may be one or more of: EAP signaling, Layer-3 (L3) signaling, WLCP signaling, IEEE 802.11 signaling, Non Access Stratum (NAS) signaling, and/or Layer-2 (L2) signaling.

摘要： 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.

摘要： Methods and devices are described for communication using proximity services (ProSe). An aggregate maximum bit rate parameter (AMBR) may limit a data rate that may be transmitted by one or more ProSe bearers. A wireless transmit-receive unit (WTRU) may request authorization from the network prior to establishing a ProSe bearer specifying a required quality of service (QoS) or other requirements. Each ProSe bearer may have a corresponding EPS bearer to support service continuity. Packets may be evaluated by a WTRU first using a ProSe check to determine if the packet is destined for a ProSe bearer and then using a packet filter or filters in order of precedence. Embodiments may include methods of initiation communication after discovery. Embodiments may include methods of maintaining session continuity when traffic is switched between an evolved packet system (EPS) bearer and a ProSe bearer.

摘要： A method and apparatus for triggering a machine type communication (MTC) wireless transmit/receive unit (WTRU) is disclosed. An MTC WTRU receives a message that indicates control period configuration information associated with an extended discontinuous reception (DRX) cycle. The MTC WTRU monitors a paging channel during a control period. The MTC WTRU connects, in response to receiving a paging message during the control period, to an MTC server and transmits data to the MTC server.

摘要： An apparatus and method are described for sponsoring service and preferential traffic handling, (i.e., data connectivity) by wireless transmit/receive units (WTRUs). A first WTRU may initiate user sponsoring of a second WTRU via an application server (AS). The first WTRU may receive a service trigger from the AS and forward the service trigger to the second WTRU. The second WTRU may then initiate a sponsored session with the AS using the service trigger in order to receive a service from the AS. The first WTRU may also request the AS to transfer a credit to the second WTRU. The AS may establish a direct communication link with a charging system including an online charging function (OCF) and a charging data function (CDF). The AS may send a request to a network to provide preferential traffic handling needed to deliver content to the second WTRU.
