摘要： Methods and apparatuses for offloading traffic from a third generation partnership project (3GPP) access network to a non-3GPP access point (AP) are disclosed. A 3GPP access network entity may receive subscription information associated with a wireless transmit receive unit (WTRU). The 3GPP access network entity may further receive traffic associated with the WTRU. The 3GPP access network entity may further determine whether to offload the traffic to the non-3GPP AP based on the subscription information. The 3GPP access network entity may also forward the traffic to the non-3GPP AP based on its determination.

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 for enabling local content sharing are described. A wireless transmit/receive unit (WTRU) transmits a non-access stratum (NAS) message with a content sharing session request to a network entity. The network entity verifies that the WTRU and a sharing WTRU are allowed to participate in a content sharing session. Upon verification, the network entity sends a NAS response with the content sharing session set-up information to the WTRU and sends a resource allocation request for the content sharing session to other network entities. The WTRU establishes the content sharing session between the WTRU and sharing WTRU using a local gateway (LGW) connection absent non-local entity connections and transmits content between the WTRU and the other WTRU using the LGW connection during the content sharing session.

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： 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： A method and apparatus for machine type communication (MTC) authentication and triggering may be performed by an MTC interworking function (MTC-IWF). On a condition an Internet protocol (IP) connection does not exist between a services capability server (SCS) and an MTC device, a device trigger message may be received by the MTC device over a Tsp interface. The device trigger message may include a cryptographic key and may have an associated level of urgency. The method may further comprise determining a level of network congestion and transmitting the device trigger, including the received cryptographic key, to the MTC device in accordance with the associated level of urgency. A report may be sent to the SCS, associated with the determined level of network congestion, to indicate either success or failure of the device triggering procedure. The received cryptographic key may be used to secure an IP connection.

摘要： Systems, methods, and instrumentalities are disclosed to describe reporting and/or reacting to a mobility event. A wireless transmit/receive unit (WTRU) may comprise a processor configured, at least in part, to establish a proximity service (ProSe) session with a second WTRU, detect the occurrence of a mobility event in a cellular network while the ProSe session is ongoing, determine a type of action to be performed with respect to the ProSe session based on one or more of the type of mobility event and type of ProSe session, and transmit a notification to a node in the cellular network, wherein the notification includes an indication of an action to be performed on the ProSe session. The node may be one of an evolved Node B (eNB), proximity server, or mobility management entity (MME). The node may be the second WTRU.

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.
