  • Publication number: 20190274174
    Abstract: 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.

  • Patent number: 10368375
    Abstract: 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.
