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.
