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.

Abstract: 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.

Abstract translation: 描述了通过无线发射/接收单元（WTRU）来赞助服务和优先业务处理（即，数据连接）的装置和方法。 第一WTRU可以经由应用服务器（AS）来启动对第二WTRU的用户赞助。 第一WTRU可以从AS接收服务触发，并将服务触发转发给第二WTRU。 然后，第二WTRU可以使用服务触发来发起与AS的赞助会话，以便从AS接收服务。 第一WTRU还可以请求AS向第二WTRU传输信用。 AS可以与包括在线计费功能（OCF）和计费数据功能（CDF）的计费系统建立直接通信链路。 AS可以向网络发送请求以提供将内容递送到第二WTRU所需的优先业务处理。
