S101：PCRF实体获取远端UE的签约信息。
具体地，在ProSe应用场景中，中继UE在网络附着过程中建立PDN连接，远端UE通过发现过程发现可以为其提供数据传输的中继UE，可以是中继UE发送广播消息，远端UE通过广播消息发现中继UE。远端UE和中继UE建立一对一通信，其中，可以是远端UE发送通信请求给中继UE以建立一对一通信，该通信请求中包含了远端UE的标识。中继UE将远端UE的标识发送给移动性管理实体(Mobility Management Entity；简称MME)，MME将远端UE的标识发送给PGW，PGW将远端UE的标识发送给PCRF。
PCRF实体可以根据远端UE的标识获取远端UE的签约信息。远端UE的签约信息可以是远端UE在入网时签约的可以发起业务的类型、数据传输速率、带宽、时延及误包率等信息。
需要说明的是，远端UE的标识还可以由中继UE通过其它网元传输至PCRF实体，本实施例并不以此为限，只要PCRF实体最终能够获得远端UE的标识即可。
S102：PCRF实体根据远端UE的签约信息和业务QoS，确定中继UE的QoS规则。
具体地，PCRF实体需要获取业务QoS，业务QoS是远端UE发起的具体的业务的QoS要求，例如，远端UE发起的语音业务，则业务QoS就是语音业务的QoS要求。PCRF实体可以从远端UE的应用功能(Application Function；简称：AF)实体中获取业务QoS，也可以从中继UE中获取业务QoS，本实施例并不以此为限。
需要说明的是，PCRF在确定中继UE的QoS规则时，还需要参考已存储在PCRF实体中的中继UE的签约信息。
PCRF实体可以先根据远端UE的签约信息判断远端UE是否可以发送该业务类型，这里的业务类型指的就是PCRF实体获取到的业务QoS所对应的 业务类型。如果远端UE可以发起该业务，则再判断中继UE的签约信息能否满足该业务QoS，如果能满足，则可以确定该业务QoS为中继UE的QoS规则。当然，如果中继UE的签约信息能满足该业务QoS也可以确定大于该业务QoS而小于等于中继UE的签约信息的任何一个QoS为中继UE的QoS规则。
S103：PCRF实体向PGW发送QoS规则，QoS规则用于PGW修改或建立中继UE的承载，中继UE的承载用于中继UE转发远端UE的数据。
具体地，PCRF实体将QoS规则发送给PGW，PGW根据QoS规则对中继UE的承载进行处理包括：PGW根据QoS规则进行承载建立或承载修改。PGW通过发送信令给服务网关(Serving Gate Way；简称：S-GW)，S-GW发送信令给MME等网元实现PGW修改或建立中继UE的承载。中继UE的承载用于中继UE转发远端UE的上行数据或下行数据。
可选的，本实施例中，QoS规则还可以用户PGW删除中继UE的承载。
本实施例提供的数据处理方法，通过PCRF实体获取远端UE的签约信息，根据远端UE的签约信息和业务QoS，确定中继UE的QoS规则，PCRF实体向PGW发送中继UE的QoS规则，QoS规则用于PGW修改或建立中继UE的承载，中继UE的承载用于中继UE转发远端UE的数据，在远端UE通过中继UE与网络侧进行通信时，能够使PCRF实体根据远端UE的签约信息和业务QoS确定中继UE的QoS规则，进而使PGW根据中继UE的QoS规则修改或建立中继UE的承载进行，中继UE在中继UE的承载上转发远端UE的数据，从而，保证了远端UE的业务QoS。
图2为本发明实施例提供的数据处理方法实施例二的流程示意图。在上述实施例一的基础上，S101之前还包括：
S201：PCRF实体接收PGW发送的远端UE的标识。
具体地，可以有以下三种实现方式：
第一种实现方式：远端UE的标识可以是国际移动用户识别码(International Mobile Subscriber Identification Number；简称：IMSI)。当远端UE的标识为IMSI时，远端UE可以将IMSI携带在通信请求中发送给中继UE，中继UE可以通过将远端UE的IMSI携带在非接入层(Non-Access Stratum；简称：NAS)消息中发送给MME。MME依据远端UE的IMSI对 远端UE进行授权检查，MME可以通过从中继UE和远端UE的归属签约用户服务器(Home Subscriber Server；简称：HSS)中读取的签约消息对远端UE进行授权检查，授权检查包括：该远端UE能否使用该中继UE与网络侧进行数据传输以及该远端UE是否可以触发该中继UE的承载建立或修改。MME对远端UE进行授权检查通过后，将远端UE的IMSI通过GPRS隧道协议(GPRS Tunnelling Protocol；简称：GTP)消息发送给PGW，PCRF实体接收PGW发送的远端UE的IMSI。
需要说明的是，中继UE也可以将远端UE的标识，即IMSI，携带在协议配置选项(Protocol Configuration Option；简称：PCO)中发送给MME，此时，MME不对PCO进行解析，因而，此时MME不对远端UE进行授权检查，而是直接将远端UE的标识发送给PGW，PCRF实体接收PGW发送的远端UE的IMSI。
第二种实现方式：远端UE的标识还可以是临时标识，该临时标识可以是近距离业务功能(ProSe Function)实体分配给远端UE的。远端UE将临时标识发送给中继UE，中继UE可以通过NAS消息将临时标识发送给MME，MME依据该临时标识从近距离业务功能实体中获取与该临时标识对应的IMSI。MME获得远端UE的IMSI之后，其余的实现方式与上述第一种实现方式相同，此处不再赘述。
需要说明的是，此种实现方式中，远端UE的临时标识也可以是MME分配的。如果远端UE的临时标识是MME分配的，远端UE将临时标识发送给中继UE，中继UE可以通过NAS消息将临时标识发送给MME，MME依据该临时标识得到与该临时标识对应的IMSI。
第三种实现方式：远端UE将其标识携带在通信请求中发送给中继UE，中继UE通过其与近距离业务功能实体的接口PC3接口将远端UE的标识发送给近距离业务功能。近距离业务功能实体通过HSS向MME发送远端UE的标识或者近距离业务功能直接向MME发送远端UE的标识。
同样的，远端UE的标识可以是IMSI，如果远端UE的标识为IMSI，MME得到IMSI后，剩余的实现方式与上述第一种实现方式相同，此处不再赘述。如果远端UE的标识为临时标识，MME得到临时标识后，剩余的实现方式与上述第二种实现方式相同，此处不再赘述。
本实施例在上述实施例一的基础上，S101具体包括：
S202：PCRF实体根据远端UE的标识从SPR中获取远端UE的签约信息。
具体地，PCRF实体从用户策略数据库(Subscription Profile Repository；简称：SPR)中获取远端UE的签约信息，签约信息包括允许远端UE发起的业务类型以及远端UE的策略与计费控制(Policy and Charging Control；简称：PCC)规则等。
进一步地，PCRF在获得远端UE的签约信息之后，将远端UE的签约信息存储到中继UE的上下文中，中继UE的上下文表示PCRF中保存的关于中继UE的信息，例如，中继UE的签约信息。
在上述实施例一的基础上，S102之前还包括：
S203：PCRF实体从远端UE的AF实体接收业务QoS。
具体地，在PCRF获取到远端UE的签约信息之后，远端UE可以通过中继UE的PDN连接发送业务请求信令给远端UE的AF实体。AF实体接收到远端UE的业务请求信令之后，依据该业务请求信令向PCRF实体发送远端UE的业务QoS。该业务QoS可以包括业务的类型及业务所需的带宽、传输速率等信息。
