Abstract

According to an embodiment of the present invention, a method of transmitting and receiving data in a traffic detection function (TDF) comprises the steps of receiving a downlink data packet data unit (PDU); applying a routing policy to the received downlink data PDU; and forwarding the downlink data PDU to which the routing policy is applied, to a packet data network gateway. According to an embodiment of the present invention, the method and apparatus can provide a charging function of an application level by providing the method and the apparatus for implicitly selecting and transmitting the classified traffic.

Description

technical field [0001] Embodiments of the present specification relate to a data traffic transmission method and apparatus used in a communication system, and in particular to a method and apparatus for selectively transmitting classified traffic in an implicit manner. Background technique [0002] The 3GPP architecture from Release 11 includes the Traffic Detection Function (TDF). TDF monitors application traffic flow. This is achieved by means of a packet data gateway (P-GW). but if figure 1 As shown, an important setting option is to set TDF obviously. [0003] figure 1 is a diagram showing a TDF setup in a communication system. [0004] refer to figure 1 , the communication system may include an operator control network 110 and a packet data network (PDN) 170 . [0005] Operator Control Network 110 may include Policy Charging Resource Function (PCRF) 120 , PDN Gateway (PDN GW) 130 , Traffic Detection Function (TDF) 140 , and User Equipment (UE) 150 . The communic...
