521, PCEF, receiving in this strategy and charging control message situation, determines that target P DN connects.
Particularly, this TDF according to this strategy with in charging control message APN information (this APN information comprise following any one or multiple: the IP address of PDN connection identifier, subscriber equipment and APN) determine APN and determine that this target P DN is connected, this target P DN connects the data flow for PDN all in this APN connects.
522, PCEF carries out policy control to this target P DN connection.
This PCEF can carry out policy control according to this qos parameter to this target P DN connection.Particularly, if this qos parameter only comprises up APN-AMBR, then this PCEF only connects this up APN-AMBR control of execution to this target P DN.Or if this qos parameter comprises up APN-AMBR, descending APN-AMBR and is used to indicate the up APN-AMBR instruction only performing up APN-AMBR and control, then this PCEF only connects this up APN-AMBR of execution to this target P DN.Or if this qos parameter comprises descending APN-AMBR and up APN-AMBR, and this descending APN-AMBR is greater than particular value, and this particular value can take fully enough large.Like this, although this PCEF obtains descending APN-AMBR, but the value of this descending APN-AMBR is enough large, do not affect the control to descending APN-AMBR, so now this PCEF is also equivalent to only connect this target P DN perform this up APN-AMBR and control, namely controls this PDN and connect the up convergence Maximum Bit Rate carried and be not more than this up APN-AMBR.
Method according to Fig. 5, controls strategy and charging to be placed on TDF node device and performs.By using a node to control target data stream implementation strategy and charging, the packet that can be avoided needs to carry out charging is dropped, thus reaches the object of accurate billing.In addition, because first the data flow that up PDN connects needs through PCEF, if perform up APN-AMBR by PCEF, then the inaccurate problem of charging that this PCEF causes due to packet loss can be avoided.Similar, because first the data flow that descending PDN connects needs through TDF, if perform descending APN-AMBR by this TDF, then the inaccurate problem of charging that this TDF causes due to packet loss can be avoided.
