Summary:The present invention faces the issue of racing conditions occurring during the establishment of an IP-CAN session in PCC architecture and a TDF session between a PCRF and a TDF of the PCC architecture. To overcome this issue, the present invention provides for cooperating apparatuses carrying out a method of establishing a Traffic Detection Function "TDF" session in a Policy and Charging Control "PCC" architecture with a Policy and Charging control Rules Function "PCRF", a Policy and Charging Enforcement Function "PCEF" and a TDF, the method comprising the steps of: signalling an IP-CAN session establishment from a PCEF towards a PCRF; selecting at the PCRF a TDF for detecting and reporting traffic through the IP-CAN session; initiating from the PCRF establishment of a TDF session with the TDF; submitting from the PCRF towards the TDF the ADC rules to be installed for the IP-CAN session; and submitting from the PCRF towards the PCEF the PCC rules to be installed for the IP-CAN session. This method thus ensures that the TDF session has been established before having completed the establishment of the IP-CAN session.
