[0006] Also, ADC rules can be applied to all traffic in the entire IP-CAN session, however, each PCC rule is associated with a bearer, so it is unlikely to apply to the entire IP-CAN session

Embodiment Construction

[0049] The following describes the current preference of the PCRF server 1, the PCEF device 3, the TDF devices 2, 2a, 2b and the method of coordinating a PCEF session (established with a PCEF device) with multiple TDF sessions (respectively established with multiple TDF devices in a PCC framework) Example.

[0050] Figure 8 Illustrating a conventional PCC architecture with PCRF server, PCEF device and TDF device installed according to the present invention. This PCC architecture (as described in 3GPP TS 23.203 (v.11.2.0)) includes PCEF 3, Bearer Binding and Event Reporting Function (BBERF) 8, PCRF 1, Application Function (AF) 5, TDF 2, In-line Charging System (OCS) 6, Offline Charging System (OFCS) 7 and Subscription Profile Repository (SPR) 4 functions.

[0051] For the purposes of the present invention, the PCRF server, PCEF device and TDF device (thus they all share the same reference as the PCRF, PCEF and TDF entities) are usually specified in 3GPP TS 23.203 (V.11.1.0) ...

Abstract

The present invention faces the problem of coordinating more than one TDF session for users in the PCC architecture. For this purpose, there is provided a PCRF server, a PCEF device, a TDF device, and a method for coordinating a PCEF session with more than one TDF session, the method comprising: establishing or modifying a PCEF session in the PCRF server ip-CAN session; Select more than one TDF device on the PCRF server; Determine the sequence of each selected TDF device to be determined on the PCRF server, as well as the access information required by each selected TDF device; Initiate a TDF session from the PCRF server towards each selected TDF device, providing applicable ADC rules and routing information indicating the next TDF device to be involved; and pcC rules for submitting IP-CAN sessions from the PCRF server to the PCEF appliance and routing information indicating the first TDF appliance to be involved.

Description

technical field [0001] The invention generally relates to the establishment of a session between a Policy and Charging Control Function (hereinafter referred to as PCRF) and a Traffic Detection Function (hereinafter referred to as TDF). More specifically, the invention relates to the selection of more than one TDF for detecting traffic. Background technique [0002] Policy and Charging Control (PCC) architecture and functionality are specified in 3GPP TS 23.203 (v.11.2.0) of the Evolved 3GPP Packet Switched domain, including 3GPP access (GERAN / UTRAN / E-UTRAN) and non-3GPP access into both. [0003] Traditionally, and for the purposes of this invention, the Policy and Charging Control (PCC) architecture contains the Policy and Charging Enforcement Function (PCEF) (which is responsible for traffic detection and enforcement of policies applicable to user traffic), Policy and Charging Control Function (PCRF) (which is responsible for providing network control of traffic detecti...
