Problems solved by technology

[0018] When TDF is deployed independently, TDF may also fail to report the service data flow template corresponding to the detected application. At this time, PCRF cannot deliver the PCC rule containing the service data flow template to PCEF, so that the usage monitoring and control for this application cannot be realized.
[0019] When the existing usage monitoring control is aimed at the entire IP-CAN session, if an independent TDF is deployed, because there may be applications or data flows in the IP-CAN session that TDF cannot detect and report flow information, TDF will combine the measurement provided by PCRF And the local policy implements corresponding gating or bandwidth limitation for this type of application or data flow (that is, when the bandwidth exceeds the limit, packet loss is performed). For this type of data flow, PCEF's IP-C

Embodiment 1

[0081] Embodiment 1: The PCEF integrates the TDF function, and the TDF adopts a report request mode.

[0082] figure 2 It is a flow chart of the usage monitoring method of Embodiment 1 of the present invention, such as figure 2 As shown, the process includes the following steps:

[0083] Step 201, in the process of the UE requesting to establish an IP-CAN session, the gateway where the PCEF is located receives the IP-CAN session establishment request message, and carries the user identifier and the PDN network requested for access in the IP-CAN session establishment request message The PDN identifier.

[0084] In step 202, the PCEF sends an IP-CAN session establishment instruction message to the PCRF, and the IP-CAN session establishment instruction message carries the user identifier, the PDN identifier and the IP address (IPAddress) allocated to the UE.

[0085] In step 203, the PCRF judges that there is no subscription information of the user according to the user iden...

Abstract

The invention discloses two schemes of a usage monitoring method supporting a traffic detection function (TDF) and a usage monitoring system. According to one scheme, the method comprises the following steps that: a policy and charging rules function (PCRF) entity issues a usage monitoring strategy corresponding to application to a policy and control enforcement function (PCEF) entity of a traffic detection function (TDF), a PCEF entity and an independent TDF, or an independent TDF; and the PCEF entity of the integrated TDF, the PCEF entity and the independent TDF, or the independent TDF executes/execute usage monitoring according to the usage monitoring strategy. Besides, a usage monitoring unit in the system is used for enabling the PCEF, the PCEF of the integrated TDF and the independent TDF to execute the usage monitoring according to the usage monitoring strategy. According to the method and the system in the invention, usage monitoring control at a level that a PCRF can not obtain the service data flow of a service data flow template and usage detection control at an IP connectivity access network (IP-CAN) level under a TDF architecture can be realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication strategy and billing control, in particular to a usage monitoring method and system supporting Traffic Detection Function (TDF, Traffic Detection Function). Background technique [0002] Since the 3rd Generation Partnership Project Phase 7 (3GPP Release7) standard system, policy and charging functions are implemented by a policy and charging control (PCC, Policy and Charging Control) framework. The PCC architecture is a functional framework that can be applied to multiple access technologies. For example, the PCC architecture can be applied to the Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System). ), Global System for Mobile Communication (GSM, Global system for Mobile Communication) / GSM Data Enhanced Evolution (EDGE) Wireless Access Network, Inter...
