Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0027] figure 1 It is a schematic diagram of the architecture of the PCC system 100 based on Embodiment 1 of the present invention, and the PCC system 100 includes a PCEF 110 , a PCRF 120 and a TDF 130 . When the UE wants to access the network, it needs to perform PCC authentication on the UE. First, the UE sends an access request signaling to the PCEF 110, and the PCEF 110 allocates an IP address for the UE after receiving the access request signaling, and sends a CCR-I message to the PCRF 120 to Requesting the PCRF 120 to authenticate the UE. After determining that the UE has subscribed, the PCRF 120 sends a TSR message to the TDF 130 corresponding to the PCEF, the TSR message includes the ADC rule of the UE that needs to be executed by the TDF 130, and replies to the PCEF 110 with For the CCA-I me...

Abstract

The invention discloses a method, a device and a system for realizing application detection and control. The method comprises the following steps that a TDF acquires the IP address of UE correspondingto a target Internet flow, wherein the target Internet flow is the Internet flow that does not have a corresponding application detection and control ADC rule in the Internet flow transmitted throughthe TDF; an ADC rule request message containing the IP address of the UE is sent to PCRF; an ADC rule response message containing the ADC rule of the UE sent by the PCRF is received; and according tothe ADC rule, application detection and control are executed to the Internet flow of the UE. Therefore, correlation services can be effectively developed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for realizing application detection and control. Background technique [0002] Telecom operators plan networks according to the standards of the 3rd Generation Partnership Project (3GPP), among which the policy and charging control (Policy and Charging Control, PCC) standard TS23.203 is one of the important 3GPP standards. [0003] The basic PCC architecture includes Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), Policy and Charging Enforcement Function (Policy and Charging Enforcement Function, PCEF) and Traffic Detection Function (Traffic Detection Function, TDF). [0004] When user equipment (User Equipment, UE) wants to access the network, PCC authentication needs to be performed on the UE. First, the UE sends an access request signaling to the PCEF, and the PCEF allocates an IP address for the UE aft...
