Embodiment 1

[0060] What this embodiment describes is that under the scenario where BBERF does not exist, the process of PCC performing policy control according to the congestion situation of the network, the process includes the following steps:

[0061] In step 301, a user equipment (User Equipment, UE) attaches to the network and initiates an attach procedure, or the UE initiates another procedure for establishing a PDN connection.

[0062] Step 302: After receiving the attach request or the PDN connection establishment request, the PCEF initiates an IP-CAN session establishment request to the PCRF, and provides the PCRF with information such as user ID, PDN ID, and IP address.

[0063] Step 303. If there is no defined user subscription information, the PCRF obtains the user subscription information from the SPR, such as user level, bandwidth allocated to the user, and services allowed to be accessed by the user.

[0064] In step 304, the PCRF returns to the PCEF a response indicating t...

Embodiment 2

[0079] What this embodiment describes is that under the scenario where BBERF exists, the process of PCC performing policy control according to the congestion situation of the network, the process includes the following steps:

[0080] In step 401, the UE attaches to the network and initiates an attach process, or the UE initiates another PDN connection establishment process.

[0081] Step 402. In step 401, after receiving the attach request or the PDN connection establishment request, the BBERF initiates a gateway control session establishment request to the PCRF, and provides the PCRF with user ID, PDN ID, IP address and other information.

[0082] Step 403: If there is no defined user subscription information, the PCRF obtains the user subscription information from the SPR, such as user level, bandwidth allocated to the user, services allowed to be accessed by the user, and the like.

[0083] Step 404: After the PCRF makes a policy decision, it returns a gateway control sess...

Abstract

The present invention discloses a strategy control method, device and system based on congestion control. When PCRF provides strategies to PCEF, instructs the strategy execution conditions; PCEF is perceived by the perception of congestion information and the execution strategy of the congestion execution conditions.check.Based on the strategic control technology of congestion control, the present invention allows PCEF to decide whether to implement the strategy issued by PCRF based on the current congestion situation, and achieve the purpose of reducing network congestion and ensuring user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a policy control method, device and system based on congestion control. Background technique [0002] Currently, the policy and charging control (Policy and Charging Control, PCC) defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is as follows: figure 1 shown. [0003] Among them, the Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF) uses network resources for services to formulate Quality of Service (Quality of Service) and charging policies. To formulate the control policy, the PCRF needs to combine the service information received from the Application Function (Application Function, AF), the user subscription information received from the user subscription database (Subscription Profile Repository, SPR), and the policies configured by the operator. The PCRF will deliver the control policy formulated for ...
