example 1

[0058] In this example, the delivery of the PCC policy is initiated by the PCEF to the PCRF. Specifically, when a user initiates an IP-CAN session request, the PCEF requests the PCC policy from the PCRF after receiving the request from the user, and the PCRF queries the SPR to obtain the user subscription information after receiving the request message. Based on the traffic information that the user has already used, the service needs to add a reservation request for reporting the traffic information to the delivered PCC policy, and reserve the traffic information currently used by the user to the PCEF. After receiving the PCC policy message, the PCEF requests the OCS for the credit limit and at the same time obtains the traffic information used by the user. After the OCS returns the requested credit line and the traffic information used by the user to the PCEF, the PCEF reports the traffic information used by the user to the PCRF. If it is necessary to update the existing PC...

example 2

[0069] In this example, the delivery of the PCC policy is triggered by the network side or initiated by the SPR to the PCRF. Specifically, when the user is in the session, the PCRF receives a message from the SPR (the message that the user's subscription information changes) or the PCRF is triggered by the network side, and the PCRF needs to send a new request for scheduled traffic information to the PCEF (not sent before) reservation request), PCEF will install a new reservation request after receiving the message, and report the scheduled traffic information notification to PCRF after meeting the reservation conditions. If it is necessary to update the existing PCC policy, PCRF will formulate a new PCC The policy is delivered to the PCEF, or the previously delivered PCC policy is modified or deleted. Figure 5 It is a signaling flow chart of the processing instance 2 of the policy and charging control method according to the embodiment of the present invention, which is comb...

example 3

[0076]In this example, the update of the PCC policy is initiated by the SPR to the PCRF. Specifically, when the user is in the session, the PCRF receives a message from the SPR (that is, a message that the user subscription information changes) or the PCRF is triggered by the network side, and the PCRF learns that it needs to update the scheduled flow information to the PCEF, and the PCEF receives the message After that, update the original reservation request, and report the scheduled traffic information notification to the PCRF after meeting the reservation conditions. If it is necessary to update the existing PCC strategy, PCRF will formulate a new PCC strategy and send it to PCEF, or Modify and delete the previously issued PCC policy. Figure 6 It is a signaling flow chart of Example 3 of the policy and charging control method according to the embodiment of the present invention, combined below Figure 6 , to describe the above processing in detail:

Abstract

The present invention discloses a strategy, accounting control method and a system, wherein the method comprises the following procedures: sending down reservation strategy and accounting control PCC strategy to strategy and accounting executing function entity PCEF by strategy and accounting rule decision-making entity PCRF, and adding reservation request of flow information to be reported in reservation PCC strategy; searching flow information and transmitting flow information to PCRF while applying credit line to online accounting system according to reservation request of report flow information in reservation PCC strategy by PCEF, wherein flow information means used flow by user; making PCC strategy and transmitting it down to PCEF according to flow information from PCEF by PCRF. The method according to the invention can make strategy based on user flow information by PCRF.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a policy and charging control method and system. Background technique [0002] At present, in the policy and charging control (Policy and Charging Control, PCC for short) architecture of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short), such as figure 1 As shown, it specifically includes: policy and charging rules decision-making entity (Policy and Charging Rules Function, referred to as PCRF), user subscription database (SubscriptionProfile Repository, referred to as SPR) connected to PCRF through Sp interface, through Rx interface and The application function entity (Application Function, referred to as AF) connected to PCRF, the bearer binding and event reporting entity (Bearer Binding and EventReport Function, referred to as BBERF) connected to PCRF through the Gxx interface, and the strategy connected to PCRF through t...
