application example 1

[0084] like image 3 As shown, the PCRF non-roaming architecture CCR-U event triggers the switching process of the charging policy, including the following steps: wherein, the above-mentioned external event triggers include user roaming switching or other events:

[0085] (1) After the post-paid user enters the roaming area, the PCEF reports the SGSN CHANGE event to the PCRF through the CCR-U message;

[0086] Here, it is assumed that postpaid users go online normally locally, and the offline charging policy is implemented.

[0087] (2) The PCRF updates the currently saved relevant information according to the CCR-U message;

[0088] For example, in this example, the CCR-U message will carry the current SGSN address of the user, and the PCRF will update the currently saved SGSN address according to the address. Sometimes the CCR-U message will also carry the usage information of the current user at the same time, and accordingly, the PCRF will also update the corresponding i...

application example 2

[0098] like Figure 4 As shown, under the PCRF non-roaming architecture, the PCRF internal event triggers the switching method of the charging policy. The internal event here is assumed to be a policy update triggered by a user's usage reaching a threshold, including the following steps:

[0099] (1) When a user's usage reaches a threshold, the policy update decision-making process is triggered internally;

[0100] It is assumed that the user is normally online before step (1), and the usage has not reached the threshold, and the offline charging policy is executed;

[0101] (2) The threshold event triggers the internal policy decision-making process. According to the charging policy switching conditions, it is determined that the charging policy needs to be switched, and the original offline charging is switched to online charging.

[0102] A) Assume that the PCRF is configured with the following charging policy switching conditions:

[0103] A user's usage exceeds the thresh...

application example 3

[0112] like Image 6 As shown, the PCEF triggers the switching of the charging policy by reporting an event (such as the user enters a roaming area), including the following steps:

[0113] (1) After the user enters the roaming area, the PCEF reports the SGSN CHANGE event to the home V-PCRF through the CCR-U message; here it is assumed that the user executes the offline charging strategy locally;

[0114] (2) V-PCRF updates the user session information according to the CCR-U message;

[0115] (3) V-PCRF forwards the CCR-U message to the H-PCRF through the S9 interface;

[0116] (4) The H-PCRF makes a decision according to the received CCR-U message and the currently configured charging strategy switching condition, and obtains that the user needs to switch the charging strategy;

[0117] A) It is assumed that H-PCRF has the following charging policy switching conditions:

[0118] The user transitions from the non-roaming state to the roaming state; the corresponding chargin...

Abstract

A method and system for real-time switching of charging control policies, the method comprising: when a policy and charging rule function (PCRF) determines that a user satisfies a charging policy switching condition, sending a message to a policy and charging execution function (PCEF) The notification message carries the corresponding charging policy and charging address after switching; after receiving the notification message, the PCEF selects the corresponding charging address to charge the user according to the charging policy after switching. The system includes: PCRF, configured to send a notification message to PCEF when it is judged that the user meets the charging policy switching condition, which carries the corresponding charging policy and charging address after switching; After the notification message is sent, a corresponding charging address is selected to charge the user according to the above-mentioned charging policy after switching. By adopting the present invention, the user's charging strategy can be controlled more flexibly, so as to achieve the rationality, real-time and accuracy of the charging.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for real-time switching of charging control strategies. Background technique [0002] Faced with the rich mobile data value-added services in the current network and the diversity of data users accessing the Internet, in order to avoid malicious arrears caused by excessive fees due to roaming or other situations, it is hoped that for a certain type of users, when the user is from non-roaming When the state enters the roaming state, the user is billed online. When the user's fee exceeds a certain threshold, a reminder is given to the user, and the data connection is cut off, forcing the user to go offline. [0003] The realization of this function is related to the execution capability of PCEF (Policy and Charging Enforcement Function, Policy and Charging Enforcement Function). Some PCEFs can obtain user types from relevant network elements, and judge whether to perf...
