Example

[0083] Application example one

[0084] Such as 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 external event trigger includes user roaming switching or other events:

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

[0086] It is assumed that the post-paid user goes online normally locally and executes the offline charging strategy.

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

[0088] For example, in this example, the CCR-U message will carry the user's current SGSN address, and the PCRF will update the currently saved SGSN address based on this address. Sometimes the CCR-U message will also carry the usage information of the current user. Accordingly, the PCRF will also update the corresponding information currently saved...

Example

[0097] Application example two

[0098] Such as Figure 4 As shown, in the PCRF non-roaming architecture, PCRF internal events trigger the switching method of the charging policy. The internal events here are assumed to be a policy update triggered by a certain user usage reaching a threshold, including the following steps:

[0099] (1) When a certain amount of the user reaches the threshold, the policy update decision process is triggered internally;

[0100] It is assumed that before step (1), the user is online normally, the usage does not reach the threshold, and the offline charging strategy is implemented;

[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 strategy needs to be switched, and the original offline charging is switched to online charging.

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

[0103]...

Example

[0111] Application example three

[0112] Such as Image 6 As shown, the PCEF triggers the switching of the charging policy by reporting an event (such as a user entering 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 policy locally;

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

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

[0116] (4) The H-PCRF makes a decision based on the received CCR-U message and the currently configured charging policy switching conditions, and concludes that the user needs to switch the charging policy;

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

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

Abstract

The invention discloses a method and system for switching charging control policies at real time. The method comprises the following steps: sending a notification message to a policy and charging executive function (PCEF) when the condition that a user satisfies charging policy switching conditions is judged by a policy and charging rule function (PCRF), wherein the notification message carries corresponding switched charging policies and charging addresses; selecting the corresponding charging addresses according to the switched charge policies after the notification message is received by the PCEF, so as to charge the user. The system comprises the PCRF and the PCEF, wherein the PCRF is used for sending the notification message to the PCEF when the condition that the user satisfies the charging policy switching conditions is judged by the PCRE, wherein the notification message carries the corresponding switched charging policies and charging addresses; and the PCEF is used for selecting the corresponding charging addresses according to the switched charging policies after the notification message is received by the PCEF, so as to charge the user. The method and system provided by the invention can be used for more flexibly controlling the charging policy of the user, so as to achieve reasonability, timeliness and accuracy of charging.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method and system for real-time switching of charging control strategies. Background technique [0002] In the face of the rich mobile data value-added services in the current network and the diversity of data users’ Internet access, in order to avoid malicious arrears caused by high fees due to roaming or other circumstances, it is hoped that for a certain type of user, when the user is not roaming When the state enters the roaming state, the user is charged online, and when the user's fee exceeds a certain threshold, the user is reminded, the data connection is cut off, and the user is forced to go offline. [0003] The realization of this function is related to the execution capability of the PCEF (Policy and Charging Enforcement Function). Some PCEFs can obtain user types from related network elements and determine whether online charging needs to be performed for the user ac...
