Third embodiment:

FIG. 3 is a flowchart of a consumption quota interaction method according to a third embodiment of the present invention. As shown in FIG. 3, in the embodiment, the consumption quota interaction method provided by the present application includes the following steps:

S301: The PCRF determines that it is required to acquire a policy counter status in a specified area.

In fact, the PCEF (Policy and Charging Enforcement Function) in the PCC architecture sends an IP-CAN session establishment indication message to the PCRF, which has a user identifier, and the PCRF is from the SPR (Subscription Profile Repository). Obtaining the subscription information of the user, making a rule decision, and sending a session establishment response message to PCEF, PCRF and PCEF complete the creation of an IP-CAN session and save the IP-CAN session information and user information on the PCRF. After that, the PCRF determines that the policy counter state needs to be acquired according to a certain condition, such as configuration, and only considers the policy counter state in the specified area, and proceeds to the next step.

Alternatively, the PCEF sends an IP-CAN session modification indication message to the PCRF, or the PCRF internal event is triggered, and the PCRF needs to re-execute the rule decision. At this time, the PCRF determines that the policy counter state needs to be acquired according to a certain condition, such as configuration, and only considers Specifies the status of the policy counter for the zone. If a Sy session has been created and the policy counter for that zone is not subscribed, proceed to the next step.

S302: The PCRF sends an SLR message with location information and a policy counter to the OCS.

In this step, after the PCF completes the IP-CAN session with the PCEF, it determines that it needs and only needs to acquire the consumption quota status at the specified location, and the PCRF sends an initial SLR message to the OCS, and has the user identifier in the initial SLR message. And the policy counter and location information to be subscribed to, such as adding an AVP (Attribute Value Pair) to construct the request message to include location information.

The PCEF sends an IP-CAN session modification indication message to the PCRF, or triggers an internal event of the PCRF. When the PCRF needs to re-execute the rule decision, it determines that the consumption quota status needs to be acquired only at the specified location, and the PCRF sends the intermediate SLR message to the OCS, and The intermediate SLR message has a user identifier and a policy counter and location information to be subscribed.

S303: The OCS acquires a policy counter and location information.

After receiving the initial SLR message or the intermediate SLR message of the PCRF, the OCS decodes the SLR message, parses the policy counter and the location information, determines the specified location according to the location information, saves the session information, and then performs the subsequent process.

S304: The OCS obtains a corresponding consumption quota and sends it to the PCRF.

The OCS searches for the consumption quota associated with the policy counter according to the user identifier and the policy counter of the SLR message, generates a policy counter report according to the consumption quota, and generates a consumption status notification request SNR message to the PCRF, where the policy counter status is generated. .

S305: The PCRF acquires a policy counter status.

After receiving the SNR message of the consumption status notification request, the PCRF decodes and acquires the policy counter status, and further performs rule decision according to the policy counter status.

S306: The OCS monitors the consumption quota status.

The OCS monitors the consumption quota status associated with the policy counter to determine the consumption quota status. If the policy counter associated with the PCRF subscription changes the consumption quota status, the process proceeds to step S307, and if the policy counter associated with the PCRF subscription does not change the consumption quota status, Repeat this step.

S307: The OCS determines whether it is necessary to send the changed consumption quota status.

The OCS determines whether the location of the consumption quota status is in the designated location of the PCRF subscription, and if the changed consumption quota status is in the designated location, proceeding to step S308; if the changed consumption quota status is not in the designated PCRF subscription Location, the process ends.

S308: The OCS sends the changed consumption quota status.

The OCS constructs and sends an SNR message to the PCRF, which includes the changed consumption quota status associated with the policy counter, and the policy counter is in a valid period.

S309: The PCRF acquires the changed consumption quota status.

After receiving the SNR message, the PCRF saves the consumption status associated with the policy counter, and responds to the SNA (Spending-Status-Notification-Answer) response message to the OCS, and performs rule decision according to the changed consumption quota status associated with the policy counter. .

The application extends the SLR message, newly adds an AVP in the message layer, and is set to have a policy counter based on the specified location, the type is Grouped, and the policy counter based on the specified location is defined by the following code:

For the SLR message format, refer to the 3GPP specification named 3GPP TS 29.21, where the Policy-Counter-Identifier of the message layer is the protocol existing AVP, indicating the location-independent policy counter; the Policy-Counter-Identifier in the Policy-Counter-Information is added. Indicates location related The policy counter, 3GPP-User-Location-Inf, represents the location information related to the policy counter. For the definition of 3GPP-User-Location-Info, see the following code in the 3GPP specification named 3GPP TS 29.061.

Embodiments of the present invention further provide a computer readable storage medium storing computer executable instructions that are implemented when the computer executable instructions are executed.

In summary, through the implementation of the present application, at least the following beneficial effects exist:

Providing SLR messages with location information and policy counters of specified locations, one-time subscription of consumption quota status of only one or more specified locations, reducing the number of messages sent by the PCRF to the OCS, thereby reducing system load, and in addition, OCS does not need When the consumption quota status changes, the SNR message is sent to the PCRF, and the message notification PCRF is sent only when the consumption quota status of the specified location of the PCRF subscription changes; that is, the application subscribes to the policy in the specific location by using the existing interface.
