Description

Consumption quota monitoring method and device

technical field

The invention relates to the field of mobile communication, in particular to a consumption quota monitoring method and device.

Background technique

With the continuous evolution of the Policy and Charging Control (PCC) architecture, as shown in Figure 1, the PCC architecture includes the following functional entities: Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), Policy and Charging Enforcement Function (Policy and Control Enforcement Function, PCEF), Bearer Binding and Event Reporting Function (BBERF), Application Function (ApplicationFunction, AF), Traffic Detection Function (Traffic Detection Function, TDF), user subscription database (Subscription Profile Repository, SPR), offline charging system (Offline charging system, OFCS), online charging system (Online charging system, OCS).

The PCRF is mainly responsible for the formulation of policies and charging rules, and sends the formulated PCC policies and charging rules to the PCEF through the Gx interface. The PCEF installs and executes the PCC policies, reports related events, and exchanges charging information with the charging system. The PCRF sends the Quality of Service (QoS) rules to the BBERF through the Gxx interface. The BBERF does not exchange charging information with the charging system, but is only responsible for bearer binding and reporting of related events. The PCRF sends the service information to be monitored to the TDF through the Sd interface, and the TDF performs service monitoring and reports it to the PCRF. The AF provides service information to the PCRF through the Rx interface. The SPR stores the service information signed by the user, and the PCRF can query the SPR for the service information signed by the user through the Sp interface. The OCS reports policy counter status information related to user consumption to the PCRF through the Sy interface. The PCEF sends the online charging information to the OCS through the Gy interface for online charging statistics, and sends the offline charging information to the OFCS through the Gz interface. TDF sends service-based online charging information to OCS through the Gyn interface, and sends service-based offline charging information to OFCS through the Gz n interface.

The information transmitted by PCRF and OCS on the Sy interface can be divided into two directions: From PCRF to OCS, the user's consumption information is mainly transmitted, such as the consumption counter and the consumption quota status corresponding to the consumption counter. These information are used as the decision-making input for PCRF to implement PCC Conditions and PCRF subscribe the consumption status corresponding to the user's consumption counter to the OCS. The state of the consumption quota corresponding to the subscribed consumption counter is mainly transmitted from the OCS to the PCRF, and this state can be used as a decision-making input condition for the PCRF to implement the PCC.

PCRF uses the consumption quota request (Spending-Limit-Request, SLR)/consumption quota response (Spending-Limit-Answer, SLA) process to initiate the Sy session for the acquisition and subscription of consumption information, and can also use the SLR/SLA process for consumption information Subscribe for modification. PCRF makes policy judgments based on the acquired consumption information, locally configured service policies, and user attributes, and delivers the generated rules to PCEF. The PCRF uses the STR/STA process to initiate the termination of the Sy session, and cancel the consumption quota status of the subscribed consumption counter. PCRF will not be notified when the user's consumption status changes. OCS uses the Spending-Status-Notification-Request (SNR)/Spending-Status-Notification-Answer (SNA) to initiate a Sy session to notify consumption quota information status changes, PCRF Based on the new consumption status, policy judgments will be made, and rules will be generated and sent to PCEF.

When the OCS detects that the consumption quota state corresponding to the charging counter subscribed by the PCRF changes, it will use the SNR to notify the PCRF of the quota state change according to the Sy session associated with the consumption counter.

The current PCRF system has such an application scenario: PCRF can actively query the consumption quota status of online rate-limited users when they span months, so it will actively initiate an SLR request to query the consumption quota status of the user. Such users may not need OCS when they do not span months Actively push consumption quota status through OCS. In addition, to cancel certain consumption quota subscriptions of users at present, the operation of releasing the session must be triggered through the session termination request (Session-Termination-Request, STR) to cancel the consumption quota subscription, and there is no method to directly cancel the subscription without releasing the session.

As mentioned above, the current subscription method has the following defects: 1. It lacks a query method to directly query the user's consumption quota and does not require OCS to push the consumption quota status. Load level; 2. There is no method to directly cancel the subscription consumption quota status without releasing the session. At present, when the system does not need to subscribe to the consumption quota status temporarily, it can only cancel the subscription by releasing the session. When it is necessary to subscribe to other consumption quota status of the user in the future , re-establish the session and re-subscribe to the consumption quota state. The process of releasing the session and re-establishing the session reduces the processing capacity of the PCRF/OCS system and also increases the load level between the systems.

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

method embodiment

According to an embodiment of the present invention, a method for monitoring a consumption quota is provided. FIG. 2 is a flow chart of the method for monitoring a consumption quota according to an embodiment of the present invention. As shown in FIG. 2 , the method for monitoring a consumption quota according to an embodiment of the present invention includes the following deal with:

Step 201, the policy control and charging rule functional entity PCRF queries the online charging system OCS for the status of the unsubscribed user consumption quota through the consumption quota request SLR message, wherein the SLR message carries the query operation instruction and the user consumption quota that needs to be queried Quota information;

After step 201, 4. OCS checks the status of the consumption quota related to the user query, and returns it through the SLA message;

In step 202, the PCRF receives the consumption quota response SLA message sent by the OCS, and obtains the corresponding consumption quota status of the user from the SLA message.

The technical solution of the embodiment of the present invention further includes the following processing: the start condition is triggered, and the PCRF subscribes to the OCS for a predetermined type of user consumption quota status through an SLR message, wherein the SLR message carries a subscription operation instruction and user consumption quota information that needs to be subscribed ;OCS checks the status of the consumption quota subscribed by the user, returns it through the SLA message, and records the consumption quota information subscribed at the same time. When the status of the consumption quota information changes, it will notify the PRCF of the status change of the consumption quota information through the SNR message; PCRF receives the OCS The subscription success response sent through the SLA message, and when the status of the subscribed user's consumption quota changes, receives the consumption quota status notification request SNR message sent by the OCS, and obtains the status change information of the user's consumption quota from the SNR message. Among them, the above starting conditions include: PCRF makes a policy decision due to the modification of the configuration of the user subscription database SPR, or the request of the policy and charging enforcement function entity PCEF for consumption related quotas, and discovers the state of the user consumption quota that needs to be controlled by the OCS during the policy decision-making process as a policy condition. Subscription under the above conditions is a re-subscription, that is, the PCRF resubscribes to the OCS for the status of the user's consumption quota through the SLR message. When re-subscribing, OCS checks the relevant status of the user's consumption quota, returns it through the SLA message, and records the re-subscribed consumption quota information at the same time. When the status of these consumption quota information changes, the PRCF is subsequently notified of the status change of the consumption quota information through the SNR message .

In practical applications, when PCRF makes a policy decision due to SPR modification configuration or PCEF requesting consumption related quotas, and finds that it is necessary to cancel subscription status of certain types of user consumption quotas of users during the policy decision-making process, PCRF cancels to OCS through SLR message Subscribe to the user's consumption quota status of the scheduled type, where the SLR message carries the unsubscription operation instruction and the user's consumption quota information that needs to be unsubscribed; OCS returns the unsubscription success through the SLA message, and at the same time unsubscribes the corresponding consumption of the user locally Quota information, the PRCF will no longer be notified of the state change of the consumption quota information through the SNR message in the future. The PCRF receives the unsubscribe success response sent by the OCS through the SLA message. It should be noted that, in practical applications, user consumption quotas include multiple types, for example, time, traffic, and so on.

When the PCRF determines that it is no longer necessary to obtain the user consumption quota status of a certain user, it sends a session termination request STR message to the OCS to request the release of the session; the PCRF receives the session release response sent by the OCS through the session termination response STA message. That is to say, PRCF finds that it no longer needs to obtain all the consumption quota status of the user, and then sends a STR message to the OCS, requesting to release the Sy session; after receiving the STR message, the OCS replies to the STA message, and releases the local Sy session information at the same time.

The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 3 is the flow chart of the consumption quota subscription release processing of the embodiment of the present invention; As shown in Fig. 3, PCRF finds in the decision-making process that needs to use the user's consumption state controlled by OCS as policy condition, and PCRF subscribes to OCS through SLR message at this moment For the status of certain consumption quotas of the user, OCS checks the status of the consumption quota of the user and returns it through the SLA message. When the PRCF finds that it needs to obtain the status of unsubscribing the user's consumption quota, it sends a STR message to the OCS. After receiving the STR message, the OCS replies with an STA message to release the Sy session information.

Fig. 4 is a flow chart of consumption quota query subscription cancellation subscription release processing according to an embodiment of the present invention; functional entities such as PCEF, SPR or PCRF trigger the authorization process, PCRF finds that the consumption status of the user needs to be subscribed to the OCS, and subscribes to the OCS through the SLR, and the OCS Reply to the SLA ID to accept this user's consumption quota status monitoring subscription. Due to reasons such as operation policies, the PCRF queries the OCS about the status of certain consumption quotas of the user through the SLR message, and the OCS returns it through the SLA message. PCRF finds that it needs to re-subscribe the user's other consumption quota information status during the policy decision-making process, and re-subscribes the user's other consumption quota information status to the OCS through the SLR message, and the OCS returns through the SLA message. When the PRCF finds that it is no longer necessary to obtain all the consumption quota status of the user, it sends a STR message to the OCS, and the OCS replies with a STA message. As shown in Figure 4, it specifically includes the following processing:

Step 401, functional entities such as PCEF, SPR, or PCRF trigger the authorization process. PCRF finds that the consumption status of users controlled by OCS is used as an input condition for policy decisions, and PCRF has no relevant information locally, and subscribes to OCS through SLR messages. User consumption reminder; the Subscription-Id AVP of the SLR message is used to carry the user's identity (for example: IMSI or MSISDN). The SLR message will carry the consumption counter operation type Policy-Counter-Operate-Type, the type value is subscription, and carry the identifier Policy-Counter-Identifier AVP of these consumption counters subscribed. If it does not carry the Policy-Counter-Identifier AVP, it means to obtain/subscribe the consumption quota status corresponding to all available consumption counters of the user;

Step 402: After receiving the PCRF subscription request, the OCS registers the corresponding consumption notification of the user. OCS uses the Policy-Counter-Status-Report AVP of the SLA message to notify the PCRF of the status of the registered user consumption counter;

Step 403 , the PCRF queries the OCS for relevant user consumption reminders through the SLR message due to reasons such as operation policies. The SLR message will carry the consumption counter operation type Policy-Counter-Operate-Type, the type value is query, and carry the identifier Policy-Counter-Identifier AVP of these consumption counters queried. If no Policy-Counter-IdentifierAVP is carried, it means to query the consumption quota status corresponding to all available consumption counters of the user;

Step 404, after receiving the PCRF query request, the OCS queries the corresponding consumption notification of the user. OCS uses the Policy-Counter-Status-Report AVP of the SLA message to notify the PCRF of the status of the user's consumption counter;

Step 405, functional entities such as PCEF, SPR, or PCRF trigger the re-authorization process. PCRF finds that other consumption states of users controlled by OCS are used as input conditions for policy decisions, and re-subscribes relevant user consumption reminders to OCS through SLR messages. The SLR message will carry the consumption counter operation type Policy-Counter-Operate-Type, the type value is subscription, and carry the identifier Policy-Counter-Identifier AVP of these consumption counters resubscribed;

Step 406: After receiving the PCRF re-subscription request, the OCS re-registers the corresponding consumption notification of the user. OCS uses the Policy-Counter-Status-Report AVP of the SLA message to notify the PCRF of the status of the re-registered user consumption counter;

Step 407 , the PCRF makes a policy decision due to the configuration modification of the SPR or the request of the PCEF to consume related quotas, and during the decision-making process, it is found that it is necessary to cancel the subscription status of certain consumption quotas of the user. The SLR message will carry the consumption counter operation type Policy-Counter-Operate-Type, the type value is unsubscribe, and carry the identifier Policy-Counter-IdentifierAVP of these unsubscribed consumption counters;

Step 408: After receiving the PCRF unsubscription request, the OCS cancels the corresponding consumption notification of the user, and returns the unsubscription success through the SLA message, and then does not notify the PRCF of the status change of the consumption quota information through the SNR message.

In step 409, the PRCF finds that it is no longer necessary to obtain the status of all consumption quotas of the user, and then sends a STR message to the OCS, requesting to release the Sy session;

Step 410, after receiving the STR message, the OCS replies to the STA message and releases the local Sy session information at the same time.

It should be noted that in the embodiment of the present invention, the Policy-Counter-Operate-Type needs to be extended in the SLR message, and the AVP indicates how to operate the consumption quota state corresponding to the user's consumption counter. As shown in Table 1: User consumption quota status operation type Policy-Counter-Operate-Type (0: query; 1: subscribe; 2: cancel subscription).

Table 1

The position of Policy-Counter-Operate-Type in the SLR message is as follows:
