Description

Method, device and system for bandwidth control

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, device, and system for bandwidth control.

Background technique

The Traffic Monitoring System of the 3rd Generation Partnership Project (3GPP) includes Policy and Charging Enforcement Function (PCEF) entity, Policy and Charging Rule Function (PCRF). ) Entity and Online Charging System (OCS).

When the user uses the data service, the PCEF first applies for the available bandwidth to the PCRF. The PCRF obtains the bandwidth reference factor level from the OCS, calculates the bandwidth according to the level, and returns the bandwidth to the PCEF. The PCEF reports the charging request to the OCS completion fee. Reserved and deducted.

For example, the PCRF entity and the OCS convention reference count identifier (Counter-ID) and the reference count level (Counter-Level), the PCRF obtains the Counter-ID and the corresponding Counter-Level that are valid in the current service, and then based on the Counter-Level and the locally configured A bandwidth decision strategy is used to complete the bandwidth decision and deliver the bandwidth decision to the PCEF entity. When the OCS monitors the counter-level change corresponding to the counter-ID, it will send the updated Counter-Level to the PCRF entity through the Spending-Notification-Request (SNR) message, instructing it to recalculate the bandwidth and A Re-Authentication Request (RAR) message is sent to the PCEF for bandwidth control re-authentication.

Under the existing technical solution, if a package is shared to a user in a group, if a user's use or subscription trigger in the group reaches the condition that the bandwidth policy needs to be changed, the OCS needs to use the group. Each user in the middle sends an Expiration Notification SNR message to the PCRF entity. Then, the PCRF entity sends a RAR message to the PCEF entity for each user in the group, which causes a large increase in the SNR request message and the RAR message, resulting in a large occupation of system resources.

detailed description

The embodiment of the invention provides a method for bandwidth control, which can reduce the number of notification messages between the OCS and the PCRF when the bandwidth usage policy of the group user changes, thereby improving the utilization of system resources. The embodiments of the present invention also provide corresponding devices and systems. The details are described below separately.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

Referring to FIG. 1, an embodiment of a traffic monitoring system according to an embodiment of the present invention includes: an online charging system OCS, a policy and charging execution function PCEF entity, and a policy and charging rule function PCRF entity, and a PCRF entity and an OCS are adopted. The Sy interface communicates between the PCEF entity and the PCRF entity through the Gx interface. The PCEF entity communicates with the OCS through the Gy interface. When the user uses the data service, the PCEF entity first applies for the available bandwidth to the PCRF through the Gx interface; the PCRF passes the Sy. The interface obtains a bandwidth reference factor from the OCS, such as a counter-count and a counter-level, and calculates a bandwidth that the user can use, for example, 2 Mbps or 1 Mbps, and then The user-usable bandwidth is returned to the PCEF entity. The PCEF entity allocates bandwidth to the user according to the bandwidth that the user can use. In addition, the PCEF entity reports the charging request to the OCS to complete the reservation and deduction of the cost through the Gy interface.

In the embodiment of the present invention, the notification message may be a payment notification request (Spending-Notification-Request, SNR) message, the first notification message may be an SNR message, and the second notification message may be a re-authentication request (RAR) ) message. Of course, the SNR message and the RAR message may be other notification messages in the existing protocol, which are not specifically limited in the embodiment of the present invention. In the following multiple embodiments, the notification message is an SNR message, the first notification message is an SNR message, and the second notification message is an RAR message.

The group in the embodiment of the present invention may be a group user, for example, an enterprise user.

The bandwidth for the users in the group may change the usage of the bandwidth due to the change in the total amount of traffic usage. For example, if a company has a total of 1000 people, the corporate legal person A applies for 100G to the telecom operator. The traffic is used every month for the daily work of the employees. But in order to prevent To exceed the total usage of the business, it is required to reduce the bandwidth after the total usage of the traffic reaches 80% this month. Before the total usage of the traffic reaches 80% this month, the bandwidth is 2Mbps. When the total usage of the traffic reaches 80% this month. After that, when the remaining 20G, the bandwidth becomes 1Mbps. After exhaustion, the operator can provide free but lower bandwidth 512kbps for employees in the enterprise.

After the employee B0 consumes, the total consumption reaches 80G, that is, the threshold of 80% is reached. The bandwidth of the employee B0 needs to be modified, and the bandwidth of all other online employees needs to be modified. Assuming all online employees (B0, B1, B2, B3, ... Bn) are 800, OCS needs to send payment notifications to the PCRF entity for all online employees (B0, B1, B2, B3, ... Bn) 800 people. Requesting a (Spending-Notification-Request, SNR) message, and then sending a Re-Authentication Request (RAR) message to the PCEF entity by the PCRF entity for all online employees (B0, B1, B2, B3, ... Bn) Then, the PCEF entity modifies the bandwidth of all online employees.

In the embodiment of the present invention, the method for delivering the SNR message and the RAR message in the scenario of the group user can be understood as:

In the solution of the present invention, the identifier of the online user in the extended parameter group is added in the SNR/RAR message, and the identifier of the online user in the group is used to uniquely identify the user terminal under the shared counter. The shared counter means that the users in the group share a Counter-ID, and the identifier of the online user in the group may be a session identifier (SessionID), a mobile subscriber international number (Mobile Subscriber International ISDN/PSTN number, MSISDN), and an international mobile subscriber identity code. (International Mobile Subscriber Identification Number, IMSI), etc., when the SNR message is sent, the OCS can notify the PCRF entity by sending the identifier of the online user in the group, or the PCRF can also send the RAR message to the PCEF entity in the RAR message. The identifier of the online user in the group is carried, so that the PCRF entity determines the bandwidth usage of all online users in the group when determining the bandwidth usage policy, and the PCEF entity updates all online users in the group when updating the bandwidth policy. Information. This ensures that the SNR message and the RAR message between the PCRF and the OCS and the PCEF and the PCRF are reduced. The SNR message and the RAR message are not required to be sent to each user in the group, thereby greatly reducing the SNR message and the RAR message, and improving the utilization of system resources. In particular, the utilization of network bandwidth resources and CPU resources is improved.

The process of the method for bandwidth control can be understood by referring to FIG. 2, which is a schematic diagram of an embodiment of a method for bandwidth control:

S100 and the PCEF entity report a charging control request (CCR) to the OCS. The amount of traffic that can be carried in a CCR message.

S105. The OCS deducts the fee according to the usage of the traffic, and reserves, and calculates a new CounterLevel of the CounterID.

S110. Return a Accounting Control Acknowledge (CCA) message to the PCEF.

In the embodiment of the present invention, the CounterID is a bandwidth.

S115. If the CounterLevel calculated in step S105 is changed, and the group of the group is a shared counter, it is necessary to find the SessionID of all other users sharing the Counter, and then send an SNR message to the PCRF. At the same time, the SNR request carries the SessionID of other users.

When the S120 and the PCRF perform the bandwidth control policy, the bandwidth policy of the current user is not only executed, but also the bandwidth decision of other users is required.

S125. The PCRF sends a Payment Notification Acknowledge (SNA) message to the OCS after the decision.

S130. The PCRF needs to instruct the PCEF to perform bandwidth control after the decision, and the PCRF sends a RAR request to the PCEF for the same bandwidth usage policy caused by the same SNR request, and carries the SessionID of all online users in the RAR. The corresponding bandwidth.

S135. The PCEF performs the indication of the PCRF, and not only needs to execute the wide usage policy rule of the current session, but also needs to extract the associated SessionID to update the wide usage policy of other online users in the group.

All online users in the group use the new bandwidth to access the Internet.

S140: A PCEF Re-Authentication Acknowledge (RAA) message is sent to the PCRF.

In the embodiment of the present invention, for a scenario of a group user, an SNR message and an RAR message are not required to be sent to each user in the group, thereby greatly reducing SNR messages and RAR messages, and improving system resources. Utilization rate.

In addition, when the OC message is sent to the PCRF by the OCS, the SNR message is not limited to only one SNR message. The session ID of the online user in the group may be divided into groups according to the number of online users in the group, and then the SNR corresponding to the number of packets is sent. For example, when a group has 800 people online, you can divide the SessionID of 800 online users into 8 groups, each group has 100 SessionIDs, then the OCS only needs to send 8 SNR messages, thus avoiding SNR messages. Large, causing problems with transmission anomalies.

In the embodiment of the present invention, the message parameter extension is concentrated on the SNR message of the Sy interface and the RAR cancellation of the Gx. The SNR message and the RAR message respectively extend the parameter of the online user's identity in the group. For this parameter, the processing logic on each network element side is defined as follows:

The application logic on the OCS side may include the following steps for the extension of step S115, as shown in FIG. 3:

S115-1. When the SessionID0 of the session is initiated, the CounterLevel is changed. The OCS checks whether the package of the group to which the user belongs is a shared counter. When it is the shared counter, step S115-2 is performed. When the Counter is shared, step S115-7 is performed.

S115-2: Query the session identifiers (SessionID1 to SessionIDn) of other online users sharing the Counter.

Of course, the embodiment of the present invention is not limited to the SessionID, and may also be an MSISDN or an IMSI.

S115-3: It is confirmed whether the number of SessionIDs of all online users is greater than 1. If it is greater than 1, step S115-4 is performed, and if it is not greater than 1, step S115-7 is performed.

S115-4: Determine whether the number of SessionIDs of all online users is greater than N. If it is greater than N, perform step S115-5. If it is not greater than N, perform step S115-6.

S115-5, in units of N, splits the number of all online SessionIDs into multiple groups.

For example, when N=100, 800 SessionIDs are placed in 8 SNR requests in units of 100.

In fact, it can also be understood that in the unit of N-1, in addition to setting a primary SessionID in each SNR, N-1 associated SessionIDs are set. In fact, the principle in N is the same as above.

S115-6: Set N SessionIDs in each SNR message.

S115-7. Send an SNR request to the PCRF.

In the prior art, if the usage or subscription trigger of a user in the group reaches the condition that the bandwidth policy needs to be changed, then an SNR message needs to be sent to the PCRF entity for each user in the group, resulting in an SNR message. Compared with a large amount of increase, the method for bandwidth control provided by the embodiment of the present invention can reduce the number of SNR messages between the OCS and the PCRF when the bandwidth usage policy of the group user changes, thereby improving the utilization of system resources.

After the PCRF receives the SNR request, the application logic on the PCRF side may include the following steps for the extension of step S120, as shown in FIG. 4:

S120-1. Determine a bandwidth usage policy of the SessionID0 corresponding to the changed CounterLevel according to the CounterID of the SessionID 0 and the changed CounterLevel.

S120-2. Analyze the number of SessionIDs in the SNR. When the SessionID is greater than 1, perform steps. S120-3, if it is not greater than 1, step S125 is performed.

S120-3, determining a corresponding bandwidth usage policy for the SessionID other than the SessionID0.

The bandwidth usage policy may include a quality of service (QoS), that is, a value of available bandwidth.

After the PCRF sends the SNA response, the processing logic for the identification of all online users in the group when transmitting the RAR message to the PCEF is as shown in FIG. 5 for the extension of step S130:

S130-1 and the PCRF obtain the bandwidth usage policy of all the SessionIDs.

S130-2. Determine whether only one session session needs to be updated this time. If there is not only one, step S130-3 is performed, and if only one needs to be updated, step S130-8 is performed.

S130-3. Divide the same bandwidth usage policy into the same packet.

S130-4: Determine whether the number of SessionIDs in each group is greater than 1. If it is greater than 1, step S130-5 is performed, and if it is not greater than 1, step S130-8 is performed.

S130-5. Determine whether the number of SessionIDs in each packet is greater than N. If it is greater than N, perform step S130-6.

S130-6, in units of N, splits the number of all online SessionIDs into multiple groups.

S130-7: Set N SessionIDs and corresponding bandwidth usage policies in each RAR message.

S130-8. Send a RAR message to the PCEF.

In the prior art, if the usage or subscription trigger of a user in the group reaches the condition that the bandwidth policy needs to be changed, then a RAR message needs to be sent to the PCEF entity for each user in the group, resulting in a RAR message. Compared with a large amount of increase, the method for bandwidth control provided by the embodiment of the present invention can reduce the number of RAR messages between the PCRF and the PCEF when the bandwidth usage policy of the group user changes, thereby improving the utilization of system resources.

After the PCEF receives the RAR request, the processing logic for all online users in the group is extended for step S135, as shown in FIG. 6:

S135-1. Perform a bandwidth usage policy of the session (SessionID0).

S135-2. Analyze the number of SessionIDs in the RAR. When the SessionID is greater than 1, step S135-3 is performed. If it is not greater than 1, step S140 is performed.

S135-3. The corresponding bandwidth usage policy is also replaced for the SessionID other than the SessionID0.

S140: A PCEF Re-Authentication Acknowledge (RAA) message is sent to the PCRF.

Referring to FIG. 7A, a method for bandwidth control provided by an embodiment of the present invention includes:

The S200 and the PCEF entity report a charging control request (CCR) to the OCS, and the CCR message can carry the usage of the traffic.
