Description

Data flow distribution method and related equipment

Technical Field

The present application relates to the field of communications, and in particular, to a data traffic distribution method and related devices.

Background

For enterprise users, the broadband network is mainly used for office business and has the characteristics of large user quantity and large flow. A network operator wants to add a plurality of users to a group by pushing out a group sharing service, so that the users in the group can share and use a certain service and a traffic quota of the service. Thus, under the condition that the group traffic quota is fixed, the users with large traffic consumption in the group can use the traffic of the users with small traffic consumption, thereby saving the cost for the group (enterprise or family) and helping the operator attract more users.

A Policy and Charging Rule control Function (PCRF) network element issues a fixed-size traffic fragment to all users through a Gx interface, and when a last traffic fragment of a shared traffic quota is issued, if the fixed-size traffic fragment is also continuously issued, the sum of traffic consumption of simultaneous use of multiple users is equal to the size of the traffic fragment, i.e., the fixed size of the traffic fragment is 10MB, and when the last traffic fragment is issued, the actual shared traffic quota is 55MB, and for 6 users, the sum of traffic consumption is 6 × 10MB, and a network operator loses 5MB of traffic revenue.

In order to reduce the traffic loss of a network operator, an existing data traffic distribution method is as follows: the PCRF network element indicates a Policy and Charging Enforcement Function (PCEF) network element to actively report the service condition of the traffic fragments at regular time, so as to avoid that the PCRF network element omits the traffic fragments which are already issued to the PCEF network element and the "in-transit" traffic which is not completely exhausted when allocating the traffic fragments to the user. And when the shared traffic quota configured by the PCRF network element reaches a predetermined threshold (90%) or the last traffic slice (the traffic balance is equal to the number of traffic slices and the number of online users), the reporting frequency of the use conditions of the traffic slices of all the users is reduced, thereby relieving the traffic calculation deviation caused by the use conditions of the traffic slices reported by a plurality of online users to a certain extent.

However, the existing data traffic distribution method only alleviates the traffic calculation deviation of the PCRF network element when multiple online users are present, and does not effectively solve the traffic loss existing during the last traffic fragmentation, so that the traffic loss of the network operator still exists.

Disclosure of Invention

The application provides a data traffic distribution method and related equipment, which are used for dynamically adjusting the size of a traffic fragment and reducing the traffic loss of a network operator.

A first aspect of the present application provides a data traffic distribution method, including:

when PCRF equipment detects the last first traffic fragment, the PCRF equipment issues a traffic reporting instruction to PCEF equipment, wherein the traffic reporting instruction is used for indicating the PCEF equipment to acquire first traffic information of an online user;

the PCRF equipment receives first traffic information of the online user fed back by the PCEF equipment;

the PCRF equipment obtains second traffic fragments according to the first traffic information, wherein the size of the second traffic fragments is smaller than that of the first traffic fragments, and the number of the second traffic fragments is at least two;

and the PCRF equipment sends the second traffic fragment to the PCEF equipment.

In the existing group traffic quota method based on the user group, the PCRF device configures at least two first traffic segments with fixed sizes according to the total traffic required by all online users in the user group, sends the first traffic segments to the PCEF device, the online users can obtain the data traffic required by the service through the first traffic segments provided by the PCEF device, and after each first traffic segment is used up, the PCEF device notifies the PCRF device, so that the PCRF device can definitely detect the last first traffic segment, when the PCRF device detects the last first traffic segment, the PCRF device issues a traffic reporting instruction to the PCEF device, the traffic reporting instruction specifically functions to enable the PCEF device to count out the first traffic information of all online users, the first traffic information can be the size of the traffic required by each user at present, the PCRF device obtains a second traffic segment according to the first traffic information, that is, the sum of the traffic required by all online users can be obtained according to the first traffic information, so as to configure at least one second traffic slice, where the size of the second traffic slice is smaller than that of the first traffic slice, and the second traffic slice is sent to the PCEF device, so as to provide the online users with the traffic service, because the size of the second traffic slice is smaller than that of the first traffic slice, the network operator can necessarily reduce traffic loss when providing the traffic service, for example, according to the existing method, it is assumed that the fixed size of the first traffic slice is 10MB, and when the last first traffic slice is the last, the actual required traffic of 6 users is 55MB, the sum of traffic consumption is 6 × 10MB, and the network operator loses 5MB of traffic, but according to the scheme of the present application, it is assumed that the fixed size of the first traffic slice is 10MB, and when the last first traffic slice is the first traffic slice, obtaining the first traffic information of 6 users (the traffic value is 55MB), then reconfiguring to obtain the second traffic slice, the size of the second traffic slice is smaller than 10MB, for example, 9.5MB, then the sum of the traffic consumption of the second traffic slice is 57MB, and compared with the prior art 60MB, the traffic loss of the network operator is reduced by 3 MB.

With reference to the first aspect of the present application, in a first implementation manner of the first aspect of the present application, the obtaining, by the PCRF device, the second traffic segment according to the first traffic information includes:

and the PCRF equipment adjusts the size of the first traffic fragments according to the first demand traffic value to obtain second traffic fragments, wherein the size of the second traffic fragments is smaller than that of the first traffic fragments, and the number of the second traffic fragments is at least one.

Since the PCEF device counts all online users to obtain the first traffic information before the last first traffic segment begins, the first demand traffic value of the online users can be determined according to the first traffic information, the first demand traffic value is the actual demand traffic of the currently performed traffic slice, the fragmentation policy is adjusted according to the first demand traffic value, that is, the size of the first traffic fragment is reduced to obtain the second traffic slice, and the second traffic slice is at least two, for example, the size of the first traffic slice is 10MB, the number of the online users is 6, when the first demand traffic value is 55MB, if the size of the second traffic slice is between 55/6MB and 10MB, the second traffic slice is one, if the size of the second traffic slice is between 55/12MB and 55/6MB, the second traffic slice is two, and so on.

Detailed Description

The technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application.

First, a system architecture or scenario in which the present application is applied will be briefly described.

Third generation partnership project (3)^rdGeneration Partnership Project, 3GPP) introduces a PCRF network element structure in a network from the R7 version, which can control Quality of Service (QoS) of users and traffic states, provide differentiated services for users, and provide traffic flow bearer resource guarantee and a traffic flow charging policy for users, thereby really enabling a network operator to realize a more refined traffic control and charging manner based on traffic and user classification, so as to reasonably utilize network resources, create maximum profits, and provide reliable guarantee for Packet Services (PS) domain to develop multimedia real-time services. The PCRF device contains policy control decisions and flow-based charging control functions. The PCRF device accepts input from other devices in a Policy Control and Charging (PCC) architecture, and makes a PCC decision in combination with its own custom information.

The PCC architecture is shown in fig. 1, where the PCEF mainly includes the detection of traffic data flows, policy enforcement, and flow-based charging functions. The functional entity can be positioned in the gateway equipment or can be independently deployed; an Application Function (AF) entity is an application service providing unit and is mainly used for carrying out dynamic policy/charging control on IP-CAN user plane behaviors, and the AF transmits dynamic session information required by the PCRF through an Rx reference point and receives specific information of the IP-CAN and confirmation of an IP-CAN bearing layer event; an Online Charging System (OCS) provides a credit control function based on a user and a service data stream, mainly comprises modules such as Online acquisition, Charging control, rating, balance management and the like, realizes an Online Charging function, and is matched with other Charging network element devices (for example, an Online Charging event request device based on a session or an event is triggered) to perform real-time traffic control; an Offline Charging System (OFCS) provides a Charging function based on user and service data flow, and the main functions include customer service, service management, Charging, settlement, account processing, System management, and the like, and is a post-payment processing System for telephone bills and accounts; a user attribute Storage (SPR) entity contains information related to all subscribers or subscriptions; a Bearer Binding and Event Report Function (BBERF) is a policy enforcement point for bearer Binding, uplink bearer Binding verification, and Event reporting to the PCRF when Gxx exists, and the functional entity is located in a gateway, for example, based on an S5/S8 interface, and implements a serving gateway (S-GW) for 3GPP access using PMIP (proxy mobile IP); the Traffic Detection Function (TDF) performs application detection and reports that the detected application and its service data traffic description are directed to the PCRF, and if the TDF cannot detect these information, the TDF performs gating, redirection and bandwidth limitation, and if the application information can be detected, the TDF submits a decision to the PCRF to perform control. Sp, Rx, Sy, Sd, Gxx, Gx, Gy, and Gz in FIG. 1 are reference points between the connection of the various components.

Fig. 2 is a signaling processing flow of common traffic accumulation in a PCEF and a PCRF, where, in step 1, a User initiates a request for establishing an IP-CAN session to the PCEF through User Equipment (UE), where the User is a group User, has multiple users, and may share one traffic segment; step 2, the PCEF sends a CCR-Initial message to the PCRF through a Gx interface; step 3, the PCRF finds out the service data of the user according to the user identification, and then generates a QoS rule, a flow fragment, a service rule list, a trigger and the like according to the service data; step 4, the PCRF returns information such as traffic fragments, a service rule list, a trigger and the like to the PCEF through a CCA-Initial message; step 5, the PCEF installs rules according to the CCA-Initial message and returns an IP-CAN session response message to the user; step 6, after the user flow fragmentation is exhausted, the PCEF sends a CCR-Update message to the PCRF; step 7, the PCRF performs quota deduction according to the usage of the traffic fragments and updates the strategy according to the service definition; and 8, the PCRF sends the updating strategy to the PCEF through the CCA-Update message, so that the PCEF deletes the original rule and installs the new rule.
