Description

Application-based policy and charging control method and device, storage medium

Technical field

The present invention relates to the field of communications, and in particular to an application-based policy and charging control method and apparatus, and a storage medium.

Background technique

FIG. 1 is a schematic diagram of a Policy and Charging Control (PCC) architecture defined by the 3rd Generation Partnership Project (3GPP) in the related art, as shown in FIG. 1 , a policy and a charging rule function. The Policy and Charging Rules Function (PCRF) is used to formulate quality of service (QoS) and charging policies for services using network resources. The PCRF needs to combine the service information received from the Application Function (AF), the user subscription information received from the User Profile Repository (SPR), and the policy configured by the operator. The PCRF sends the control policy for the service to the Policy and Charging Enforcement Function (PCEF) or the Bearer Binding and Event Report Function (BBERF). At the same time, the PCRF can subscribe to the bearer layer related events to the PCEF and/or the BBERF to sense in time when the bearer layer occurs, and change the control strategy. In addition, the PCEF and the Traffic Detection Function (TDF) can perform application detection and control functions according to PCC rules or Application and Detection Control (ADC) rules issued by the PCRF.

In order to achieve end-to-end QoS guarantee, the 3GPP network provides QoS guarantee based on bearer granularity. Services that are mapped to the same bearer will be forwarded using the same bearer layer packet. If different bearer layer packet forwarding processing needs to be provided, the service flow needs to be mapped to different evolved packets. The core network carries the Evolved Packet System (EPS) bearer. Generally, a bearer has an associated traffic flow template (TFT). The uplink traffic flow template (UL TFT) is a set of uplink packet filters in the TFT. The downlink traffic flow template (DL TFT) is a downlink packet filter set in the TFT. One host is allowed to have no TFTs in each Public Data Network (PDN) connection. For an EPS IP-Connectivity Access Network (IP-CAN), the default bearer may not have a TFT.

The PCC or QoS rule delivered by the PCRF includes a service data flow template (SDF template). The SDF template usually includes one or more service data flow filters. The PCRF can provide a PCC rule containing a wild-carded traffic stream filter to allow packets that cannot match any other PCC or QoS rules to pass.

After the PCEF or BBERF installs or activates the PCC rules or QoS rules provided by the PCRF, the PCEF or the BBERF performs bearer binding according to the QCI/ARP in the rule, and constructs the TFT according to the SDF template in the rule to be sent to the user equipment (User Equipment, UE). Although the same QCI/ARP rules can be bound to the same bearer, not the same QCI/ARP rules are always bound to the same bearer. Therefore, the PCRF cannot determine which bearer the rule is bound to when providing the PCC rule/QoS rule, and the PCEF/BBERF finally decides to bind the PCC/QoS rule to a specific bearer.

For the GBR bearer, the PCEF/BBERF sets the bearer's GBR to the sum of the GBRs bound to all the PCC rules or QoS rules of this bearer, and sets the bearer's MBR as the MBR bound to all PCC rules or QoS rules of this bearer. Sum. For Non-GBR bearers, when the IP-CAN type supports non-GBR bearers with separate MBRs, the MBRs carried by the Non-GBR are set to the sum of the MBRs bound to all PCC rules or QoS rules of this bearer. The core network and the radio side will allocate corresponding resources for the bearers according to QCI, ARP, GBR, and MRB.

Therefore, the existing QoS guarantee mechanism requires the network or terminal to identify a service data packet according to the packet filter, thereby applying corresponding QoS to the identified data packet. However, this method has the following problems: 1) For different service data streams of the same application, although they have the same QoS, because there are different service filters, interaction between the network and the termination is required for the network. The UE can be informed of the uplink QoS of the traffic data stream, thereby generating unnecessary signaling. 2) When the terminal runs a type of application that is non-deducible (that is, a stable service filter cannot be obtained), such as peer-to-peer (P2P) service, the network cannot filter the service and bear the service. The binding relationship is notified to the terminal, so the terminal cannot be informed of the uplink QoS parameters of such applications. The current processing of such applications is to put them on the default bearer.

In the related art, the problem of the uplink bearer cannot be effectively notified to the UE, and there is currently no effective solution.

The bearer binding and event reporting function BBERF receives the quality of service QoS rule sent by the policy and charging rule function PCRF, wherein the QoS rule carries the application identifier and the QoS parameter;

The BBERF executes the QoS rule to initiate a process of reserving resources for the application.
The method of claim 11, wherein the BBERF executes the QoS rule, initiates a process of reserving resources for the application, and the method further includes:

The BBERF sends a create or modify bearer request message to the UE, where the create or modify bearer request message carries the application identifier and the QoS parameter.
The method according to claim 11, wherein before the BBERF receives the QoS rule sent by the PCRF, the method further includes:

Receiving, by the BBERF, a fourth resource reservation request message sent by the user equipment UE, where the fourth resource reservation request message carries an application identifier and a QoS request parameter;

The BBERF sends a QoS rule request message to the PCRF, where the QoS rule request message carries the application identifier and the QoS request parameter.
