The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, device, and computer storage medium for service quality control.

Background technique

Referring to FIG. 1 , FIG. 1 is a network architecture diagram of a NextGen network system. Based on the network architecture diagram, the process of determining service quality control information is: a Policy Control Function (PCF) to process a service data flow. The policy control and charging (PCC) rule of the service data flow (SDF) level is sent to a session management function (SMF), where the PCC rule includes quality of service (QoS). The SMF binds different PCC rules according to the QoS parameters. The PCC rules with the same QoS requirements are bound to the same QoS flow, and the QoS flow ID (QFI) is assigned to the bound QoS flows. The SMF sends the bound QoS flow and the QFI to the access network (AN). When the AN receives the service data stream sent by the User Plane Function (UPF), the SQoS is based on the received QoS flow. The QFI is transmitted to the user equipment (User Equipment, UE) by using the radio bearer with the corresponding quality of service, so as to ensure that the service data obtains the corresponding service quality to meet the delay requirement of the service data. In Figure 1, N1-N4, N7, and N11 are all air interface resources.

The delay requirement of the existing service is generally in the range of 100ms-300ms, and the requirements for air interface resource scheduling are low. The current NextGen network determines the QoS flow through the above process, and the scheduling air interface resource transmission service data can meet the delay requirement of the service data. The NextGen network system adds support for Ultra-Reliable and Low Latency Communications (URLLC) services. The delay requirement of the URLLC service is shorter, generally in the range of 5ms-20ms, which has higher requirements for air interface resource scheduling, that is, only the air interface resource having the transmission capability in the range of 5ms-20ms can implement the URLLC service. The URLLC service generally has a Guaranteed Bit Rate (GBR) transmission requirement. For a data packet whose code rate is smaller than the GBR range, the network system must ensure the QoS requirements of the transmission data packet, for example, the transmission delay requirement must be met. .

If the QoS flow is determined according to the QoS requirements according to the foregoing procedure, the determined QoS flow may cause the air interface to fail to implement the QoS requirement for the QoS flow, thereby causing the network to fail to support the transmission of the URLLC service data.

Detailed ways

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.

The delay requirement of the existing service is generally in the range of 100ms-300ms, and the requirements for air interface resource scheduling are low. The current NextGen network determines the QoS flow through QoS requirements, and the scheduled air interface resource transmission service data can meet the delay requirement of the service data. The NextGen network system adds support for URLLC (Ultra-Reliable and Low Latency Communications) services. The delay requirement of the URLLC service is shorter, generally in the range of 5ms-20ms. This has higher requirements for air interface resource scheduling, that is, only the air interface resource with the transmission capability in the range of 5ms-20ms can implement the URLLC service. If the QoS flow is determined only according to the QoS requirement, the determined QoS flow may cause the air interface to fail to implement the QoS requirement for the QoS flow, thereby causing the network to fail to support the transmission of the URLLC service data.

In view of this, an embodiment of the present invention provides a method for quality of service control, in which a PCC rule sent by a PCF to an SMF may indicate an air interface transmission capability, so that the SMF may have an air interface transmission capability indicated by the PCC rule. The service data flow corresponding to the PCC rule of the same QoS requirement is bound to one or more QoS flows, and the sum of the GBRs of the PCC rules bound to the same QoS flow does not exceed the air interface transmission capability. The SMF sends control information of one or more QoS flows to the AN, so that the AN can perform radio resource scheduling for guaranteeing the quality of the data stream transmission service for the at least one QoS flow according to the control information of the one or more QoS flows. That is, the SMF not only considers the QoS requirements, but also binds the service data flow corresponding to the PCC rule to the QoS flow according to the air interface transmission capability, so that the air interface can implement the QoS requirement for the QoS flow, and can better support the transmission of the URLLC service data. .

The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

Referring to FIG. 2, a method for service quality control according to an embodiment of the present invention is applicable to the network architecture shown in FIG. 1, and the process of the method is described as follows.

S201: The PCF sends a PCC rule to the SMF, where the PCC rule includes a QoS requirement and a GBR requirement for the service data flow, and the PCC rule further indicates an air interface transmission capability.

In the embodiment of the present invention, when a service needs to be performed, the UPF receives the service data stream, and sends the received service data stream to the AN, so that the AN sends the service data stream to the UE. Before the UPF receives the service data stream, the PCF sends the PCC rule corresponding to the service to be performed to the SMF, where the PCC rule includes the QoS requirement and the GBR requirement for the service data flow, so that the SMF will receive the PCC rule. Bind to a QoS flow that can provide the corresponding QoS guarantee. In a 5G network, QoS flow can be understood as the minimum granularity of QoS control in order to ensure the quality of data transmission. All data in the same QoS flow accepts the same data transmission processing and radio resource scheduling. The SMF sends the control information of the QoS flow to the UPF and the AN respectively. Therefore, the UPF transmits the service data stream to the AN according to the received QoS stream, and the AN performs the radio resource scheduling for ensuring the quality of the data stream transmission for the received QoS stream, and implements the transmission of the received service data stream to the UE.

For the URLLC service, the required transmission delay is low, generally in the range of 5ms-20ms, which has higher requirements for air interface resource scheduling, that is, only air interface resources with transmission capacity in the range of 5ms-20ms. In order to implement the URLLC service. Therefore, in the embodiment of the present invention, the PCC rule may also indicate the air interface transmission capability, so that the SMF binds the PCC rule in consideration of the air interface transmission capability, so that the obtained QoS flow considers the air interface transmission capability, thereby making the AN for the URLLC. The service can perform radio resource scheduling to ensure the quality of the data stream transmission service.

S202: The SMF binds the service data flow corresponding to the PCC rule with the same QoS requirement to the at least one QoS flow according to the QoS requirement, the GBR requirement, and the air interface transmission capability, where the sum of the GBRs of the PCC rules bound to the same QoS flow is Does not exceed the air interface transmission capacity.

The PCF may send a PCC rule to the SMF, or may send at least two PCC rules to the SMF. If the PCF sends a PCC rule to the SMF, that is, the SMF only receives one PCC rule, the SMF can bind the service data flow corresponding to the PCC rule to a QoS flow according to the QoS requirement, the GBR requirement, and the air interface transmission capability. Multiple QoS flows, as long as the sum of the GBRs of the PCC rules bound to the same QoS flow does not exceed the air interface transmission capability, so that the AN can perform the radio resource scheduling for ensuring the quality of the data stream transmission for the received QoS flows, and realize the transmission. Quality of service for business data streams.

If the SMF receives at least two PCC rules, it may determine PCC rules having the same QoS requirements among the at least two received PCC rules. Specifically, in the embodiment of the present invention, the QoS requirement may include a 5G QoS indicator (5QI). If the 5QIs in the two PCC rules are the same, the two PCC rules may be considered to have the same QoS requirement. In a possible implementation manner, the QoS requirement may also include Allocation and Retention Priority (ARP) information. If the 5QIs in the two PCC rules are the same and the ARPs are the same, the two PCC rules may be considered to have the same QoS. Claim.

After the SMF determines the PCC rules with the same QoS requirements, the air interface transmission capability needs to be considered before binding the service data flows corresponding to the PCC rules with the same QoS requirements, so that the GBRs of the PCC rules bound to the same QoS flow are obtained. The sum does not exceed the air interface transmission capability. The air interface transmission capability can be understood as the transmission delay allowed by the air interface, the quality of service capability to be transmitted by the air interface, or the maximum amount of data allowed to be transmitted within a specified time. In the embodiment of the present invention, the air interface transmission capability is a Maximum Data Burst Volume (MDBV) that the air interface can transmit according to the 5QI requirement in a specific time window.

Among them, the specific time window can be the following:

The first type: the specific time window is a preset transmission delay. For example, the network system presets a transmission delay, for example, 5ms-10ms.

The second type: the specific time window is the transmission delay corresponding to the 5QI, that is, the transmission delay indicated by the 5QI, that is, the transmission delay indicated by the 5QI carried in the PCC rule.

The third type: the specific time window is the transmission delay sent by the PCF, and the PCF sends the PCC rule, and may also separately send a signaling, which carries the transmission delay, for example, 7ms-10ms.

After the SMF determines the PCC rules with the same QoS requirements, the air interface transmission capability needs to be considered before binding the service data flows corresponding to the PCC rules with the same QoS requirements, so that the GBRs of the PCC rules bound to the same QoS flow are obtained. The sum does not exceed the air interface transmission capability.

Specifically, the SMF first determines the air interface transmission capability indicated by the PCC rule. Possible implementations include at least the following three cases (the following is an example of monitoring the transmission delay of the 5QI based on the specific time window of the MDBV):

The first case: the value of the 5QI included in the PCC rule sent by the PCF is a standardized value, that is, the standard value specified by the industry in the 5QI, as shown in Table 1 below.

Table 1

5QI5QI	传输时延Transmission delay	MDBVMDBV
1010	5ms5ms	160B160B
1111	10ms10ms	320B320B
1212	20ms20ms	640B640B

Then, according to the value of 5QI and the mapping relationship between 5QI and MDBV shown in Table 1, the SMF can obtain the value of MDBV, that is, determine the air interface transmission capability. For example, if the value of 5QI is 10, then the SMF can determine that the air interface transmission capability is 160B for the maximum transmission data volume within 5ms. In the first case, the value of the 5QI included in the PCC rule sent by the PCF may be a standard value as specified in Table 1, so that the PCF may not send the MDBV to the SMF, and the value of the default MDBV of the SMF may be the value of the 5QI. The value of the corresponding MDBV. Therefore, the PCF can indicate the air interface transmission capability by the value of the standardized MDBV pointed to by the 5QI.

For different operators, the value of 5QI may be other pre-configured values. For example, for a mobile operator, the value of the pre-configured 5QI is 13, and the value of the corresponding MDBV may be 320B. Although the value of the 5QI is not within the standard value range as shown in Table 1, the mobile operator network Each network element knows that when the value of 5QI is 13, the corresponding value of MDBV is 320B. For this case, the value of the 5QI in the PCC rule may be a pre-configured value of the operator, and the value of the corresponding MDBV may be determined as long as the SMF determines which operator. In this case, the value of the pre-configured MDBV that the PCF can also point to through the 5QI is only the air interface transmission capability.

The PCF may send a correspondence between the value of the 5QI and the value of the MDBV to the SMF before sending the PCC rule to the SMF, so that after the SMF determines the value of the 5QI, the correspondence between the value of the 5QI and the value of the MDBV is determined. Determine the value of MDBV. Alternatively, the PCF may also send the correspondence between the value of the 5QI and the value of the MDBV and the PCC rule to the SMF through a signaling.

The second case: the value of the 5QI included in the PCC rule sent by the PCF is a standardized value, that is, the value of the standard as shown in Table 1 specified by the 5QI in the industry, and the PCC rule sent by the PCF carries the preset value. The value of MDBV. In this case, even if the value of the 5QI is determined to be a standardized value, the SMF does not determine the value of the MDBV corresponding to the 5QI as the air interface transmission capability, but determines the value of the preset MDBV sent by the PCF as Air interface transmission capability.

In the third case, the value of the 5QI included in the PCC rule sent by the PCF is a non-standardized value. At the same time, the PCC rule sent by the PCF carries the value of the preset MDBV. In this case, the SMF determines the value of the preset MDBV sent by the PCF as the air interface transmission capability.

In the second case and the third case, the PCF indicates the air interface transmission capability by using the preset value of the MDBV, and the SMF needs to determine the QoS parameter corresponding to the 5QI, such as the transmission delay, in addition to determining the air interface indication capability. At this time, the PCF may send a QoS parameter corresponding to the 5QI to the SMF before sending the PCC rule to the SMF, for example, a specific transmission delay and/or a correspondence between the value of the 5QI and the value of the MDBV, so that the SMF determines. After the value of the 5QI is determined, the value of the specific transmission delay and/or the MDBV is determined by the correspondence between the value of the 5QI and the value of the MDBV. Alternatively, the PCF may also send the corresponding QoS parameters of the 5QI and the PCC rules to the SMF through a signaling. The embodiment of the present invention is not limited to the manner in which the PCF sends the QoS parameter corresponding to the 5QI.

The PCF can indicate the air interface transmission capability by any of the above three cases. After the SMF determines the air interface transmission capability, the service data flow corresponding to the PCC rule having the same QoS requirement is bound to the at least one QoS flow in combination with the QoS requirement and the GBR requirement, and is bound to the GBR of the PCC rule of the same QoS flow. And does not exceed the air interface transmission capacity.

Specifically, if the sum of the GBRs of the PCC rules having the same QoS requirement is that the amount of data corresponding to the specific time window for monitoring the MBDV does not exceed MBDV, the PCC rules having the same QoS requirement are bound to the same QoS flow, otherwise The PCC rules with the same QoS requirements are bound to multiple QoS flows, and the sum of the GBRs of the PCC rules of each QoS flow after binding does not exceed the air interface transmission capability.

For the sake of understanding, the following describes how the SMF binds the service data flow corresponding to the PCC rule with the same QoS requirement to at least one QoS flow according to the QoS requirement, the GBR requirement, and the air interface transmission capability, and binds to the same QoS. The sum of the GBRs of the flow PCC rules does not exceed the air interface transmission capability.

For example, if the 5QI included in the PCC rule corresponding to a service data flow (SDF) is 10, 10 is the value normalized in Table 1, the transmission delay of transmitting the service data stream may be considered to be no more than 5 ms. The air interface can transmit up to 160B of data in a specific time window, that is, 5ms. The specific time window for monitoring the MDBV generally takes the delay corresponding to the transmission delay, which is 5ms. Suppose the SMF receives three PCC rules corresponding to three SDFs. The 5QIs of the three PCC rules are all 10, and the ARPs of the three PCC rules are also the same, that is, the three PCC rules have the same QoS requirements. Among them, the GBR of each PCC rule is set to 100 kb/s, because the GBR of each SDF has an average amount of data of 5 ms (GBR/1000/8)*5, that is, 64B. If these three PCC rules are bound to one QoS flow, the amount of data bound to this QoS flow is 64B*3, which is 192B, which is obviously larger than the air interface transmission capability, that is, 160B. Therefore, only the service data flows corresponding to the two PCC rules can be bound to the same QoS flow, and the service data flow corresponding to another PCC rule needs to establish a separate QoS flow, so that the data volume of each QoS flow can be made. The ability to not exceed the amount of data that an air interface can transmit.

S203: After the SMF binds the at least one QoS flow, the SMF sends the control information of the at least one QoS flow to the access network AN, where the control information is used to perform radio resource scheduling for guaranteeing the quality of the data stream transmission for the at least one QoS flow. .

Specifically, after the SMF is bound to the at least one QoS flow, each QoS flow may be assigned a QoS flow ID (QFI). The SMF will be the QFI and the QoS parameters of each QoS flow, which can also be understood as the control information of each QoS flow, and control the at least one QoS flow through the Access and Mobility Management Function (AMF). Information is sent to the AN. The control information of each QoS flow includes a 5QI and a Guaranteed Flow Bit Rate (GFBR) of each QoS flow. The 5QI of each QoS flow is the 5QI of the PCC rule bound to each QoS flow, and the GFBR of each QoS flow is the sum of the GBRs of the PCC rules bound to each QoS flow.

The SMF may also send the packet filtering information and the corresponding QFI included in all the PCC rules bound to each QoS flow to the UPF, so that after receiving the downlink data, the UPF uses the filter to match the IP header of the received downlink data. Corresponding QFI is applied to the matched data packet, and the service data packet is sent to the AN through an air interface, for example, an air interface N3 channel. The AN sends the radio bearer to the UE using the corresponding quality of service according to the QFI, so as to ensure that the data packet obtains the corresponding quality of service.

In the embodiment of the present invention, in order to facilitate the description of the entire process, the method performed by the PCF and the SMF is described for the flow shown in FIG. 2, but it is necessary to know that both the PCF and the SMF can independently execute the corresponding method steps. .

The technical solution of the service quality control provided by the embodiment of the present invention is introduced in the following specific embodiments.

Embodiment 1

For a URLLC type service data flow, the PCF formulates a PCC rule corresponding to the service data flow according to the service requirement and the operator policy, and sends the PCC rule to the SMF. The PCC rules sent by the PCF to the SMF include 5QI, ARP, and/or GBR information, where the 5QI is a standardized or pre-agreed value, such as a value agreed in advance for each operator. In this way, the SMF can determine, according to the value of the 5QI, the specific transmission delay corresponding to each 5QI and the maximum amount of data MDBV that can be transmitted in the specific time window for the air interface required for the transmission delay. Alternatively, the PCF may not use the value of the standardized or pre-configured MDBV, but instead carry a new MDBV value in the PCC rule to cover the standardized or pre-configured MDBV value, so that the SMF determines the MDBV carried by the PCC rule. The value is the air interface transmission capability.

Then, the SMF binds the service data flow corresponding to the PCC rule of the same 5QI and ARP to the same QoS flow according to the 5QI and ARP included in the PCC rule, and the SMF also considers the GBR of the PCC rule bound to the same QoS flow. The sum cannot exceed the required air interface transmission capability of the 5QI. For example, the sum of the GBRs is allocated to the specific time window for monitoring the MBDV, and the value of the MBDV cannot be exceeded. Otherwise, even the PCC rules of the same QoS requirement cannot be aggregated. In a QoS flow, a new QoS flow is established for transmission. The SMF assigns a QoS Flow Identity QFI to each QoS Flow and combines the GBRs in the PCC rules bound to the same QoS Flow as the GFBR of the QoS Flow.

The SMF sends the QFI of the one or more QoS flows and the packet filtering information contained in the PCC rules bound to each QoS flow according to the binding result, that is, the control information of the QoS flow to the UPF, and the UPF uses the downlink data according to the UPF. The packet filter filters to the corresponding QoS flow for transmission.

The SMF sends the QFI of the one or more QoS flows and the corresponding packet filtering information, that is, the control information of the QoS flow, to the UE, and the UE uses the AMF to filter the uplink data according to the packet filter to the corresponding QoS flow for transmission.

The SMF sends the QFI of the one or more QoS flows and the corresponding QoS requirements, that is, the control information of the QoS flow, to the AN through the AMF, and the AN ensures the transmission of each QoS flow according to the QoS requirement.

Embodiment 2

This example differs from the first embodiment in that the PCF defines a non-standardized 5QI and sends the QoS parameters corresponding to each 5QI to the SMF. The QoS parameters corresponding to the 5QI include, for example, a specific transmission delay and a maximum amount of data MDBV that the air interface required for this transmission delay can transmit in a specific time window. The QoS parameters corresponding to each 5QI are sent by the PCF to the SMF in the sending PCC rule, or merged into the PCC rule, and sent to the SMF through a signaling.

The SMF binds the service data flow corresponding to the received PCC rule to at least the QoS flow, and allocates a flow identifier for each QoS flow, and sends the QFI of the established one or more QoS flows and the corresponding packet filtering information to the UE. The QFI of the one or more QoS flows and the corresponding QoS requirements, that is, the QoS flow control information, are sent to the AN. For details, refer to the first embodiment, and details are not described herein again.

In summary, in the method for quality of service control provided by the embodiment of the present invention, the PCC rule sent by the PCF to the SMF may indicate the air interface transmission capability, so that the SMF may have the same QoS requirement according to the air interface transmission capability indicated by the PCC rule. The service data flow corresponding to the PCC rule is bound to one or more QoS flows, and the sum of the GBRs of the PCC rules bound to the same QoS flow does not exceed the air interface transmission capability. The SMF sends control information of one or more QoS flows to the AN, so that the AN can perform radio resource scheduling for guaranteeing the quality of the data stream transmission service for the at least one QoS flow according to the control information of the one or more QoS flows. That is, the SMF not only considers the QoS requirements, but also binds the PCC rules to the QoS flows according to the air interface transmission capability, so that the air interface can implement the QoS requirements for the QoS flows, and can better support the transmission of the URLLC service data. That is, the embodiment of the present invention solves the problem that the QoS requirement of the 5G network for the high-latency-sensitive URLLC service is supported, so that the network can formulate the QoS requirement according to the service requirement and the air interface transmission capability, and ensure that the QoS requirement of the QoS flow can be obtained in the air interface. Execute effectively, thus ensuring efficient transmission and support of the network for high latency sensitive URLLC services.
