Description

QoS flow control method and communication device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a QoS flow control method and a communications apparatus.

Background

In a fifth Generation mobile communication (5Generation, 5G) system, in order to guarantee end-to-end quality of service of a service, a 5G QoS model based on quality of service (QoS) flow (flow) is proposed, and the 5G QoS model includes a Guaranteed Bit Rate (GBR) QoS flow (GBR) of a Guaranteed Bit Rate (GBR) and an unsecured bit rate (NGBR QoS flow (Non-GBR QoS flow).

In the prior art, when the network device detects that the QoS rate of GBR QoS flow cannot be satisfied, the network device may be notified by a "notification control" message. The core network can reallocate the GBR rate for the GBR QoS flow so as to prevent the GBR QoS flow from occupying the frequency spectrum resources all the time and causing unnecessary waste.

Generally, after receiving a notification control message from the network side, the core network reconfigures the GBR rate of the GBR QoS flow according to a fixed configuration policy. However, if the GBR rate of GBR QoS flow reallocation is too low, the customer experience will be affected; if the GBR rate of GBR flow reconfiguration is too high, when the GBR rate after GBR QoS flow reconfiguration does not meet the requirement, the network side still continues to report the notification control message. Therefore, how to flexibly configure the GBR rate of the GBR QoS flow becomes an urgent problem to be solved.

Detailed Description

Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application are explained:

network slicing: the method is a mode of networking on demand newly introduced under the 5G standard, a communication operator can separate a plurality of virtual end-to-end networks on a unified communication infrastructure, and each network slice can be logically isolated on a wireless access network, a bearer network and a core network so as to adapt to various types of services. The network device may establish multiple network slices for a terminal device according to the service requirements.

The basic granularity of a network slice is Protocol Data Unit (PDU) Session (Session), and one network slice of a terminal device may contain 1 or more PDU sessions. One PDU Session may contain multiple QoS flows. The terminal device and the network device may perform data transmission on the QoS flow. For example, as shown in fig. 1, a network slice between a network device and a terminal device may include network slice 1 and network slice 2. Network slice 1 includes PDU Session1 and PDU Session 2. PDU Session1 includes QoS flow1 and QoS flow 2. PDU Session2 includes QoS flow 3. Network slice 1 includes PDU Session 3. PDU Session3 includes QoS flow 4.

It should be noted that each of the multiple network slices of the same terminal device may have corresponding radio resources, that is, the radio resources corresponding to different network slices are different. The plurality of network slices may share the same radio resource, without limitation. For example, network slice 1 in fig. 1 corresponds to radio resource 1, and network slice 2 corresponds to radio resource 2. Alternatively, the radio resources corresponding to network slice 1 and network slice 2 are the same. The radio resources may include time domain resources, frequency domain resources, channel resources, and the like. Without limitation.

Quality of service (QoS): the method is a safety mechanism of a communication network, and can be used for solving the problems of network delay, network congestion and the like. The communication network can ensure the communication quality of users through the QoS technology. For example, the core network device may make QoS parameters and QoS policies according to subscription information of a client or preset policies, and the network device may implement and guarantee the QoS policies according to the QoS parameters. The terminal device may match the QoS flow with the data packet of the uplink user plane according to the QoS policy indication, and send the data packet of the uplink user plane to the network device using the matched QoS flow and a corresponding channel or Resource Block (RB).

QoS flow: the QoS Flow may be classified into GBR QoS Flow and Non-GBR QoS Flow according to QoS profile (profile). The QoS parameters for QoS profile may include one or more of the following parameters: a 5G QoS identifier (5G QoS identity document, 5QI), an Allocation and Retention Priority (ARP). Wherein the Non GBR QoS Flow may contain Reflective QoS Attributes (RQA). The GBR QoS Flow may include one or more of a Guaranteed Flow Bit Rate (GFBR), a Maximum Flow Bit Rate (MFBR), a notification control, a maximum packet loss rate (applicable only to voice traffic).

The terminal device performs classification and marking of the uplink user plane data service, that is, the terminal device can associate the uplink user plane data with the corresponding QoS flow according to the QoS rule, and send the uplink user plane data to the network side by using the QoS flow. These QoS rules may be explicitly provided to the terminal device (i.e., configured to the terminal device through signaling display in the PDU session setup/modification procedure), or may be preconfigured for the terminal device, or may be implicitly derived for the terminal device using a reflective QoS mechanism.

It should be noted that, in this embodiment of the present application, the network device may establish QoS flow of a corresponding network slice according to a service type of the terminal device. For example, if the service type of the terminal device is a service requiring GBR rate guarantee, the network device may establish GBR QoS flow for the terminal device, and the GBR rate of the GBR QoS flow is the GBR rate corresponding to the service. Of course, the network device may also pre-establish multiple QoS flows. For example, the plurality of QoS flows may include at least one GBR QoS flow and at least one NGBR QoS flow. And the network equipment selects proper QoS flow from the plurality of QoS flows according to the service type of the terminal equipment. Without limitation.

When the network device detects that the QoS rate of GBR QoS flow can not be satisfied, the network device can inform the core network device through an inform control message. The core network may choose to reconfigure the GBR rate for the GBR QoS flow, for example, the GBR rate configuration of the GBR QoS flow may be reduced, or the GBR QoS flow may be directly deleted, so as to prevent the GBR QoS flow from always occupying the spectrum resources and causing unnecessary waste.

After the core network device receives the notification control message from the network side, the core network can reconfigure the GBR rate of the GBR QoS flow according to a fixed configuration strategy. However, if the GBR rate of GBR QoS flow reallocation is too low, the customer experience will be affected; if the GBR rate of GBR flow reconfiguration is too high, when the GBR rate after GBR QoS flow reconfiguration does not meet the requirement, the network side still continues to report the notification control message.

In order to solve the problem, an embodiment of the present application provides a method for controlling a QoS flow, where the method includes: the core network device receives a first notification message from the network device, where the first notification message includes resource configuration information of a target network slice, the first notification message is used to indicate that a data transmission rate of a first QoS flow is less than a guaranteed bit rate GBR rate, the target network slice is a network slice in which the number of GBR QoS flows in the network slice configured by the network device is greater than a preset value, and the first QoS flow is a GBR QoS flow that satisfies a first preset condition among a plurality of GBR QoS flows of the target network slice. And the core network equipment adjusts the GBR rate of the first QoS flow according to the resource configuration information of the target network slice.

In the method provided by the embodiment of the present application, the core network device receives the data transmission rate, which is used for indicating that the first QoS flow is received from the network device, and is less than the GBR rate, that is, the GBR rate of the first QoS flow cannot be satisfied. The core network device may adjust the GBR rate of the first QoS flow according to the resource configuration information of the network slice corresponding to the first QoS flow. Since the resource configuration information of the network slice may be used to characterize the current available resources of the network slice, the core network device may flexibly adjust the GBR rate of the first QoS flow according to the current available resources of the network slice.

Fig. 4 provides a method for controlling QoS flows according to an embodiment of the present application, and as shown in fig. 4, the method includes:

step 401, the network device detects a data transmission rate of a first QoS flow of a target network slice.

Wherein the network device may be the network device 220 in fig. 2. The target network slice may be a plurality of network slices configured for the terminal device, including network slices in which the number of GBR QoS flows is greater than a preset value. The preset value may be set as desired, for example, the preset value may be 2. Without limitation. The terminal device may be any of the terminal devices in fig. 2. For example, the terminal device 1 or the terminal device 2 in fig. 2 may be used, without limitation.

Wherein the first QoS flow may be a GBR QoS flow satisfying a first preset condition among a plurality of GBR QoS flows of the target network slice. The first preset condition may include one or more of a priority, a GBR rate. For example, the first QoS flow may be a GBR QoS flow having a priority less than a preset level and/or a GBR rate greater than a preset rate. The GBR QoS flow priority and GBR rate may be preset and are not limited. The first preset condition is only an example, and may further include other conditions, such as the number or quality of the radio resources occupied by the GBR QoS flow, and the like, without limitation.

In an example, the network device may periodically or randomly detect the data transmission rate of the first QoS flow, or the network device may detect the data transmission rate of the first QoS flow when data is transmitted or received through the first QoS flow, which is not described in detail herein.

Step 402, if the data transmission rate of the first QoS flow is less than the GBR rate, the network device sends a first notification message to the core network device. Accordingly, the core network device receives the first notification message from the network device.

The core network device may be the core network device 210 in fig. 2.

The first notification message may be used to indicate that the data transmission rate of the first QoS flow cannot be met, or to indicate that the data transmission rate of the first QoS flow is lower than the GBR rate. The GBR rate of the first QoS flow is preset according to the need, and is not limited.

Wherein the first notification information may be used to represent/indicate/include resource configuration information of the target network slice. The resource configuration information of the target network slice may be used to characterize the resource usage of the target network slice. For example, the resource configuration information may include one or more of the following parameters: a slice multiplexing index or indication (slice multiplex indication) of the target network slice, a slice edge rate (slice margin rate) of the target network slice, a current data transmission rate (not bit rate) of the first QoS flow of the target network slice. These three parameters are explained below:

1. slice multiplexing index of the target network slice. The slice multiplexing index of the target network slice refers to the number of network slices using the first radio resource. The first radio resource is a radio resource used by the target network slice. For example, if the slice multiplexing index of the target network slice is 1, it indicates that the number of network slices using the first radio resource is 1, that is, the target network slice; if the slice multiplexing index of the target network slice is 2, it indicates that the number of network slices using the first radio resource is 2, that is, the network slices using the first radio resource further include a network slice other than the target network slice; if the slice multiplexing index of the target network slice is 3, it indicates that the number of network slices using the first radio resource is 3, that is, the network slice using the first radio resource further includes two network slices other than the target network slice.

2. Slice edge rate of target network slices. The slice edge rate of the target network slice may be used to characterize the current data transmission rate margin. The current data transmission rate margin of the target network slice may be determined according to the current data transmission rate of the target network slice, the data transmission rates of the plurality of GBR services carried by the target network slice, and the data transmission rates of the plurality of NGNR services.

For example, the current data transmission rate margin of the target network slice may be a difference between the current data transmission rate of the target network slice and a sum of QoS flow configured data transmission rates of a plurality of services carried by the target network slice.

The current data transmission rate of the target network slice may be the sum of current data transmission rates of a plurality of services carried by the target network slice. For example, it may be the sum of the current data transfer rates of multiple GBR QoS flows and the current data transfer rates of multiple NGBR QoS flows.

The plurality of services may include GBR services and NGBR services, among others. For example, the GBR QoS flow configured data transmission rate for GBR traffic may be the GBR rate configured for the GBR QoS flow. The NGBR QoS flow configured data transfer rate of the NGBR service may be the NGBR QoS flow configured data transfer rate. The data transmission rate configured by the NGBR QoS flow may be configured in advance according to needs, for example, may be determined according to the type of the NGBR service or subscription information of the terminal device using the NGBR service, or may be allocated to the NGBR service by the network device according to the use condition of the network, without limitation.

In one example, the network device may determine the slice edge rate of the target network slice according to an air interface environment where the target network slice is currently located and a current data transmission rate margin. The air interface environment where the target network slice is currently located may refer to the network quality where the target network slice is currently located, for example, may refer to channel quality or signal quality.

For example, the network device may determine the slice edge rate of the target network slice according to equation one below.

Wherein smr represents a slice edge rate of the target network slice, R represents a current data transmission rate of the target network slice, BR represents a data transmission rate of QoS flow of a plurality of services carried by the target network slice, and p represents a ratio of a number of first services to a number of the plurality of services carried by the target network slice. The first service is a service of the plurality of services, wherein the network quality meets a preset threshold value.

For example, a service of the plurality of services whose network quality is greater than a first preset value is a first class service (which may also be referred to as a best-effort service). The service with the network quality less than or equal to the first preset value and greater than the second preset value is a second grade service (also called a midpoint service). The service with the network quality greater than or equal to the second preset value in the plurality of services is a third grade service (also called a difference point service). Wherein the first preset value is larger than the second preset value. For example, the number of the plurality of services carried by the target network slice is N, the number of the services of the first level is N1, the number of the services of the second level is N2, and the number of the services of the third level is N3. Then p is N1/N, or p is N2/N, or p is N3/N.

The network device may determine p according to the quality of the network where the target network slice is currently located. For example, if the network quality at which the target network slice is currently located is greater than the first threshold, p is N1/N, smr is (R-BR) × (N1/N). If the network quality of the target network slice is smaller than or equal to the first threshold and larger than the second threshold, p is N2/N, smr is (R-BR) × (N2/N). If the network quality of the target network slice is smaller than or equal to the second threshold, p is N3/N, smr is (R-BR) × (N3/N). Wherein the first threshold is greater than the second threshold. The first threshold and the second threshold may be set as needed, without limitation.

It should be noted that the method for dividing the service classes and the method for selecting p are merely exemplary, and other dividing methods are also available, for example, the service classes may be divided into more than 3 classes, for example, into 5 classes. Alternatively, the traffic may be classified into less than 3 classes, e.g., into 3 classes. Without limitation.

3. The current data transmission rate of the first QoS flow of the target network slice may refer to a transmission rate of data carried by the first QoS flow. For example, if the data carried by the first QoS flow is uplink data, the current data transmission rate of the first QoS flow is a transmission rate at which the terminal device sends data to the network device using the first QoS flow. If the data carried by the first QoS flow is downlink data, the current data transmission rate of the first QoS flow is a transmission rate at which the network device sends data to the terminal device using the first QoS flow.

Step 403, the core network device processes the first QoS flow according to the resource configuration information of the target network slice.

The core network device may determine resource configuration information of the target network slice according to the first notification message.

For example, the first notification message may include M flags, one of the M flags corresponding to one of M parameters, and the M services include one or more of the three parameters. When the first notification message comprises a flag bit, the core network equipment determines that the resource configuration information of the target network slice comprises a parameter corresponding to the flag bit; when the first notification message does not include one flag bit, the core network device determines that the resource configuration information of the target network slice does not include a parameter corresponding to one flag bit. Wherein M is an integer greater than or equal to 1.

The flag bit may be a symbol or a number, or a combination of a symbol and a number, without limitation.

For example, the flag bit corresponding to the slice multiplexing index of the target network slice is SMI, the flag bit corresponding to the slice edge rate of the target network slice is SMR, and the flag bit corresponding to the current data transmission rate of the first QoS flow of the target network slice is NBT. When the first notification message comprises 'SMI', the core network equipment determines that the resource configuration information of the target network slice comprises a slice multiplexing index; when the first notification message comprises 'SMR', the core network equipment determines that the resource configuration information of the target network slice comprises a slice edge rate; when the first notification message includes "NBT", the core network device determines that the resource configuration information of the target network slice includes a slice edge rate. Furthermore, the core network device may determine a value of a parameter corresponding to one flag bit according to a value corresponding to one flag bit. For example, if the first notification message includes "SMI-2", the core network device may determine that the value corresponding to the flag "SMI" is 2, that is, the slice multiplexing index of the target network slice is 2.

For yet another example, the first notification message may be a clear text indication. For example, the first notification message may be as shown in table 1.

TABLE 1

It should be noted that, in table 1, if the critical value of a certain parameter is ignore (ignore), that is, if the setting of the parameter exceeds the critical value, the parameter will not be effective; if the threshold is reject, then the parameter cannot be set to an out-of-range value at the time of setting. For the slice margin rate, slice multiplex index and not bit rate in Table 1, refer to the above description. For the description of other parameters in table 1, please refer to the prior art, which is not repeated.

In a possible implementation manner, the core network device may adjust the first QoS flow according to whether the number of times that the data transmission rate of the first QoS flow is less than the GBR is less than or equal to a preset number of times and the configuration information of the target network slice.

For example, if the number of times that the data transmission rate of the first QoS flow is less than the GBR rate is less than or equal to the preset number of times, the core network device adjusts the GBR rate of the first QoS flow according to one or more of the slice multiplexing index of the target network slice, the slice edge rate of the target network slice, and the current data transmission rate of the first QoS flow; if the number of times that the data transmission rate of the first QoS flow is smaller than the GBR rate is larger than the preset number of times, the core network equipment judges whether to adjust the service borne by the first QoS flow and the GBR rate of the first QoS flow according to the resource configuration information of the first network slice.

Specifically, the method for the core network device to adjust the first QoS flow according to whether the number of times that the data transmission rate of the first QoS flow is less than the GBR is less than or equal to the preset number of times and the configuration information of the target network slice is described in detail below.

Based on the technical solution of fig. 4, the core network device receives the data transmission rate indicating that the first QoS flow is lower than the GBR rate from the network device, that is, the GBR rate of the first QoS flow cannot be satisfied. The core network device may adjust the GBR rate of the first QoS flow according to the resource configuration information of the network slice corresponding to the first QoS flow. Since the resource configuration information of the network slice may be used to characterize the current available resources of the network slice, the core network device may flexibly adjust the GBR rate of the first QoS flow according to the current available resources of the network slice.

In a possible implementation manner, before step 401, the method for controlling a QoS flow provided in this embodiment of the present application may further include: the core network device determines a target network slice and a first QoS flow.

Specifically, the target network slice and the first QoS flow may refer to the description in step 401, and are not described in detail.

For example, the core network device may detect each network slice in the network device according to a preset period, determine a target network slice according to the number of GBR flows of the network slice, and select a first QoS flow from a plurality of GBR flows of the target network slice according to the priority and GBR rate of the GBR flows of the target network slice. Further, the core network device enables the first QoS flow to have a "notification control" function.

The "notification control" function means that if the GBR rate of the first QoS flow cannot be satisfied, the network device may actively send a first notification message to the core network device, so that the core network device may process the first QoS flow.

Based on the possible implementation mode, the core network device can select a part of QoS flows to have notification control, and the data transmission rate of the target network slice is monitored through the part of QoS flows, so that the signaling overhead is reduced.

In another possible implementation manner, as shown in fig. 5, step 403 in fig. 4 may be implemented by steps 4031 to 4040 as follows:

step 4031, the core network device detects whether the number of times that the data transmission rate of the first QoS flow of the target network slice is lower than the GBR rate is lower than a preset value.

The fact that the data transmission rate of the first QoS flow is lower than the GBR rate may mean that the current data transmission rate of the first QoS flow is lower than a preset GBR rate, or the data transmission rate of the first QoS flow is lower than the adjusted GBR rate. The preset value may be set as desired, and may be 1, for example.

For example, if the preset value is 1, step 4031 may be described as the core network device determining/detecting whether the first notification message is received for the first time. The first notification message may refer to the above description.

It should be noted that, if the number of times that the data transmission rate of the first QoS flow of the target network slice is lower than the GBR rate is lower than the preset value, the core network device executes step 4032; if the number of times that the data transmission rate of the first QoS flow of the target network slice is lower than the GBR rate is higher than or equal to the preset value, the core network device performs steps 4033 to 4040.

Step 4032, the core network device deletes the first QoS flow.

The core network device may directly send the first QoS flow, or may assign another GBR QoS flow to the traffic carried by the first QoS flow before or after deleting the first QoS flow, or may reestablish a GBR QoS flow for the traffic carried by the first QoS flow. For example, the specified/newly-established GBR QoS flow may be a slice of a public network, or may be another slice of a network configured for the terminal device of the service, without limitation.

Step 4033, the core network device determines whether the ratio of the slice edge rate of the target network slice to the slice multiplexing index is greater than the GBR rate.

The slice edge rate and slice multiplexing index of the target network slice may be referred to above.

It should be noted that, if the ratio of the slice edge rate of the target network slice to the slice multiplexing index is greater than the GBR rate, the core network device executes step 4034; if the ratio of the slice edge rate of the target network slice to the slice multiplexing index is less than or equal to the GBR rate, the core network device performs steps 4035 to 4040.

Step 4034, the core network device adjusts the GBR rate of the first QoS flow, and the adjusted GBR rate is the current data transmission rate of the first QoS flow.

Adjusting the GBR rate of the first QoS flow by the core network device may also be described as reconfiguring the GBR rate of the first QoS flow by the core network device. For example, the core network device may use the current data transmission rate of the first QoS flow as the adjusted GBR rate. As such, the adjusted GBR rate may satisfy the GBR rate of the first QoS flow.

The core network device may also adjust the GBR rate of the first QoS flow according to a preset instruction. For example, the core network device may use a difference between a current data transmission rate of the first QoS flow and a preset rate as the adjusted GBR rate of the first QoS flow. The preset rate can be set according to the requirement, and is not limited.

In this way, the core network device may ensure that the adjusted GBR rate of the first QoS flow is less than the current data transmission rate, and in some cases, for example, the current data transmission rate of the first QoS flow is V1, and after the time t elapses, the data transmission rate of the first QoS flow is V2, where V1- Δ V < V2 < V1, and Δ V is a preset rate. At this time, the GBR rate of the first QoS flow may still be satisfied, so that the network device may not send the first notification message to the core network device, thereby reducing signaling overhead.

Step 4035, the core network device checks whether the terminal device has other network slices.

The terminal device may refer to the related description in step 401.

Whether the terminal device has other network slices refers to whether the terminal device has network slices other than the target network slice. For example, if the terminal device is the terminal device 1 in fig. 2 and the target network slice is the network slice 1, it is described that the terminal device further has the network slice 2, that is, the terminal device has another network slice. If the terminal device is the terminal device 2 in fig. 2 and the target network slice is the network slice 3, it indicates that the terminal device does not have other network slices.

It should be noted that, if the terminal device does not have other network slices, the core network device executes step 4036; if the terminal device has other network slices, the core network device executes steps 4038 to 4039.

Step 4306, the core network device detects whether a ratio of a slice edge rate of the target network slice to a slice multiplexing index is greater than a preset threshold.

The slice edge rate and the slice multiplexing index of the target network slice may refer to the above description. The preset threshold can be set according to needs and is not limited.

It should be noted that, if the ratio of the slice edge rate of the target network slice to the slice multiplexing index is greater than the preset threshold, the core network device executes step 4037; if the ratio of the slice edge rate of the target network slice to the slice multiplexing index is less than or equal to the preset threshold, the core network device executes step 4032.

Step 4037, the core network device adjusts the GBR rate of the first QoS flow, and the adjusted GBR rate is the ratio of the slice edge rate of the target network slice to the slice composite index.

Step 4038, the core network device determines a first network slice.

The first network slice is a network slice which is except for the target network slice and meets a second preset condition in a plurality of network slices configured by the terminal equipment. The second preset condition may be for selecting the first network slice from a plurality of network slices configured by the terminal device.

For example, the second preset condition may include a ratio of a slice edge rate to a slice composite index, and a number of NGBR QoS flows included by the network slice. For example, the first network slice may be a network slice with a largest ratio of slice edge rate to slice composite index and a largest number of NGBR QoS flows.

Step 4039, the core network device determines whether the ratio of the slice edge rate of the first network slice to the slice composite index is greater than the ratio of the slice edge rate of the target network slice to the slice composite index.

If yes, the core network device executes step 4040; if the number is smaller than or equal to the number, the core network device executes step 4036.

Step 4040, the core network device reestablishes the service carried by the first QoS flow to the first network slice.

The step of re-establishing the traffic carried by the first QoS flow to the first network slice refers to using the GBR QoS flow of the first network slice to carry the traffic carried by the first QoS flow, or using the GBR QoS flow of the first network slice to transmit data of the traffic carried by the first QoS flow.

Based on the method, if the ratio of the slice edge rate of the target network slice to the slice composite index is less than or equal to the GBR rate, it is indicated that the first QoS flow of the target network slice cannot meet the GBR rate of the bearer service. In this case, the core network device may bear the service through other network slices, so as to ensure normal use of the service and improve user experience.
