Description

Resource adjustment method, device and storage medium of GBR service based on QoS

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a storage medium for resource adjustment of GBR service based on QoS.

Background

In the network, quality of service (Quality of Service, qoS) flows can be divided into guaranteed bit rate (Guaranteed Bit Rate, GBR) QoS flows and Non-GBR QoS (Non-GBR QoS) flows. The service using GBR QoS to flow and transmit data is guaranteed bandwidth service, and the service using Non-GBR QoS to flow and transmit data is Non-guaranteed bandwidth service. In a network, whether GBR QoS flows or Non-GBR QoS flows are transmitted, corresponding resources, such as radio resources of an air interface, need to be configured.

However, when multiple GBR users and Non-GBR users coexist in the same cell, in order to guarantee the guaranteed bandwidth service of the GBR users, the base station reserves resources for the GBR users and allows the GBR users to preempt the resources of the Non-GBR users, thereby causing starvation of the resources of the Non-GBR users and being unfavorable for the overall operation of operators.

The following is a description of the terms/terms referred to in the embodiments of the present application, for convenience of the reader.

1. The 5G network slice divides the physical network into a plurality of logic virtual networks, and gives different SLAs (Service-Level Agreement) to the logic networks, thereby realizing the function of providing customized network services for clients by the network slice.

The network slicing technology divides a physical network into a plurality of virtual private networks, and each virtual private network can provide different network capacities, so that the differentiated network requirements are met, and meanwhile, the management of an industrial user group is simplified.

In network slicing, end-to-end traffic control is achieved by means of slice identification (single network slice selection assistance information: single Network Slice Selection Assistance Information, S-nsai) consisting of service type (Slice Service Type, SST) and slice subdivision (slice Differentiator, SD), which are unique in the terminal, radio network and core network. Wherein SST is 8 bits in length to indicate slice type, wherein 0-127 is defined by the standard and 128-255 is custom by the operator.

Currently 3GPP defines five standard SST values for eMBB, uRLLC, MIoT, V X and HMTC, as shown in Table 1 below. The SD length is 24 bits, and slices in the same SST, such as tenant information, are subdivided. The SD value is customized by an operator, who can formulate the SD value according to specific requirements of the 5G SA public network and the 5G SA industry network for the cut-off/service.

TABLE 1

Slice/service type	SST value	Characteristics of
			eMBB	1	Slice suitable for processing 5G enhanced mobile broadband
URLLC	2	Slice suitable for processing ultra-reliable low-delay communications
			MIoT	3	Slice suitable for processing of mass Internet of things
V2X	4	Slice suitable for processing V2X services
			HMTC	5	Slice suitable for processing high performance machine type communication

The network slicing technology is an end-to-end technology and penetrates three major domains of wireless, transmission and core in a network. At the wireless end, common slicing techniques include two techniques of Resource Block (RB) Resource reservation and QoS priority scheduling, where:

RB resource reservation slice technique implements radio resource provisioning and isolation through radio resource management (Radio Resource Management, RRM) policies and protection mechanisms. There are three types of resources defined in the standard that can be used for the guaranteed reservation of the slice users, namely physical resource block (Physical Resource Block, PRB) resources, data radio bearer (Data Radio Bearer, DRB) usage and radio resource control (Radio Resource Control, RRC) connected user number, wherein the slice users are defined by public land mobile network (Public Land Mobile Network, PLMN) identity and S-nsai, and the plurality of S-nsais form a slice group.

Currently, domestic operators generally adopt a radio resource management (Radio Resource Management, RRM) strategy to perform radio resource isolation guarantee on PRB resources.

In the standard protocol, when different subcarrier intervals are used, the same carrier width can be divided into different numbers of RBs, PRB (physical resource block) resource wireless resource isolation guarantee can be provided for a client by reserving a certain proportion of PRB resources for the client, and the RB division of an FR1 frequency band is shown in the following table 2, wherein the maximum transmission bandwidth of the FR1 is configured as N _RB ：

TABLE 2

2. QoS is a security mechanism of a communication network that can be used to solve problems such as network delay and congestion. The communication network can ensure the communication quality of the user through QoS technology. For example, the core network device may formulate QoS parameters and QoS policies according to subscription information of the client or preset policies, and the network device may implement and guarantee QoS policies according to the QoS parameters.

QoS flows can be classified into GBR QoS flows and Non-GBR QoS flows according to QoS configuration (profile). The QoS parameters of the QoS profile may include one or more of the following parameters: 5G QoS identifier (5G QoS identity document,5QI), allocation and retention priority (Allocation and Retention Priority, ARP). Among other things, the GBR QoS flows may include one or more of guaranteed flow bit rate (Guaranteed Flow Bit Rate, GFBR), maximum flow bit rate (Maximum Flow Bit Rate, MFBR), notification control, maximum packet loss rate (applicable only to voice traffic). MFBR (Maximum Flow Bit Rate) is the upper rate limit of GBR traffic, which is a non-guaranteed rate; GFBR is guaranteed bandwidth of GBR service, is bandwidth "permanently" allocated to subscribers by the network, and is not more than MFBR.

Non-GBR QoS flows may include Session-AMBR (per SessionAggregate Maximum Bit Rate), UE-AMBR (per UE AggregateMaximum Bit Rate) reflection QoS attributes (reflective QoS attribute, RQA). Wherein Session-AMBR limits the maximum bandwidth shared by all non-GBR QoS flows of one PDU Session and UE-AMBR limits the maximum bandwidth shared by all non-GBR QoS flows of one user.

If the service type of the terminal equipment is a service requiring GBR rate guarantee, the network equipment can establish GBR QoS flow for the terminal equipment, the GBR rate of the GBR QoS flow is GFBR corresponding to the service, and the maximum rate is MFBR.

Packets in the QoS flow that are within the GFBR committed rate are forwarded. The portion of data exceeding GFBR below MFBR and Non-GBR QoS flows are scheduled with weights, which are typically higher in the present network than Non-GBR QoS flows.

When GFBR guaranteed bandwidth in a GBR QoS flow cannot be guaranteed, the wireless base station may choose to send a notification to the session management function (Session Management Function, SMF) via Notification Control while continuing to keep the QoS flow functioning properly.

3. Shared resources (Shared resources): representing resources shared with other slice user groups (i.e., defining slice user groups in RRM Policy Ratio (RRM Policy Ratio) names). Shared resources are not guaranteed to be used by the associated slicing users. The shared resource quota is represented by [ RRM policy maximum ratio (RRM Policy Max Ratio) -RRM policy minimum ratio (RRM Policy Min Ratio) ].

Priority resource (Prioritized resources): meaning that the resources are preferentially used by the associated slice user group. These resources are guaranteed to be used by the associated slice user groups when needed. When not in use, these resources may be used by other slice user groups (i.e., slice user groups defined in the RRM Policy Ratio name). The priority resource quota is represented by [ RRM Policy Min Ratio-RRM policy specific proportion (RRM Policy Dedicated Ratio) ].

Dedicated resource (Dedicated resources): meaning that the resources are dedicated for use by the relevant slice user group. Even if the associated slicing users do not use these resources, they cannot be shared. The dedicated resource quota is denoted by [ RRM Policy Dedicated Ratio ].

The basic granularity of a network slice is a protocol data unit (Protocol Data Unit, PDU) Session (Session), and one network slice of one terminal device may contain 1 or more PDU sessions. One PDU Session may contain multiple QoS flows (Quality of service flow). The terminal device and the network device may perform data transmission on the QoS flow.

The following describes, through specific scenarios and embodiments, a resource adjustment method for a GBR service based on QoS provided in the embodiments of the present application.

Currently, resources are required to be reserved for GBR QoS flows in a network, and Non-GBR QoS flow services are not required; meanwhile, the resources of the GBR QoS flow are not preempted, while the resources of the Non-GBR QoS flow can be preempted by the GBR QoS flow. Therefore, a problem is brought, because most public network common users in the existing network transmit service through Non-GBR QoS flow, and when special VIP users excessively use GBR QoS flow to transmit service data, non-GBR QoS flow service resources of the common users are possibly excessively preempted, so that the use experience of the common users is reduced, and the overall operation of operators is not facilitated. In the 5G era, how to limit GBR QoS flow to occupy transmission resources excessively in network slicing, prevent special VIP users from occupying common user resources excessively, and balance resources of VIP clients and common users is a problem to be solved urgently.

It should be noted that, the user who uses GBR QoS to stream data is typically a VIP user (may become a GBR user) with high priority, and the user who uses Non-GBR QoS to stream data is typically a normal user (may be referred to as a Non-GBR user) with relatively low priority.

In order to solve the problem of how to limit the GBR QoS flow to excessively occupy transmission resources in a network and prevent a special VIP user from excessively occupying common user resources and balancing resources of VIP clients and common users in the prior art, the application provides a resource adjustment method of GBR service based on QoS, a base station can configure at least one slice user group for at least one type of GBR users in a cell, configure RRM strategy proportion for each slice user group, and adjust the RRM strategy proportion of the slice user group corresponding to the type of GBR users according to bandwidth parameters of the types of GBR users and user connection parameters of non-GBR users in the cell when the type of GBR users enter the cell. In the scheme, the GBR users are classified to a special slice configured with corresponding resource reservation proportion by a resource reservation hard slice technology in the network slice, and the radio resources of Non-GBR users are prevented from being excessively preempted by the GBR users by dynamically limiting the resource proportion which can be used by all GBR users in a cell, so that the use experience of the network users is improved, and the resource fairness among various users is balanced.

It should be noted that, herein, the RRM policy maximum ratio refers to RRM Policy Max Ratio, which defines the maximum resource usage quota of the slice user group. RRM policy minimum ratio is herein referred to as RRM Policy Min Ratio, defining the minimum resource usage quota for a slice user group. The RRM policy specific proportion herein refers to RRM Policy Dedicated Ratio, defining a specific resource usage quota for the slice user group. The specific description is given in the following examples, and will not be repeated here.

As shown in fig. 1, a flowchart of a resource adjustment method for a GBR service based on QoS according to an embodiment of the present application is provided, and the method includes the following steps S101 and S102:

s101, a base station configures at least one slice user group for at least one type of GBR users in a target cell, and configures RRM strategy proportion for each slice user group.

In this embodiment of the present application, the RRM policy proportion is used to characterize a resource usage quota of the slice user group.

It should be noted that, GBR users refer to 5G users in a 5G network that perform services through GBR QoS flows.

In one implementation, the RRM policy proportion includes at least one of: maximum proportion of RRM strategy, minimum proportion of RRM strategy and special proportion of RRM strategy.

The RRM strategy maximum proportion is used for representing the maximum resource use quota of the slice user group, the RRM strategy minimum proportion is used for representing the minimum resource use quota of the slice user group, and the RRM strategy special proportion is used for representing the special resource use quota of the slice user group.

In the embodiment of the present application, the 5G base station CELL (may be denoted as CELL _5G ) And configuring a plurality of slice user groups for GBR users (for example, the slice user group of the GBR users of class A is S-NSSAI=1-AXXXXX, the slice user group of the GBR users of class B is S-NSSAI=1-BXXXXX), configuring each slice user group as an RB resource reservation hard slice, and configuring the RB resource reservation through RRM strategy proportion. For example, the RRM policy maximum ratio of the class A slice user group is initially set

RRM policy maximum ratio of class B slice user group = max.b, rest, and so on.

It should be noted that, the RRM Policy limits the types and the number of resources used by RB resource slice users or user groups (slice users are defined by slice identifiers, and users of different slices may form a slice user group) through the RRM Policy Ratio (RRM Policy Ratio). Wherein:

the RRM policy maximum ratio (RRM Policy Max Ratio) attribute defines a maximum resource usage quota for the relevant slice user group, including at least one of shared resources, priority resources, and dedicated resources. For example, the sum of the "RRM policy maximum ratio" values for all slicing users may be greater than 100.

The RRM policy minimum ratio (RRM Policy Min Ratio) attribute defines a minimum resource usage quota for the associated slice user group, including at least one of a priority resource and a dedicated resource, i.e., a resource quota that needs to be guaranteed for use by the associated slice user group. For example, the sum of the "RRM strategy minimum ratio" values should be less than or equal to 100.

The RRM policy specific proportion (RRM Policy Dedicated Ratio) attribute defines the specific resource usage quota of the slice user group, including the specific resource. For example, the sum of the "RRM policy specific proportion" values should be less than or equal to 100.

S102, under the condition that the target GBR user enters the target cell, the base station adjusts the RRM strategy proportion of the slice user group corresponding to the target GBR user according to the bandwidth parameters of various GBR users in the target cell and the user connection parameters of the non-GBR user.

It can be appreciated that the base station (e.g., 5G base station) can set the RRM strategy proportion (e.g., RRM strategy maximum proportion, RRM strategy minimum proportion, RRM strategy dedicated proportion) of different slice user group PRB resource reservations, and the base station can be configured according to the base station CELL (CELL can be used _5G Representation) and user connection parameters of non-GBR users, dynamically adjusting the RRM policy proportion (e.g. RRM policy maximum proportion) of the sliced user group. It should be noted that, the adjustment range of the maximum proportion of the RRM strategy is 1-max (max is the maximum threshold value of the system after evaluation).

Illustratively, multiple classes of GBR protection classes of 5QI are defined in the standard, e.g., 5 qi=3, 5 qi=4, etc. GBR class a users (the number of users may be one or more) enter a target CELL (e.g., CELL) _5G ) GFBR (which may be denoted as GFBR) of GBR class a users (e.g. 5qi=4) _A ) Configured by the network as GFBR _A ＝G _A And the MFBR of the GBR class a user (may be denoted as MFBR _A ) Configured by the network as MFBR _A ＝M _A The target cell provides GBR service guarantee for the GBR user and lasts for a duration T1.

Note that, the Non-GBR user refers to a 5G user performing a service through an N0N-GBR QoS flow in the 5G network.

Multiple resource reservation network slice groups: the network is preset with a plurality of PRB resource reservation network slice user groups, all users using a GBR QoS stream are classified into one slice user group, and the slice ID can be set with a certain characteristic, for example, S-NSSAI=1-AXXXXX is classified into one slice user group at the beginning.

In one implementation, the bandwidth parameters include GFBR and MFBR.

In one implementation, the user connection parameters include an online number of non-GBR users, a PDU session number of the non-GBR users, and a maximum bandwidth of non-GBR data flows (Aggregate Maximum Bit Rate, AMBR) of all UEs in the target cell.

In the embodiment of the present application, the base station may count target CELLs (CELL) _5G ) The following Non-GBR user metrics, including but not limited to: non-GBR user online quantity C _user (i.e., number of users in RRC connected state), number of PDU sessions C of Non-GBR user _PDU UE-AMBR (per UE Aggregate Maximum Bit Rate) Total Bandwidth AMBR for all UEs in target cell _{Total (S)} ＝AMBR ₁ +AMBR ₂ +AMBR ₃ +. and the like.

In the embodiment of the application, an SMF network element receives a session establishment request initiated by UE and establishes a special QOS flow for the UE; the SMF network element transmits the PDR of the special QOS flow to the user plane function (User Plane Function, UPF) network element; the UPF network element receives and carries out service detection on the UE according to the PDR, and if the detected service accords with the PDR, the service event is reported to the SMF network element; and the SMF network element performs state switching on the GBR or Non GBR of the special QOS flow according to the service event reported by the UPF network element. According to the scheme, the UPF network element monitors service information of the UE in real time, the service use change condition of the UE is announced to the SMF network element, the SMF network element dynamically adjusts QOS flow attribute according to the received announcement information, and the QOS flow is adjusted to be GBR or Non GBR, so that the requirement that a client uses exclusive bandwidth is met, meanwhile, full and effective utilization of 5G network bandwidth resources is realized, and waste of bandwidth resources is avoided.

In one implementation manner, as shown in fig. 2 in conjunction with fig. 1, the above S102 may be specifically implemented by the following S102a and S102 b:

s102a, under the condition that the target GBR users enter the target cell, the base station calculates the total GFBR and the total MFBR of each GBR user in the target cell.

In the embodiment of the present application, the base station may count target CELLs (CELL) _5G ) Statistical indicators of various GBR users online include, but are not limited to: gBR for class A GBR users _A Total bandwidth GFBR _{A. Total (S)} ＝G _A 1+G _A 2+G _A 3+...+G _A n (n is the number of GBR users of class a), and MFBR _A The total bandwidth is MFBR _{A. Total (S)} ＝M _A 1+M _A 2+M _A 3+...+M _A n; GFBR for GBR class B users _B Total bandwidth GFBR _{B. Total (S)} ＝G _B 1+G _B 2+G _B 3+...+G _B m (m is the number of GBR users of class B), and MFBR _B The total bandwidth is MFBR _{B. Total (S)} ＝M _B 1+M _B 2+M _B 3+...+M _B m; …, and so on, until the total GFBR and the total MFBR for all GBR-like users in the target cell are counted.

S102b, the base station adjusts the RRM strategy proportion of the slice user group corresponding to the target GBR users according to the total GFBR and the total MFBR of each GBR user, and at least one first weight and the weight of the user connection parameter.

In this embodiment of the present application, the at least one first weight is a weight set for a total GFBR and a total MFBR of each type of GBR user.

In this embodiment of the present application, the base station may adjust RB resource reservation ratio of a slice user group corresponding to each type of GBR in the target cell to RRM policy maximum ratio=x, where x=gfbr, where the total GFBR and total MFBR of each type of GBR user in the target cell and user connection parameters of non-GBR users _{A.

Here set the weight _Non-GBR The interval is taken to avoid frequent adjustment of RRM policy proportion (such as RRM policy maximum proportion) caused by rapid change of the number of common users and PDU session number under the cell.

Weighting of _A.G Weight of _A.M Weight of _B.G Weight of _B.M Weight of _Non-GBR These values, constant N and constant M, threshold ₁ To the threshold value _k (k is the number of GBR users) and the like are flexibly set according to a base station user wireless resource scheduling algorithm.

In the embodiment of the application, the total amount of resources which can be used by the GBR user in the base station cell is limited by a hard slice reserved for RB resources, so that the GBR user is prevented from excessively occupying Non-GBR user resources. And, when setting the maximum available resource (RRM policy maximum ratio) of the RB resource reservation hard slice, besides the guaranteed bandwidth GFBR and the maximum bandwidth MFBR of the GBR user, the indexes of the user connection parameters related to the Non-GBR user, such as RRC online connection number, PDU session number and AMBR of the Non-GBR data stream of the UE, are also considered. The base station dynamically adjusts the value of the RRM strategy proportion (such as the maximum proportion of the RRM strategy) through the indexes, so that the use experience of Non-GBR users is not reduced while the GBR user experience is ensured to the maximum extent, and the resource fairness between the GBR service flow users and the Non-GBR service flow users is balanced.

The embodiment of the application provides a resource adjustment method of GBR service based on QoS, a base station can configure at least one slice user group for at least one type of GBR users in a cell, configure RRM strategy proportion for each slice user group, and adjust the RRM strategy proportion of the slice user group corresponding to the type of GBR users according to bandwidth parameters of the type of GBR users and user connection parameters of non-GBR users in the cell when the type of GBR users enter the cell. In the scheme, the GBR users are classified to a special slice configured with corresponding resource reservation proportion by a resource reservation hard slice technology in the network slice, and the radio resources of Non-GBR users are prevented from being excessively preempted by the GBR users by dynamically limiting the resource proportion which can be used by all GBR users in a cell, so that the use experience of the network users is improved, and the resource fairness among various users is balanced.

In an implementation manner, as shown in fig. 3 in conjunction with fig. 1, after S102, the resource adjustment method for QoS-based GBR service provided in the embodiment of the present application further includes S103:

s103, when the RRM strategy proportion of the slice user group corresponding to the target GBR user is adjusted to be the target proportion and the target proportion is larger than the maximum threshold value, the base station keeps the RRM strategy proportion of the slice user group corresponding to the target GBR user to be the maximum threshold value.

In the embodiment of the application, when the target CELL (CELL) _5G ) The number of various users in the system is changed, the value of the RRM strategy proportion (such as the maximum proportion of the RRM strategy) is adjusted, and when the maximum proportion of the RRM strategy=X2 and X2 is larger than max (namely the maximum threshold value), the maximum proportion of the RRM strategy=max is kept so as to ensure the use resources of the slice user group corresponding to the target GBR users.

In an implementation manner, the resource adjustment method for the GBR service based on QoS provided in the embodiment of the present application further includes the following S104:

and S104, after the number of GBR users in the target cell is zero and the preset duration is maintained, the base station adjusts the RRM strategy proportion of the slice user group corresponding to the target GBR users to be the maximum threshold value until the GBR users enter the target cell.

In the embodiment of the application, when the target CELL (CELL) _5G ) After the number of GBR users is zero and the duration time Tl, the base station can adjust the RRM policy proportion (such as the maximum proportion of RRM policies) of the slice user group corresponding to the target GBR users to be max (namely the maximum threshold value), and keep max until a new GBR user enters CELL _5G In step S102, the above is repeated.

Illustratively, the present solution adjusts the network resources occupied by GBR users, agrees that the slice IDs of all GBR users with 5 qi=4 in the network are 1-49XXXX, other users than 5 qi=4 cannot use the slice group at the beginning of 1-59XXXX, in this example, the GBR user slice IDs of 5 qi=4 are 1-490001, 1-490002, 1-490003. GBR users of 5 qi=3 are classified as beginning of slice user group 1-59XXXX, the rest and so on. Wherein, the maximum proportion of RRM strategies for the sliced user group of 5 qi=4 (may be referred to as the maximum proportion of RRM strategies 5QI 4) =10%, and the maximum proportion of RRM strategies for the sliced user group of 5 qi=3 (may be referred to as the maximum proportion of RRM strategies 5QI 3) =15%.

When GBR user a (5qi=4, gfbr=10, mfbr=20) enters CELL1, there is no GBR user in CELL1 before, user a is the first GBR user in the CELL, the CELL starts to provide GBR service guarantee for GBR user a, after a duration t1=5 s, the 5G base station calculates a maximum ratio=gfbr according to the formula RRM policy _{A. Total (S)} * Weighting of _A.G +MFBR _{A. Total (S)} * Weighting of _A.M +GFBR _{B. Total (S)} * Weighting of _B.G +MFBR _{B. Total (S)} * Weighting of _B.M Weight of +N _Non-GBR +m, the RRM policy maximum ratio for the 5 qi=4 slice user group of CELL1 is adjusted to be RRM policy maximum ratio 5QI 4=8%.

Over a period of time, due to the rapid change of Non-GBR users in CELL1, the RRM policy maximum ratio of the 5 qi=4 slice user group is secondarily adjusted to RRM policy maximum ratio 5QI 4=9%; at some point, GBR user B with 5 qi=3 (gfbr=15, mfbr=25) goes into CELL1, according to the formula RRM policy maximum ratio=gfbr _{A. Total (S)} * Weighting of _A.G +MFBR _{A. Total (S)} * Weighting of _A.M +GFBR _{B. Total (S)} * Weighting of _B.G +MFBR _{B. Total (S)} * Weighting of _B.M Weight of +N _Non-GBR The +m,5G base station adjusts the RRM policy maximum ratio of the 5 qi=4 sliced user group of CELL1 to RRM policy maximum ratio 5QI 4=7%, and the RRM policy maximum ratio of the 5 qi=3 sliced user group to RRM policy maximum ratio 5QI 3=10%.

When all GBR users leave CELL1 and the duration tl=10s, the 5G base station adjusts the RRM policy maximum proportion of the 5 qi=4 slice user group of CELL1 to RRM policy maximum proportion 5QI 4=10%, and the RRM policy maximum proportion of the 5 qi=3 slice user group to RRM policy maximum proportion 5QI 3=15%.
