Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and particularly relates to a resource adjustment method and device for GBR service based on QoS and a storage medium. BACKGROUND

[0002] In a network, Quality of Service (QoS) flows can be divided into Guaranteed Bit Rate (GBR) QoS flows and Non-GBR QoS flows. Among them, the service using the GBR QoS flow to transmit data is a bandwidth guarantee service, and the service using the Non-GBR QoS flow to transmit data is a non-bandwidth guarantee service. In the network, whether it is a GBR QoS flow or a Non-GBR QoS flow, corresponding resources need to be configured, such as radio resources.

[0003] However, when multiple GBR users and Non-GBR users exist in the same cell at the same time, in order to guarantee the bandwidth guarantee service of the GBR user, the base station will reserve resources for the GBR user, and allow the GBR user to preempt the resources of the Non-GBR user, thereby causing the scarcity of Non-GBR user resources, which is not conducive to the overall operation of the operator. SUMMARY

[0036] Hereinafter, the terms / names related to the embodiments of the present application are explained to facilitate the understanding of the readers.

[0037] 1、5G network slice divides the physical network into multiple logical virtual networks, and assigns different SLA (Service-Level Agreement) to the logical networks, so as to realize the function of network slice providing customized network service for customers.

[0038] Network slicing technology divides the physical network into multiple virtual private networks, each of which can provide different network capabilities, so as to meet the differentiated network requirements, and also simplify the management of industrial user groups.

[0039] In network slicing, end-to-end service control is realized through slice identification (Single Network Slice Selection Assistance Information, S-NSSAI), which is composed of Slice Service Type (SST) and slice Differentiator (SD) and exists uniquely in the terminal, wireless network and core network. Among them, the length of SST is 8 bits, which is used to indicate the slice type, of which 0-127 is defined by the standard and 128-255 is defined by the operator.

[0040] Currently, 3GPP defines five standard SST values of eMBB, uRLLC, MIoT, V2X and HMTC, as shown in the following Table 1. The length of SD is 24 bits, which differentiates the slice instances in the same SST, such as tenant information, etc. The SD value is defined by the operator, and the operator can formulate the SD value according to the specific needs of 5G SA public network and 5G SA industry network for slice / service.

[0043] Network slicing technology is an end-to-end technology that runs through the wireless, transmission and core three sub-domains in the network. In the wireless end, the commonly used slicing technologies include Resource Block (RB) resource reservation and QoS priority scheduling two technologies, in which:

[0044] RB resource reservation slice technology realizes wireless resource guarantee and isolation through radio resource management (RRM) strategy and protection mechanism. There are three types of resources that can be used for slice user guarantee reservation in the standard, which are physical resource block (PRB) resources, data radio bearer (DRB) usage rate and radio resource control (RRC) connection user number. Slice users are defined by public land mobile network (PLMN) identifier and S-NSSAI, and multiple S-NSSAIs form a slice group.

[0045] Currently, domestic operators usually use radio resource management (RRM) strategy for wireless resource isolation guarantee of PRB resources.

[0046] In the standard protocol, the same carrier width can be divided into different numbers of RBs when using different subcarrier spacings. By reserving a certain proportion of PRB resources for customers, PRB resource isolation guarantee can be provided for customers. The RB division of FR1 frequency band is shown in Table 2, wherein the maximum transmission bandwidth configuration of FR1 is N RB :

[0047] Table 2

[0048]

[0049]

[0050] 2、QoS is a security mechanism of communication network, which can be used to solve network delay and congestion problems. Communication network can guarantee the communication quality of users through QoS technology. For example, core network equipment can formulate QoS parameters and QoS strategy according to the subscription information of customers or preset strategy, and network equipment can realize and guarantee QoS strategy according to QoS parameters.

[0051] The QoS flow can be divided into GBR QoS flow and Non-GBR QoS flow according to QoS profile. The QoS parameters of QoS profile can include one or more of the following parameters: 5G QoS identity document (5QI), Allocation and Retention Priority (ARP). Among them, the GBR QoS flow can include one or more of the following: guaranteed flow bit rate (GFBR), maximum flow bit rate (MFBR), notification control, maximum packet loss rate (only applicable to voice service). The MFBR (Maximum Flow Bit Rate) is the upper limit of the rate of GBR service, which is a non-guaranteed rate; GFBR is the guaranteed bandwidth of GBR service, which is the bandwidth permanently allocated by the network for the subscriber, and GFBR≤MFBR.

[0052] The Non-GBR QoS flow can contain Session-AMBR (per Session Aggregate Maximum Bit Rate), UE-AMBR (per UE Aggregate Maximum Bit Rate) reflective QoS attribute (RQA). Among them, Session-AMBR limits the maximum bandwidth shared by all non-GBR QoS flows of a PDU session, and UE-AMBR limits the maximum bandwidth shared by all non-GBR QoS flows of a user.

[0053] If the service type of the terminal device is a service that requires GBR rate guarantee, the network device can establish a GBR QoS flow for the terminal device, and the GBR rate of the GBR QoS flow is the GFBR corresponding to the service, and the maximum rate is the MFBR.

[0054] The packets in the QoS flow within the GFBR commitment rate are all forwarded. The part of data exceeding the GFBR and below the MFBR and the Non-GBR QoS flow are scheduled according to the weight, and the weight of this part in the existing network is generally higher than that of the non-GBR QoS flow.

[0055] When the GFBR guarantee bandwidth in the GBR QoS flow cannot be obtained, the wireless base station can select to send a notification to the session management function (SMF) through Notification Control, while continuing to maintain the normal operation of the QoS flow.

[0056] 3. Shared resources: means the resources shared with other slice user groups (i.e. the slice user groups defined in the RRM Policy Ratio name). Shared resources are not guaranteed to be used by the associated slice users. The shared resource quota is represented by [RRM Policy Max Ratio-RRM Policy Min Ratio], that is, means.

[0057] Prioritized resources: means that the resources are used by the associated slice user group in priority. These resources are guaranteed to be used by the associated slice user group when needed. When not used, these resources can be used by other slice user groups (i.e. the slice user groups defined in the RRM Policy Ratio name). The quota of prioritized resources is represented by [RRM Policy Min Ratio-RRM Policy Dedicated Ratio].

[0058] Dedicated resources: means that the resources are dedicated for use by the associated slice user group. Even if the associated slice user does not use these resources, these resources cannot be shared. The dedicated resource quota is represented by [RRM Policy Dedicated Ratio].

[0059] The basic granularity of a network slice is a protocol data unit (PDU) session. One network slice of a terminal device can contain one or more PDU sessions. A PDU session can contain multiple QoS flows. The terminal device and the network device can perform data transmission on the QoS flow.

[0060] In the following, the resource adjustment method for GBR service based on QoS provided by the embodiments of the present application is described through specific scenarios and implementation manners.

[0061] Currently, in the network, resources need to be reserved for GBR QoS flow, and Non-GBR QoS flow service does not need to be reserved; at the same time, the resources of GBR QoS flow cannot be preempted, while the resources of Non-GBR QoS flow can be preempted by GBR QoS flow. This brings a problem, because most of the public network ordinary users' services in the existing network are transmitted through Non-GBR QoS flow, and when the special VIP user excessively uses GBR QoS flow to transmit service data, it is possible to excessively preempt the Non-GBR QoS flow service resources of ordinary users, thereby causing the use experience of ordinary users to decline, which is not conducive to the overall operation of the operator. In the 5G era, how to limit the excessive occupation of transmission resources by GBR QoS flow in network slicing, prevent special VIP users from excessively preempting ordinary user resources, and balance the resources of VIP customers and ordinary users is a problem that needs to be solved.

[0062] It should be noted that the user using GBR QoS flow to transmit data is usually a high-priority VIP user (which can be referred to as a GBR user), and the user using Non-GBR QoS flow to transmit data is usually a relatively low-priority ordinary user (which can be referred to as a Non-GBR user).

[0063] In order to solve the problem of how to limit the excessive occupation of transmission resources by GBR QoS flow in the network, prevent special VIP users from excessively preempting ordinary user resources, and balance the resources of VIP customers and ordinary users in the prior art, the present application provides a resource adjustment method for GBR service based on QoS. The base station can configure at least one slice user group for at least one type of GBR user in a cell, configure an RRM policy ratio for each slice user group, and when a certain type of GBR user enters the cell, adjust the RRM policy ratio of the slice user group corresponding to the certain type of GBR user according to the bandwidth parameters of each type of GBR user in the cell and the user connection parameters of Non-GBR users. In the present scheme, through the resource reservation hard slicing technology in network slicing, the GBR users are classified into a special slice configured with a corresponding resource reservation ratio, and by dynamically limiting the resource ratio that can be used by all GBR users in the cell, the excessive preemption of wireless resources of Non-GBR users by GBR users is avoided, the use experience of network users is improved, and the resource fairness among various users is balanced.

[0064] It should be noted that the maximum RRM policy ratio in this paper refers to the RRM Policy Max Ratio, which defines the maximum resource usage quota for a slice user group. The minimum RRM policy ratio in this paper refers to the RRM Policy Min Ratio, which defines the minimum resource usage quota for a slice user group. The dedicated RRM policy ratio in this paper refers to the RRM Policy Dedicated Ratio, which defines the dedicated resource usage quota for a slice user group. For detailed explanations, please refer to the descriptions in the following embodiments, which will not be repeated here.

[0065] like Figure 1 The diagram shows a flowchart of a resource adjustment method for GBR services based on QoS provided in this application embodiment. The method includes the following steps S101 and S102:

[0066] S101. The base station configures at least one slice user group for at least one type of GBR user in the target cell, and configures the RRM policy ratio for each slice user group.

[0067] In this embodiment of the application, the above-mentioned RRM policy ratio is used to characterize the resource usage quota of the slice user group.

[0068] It should be noted that GBR users refer to 5G users who conduct services through GBR QoS streams in the 5G network.

[0069] In one implementation, the aforementioned RRM strategy ratio includes at least one of the following: maximum RRM strategy ratio, minimum RRM strategy ratio, and dedicated RRM strategy ratio.

[0070] Among them, the maximum RRM policy ratio is used to represent the maximum resource usage quota of the slice user group, the minimum RRM policy ratio is used to represent the minimum resource usage quota of the slice user group, and the dedicated RRM policy ratio is used to represent the dedicated resource usage quota of the slice user group.

[0071] In this embodiment of the application, the 5G base station cell (which can be represented as CELL) 5G Configure multiple slice user groups for GBR users (e.g., slice user group for type A GBR users is S-NSSAI=1-AXXXXX, slice user group for type B GBR users is S-NSSAI=1-BXXXXX), and configure each slice user group as a hard slice reserved for RB resources. RB resource reservation is configured through RRM policy ratios. For example, initially set the maximum RRM policy ratio for type A slice user groups.

[0072] =max.A, the maximum proportion of RRM strategy for user groups in slice B is =max.B, and so on for the rest.

[0073] It should be noted that the RRM policy limits the resource type and quantity used by the RB resource slice user or user group (the slice user is defined by the slice identifier, and the users of different slices can constitute a slice user group) through the RRM policy ratio. Among them:

[0074] The RRM policy maximum ratio attribute defines the maximum resource usage quota of the related 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 of all slice users can be greater than 100.

[0075] The RRM policy minimum ratio attribute defines the minimum resource usage quota of the associated slice user group, including at least one of priority resources and dedicated resources, that is, the resource quota that needs to be guaranteed for the associated slice user group. For example, the sum of the "RRM policy minimum ratio" values should be less than or equal to 100.

[0076] The RRM policy dedicated ratio attribute defines the dedicated resource usage quota of the slice user group, including dedicated resources. For example, the sum of the "RRM policy dedicated ratio" values should be less than or equal to 100.

[0077] S102, in the case that the target class GBR user enters the target cell, the base station adjusts the RRM policy ratio of the slice user group corresponding to the target class GBR user according to the bandwidth parameters of each class GBR user in the target cell and the user connection parameters of the non-GBR user.

[0078] It can be understood that the base station (for example, a 5G base station) can set the RRM policy ratio (for example, the RRM policy maximum ratio, the RRM policy minimum ratio, and the RRM policy dedicated ratio) of the PRB resource reservation of different slice user groups. The base station can dynamically adjust the RRM policy ratio (for example, the RRM policy maximum ratio) of the slice user group according to the bandwidth parameters of all GBR users in the base station cell (which can be represented as CELL 5G ) and the user connection parameters of the non-GBR user. It should be noted that the adjustment range of the RRM policy maximum ratio is 1-max (max is the maximum threshold value evaluated by the system).

[0079] For example, the standard defines multiple classes of 5QI GBR guarantee levels, such as 5QI=3 and 5QI=4. A class GBR user (the number of users can be one or more) enters the target cell (for example, CELL 5G ), and the GFBR (which can be represented as GFBRA ) is configured by the network as GFBR A = G A , and the MFBR of the A-type GBR user (which can be represented as MFBR A ) is 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.

[0080] It should be noted that the Non-GBR user refers to a 5G user in the 5G network that uses a Non-GBR QoS flow for service.

[0081] Multiple resource reservation network slice groups: multiple types of PRB resource reservation network slice user groups are pre-configured in the network, all users using a GBR QoS flow are classified into one slice user group, and the slice ID can be set to have a certain feature, for example, S-NSSAI = 1-AXXXXX is classified into one slice user group.

[0082] In an implementation manner, the bandwidth parameters include GFBR and MFBR.

[0083] In an implementation manner, the user connection parameters include the number of online Non-GBR users, the number of PDU sessions of Non-GBR users, and the maximum bandwidth (Aggregate Maximum Bit Rate, AMBR) of Non-GBR data flow of all UEs under the target cell.

[0084] In the embodiments of the present application, the base station can count the Non-GBR user indicators under the target cell (CELL 5G ), including but not limited to: the number of online Non-GBR users C user (i.e., the number of users in the RRC connected state), the number of PDU sessions of Non-GBR users C PDU , the total bandwidth AMBR 总 = AMBR1 + AMBR2 + AMBR3 +... of UE-AMBR (per UE Aggregate Maximum Bit Rate) of all UEs under the target cell.

[0085] In the embodiment of the present application, the SMF network element receives a session establishment request initiated by a UE, establishes a dedicated QOS flow for the UE, and sends a PDR of the dedicated QOS flow to a user plane function (UPF) network element. The UPF network element receives and performs service detection on the UE according to the PDR, and if the detected service meets the PDR, reports a service event to the SMF network element. The SMF network element performs state switching of GBR or Non GBR of the dedicated QOS flow according to the service event reported by the UPF network element. The present scheme realizes real-time monitoring of service information of the UE by the UPF network element, and notifies the SMF network element of the service usage change of the UE. The SMF network element dynamically adjusts the QOS flow attribute according to the received notification information, and adjusts the QOS flow to be GBR or Non GBR, so as to meet the use of exclusive bandwidth of the customer, and realize full and effective use of the bandwidth resources of the 5G network, thereby avoiding waste of bandwidth resources.

[0086] In one implementation manner, the method is combined with Figure 1 As shown in the S102, the S102 can be implemented by the following S102a and S102b. Figure 2

[0087] In the S102a, in a case that the target GBR user enters the target cell, the base station calculates total GFBR and total MFBR of each type of GBR user in the target cell.

[0088] In the embodiment of the present application, the base station can count the statistical indicators of online GBR users of each type in the target cell (CELL 5G ), including but not limited to: GFBR A total bandwidth GFBR A.总 of the A-type GBR user is GFBR A 1+GFBR A 2+GFBR A 3+...+GFBR A n (n is the number of A-type GBR users), and MFBR A total bandwidth is MFBR A.总 1+MFBR A 2+MFBR A 3+...+MFBR A n; GFBR A total bandwidth GFBR B of the B-type GBR user is GFBR B.总 1+GFBR B 2+GFBR B 3+...+GFBR B m (m is the number of B-type GBR users), and MFBR B total bandwidth is MFBR B 1+MFBR B.总 2+MFBR B ​1+M B 2+M B 3+...+M B m; and so on, until the total GFBR and total MFBR of all GBR users in the target cell are summed up.

[0089] S102b, the base station adjusts the RRM strategy proportion of the slice user group corresponding to the target GBR user according to the total GFBR and total MFBR of each type of GBR user, and the weight of at least one first weight and user connection parameter.

[0090] In the embodiments of the present application, the at least one first weight is a weight set for the total GFBR and total MFBR of each type of GBR user.

[0091] In the embodiments of the present application, the base station can adjust the RB resource reservation proportion of each type of GBR corresponding to the slice user group in the target cell according to the total GFBR and total MFBR of each type of GBR user in the target cell and the user connection parameter of the non-GBR user, and the maximum proportion of the RRM strategy is X, where X = GFBR A.总 *weight A.G +MFBR A.总 *weight A.M +GFBR B.总 *weight B.G +MFBR B.总 *weight B.M +N*weight Non-GBR +M. Wherein the weight Non-GBR is a value in the finite set {A, B, C...}.

[0092] Exemplary:

[0093] When the threshold value 1≤C user *weight user +C PDU *weight PDU +AMBR 总 *weight AMBR ≤threshold value 2, the weight Non-GBR =A;

[0094] When the threshold value 2<C user *weight user +C PDU *weight PDU +AMBR 总 *weight AMBR ≤threshold value 3, the weight Non-GBR =B;

[0095] When the threshold value 3<C user *weight user +C PDU *weightPDU + AMBR 总 * weight AMBR ≤ threshold 4, weight Non-GBR = C.

[0096] It should be noted that the symbol "*" in the embodiments of the present application represents multiplication.

[0097] Here, the weight Non-GBR is set to an interval value, in order to avoid frequent adjustment of the RRM strategy proportion (such as the maximum RRM strategy proportion) caused by rapid changes in the number of ordinary users and the number of PDU sessions under the cell.

[0098] The weight A.G , the weight A.M , the weight B.G , the weight B.M , the weight Non-GBR , and the like, the constant N and the constant M, the threshold 1 to the threshold k (k is the number of GBR users) are flexibly set according to the base station user radio resource scheduling algorithm.

[0099] In the embodiments of the present application, the total amount of resources that can be used by the GBR users in the base station cell is limited by the RB resource reservation hard slice method, so as to avoid excessive occupation of Non-GBR user resources by GBR users. Moreover, when setting the maximum available resources (maximum RRM strategy proportion) of the RB resource reservation hard slice, in addition to considering the guaranteed bandwidth GFBR and the maximum bandwidth MFBR of the GBR users, the user connection parameters related to the Non-GBR users are also considered, such as the RRC online connection number, the PDU session number, and the AMBR of the Non-GBR data flow of the UE. The base station dynamically adjusts the value of the RRM strategy proportion (such as the maximum RRM strategy proportion) through these indicators, which can maximize the guarantee of the GBR user experience while not reducing the use experience of the Non-GBR user, and balance the resource fairness between the GBR service flow users and the Non-GBR service flow users.

[0100] The embodiment of the present 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 user in a cell, configure an RRM strategy ratio for each slice user group, and when a certain type of GBR user enters the cell, adjust the RRM strategy ratio of the slice user group corresponding to the certain type of GBR user according to the bandwidth parameter of each type of GBR user in the cell and the user connection parameter of a non-GBR user. In the scheme, the GBR user is classified into a special slice configured with a corresponding resource reservation ratio through the resource reservation hard slice technology in the network slice, the resource ratio that can be used by all GBR users in the cell is dynamically limited, the wireless resource of the non-GBR user is avoided from being excessively occupied by the GBR user, the use experience of the network user is improved, and the resource fairness among various users is balanced.

[0101] In an implementation manner, the method comprises the following steps of: Figure 1 As shown in the following S102, the embodiment of the present application provides a resource adjustment method of GBR service based on QoS, which comprises the following steps of: Figure 3 As shown in the following S102, the embodiment of the present application provides a resource adjustment method of GBR service based on QoS, which comprises the following steps of:

[0102] S103, when the RRM strategy ratio of the slice user group corresponding to the target type of GBR user is adjusted to the target ratio, and the target ratio is greater than the maximum threshold value, the base station keeps the RRM strategy ratio of the slice user group corresponding to the target type of GBR user as the maximum threshold value.

[0103] In the embodiment of the present application, when the number of each type of user in the target cell (CELL 5G ) changes, and the value of the RRM strategy ratio (for example, the maximum ratio of RRM strategy) is adjusted, the maximum ratio of RRM strategy is X2, and X2 is greater than max (that is, the maximum threshold value), the maximum ratio of RRM strategy is kept as max, so as to guarantee the use of resources of the slice user group corresponding to the target type of GBR user.

[0104] In an implementation manner, the method comprises the following steps of:

[0105] S104, when the number of GBR users in the target cell is zero, and after a preset time length, the base station adjusts the RRM strategy ratio of the slice user group corresponding to the target type of GBR user to the maximum threshold value, until a GBR user enters the target cell.

[0106] In the embodiment of the present application, when the number of each type of user in the target cell (CELL 5G) and lasts for a duration Tl, the base station can adjust the RRM strategy proportion (e.g. RRM strategy maximum proportion) of the slice user group corresponding to the target GBR user to max (i.e. the maximum threshold value), and keep it as max until a new GBR user enters the cell 5G S102 is repeated.

[0107] For example, the scheme adjusts the network resources occupied by GBR users, and stipulates that the slice IDs of all GBR users with 5QI = 4 in the network are 1-49XXXX, and other users with 5QI ≠ 4 cannot use the slice group starting with 1-59XXXX. In this example, the slice IDs of GBR users with 5QI = 4 are 1-490001, 1-490002, 1-490003, and so on. GBR users with 5QI = 3 belong to the slice user group starting with 1-59XXXX, and the rest are similar. The RRM strategy maximum proportion of the slice user group with 5QI = 4 (which can be referred to as RRM strategy maximum proportion 5QI4) is 10%, and the RRM strategy maximum proportion of the slice user group with 5QI = 3 (which can be referred to as RRM strategy maximum proportion 5QI3) is 15%.

[0108] When GBR user A (5QI = 4, GFBR = 10, MFBR = 20) enters cell 1, there is no GBR user in the cell before, and user A is the first GBR user in the cell. The cell starts to provide GBR service guarantee for GBR user A, and after a duration T1 = 5s, the 5G base station adjusts the RRM strategy maximum proportion of the 5QI = 4 slice user group in cell 1 according to the formula RRM strategy maximum proportion = GFBR A.总 * weight A.G + MFBR A.总 * weight A.M + GFBR B.总 * weight B.G + MFBR B.总 * weight B.M + N * weight Non-GBR + M.

[0109] After a period of time, due to the rapid change of Non-GBR users under cell 1, the RRM strategy maximum proportion of the 5QI = 4 slice user group is adjusted to RRM strategy maximum proportion 5QI4 = 9% for the second time; at a certain moment, GBR user B (5QI = 3, GFBR = 15, MFBR = 25) enters cell 1, and according to the formula RRM strategy maximum proportion = GFBR A.总 * weight A.G + MFBR A.总 * weight A.M+GFBR B.总 *Weight B.G +MFBR B.总 *Weight B.M +N*weight Non-GBR +M, the 5G base station will adjust the maximum RRM policy ratio of the 5QI=4 slice user group in CELL1 to the maximum RRM policy ratio of 5QI4=7%, and the maximum RRM policy ratio of the 5QI=3 slice user group to the maximum RRM policy ratio of 5QI3=10%.

[0110] After all GBR users leave CELL1 and the duration is Tl=10s, the 5G base station will adjust the maximum RRM policy ratio of the 5QI=4 slice user group in CELL1 to the maximum RRM policy ratio 5QI4=10%, and the maximum RRM policy ratio of the 5QI=3 slice user group to the maximum RRM policy ratio 5QI3=15%.
