Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a network slicing resource management method, apparatus, electronic device, and storage medium. Background Technology

[0002] Network slicing (NS) technology utilizes technologies such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) to virtualize the resources of physical infrastructure into multiple independent and isolated end-to-end logical networks. A single network slice can be used to implement a specific business scenario to meet and adapt to different types of network applications and their quality of service requirements. Because network slicing technology is built on resource virtualization, resource management is the core of managing network slices.

[0003] In related technologies, resource management is based on each network slice group, and each network slice group can contain multiple slices. That is, even if a cell has multiple network slice groups, resource management is performed separately for each network slice group. When using this resource management method, for co-built and shared cells, if both operators want to achieve fairness in resource usage, both operators need to negotiate resources when either operator activates a new network slice group service. This makes the activation of network slice group services very complex and the deployment cycle very long. Summary of the Invention

[0004] This disclosure provides a network slice resource management method, apparatus, electronic device, and storage medium to at least solve the problems of high complexity and long cycle in the resource management methods of related technologies when opening up new network slice groups for services.

[0007] In another possible implementation, the method further includes: creating a target network slice group within the operator's proprietary service group based on the operator's new service information; determining the target reserved resource amount of the target network slice group according to the reserved resource amount of the proprietary service group, wherein the target reserved resource amount is less than the reserved resource amount.

[0008] In another possible implementation, determining the target reserved resource amount for the target network slice group includes: determining the target reserved resource ratio for the target network slice group, wherein the target reserved resource ratio includes at least one of the target dedicated resource ratio, the target minimum resource ratio, and the target maximum resource ratio; wherein the target dedicated resource ratio is less than the dedicated resource ratio, the target minimum resource ratio is less than the minimum resource ratio, and the target maximum resource ratio is less than the maximum resource ratio.

[0009] In another possible implementation, the method further includes: determining resource admission parameters for the target network slice group; the resource admission parameters include at least one of the target number of users, the target number of data radio bearers, and the target physical resource blocks.

[0010] In another possible implementation, the method further includes: determining the shared resource service group within the cell based on the service type of the service corresponding to each network slice within the cell, wherein the shared resource service group includes the public network services of each operator.

[0011] According to a second aspect of this disclosure, a network slice resource management apparatus is provided, comprising: a configuration module configured to perform the following: determining a dedicated service group for each operator based on the PLMN identifier of each network slice in a cell and the service type of the service corresponding to each network slice; the dedicated service group includes at least one network slice group, and the network slice group includes at least one network slice corresponding to the PLMN identifier of the operator; and a determination module configured to perform the following: determining a reserved resource amount for the dedicated service group based on the total resource amount of the cell; the reserved resource amount is less than the total resource amount of the cell.

[0012] In one possible implementation, the determining module is specifically configured to perform: determining the reserved resource ratio for a proprietary business group, wherein the reserved resource ratio includes at least one of a dedicated resource ratio, a minimum resource ratio, and a maximum resource ratio.

[0013] In another possible implementation, the apparatus further includes a creation module configured to perform: creating a target network slice group within the operator's proprietary service group based on the operator's new service information; and determining a target reserved resource amount for the target network slice group based on the reserved resource amount of the proprietary service group, wherein the target reserved resource amount is less than the reserved resource amount.

[0014] In another possible implementation, the creation module is specifically configured to perform: determining the target reserved resource ratio of the target network slice group, wherein the target reserved resource ratio includes at least one of the target dedicated resource ratio, the target minimum resource ratio, and the target maximum resource ratio; wherein the target dedicated resource ratio is less than the dedicated resource ratio, the target minimum resource ratio is less than the minimum resource ratio, and the target maximum resource ratio is less than the maximum resource ratio.

[0015] In another possible implementation, the determining module is further configured to perform: determining resource admission parameters for the target network slice group; the resource admission parameters include at least one of the target number of users, the target number of data radio bearers, and the target physical resource blocks.

[0019] The technical solution provided in this disclosure offers at least the following benefits: It determines the operator to which each network slice belongs based on its PLMN identifier, and determines the network slice group assigned to each dedicated service group based on the service type corresponding to each network slice. By configuring reserved resources for each dedicated service group, the operator achieves unified management of the network slice groups within the dedicated service group, thereby expanding the operator's authority to manage network slice resources. Since the reserved resources configured for the dedicated service group are pre-allocated to the dedicated service group after resource negotiation among various operators within the community, within the scope of the reserved resources, the operator can manage the creation or deletion of network slice groups within the dedicated service group without needing to negotiate resources with other operators. This does not affect the fairness of operator resource usage, enabling operators to manage network slice groups freely and flexibly. It greatly increases the convenience for operators to launch slice group services, significantly shortens the service launch cycle, and reduces service development costs.

[0027] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] Before providing a detailed introduction to the network slice resource management method provided in this disclosure, let's briefly introduce the application scenarios, implementation environment, and related elements involved in this disclosure.

[0030] First, a brief introduction to the application scenarios involved in this disclosure is provided. Network slicing (NS) technology utilizes technologies such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) to virtualize the resources of physical infrastructure into multiple independent and isolated end-to-end logical networks. A single network slice can be used to implement a specific business scenario to meet and adapt to different types of network applications and their quality of service requirements. Since network slicing technology is built on top of resource virtualization, resource management is the core of managing network slices.

[0031] In existing technologies, resource management is based on each network slice group, and each network slice group can contain multiple slices. That is, even if a cell has multiple network slice groups, resource management is performed separately for each network slice group. When using this resource management method, for co-built and shared cells, if both operators want to achieve fairness in resource usage, both operators need to negotiate resources when either operator activates a new network slice group service. This makes the activation of network slice group services very complex and the deployment cycle very long.

[0032] For example, the primary and secondary operators share 2C network user resources, but some 2B services or some 2C OTT-oriented services require additional resource guarantees. Therefore, in addition to the 2C network services, the primary operator also needs a primary 2C slice group and a primary 2B slice group. Similarly, the secondary operator needs a secondary 2C slice group and a secondary 2B slice group. If existing resource management methods are used, when the primary operator wants to open a new 2C slice group, it needs to negotiate with the secondary operator. Only with the secondary operator's consent can the primary operator promote such services nationwide. This results in highly complex service activation and a very long launch cycle.

[0033] However, if the first operator does not negotiate resources with the second operator when launching a new network slice group service, the fairness of resource use between the first and second operators cannot be guaranteed. Furthermore, the new network slice group service can only be launched in the area contracted by the first operator, and the shared area of ​​the first and second operators may not be able to launch the service.

[0034] To address the aforementioned issues, this disclosure provides a network slice resource management method. It determines the operator to which each network slice belongs based on its PLMN identifier and assigns network slice groups to each dedicated service group based on the service type of the corresponding service. By configuring reserved resources for each dedicated service group, the operator achieves unified management of network slice groups within the dedicated service group, thereby expanding the operator's authority to manage network slice resources. Since the reserved resources configured for the dedicated service group are pre-allocated to the dedicated service group after resource negotiation among various operators within the community, within the scope of the reserved resources, the operator can manage the creation or deletion of network slice groups within the dedicated service group without needing to negotiate resources with other operators. This does not affect the fairness of operator resource usage, enabling operators to manage network slice groups freely and flexibly. This greatly increases the convenience for operators to launch slice group services, significantly shortens the service launch cycle, and reduces service development costs.

[0035] Secondly, the implementation environment (implementation architecture) involved in this disclosure will be briefly introduced below.

[0036] The network slicing resource management method provided in this disclosure can be applied to electronic devices. The electronic device can be a base station, a terminal device, or a server. The terminal device can be a smartphone, tablet computer, PDA, vehicle terminal, desktop computer, or laptop computer, etc. The server can be any single server or server cluster; this disclosure does not limit its scope.

[0037] Furthermore, to facilitate understanding of this application, the relevant elements involved in this application are now described.

[0038] A Public Land Mobile Network (PLMN) is a network established and operated by a government or its approved operators for the purpose of providing land mobile communication services to the public. This network is typically interconnected with the Public Switched Telephone Network (PSTN) to form a regional or national-scale communication network.

[0039] The 3GPP protocol specifies the resource allocation and access methods for network slice groups, and stipulates that a network slice group can contain multiple network slices.

[0040] In the resource allocation method for network slice groups, the maximum resource ratio defines the maximum resource usage quota for the network slice group, the minimum resource ratio defines the minimum resource usage quota, and the dedicated resource ratio defines the dedicated resource usage quota. Shared resources represent resources shared between network slices within and outside the network slice group; the shared resource quota is represented by (maximum resource ratio - minimum resource ratio). Priority resources represent resources that network slices within the network slice group have priority in using. When network slices within the group need to use these resources, they must be able to do so. When network slices within the group do not use these resources, they can be used by network slices outside the group. The priority resource quota is represented by (minimum resource ratio - dedicated resource ratio). Dedicated resources represent resources dedicated to network slices within the network slice group; that is, even if network slices within the group do not use these resources, network slices outside the group cannot share them. The dedicated resource quota is represented by the dedicated resource ratio.

[0041] Resource admission methods for network slice groups include: admission control based on the number of users, the number of Data Radio Bearers (DRBs), and Physical Resource Blocks (PRBs). Specifically, user-based admission control allocates different user resources to different network slice groups. If the number of users in the network slice group to which the network slice to be established belongs does not reach the allocated user resource threshold, the user is allowed to establish the network slice. DRB-based admission control allocates different DRB resources to different network slices. If the DRB number in the network slice group to which the network slice to be established belongs does not reach the allocated DRB resource threshold, the user is allowed to establish the network slice. PRB-based admission control allocates different PRB resources to different network slices. If the required PRB resources in the network slice group to which the network slice to be established belongs do not reach the allocated PRB resource threshold, the user is allowed to establish the network slice.

[0042] For ease of understanding, the task processing method provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1 This is a flowchart illustrating a network slice resource management method according to an exemplary embodiment, the method being used in an electronic device. Figure 1 As shown, the network slice resource management method includes the following steps.

[0044] In S101, based on the PLMN identifier of each network slice in the cell and the service type of the service corresponding to each network slice, the proprietary service group of each operator is determined. The proprietary service group includes at least one network slice group, and the network slice group includes at least one network slice corresponding to the operator's PLMN identifier.

[0045] Optionally, the electronic device acquires each network slice of the cell and determines the PLMN identifier of each network slice. Further, based on the PLMN identifier of each network slice and the service type of the service corresponding to each network slice, the proprietary service group of each operator is determined.

[0046] In one implementation, the electronic device acquires each network slice of the cell and determines the PLMN identifier of each network slice, thereby determining the operator to which each network slice belongs. Further, based on the service type of the service corresponding to each network slice, it determines whether the network slice is assigned to an operator's proprietary service group (PSG), thus enabling the determination of each operator's PSG based on the PLMN identifier of each network slice and the service type of the service corresponding to each network slice.

[0047] In one implementation, after assigning multiple network slices to the operator's proprietary service groups, the multiple network slices are grouped according to the service information of the service corresponding to each network slice to construct a network slice group.

[0048] Optionally, the service types corresponding to network slices in a dedicated service group can be divided into public network services and private network services. Among them, private network services include at least one of the operator's 2B services and OTT-oriented 2C services.

[0049] In one implementation, the proprietary services group includes the operator's private network services.

[0050] It is understandable that different operators have different PLMN identifiers.

[0051] It should be noted that each operator's proprietary services group only includes the services of that operator. For example, the proprietary services group of the first operator only includes the services of the first operator and does not include the services of other operators.

[0052] In S102, the reserved resource amount for the dedicated service group is determined based on the total resource amount of the community. The reserved resource amount is less than the total resource amount of the community.

[0053] Optionally, the electronic device allocates reserved resources for each operator's proprietary business group based on the total resources of the cell, wherein the reserved resources for each operator's proprietary business group are less than the total resources of the cell.

[0054] In one implementation, the cell's bandwidth is 100 Mbps, or 273 PRBs. Based on the PLMN identifier of each network slice within the cell and the service type corresponding to each network slice, two operator-specific service groups are divided from the cell's services; for example, this could be a first dedicated service group and a second dedicated service group. When reserving resources for each dedicated service group, a portion of the cell's total resources (i.e., 273 PRBs) can be allocated to the first dedicated service group and the second dedicated service group, respectively.

[0055] Optionally, the reserved resources for each proprietary business group can be freely allocated and used by that proprietary business group.

[0056] In one implementation, after determining the reserved resource amount for a dedicated service group, the available resource amount for each network slice group within the dedicated service group can be determined based on the reserved resource amount. It is understood that if the operator does not create new network slice groups, the sum of the available resource amounts for all network slice groups may be less than or equal to the reserved resource amount. If the operator plans to create new network slice groups, the sum of the available resource amounts for all network slice groups may be less than the reserved resource amount.

[0057] In the above embodiments, the operator to which each network slice belongs is determined based on the PLMN identifier of each network slice, and the network slice group assigned to each dedicated service group is determined based on the service type of the service corresponding to each network slice. By configuring reserved resources for each dedicated service group, the operator achieves unified management of the network slice groups within the dedicated service group, thereby expanding the operator's authority to manage network slice resources. Since the reserved resources configured for the dedicated service group are pre-allocated to the dedicated service group after resource negotiation among various operators within the cell, within the scope of the reserved resources, the operator can manage the creation or deletion of network slice groups within the dedicated service group without needing to negotiate resources with other operators. This does not affect the fairness of operator resource usage, enabling operators to manage network slice groups freely and flexibly. This greatly increases the convenience for operators to launch slice group services, significantly shortens the service launch cycle, and reduces service development costs.

[0058] In one possible implementation, the reserved resource amount for a dedicated service group is determined based on the total resource amount of the cell, including: determining the reserved resource ratio for the dedicated service group, wherein the reserved resource ratio includes at least one of a dedicated resource ratio, a minimum resource ratio, and a maximum resource ratio.

[0059] By configuring at least one of the dedicated resource ratio, minimum resource ratio, and maximum resource ratio for the operator's proprietary service group, the operator can flexibly configure network slice groups and the resource usage of network slice groups within the operator's proprietary service group.

[0060] Optionally, the total resource volume of network slice groups within a dedicated service group (VSS) is limited by the reserved resource volume of the VSS. Specifically, the sum of the dedicated resource ratios of all slice groups within a VSS is less than or equal to the total dedicated resource ratio of the VSS; the sum of the minimum resource ratios of all slice groups within a VSS is less than or equal to the total minimum resource ratio of the VSS; and the sum of the maximum resource ratios of all slice groups within a VSS is less than or equal to the total maximum resource ratio of the VSS. Furthermore, the sum of the dedicated resource ratios of all operators' VSS groups is less than or equal to the sum of the minimum resource ratios of all operators; and the sum of the minimum resource ratios of all operators is less than or equal to the sum of the maximum resource ratios of all operators, where the sum of the maximum resource ratios of all operators is 100%.

[0061] In one implementation, the cell is configured with 100M bandwidth, or 273 PRBs. If neither of the two operators in the current cell has a dedicated service group, that is, the dedicated resource ratio of the dedicated service groups of the first operator 1 and the second operator is 0%, the minimum resource ratio is 0%, and the maximum resource ratio is 0%.

[0062] In another implementation, the cell is configured with 100M bandwidth, or 273 PRBs. If both operators in the current cell have dedicated service groups (VSSs), according to the negotiation between the two operators, the dedicated resource ratio of the first operator's VSS is 10%, with a minimum resource ratio of 20% and a maximum resource ratio of 40%. The dedicated resource ratio of the second operator's VSS is also 10%, with a minimum resource ratio of 20% and a maximum resource ratio of 40%. Based on this, each operator can freely create new slice group services within the resource ratio range of the VSS without having to negotiate with other operators, greatly reducing the complexity of operators launching slice group services and shortening the launch cycle of slice group services.

[0063] In another implementation, the cell is configured with 100M bandwidth, or 273 PRBs. If both operators in the current cell have dedicated service groups (VSSs), according to the negotiation between the two operators, the dedicated resource ratio of the first operator's VSS is 0%, the minimum resource ratio is 20%, and the maximum resource ratio is 40%. The dedicated resource ratio of the second operator's VSS is 0%, the minimum resource ratio is 20%, and the maximum resource ratio is 40%. Based on this, each operator can freely create new slice group services within the resource ratio range of the VSS without having to negotiate with other operators, greatly reducing the complexity of operators launching slice group services and shortening the launch cycle of slice group services.

[0064] Optionally, the dedicated resource ratio is used to characterize the dedicated resource usage quota of the dedicated business group, the minimum resource ratio is used to characterize the minimum resource usage quota of the dedicated business group, and the maximum resource ratio is used to characterize the maximum resource usage quota of the dedicated business group.

[0065] In the above embodiments, by configuring at least one of the dedicated resource ratio, minimum resource ratio, and maximum resource ratio for each operator's proprietary business group, network resources that can be freely used by each operator are allocated, so that operators can freely develop their businesses within the allocated network resource range. While ensuring equivalence of operator resources, this greatly reduces the complexity of operators launching services and shortens the service launch cycle.

[0066] Another possible implementation, combined with Figure 1 ,like Figure 2 As shown, the network slice resource management method also includes S103-S104. It is understood that S103-S104 are executed by electronic devices.

[0067] In S103, a target network slice group is created within the operator's proprietary service group based on the operator's new service information.

[0068] In one implementation, the electronic device creates a target network slice group within the operator's proprietary service group based on the operator's new service information.

[0069] For example, if a first operator wants to develop 2B network slice group services and 2C network slice group services, it can create its own 2B network slice group services and 2C network slice group services within its own dedicated service group, and then configure the target reserved resource amount according to the needs of each network slice group.

[0070] In S104, the target reserved resource amount for the target network slice group is determined based on the reserved resource amount of the dedicated service group. The target reserved resource amount is less than the reserved resource amount.

[0071] In one implementation, after creating a target network slice group, the electronic device configures a target reserved resource amount for the target network slice group based on the reserved resource amount of the dedicated service group. The target reserved resource amount is less than the reserved resource amount. Furthermore, the sum of the target reserved resource amount and the available resource amount of the original network slice group within the dedicated service group should be less than or equal to the reserved resource amount of the dedicated service group.

[0072] For example, an electronic device may allocate a portion of the reserved resources of a proprietary service group to a target network slice group.

[0073] Optionally, the target reserved resource amount is used to characterize the available resource amount of the target network slice group.

[0074] In the above embodiments, a target network slice group is created within the operator's proprietary business group using the operator's new service information. This target network slice group is used to launch new services, and a target reserved resource amount is configured for the new services. Since the newly created target network slice group belongs to the operator's proprietary business group and occupies the reserved resource amount of the proprietary business group, rather than shared resources between operators, creating the target network slice group without consulting with other operators does not affect the principle of fairness in resource use among operators. This greatly increases the convenience for operators to launch new services and significantly shortens the launch cycle of new services.

[0075] In one possible implementation, determining the target reserved resource amount for the target network slice group includes: determining the target reserved resource ratio for the target network slice group, wherein the target reserved resource ratio includes at least one of a target dedicated resource ratio, a target minimum resource ratio, and a target maximum resource ratio. Specifically, the target dedicated resource ratio is less than the dedicated resource ratio, the target minimum resource ratio is less than the minimum resource ratio, and the target maximum resource ratio is less than the maximum resource ratio.

[0076] In one implementation, the cell is configured with 100M bandwidth, or 273 PRBs. If both operators in the current cell have set up dedicated service groups, according to the negotiation between the two operators, the dedicated resource ratio of the first operator's dedicated service group is 10%, with a minimum resource ratio of 20% and a maximum resource ratio of 40%. The dedicated resource ratio of the second operator's dedicated service group is 10%, with a minimum resource ratio of 20% and a maximum resource ratio of 40%. Based on this, each operator can freely create new slice group services within the resource ratio range of the dedicated service group without having to negotiate with other operators, greatly reducing the complexity of operators launching slice group services and shortening the launch cycle of slice group services.

[0077] For example, if a first operator wants to develop 2B and 2C network slice group services, it can create its own 2B and 2C network slice groups within its dedicated service group. Then, it can configure the dedicated resource ratio, minimum resource ratio, and maximum resource ratio of the network slice groups according to its needs. For instance, the dedicated resource ratio for the first operator's 2B network slice group might be 3%, the minimum resource ratio might be 8%, and the maximum resource ratio might be 30%. Similarly, the dedicated resource ratio for the first operator's 2C network slice group might be 5%, the minimum resource ratio might be 10%, and the maximum resource ratio might be 30%. Since the newly created network slice groups use the pre-configured reserved resources for its own dedicated service group and do not use network resources shared with the second operator, the first operator does not need to negotiate with the second operator when developing services within its dedicated service group.

[0078] In another implementation, the cell is configured with 100M bandwidth, or 273 PRBs. If both operators in the current cell have dedicated service groups (VSSs), according to the negotiation between the two operators, the dedicated resource ratio of the first operator's VSS is 0%, the minimum resource ratio is 20%, and the maximum resource ratio is 40%. The dedicated resource ratio of the second operator's VSS is 0%, the minimum resource ratio is 20%, and the maximum resource ratio is 40%. Based on this, each operator can freely create new slice group services within the resource ratio range of the VSS without having to negotiate with other operators, greatly reducing the complexity of operators launching slice group services and shortening the launch cycle of slice group services.

[0079] For example, if a first operator wants to develop 2B and 2C network slice group services, it can create its own 2B and 2C network slice groups within its proprietary service group. Then, it can configure the dedicated, minimum, and maximum resource ratios for these slice groups according to its needs. For instance, the dedicated resource ratio for the first operator's 2B network slice group might be 0%, the minimum resource ratio 10%, and the maximum resource ratio 30%. Similarly, the dedicated resource ratio for the first operator's 2C network slice group might be 0%, the minimum resource ratio 10%, and the maximum resource ratio 30%. Since the newly created network slice groups use the pre-configured reserved resources for the first operator's proprietary service group and do not use network resources shared with the second operator, the first operator does not need to negotiate with the second operator when developing services within its proprietary service group.

[0080] In the above embodiments, by configuring at least one of the target dedicated resource ratio, target minimum resource ratio, and target maximum resource ratio for the target network slice group, usable resources are allocated to each target network slice group, thereby ensuring that the target network slices within the target network slice group have usable resources and guaranteeing the smooth launch of new services by the operator.

[0081] In one possible implementation, the network slice resource management method further includes: determining resource admission parameters for a target network slice group. The resource admission parameters include at least one of the following: target number of users, target number of data radio bearers, and target physical resource blocks.

[0082] Optionally, the target number of users is used to characterize the number of users that can be allocated to the target network slice group. The target number of data radio bearers is used to characterize the number of DRBs that can be allocated to the target network slice group. The target number of physical resource blocks is used to characterize the number of PRBs that can be allocated to the target network slice group.

[0083] For example, if it is necessary to create a new target network slice within a target network slice group, and the current number of users, the current number of DRBs, and the current number of PRBs in the target network slice group to which the target network slice to be created belongs have not reached the target number of users, the current number of DRBs have not reached the target number of DRBs, and the current number of PRBs have not reached the target number of PRBs, then it is allowed to create a new target network slice within the target network slice group.

[0084] In the above embodiments, by configuring resource admission parameters for the target network slice group, resource thresholds for the target network slice group can be set to determine whether new slices are allowed to be created within the target network slice group.

[0085] In one possible implementation, combining Figure 1 ,like Figure 3 As shown, the network slice resource management method also includes: S105. S105 is used in electronic devices.

[0086] In S105, based on the service type of each network slice in the cell, the shared resource service group in the cell is determined. The shared resource service group includes the public network services of each operator.

[0087] Optionally, the electronic device determines the network slice corresponding to the public network service based on the service type of each network slice. Further, the network slice corresponding to the public network service is assigned to a shared resource service group.

[0088] In one implementation, services within a shared resource service group are conducted in a fully shared manner, meaning that each operator's services can utilize the resources configured within the shared resource service group.
