Description

Technical Field

[0001] The invention relates to a network management system and method for automatic adjustment of a virtualized base station. Background Art

[0002] Currently, telecom operators use the traditional method, that is, to use a fixed maximum network resource configuration to meet terminal service needs. However, new-generation mobile network applications (such as extended reality (XR) services) have an increasing demand for resources and consume more and more energy. Under the global trend of energy conservation and carbon reduction, the traditional operation method of consuming the maximum network resources will not be cost-effective. Telecom operators need to adopt energy-saving network resource configuration technology.

[0003] The rise of virtualized base station technology provides dynamic network resource configuration technology, which can help telecom operators effectively reduce the waste of network resources. However, the current technology takes a while to configure the resources of virtualized base stations, which causes a window period, resulting in the inability of the network management system to allocate appropriate resources in real time to meet user service needs in a frequently changing network. Summary of the invention

[0004] The present disclosure provides a network management system and method for automatic adjustment of a virtualized base station, which can avoid the situation where the resource demand of a user equipment (UE) cannot be met during a window period caused by the resource configuration of the virtualized base station.

[0005] The present invention discloses a network management system for automatic adjustment of virtualized base stations, comprising a processor, a storage medium and a transceiver. The storage medium stores multiple modules. The processor is coupled to the storage medium and the transceiver, and accesses and executes multiple modules, wherein the multiple modules include a monitoring entity, a user equipment information processing process, a scaling configuration entity and a virtualized radio access network management entity. The monitoring entity is connected to the core network through the transceiver. The user equipment information processing process queries the core network for a user equipment information table through the monitoring entity, and queries the first reserved resources of the first virtualized base station through the monitoring entity, wherein the user equipment information table includes first location information and a first resource requirement corresponding to a first user equipment set. The scaling configuration entity obtains a second resource requirement corresponding to a second user equipment set from the user equipment information table according to the first location information and a default range, and determines whether the first reserved resources match the second resource requirement to generate a judgment result. The virtualized radio access network management entity expands or reduces the first reserved resources of the first virtualized base station according to the judgment result.

[0006] In one embodiment of the present disclosure, the plurality of modules further include a user equipment resource controller. The user equipment resource controller stores a default range and a mapping table, wherein the scaling configuration entity converts the first reserved resource into a resource value according to the mapping table, and determines whether the resource value matches the second resource requirement to generate a determination result.

[0007] In an embodiment of the present disclosure, the resource value mentioned above includes a first service level agreement value, and the second resource requirement includes a second service level agreement value.

[0008] In one embodiment of the present disclosure, the service range of the first virtualized base station is included in the default range.

[0009] In an embodiment of the present disclosure, the user equipment information processing process queries the unified data management function of the core network for a list of the first user equipment set to obtain a user equipment information table.

[0010] In an embodiment of the present disclosure, the above-mentioned user equipment information processing process queries the first resource requirement from the policy control function of the core network.

[0011] In one embodiment of the present disclosure, the user equipment information processing process queries the gateway mobile location center function or location search function of the core network for the first location information.

[0012] In one embodiment of the present disclosure, the above-mentioned virtualized radio access network management entity expands or reduces the first reserved resources of the first virtualized base station and the second reserved resources of the second virtualized base station according to the judgment result, wherein the first virtualized base station and the second virtualized base station belong to the same centralized unit.

[0013] In one embodiment of the present disclosure, the first virtualized base station includes a distributed unit.

[0014] In one embodiment of the present disclosure, the scaling configuration entity periodically updates the determination result.

[0015] The present invention discloses a method for automatic adjustment of a virtualized base station, comprising: querying a core network for a user equipment information table, and querying a first reserved resource of a first virtualized base station, wherein the user equipment information table comprises first location information and a first resource requirement corresponding to a first user equipment set; obtaining a second resource requirement corresponding to a second user equipment set from the user equipment information table according to the first location information and a default range, and determining whether the first reserved resource matches the second resource requirement to generate a determination result; and expanding or reducing the first reserved resource of the first virtualized base station according to the determination result.

[0016] Based on the above, the present disclosure can classify the resource requirements of user equipment and perform resource allocation according to the classification results. The present disclosure can avoid the situation where the resource requirements of user equipment cannot be met during the window period caused by the resource configuration of the virtualized base station, thereby reducing the waste of network resources.

[0049] Figure 3A and 3B According to an embodiment of the present disclosure, a schematic diagram of a network management system 100 for automatic adjustment of a virtualized base station (or a virtualized radio access network (vRAN)) is shown. The network management system 100 may include a processor 110 , a storage medium 120 , and a transceiver 130 .

[0050] The processor 110 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose micro control unit (MCU), microprocessor, digital signal processor (DSP), programmable controller, application specific integrated circuit (ASIC), graphics processing unit (GPU), image signal processor (ISP), image processing unit (IPU), arithmetic logic unit (ALU), complex programmable logic device (CPLD), field programmable gate array (FPGA), or other similar elements or combinations thereof. The processor 110 may be coupled to the storage medium 120 and the transceiver 130, and access and execute multiple modules and various applications stored in the storage medium 120.

[0051] The storage medium 120 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), solid state drive (SSD) or similar elements or a combination of the above elements, and is used to store multiple modules or various applications that can be executed by the processor 110. In this embodiment, the storage medium 120 can store multiple modules including a monitoring entity 101, a user equipment information handler 102, a user equipment resource controller 103, a scaling configuration entity 104 and a virtualized radio access network (RAN) management entity 105, and their functions will be described later.

[0052] The transceiver 130 transmits or receives signals in a wireless or wired manner. The transceiver 130 may also perform operations such as low noise amplification, impedance matching, mixing, up or down frequency conversion, filtering, amplification, and the like. The monitoring entity 101 of the network management system 100 may be communicatively connected to the core network via the transceiver 130 to obtain information related to the virtualized base station or user equipment from the core network. In one embodiment, the monitoring entity 101 may be communicatively connected to a unified data management (UDM) function, a policy control function (PCF), a gateway mobile location center (GMLC) function, or a location retrieval function (LRF) in the core network via the transceiver 130. In one embodiment, the virtualized radio access network management entity 105 of the network management system 100 may be communicatively connected to a cloud platform service for managing virtualized base stations via a transceiver 130, wherein the cloud platform service may be used to manage one or more virtualized base stations, wherein the one or more virtualized base stations may include a central unit (CU) or a distributed unit (DU) affiliated with the same central unit. The network management system 100 may instruct the cloud platform service to perform expansion or reduction for the reserved resources of the virtualized base stations via the transceiver 130.

[0053] Figure 4 According to an embodiment of the present disclosure, a flow chart of a method for generating a user equipment information table is shown. The network management system 100 may periodically execute Figure 4 The process is used to generate or update the user equipment information table.

[0054] Specifically, in step S410, the user equipment information processing process 102 may query the unified data management function of the core network for a list of user equipment sets through the monitoring entity 101. Fig. 6A For example, the user equipment information processing process 102 may query the unified data management function for all user equipment in a specific area to obtain a list of user equipment sets, where the user equipment in the list includes user equipment 71, 72, 73, 74, 75, 76 and 77, for example.

[0055] Back to Figure 4In step S420, the user equipment information processing process 102 may query the location information of each user equipment in the list of user equipment sets from the gateway mobile location center function or location search function of the core network through the monitoring entity 101. The location information includes, for example, the distance between the user equipment and the virtualized base station serving the user equipment.

[0056] In step S430, the user equipment information processing process 102 may query the resource requirements of each user equipment in the list of user equipment sets from the policy control function of the core network through the monitoring entity 101. The resource requirements may be represented by resource values, where the resource values ​​may include, for example, service-level agreement (SLA) values, where the SLA values ​​may include information such as bandwidth or latency. It should be noted that the order of step S420 and step S430 may be interchangeable.

[0057] In step S440, the user equipment information processing process 102 may generate a user equipment information table according to the list, location information and resource requirements of the above user equipment set. The user equipment information table may include a list of user equipment, location information of each user equipment and resource requirements of each user equipment.

[0058] Figure 5 According to an embodiment of the present disclosure, a flow chart of a method for performing automatic augmentation is shown. The network management system 100 may periodically perform Figure 5 The process is used to automatically expand or reduce the reserved resources of the virtualized base station.

[0059] In step S510, the scaling configuration entity 104 may obtain a user equipment information table from the user equipment information processing process 102. The scaling configuration entity 104 may obtain a list of user equipments, location information, and resource requirements from the user equipment information table.

[0060] In step S520, the scaling configuration entity 104 may select a user equipment set including one or more user equipments from the list of user equipments according to the location information and the default range, and may obtain resource requirements (e.g., resource values ​​such as SLA values) of the selected user equipments from the user equipment information table, wherein the service range of the virtualized base station is included in the default range. In other words, the default range may be greater than or equal to the service range of the virtualized base station.

[0061] Specifically, the scaling configuration entity 104 may obtain one or more default ranges pre-stored in the UE resource controller 103 from the UE resource controller 103. The scaling configuration entity 104 may determine whether the UE is located in the default range according to the location information of the UE to classify the UE.

[0062] by Fig. 6A For example, the virtualized base station 50 has a service range 51. The scaling configuration entity 104 may set the user equipments (i.e., user equipments 71, 72, and 73) located within the service range 51 to level L1, may set the user equipments (i.e., user equipments 74 and 75) located outside the service range 51 and within the default range 52 to level LX1, and may set the user equipments (i.e., user equipments 76 and 77) located outside the default range 52 and within the default range 53 to level LX2. The scaling configuration entity 104 may generate an information table of the virtualized base station 50 as shown in Table 1 after completing step S510 and step S520.

[0063] Table 1

[0064]

[0065] by Figure 6B For example, the virtualized base station 60 has a service range 61. The scaling configuration entity 104 may set the user equipments (i.e., user equipments 74, 75, and 76) located within the service range 61 to level L1, may set the user equipments (i.e., user equipments 72, 73, and 77) located outside the service range 61 and within the default range 62 to level LX1, and may set the user equipment (i.e., user equipment 71) located outside the default range 62 and within the default range 63 to level LX2. The scaling configuration entity 104 may generate an information table of the virtualized base station 60 as shown in Table 2 after completing step S510 and step S520.

[0066] Table 2

[0067]

[0068] Back to Figure 5 , in step S530, the scaling configuration entity 104 may determine whether the reserved resources of the virtualized base station match the resource requirements corresponding to the user equipment set. Specifically, the user equipment information processing process 102 may query the virtualized base station or the core network for the reserved resources of the virtualized base station through the monitoring entity 101. The user equipment resource controller 103 may pre-store a mapping table, wherein the mapping table may include a mapping relationship between reserved resources and resource values ​​(e.g., SLA values). The scaling configuration entity 104 may convert the reserved resources of the virtualized base station queried by the user equipment information processing process 102 into resource values ​​according to the mapping table. Next, the scaling configuration entity 104 may determine whether the reserved resources of the virtualized base station (i.e., resource values) match the resource requirements of the user equipment set to generate a judgment result. If the judgment result indicates that the reserved resources of the virtualized base station match the resource requirements, the process ends. Figure 5 If the judgment result indicates that the reserved resources of the virtualized base station do not match the resource demand, the process proceeds to step S540.

[0069] In one embodiment, the scaling configuration entity 104 may determine whether the difference between the reserved resources of the virtualized base station and the resource requirements of the user equipment set is greater than a threshold. If the difference is greater than the threshold, the scaling configuration entity 104 may determine that the reserved resources do not match the resource requirements. If the difference is less than or equal to the threshold, the scaling configuration entity 104 may determine that the reserved resources match the resource requirements.

[0070] In step S540, the virtualized radio access network management entity 105 may increase or decrease the reserved resources of the virtualized base station according to the determination result. The virtualized radio access network management entity 105 may transmit an instruction to the cloud platform service through the transceiver 130 to instruct the cloud platform service to increase or decrease the reserved resources of one or more virtualized base stations, wherein the one or more virtualized base stations may include multiple distributed units belonging to the same centralized unit.

[0071] In one embodiment, if the reserved resources of the virtualized base station are greater than the resource requirements of the user equipment set, the virtualized radio access network management entity 105 may instruct the cloud platform service to reduce the reserved resources of the virtualized base station to save network resource overhead. If the reserved resources of the virtualized base station are less than the resource requirements of the user equipment set, the virtualized radio access network management entity 105 may instruct the cloud platform service to expand the reserved resources of the virtualized base station to prepare to serve user equipment that may enter the service range of the virtualized base station in the future.

[0072] The scaling configuration entity 104 and the virtualized radio access network management entity 105 of the network management system 100 may periodically execute Figure 5 The process is used to update the judgment result, and the reserved resources of the virtualized base station are automatically expanded or reduced according to the updated judgment result.

[0073] by Fig. 6AFor example, the scaling configuration entity 104 may select user equipment 71, 72 and 73 with level L1 and user equipment 74 and 75 with level LX1 as the selected user equipment set according to the location information of each user equipment and the default range 52. Next, the scaling configuration entity 104 may determine whether the reserved resources of the virtualized base station 50 match the resource requirements of the selected user equipment set. Referring to Table 1, the resource requirements of user equipment 71, 72, 73, 74 and 75 may include 510M bits per second. If the reserved resources of the virtualized base station 50 exceed 510M bits per second too much, the scaling configuration entity 104 may determine that the reserved resources of the virtualized base station 50 need to be reduced. Accordingly, the virtualized radio access network management entity 105 may instruct the cloud platform service to reduce the bandwidth allocated to the virtualized base station 50. If the reserved resources of the virtualized base station 50 are too much less than 510M bits per second, the scaling configuration entity 104 may determine that the reserved resources of the virtualized base station 50 need to be expanded. Accordingly, the virtualized radio access network management entity 105 may instruct the cloud platform service to expand the bandwidth allocated to the virtualized base station 50 .

[0074] Figure 7 According to an embodiment of the present disclosure, a schematic diagram of increasing or decreasing the reserved resources of a virtualized base station is shown. Fig. 6A and Figure 7 , assuming that the reserved resources of the virtualized base station 50 at the initial time point T1 are 15 gigabits per second (Gbps), and the virtualized base station 50 is used to serve a specific set of user equipment, wherein the user equipment set includes one or more user equipment with level L1, one or more user equipment with level LX1, and one or more user equipment with level LX2. After a period T (i.e., time point T1+T), if the network management system 100 predicts that the resource demand of the user equipment set is 8Gbps in total, the network management system 100 can control the virtualized base station 50 to reduce the reserved resources from 15Gbps to 8Gbps. After another period T (i.e., time point T1+2T), if the network management system 100 predicts that the resource demand of the user equipment set is 12Gbps in total, the network management system 100 can control the virtualized base station 50 to expand the reserved resources from 8Gbps to 12Gbps. After another period T (i.e., time point T1+3T), if the network management system 100 predicts that the resource demand of the user equipment set is 13 Gbps in total, the network management system 100 can control the virtualized base station 50 to increase the reserved resources from 12 Gbps to 13 Gbps. After another period T (i.e., time point T1+4T), if the network management system 100 predicts that the resource demand of the user equipment set is 7.5 Gbps in total, the network management system 100 can control the virtualized base station 50 to reduce the reserved resources from 13 Gbps to 7.5 Gbps.

[0075] Figure 8According to an embodiment of the present disclosure, a flow chart of a method for automatic adjustment of a virtualized base station is shown, wherein the method may be performed as follows: Figure 1 The network management system 100 shown is implemented. In step S810, the user equipment information table is queried from the core network, and the first reserved resources of the first virtualized base station are queried, wherein the user equipment information table includes first location information and first resource requirements corresponding to the first user equipment set. In step S820, the second resource requirements corresponding to the second user equipment set are obtained from the user equipment information table according to the first location information and the default range, and it is determined whether the first reserved resources match the second resource requirements to generate a determination result. In step S830, the first reserved resources of the first virtualized base station are expanded or reduced according to the determination result.

[0076] In summary, the network management system of the present disclosure can predict the amount of resources that the virtualized base station will need to consume in the future based on the location information and resource requirements of the user equipment. The network management system can dynamically adjust the reserved resources of the virtualized base station based on the prediction results, thereby meeting the resource requirements of the user equipment without wasting excess network resources.
