Apparatuses and methods consistent with example embodiments of the present disclosure relate to policy/configuration implementation in an open radio access network (O-RAN) Service Management and Orchestration (SMO) framework.
A radio access network (RAN) is an important component in a telecommunications system, as it connects end-user devices (or user equipment) to other parts of the network. The RAN includes a combination of various network elements (NEs) that connect the end-user devices to a core network. Traditionally, hardware and/or software of a particular RAN is vendor specific.
Open RAN (O-RAN) technology has emerged to enable multiple vendors to provide hardware and/or software to a telecommunications system. To this end, O-RAN disaggregates the RAN functions into a centralized unit (CU), a distributed unit (DU), and a radio unit (RU). The CU is a logical node for hosting Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), and/or Packet Data Convergence Protocol (PDCP) sublayers of the RAN. The DU is a logical node hosting Radio Link Control (RLC), Media Access Control (MAC), and Physical (PHY) sublayers of the RAN. The RU is a physical node that converts radio signals from antennas to digital signals that can be transmitted over the FrontHaul to a DU. Because these entities have open protocols and interfaces between them, they can be developed by different vendors.
The NRT RIC is the control point of a non-real-time control loop and operates on a timescale greater than 1 second within the SMO framework. Its functionalities are implemented through modular applications called rApps (rApp 1, . . . , rApp N in
The nRT RIC operates on a timescale between 10 milliseconds and 1 second and connects to the O-DU, O-CU (disaggregated into the O-CU control plane (O-CU-CP) and the O-CU user plane (O-CU-UP)), and an open evolved NodeB (O-eNB) via the E2 interface. The nRT RIC uses the E2 interface to control the underlying RAN elements (E2 nodes/network functions (NFs)) over a near-real-time control loop. The nRT RIC monitors, suspends/stops, overrides, and controls the E2 nodes (O-CU, O-DU, and O-eNB) via policies. For example, the nRT sets policy parameters on activated functions of the E2 nodes. Further, the nRT RIC hosts xApps to implement functions such as quality of service (QOS) optimization, mobility optimization, slicing optimization, interference mitigation, load balancing, security, etc. The two types of RICs work together to optimize the O-RAN. For example, the NRT RIC provides, over the A1 interface, the policies, data, and artificial intelligence (AI)/machine learning (ML) models enforced and used by the nRT RIC for RAN optimization, and the nRT returns policy feedback (i.e., how the policy set by the NRT RIC works).
The SMO framework, within which the NRT RIC is located, manages and orchestrates RAN elements. Specifically, the SMO manages and orchestrates what is referred to as the O-RAN Cloud (O-Cloud). The O-Cloud is a collection of physical RAN nodes that host the RICs, O-CUs, and O-DUs, the supporting software components (e.g., the operating systems and runtime environments), and the SMO itself. In other words, the SMO manages the O-Cloud from within. The O2 interface is the interface between the SMO and the O-Cloud it resides in. Through the O2 interface, the SMO provides infrastructure management services (IMS) and deployment management services (DMS).
In related art, O-RAN frameworks allow different users to input policies in a form that only a particular constituency of users understand. For example, business users (e.g., users with only a high level understanding of the system operations) may only be capable of writing intent policies using business terms and not system level terms/commands, such as scripting language like JSON, xml, etc. There are currently no specified procedures for optimizing RAN or O-Cloud resources based on internally or externally defined intents.
According to embodiments, systems and methods are provided that enable different users of an open radio access network (O-RAN) to input intent policies.
According to an aspect of the disclosure, a method of generating policies/configurations in an O-RAN service management and orchestration (SMO) framework, the SMO framework including an intent interface termination and a non-real-time RAN intelligent controller (NRT RIC), may include obtaining an input corresponding to an intent policy for at least one operation of the SMO framework, determining the intent policy of the input, generating an SMO policy/configuration based on the intent policy, and implementing the SMO policy/configuration on at least one of a near-real-time RIC (nRT RIC), at least one RAN node, and an O-RAN Cloud (O-Cloud).
According to an aspect of the disclosure, a system for generating policies/configurations in an O-RAN SMO framework, the SMO framework comprising an intent interface termination and a NRT RIC, may include at least one memory storing instructions and at least one processor configured to execute the instructions to obtain an input corresponding to an intent policy for at least one operation of the SMO framework, determine the intent policy of the input, generate an SMO policy/configuration based on the intent policy, and implement the SMO policy/configuration on at least one of a nRT RIC, at least one RAN node, and an O-Cloud.
According to an aspect of the disclosure, a non-transitory computer-readable storage medium may store instructions that, when executed by at least one processor in an O-RAN SMO framework, cause the at least one processor to obtain an input corresponding to an intent policy for at least one operation of the SMO framework, determine the intent policy of the input, generate an SMO policy/configuration based on the intent policy, and implement the SMO policy/configuration on at least one of a nRT RIC, at least one RAN node, and an O-Cloud.

Example embodiments of the present disclosure provide a system in an open radio access network (O-RAN) service management and orchestration (SMO) framework, the SMO framework including an intent interface termination and a non-real-time RAN intelligent controller (NRT RIC), where the system may obtain an input corresponding to an intent policy for at least one operation of the SMO framework, determine the intent policy of the input, generate an SMO policy/configuration based on the intent policy, and implement the SMO policy/configuration on at least one of a near-real-time RIC (nRT RIC), at least one RAN node, and an O-RAN Cloud (O-Cloud). The system may determine an abstraction level of the intent policy, where the abstraction level includes one of a business abstraction level and a system abstraction level. The system may, based on determining the abstraction level of the intent policy as the business abstraction level, translate the intent policy to correspond to at least one system level command.
The system may obtain the input and determine the intent policy by the intent interface termination, and generate the SMO policy/configuration by the NRT RIC. The system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the NRT RIC. The NRT RIC may include an rApp on which a policy management function module is deployed, and the system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the policy management function module that is deployed on the rApp. The NRT RIC may include an rApp and a policy management function module deployed outside of the rApp, and the system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the policy management function module that is not deployed on the rApp.
The systems, methods, devices, etc., disclosed herein allow intent policies to be input from various users of varying types of language, such that SMO policies/configurations may be implemented based on the varying intent policies.
As referred to herein, “intent” and “intent policy” may be used interchangeably to refer to at least one intended policy/result that is input in the O-RAN system.
The input creator 502 may include a set of authorized entities including the user, the application (e.g., an rApp), an operations support system (OSS), a business support system (BSS), orchestrator external entities, etc. that may create an intent policy. The intent creator 502 may submit the intent policy to the SMO framework 504 through a dedicated external reference point terminated at the SMO framework 504 (e.g., intent interface termination 506).
The intent interface termination 506 may terminate the intent interface in the SMO framework 504. The intent interface termination 506 may expose details of application programming interfaces (APIs) for intent determination and translation available in the NRT RIC 508. The intent interface termination 506 may receive an intent policy from intent creator 502 and the convert/forward the intent policy to the NRT RIC 508.
The NRT RIC 508 may include an intent parser 520, a syntactic and semantic analyzer 522, a conflict resolution module 524, an intent compilation module 526, an intent abstraction module 528, and a policy management function module 530.
The intent parser 520 may be is responsible for the initial parsing of the obtained intent policy. The intent parser 520 may perform lexical analysis, token generation, and syntactic analysis, etc., In the event of an error occurring during the parsing process, appropriate error messages may be sent to the intent creator 502, and the SMO framework 504 may record the errors for further analysis.
The syntactic and semantic analyzer 522 may provide meaning to the output of the intent parser 520. Examples include datatype checking, array bounds checking, proper declaration of variables, scope resolution, etc. The syntactic and semantic analyzer 522 may generate gist and keywords to provide additional knowledge to other functional blocks. In the event of an error occurring during this process, error messages may be sent to the intent creator 502.
The conflict resolution module 524 may check if the current intent policy conflicts with any existing policies. Upon detection of a conflict, the conflict resolution module 524 may inform the intent creator 502 of the conflict, while also providing details of the policy conflict.
The intent compilation module 526 may be configured to compile the intent in a format that is understood by the O-RAN architecture 500.
The intent abstraction module 528 may identify the abstraction level of the input intent policy. The intent abstraction module 528 may define the target output abstraction level, as well as the types of output configuration parameters, based on the semantics of the intent policy, the gist and keywords, and the input abstraction level. For instance, an end user may input an intent policy to improve video streaming quality without supplying any technical details, and the intent abstraction module 528 may be configured to identify the abstraction level of the input intent policy as a business abstraction level. As another example, an end user may input an intent policy to improve video streaming quality while supplying any technical details, and the intent abstraction module 528 may be configured to identify the abstraction level of the input intent policy as a system abstraction level. The intent abstraction module 528 may be configured to determine whether one or more translations are required between the input and output abstraction levels. Once the current abstraction level has successfully completed, the intent abstraction module 528 may determine whether another abstraction level translation is required, or whether the process is complete. When another abstraction level translation is required, the intent abstraction module 528 may return control to the intent parser 520 with new instructions. When no further abstraction level translations are required, the completed Intent Policy may be sent to the intent compilation module 526.
The policy management function module 530 may manage the compiled intent policy to generate policies or configurations for a near-RT RIC (nRT RIC), RAN nodes (e.g., RAN node 512), and/or the O-Cloud (e.g., O-Cloud 514). The policy management function module 530 may verify, validate, and authorize policies/configurations. The policy management function module 530 may create polices/configurations for the nRT RIC based on the received intent. Based on an abstraction level, the policy management function module 530 may determine to create policies or direct configurations for RAN nodes (e.g., RAN node 512), and/or the O-Cloud (e.g., O-Cloud 514). For example, when a throughput requirement for video streaming is provided in the intent policy, the intent policy may be determined to be of a system abstraction level, where the policy management function module 530 may directly provide configurations to RAN Nodes. Alternatively, when the intent policy only mentions basic or general video quality streaming parameters, such as 480p, 1080p, etc., the intent policy may be determined to be of a business abstraction level, which may require a looped policy to maintain desired video quality. Thus, the policy management function module 530 may determine key performance indicators (KPIs) to monitor to implement the intent policy. That is, if the intent policy is provided on low, engineering level (e.g., system level commands or parameters), and the policy management function module 530 may generate a policy/configuration for the intent policy and implement the generated policy/configuration without intent abstraction.
As shown in
In the example shown in
As shown in
As shown in
The system may utilize various factors to determine which framework to use of those described with respect to
The system may consider targets for the intent policies. The targets may include RAN nodes, nRT RICs, O-Cloud and/or SMO/NRT RIC frameworks. When the intent policy targets RAN nodes, nRT RICs, O-Clouds, etc., the system may implement frameworks 600, 700 and/or 800 due to the involvement of the rApp through which the operator is provided more control over targeted elements. When the intent policy targets a management system, such at the SMO, NRT RIC, etc., then framework 900 may be deployed, as in framework 900, the reliability and availability of the system may be managed within the platform. For example, availability and reliability of the NFO/FOCOM may be very important and the intent creator may pass high level objectives (e.g. business level of abstraction). However, the platform may manage itself after receiving the intent policy to produce policies or configurations required to maintain availability and reliability of the system.
The system may determine an abstraction level or class of the intent policies as is described above. A business level intent policy may require framework to generate a policy from a primitive stage due to a lack of key indicators in the intent policy. Thus, the rApp may process this as a compiled intent and create policy/configurations using the AIML workflow services. A system level intent policy may include more detailed information, such as key indicators, target nodes, etc. Thus, the platform may host most of the intent framework functionality, and the rApp may optionally help derive actual configurations for the nodes.
O-RAN architecture defines the NRT RICE as SMO internal functionality. However, some operators may choose to have NRT RIC as a standalone solution (e.g., providing a private 5th generation (5G) network may have NFO/FOCOM from a cloud service provider due to a small network, however, such scenarios require the NRT RIC to manage RAN resources through the Non-RT RIC). In this scenario, most or all of the intent framework may be integrated with the NRT RIC platform, as shown in frameworks 700, 800 and 900.
The system may determine an abstraction level of the intent policy, where the abstraction level includes one of a business abstraction level and a system abstraction level. The system may, based on determining the abstraction level of the intent policy as the business abstraction level, translate the intent policy to correspond to at least one system level command.
The system may obtain the input and determine the intent policy by the intent interface termination, and generate the SMO policy/configuration by the NRT RIC. The system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the NRT RIC. The NRT RIC may include an rApp on which a policy management function module is deployed, and the system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the policy management function module that is deployed on the rApp. The NRT RIC may include an rApp and a policy management function module deployed outside of the rApp, and the system may obtain the input by the intent interface termination, and determine the intent policy and generate the SMO policy/configuration by the policy management function module that is not deployed on the rApp.
The systems, methods, devices, etc., disclosed herein allow intent policies to be input from various users of varying types of language, such that SMO policies/configurations may be implemented based on the varying intent policies.

For example, user device 1110 may include a computing device (e.g., a desktop computer, a laptop computer, a tablet computer, a handheld computer, a smart speaker, a server, etc.), a mobile phone (e.g., a smart phone, a radiotelephone, etc.), a wearable device (e.g., a pair of smart glasses or a smart watch), or a similar device. In some implementations, user device 1110 may receive information from and/or transmit information to platform 1120.
Platform 1120 includes one or more devices capable of receiving, generating, storing, processing, and/or providing information. In some implementations, platform 1120 may include a cloud server or a group of cloud servers. In some implementations, platform 1120 may be designed to be modular such that certain software components may be swapped in or out depending on a particular need. As such, platform 1120 may be easily and/or quickly reconfigured for different uses.
In some implementations, as shown, platform 1120 may be hosted in cloud computing environment 1122. Notably, while implementations described herein describe platform 1120 as being hosted in cloud computing environment 1122, in some implementations, platform 1120 may not be cloud-based (i.e., may be implemented outside of a cloud computing environment) or may be partially cloud-based.
Cloud computing environment 1122 includes an environment that hosts platform 1120. Cloud computing environment 1122 may provide computation, software, data access, storage, etc. services that do not require end-user (e.g., user device 1110) knowledge of a physical location and configuration of system(s) and/or device(s) that hosts platform 1120. As shown, cloud computing environment 1122 may include a group of computing resources 1124 (referred to collectively as “computing resources 1124” and individually as “computing resource 1124”).
Computing resource 1124 includes one or more personal computers, a cluster of computing devices, workstation computers, server devices, or other types of computation and/or communication devices. In some implementations, computing resource 1124 may host platform 1120. The cloud resources may include compute instances executing in computing resource 1124, storage devices provided in computing resource 1124, data transfer devices provided by computing resource 1124, etc. In some implementations, computing resource 1124 may communicate with other computing resources 1124 via wired connections, wireless connections, or a combination of wired and wireless connections.
As further shown in
Application 1124-1 includes one or more software applications that may be provided to or accessed by user device 1110.

For example, application 1124-1 may include software associated with platform 1120 and/or any other software capable of being provided via cloud computing environment 1122. In some implementations, one application 1124-1 may send/receive information to/from one or more other applications 1124-1, via virtual machine 1124-2.

A system virtual machine may provide a complete system platform that supports execution of a complete operating system (“OS”). A process virtual machine may execute a single program, and may support a single process. In some implementations, virtual machine 1124-2 may execute on behalf of a user (e.g., user device 1110), and may manage infrastructure of cloud computing environment 1122, such as data management, synchronization, or long-duration data transfers.
Virtualized storage 1124-3 includes one or more storage systems and/or one or more devices that use virtualization techniques within the storage systems or devices of computing resource 1124. In some implementations, within the context of a storage system, types of virtualizations may include block virtualization and file virtualization. Block virtualization may refer to abstraction (or separation) of logical storage from physical storage so that the storage system may be accessed without regard to physical storage or heterogeneous structure. The separation may permit administrators of the storage system flexibility in how the administrators manage storage for end users. File virtualization may eliminate dependencies between data accessed at a file level and a location where files are physically stored. This may enable optimization of storage use, server consolidation, and/or performance of non-disruptive file migrations.
Hypervisor 1124-4 may provide hardware virtualization techniques that allow multiple operating systems (e.g., “guest operating systems”) to execute concurrently on a host computer, such as computing resource 1124. Hypervisor 1124-4 may present a virtual operating platform to the guest operating systems, and may manage the execution of the guest operating systems. Multiple instances of a variety of operating systems may share virtualized hardware resources.

The number and arrangement of components shown in
In embodiments, any one of the operations or processes of
The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the implementations to the precise form disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practice of the implementations.
Some embodiments may relate to a system, a method, and/or a computer readable medium at any possible technical detail level of integration. Further, one or more of the above components described above may be implemented as instructions stored on a computer readable medium and executable by at least one processor (and/or may include at least one processor). The computer readable medium may include a computer-readable non-transitory storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out operations.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program code/instructions for carrying out operations may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects or operations.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer readable media according to various embodiments. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). The method, computer system, and computer readable medium may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the Figures. In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed concurrently or substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
It will be apparent that systems and/or methods, described herein, may be implemented in different forms of hardware, firmware, or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the implementations. Thus, the operation and behavior of the systems and/or methods were described herein without reference to specific software code—it being understood that software and hardware may be designed to implement the systems and/or methods based on the description herein.
