The subject matter disclosed herein relates generally to wireless communications and more particularly relates to improving confidence of network analytics using a digital twin.
In certain wireless communication systems, a consumer of a network analytics function can request a specific confidence of analytics and a time to report the analytics, e.g., report analytics within an hour time frame. The request can be a subscription or a one-time request. If the network analytics function cannot report the analytics in the specific time period with the specific confidence level the network analytics function will respond with an error indicating that the analytics cannot be provided. In addition, the network analytics function may indicate to the consumer to end the subscription for analytics. The consumer will then need to query a different network analytics function and identify if such analytics can be provided with the specific requirements.

Generally, the present disclosure describes systems, methods, and apparatus for improving confidence of network analytics using a digital twin. In certain embodiments, the methods may be performed using computer code embedded on a computer-readable medium. In certain embodiments, an apparatus or system may include a computer-readable medium containing computer-readable code which, when executed by a processor, causes the apparatus or system to perform at least a portion of the below described solutions.
Digital twins are a new concept that is gaining attention in the tech industry. Supported by artificial intelligence, digital twins allow data-driven networks to utilize the immerse data available in a network and create a “digital mirror” of a physical entity that can run in parallel and simulate the physical entity functions.
Digital twins are already used to some degree in some network deployments. For example, in industrial internet of things (“IIoT”) networks, digital twins are used for preventative maintenance where a digital twin of a manufacturing equipment is created in order to predict failure scenarios and estimate the optimal time that the equipment would need to be replaced. A digital twin uses raw data provided by the corresponding physical entity to estimate, predict, forecast, or the like the physical entity's future functions, performance, and/or the like.
Use of digital twins in 5G networks have not been fully addressed and are in the early stages of discussion. However, for example, the IIOT industry in 5G-ACIA has published research on how the industry visualizes a digital twin 5G network. One example is in industrial networks described in 5G-ACIA where a digital twin is used to simulate whether a 5G network can support the time sensitive requirements from an industrial network. 5G-ACIA has defined an 5G Asset Administrator Shell (“AAS”) to create digital twins for a 5G network.
5G-ACIA has defined two digital twins for the 5G system a 5G UE digital twin (5G UE AAS) and a 5G network digital twin (5G Network AAS). The 5G Network AAS is able to simulate its performance assuming specific topology, PDU session/QoS flow scenarios. The digital twin uses an AI/ML model to simulate the performance, taking into account raw “live” data from the physical 5G network using a dedicated API.
From the 3GPP perspective, 3GPP has not yet fully evaluated how the Digital Twin paradigm can improve the network operations/functionality. This disclosure addresses how the digital twin paradigm can be used on the network analytics provided by a 3GPP network.
In one implementation, the RAN 120 is compliant with the 5G system specified in the Third Generation Partnership Project (“3GPP”) specifications. For example, the RAN 120 may be a NG-RAN, implementing NR RAT and/or LTE RAT. In another example, the RAN 120 may include non-3GPP RAT (e.g., Wi-Fi® or Institute of Electrical and Electronics Engineers (“IEEE”) 802.11-family compliant WLAN). In another implementation, the RAN 120 is compliant with the LTE system specified in the 3GPP specifications. More generally, however, the wireless communication system 100 may implement some other open or proprietary communication network, for example Worldwide Interoperability for Microwave Access (“WiMAX”) or IEEE 802.16-family standards, among other networks. The present disclosure is not intended to be limited to the implementation of any particular wireless communication system architecture or protocol.
In one embodiment, the remote units 105 may include computing devices, such as desktop computers, laptop computers, personal digital assistants (“PDAs”), tablet computers, smart phones, smart televisions (e.g., televisions connected to the Internet), smart appliances (e.g., appliances connected to the Internet), set-top boxes, game consoles, security systems (including security cameras), vehicle on-board computers, network devices (e.g., routers, switches, modems), or the like. In some embodiments, the remote units 105 include wearable devices, such as smart watches, fitness bands, optical head-mounted displays, or the like. Moreover, the remote units 105 may be referred to as the UEs, subscriber units, mobiles, mobile stations, users, terminals, mobile terminals, fixed terminals, subscriber stations, user terminals, wireless transmit/receive unit (“WTRU”), a device, or by other terminology used in the art. In various embodiments, the remote unit 105 includes a subscriber identity and/or identification module (“SIM”) and the mobile equipment (“ME”) providing mobile termination functions (e.g., radio transmission, handover, speech encoding and decoding, error detection and correction, signaling and access to the SIM). In certain embodiments, the remote unit 105 may include a terminal equipment (“TE”) and/or be embedded in an appliance or device (e.g., a computing device, as described above).
In one embodiment, the remote units 105 may include computing devices, such as desktop computers, laptop computers, personal digital assistants (“PDAs”), tablet computers, smart phones, smart televisions (e.g., televisions connected to the Internet), smart appliances (e.g., appliances connected to the Internet), set-top boxes, game consoles, security systems (including security cameras), vehicle on-board computers, network devices (e.g., routers, switches, modems), or the like. In some embodiments, the remote units 105 include wearable devices, such as smart watches, fitness bands, optical head-mounted displays, or the like. Moreover, the remote units 105 may be referred to as UEs, subscriber units, mobiles, mobile stations, users, terminals, mobile terminals, fixed terminals, subscriber stations, user terminals, wireless transmit/receive unit (“WTRU”), a device, or by other terminology used in the art.
The remote units 105 may communicate directly with one or more of the cellular base units 121 in the 3GPP access network 120 via uplink (“UL”) and downlink (“DL”) communication signals. Furthermore, the UL and DL communication signals may be carried over the 3GPP communication links 123. Similarly, the remote units 105 may communicate with one or more access points 131 in the non-3GPP access network(s) 130 via UL and DL communication signals carried over the non-3GPP communication links 133. Here, the access networks 120 and 130 are intermediate networks that provide the remote units 105 with access to the mobile core network 140.
In some embodiments, the remote units 105 communicate with a remote host (e.g., in the data network 150 or in the data network 160) via a network connection with the mobile core network 140. For example, an application 107 (e.g., web browser, media client, telephone and/or Voice-over-Internet-Protocol (“VoIP”) application) in a remote unit 105 may trigger the remote unit 105 to establish a protocol data unit (“PDU”) session (or other data connection) with the mobile core network 140 via the 5G-RAN 115 (i.e., via the 3GPP access network 120 and/or non-3GPP network 130). The mobile core network 140 then relays traffic between the remote unit 105 and the remote host using the PDU session. The PDU session represents a logical connection between the remote unit 105 and a User Plane Function (“UPF”) 141.
In order to establish the PDU session (or PDN connection), the remote unit 105 must be registered with the mobile core network 140 (also referred to as “attached to the mobile core network” in the context of a Fourth Generation (“4G”) system). Note that the remote unit 105 may establish one or more PDU sessions (or other data connections) with the mobile core network 140. As such, the remote unit 105 may have at least one PDU session for communicating with the packet data network 150. Additionally—or alternatively—the remote unit 105 may have at least one PDU session for communicating with the packet data network 160. The remote unit 105 may establish additional PDU sessions for communicating with other data networks and/or other communication peers.
In the context of a 5G system (“5GS”), the term “PDU Session” refers to a data connection that provides end-to-end (“E2E”) user plane (“UP”) connectivity between the remote unit 105 and a specific Data Network (“DN”) through the UPF 131. A PDU Session supports one or more Quality of Service (“QoS”) Flows. In certain embodiments, there may be a one-to-one mapping between a QoS Flow and a QoS profile, such that all packets belonging to a specific QoS Flow have the same 5G QoS Identifier (“5QI”).
In the context of a 4G/LTE system, such as the Evolved Packet System (“EPS”), a Packet Data Network (“PDN”) connection (also referred to as EPS session) provides E2E UP connectivity between the remote unit and a PDN. The PDN connectivity procedure establishes an EPS Bearer, i.e., a tunnel between the remote unit 105 and a Packet Gateway (“PGW”, not shown) in the mobile core network 130. In certain embodiments, there is a one-to-one mapping between an EPS Bearer and a QoS profile, such that all packets belonging to a specific EPS Bearer have the same QoS Class Identifier (“QCI”).
As described in greater detail below, the remote unit 105 may use a first data connection (e.g., PDU Session) established with the first mobile core network 130 to establish a second data connection (e.g., part of a second PDU session) with the second mobile core network 140. When establishing a data connection (e.g., PDU session) with the second mobile core network 140, the remote unit 105 uses the first data connection to register with the second mobile core network 140.
The cellular base units 121 may be distributed over a geographic region. In certain embodiments, a cellular base unit 121 may also be referred to as an access terminal, a base, a base station, a Node-B (“NB”), an Evolved Node B (abbreviated as eNodeB or “eNB,” also known as Evolved Universal Terrestrial Radio Access Network (“E-UTRAN”) Node B), a 5G/NR Node B (“gNB”), a Home Node-B, a Home Node-B, a relay node, a device, or by any other terminology used in the art. The cellular base units 121 are generally part of a radio access network (“RAN”), such as the 3GPP access network 120, that may include one or more controllers communicably coupled to one or more corresponding cellular base units 121. These and other elements of radio access network are not illustrated but are well known generally by those having ordinary skill in the art. The cellular base units 121 connect to the mobile core network 140 via the 3GPP access network 120.
The cellular base units 121 may serve a number of remote units 105 within a serving area, for example, a cell or a cell sector, via a 3GPP wireless communication link 123. The cellular base units 121 may communicate directly with one or more of the remote units 105 via communication signals. Generally, the cellular base units 121 transmit DL communication signals to serve the remote units 105 in the time, frequency, and/or spatial domain. Furthermore, the DL communication signals may be carried over the 3GPP communication links 123. The 3GPP communication links 123 may be any suitable carrier in licensed or unlicensed radio spectrum. The 3GPP communication links 123 facilitate communication between one or more of the remote units 105 and/or one or more of the cellular base units 121. Note that during NR operation on unlicensed spectrum (referred to as “NR-U”), the base unit 121 and the remote unit 105 communicate over unlicensed (i.e., shared) radio spectrum.
The non-3GPP access networks 130 may be distributed over a geographic region. Each non-3GPP access network 130 may serve a number of remote units 105 with a serving area. An access point 131 in a non-3GPP access network 130 may communicate directly with one or more remote units 105 by receiving UL communication signals and transmitting DL communication signals to serve the remote units 105 in the time, frequency, and/or spatial domain. Both DL and UL communication signals are carried over the non-3GPP communication links 133. The 3GPP communication links 123 and non-3GPP communication links 133 may employ different frequencies and/or different communication protocols. In various embodiments, an access point 131 may communicate using unlicensed radio spectrum. The mobile core network 140 may provide services to a remote unit 105 via the non-3GPP access networks 130, as described in greater detail herein.
In some embodiments, a non-3GPP access network 130 connects to the mobile core network 140 via an interworking entity 135. The interworking entity 135 provides an interworking between the non-3GPP access network 130 and the mobile core network 140. The interworking entity 135 supports connectivity via the “N2” and “N3” interfaces. As depicted, both the 3GPP access network 120 and the interworking entity 135 communicate with the AMF 143 using a “N2” interface. The 3GPP access network 120 and interworking entity 135 also communicate with the UPF 141 using a “N3” interface. While depicted as outside the mobile core network 140, in other embodiments the interworking entity 135 may be a part of the core network. While depicted as outside the non-3GPP RAN 130, in other embodiments the interworking entity 135 may be a part of the non-3GPP RAN 130.
In certain embodiments, a non-3GPP access network 130 may be controlled by an operator of the mobile core network 140 and may have direct access to the mobile core network 140. Such a non-3GPP AN deployment is referred to as a “trusted non-3GPP access network.” A non-3GPP access network 130 is considered as “trusted” when it is operated by the 3GPP operator, or a trusted partner, and supports certain security features, such as strong air-interface encryption. In contrast, a non-3GPP AN deployment that is not controlled by an operator (or trusted partner) of the mobile core network 140, does not have direct access to the mobile core network 140, or does not support the certain security features is referred to as a “non-trusted” non-3GPP access network. An interworking entity 135 deployed in a trusted non-3GPP access network 130 may be referred to herein as a Trusted Network Gateway Function (“TNGF”). An interworking entity 135 deployed in a non-trusted non-3GPP access network 130 may be referred to herein as a non-3GPP interworking function (“N3IWF”). While depicted as a part of the non-3GPP access network 130, in some embodiments the N3IWF may be a part of the mobile core network 140 or may be located in the data network 150.
In one embodiment, the mobile core network 140 is a 5G core (“5GC”) or the evolved packet core (“EPC”), which may be coupled to a data network 150, like the Internet and private data networks, among other data networks. A remote unit 105 may have a subscription or other account with the mobile core network 140. Each mobile core network 140 belongs to a single public land mobile network (“PLMN”). The present disclosure is not intended to be limited to the implementation of any particular wireless communication system architecture or protocol.
The mobile core network 140 includes several network functions (“NFs”). As depicted, the mobile core network 140 includes at least one UPF (“UPF”) 141. The mobile core network 140 also includes multiple control plane functions including, but not limited to, an Access and Mobility Management Function (“AMF”) 143 that serves the 5G-RAN 115, a Session Management Function (“SMF”) 145, a Policy Control Function (“PCF”) 146, an Authentication Server Function (“AUSF”) 147, a Unified Data Management (“UDM”) and Unified Data Repository function (“UDR”).
The UPF(s) 141 is responsible for packet routing and forwarding, packet inspection, QoS handling, and external PDU session for interconnecting Data Network (“DN”), in the 5G architecture. The AMF 143 is responsible for termination of NAS signaling, NAS ciphering & integrity protection, registration management, connection management, mobility management, access authentication and authorization, security context management. The SMF 145 is responsible for session management (i.e., session establishment, modification, release), remote unit (i.e., UE) IP address allocation & management, DL data notification, and traffic steering configuration for UPF for proper traffic routing.
The PCF 146 is responsible for unified policy framework, providing policy rules to CP functions, access subscription information for policy decisions in UDR. The AUSF 147 acts as an authentication server.
The UDM is responsible for generation of Authentication and Key Agreement (“AKA”) credentials, user identification handling, access authorization, subscription management. The UDR is a repository of subscriber information and can be used to service a number of network functions. For example, the UDR may store subscription data, policy-related data, subscriber-related data that is permitted to be exposed to third party applications, and the like. In some embodiments, the UDM is co-located with the UDR, depicted as combined entity “UDM/UDR” 149.
In one embodiment, the mobile core network 140 includes a network analytics function (“NAF”) 180 that collects data from UEs, network functions, OAM systems, and/or the like from the mobile network 140, 5G core network (“CN”), and cloud that can be used for analytics related to the wireless communication system 100. Various NAF sources, functions, domains, or the like in 3GPP may be used including management data analytics service (“MDAS”), network data analytics function (“NWDAF”), analytics data application services (“ADAES”), and/or the like, which are described in more detail below.
In one embodiment, the mobile core network 140 may include a digital twin controller function (“DTCF”) 182, which allows creation/instantiation of a digital twin of a physical entity, and a network repository function (“NRF”) 184, which allows discovery of a DTCF 182, digital twin instances, and/or the like, within the mobile core network 140.
In various embodiments, the mobile core network 140 may also include an Network Exposure Function (“NEF”) (which is responsible for making network data and resources easily accessible to customers and network partners, e.g., via one or more APIs), a Network Repository Function (“NRF”) (which provides NF service registration and discovery, enabling NFs to identify appropriate services in one another and communicate with each other over Application Programming Interfaces (“APIs”)), or other NFs defined for the 5GC. In certain embodiments, the mobile core network 140 may include an authentication, authorization, and accounting (“AAA”) server.
In various embodiments, the mobile core network 140 supports different types of mobile data connections and different types of network slices, wherein each mobile data connection utilizes a specific network slice. Here, a “network slice” refers to a portion of the mobile core network 140 optimized for a certain traffic type or communication service. A network instance may be identified by a S-NSSAI, while a set of network slices for which the remote unit 105 is authorized to use is identified by NSSAI. In certain embodiments, the various network slices may include separate instances of network functions, such as the SMF and UPF 141. In some embodiments, the different network slices may share some common network functions, such as the AMF 143. The different network slices are not shown in
Although specific numbers and types of network functions are depicted in

The Operations, Administration and Maintenance (“OAM”) 162 is involved with the operating, administering, managing, and maintaining of the system 100. “Operations” encompass automatic monitoring of environment, detecting and determining faults and alerting admins. “Administration” involves collecting performance stats, accounting data for the purpose of billing, capacity planning using Usage data and maintaining system reliability. Administration can also involve maintaining the service databases which are used to determine periodic billing. “Maintenance” involves upgrades, fixes, new feature enablement, backup and restore and monitoring the media health. In certain embodiments, the OAM 162 may also be involved with provisioning, i.e., the setting up of the user accounts, devices, and services.
As depicted, a remote unit 105 (e.g., a UE) may connect to the mobile core network (e.g., to a 5G mobile communication network) via two types of accesses: (1) via 3GPP access network 120 and (2) via a non-3GPP access network 130. The first type of access (e.g., 3GPP access network 120) uses a 3GPP-defined type of wireless communication (e.g., NG-RAN) and the second type of access (e.g., non-3GPP access network 130) uses a non-3GPP-defined type of wireless communication (e.g., WLAN). The 5G-RAN 115 refers to any type of 5G access network that can provide access to the mobile core network 140, including the 3GPP access network 120 and the non-3GPP access network 130.
In one embodiment, the solution proposed herein may be performed by, for example, a network device that includes a network function, an OAM 162, an application function, a function within an enablement layer, and/or the like. In one embodiment, as described above, network analytics can be provided by different domains in 3GPP. In one embodiment, network analytics may be provided in 3GPP by an MDAS (SA5) that provides data analytics for the network. MDAS can be deployed at different levels, for example, at domain level (e.g., RAN, CN, network slice subnet) or in a centralized manner (e.g., in a PLMN level). The objective of MDAS is to optimize the management plane (in network/domain level, in slice/slice subnet level) by performing analytics based on network management data. Such service can be exposed to the 3rd party/MDAS service consumer to provide performance management (“PM”) analytics, fault management (“FM”) analytics, network slice instance (“NSI”)/network slice subnet instance (“NSSI”) analytics, optionally recommend appropriate management actions e.g., scaling of resources, admission control, load balancing of traffic, and/or the like.
In one embodiment, network analytics may be provided in 3GPP by an NWDAF (SA2), provides several analytics services which include the UE/network performance:
In one embodiment, network analytics may be provided in 3GPP by an ADAES (SA6), provides application data analytics services (stats/predictions) to optimize the application service operation by notifying the application specific layer, and potentially 5GS, for expected/predicted application service parameters changes considering both on-network and off-network deployments (e.g., related to application QoS parameters).
In one embodiment, a consumer of such analytics may request that the analytics (predictions) have a specific confidence level. The network analytics function (either MDAS, NWDAF or ADAES) may not provide analytics to the consumer until the confidence level is reached or satisfied. This may require the network analytics function to use as many samples as possible when collecting raw data from the respective data producer NFs to ensure that the confidence level is reached.
There may be scenarios where the network analytics function may not have enough samples available to reach the confidence level required. In such scenarios, use of digital twins can improve the confidence level by leveraging the digital twin to provide additional samples in order to improve the confidence level of the analytics.
In addition, the network data analytics functions in 3GPP do not have a mechanism defined to identify if the prediction is accurate, e.g., there is no feedback mechanism. Use of digital twins may allow such functions to determine, via a digital twin, if a prediction is accurate by, for example, running simulations of NF load and determine if a predicted NF load at a specific time of day is accurate.
The subject matter disclosed herein addresses the following solutions:
In general, the solutions discussed herein support an architecture where a network data analytics function (e.g., NWDAF, MDAS, ADAES) can dynamically trigger digital twin instances to collect additional raw data in order to improve analytics.
A new Digital Twin Controller Function (“DTCF”) is proposed to be introduced within the 5G Core Network that allows creation/instantiation of a digital twin of a physical entity. The digital twin can be a physical entity of a complete 5G network, a specific slice (composed of RAN and core network elements), a specific RAN, or a specific core network slice or can be a twin of a specific Network Function type (e.g., AMF type). In one embodiment, the DTCF manages the resources required for the digital twins.
In one embodiment, the solutions herein improve the confidence of analytics by collecting additional samples from digital twin instance. In such an embodiment, when a network analytics function determines that additional samples are required to improve the confidence of analytics, the network analytics function requests to identify a digital twin of the physical network function from the DTCF.
The network analytics function, in one embodiment, identifies from the NRF the DTCF that is aware of the required digital twin instance that corresponds to the physical NF associated with the analytics. In one embodiment, the request to the DTCF can include a request to identify a digital twin for a network slice, a request to identify a digital twin for an NF instance, and/or the like.
In one embodiment, the request to the DTCF includes additional parameters (filters) in order for the DTCF to identify the parameters requires to run the digital twin. The parameters may include a number of UEs served, NF load, a number of MM connections (e.g., to an AMF), a number of SM connections (e.g., to an SMF), a number of PDU sessions/QoS flows (e.g., to an SMF/UPF), a deployment or topology (in case a digital twin slice instance is created), and/or a combination of the foregoing.
In one embodiment, the DTCF provides an identifier of the digital twin instance to the network analytics function to allow the function to interface with the digital twin instance to obtain the additional data.
At step 1 (see block 314), in one embodiment, a consumer NF 302 determines that it needs analytics with a specific confidence level.
At step 2 (see messaging 316), in one embodiment, the consumer NF 302 requests analytics from the NAF 304. The request may include a specific confidence level to be reached/satisfied before the NAF 304 provides the analytics. The consumer NF 302 may also include a time period/time frame when these analytics are required for delivery.
At steps 3 and 4 (see blocks 318 and 320), in one embodiment, the NAF 304 collects the data required for the analytics by subscribing to corresponding Event IDs, e.g., as described in 3GPP TS 23.288.
At step 5 (see block 322), in one embodiment, the NAF 304 determines that there are not enough samples, data points, or the like to reach/satisfy the required confidence level at the specific time.
At step 6 (see block 324), in one embodiment, the NAF 304 determines if there are available digital twin instances of the data producer NF instances in order to collect additional samples for the missing data.
At step 7 (see messaging 326), in one embodiment, the NAF 304 interfaces with an NRF 308 to discover a DTCF 310 that has an available digital twin NF instance/slice instance. The NAF 304, in one embodiment, includes in the request the NF type or slice type required for the digital twin.
At step 8 (see messaging 328), in one embodiment, the NRF 308 checks if there is a DTCF 310 that supports the digital twin instance required. The DTCF 310, in one embodiment, registers to the NRF 308 the available digital twin instances, e.g., the DTCF 310 has already configured simulation models for such digital twin instances.
At step 9, (see messaging 330), in one embodiment, the NAF 304 interfaces with the DTCF 310 and requests the DTCF 310 via a new service based interface (“SBI”) to run a digital twin instance with specific simulation parameters (e.g., assuming a specific number of UEs served, a specific number of MM or SM sessions active, and/or the like). The NAF 304, in one embodiment, determines the simulation parameters according to the missing data to achieve the required confidence level.
At step 10 (see block 332), in one embodiment, the DTCF 310 runs the digital twin instance according to the simulation parameters
At step 11 (see messaging 334), in one embodiment, the DTCF 310 responds to the NAF 304 with an identifier for the digital twin instance.
At step 12 (see block 336), in one embodiment, the NAF 304 maps the digital twin instance ID to the physical instance of the network function 306.
At step 13 (see block 338), in one embodiment, the NAF 304 obtains data from the digital twin instance 312 using a data collection procedure, e.g., the data collection procedure defined in 3GPP TS 23.288. In an alternative embodiment the NAF 304 interacts with the DTCF 310 in order to obtain data for a digital twin instance. In such a scenario, the DTCF 310 interfaces with the digital twin instance with a procedure not described in 3GPP (e.g., a procedure that is implementation based).
At step 14 (see block 340), in one embodiment, the NAF 304 derives analytics with the required confidence level using the additional data obtained from the digital twin instance 312 and sends it to the consumer NF 302.
In one embodiment, the NAF 304 may also request instantiation of a digital twin of a UE to receive missing samples. In such an embodiment, the procedures described in
In one embodiment, the DTCF creates digital twin instances based on a pre-configuration or based on a configuration provided by an OAM. In one embodiment, other network functions may request creation of a digital twin instances. In one embodiment, the DTCF invokes a digital twin as shown in
At step 1 (see block 410), in one embodiment, the DTCF 402 receives a request to create a digital twin for an NF type (e.g., AMF, SMF) or a slice type (e.g., S-NSSAI). The request may come from the OAM, the NAF, or a data collection coordination function (“DCCF”), described below. The request may include specific simulation parameters (e.g., number of UEs served, number of MM/SM sessions, and/or the like). The request may be received by a new SBI including an identifier to describe the type of digital twin required (e.g., AMF twin, SMF twin, slice instance twin, and/or the like).
At step 2 (see block 412), in one embodiment, the DTCF 402 determines the AI/ML model required to run the digital twin instances. The DTCF 402 may interact with a ML model provider function to receive the required model.
At step 3 (see block 414), in one embodiment, according to the request in step 1, the DTCF 402 determines the physical NF 406 to obtain real time data in order to run the digital twin instance. For example, if the request is to run an AMF type for a specific “physical” AMF, the DTCF 402 collects data from the physical AMF.
At step 4 (see block 416), in one embodiment, the DTCF 402 creates the digital twin instance.
At step 5 (see block 418), in one embodiment, the DTCF 402 obtains real time data from the identified physical NFs 406. In this embodiment, the DTCF 402 interfaces with the digital twin instance with a procedure not described in 3GPP e.g., (a procedure that is implementation based). In an alternative embodiment, the digital twin instance may directly interact with the physical instance to obtain real time data.
At step 6 (see block 420), in one embodiment, the DTCF 402 registers the created digital twin instance with the NRF 408. The DTCF 402, in one embodiment, may also request instantiation of a digital twin of a UE to receive missing samples. In such an embodiment, the procedures described in
In an alternative embodiment, the consumer of a DTCF can be a DCCF. The DCCF may determine that the data requested by a consumer may not be available (either historical data or real time data). The DCCF in that case may request the DTCF to run a digital twin instance in order to obtain the required data. In an alternative embodiment, the consumer may also include an indication that data is allowed to be obtained from a digital twin data producer.
At step 1 (see block 512), in one embodiment, a consumer NF 502 determines that it needs analytics with a specific confidence level.
At step 2 (see messaging 514), in one embodiment, the consumer NF 502 requests analytics from the DCCF 504. The data may be identified by a specific Event ID, e.g., as described in 3GPP TS 23.288.
At step 3 (see block 516), in one embodiment, the DCCF 504 determines that data for the Event ID are not available. This may be due, e.g., for privacy reasons that the Data Producer NF cannot report the data.
At step 4 (see block 518), in one embodiment, the DCCF 504 determines if there are available digital twin instances of the Data producer NF instances in order to collect additional samples for missing data.
At step 5 (see messaging 520), in one embodiment, the DCCF 504 interfaces with an NRF 506 to discover a DTCF 508 that has an available digital twin NF Instance/Slice instance. The DCCF 504 may include in the request the NF type or slice type required for the digital twin.
At step 6 (see messaging 522), in one embodiment, the NRF 506 checks if there is a DTCF 508 that supports the digital twin instance required. The DTCF 508 registers to the NRF 506 the available digital twin instances (e.g., the DTCF 508 has already configured simulation model for such digital twin instances).
At step 7 (see messaging 524), in one embodiment, the DCCF 504 interfaces with the DTCF 508 and requests the DTCF 508 via a new SBI to run a digital twin instance with specific simulation parameters (e.g., assume specific number of UEs served, specific number of MM or SM sessions active, and/or the like). The NAF determines the simulation parameters according to the missing data to achieve the required confidence level.
At step 8 (see block 526), in one embodiment, the DTCF 508 runs the digital twin instance 510 according to the simulation parameters.
At step 9, (see messaging 528), in one embodiment, the DTCF 508 responds to the DCCF 504 with the identifier for the digital twin instance.
At step 10 (see block 530), in one embodiment, the DCCF 504 maps the digital twin instance ID to the physical instance of the corresponding NF.
At step 11 (see block 532), in one embodiment, the DCCF 504 obtains data from the digital twin instance 510 using a data collection procedure, e.g., as defined in 3GPP TS 23.288. In an alternative embodiment, the DCCF 504 interacts with the DTCF 508 in order to obtain data for a digital twin instance 510. In such a scenario, the DTCF 508 interfaces with the digital twin instance 510 with a procedure not described in 3GPP (e.g., a procedure that is implementation based).
At step 12 (see messaging 534), in one embodiment, the DCCF 504 reports the data to the consumer NF 502 or stores the data, e.g., in an analytics data repository function (“ADRF”).
The DCCF 504 may also request instantiation of a digital twin of a UE to receive missing samples. In such an embodiment, the procedure described in
In a second embodiment, the digital twin instances can be utilized by a consumer to determine the confidence level provided by a network analytics function. In one embodiment, the consumer may be the network analytics functions in order to derive the confidence level of an analytic prediction. For example, when a network data analytics function derives an analytics predictions for load for an NF instance, the function may instantiate a digital instance of the NF instance to determine the accuracy of the prediction.
In general, the DTCF, as described above in embodiment 1, is utilized to request/identify digital twin instance of a physical NF instance. In one embodiment, the procedure shown in
At step 1 (see block 614), in one embodiment, a consumer NF 602 determines that it needs analytics with a specific confidence level.
At step 2 (see messaging 616), in one embodiment, the consumer NF 602 requests analytics from the NAF 604. The request may include a specific confidence level to be reached/satisfied before the NAF 604 provides the analytics. The consumer NF 602 may also include a time period/time frame when these analytics are required for delivery. The request may also include an indication for analytics feedback that is used by the network analytics function to determine if a digital twin instance is required to be invoked.
At steps 3 and 4 (see blocks 618 and 620), in one embodiment, the NAF 604 collects the data required for the analytics by subscribing to corresponding Event IDs, e.g., as described in 3GPP TS 23.288.
At step 5 (see block 622), in one embodiment, the NAF 604 determines to derive a confidence level from a digital twin instance 612 or alternatively derives a confidence level and requests feedback from the digital twin instance 612 to confirm that the prediction is correct.
At step 6 (see block 624), in one embodiment, the NAF 304 determines if there are available digital twin instances 612 of the data producer NF instances in order to collect additional samples for missing data.
At step 7 (see messaging 626), in one embodiment, the NAF 604 interfaces with an NRF 608 to discover a DTCF 610 that has an available digital twin NF instance/slice instance 612. The NAF 604, in one embodiment, includes in the request the NF type or slice type required for the digital twin 612.
At step 8 (see messaging 628), in one embodiment, the NRF 608 checks if there is a DTCF 610 that supports the digital twin instance required. The DTCF 610, in one embodiment, registers to the NRF 608 the available digital twin instances, e.g., the DTCF 610 has already configured simulation models for such digital twin instances.
At step 9, (see messaging 630), in one embodiment, the NAF 304 interfaces with the DTCF 310 and requests the DTCF 310 via a new service based interface (“SBF”) to run a digital twin instance with specific simulation parameters (e.g., assuming a specific number of UEs served, a specific number of MM or SM sessions active, and/or the like). The NAF 604, in one embodiment, determines the simulation parameters according to the missing data to achieve the required confidence level.
At step 10 (see block 632), in one embodiment, the DTCF 610 runs the digital twin instance 612 according to the simulation parameters
At step 11 (see messaging 634), in one embodiment, the DTCF 610 responds to the NAF 304 with an identifier for the digital twin instance 612.
At step 12 (see block 636), in one embodiment, the NAF 604 maps the digital twin instance ID to the physical instance of the network function 606.
At step 13 (see block 638), in one embodiment, the NAF 604 obtains data from the digital twin instance 612 using a data collection procedure, e.g., the data collection procedure defined in 3GPP TS 23.288. In an alternative embodiment the NAF 604 interacts with the DTCF 610 in order to obtain data for a digital twin instance 612. In such a scenario, the DTCF 610 interfaces with the digital twin instance 612 with a procedure not described in 3GPP (e.g., a procedure that is implementation based).
At step 14 (see block 640), in one embodiment, the NAF 604 derives analytics with the required confidence level using the additional data obtained from the digital twin instance 612 and/or receives feedback whether the predicted confidence level is accurate.
In one embodiment, the consumer may also request a digital twin instance 612 to validate the accuracy of an analytics prediction. In such case, the procedure in
