The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, algorithm, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

In some embodiments, artificial intelligence/machine learning (AI/ML) helps to solve problems with iterative processing and feedback. For example, a typical machine learning pipeline may include the following processes:

• Data collection.

• Data cleaning.

• Feature extraction (labelling and dimensionality reduction).

• Model validation.

This forms a processing pipeline which is different from the Sendee Function Chaining (SFC). SFC is to form a traffic path with an ordered sequence of virtualized network function (VNFs) and subsequent steering of flows through them to provide end-to-end services. Orchestration Pipeline defines a logical flow of activities or tasks from a Start event to an End event to accomplish a specific service. The event driven the tasks are generally data centric such as availability of the data, periodically update of the data; parallel data processing.

In a cloud native environment, the orchestration of a workload is already very challenging due to the requirements such as QoS, computing resource, communication, and triggers among the sub-tasks in the pipeline. In the 6 Generation (6G) cloud native system, UE related events such as mobility, network status such as wireless channel conditions, congestion can also affect the pipeline logic.

Among other things, embodiments of the present disclosure present solutions to the following problems:

• How to describe the context information related to a service pipeline.

• How to enhance a service orchestration chaining function (SOCF) framework to provide service pipelining for UE, application function (AF) or network functions (NFs).

• How to negotiate the triggers across computing, communication and data planes to set up triggers.

While there are existing tools that provide APIs to allow data scientists to specify the pipeline and manage models, deployments, these existing tools consider only the data centers environment and AI/ML application in an IT domain which cannot be directly applied to the distributed 6G wide-area cloud where a processing pipeline can be partitioned across multiple network nodes, e.g., located in UE, RAN, CN, Edge and Cloud. Additionally, these tools lack the awareness of UE, PDU session, network status, network function capabilities etc. so that the data related process such as data collection, transfer, processing and delivery is not considered.

Embodiments of the present disclosure, by contrast, address these and other issues.

Example embodiments of the present disclosure relate to systems, methods, and devices for pipelining services in next-generation cellular networks.

The mechanisms to enable service pipeline is proposed. First, the context information related to service pipeline service is identified which can be exchanged among UE/AF/SOCF and other related functions to describe the pipeline logic, the requirements and triggers about the service pipeline. Second, the SOCF services are enhanced to allow UE, AF and other NF to create/update/delete a service pipeline. Then the messages flows among SOCF, Comp/Comm/Data CFs/SFs, other NFs can handle the triggers for each task in the pipeline.

The above descriptions are for purposes of illustration and are not meant to be limiting. Numerous other examples, configurations, processes, algorithms, etc., may exist, some of which are described in greater detail below. Example embodiments will now be described with reference to the accompanying figures.

FIG. 1 depicts an illustrative schematic diagram for pipelining services, in accordance with one or more example embodiments of the present disclosure.

The service pipeline context information is the information to describe the pipeline service and its requirements from the service consumer, which can also be exchanged in the 6G system to convey to the related functions such as Comp/Comm/Data CFs/SFs for orchestration and configuration. The service pipeline context information includes but not limited to

Pipeline ID: the pipeline ID is generated by the 6G system and sent to UE to identify a pipeline service. This pipeline ID can be used similar to a SFC service ID and generated by SOCF or policy control function (PCF). The pipeline ID can be used for classification of the pipeline related user traffic from UE. For example, this classification can be in terms of QoS within a PDU session or without a PDU session for a sub-processing.

Pipeline template: the pipeline template is to describe the pipeline service modules and logic. Pipeline template type comprises the network can provide a processing pipeline template based on general user intent to process a data set, e.g., classification. Pipeline template type comprises the processing modules can also be specified or provided by a UE or AF, e.g., by XML or YAML files. Descriptions for each tasks in the workflow and how the tasks related to each other in form of a graph. For example, the tasks could be processing data, training a model, hyperparameter tuning, evaluation, and model deployment for AIML service. Related data identifiers for each task as input or output. For example, the identifier can be URI towards the data in data storage or data filters that can be used to search related data in a data repository'.

Orchestration requirements: the derived requirements on each pod/containe r for a task such as resource, comp capabilities, and location. The QoS for the workflow or sub-workflow including communication requirements such as GBR, non-GBR, latency, response time, etc, service requirements such as training time, etc. data requirements such as integrity ⁷ , distribution. Triggers: triggers include the events or intermediate results that can change the processing pipeline. For example, availability of the data, periodically updated data, or parallel processing data.

SOCF Pipeline Service: in some embodiments, pipeline service-related operations (in bold) can be added to existing SOCF services as shown in Table 1. Table 1 : SOCF Service Operations:

Note that there can be a service based interface (SBI) between UE and SOCF to request pipeline service. If there is no direct interface, UE can communicate to SOCF via AMF similar to 5G or via CU-CP if N2 evolves into SBI. AF can consume SOCF service via NEF.

Message Flow for Pipeline Service: the sen ice consumer for SOCF pipeline sendee (Table 1) can be UE. AF (e.g., viaNEF) or NFs that can request pipeline service following the message flow in FIG. 1.

1) UE or application function (AF) (via NEF) or NF sends a Nsocf_CreatePipelineContext request to request pipeline service with SOCF. This message shall include the pipeline service context information as described in 5. 1.1. In one embodiment, UE can request pipeline service after a valid registration with the network via a SBI between UE and SOCF. If there is no direct SBI between UE and SOCF, UE can request pipeline sendee via AMF or CU-CP. In another embodiment, AF can request pipeline service via NEF. In another embodiment, NF can request pipeline service viaNsocf.

2) SOCF generates the requirements on Comp/Comm/Data planes for the pipeline service based on the pipeline service context received in Step 1. In one embodiment, SOCF can choose the Comp/Comm/Data CF instances based on the requested location in the pipeline service context. In another embodiment, SOCF can choose the Comp/Comm/Data CF instances based on the location of the data in the pipeline service context, which may involve parsing a FQDN related to the identifier of the data with a DNS. In another embodiment, SOCF can choose the Comp/Comm/Data CF instances based on the deployment of a sub-task in the processing pipeline which may involve querying service registry function (SRF) for a specific service instance. In another embodiment, SOCF can choose the Comp/Comm/Data CF instances based on their reported occupancy and response time. Multiple Comp/Comm/Data CFs can be selected.

3) In some embodiments, the SOCF sends a Npcf_pipelinePolicy_create request to PCF if the PCF is responsible to generate a subset or all of the policies related to the pipeline service including the pipeline ID. In one embodiment, SOCF can request the pipeline ID generation similar to a SFC service ID. In another embodiment, SOCF can generate and manage the pipeline IDs.

4) In some embodiments, the PCF generates the pipeline ID and policies as requested. The related policy can be mobility related to a UE. For example, PCF can generate a location areas that the UE is limited to based on the pipeline requirements indicated by SOCF. This policy may be sent to AMF which can send a trigger to the request SOCF for UE’s mobility change.

5) In some embodiments, the PCF sends a Npcf_pipelinePolicy_create response to SOCF to indicate the results of the pipeline ID and policy generation. PCF shall send the pipeline ID as well as the related policies.

6) SOCF sends a context request create to Comp/Comm/Data CFs via Ncompcf, Ncommcf, Ndatacf, which are the interfaces of Comp CF, Comm CF and Data CF. This request shall include : a. The service pipeline ID and related service pipeline context information. For example, the request to Comp CF can include the compute resources such as CPU, memory, HW/SW capabilities, etc. required for the tasks in the service pipeline. b. The additional rules to select a Comp/Comm/Data SFs. c. The identifiers of the Comp/Comm/Data CFs for these control functions to contact each other on setting up triggers for the tasks in the pipeline. d. The movement of the data for easy data access to guarantee QoS.

7) The Comp/Comm/Data CFs can select and configure the Comp/Comm/Data SFs based on the information received from SOCF. Comp CF can schedule the tasks in the pipeline which is implementation specific. In one example, if the trigger to the task is based on the availability of the data identified with a URI, the Comp CF shall subscribe to the update of the data to the Data CF. In another example, the Comp CF can subscribe to a UE’s mobility events which can be a trigger to start a task in the pipeline. In another example, Comm CF (e.g., session management function (SMF)) can request to set up a PDU session between UE and a Comp SF or Data SF. The PDU session may be associated with the pipeline ID.

8) The Comp/Comm/Data CFs send the context create responses to SOCF to indicate the results of the pipeline generation and configuration. A failure cause may be included if the request is not processed successfully.

9) SOCF sends Nsocf_CreatePipelineContext response with the pipeline ID and configurations to the tasks if some tasks in the pipeline run on the UE and set up triggers to the tasks. In one or more embodiments, a pipelining services system may facilitate that the pipeline service context information to describe the pipeline logic, tasks and triggers, where the triggers include the events or intermediate results that can change the processing pipeline: availability of the data; periodically updated data; or parallel processing data.

FIGs. Error! Reference source not found.-Error! Reference source not found, illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.

FIG. 3 illustrates an example network architecture 300 according to various embodiments. The network 300 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other netyvorks that benefit from the principles described herein, such as future 3GPP systems, or the like.

The network 300 includes a UE 302, which is any mobile or non-mobile computing device designed to communicate yvith a RAN 304 via an over-the-air connection. The UE 302 is communicatively coupled with the RAN 304 by a Uu interface, which may be applicable to both LTE and NR systems. Examples of the UE 302 include, but are not limited to, a smartphone, tablet computer, wearable computer, desktop computer, laptop computer, in- vehicle infotainment system, in-car entertainment system, instrument cluster, head-up display (HUD) device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electron! c/engine control unit, electronic/ engine control module, embedded system, sensor, microcontroller, control module, engine management system, netyvorked appliance, machine-type communication device, machine-to-machine (M2M), device-to-device (D2D), machine-ty pe communication (MTC) device, Internet of Things (loT) device, and/or the like. The network 300 may include a plurality of UEs 302 coupled directly with one another via a D2D, ProSe. PC5, and/or sidelink (SL) interface. These UEs 302 may be M2M/D2D/MTC/IoT devices and/or vehicular systems that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc. The UE 302 may perform blind decoding attempts of SL channels/links according to the various embodiments herein.

In some embodiments, the UE 302 may additionally communicate with an AP 306 via an over-the-air (OTA) connection. The AP 306 manages a WLAN connection, which may serve to offload some/all network traffic from the RAN 304. The connection between the UE 302 and the AP 306 may be consistent with any IEEE 802.11 protocol. Additionally, the UE 302, RAN 304, and AP 306 may utilize cellular- WLAN aggregation/integration (e.g., LWA/LWIP). Cellular- WLAN aggregation may involve the UE 302 being configured by the RAN 304 to utilize both cellular radio resources and WLAN resources.

The RAN 304 includes one or more access network nodes (ANs) 308. The ANs 308 terminate air-interface(s) for the UE 302 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and PHY/L1 protocols. In this manner, the AN 308 enables data/voice connectivity ⁷ between CN 320 and the UE 302. The ANs 308 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells; or some combination thereof. In these implementations, an AN 308 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, etc.

One example implementation is a “CU/DU split’' architecture where the ANs 308 are embodied as a gNB-Central Unit (CU) that is communicatively coupled with one or more gNB- Distributed Units (DUs), where each DU may be communicatively coupled with one or more Radio Units (RUs) (also referred to as RRHs, RRUs, or the like) (see e.g., 3GPP TS 38.401 v 16.1.0 (2020-03)). In some implementations, the one or more RUs may be individual RSUs. In some implementations, the CU/DU split may include an ng-eNB-CU and one or more ng- eNB-DUs instead of, or in addition to, the gNB-CU and gNB-DUs, respectively. The ANs 308 employed as the CU may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network including a virtual Base Band Unit (BBU) or BBU pool, cloud RAN (CRAN), Radio Equipment Controller (REC), Radio Cloud Center (RCC), centralized RAN (C-RAN), virtualized RAN (vRAN), and/or the like (although these terms may refer to different implementation concepts). Any other ty pe of architectures, arrangements, and/or configurations can be used.

The plurality of ANs may be coupled with one another via an X2 interface (if the RAN 304 is an LTE RAN or Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 310) or an Xn interface (if the RAN 304 is a NG-RAN 314). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.

The ANs of the RAN 304 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 302 with an air interface for network access. The UE 302 may be simultaneously connected with a plurality of cells provided by the same or different ANs 308 of the RAN 304. For example, the UE 302 and RAN 304 may use carrier aggregation to allow the UE 302 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN 308 may be a master node that provides an MCG and a second AN 308 may be secondary node that provides an SCG. The first/second ANs 308 may be any combination of eNB, gNB, ng-eNB, etc.

The RAN 304 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.

In V2X scenarios the UE 302 or AN 308 may be or act as a roadside unit (RSU), which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an '‘eNB-type RSU’’; a gNB may be referred to as a '‘gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e g., Ethernet) to a traffic signal controller or a backhaul network.

In some embodiments, the RAN 304 may be an E-UTRAN 310 with one or more eNBs 312. The an E-UTRAN 310 provides an LTE air interface (Uu) with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on C SIRS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.

In some embodiments, the RAN 304 may be an next generation (NG)-RAN 314 with one or more gNB 316 and/or on or more ng-eNB 318. The gNB 316 connects with 5G-enabled UEs 302 using a 5G NR interface. The gNB 316 connects with a 5GC 340 through an NG interface, which includes an N2 interface or an N3 interface. The ng-eNB 318 also connects with the 5GC 340 through an NG interface, but may connect with a UE 302 via the Uu interface. The gNB 316 and the ng-eNB 318 may connect with each other over an Xn interface.

In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 314 and a UPF 348 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN 314 and an AMF 344 (e.g., N2 interface).

The NG-RAN 314 may provide a 5G-NR air interface (which may also be referred to as a Uu interface) with the following characteristics: variable SCS; CP-OFDM for DL, CP- OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G-NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.

The 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 302 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 302, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 302 with different amount of frequency ⁷ resources (e.g., PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 302 and in some cases at the gNB 316. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.

The RAN 304 is communicatively coupled to CN 320 that includes network elements and/or network functions (NFs) to provide various functions to support data and telecommunications services to customers/subscribers (e.g., UE 302). The components of the CN 320 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 320 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 320 may be referred to as a network slice, and a logical instantiation of a portion of the CN 320 may be referred to as a network sub-slice.

The CN 320 may be an LTE CN 322 (also referred to as an Evolved Packet Core (EPC) 322). The EPC 322 may include MME 324, SGW 326, SGSN 328, HSS 330, PGW 332, and PCRF 334 coupled with one another over interfaces (or “reference points”) as shown. The NFs in the EPC 322 are briefly introduced as follows.

The MME 324 implements mobility management functions to track a current location of the UE 302 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.

The SGW 326 terminates an SI interface toward the RAN 310 and routes data packets between the RAN 310 and the EPC 322. The SGW 326 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3 GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

The SGSN 328 tracks a location of the UE 302 and performs security functions and access control. The SGSN 328 also performs inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 324; MME 324 selection for handovers; etc. The S3 reference point between the MME 324 and the SGSN 328 enable user and bearer information exchange for inter-3GPP access network mobility' in idle/active states.

The HSS 330 includes a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 330 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 330 and the MME 324 may enable transfer of subscription and authentication data for authenticating/ authorizing user access to the EPC 320. The PGW 332 may terminate an SGi interface toward a data network (DN) 336 that may include an application (app)Zcontent server 338. The PGW 332 routes data packets between the EPC 322 and the data network 336. The PGW 332 is communicatively coupled with the SGW 326 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 332 may further include a node for policy enforcement and charging data collection (e.g., PCEF). Additionally, the SGi reference point may communicatively couple the PGW 332 with the same or different data network 336. The PGW 332 may be communicatively coupled with a PCRF 334 via a Gx reference point.

The PCRF 334 is the policy and charging control element of the EPC 322. The PCRF 334 is communicatively coupled to the app/content server 338 to determine appropriate QoS and charging parameters for service flows. The PCRF 332 also provisions associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.

The CN 320 may be a 5GC 340 including an AUSF 342, AMF 344, SMF 346, UPF 348, NSSF 350, NEF 352, NRF 354, PCF 356, UDM 358, and AF 360 coupled with one another over various interfaces as shown. The NFs in the 5GC 340 are briefly introduced as follows.

The AUSF 342 stores data for authentication of UE 302 and handle authentication- related functionality. The AUSF 342 may facilitate a common authentication framework for various access types..

The AMF 344 allows other functions of the 5GC 340 to communicate with the UE 302 and the RAN 304 and to subscribe to notifications about mobility events with respect to the UE 302. The AMF 344 is also responsible for registration management (e.g., for registering UE 302), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 344 provides transport for SM messages between the UE 302 and the SMF 346, and acts as a transparent proxy for routing SM messages. AMF 344 also provides transport for SMS messages between UE 302 and an SMSF. AMF 344 interacts with the AUSF 342 and the UE 302 to perform various security anchor and context management functions. Furthermore, AMF 344 is a termination point of a RAN-CP interface, which includes the N2 reference point between the RAN 304 and the AMF 344. The AMF 344 is also a termination point of NAS (Nl) signaling, and performs NAS ciphering and integrity protection.

AMF 344 also supports NAS signaling with the UE 302 over an N3IWF interface. The N3IWF provides access to untrusted entities. N3IWF may be a termination point for the N2 interface between the (R)AN 304 and the AMF 344 for the control plane, and may be a termination point for the N3 reference point between the (R)AN 314 and the 348 for the user plane. As such, the AMF 344 handles N2 signalling from the SMF 346 and the AMF 344 for PDU sessions and QoS, encapsulate/de-encapsulate packets for IPSec and N3 tunnelling, marks N3 user-plane packets in the uplink, and enforces QoS corresponding to N3 packet marking taking into account QoS requirements associated with such marking received overN2. N3IWF may also relay UL and DL control-plane NAS signalling between the UE 302 and AMF 344 via an N1 reference point between the UE 302and the AMF 344, and relay uplink and downlink user-plane packets between the UE 302 and UPF 348. The N3IWF also provides mechanisms for IPsec tunnel establishment with the UE 302. The AMF 344 may exhibit an Narnf sendeebased interface, and may be a termination point for an N14 reference point betw een two AMFs 344 and an N17 reference point between the AMF 344 and a 5G-EIR (not shown by FIG. 3).

The SMF 346 is responsible for SM (e.g., session establishment, tunnel management between UPF 348 and AN 308); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 348 to route traffic to proper destination: termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 344 over N2 to AN 308; and determining SSC mode of a session. SM refers to management of a PDU session, and a PDU session or "session" refers to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 302 and the DN 336.

The UPF 348 acts as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data netw ork 336, and a branching point to support multihomed PDU session. The UPF 348 also performs packet routing and forwarding, packet inspection, enforces user plane part of policy rules, lawfully intercept packets (UP collection), performs traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), performs uplink traffic verification (e.g., SDF-to-QoS flow mapping), transport level packet marking in the uplink and downlink, and performs downlink packet buffering and downlink data notification triggering. UPF 348 may include an uplink classifier to support routing traffic flows to a data network.

The NSSF 350 selects a set of network slice instances serving the UE 302. The NSSF 350 also determines allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 350 also determines an AMF set to be used to serve the UE 302, or a list of candidate AMFs 344 based on a suitable configuration and possibly by querying the NRF 354. The selection of a set of network slice instances for the UE 302 may be triggered by the AMF 344 with which the UE 302 is registered by interacting with the NSSF 350; this may lead to a change of AMF 344. The NSSF 350 interacts with the AMF 344 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown).

The NEF 352 securely exposes services and capabilities provided by 3GPP NFs for third party, internal exposure/re-exposure. AFs 360. edge computing or fog computing systems (e.g., edge compute node, etc. In such embodiments, the NEF 352 may authenticate, authorize, or throttle the AFs. NEF 352 may also translate information exchanged with the AF 360 and information exchanged with internal network functions. For example, the NEF 352 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 352 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 352 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 352 to other NFs and AFs, or used for other purposes such as analytics.

The NRF 354 supports service discovery functions, receives NF discovery requests from NF instances, and provides information of the discovered NF instances to the requesting NF instances. NRF 354 also maintains information of available NF instances and their supported services. The NRF 354 also supports service discovery functions, wherein the NRF 354 receives NF Discovery Request from NF instance or an SCP (not shown), and provides information of the discovered NF instances to the NF instance or SCP.

The PCF 356 provides policy rules to control plane functions to enforce them, and may also support unified policy framework to govern network behavior. The PCF 356 may also implement a front end to access subscription information relevant for policy decisions in a UDR of the UDM 358. In addition to communicating with functions over reference points as shown, the PCF 356 exhibit an Npcf service-based interface.

The UDM 358 handles subscription-related information to support the network entities’ handling of communication sessions, and stores subscription data of UE 302. For example, subscription data may be communicated via an N8 reference point between the UDM 358 and the AMF 344. The UDM 358 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 358 and the PCF 356, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 302) for the NEF 352. The Nudr servicebased interface may be exhibited by the UDR 221 to allow the UDM 358, PCF 356, and NEF 352 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM-FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobihty management, and subscription management. In addition to communicating with other NFs over reference points as show n, the UDM 358 may exhibit the Nudm service-based interface.

AF 360 provides application influence on traffic routing, provide access to NEF 352, and interact with the policy framework for policy control. The AF 360 may influence UPF 348 (re)selection and traffic routing. Based on operator deployment, when AF 360 is considered to be a trusted entity, the network operator may permit AF 360 to interact directly with relevant NFs. Additionally, the AF 360 may be used for edge computing implementations,

The 5GC 340 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 302 is attached to the network. This may reduce latency and load on the netw ork. In edge computing implementations, the 5GC 340 may select a UPF 348 close to the UE 302 and execute traffic steering from the UPF 348 to DN 336 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 360, which allows the AF 360 to influence UPF (re)selection and traffic routing.

The data network (DN) 336 may represent various network operator services, Internet access, or third party' services that may be provided by one or more servers including, for example, application (app)/content server 338. The DN 336 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. In this embodiment, the app serv er 338 can be coupled to an IMS via an S-CSCF or the I-CSCF. In some implementations, the DN 336 may represent one or more local area DNs (LADNs), which are DNs 336 (or DN names (DNNs)) that is/are accessible by a UE 302 in one or more specific areas. Outside of these specific areas, the UE 302 is not able to access the LADN/DN 336.

Additionally or alternatively, the DN 336 may be an Edge DN 336, which is a (local) Data Netw ork that supports the architecture for enabling edge applications. In these embodiments, the app server 338 may represent the physical hardware systems/devices providing app server functionality and/or the application software resident in the cloud or at an edge compute node that performs server function(s). In some embodiments, the app/content server 338 provides an edge hosting environment that provides support required for Edge Application Server's execution.

In some embodiments, the 5GS can use one or more edge compute nodes to provide an interface and offload processing of wireless communication traffic. In these embodiments, the edge compute nodes may be included in, or co-located with one or more RAN310, 314. For example, the edge compute nodes can provide a connection between the RAN 314 and UPF 348 in the 5GC 340.
