BACKGROUND
Modem cloud computing has become extremely popular to provide computing/storage capability to customers who can focus more on the SW development and data management without worrying too much about the underlying infrastructure. Edge computing is believed to extend this capability close to the customers to optimize performance metrics such as latency. The 5G architecture design take these scenarios into considerations and developed multi-homing, ULCL framework to offload compute tasks to different data networks (DNs), which may be at the network edge. For the UE with limited computing capabilities, the application can be rendered at the cloud/edge for computing offloading based on application level logic above OS.

DETAILED DESCRIPTION
The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various
aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A or B” and “A/B” mean (A), (B), or (A and B).
With the trend of Telco network cloudification, the cellular network is foreseen to be built with flexibility and scalability by virtualized network functions (VNFs) or containerized network functions (CNFs) running on general purpose hardware. Heterogenous computing capabilities provided by hardware and software, naturally coming with this trend, can be leveraged to provide augmented computing to end devices across device and network. These computing tasks generally have different requirements in resource and dependencies in different scenarios. For example, it can be an application instance either standalone or serving one or more UEs. It can also be a generic function like Al training or inference or a micro-service function using specific accelerators. In addition, the computing task can be semi-static or dynamically launched. To enable these scenarios, this disclosure proposes solutions to enable augmented computing across the device and RAN in order to dynamically offload workload and execute compute tasks at the network computing infrastructure with low latency and better computing scaling.
SESSION ESTABLISHMENT FOR COMPUTE OFFLOAD SERVICES IN 6G SYSTEMS
Among other things, embodiments of the present disclosure are directed to solutions to enhance the 5GS for supporting session establishment for augmented computing and dynamic workload migration. In particular, some embodiments are directed to supporting session establishment for compute offload services. Other embodiments may be described and/or claimed.
There are a variety of advantages of providing computing either as a new service or as a network capability based on different scenarios. First, the computing tasks can be completed at the network edge to optimize latency. This latency includes communication latency as well as the compute task launch and execution latency. Second, the end device can augment the computing by providing requirements about the computing environment and the compute task. Third, the resource efficiency and latency can also be optimized using paradigms like serverless computing to handle more dynamic workload. Embodiments of the present disclosure help enable the UE to establish a session for Compute offload services provided by the 5GS.
Figure 1 illustrates an example of an architecture reference model of the 5G System Architecture which is used as a baseline for the proposed enhancements. Figure 2 illustrates an evolution of the 5GS architecture towards support for augmented computing and dynamic workload migration.
Once the UE wants to offload a computing task to the network it needs to establish a session for compute offload services. This disclosure proceeds by describing the following three embodiments for supporting session establishment for compute offload services:
- Embodiment 1: New RAN Compute offload (RCo) session establishment procedure
• New RCo NAS protocol is introduced for exchanging RCo NAS messages between UE and RAN Compute CF.
• RCo NAS messages are embedded in RCo NAS containers and transferred using RRC messages (e.g. RRCSetupComplete or new RRC message). RAN CU-CP forwards the RCo NAS containers to RAN Compute CF.
• A new RRC establishment cause value of “mo-cmp” for RAN Compute is introduced as part of the RRCSetupRequest message.
• UE initiates RCo session establishment procedure by sending RCo session establishment request. The RCo session parameters are:
- RAN compute session ID used to identify a RAN compute session within a UE
- Compute offload Network Slice Selection Assistance Information (C-NSSAD: used to assist the network to select a slice for compute offload service.
- Compute Data Network Name (CDNN): used to identify Data network for compute offload services.
- Compute Offload Capability (COC): The Compute offload capabilities requested by the UE based on allowed compute offload capabilities indicated by the network during registration procedure.
• RAN CU-CP selects a RAN Compute CF e.g. based on C-NSSAI.
• RAN Compute CF creates SM association with PCF e.g. for charging services.
• RAN Compute CF selects RAN Compute SF e.g. based on COC, CDNN and C-NSSAI.
• RAN Compute SF terminates the user-plane and provides compute offload services to the UE.
- Embodiment 2: N1 PDU Session establishment procedure enhanced for compute offload services.
UE initiates N1 PDU session establishment procedure with the following new PDU session parameters:
- New Request Type - “RCo PDU session”
- RAN compute session ID used to identify a RAN compute session within a UE. As an alternative the existing PDU session ID could be reused as RAN compute session ID.
- Compute offload Slice Network Selection Assistance Information (C-NSSAD: used to assist the network to select a slice for compute offload service.
- Compute Data Network Name (CDNN): used to identify Data network for compute offload services.
- Compute Offload Capability (COC): The Compute offload capabilities requested by the UE based on allowed compute offload capabilities indicated by the network during registration procedure.
• SMF uses new NGAP procedures to manage RCo services provided by the RAN Compute CF/SF (no PDU session is established at UPF).
• RAN CU-CP selects a RAN Compute CF e.g. based on C-NSSAI
• RAN Compute CF selects RAN Compute SF based on C-NSSAI, COC, CDNN and the status of the RAN Compute SF.
• SMF uses NGAP PDU session management procedures enhanced with new session parameters to assign resources on Uu and UP for the RCo PDU session, and to setup corresponding DRBs. New session parameters are: RAN compute session ID, C-NSSAI, CDNN, COC and endpoint information specific to the RAN Compute SF.
• RAN Compute SF terminates the user-plane and provides compute offload services to the UE.

The RAN Compute CF includes the endpoint information (e.g. RAN Compute SF identifier) in the response.
The RAN CU-CP forwards N2 RCo session establishment response to the AMF.
7. The AMF initiates the SM Policy Association Modification procedure with the PCF (e.g. a Policy control request trigger is met related to charging policy).
8.
The AMF sends N2 RCo session request (new NGAP procedure) to the RAN CU- CP. The AMF includes the C-NSSAI, CDNN and COC and endpoint information. The AMF also includes the N1 SM container with the RCo session establishment accept. The RCo Session Establishment Accept includes the C-NSSAI, CDNN and COC.
9. The RAN CU-CP establishes the required radio bearers and connects the user plane with the RAN Compute SF based on the endpoint information. The RAN CU-CP forwards NAS RCo session establishment accept to the UE.
TRUSTED THIRD PARTY BASED END-TO-END (E2E) APPLICATION SECURITY FOR COMPUTE OFFLOAD
Augmented computing across UE and RAN or dynamic workload offloading allows a compute task to be dynamically offloaded and executed on the network computing infrastructure with low latency and better computing scaling. With the trend of Telco network cloudification, the cellular network is foreseen to be built with flexibility and scalability by virtualized network functions (VNFs) or containerized network functions (CNFs) running on general-purpose hardware. Heterogenous computing capabilities provided by hardware and software, naturally coming with this trend, can be leveraged to provide augmented computing to end devices across devices and networks. These computing tasks generally have different requirements in resources and dependencies in different scenarios. For example, it can be an application instance either standalone or serving one or more UEs. It can also be a generic function like Al training or inference or a micro-service function using specific accelerators. Besides, the computing task can be semi-static or dynamically launched. To enable these scenarios, the device may need to negotiate with the network about resources and requirements. Besides, the system may need to know more information about the compute task for routing, execution, and charging, etc.
The current 5G architecture is designed for data communication at the application level without these considerations; therefore, not able to address these computing scenarios with the 6G evolution of the current mobile network. The current offloading model at the edge is based on communication service provider (CSP) infrastructure, where CSP controls policy, charging from the User.
With augmented compute service in 6G network, mobile network operator (MNO) needs to have control over the compute offload policy and charging from the User. Embodiments described
herein enable support of universal integrated circuit card (UICC) based E2E application security with the following objectives:
• Operator Control of the Application Offload Capability.
• Operator Control for Policy and Charging for Compute Offload.
In order to achieve Operator Controlled end-to-end E2E Security for Application offload data between UE and Application Provider/Server, this disclosure proposes solutions in the Trust Domain which contains the following Actors and Entities:
• Operator (MNO): It can be COMPUTE SF in the Application Provider Domain.
• UICC or universal subscriber identity module (USIM) Manufacturer (SIM Based Credential Generation)
• Application Provider (ASP + CSP + MNO or Integrated ASP with MNO)
• ME and Operating System or Application Client
To the best knowledge of the inventors, there are no previous solutions to address Application E2E security with UICC based security anchor points. There are no known methods to dynamically subscribe and add UICC based anchors for application client and application serverside.
To the best knowledge of the inventors, there are no previous solutions to address augmented computing and dynamic workload migration in the cellular network
The following options are proposed in this disclosure, which uses UICC or non UICC based security for establishing the E2E application security.
Trusted third party (Example. Google App Store or Apple App Store or Enterprise App Store) manages the Application Subscription Information.
1. UICC based subscription information and Personalization during the Manufacturing Time o A symmetrical preshared key stored on the SIM/UICC/USIM and encryption/ decry ption service provided by a mobile network operator or Key Management Service provider. o The application vendor has a business relationship with KMS (key management service) provider and provides the key services to the application vendor.
2. Application-level using trusted third-party certificate authority. In this case, Key management server (KMS) provided by a third-party key management service provider is a Certificate Authority. o Symmetrical preshared Key can be pre-provisioned into the application or dynamically provisioned.
Following deployment scenarios are considered for all the options for 6G compute offload cases.
1. Scenario 1: MNO provides connectivity, CSP provides computing infrastructure: Similar to today’s edge computing scenario.
2. Scenario 2: MNO owns communication +compute infrastructure and responsible for communication +compute HW/SW developments
3. Scenario 3: MNO provides communication +compute infrastructure in collaboration with the CSP
MNO collaborates with CSP on comp SW development, e.g., Comp HW/SW is developed by CSP (e.g., CSP as a vendor to MNO).
1. UICC based Application Security Related key material information and Personalization during the Manufacturing Time.
• Figure 6 illustrates an example of this scenario, where all the Applications and Data are secured using public and private key pair that is installed on the UICC during the manufacturing time.
• Scenario 1, 3: MNO has an SLA with CSP who is providing infrastructure as a service. In this case, the Application Session will be secured using public and private key pairs.
• Scenario 2: In this case, Data pipe between UE and Application Offload will be secured using public and private key pair.
In this solution, the trust domain includes a third party providing key management services between MNO and Application Provider.
The provisioning of Group key and UICC identifier from USIM provider to Application provider is done during manufacturing time.
Group Key is used to derive further keys. One option is to use UICC specific, e.g., ICCID; another option is to use Application-specific; the third option is to use per application service provider. Check the KDF in step 4.
Figure 7 illustrates a process flow showing an example of a detailed procedure associated with the relationships in Figure 6:
Application Service Provider has a commercial relationship with MNO, a mobile network operator. Application Service Provider will also establish a business relationship with a Security Key Management service provider.
UE vendor, as part of their manufacturing process, procures a batch of certified eUICC’s from SIM Provider (eUICC manufacturer), with the indication of MNO for the Compute Offload connectivity.
SIM Provider provides a profile for the MNO operator and a Compute Offload security applet. SIM Provider generates a secret key Group Key. It then personalizes each eUICC with a UICC ANCHOR KEYs, where UICC KEY is derived from the Group Key using KDF:
UICC ANCHOR KEY = KDF ( “Application Provider ID or APP ID” || “Group ID” || ICCID || .. , GROUP KEY)
SIM Provider securely sends the GROUP KEY, and the list of ICCIDs sent in the to Application Service Provider.
Application Service Provider shares this information with MNO running a Compute Offload security service, or to a separate Compute Offload security service trusted by Application Service Provider. The Compute Offload security service sets up a Key Management Service.
When a UE is switched on for the first time, it connects to the MNO network.
UE Authenticates with MNO Network.
UE establishes an IP connection to the Application Service Provider’s service platform and initiates a TLS connection
The client sends the following “PSK identity”: “Application ID or ASP ID” || “group-id” || ICCID
KMS validates the identity of the connecting UE and calculates the symmetric key UICC ANCHOR KEY, that is used to complete the TLS handshake with PSK authentication.
The UE is now connected to the service platform and can send application data to the Application Service Provider securely. During the lifetime of the applicable subscription, the KMS, acting on behalf of the Application Service Provider, can refresh the Key.
2. Application-level using trusted third-party certificate authority. In this case, Key management server (KMS) provided by a third-party key management service provider is Certificate Authority.
In this solution, it is proposed that for Application-level Authentication, the Application client uses a certificate installed in the eUICC provided by the UICC Manufacturer. Application Provider uses certificate authority (CA) to sign both Application Client Device and Application Server certificates.
This solution supports dynamic application certification generation.
Pre-condition:
The application provider is provisioned with a server certificate.
UE performs a registration procedure and establishes a compute session, which is associated with a CRB (compute radio bearer).
Figure 8 illustrates an example of a message flow associated with the application-level using trusted third-party certificate authority solution:
1. Application Client on UE requests onboard key generation of a new public/private key pair within the eUICC/UICC security applet. It generates a certificate signing request for the Public Key, and it requests the eUICC/UICC security applet to sign a portion of that request using the private Key. The client application sends the CSR (Certificate Signing Request)to the Application server.
2. The Application server forwards the CSR to their certificate authority. CA signs the client public key using its own Private Key.
3. The CA returns the signed client certificate.
4. Application Server sends the new client certificate, its server certificate, and CA’s selfsigned certificate to the Application Client. The Application client stores these certificates to the UICC/eUICC security applet.
5. The Application Client and Application Server are now able to perform mutual authentication using the application certificates stored in the security applet.
REGISTRATION FOR COMPUTING OFFLOAD SERVICES IN 6G SYSTEMS
Among other things, embodiments of the present disclosure may be directed to resolving the open issue of how to enhance the 5GS for supporting registration for augmented computing and dynamic workload migration, since the current 5GS registration procedure does not support augmented computing and dynamic workload migration. In particular, some embodiments of the present disclosure are directed to enhancements to the 5GS registration procedure to support authorization for Compute offload services.
There are various advantages of providing computing either as a new service or as a network capability based on different scenarios. First, the computing tasks can be completed at the network edge to optimize latency. This latency includes communication latency, as well as the, compute task launch and execution latency. Second, the end device can augment the computing by providing requirements about the computing environment and the computing task. Third, resource efficiency and latency can also be optimized using paradigms like server-less computing to handle more dynamic workload. Embodiments of the present disclosure may help enable the UE to register with the 5GS for services supporting the above computing scenarios.
This disclosure proceeds by providing details for supporting service Authentication and Authorization for Compute offload services. For example, Figure 9 illustrates again (as introduced above for Figure 1) an example of the architecture reference model of the 5G System Architecture which is used as a baseline for the proposed enhancements.
Below are requirements for supporting 5GS Registration for Compute offload services:
• Reuse of the initial Registration procedure with Primary Authentication using SUPI
• New Service subscription for Compute Offload Services
• New USIM Service Indicator for Compute Offload Services
• Support for different tiers of compute offload capabilities
• UE provides generic compute offload capabilities to the network. Network validates requested compute offload capabilities based on subscription data and provides list of supported and allowed compute offload capabilities to the UE.
Note: The detailed definition of compute offload capabilities is not subject to this IDF.
Registration procedure enhancement
Figure 10 illustrates an example of a simplified version of the initial registration procedure (extracted from TS 23.502, v. 16.5.0, 2020-07-09, clause 4.2.2.2.2) with the enhancements for supporting Compute offload services.
1. The UE sends a Registration request and includes the Requested Generic compute offload capability to indicate to the network which Compute offload services it wants to receive.
2. RAN selects an AMF e.g. based on Requested NS SAI, Requested NS SAI may include one or more standardised Slice/Service types (SST) s for Compute offload services.
3. RAN forwards the Registration request to the selected AMF.
4. AMF initiates Primary authentication.
5a-b. The AMF registers the access and retrieves the Subscription data including Compute offload subscription data from the UDM.
6. The AMF creates the UE context including Compute related UE context information.
7. If needed the AMF performs an AM Policy Association
Establishment/Modification.
8. The AMF sends Registration accept. If the UE is subscribed for the Requested
9. The RAN create the UE context including Compute related UE context information.
10. If one or more requested S-NSSAI are subject to Network Slice Specific Authentication and Authorization the AMF initiates NSSAA (network slice specific authentication and authorization).

1. The NF Service Consumer (e.g. AMF) sends a GET request to the resource representing the UE's Compute offload Subscription Data.

SYSTEMS AND IMPLEMENTATIONS
Figures 12-14 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.
Figure 12 illustrates a network 1200 in accordance with various embodiments. The network 1200 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 networks that benefit from the principles described herein, such as future 3GPP systems, or the like.
The network 1200 may include a UE 1202, which may include any mobile or non-mobile computing device designed to communicate with a RAN 1204 via an over-the-air connection. The UE 1202 may be communicatively coupled with the RAN 1204 by a Uu interface. The UE 1202 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electron! c/engine control unit, electron! c/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
In some embodiments, the network 1200 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate
using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
In some embodiments, the UE 1202 may additionally communicate with an AP 1206 via an over-the-air connection. The AP 1206 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 1204. The connection between the UE 1202 and the AP 1206 may be consistent with any IEEE 802.11 protocol, wherein the AP 1206 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 1202, RAN 1204, and AP 1206 may utilize cellular- WLAN aggregation (for example, LWA/LWIP). Cellular- WLAN aggregation may involve the UE 1202 being configured by the RAN 1204 to utilize both cellular radio resources and WLAN resources.
The RAN 1204 may include one or more access nodes, for example, AN 1208. AN 1208 may terminate air-interface protocols for the UE 1202 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 1208 may enable data/voice connectivity between CN 1220 and the UE 1202. In some embodiments, the AN 1208 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, which may be referred to as a CRAN or virtual baseband unit pool. The AN 1208 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 1208 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.
In embodiments in which the RAN 1204 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 1204 is an LTE RAN) or an Xn interface (if the RAN 1204 is a 5G RAN). 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 1204 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 1202 with an air interface for network access. The UE 1202 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 1204. For example, the UE 1202 and RAN 1204 may use carrier aggregation to allow the UE 1202 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc.
The RAN 1204 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 1202 or AN 1208 may be or act as a 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 1204 may be an LTE RAN 1210 with eNBs, for example, eNB 1212. The LTE RAN 1210 may provide an LTE air interface 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 CSI-RS 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 1204 may be an NG-RAN 1214 with gNBs, for example, gNB 1216, or ng-eNBs, for example, ng-eNB 1218. The gNB 1216 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 1216 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 1218 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 1216 and the ng-eNB 1218 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 1214 and a UPF 1248 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN1214 and an AMF 1244 (e.g., N2 interface).
The NG-RAN 1214 may provide a 5G-NR air 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.
In some embodiments, 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 1202 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 1202, 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 1202 with different amount of frequency resources (for example, 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 1202 and in some cases at the gNB 1216. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
The RAN 1204 is communicatively coupled to CN 1220 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 1202). The components of the CN 1220 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 1220 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 1220 may be referred to as a network slice, and a logical instantiation of a portion of the CN 1220 may be referred to as a network sub-slice.
In some embodiments, the CN 1220 may be an LTE CN 1222, which may also be referred to as an EPC. The LTE CN 1222 may include MME 1224, SGW 1226, SGSN 1228, HSS 1230, PGW 1232, and PCRF 1234 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 1222 may be briefly introduced as follows.
The MME 1224 may implement mobility management functions to track a current location of the UE 1202 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.
The SGW 1226 may terminate an SI interface toward the RAN and route data packets
between the RAN and the LTE CN 1222. The SGW 1226 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 1228 may track a location of the UE 1202 and perform security functions and access control. In addition, the SGSN 1228 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 1224; MME selection for handovers; etc. The S3 reference point between the MME 1224 and the SGSN 1228 may enable user and bearer information exchange for inter-3GPP access network mobility in idle/active states.
The HSS 1230 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 1230 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 1230 and the MME 1224 may enable transfer of subscription and authentication data for authenticating/ authorizing user access to the LTE CN 1220.
The PGW 1232 may terminate an SGi interface toward a data network (DN) 1236 that may include an application/content server 1238. The PGW 1232 may route data packets between the LTE CN 1222 and the data network 1236. The PGW 1232 may be coupled with the SGW 1226 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 1232 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 1232 and the data network 12 36 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. The PGW 1232 may be coupled with a PCRF 1234 via a Gx reference point.
The PCRF 1234 is the policy and charging control element of the LTE CN 1222. The PCRF 1234 may be communicatively coupled to the app/content server 1238 to determine appropriate QoS and charging parameters for service flows. The PCRF 1232 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.
In some embodiments, the CN 1220 may be a 5GC 1240. The 5GC 1240 may include an AUSF 1242, AMF 1244, SMF 1246, UPF 1248, NSSF 1250, NEF 1252, NRF 1254, PCF 1256, UDM 1258, and AF 1260 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 1240 may be briefly introduced as follows.
The AUSF 1242 may store data for authentication of UE 1202 and handle authentication- related functionality. The AUSF 1242 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 1240 over
reference points as shown, the AUSF 1242 may exhibit an Nausf service-based interface.
The AMF 1244 may allow other functions of the 5GC 1240 to communicate with the UE 1202 and the RAN 1204 and to subscribe to notifications about mobility events with respect to the UE 1202. The AMF 1244 may be responsible for registration management (for example, for registering UE 1202), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 1244 may provide transport for SM messages between the UE 1202 and the SMF 1246, and act as a transparent proxy for routing SM messages. AMF 1244 may also provide transport for SMS messages between UE 1202 and an SMSF. AMF 1244 may interact with the AUSF 1242 and the UE 1202 to perform various security anchor and context management functions. Furthermore, AMF 1244 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 1204 and the AMF 1244; and the AMF 1244 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 1244 may also support NAS signaling with the UE 1202 over an N3 IWF interface.
The SMF 1246 may be responsible for SM (for example, session establishment, tunnel management between UPF 1248 and AN 1208); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 1248 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 1244 over N2 to AN 1208; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 1202 and the data network 1236.
The UPF 1248 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 1236, and a branching point to support multihomed PDU session. The UPF 1248 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF-to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 1248 may include an uplink classifier to support routing traffic flows to a data network.
The NSSF 1250 may select a set of network slice instances serving the UE 1202. The NSSF 1250 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed.
The NSSF 1250 may also determine the AMF set to be used to serve the UE 1202, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 1254. The selection of a set of network slice instances for the UE 1202 may be triggered by the AMF 1244 with which the UE 1202 is registered by interacting with the NSSF 1250, which may lead to a change of AMF. The NSSF 1250 may interact with the AMF 1244 via an N22 reference point; and may communicate with another NSSF in a visited network via an N31 reference point (not shown).

The UDR may store subscription data and policy data for the UDM 1258 and the PCF 1256,
and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 1202) for the NEF 1252.

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/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 1258 may exhibit the Nudm service-based interface.
The AF 1260 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control.
In some embodiments, the 5GC 1240 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 1202 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 1240 may select a UPF 1248 close to the UE 1202 and execute traffic steering from the UPF 1248 to data network 1236 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 1260. In this way, the AF 1260 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 1260 is considered to be a trusted entity, the network operator may permit AF 1260 to interact directly with relevant NFs. Additionally, the AF 1260 may exhibit an Naf service-based interface.
The data network 1236 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/content server 1238.
