The anchor SMF triggers a request to NSACF for maximum number of PDU sessions per network slice control during PDU session establishment/release procedures in clauses 4.3.2 and 4.3.4 of TS 23.502 [3]. During PDN connection establishment in EPC, the SMF+PGW-C selects an S-NSSAI associated with the PDN connection as described in clause 5.15.7.1. When authorization is revoked for an S-NSSAI that is in the current Allowed NSSAI for an Access Type, the AMF shall provide a new Allowed NSSAI to the UE and trigger the release of all PDU sessions associated . The NSSF determines and returns the appropriate NRF to be used to NOTE 2: The PCF for the PDU Session may in addition be configured to monitor the data rate per Network Slice for a UE and to strengthen or relax the traffic restrictions for individual PDU Sessions or PCC rules accordingly, as described in TS 23.503 [45] clause 6.2.1.9. The UE shall include a Requested NSSAI (as described in clause 5.15.5.2.1) with the associated mapping of Requested NSSAI in the Registration Request message. We can either use or remove this, but make sure that the same setting are done in both "amf.yaml" and "open5gs-gnb.yaml" configure files above. 3GPP Access and/or N3GPP Access). When EPS counting is performed for a network slice, and the UE with ongoing PDN connection(s) moves from EPC to 5GC, session continuity is guaranteed from NSAC standpoint, as the admission was granted at the time of PDN connection establishment, i.e. Found inside – Page 81gNB AMF1 AMF2 NG SETUP REQUEST S-NSSAI list supported by TA NG SETUP RESPONSE ...

The Subscription Information may contain restrictions to the simultaneous registration of network slices. The default S-NSSAIs, if more than one is present, are associated with the same NSSRGs, i.e. The Unsubscribe operation is used by an NF Service Consumer (such Architecture principles U-plane function (User Plane Function, UPF) is separated from the C-Plane function group • Terminal-related management is performed at one location and the traffic is handled on multiple slices • These functions are reallocated in AMF and SMF: MM can be performed in a centralized manner and session management can . A UE subscription information may include an optional Slice Maximum Bit Rate for the UE (Subscribed UE-Slice-MBR) for an S-NSSAI, which applies for 3GPP access type only. determines the mapping of the configured NSSAI for the serving PLMN and In addition, the network may provide the Configured NSSAI for the Serving PLMN, the associated mapping information, and the rejected S-NSSAIs. Then it will work. – It determines the target AMF Set to be used to serve the UE, or, based on configuration, the list of candidate AMF(s), possibly after querying the NRF. Mobility between 5GC to EPC does not guarantee all active PDU Session(s) can be transferred to the EPC. Furthermore, in some cases, storage of parameters is also offloaded to mobile phones like default configured NSSAI and mobile phone's copy of operator controlled PLMN selector with access technology. In addition to sending the new Allowed NSSAI to the UE, when a Network Slice used for a one or multiple PDU Sessions is no longer available for a UE, the following applies: – If the Network Slice becomes no longer available under the same AMF (e.g. When the AMF belongs to multiple Network Slice instances, based on configuration, the AMF may use an NRF at the appropriate level for the SMF selection. Requested NSSAI: NSSAI provided by the UEto the Serving PLMN duringregistration. If the V-SMF need be reallocated, i.e. AMF uses this feature to update the NSSF with the S-NSSAIs that Slice suitable for the handling of V2X services. NOTE 3: The configuration in the AMF depends on the operator’s policy. AMF queries the NSSF with this specific S-NSSAI, the NF type of the NF During PDN connection establishment in the EPC, the UE allocates the PDU Session ID and sends it to the SMF+PGW-C via PCO. The UE shall not include in the Requested NSSAI any S-NSSAI that is currently rejected by the network (i.e. S-NSSAI value 2. NOTE 2: The details and more cases of S-NSSAI rejection are described in TS 24.501 [47]. delete the NSSAI availability information stored for the NF service consumer in OpenNESS provides ansible scripts for setting up NGC components for two scenarios. NG-RAN and 5G-NR describes the deployment of 5G NSA (non standalone 5G) and 5G-SA (standalone 5G). Sessions will start using the newer values. Delete: The Delete service operation is used by the AMF to Each NSACF is configured with the maximum number of UEs per network slice and the maximum number of PDU Sessions per network slice which are allowed to be served by each network slice that is subject to NSAC. AMF Region: An AMF Region consists of one or multiple AMFSets Allowed NSSAI: NSSAI provided by the Serving PLMN during e.g. different S-NSSAIs with the same Slice/Service Type but different Slice Differentiators (see clause 5.15.2.1).

The Allowed NSSAI is then composed of the list of S-NSSAI(s) in the Requested NSSAI permitted based on the Subscribed S-NSSAIs and/or the list of S-NSSAI(s) for the Serving PLMN which are mapped to the HPLMN S-NSSAI(s) provided in the mapping of Requested NSSAI permitted based on the Subscribed S-NSSAIs, or, if neither Requested NSSAI nor the mapping of Requested NSSAI was provided or none of the S-NSSAIs in the Requested NSSAI are permitted, all the S-NSSAI(s) marked as default in the Subscribed S-NSSAIs and taking also into account the availability of the Network Slice instances as described in clause 5.15.8 that are able to serve the S-NSSAI(s) in the Allowed NSSAI in the current UE’s Tracking Areas in addition to any Network Slice instance restriction for the S-NSSAI(s) in the Allowed NSSAI provided by the NSSF. An S-NSSAI can have standard values (i.e. an RRC connection Establishment defined in TS 38.331 [28]) according to one of these modes: a) The UE shall include an NSSAI set to the Allowed NSSAI, if available, in the Access Stratum Connection Establishment caused by a Service Request, Periodic Registration Update or Registration procedure used to update the UE capabilities; b) The UE shall include a NSSAI with the following content: – for the case of Access Stratum Connection Establishment caused by a Service Request: an NSSAI including the S-NSSAI(s) of the Network Slice(s) that trigger the Access Stratum Connection Establishment; i.e. – If AMF has not subscribed to Network Slice instance restriction service from NSSF and NSSF has subscribed to slice load level and/or Observed Service Experience and/or Dispersion Analytics related network data analytics for a Network Slice from NWDAF, NSSF may use the analytics information for the determination of the (Network Slice instance(s) and the) list of S-NSSAI(s) in the Allowed NSSAI(s) to serve the UE. NOTE 1: The value(s) used in the Default Configured NSSAI are expected to be commonly decided by all roaming partners, e.g. The Subscription Information shall contain one or more S-NSSAIs i.e. If the Requested NSSAI includes S-NSSAIs which map to S-NSSAIs of the HPLMN subject to Network Slice-Specific Authentication and Authorization, the AMF shall include in the Registration Accept message an Allowed NSSAI containing only those S-NSSAIs that are not to be subject to Network Slice-Specific Authentication and Authorization and, based on the UE Context in AMF, those S-NSSAIs for which Network Slice-Specific Authentication and Authorization for at least one of the corresponding HPLMN S-NSSAIs succeeded previously regardless the Access Type, if any. One or more S-NSSAIs in an Allowed NSSAI provided to the UE can have values which are not part of the UE’s current Network Slice configuration information for the Serving PLMN. It has been motivated by various factors, some are purely related to communications, such as serving highly populated areas with high-speed mobile access, and some are less related to communications, such as battery lifetime for over 10 years, among others. the UE may request to register these S-NSSAIs again next time the UE sends a Requested NSSAI. The HPLMN only sends S-NSSAIs sharing all the NSSRGs of the Default S-NSSAIs to a non-supporting VPLMN as part of the subscription information, i.e. Subscribe: The Subscribe operation is used by the AMF to Tracking Areas are able to serve a given S-NSSAI, based on for SM it would be the S-NSSAI of the PDU Session the SM message is about; – for the case of Access Stratum Connection Establishment caused by a Periodic Registration Update or Registration procedure used to update the UE capabilities, an NSSAI set to the Allowed NSSAI; c) The UE shall not include any NSSAI in the Access Stratum Connection Establishment caused by Service Request, Periodic Registration Update or Registration procedure used to update the UE capabilities; or. Ce dernier (allowed NSSAI) a été récupéré lors d'un précédent enregistrement. A PDU Session is associated to an S-NSSAI and a DNN. The Handover procedure is executed as documented in TS 23.502 [3]. A PDU Session is associated to an S-NSSAI and a DNN. The allowed NSSAI is configured of an S-NSSAI list available to the UE 101. the UE, the NSSF does the following: It selects the Network Slice instance(s) to serve The PDU Session Establishment in a Network Slice instance to a DN allows data transmission in a Network Slice instance. 61. In such cases, procedures mentioned in clause 5.15.5.2.2 or clause 5.15.5.2.3 apply. The mapping of S-NSSAIs of the Requested NSSAI to HPLMN S-NSSAIs may also be provided (see clause 5.15.4.1.2 for when this is needed). NOTE 5: The S-NSSAIs in the Allowed NSSAI for Non-3GPP access are available homogeneously in the PLMN for the N3IWF case. Network routing can be broadly categorized into Internet routing, PSTN routing, and telecommunication transport network routing. This book systematically considers these routing paradigms, as well as their interoperability. In addition to the interworking principles documented in clause 5.17.2 the following applies for interworking with N26: – When UE moves from 5GS to EPS, the UE context information sent by AMF to MME includes the UE Usage type, which is retrieved from UDM by AMF as part of subscription data. The UE may support remote provisioning of credentials for NSSAA, specified in clause 5.39. marked as default S-NSSAI), mapping to the Configured NSSAI for the HPLMN, PLMN ID of the Subscription Permanent Identifier NOTE: The details of how the RAN uses NSSAI information are described in TS 38.300 [27]. This book provides a clear, concise, complete and authoritative introduction to System Architecture Evolution (SAE) standardization work and its main outcome: the Evolved Packet Core (EPC), including potential services and operational ... The NSACF maintains a list of UE IDs based on the requests from SMF+PGW-C(s) and AMF, and adjusts the current number of registrations accordingly. – If the UE only uses standard S-NSSAI values, then the same S-NSSAI values can be used in VPLMN as in the HPLMN. – The Allowed NSSAI received in a Registration Accept message or a UE Configuration Update Command applies to a PLMN when at least a TAI of this PLMN is included in the RA/TAI list included in this Registration Accept message or UE Configuration Update Command. Objectives - Bring papers on new developments, innovations and standards to the readers - Cover pre-development, including technologies with potential of becoming a standard, as well as developed / deployed standards - Publish on-going work ... The NSACF stores UE ID with the associated one or more Access Type(s), i.e. by the use of values standardized by 3GPP or other bodies. – Depending on the available information and based on configuration, the AMF may query the appropriate NRF (e.g. When the serving PLMN AMF provides the Configured NSSAI to the UE, and the UE has indicated it supports the subscription-based restrictions to simultaneous registration of network slices feature, the AMF also provides the UE with the NSSRG information related to the S-NSSAIs of the HPLMN which are in the mapping information of the Configured NSSAI.

The S- NSSAI(s) are included in the subscription information. where U max,s,n is the maximum allowed number of users of the s -th service of the n -th tenant, which is established for hardware limitation purposes (p rocessor, memory, power). The UE shall not include in the Requested NSSAI any of the S-NSSAIs from the Pending NSSAI the UE stores, regardless of the Access Type. Core network is one of the main and important architectural component of mobile network systems. NOTE 1: Number of simultaneous connection of Network Slice instances per UE is limited by the number of S-NSSAIs in the Requested/Allowed NSSAI as described in clause 5.15.2.1. When a UE registers with a PLMN, if for this PLMN the UE has not included a Requested NSSAI nor a GUAMI while establishing the connection to the (R)AN, the (R)AN shall route all NAS signalling from/to this UE to/from a default AMF. There is at most one Configured NSSAI per PLMN. Network slicing support for roaming is described in clause 5.15.6. if the UE has no Configured NSSAI nor an Allowed NSSAI for the serving PLMN; – the Configured-NSSAI, or a subset thereof as described below, e.g. ALLOWED NSSAI to the Subscribed S-NSSAI(s). Allowed NSSAI: Huawei, OPPO: imported from 3GU: R3‑181899: Correction to attribute of S-NSSAI: Huawei: imported from 3GU: R3‑181900 (TP for NR BL CR for TS 38.300): Correction to attribute of S-NSSAI: Huawei: imported from 3GU: R3‑181901: Correction to attribute of S-NSSAI: Huawei: imported from 3GU: R3‑181902 finds a match. Allowed. Network slicing is a key enabler for providing new services to industry verticals. input parameters. NOTE: I-SMF does not interact with NSCAF. S-NSSAI admission control can be run only for those procedures for which Initial context setup procedures is used, i.e. NOTE 1: The support of all standardised SST values is not required in a PLMN. If the UE Configuration Update Command contains an Allowed NSSAI but not a TAI List, then the last received RA/TAI list applies for the decision on which PLMN(s) the Allowed NSSAI is applicable. The NSSAA status of each S-NSSAI, if any is stored, is transferred when the AMF changes. The subscription information the UDM sends to the AMF shall include at least one default S-NSSAI. – all the S-NSSAI(s) in the Requested NSSAI are still to be subject to Network Slice-Specific Authentication and Authorization; or. Based on operator configuration, the NSSF may The availability of a Network Slice refers to the support of the S-NSSAI in the involved NFs. Oracle NSSF interaction with NRF allows retrieving specific NF services When a PDU Session for a given S-NSSAI is established using a specific Network Slice instance, the CN provides to the (R)AN the S-NSSAI corresponding to this Network Slice instance to enable the RAN to perform access specific functions. In a PLMN, when an S-NSSAI is associated with more than one Network Slice instance, one of these Network Slice instances, as a result of the Network Slice instance selection procedure defined in clause 5.15.5, serves a UE that is allowed to use this S-NSSAI. If the redirection message is sent by the AMF via the 5G-AN, the message shall include information for selection of a new AMF to serve the UE. increase or decrease) the current number of PDU Sessions per network slice so that it does not exceed the maximum number of PDU session allowed to be served by that network slice. – If received, an S-NSSAI rejected for the current Registration Area shall be stored in the UE while RM-REGISTERED until the UE moves out of the current Registration Area or until the S-NSSAI is deleted. The Network Slice configuration information contains one or more Configured NSSAI(s). A UE for which the Configured NSSAI for the Serving PLMN has been updated as described in clause 5.15.4.1 and has been requested to perform a Registration procedure, shall initiate a Registration procedure to receive a new valid Allowed NSSAI (see clause 5.15.5.2.2). If an AMF change is required, this shall be triggered by the AMF using the UE Configuration Update procedure indicating a UE re-registration is required. The NSACF performs the following for checking network slice availability prior to returning a response to the SMF+PGW-C: – For NSAC for number of UEs, if the UE identity is already included in the list of UE IDs registered with a network slice, or the UE identity is not included in the list of UE IDs registered with a network slice and the current number of UE registration did not reach the maximum number, the NSACF responds to the SMF+PGW-C with the information that the network slice is available. The UE default mode of operation is the following: – For 3GPP access the UE shall by default operate in mode d) unless it has been provided with an indication to operate in mode a), b) or c). – When a PDU Session is established, the CN provides to the AN the S-NSSAI with the value from the VPLMN corresponding to this PDU Session, as described in clause 5.15.5.3. NOTE: For example, if the NSACF is configured to apply NSAC for 3GPP Access Type only, the NSACF counts registration via 3GPP access type only. NOTE 6: How the UE selects the subset of configured NSSAI or allowed NSSAI to be provided in the requested NSSAI is implementation specific. This book - a new edition of SAE and the Evolved Packet Core - provides clear, concise and comprehensive coverage of the entire SAE/ EPC architecture, explaining concepts and standards and how they are used in commercial service settings. Found inside – Page 93o SD (Slice Differentiator) to differ slices of the same SST; • NSSAI ... an idea of replacing pre-configured physical network elements with general-purpose ... In this case the AMF provides the UE with a Configured NSSAI including all the S-NSSAIs in the subscription information the AMF receives. The Default Configured NSSAI, if it is configured in the UE, is used by the UE in a Serving PLMN only if the UE has no Configured NSSAI for the Serving PLMN. Otherwise, the NSACF returns the response indicating that the maximum number with the network slice has been reached. More precisely, an application will be associated with a SM-NSSAI (as mentioned above, this includes a slice service type and may also include a service differentiator), and data for this application will be routed to a PDU session associated to this SM-NSSAI. The S-NSSAI(s) in the PDU Session Establishment contain one Serving PLMN S-NSSAI value and in addition may contain a corresponding HPLMN S-NSSAI value to which this first value is mapped (see clause 5.15.5.3). – When the UE context in the AMF does not yet include an Allowed NSSAI for the corresponding Access Type, the AMF queries the NSSF (see (B) below for subsequent handling), except in the case when, based on configuration in this AMF, the AMF is allowed to determine whether it can serve the UE (see (A) below for subsequent handling). functions. Allowed. (B) When required as described above, the AMF needs to query the NSSF, and the following is performed: – The AMF queries the NSSF, with Requested NSSAI (excluding S-NSSAIs subject to NSSAA which are in "Pending" state and are not yet in the Allowed NSSAI, if any), Default Configured NSSAI Indication, mapping of Requested NSSAI to HPLMN S-NSSAIs, the Subscribed S-NSSAIs (with an indication if marked as default S-NSSAI), NSSRG Information (if provided by the UDM, see clause 5.15.12), any Allowed NSSAI it might have for the other Access Type (including its mapping to HPLMN S-NSSAIs), PLMN ID of the SUPI and UE’s current Tracking Area.
