According to some aspects, there is provided the subject matter of the independent claims. Some further aspects are defined in the dependent claims.
The foregoing aspects and other features are explained in the following description, taken in connection with the accompanying drawings, wherein:
The following abbreviations that may be found in the specification and/or the drawing figures are defined as follows:
Turning to
The RAN node 170 in this example is a base station that provides access by wireless devices such as the UE 110 to the wireless network 100. The RAN node 170 may be, for example, a base station for 5G, also called New Radio (NR). In 5G, the RAN node 170 may be a NG-RAN node, which is defined as either a gNB or a ng-eNB. A gNB is a node providing NR user plane and control plane protocol terminations towards the UE, and connected via the NG interface to a 5GC (such as, for example, the network element(s) 190). The ng-eNB is a node providing E-UTRA user plane and control plane protocol terminations towards the UE, and connected via the NG interface to the 5GC. The NG-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and distributed unit(s) (DUs) (gNB-DUs), of which DU 195 is shown. Note that the DU may include or be coupled to and control a radio unit (RU). The gNB-CU is a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. The gNB-CU terminates the F1 interface connected with the gNB-DU. The F1 interface is illustrated as reference 198, although reference 198 also illustrates a link between remote elements of the RAN node 170 and centralized elements of the RAN node 170, such as between the qNB-CU 196 and the gNB-DU 195. The gNB-DU is a logical node hosting RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is partly controlled by gNB-CU. One gNB-CU supports one or multiple cells. One cell is supported by only one gNB-DU. The gNB-DU terminates the F1 interface 198 connected with the gNB-CU. Note that the DU 195 is considered to include the transceiver 160, e.g., as part of a RU, but some examples of this may have the transceiver 160 as part of a separate RU, e.g., under control of and connected to the DU 195. The RAN node 170 may also be an eNB (evolved NodeB) base station, for LTE (long term evolution), or any other suitable base station, access point, access node, or node.
The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N/W I/F(s)) 161, and one or more transceivers 160 interconnected through one or more buses 157. Each of the one or more transceivers 160 includes a receiver, Rx, 162 and a transmitter, Tx, 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor(s) 152, memories 155, and network interfaces 161. Note that the DU 195 may also contain its own memory/memories and processor(s), and/or other hardware, but these are not shown.
The RAN node 170 includes a module 150, comprising one of or both parts 150-1 and/or 150-2, which may be implemented in a number of ways. The module 150 may be implemented in hardware as module 150-1, such as being implemented as part of the one or more processors 152. The module 150-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and is executed by the one or more processors 152. For instance, the one or more memories 155 and the computer program code 153 are configured to, with the one or more processors 152, cause the RAN node 170 to perform one or more of the operations as described herein. Note that the functionality of the module 150 may be distributed, such as being distributed between the DU 195 and the CU 196, or be implemented solely in the DU 195.
The one or more network interfaces 161 communicate over a network such as via the links 176 and 131. Two or more gNBs 170 may communicate using, e.g., link 176. The link 176 may be wired or wireless or both and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.
The one or more buses 157 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optics or other optical communication equipment, wireless channels, and the like. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for gNB implementation for 5G, with the other elements of the RAN node 170 possibly being physically in a different location from the RRH/DU, and the one or more buses 157 could be implemented in part as, for example, fiber optic cable or other suitable network connection to connect the other elements (e.g., a central unit (CU), gNB-CU) of the RAN node 170 to the RRH/DU 195. Reference 198 also indicates those suitable network link(s).
It is noted that description herein indicates that “cells” perform functions, but it should be clear that equipment which forms the cell will perform the functions. The cell makes up part of a base station. That is, there can be multiple cells per base station. For example, there could be three cells for a single carrier frequency and associated bandwidth, each cell covering one-third of a 360 degree area so that the single base station's coverage area covers an approximate oval or circle. Furthermore, each cell can correspond to a single carrier and a base station may use multiple carriers. So if there are three 120 degree cells per carrier and two carriers, then the base station has a total of 6 cells.
The wireless network 100 may include a network element or elements 190 that may include core network functionality, and which provides connectivity via a link or links 181 with a further network, such as a telephone network and/or a data communications network (e.g., the Internet). Such core network functionality for 5G may include access and mobility management function(s) (AMF(s)) and/or user plane functions (UPF(s)) and/or session management function(s) (SMF(s)). Such core network functionality for LTE may include MME (Mobility Management Entity)/SGW (Serving Gateway) functionality. These are merely illustrative functions that may be supported by the network element(s) 190, and note that both 5G and LTE functions might be supported. The RAN node 170 is coupled via a link 131 to a network element 190. The link 131 may be implemented as, e.g., an NG interface for 5G, or an S1 interface for LTE, or other suitable interface for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N/W I/F(s)) 180, interconnected through one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and the computer program code 173 are configured to, with the one or more processors 175, cause the network element 190 to perform one or more operations.
The wireless network 100 may implement network virtualization, which is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external, combining many networks, or parts of networks, into a virtual unit, or internal, providing network-like functionality to software containers on a single system. For example, a network may be deployed in a tele cloud, with virtualized network functions (VNF) running on, for example, data center servers. For example, network core functions and/or radio access network(s) (e.g. CloudRAN, O-RAN, edge cloud) may be virtualized. Note that the virtualized entities that result from the network virtualization are still implemented, at some level, using hardware such as processors 152 or 175 and memories 155 and 171, and also such virtualized entities create technical effects.
It may also be noted that operations of example embodiments of the present disclosure may be carried out by a plurality of cooperating devices (e.g. cRAN).
The computer readable memories 125, 155, and 171 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory. The computer readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multi-core processor architecture, as non-limiting examples. The processors 120, 152, and 175 may be means for performing functions, such as controlling the UE 110, RAN node 170, and other functions as described herein.
In general, the various example embodiments of the user equipment 110 can include, but are not limited to, cellular telephones such as smart phones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, tablets with wireless communication capabilities, as well as portable units or terminals that incorporate combinations of such functions.
Having thus introduced one suitable but non-limiting technical context for the practice of the example embodiments of the present disclosure, example embodiments will now be described with greater specificity.
Features as described herein may generally relate to policy and charging control (PCC) rules.
For 5GC, when the policy charging function (PCF) determines that new PCC rules are required for a protocol data unit (PDU) session, for example due to an application function (AF) request, it shall provide them to the session management function (SMF) using the Npcf_SMPolicyControl_UpdateNotify service operation. When the same new PCC rules shall apply for multiple UEs (or multiple PDU sessions of the same UE), the PCF needs to invoke Npcf_SMPolicyControl_UpdateNotify once session per management (SM) policy association, for example once per UE/PDU Session. When the required quality of service (QOS) or QoS monitoring changes for multiple UE IP addresses, the AF and/or network exposure function (NEF) needs to invoke Npcf_PolicyAuthorization_Update request once per UE IP address.
PCC is documented by 3GPP for 5GC in TS 23.503 (stage 2) and (among other specifications) TS 29.512, TS 29.513, TS 29.514 and TS 29.551 (stage 3). A PCC rule is a set of information enabling the detection of a service data flow and providing parameters for policy control and/or charging control and/or other control or support information. The possible information is described in clause 6.3.1 of TS 23.503.
For the evolved packet system (EPS), when the policy and charging rules function (PCRF) determines that new PCC rules are required for a packet data network (PDN) connection, for example due to an AF request, it shall provide them to the packet data network gateway (PGW) and/or policy control enforcement function (PCEF) using a diameter random access response (RAR) message. When the same new PCC rules shall apply for multiple UEs (or multiple PDN connections of the same UE), the PCRF needs to invoke the diameter RAR message once per SM policy association, for example once per UE/PDN connection.
PCC is documented by 3GPP for EPS in TS 23.203 (stage 2) and TS 29.212, TS 29.213, TS 29.214, TS 29.250 and TS 29.251 (stage 3).
A PCC rule contains a description of traffic flows it relates to (e.g. IP source and destination addresses and UDP/TCP source destination port numbers) that may also take the form of an application identifier. The related traffic flow description for the application identifier is then provided from the AF towards the NEF (e.g. packet flow description function (PFDF)) and then towards the SMF as a packet flow description (PFD) without involvement of the PCF. See clause 4.18 of TS 23.502.
Invoking Npcf_SMPolicyControl_UpdateNotify once per SM policy association, for example once per UE/PDU session, may lead to excessive signaling if many UEs/PDU sessions require the same PCC rule update(s) (e.g. updates indicated within the same AF request are applicable to multiple/group of UEs). For example, if the AF request that triggered this update of PCC rules targeted a group identifier corresponding to a group of 1000 UEs, then 1000 separate HTTP messages between the PCF and the SMF will have to be sent. The same excessive signaling problem is applicable for NEF to PCF, in case Nnef_AFsessionWithQoS service with multiple UEs leads to multiple invocations of Npcf_PolicyAuthorization per UE/PDU session.
In an example embodiment, signaling of PCC rules that apply to multiple UEs/PDU sessions may be handled by the same SMF in one single message towards that SMF. The applicability of the PCC rule to multiple policy control session or PDU sessions/UEs may be indicated as part of the PCC rule (i.e. within the PCC rule itself). The applicability of the PCC rule to multiple policy control sessions may be indicated either via a correlation ID that is assigned by the PCF to each related policy control session, or by direction indication of applicable PDU sessions/UEs or policy control session IDs. Optionally, one of the existing policy control sessions may be used to provide such PCC rules. Alternatively, a (dedicated) non-PDU session related policy control session may be used to provide such PCC rules.
Referring now to
In an example, the PCF may provide a mapping of correlation IDs to PDU sessions. For example, the PCF may indicate, to the SMF, that correlation ID 1 is assigned to PDU sessions A, B, C; and correlation ID 2 is assigned to PDU sessions D, E, F. This example is not limiting; a single correlation ID may map to any number of PDU sessions.
The “Correlation Id(s)” may be assigned to be the same for, for example, all the PDU sessions with the same data network name (DNN) and/or single network slice selection assistance information (S-NSSAI) and/or other characteristics (e.g. access type, attributes of the SM policy context provided by the SMF, etc.). Additionally or alternatively, the “Correlation Id(s)” may be assigned to be the same, for example, for all the PDU sessions of UEs identified by a group ID. Additionally or alternatively, the “Correlation Id(s)” may be assigned to be the same for any combination of PDU sessions for which the PCF expects to need “batch” updates, for example based on implementation.
There are various possibilities for implementation-specific “grouping” of the PDU sessions. The PCF may, for example, be configured with information that indicates which AF is responsible for a PDU session. This may be, for example, based on DNN/S-NSSAI, target UE groups, or their combination. For example, the PCF may know that UE groups A, B, and C in slices S1 and S2 are all managed by a same AF, and therefore that AF is likely to send requests for them, so the PCF may assign the same correlation ID to all of those UE groups.
Another example is IP address ranges. The PCF may be configured to know that IPs belonging to a specific address range are given by the SMF to, for example, V2X applications, which may be expected to have similar requirements/requests later, so the PCF may assign the same correlation ID to all PDU sessions that have an IP in that range.
At 230, due to internal PCF logic or due to an external AF request that targets a group of UEs (e.g. Nnef_TrafficInfluence or Nnef_AfSessionWithQoS, see 3GPP TS 29.522), the PCF may be required to install new/updated PCC rules (with the same contents) for multiple PDU sessions (i.e. multiple SM policy associations), or to deinstall/uninstall such PCC rules. In other words, the PCF may detect a trigger, or may determine, to send the same PCC/session rule to many PDU sessions. An example of such a trigger may be an AF request as applied to UEs connected to the same DNN/S-NSSAI or same external group.
An example of internal PCF logic may be based on periodic checking of statistics of network usage and performance (either locally or by contacting the network data analytics function (NWDAF)) and a determination that the PCF should stop authorizing too demanding QoS for PDU sessions of a certain type, or towards certain external networks.
At 240, the PCF may identify the SM policy associations that need to be updated due to the above, and may derive their correlation identifier(s), and may group them based on the SMF that handles them. At 250, the PCF may invoke Npcf_SMPolicyControl_UpdateNotify only once per handling SMF (e.g. each SMF for which at least one correlation ID has been created and for which an update has been triggered) by, for example, including the Correlation Id(s) which indicate that the update is applicable to all the PDU sessions with the given Correlation Id(s). For example, the PCF may transmit, to the SMF, a Npcf_SMPolicyControl_UpdateNotify request, which may include the Correlation ID and updated PCC/session rule. Optionally, the PCF may include an “exception list” that includes the PDU session ID, which was assigned the same “Correlation Id” but may not be applicable (i.e. excluded) for the UpdateNotify request in some rare cases, for example based on an AF request. In other words, the PCF may indicate a PDU session that is associated with a correlation ID, but to which new or updated PCC rules do not apply.
At 260, the SMF may respond to the UpdateNotify request, but may also indicate if there is some failure at one or more of the PDU sessions in applying the requested update. For example, the SMF may transmit, the PCF, a to Npcf_SMPolicyControl_UpdateNotify response, which may include additional PDU session IDs that failed, for example because they are no longer handled by this SMF. Failure may mean that the update of a PDU session was not successful and/or was not performed. At 270, the PCF may attempt to update individually those SM policy associations for which the update failed by sending an UpdateNotify to each of them (e.g. using existing mechanisms).
In an example embodiment, explicit indication of additional impacted SM policy associations may be provided. For example, instead of using Correlation Ids in steps 2 (220), 4 (240), and 5 (250), the PCF may explicitly indicate in step 5 (250) the entire list of impacted PDU sessions (e.g. by including in the UpdateNotify an array of impacted PDU Session Ids). A technical effect of using correlation identifiers may be to avoid having to send an array of, for example, 1000 PDU session Ids. However, using a list of impacted PDU sessions may have the technical effect of being more straightforward and not needing prior creation of correlation IDs nor extensions of the SMPolicyControl_Create/Update response.

At 325, the SMF may detect at the network repository function (NRF) PCF(s) serving DNN/NSSAI that the SMF also serves. For each such PCF, the SMF may create an SM shared policy association (i.e. in the PCF) and provide its own SMF ID and a URL where to receive updates in the request. For example, the SMF may transmit, to the PCF, a Npcf_SMSharedPolicyControl_Create request. Both the SMF and the PCF may be aware of the SM shared policy association and where it is stored. At 330, the PCF may accept the creation of a SM shared policy association (e.g. with respect to 305, 315, or both). It may provide shared PCC rule(s) and then indicate for each shared PCC rule the PDU session(s) and UE ID(s) to which it applies. The PCF may only indicate PDU session(s) and UE ID(s) for which it has established policy associations with the SMF. For example, the PCF may transmit, to the SMF, a Npcf_SMSharedPolicyControl_Create response. At 335, due to internal PCF logic or due to an external AF request that targets a group of UEs (e.g. Nnef_TrafficInfluence or Nnef_AfSessionWithQoS, see 3GPP TS 29.522), the PCF may be required to install new/updated PCC rules (with the same contents) for multiple PDU sessions (i.e. multiple SM policy associations), or to deinstall/uninstall such PCC rules. In other words, the PCF may detect a trigger to send the same PCC/session rule to many PDU sessions. An example of such a trigger may be an AF request as applied to UEs connected to the same DNN/S-NSSAI or same external group. At 340, the PCF may derive and relate shared PCC rules and may identify the SM policy associations and/or PDU sessions and UE IDs for which the shared PCC rule applies (i.e. SM shared policy associations). The PCF may identify the affected SMFs and related shared SM policy associations based on the SMF ID associated with SM policy associations. The PCF may invoke Npcf_SMSharedPolicyControl_UpdateNotify only once per handling SMF (e.g. each SMF for which at least one correlation ID has been created and for which an update has been triggered), and may provide instructions to install, update, or deinstall/uninstall shared PCC rule(s) and indicate, for each installed shared PCC rule, the PDU session(s) and UE ID(s) to which it applies. The PCF may update the shared PCC rules with updated information about applicable PDU sessions and UE IDs, for example PDU sessions and UE IDs to be added and/or to be removed.
At 345, the PCF may transmit, to the SMF, a Npcf_SMSharedPolicyControl_UpdateNotify request. At 350, the SMF may respond to the UpdateNotify request, and optionally indicate PDU session IDs and/or UE IDs for which the PCC rule operation succeeded and/or for which the PCC rule operation failed. For example, the SMF may to PCF, a transmit, the Npcf_SMSharedPolicyControl_UpdateNotify response. At 355, the PCF may attempt to update individually those SM policy associations for which the update failed by sending an UpdateNotify message to each of them (e.g. using existing mechanisms).
In another example embodiment, the PCC rules may contain a reference to a data structure that may be available at the SMF and that may be applicable to PCC rules in many SM policy associations. The reference to the data structure may comprise, for example, a policy fragment identifier. For example, the SMF may have a list of reference/structure pairs (e.g. ref1: QoS1, TrafficSteeringX, ref2: QoS1, TrafficSteeringX, etc.). The PCC rule may contain only the reference. In order to change the QoS of a PCC rule, the PCF may not change the PCC rule at all, but change/update only the data structure that corresponds to, for example, ref1. For example, a fragment of policy or charging information mapped to a policy fragment identifier may be updated within the data structure.
Update of the structure may be independent of the SM policy association, and may indirectly update all PCC rules that reference it (e.g. automatically). Optionally, implicit PCC rule updates may be based on references, where the data structure (with traffic control reference) may be stored in the unified data repository (UDR), and the SMF may fetch the structure from there and/or subscribe to updates (e.g. with respect to part of the structure). Storage in other (network) entities may be possible. Additionally or alternatively, PFDs (e.g. within the UDR) may be extended with additional contents, for example to control the QoS of packet flows. Additionally or alternatively, a non-PDU session related policy control session may be used to provide such data structures from PCF to SMF.
In an example embodiment, for parts of the PCC rule that are frequently AF-influenced (e.g. QoSData and TrafficControlData), a reference may be included in the PCC rule, instead of the detailed values (this option currently does not exist in the PCC rule, see 3GPP TS 29.512). TABLE 1 illustrates a small extract of the example PCC rule definition of 29.512, which may be extended to include gosRef and tcRef. TABLE 1 may comprise an example of implicit PCC rule updates based on references.
Both tcRef and TrafficControlData may be available at the SMF as a pair.
In an example embodiment, new application data may be defined in the UDR and respective northbound interfaces (NBIs) in the NEF, for example in order to allow the AF to change the values that correspond to such references, and allow the SMF to retrieve and subscribe to such data. Referring now to
The AF (or the PCF itself) may then update multiple UEs/sessions without any N7 interactions (i.e. without any PCF-SMF signaling). Referring now to
At 505, the SMF may transmit, to the UDR, Nudr_DM_Subscribe. At 510, the AF may transmit, to the NEF, Nnef_TcDataManagement_Create. The AF may not be aware of any PCC rules; it may be configured to provide updates to data using a reference. At 515, the NEF may transmit, to the UDR, Nudr_DM_Create. At 520, the PCF may check and/or update the data in the UDR. At 525, the UDR may transmit, to the SMF, Nudr_DM_Notify. One or more PCC rules may be installed on the SMF by the PCF. The SMF may receive notifications regarding data stored at the UDR that is referenced in PCC rules.
In an example embodiment, tcRef may be used as an input to the TrafficInfluence_Create request, for example in order to provision the initial PCC rules that contain the reference. In an example embodiment, only tcRef may be added to the possible inputs of TrafficInfluence_Create in step 6 (530) and to the PCC rules of step 7 (535), but the rest of these steps may be done/performed using existing mechanisms.
At 530, the AF may transmit, to the NEF, Nnef_TrafficInfluence_Create. At 535, the PCC control may comprise a PCC rule containing “tcRef1” instead of detailed inputs for traffic steering control.
In an example embodiment, in order to (implicitly) update the PCC rules, the AF (or the PCF) may simply update (and the PCF may also authorize, as during the creation) in the UDR the traffic control data that corresponds with a given reference. The SMF may be notified about this update, which may mean that no explicit update of the SM policy association may be required (thus avoiding the need for sending e.g. 1000 HTTP requests from the PCF to the SMF).
At 540, the AF may transmit, to the NEF, Nnef_TcDataManagement_Update. At 545, the NEF may transmit, to the UDR, Nudr_DM_Update. At 550, the PCF may check and/or update the data in the UDR. At 555, the UDR may transmit, to the SMF, Nudr_DM_Notify.
In an example embodiment, the provisioning of PFDs may be as defined in TS 23.502, and they may be referenced in the PCC rule via the application ID. The PFD defined in TS 23.503 may include the following information: PFD id; and one or more of the following: 3-tuple(s) including protocol, server side IP address and port number; the significant parts of the URL to be matched, e.g. host name; and/or a domain name matching criteria and information about applicable protocol(s). It may be noted that, based on the agreement between AF and mobile operator, the PFD may be designed to convey proprietary extension(s) for proprietary application traffic detection mechanism(s). It may be noted that how the PFD(s) are used in service flow detection may be specified in clause 6.2.2.2. The PFD defined in TS 23.503 may optionally be extended to include one or more of the following (with the same meaning as defined within PCC rules): 5QI; ARP; gate status; data network access identifier; and/or Per DNAI: N6 traffic routing information.
In an example embodiment, if the same information is provided both in a PCC rule containing the application ID, and in the PFD, the information in the PCC rule may prevail. In an alternative example embodiment, if the same information is provided both in a PCC rule containing the application ID, and in the PFD, the information in the PFD may prevail.
Referring now to
In an example embodiment, the shared structure may, for example, contain the information indicated in TABLE 2:
At 615, 625, for each PDU session, the SMF may create an SM policy association with the PCF, for example as described in 3GPP TS 29.513 clause 5.2. The SMF may provide the PDU session ID and UE ID and its own SMF ID in the request. For example, the SMF may transmit, to the PCF, a Npcf_SMPolicyControl_Create request. At 620, 630, for each PDU session, the PCF may accept the creation of a SM policy association. In the example of
At 635, due to internal PCF logic or due to an external AF request that targets a group of UEs (e.g. Nnef_TrafficInfluence or Nnef_AfSessionWithQOS, see 3GPP TS 29.522), the PCF may be required to update PCC rules (with the same contents) for multiple PDU sessions (i.e. multiple SM policy associations). For example, the PCF may detect a trigger to send the same PCC/session rule to many PDU sessions, for example an AF request as applied to UEs connected to a same DNN/S-NSSAI or a same external group. At 640, the PCF may derive related shared structure(s) and the updated contents for those shared structures, and may identify the SM shared policy associations where those shared structures are installed. It may also decide to create new shared structures and install them in all SM shared policy associations. At 645, the PCF may invoke Npcf_SMSharedPolicyControl_UpdateNotify only once per handling SMF and may provide instructions to install, update, or deinstall/uninstall shared structures. If the PCF installs new shared structures, it may also update SM policy associations with PCC rules that reference the new shared structure. If the PCF deinstalls/uninstalls shared structures, it may previously update SM policy associations with PCC rules that reference the shared structure to remove those references. At 650, the SMF may respond to the UpdateNotify request and handle the traffic matching all PCC rules that reference the shared structure according to the updated shared structure instructions. For example, the SMF may transmit, to the PCF, a Npcf_SMSharedPolicyControl_UpdateNotify response.

Therefore, the PCF may be replaced by PCRF, and the SMF may be replaced by PGW/PCEF. Diameter messages may apply instead of the service operations indicated in the call flows.
