8.0 General p. 75
This clause specifies the delta related to Network Function services description defined in clause 5.2 of TS 23.502. For 5G RG in FWA mode clause 5.2 of TS 23.502 applies.
8.1 UDM Services p. 76
8.1.1 Nudm_SubscriberDataManagement (SDM) Service p. 76
8.1.1.1 General p. 76
In addition to the Subscription data types used in the Nudm_SubscriberDataManagement Service, as defined in Table 5.2.3.3.1-1 of TS 23.502, the additional data types defined in Table 8.1.1.1-1 below are applicable for RGs connected to 5GC via W-5GAN and AUN3 devices.
| Subscription data type | Field | Description |
|---|---|---|
| Access and Mobility Subscription data (data needed for UE Registration and Mobility Management) | RG Level Wireline Access Characteristics | The RG level Wireline Access Characteristics parameter provides QoS information for the W-AGF, as defined in clause 4.5.1.2. This parameter is handled by the UDM as a transparent container. This parameter may also be provisioned in subscriptions for AUN3 devices. |
| AUN3 device connectivity allowed. | Indicates whether the subscriber is allowed to access as an AUN3 device. Only provisioned in subscriptions for AUN3 devices. |
In the case of Wireline access, the Forbidden area information within Table 5.2.3.3.1-1 of TS 23.502 may correspond to a (set of) allowed Global Line ID.

8.3 BSF Services p. 76
8.3.1 General p. 76
The Nbsf_Management_Register /Deregister and Discovery service operations defined in TS 23.502 are extended to allow registration/deregistration and discovery of the binding information when one or multiple /128 IPv6 address or UE IPv6 prefix shorter than /64 is/are assigned to a PDU session.
8.4 PCF Services p. 76
8.4.1 General p. 76
PCF services defined in TS 23.502 apply with modifications described in this clause.
8.4.2 Npcf_SMPolicyControl p. 76
The Npcf_SMPolicyControl_Create and Npcf_SMPolicyControl_Update , defined in TS 23.502, are extended to be able to provide PCF with one or multiple allocated /128 IPv6 UE address or with UE IPv6 prefix shorter than /64.
The Npcf_SMPolicyControl_Update , defined in TS 23.502, is extended to be able to provide PCF with information on a released /128 IPv6 address or on a released UE IPv6 prefix shorter than /64.
8.4.3 Npcf_AMPolicyControl p. 77
8.4.3.1 Npcf_AMPolicyControl_Create service operation p. 77
The input data listed in clause 5.2.5.2.2 of TS 23.502 apply when an AM Policy Association is created for a 5G-RG, except for the handling of RFSP information that applies only if a 5G RG is registered over 3GPP access.
The input information when the UE registers via W-5GAN includes the Access type set to non-3GPP access, the User Location Information including the GLI or the HFC node Id.
The output information when the UE registers via W-5GAN is defined in clause 9.5 and the Policy Control Request triggers applicable for for RG access via W-5GAN are defined in clause 9.5.3.
8.4.3.2 Npcf_AMPolicyControl_Update service operation p. 77
The input data listed in clause 5.2.5.2.5 of TS 23.502 apply when an AM Policy Association is updated for a 5G-RG or for a FN-RG, except for the notification of UE location change (if an RG registers only on Wireline access), PRA changes or RFSP index change.
PCRT on UE location change apply when a 5G RG registers on a second access (5G RG using Hybrid access).
The output information when the UE registers via W-5GAN is defined in clause 9.5 and the Policy Control Request triggers applicable when RG accesses via W-5GAN are defined in clause 9.5.3.
The Access type change trigger requests the AMF to report a new Access Type and RAT Type to the PCF. When the UE simultaneous connects over both 3GPP and wireline non-3GPP access type, the AMF reports the list of Access Type and RAT combinations available in the UE access and mobility context in the Npcf_AMPolicyControl_Update service operation.
