6 Control and User Plane Protocol Stacks p. 34

6.1 General p. 34

This clause specifies the protocol stacks between 5G-RG, FN-RG and 5GS entities for supporting W-5GAN.

6.2 Control Plane Protocol Stacks for W-5GAN p. 34

6.2.1 Control Plane Protocol Stacks between the 5G-RG and the 5GC p. 34

Reproduction of 3GPP TS 23.316, Fig. 6.2.1-1: Control Plane stack for W-5GAN for 5G-RG

Figure 6.2.1-1: Control Plane stack for W-5GAN for 5G-RG

The control plane protocol stack between 5G-RG and AMF is defined in Figure 6.2.1-1.

For W-5GBAN, the W-CP protocol stack between 5G-BRG and W-AGF is defined in BBF TR-456 [9]. For W-5GCAN, the W-CP protocol stack between 5G-CRG and W-AGF is defined in WR-TR-5WWC-ARCH [27].

The protocol stack between 5GC/AMF and W-AGF is defined in clause 8 of TS 23.501.

The W-CP protocol stack:

supports transfer of NAS signalling between the 5G-RG and the W-AGF;
supports to carry AS parameters (e.g. SUCI or 5G-GUTI, Requested NSSAI and Establishment Cause) and NAS packets;
supports the setup, modification and removal of at least one W-UP resource per PDU session;
may support the setup, modification and removal of multiple W-UP resources per PDU session.

For the 5G-RG connected via NG-RAN the protocol stack defined in clause 8.2.2 of TS 23.501 applies with UE corresponding to 5G-RG.

6.2.2 Control Plane Protocol Stacks between the FN-RG and the 5GC p. 35

Reproduction of 3GPP TS 23.316, Fig. 6.2.2-1: Control Plane stack for W-5GAN for FN-RG

Figure 6.2.2-1: Control Plane stack for W-5GAN for FN-RG

The control plane protocol stack between FN-RG and AMF is defined in Figure 6.2.2-1. The W-AGF acts as an N1 termination point on behalf of FN-RG.

For W-5GBAN, the L-W-CP protocol stack, between FN-BRG and W-AGF is defined in BBF TR-456 [9] and WT-457 [10]. For W-5GCAN, the L-W-CP protocol stack between FN-CRG and W-AGF is defined in WR-TR-5WWC-ARCH [27].

6.3 User Plane Protocol Stacks for W-5GAN p. 35

6.3.1 User Plane Protocol Stacks between the 5G-RG and the 5GC p. 35

Reproduction of 3GPP TS 23.316, Fig. 6.3.1-1: User Plane stack for W-5GAN for 5G-RG

Figure 6.3.1-1: User Plane stack for W-5GAN for 5G-RG

The user plane protocol stack between 5G-RG and UPF is defined in Figure 6.3.1-1.

For W-5GBAN, the W-UP protocol stack between 5G-BRG and W-AGF is defined in BBF TR-456 [9]. For W-5GCAN, the W-UP protocol stack between 5G-CRG and W-AGF is defined in WR-TR-5WWC-ARCH [27].

The protocol stack between 5GC/UPF and W-AGF is defined in clause 8 of TS 23.501.

For the W-UP protocol stack:

W-UP supports at least one W-UP resource per PDU session. This will be the default W-UP resource.
W-UP may support multiple W-UP resources per PDU session and associate different QoS profiles (QFIs) to different W-UP resources.
W-UP supports transmission of uplink and downlink PDUs according to clause 4.5.
W-UP supports access specific QoS parameters that can be mapped from 3GPP QoS parameters (e.g.5QI, RQI) received from the 5GC.

For the 5G-RG connected via NG-RAN the protocol stack defined in clause 8.3.1 of TS 23.501 applies with 5G-RG replacing the UE.

6.3.2 User Plane Protocol Stacks between the FN-RG and the 5GC p. 36

Reproduction of 3GPP TS 23.316, Fig. 6.3.2-1: User Plane stack for W-5GAN for FN-RG

Figure 6.3.2-1: User Plane stack for W-5GAN for FN-RG

The user plane protocol stack between FN-RG and UPF is defined in Figure 6.3.2-1.

For W-5GBAN, the L-W-UP protocol stack between FN-BRG and W-AGF is defined in BBF TR-456 [9] and WT-457 [10]. For W-5GCAN, the L-W-UP protocol stack between FN-CRG and W-AGF is defined in WR-TR-5WWC-ARCH [27].
