3GPP 23.501 v20.2.0 — the document's own text
4.2.8.3.2 Requirements on Ta
Taught in 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth), 7. Roaming, other accesses, the edge and the outside (The 5G system architecture, overview).
Ta shall be able to
- Carry EAP-5G traffic and user location information before the NWt connection is established between the UE and the TNGF.
- Allow the UE and the TNGF to exchange IP traffic.
In deployments where the TNAP does not allocate the local IP addresses to UE(s), Ta shall be able to:
- Allow the UE to request and receive IP configuration from the TNAN (including a local IP address), e.g. with DHCP. This is to allow the UE to use an IP stack to establish a NWt connection between the UE and the TNGF.
NOTE: The "local IP address" is the IP address that allows the UE to contact the TNGF; the entity providing this local IP address is part of TNAN and out of 3GPP scope
In this Release of the specification, Ta is not specified.
