9.11.3.90 Relay key response parameters

Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).

The purpose of the relay key response parameters information element is to transport the parameters of the key response for 5G ProSe UE-to-network relay or 5G ProSe UE-to-UE relay as specified in 3GPP TS 33.503 [56].

The relay key response parameters information element is coded as shown in figure 9.11.3.90.1 and table 9.11.3.90.1.

The relay key response parameters is a type 6 information element.
