9.11.3.89 Relay key request 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 request parameters information element is to transport the parameters of the key request 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 request parameters information element is coded as shown in figure 9.11.3.89.1, figure 9.11.3.89.2 and table 9.11.3.89.1.
The relay key request parameters is a type 6 information element.

| Relay service code (octet 4 to 6)The relay service code contains 24-bit relay service code as defined in 3GPP TS 24.554 [19E].Nonce_1 (octet 7 to 22)Nonce_1 is the 128-bit nonce value as defined in 3GPP TS 24.554 [19E].UE ID type (UIT) (octet 23, bit 1)Bit10 SUCI1 CP-PRUK IDUE ID (octet 23+1 to n)UE ID indicates the value of the 5G ProSe remote UE identity or the 5G ProSe end UE identity.If the UE ID type is set to SUCI, the UE ID is coded as 5GS mobile identity IE starting from octet 2 with the Type of identity set to "SUCI" (see clause 9.11.3.4).If the UE ID type is set to CP-PRUK ID, the UE ID is coded as the CP-PRUK ID as defined in 3GPP TS 33.503 [56]. |
