Relay Service Code tag '80'
Contents:
Indicates the connectivity service that the ProSe UE-to-network relay provides to public safety applications.
Coding:
As defined in TS 24.334.
PDN type tag '81'
Contents:
Indicates the IP version of the PDN connection to be used for the relayed traffic associated with a Relay Service Code.
Coding:
A value of '01' indicates IPv4, a value of '02' indicates IPv6. All other values are reserved.
APN tag '82'
Contents:
Indicates the PDN connection that the ProSe UE-to-network relay uses for the relayed traffic associated with a Relay Service Code. If this TLV is missing, then the default APN is used for the PDN connectivity.
Coding:
A network access point name
ProSe Relay UE ID tag '83'
Contents:
Indicates the link layer identifier used for direct communication associated with a Relay Service Code.
Coding:
As defined in TS 24.334.
Security Content tag '84'
Contents:
Parameters related to the relay discovery.
Coding:
