Authentication-Information-Request message is sent by MME and SGSN both while doing authentication procedure for an UE. Since this message can be triggered by either MME or SGSN, this message has two AVPs named as "Requested E-UTRAN Authentication Info" and "Requested UTRAN/GERAN Authentication Info" and used by MME and SGSN respectively.
