Why does my MME request 2 different DIAMETER E-UTRAN vectors for the same UE?
Posted on 11. Jan, 2012 by Vitty
When my UE initially attaches to the network I see that the MME makes 2 separate DIAMETER Authentication Information Requests to the HSS and receives 2 different E-UTRAN vectors back in return. The first vector I receive back seems to be the one that de-ciphers my NAS messages. What is the second vector used for and how do you know when to use it instead of the first?
Thanks!

Usually one request should be sufficient, better check with MME vendor why 2 requests. It may be storing it for next use ???
