  That's how it works.  The phone disconnects from the access point in
order to save battery life.  Since it's disconnected, when it goes back
online, it has to re-connect and re-authenticate.

  You can use session caching.  See the "cache" subsection of the "eap"
module.  It will make later authentications faster.  But it won't stop
them from coming.

  In this case, the WiFi phone is asking for re-authentication, and the
NAS is requiring re-authentication.  RADIUS is just receiving the
authentication requests, and processing them.
