Author SHA1 Message Date
Jan a786d1dda0 Update security algorithms in epc.conf 
Added EEA3 and EIA3, since they were missing from the description completely.
I also included EIA0 with a remark, since my understanding is that the epc supports it, but most UEs reject it because it must only be used for unauthenticated emergency calls.

Pedro Alvarez ca603810ce Adding Downlink data notification and paging functionality to the EPC. 
This entails:

  * Adding S1AP paging messaging to the MME.
  * Adding the Downlink Data Notification, Donlink Data Notification Acknoledgment, and Downlink Data Notification Failure Messages.
  * Adding the logic at the GTP-U to detect that Downlink Data notification needs to be sent.
  * Proper handling of the new GTP-C messages at the MME GTPC and SPGW GTPC classes
  * Add queuing mechanisms at the GTP-U while waiting for paging response. Queue is flushed when paging fails (timeout or other).
  * Make sure eNB's SCTP information is properly stored.
  * Make sure UE's GUTI information is properly stored.
