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.

Pedro Alvarez 5f7b6ba79e Split GTP-C and GTP-U functionality into seperate classes in the SPGW. Added GTP-U specific logging in the EPC. Added handle_s11_pdu function to both the MME GTP-C entity and the SPGW GTP-C entity. 6 years ago
