Xavier Arteaga 7629863c5a SRSUE MAC: 36.331 v10 9.2.2 MAC main config defaults does not include RACH 2019-05-27 12:37:52 +02:00
Xavier Arteaga 080b4a327c SRSUE: Refactored asynchronous cell and ue_radio. CA Fixed. 2019-05-17 18:13:51 +02:00
Andre Puschmann 65f50cd7ba introduce new UE layer design 
- abstract UE object now consists of a radio, a PHY, and a stack layer
- add new stack abstraction layer that combines MAC, RLC, RRC, PDCP, NAS and GW
- PHY layer now has a single stack interface and does not talk to MAC and RRC seperatly

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.

Andre Puschmann d6196ba234 simplify RRC-NAS interface and only have msg as param (RRC selects LCID) 2018-12-10 17:48:52 +01:00
Andre Puschmann c3441046c9 simplify RLC buffer status query procedures 
- add a simple and low-overhead has_data() method to check whether
  an RLC entity has data to transmit or not
- use this method for all calls that are actually not interested
  in the amount of data to send
- use the more expensive get_buffer_state() for all cases where
  the actual size of the buffer is of importance
