Ismael Gomez c2e9817f41 Possible solution to RLC Reestablishment 6 years ago
Ismael Gomez 14b526f2aa Add PDCP per-bearer reestablish 6 years ago
Andre Puschmann 3f613d7183 nas/gw/rrc: make LCID for DRB dynamic 
- add interface to RRC to allow NAS to query the DRB for a given
  EPS bearer id
- extend interface for NAS to setup GW to also pass LCID of bearer
- in NAS, use this new interface to pass actual LCID of the default
  DRB when creating the TUN device

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) 6 years ago
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

Andre Puschmann 7ca0988ea3 refactor RLC to use RAT-agnostic config 8 years ago
Andre Puschmann 8dbabb2834 rework bearer/LCID handling 
This is a larger patch that reworks the LCID handling throughout the
code.

- It first moves the RB/LCID mapping out of common.h into the RRC object
  because different RATs may have different mappings.
- It adds a interface to RRC that other objects like RLC/PDCP/etc. may
  use to get the bearer name of a specific LCID.
- The patch also introduces a PDCP config class.
