Francisco Paisana 92b4b168fe added default rlc um and am in the interface as factories 2019-07-05 10:44:15 +02:00
Francisco Paisana 58e2e51044 removed rlc_interfaces. The rlc_cnfg types are now part of the rrc_interface_types. Removed implicit RB initialization in the RLC. 2019-07-05 10:44:15 +02:00
Francisco Paisana bb0dbf0f1c created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far. 2019-07-05 10:44:15 +02:00

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) 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
