Xavier Arteaga 67935d2b99 SRSUE: RRC blocks MAC RA procedure during reestablishment 5 years ago
Andre Puschmann 71c83bd0e0 fixing typo in RRC proc 5 years ago
Andre Puschmann 8ef0d6c6ca do not automatically consider cells for which a measurment has been received as "in sync"
the in_sync flag has been misused in some parts of the code
receiving a PHY measurement for a cell does not automatically
mean that we are "in sync", as it is used in RRC as a condition
to indicate if we are camping on cell

the in_sync/out_of_sync condition should only be altered by the
corresponding functions sent from the PHY for the currently selected
cell (and not automatically for all cells)

the commit also removes the deletion of cells which are not "in sync"
from the list of neighbor cells. Instead, RRC calls a clean-up function
peridically that deletes old cells eventually.

Francisco Paisana f2d88e5a5b simplified NAS rrc connection request procedure
move non-type-specific methods of proc_t to its base class.

made the NAS procedures more event trigger/reaction-based.

Andre Puschmann c24b25f42e after RLF store PCI of current serving cell
the PCI is needed for the reestablishment request in case
the new serving cell has changed
5 years ago
Andre Puschmann c1da02cd07 after initiating reestablishment, we need to perform cell reselection immediatly
before cell reselection was postponed to the next TTI but this is not possible in
the case where the serving cell changes.

if the "old" serving cell is no longer suitable, we would directly go to RRC IDLE below.
Therefore we need to select the new serving cell before sending the reestablishment
request.

this is tested in TC_8_5_1_1

Andre Puschmann c5f52adfba nas: fix issue in which NAS wouldn't allow to attach once it failed
the main issue was the plmn_selected variable. the solution
was to create a function to enter the deregistered state that resets the variable
and performs all other actions that need to be performed, like clearing
EPS bearers.

The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7

RRC-PHY interface (#639)
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)

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. 6 years ago

Andre Puschmann 58763fb714 stack: move initialization of log object into ctor
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.

- add interface to RRC to allow NAS to query the DRB for a given

- 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
