Francisco Paisana 5953d5ef96 fixed some potential bug related to timer getting stopped, but signaling that it expired 5 years ago
Francisco Paisana 551192705e allow for pre-reservation of timers vector and priority queue 5 years ago
Francisco Paisana 50a1c9d557 addressed potential overflow, and extended timer test to check if ordering is working correctly 5 years ago
Francisco Paisana 349646a9da created a new class for timers. It uses a priority queue to avoid incrementing all timers every tti (step_all() went from O(N) to O(1)), and that is not bounded in number of timers. Not being bounded will be useful for layers that require one or more timers per UE 5 years ago
Francisco Paisana 15bde8660a getting a future of an already finished proc is dangerous 5 years ago
Francisco Paisana 248583ecdf added extra logging and removed uneeded member from proc_t 5 years ago

Francisco Paisana f2d88e5a5b simplified NAS rrc connection request procedure 
move non-type-specific methods of proc_t to its base class.
procedure state machine was simplified via a future-type. Now procedures dont get stuck until the user reads the procedure outcome.
made the NAS procedures more event trigger/reaction-based.

Ismael Gomez 1d83bb08e2 Changes in ACK procedure to support CA. Tested 1 cell in SISO/MIMO 5 years ago
Andre Puschmann d8fedf2e19 fix parsing of corrupted MAC PDUs 5 years ago
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
 5 years ago
Francisco Paisana 2fb830fcfa moved cell search to background task thread pool, and provided a stack interface to rrc to call "start_cell_search". Once completed, the background task signals back to RRC 5 years ago

happens when very small grant is provided and the status
PDU generation fails because of a too small grant

 5 years ago
Andre Puschmann 5189bbad69 add stop() to logger_file 
this allows to close and currently running log process, flush the content
to the file, continue logging during that time, open a new file

basically it allows to use the logger_file multiple times without
needing to destroy the object

this is used in the UE tester to write each testcase into a separate
log file

Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Closes: #358
Closes: #363

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)

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.

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.

make EIA and EEA algorithms configurable (#323) 
this patch allows to configure the EIA and EEA algorithms
the UE uses and announces during attach. They can
be specified as a comma-separated list.

The patch also removes a dedicated NAS config class and uses
the default nas_args_t type for this. There was a full
duplication of members before.

The patch also converts nas_args_t and usim_args_t into a class
with a default constructor that initialize all booleans.

Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM 
- With the current default tx queue length (16 SDUs) the BSR reported by the UE
  is too low if the size of the SDU is relativly small (e.g. 100 B).
  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.
