Ismael Gomez 6348ddefd5 Add option to run prach_worker in the caller thread instead of by a background worker. This is useful when running simulations with ZMQ, to avoid the prach worker to take too much time and miss the RAR deadline 2020-12-26 23:49:42 +01:00

Andre Puschmann d5daf60773 pdu_test: add unpacking test for DL-SCH PDU containing TA command 2020-12-18 12:28:52 +01:00
Andre Puschmann c5514d7f80 pdu: fix to_string() for TA command 
the get_ta_cmd() is returning uint8_t which stringstream
interprets as ASCII character by default. So the log message is bogus.

Pedro Alvarez 0ad0e9acac Make sure that RLC entity is only re-created if it switches modes. 2020-12-18 10:52:51 +00:00
Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

Andre Puschmann bc4c9606ce rlc_am: add extended bearer metrics 
this patch adds support for measuring the:
* SDU rx latency (Average time in ms from first RLC segment to full SDU)
* amount of buffered bytes (sum of payload of PDUs buffered in rx_window)

the implementation is using std::chrono

Andre Puschmann 9133135e12 rlc_tm: remove error from log when RLC TM PDU can't be sent 
RLC TM can't be segmented so it may happen that a PDU
cannot be sent because the grant is too small. That is not
an error and should only be logged in info.
