Robert Schmidt ca2f91072a F1AP: on UEContextRelCmd, DU distinguishes whether UE is out of sync 2019-01-18 16:44:00 +01:00
Robert Schmidt 7df8257526 F1AP: when UL_sync failure, send UEContextRelReq 
When a phone loses connection, it should not simply be removed but first
CU should be informed which will send a ContextRelCmd. Correspondingly,
when the RRC releases the UE, it does not send a UE Context Release Req

Robert Schmidt f3f2bc584f F1AP_UE_CONTEXT_RELEASE_REQ: implement in DU

* message is dispatched to correctly in DU_TASK
* sender correctly fills IDs and cause and sends

Robert Schmidt d9bf26b9e8 Sort FlexRAN statistics by user before sending 2018-12-05 11:46:54 +01:00
Robert Schmidt 62b89f828a FlexRAN: Circumvent different RRC/MAC layer user ID sorting 
* RRC and MAC might sort users differently
* therefore, we have to "reverse lookup" the MAC ID from the RNTI when filling
  user info
* For this purpose, add RAN API function flexran_get_mac_ue_id_rnti()

Robert Schmidt 54da66eeac Bugfix: Rename proto_agent global channel variable 
The PROTO_AGENT variable holding the channel for various was named as the same
one for FlexRAN. In C, global variables with the same name are merged into one,
which had the effect that the same queues where used for PROTO_AGENT and
FlexRAN, locking the FlexRAN RX thread. Renaming the PROTO_AGENT variable (it
was introduced second) resolves this issue.

Robert Schmidt 0efde02161 Sanitize link_manager interface, correct in FlexRAN/PROTO_AGENT 
This commit cleans up the link_manager interface:
* don't provide peer_addr/port in create_link_manager() (for TCP/SCTP it is not
  needed, so in the UDP case in needs to be set explicitly)
* Make FlexRAN connect again (correct hardcoded address)
* Fix FlexRAN: retain the manager pointer
* Fix FlexRAN: store receive_queue pointer
* the link_manager's sender thread passes the correct peer_addr/port for the
  UDP case

Robert Schmidt 1fc631e2a4 RAN API RRC part: Change interface to RNTI, change flexran_get_aperiodic_cqi_rep_mode() 
* the RAN API RRC part now takes rnti and does not look it up in the MAC every
  time again
* the function flexran_get_aperiodic_cqi_rep_mode() has been changed to return
  a proper protobuf variable, not OAI typedef
