This functions fills the ULSCH CQI indication message incorrectly. Also,
it should only be triggered when the eNB requests CSI. We disable it
here and a subsequent commit enables it again.

Robert Schmidt a51dc94e8b Set correct UE ID in Kenb Refresh Req 
NAS triggered the Kenb Refresh Req always for (hardcoded) UE 0. This
fixes this by setting the correct UE ID.

An effect of this was that the Kenb would always be set for UE 0,
regardless for which UE it was actually intended. This led for integrity
check failures for every UE with ID > 0.

Robert Schmidt b6d466d772 FlexRAN: reimplement timers without ITTI 
The timer code used to trigger periodic statistics message sending used
ITTI. Together with a high frequency reporting (e.g. 1ms), this resulted
in high CPU usage. This commit reimplements this:
* using a thread that is synchronized to the RU (if there is no MAC, we
  assume there is no RU generating a tick so we create the tick source
  ourselves)
* no RB trees but plain arrays
* smaller interface for users
* slight user interface changes
* remove stopped timer state: such timer might be simply removed
* remove one-shot timers

Robert Schmidt bbedd315e7 Correctly link lte-uesoftmodem(-nos1) (hack) 
Although not used in the UE, we currently need to link the F1 library into it.
This is because we do not define ASN_DISABLE_OER_SUPPORT (otherwise, F1 has
compilation problems). In this case, some functions are apparently not
correctly defined, giving linker errors in the UE. Linking F1 in solves the
problem.

This is a hack. It would be better to be able to define ASN_DISABLE_OER_SUPPORT
and have no compilation errors or compile everything with
ASN_DISABLE_OER_SUPPORT except F1. I did not do this because I did not find
another way than add target_compile_definitions() to every target except F1
which adds many lines just so that one target (F1 ASN.1) compiles correctly (in
other words, F1 needs to be fixed).

 2019-02-07 18:00:20 +01:00
Robert Schmidt beec74b01a Correctly stop link_manager sender and receiver threads 
This changes the destroy_link_manager() function to:
* call a new function message_get_unlock() to unlock the sending thread from
  its blocking message_get()
* calls pthread_cancel() on the receiving thread, because this unlocks any
  blocking read from a file descriptor

The same message_get_unlock() function has been added ringbuffer_queue to keep
the interfaces the same (it does nothing, because ringbuffer_queue is
non-blocking).

Robert Schmidt d9d6ce374f Perform S1 UE Context Release Complete after corresponding F1 message 
This commits isolates the S1 UE Ctxt Rel Complete and GTP Tunnel Delete
Requests in functions and calls these function in the original place
(rrc_rx_tx()). The same functions are then used in the F1 UE Ctxt Rel
Complete handler to perform the same functionality, i.e. forward the UE
Ctxt Rel Complete message to the MME and free outstanding resources (RRC
context, GTP tunnels, S1 context).
