Andre Puschmann 926f256afa fix RLC dummy class that was missing suspend/resume 2020-02-03 16:26:15 +01:00
Andre Puschmann a32d4ebf59 move PRACH config check into cfg parser 2020-02-03 16:26:15 +01:00
Andre Puschmann 179fd394b2 enb: add SRB2+DRB1 to scheduler AFTER receiving Reconfig Complete 
this commit fixes and issue where, after receiving paging and the resulting
PRACH from the UE, the eNB would create DRB1 and already schedule DL traffic
on this bearer. However, since the UE has not received the reconfig message
yet, the DL traffic is dropped since DRB1 isn't set up yet.

the commit also does not reset the BSR state of the bearer inside MAC since
this caused to a stall of the received DL PDU. The value would initially be set to
a non-zero value (after receiving the DL PDU from EPC). But when the bearer
was (re-)introduced to MAC, it would reset the BSR to zero, and, since
MAC never polls RLC, the PDU wasn't sent down until the next PDU arrives
and sets the BSR to a non-zero value again.

Andre Puschmann ad304207b3 patch PRACH offset parameter for 6 PRB 
the 6 PRB eNB requires a different PRACH offset than the default
value of 2 in the SIB1 example. In order to avoid having
to use a separate SIB config with just a single different value,
the patch patches the value to the only right configuration, if it's wrong.
It continues operation but still issues a warning so the user
can change it in the config.

Andre Puschmann fef6893ce4 make user activity handling independent of system time 
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.

Andre Puschmann 6ec573987a remove default value for 'blocking' param from pdcp::write_sdu() 
there were two defaults and one was shadowing the other. This
commit removes both defaults and uses blocking-mode for RRC
calls to PDCP in the UE. The eNB write_sdu() uses the non-blocking
mode by default. We have to review the eNB's RRC perhaps and use blocking
there too and non-blocking only for data plane
