- add set_function_spec_param() which configures RU_t instance depending on its
function(al split)
- export more functions like kill_RU_proc() so that they can be reused by
restart functionality
- when changing values RC.rrc[i]->configuration should be changed too
- then, RRC_RECONFIGURATION_REQ will pass the changed conf down until PHY
- give warnings at functions that are not implemented
- rename functions
flexran_get_tdd_ack_nack_feedback() -> flexran_get_tdd_ack_nack_feedback_mode()
flexran_get_ue_pmi() -> flexran_get_ue_wpmi()
Try to merge feature-68-enb-agent into develop
develop should be fast-forwarded later to this branch to complete the merge
This code does not compile yet. Among other things:
- the scheduler structure needs to be reworked for FlexRAN
- the config is structured differently. The files enb_config.{c,h} from develop
have been copied in here, the files with merge annotations are in
enb_config.{c,h}.before_merge
- the restart needs to be restructured, since the PHY vars data structure lives
in RC now
As reported by Emad Alizade:
According to "Issue255 256 257 paging reesta release" that has been
merged in develop version, we have a question: In rrc_eNB_free_UE()
function only all ulsch related memory of user has been cleaned, but
I think not only ulsch memory but also dlsch memory must be cleaned.
I tested the latest develop version and with repetition UE attach-detach
procedures we find that the dlsch memory has not been cleaned and after
repeat this sequence (45 times) assertion with cause UE_id!=-1 (no free
or exiting dlsch_context, dci_tools.c: fill_dci_and_dlsch() ) occurred
and no UE will be attached to system.
The fixes in this commit are from Emad Alizade.
Summary of changes:
- Implementation of paging (see issue #255 in gitlab)
- Implementation of RRC RE-ESTABLISHMENT (see issue #256 in gitlab)
- Implementation of RRC CONNECTION RELEASE (see issue #257 in gitlab)
Some modifications with timers have been done.
Expect (and report) problems, thanks.
What has been tested:
- monolithic eNB 5 and 10MHz with one commercial UE. UDP and TCP
traffic, uplink and downlink, with iperf (with a third party
EPC, not openair-cn). TCP downlink traffic is not stable.
Reason yet unknown. Will be fixed later.
