S1AP specs say:
initialUEMessage S1AP-ELEMENTARY-PROCEDURE ::= {
INITIATING MESSAGE InitialUEMessage
PROCEDURE CODE id-initialUEMessage
CRITICALITY ignore
}
So let's use "ignore", not "reject".
The online decoder http://asn1-playground.oss.com/ did
not decode a message encoded by the eNB because of this.
Only the S1AP messages captured while doing a simple connection
of one UE have been tested with the online decoder.
So, not all the S1AP messages have been checked, maybe some
instances of this problem are still there.
It does not seem to harm the actual UE<->eNB<->EPC communication
(because we don't check the integrity of messages or because
asn1c does not do it), so it's not a big deal.
- add function free_td() -> complements init_td() [seems to not be used, added
for completeness]
- add function free_td8() -> undoes init_td8() [free memory of 8-bit LLR Turbo
decoder]
- add function free_td16() -> undoes init_td16() [free memory of 16-bit LLR
Turbo decoder]
- change function free_tdavx216() -> undoes init_tdavx216() [free memory of
16-bit LLR Turbo decoder, AVX2 version]
- add free_lte_top() -> frees memory allocated by init_lte_top()
- change free_ul_ref_sigs() to set freed pointers to NULL
- add method free_transport() -> frees memory of ULSCH/DLSCH transport channels
- use the above functions when stopping/restarting the lte-softmodem
Through configuration, the lte-softmodem can be halted to await a
reconfiguration from the lte-softmodem. A mutex and condition variable are used
to implement this.
Furthermore, the dependance of lte-softmodem.c on FlexRAN has been reduced to
one include and the flexran_agent_start() call.
- 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()
