1. Fix code generated from ASN.1 of F1AP v15.4.0 failed to be compiled
2. Fix incorrect UPER encoding for empty extensible SEQUENCE in 38.331
3. Fix the problem that duplicate type names exist in OPEN TYPE
Fix the problem that duplicate type names exist in OPEN TYPE.
The following excerpt of ASN.1 of X2AP is one example.
HandoverRequestAcknowledge-IEs X2AP-PROTOCOL-IES ::= {
{ ID id-Old-eNB-UE-X2AP-ID CRITICALITY ignore TYPE UE-X2AP-ID PRESENCE mandatory}|
{ ID id-New-eNB-UE-X2AP-ID CRITICALITY ignore TYPE UE-X2AP-ID PRESENCE mandatory}|
...
}
1. Fix the problem of compiling NR_RangeToBestCell.c of NR-RRC 15.3.0
2. Fix the problem that default OCTET/BIT STRING value not used in APER
3. Add support of extension group inside CHOICE type used in LTE-RRC 15.3.0
4. Fix the problem that NGAP 15.0.0 ASN.1 can not generate C files
1. Fix the problem of compiling NR_RangeToBestCell.c of NR-RRC 15.3.0
2. Fix the problem that default OCTET/BIT STRING value not used in APER
3. Add support of extension group inside CHOICE type used in LTE-RRC 15.3.0
4. Fix the problem that NGAP 15.0.0 ASN.1 can not generate C files
- install package 'vim-common' to have 'xxd' needed by the compilation
process of the T tracer
- change the way xxd is called so that no file is created in case
of error
1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
feature in generate_asn1.
2. It's no need to patch the C header files generated from
LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
object class feature by asn1tostruct.py.
This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :
https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group
This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.
Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.
There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :
https://github.com/brchiu/openair-cn/tree/new-asn1c
Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.
Note: Community version of asn1c is keeping evolved to provide better usage.
-- Stability issues when installing packages for USRP variants on new VM
It sometimes timed-out
Added loop up to 5 tries to add apt-repository
-- Temporary merge during MergeRequest processing now returns an
error when there are any conflicts
Will stop the whole build
-- Physical simulator now has a XLST for the XML result
