- Refactor ngap_paging_ind_t (openair2/COMMON/ngap_messages_types.h):
- optional paging_drx and paging_priority as pointers
- TAI list as tai_list[] and n_tai
- add optional IEs: Paging Origin, Paging Attempt Information,
UE Radio Capability for Paging.
- Introduce nr_tai_t, ngap_paging_attempt_info_t, ngap_paging_origin_t;
- generate paging enums via FOREACH macros.
- Add NGAP Paging encode/decode/eq/free in openair3/NGAP/ngap_gNB_paging.c
(encode_ng_paging, decode_ng_paging, eq_ng_paging, free_ng_paging).
- Replace inline Paging decode in ngap_gNB_handle_paging() with
decode_ng_paging() and add error handling; add eq_ngap_plmn() in
ngap_common.
- Update rrc_gNB_NGAP.c to use tai_list/n_tai and optional paging_drx
when forwarding paging to F1AP.
- Add ASN.1 includes for Paging in ngap_msg_includes.h; register
ngap_gNB_paging.c in root CMakeLists.txt.
- Add NGAP unit test (openair3/NGAP/tests/ngap_lib_test.c): encode/decode
roundtrip for Paging; tests subdirectory and executable under
ENABLE_TESTS in openair3/NGAP/CMakeLists.txt.
ngap_common.h is for common IEs enc/dec functions, utilities
should go into a separate file. Changes in this commit:
* Add ngap_utils.h (utilities)
* Move helper macros (NGAP_ERROR, NGAP_DEBUG, NGAP_FIND_PROTOCOLIE_BY_ID, etc.) to ngap_utils.h
* Move equality check macros (_NGAP_EQ_CHECK_*) to ngap_utils.h
* Clean up includes
This change is preparatory to the introduction the paging lib with unit
tests, with the goal of reducing the inter-dependency between concurrent
NGAP libs.
These conversion functions will be needed across different
NGAP libraries upon refactoring: tnl_to_bitstring, bitstring_to_tnl
Therefore, they are moved to the common lib.
PDU session related NGAP messages do not belong to NAS procedures lib.
* Create ngap_gNB_pdu_session_management.c and .h
* Move out ngap_gNB_pdusession_setup_resp, ngap_gNB_pdusession_modify_resp,
ngap_gNB_pdusession_release_resp from ngap_gNB_nas_procedures.c
* Move encode_ngap_pdusession_setup_response_transfer to ngap_common.c:
this transfer IE is common used both in PDU Session Management and
Initial Context Setup, so it's moved to the common lib
* Add ngap_gNB_pdu_session_management.c to CMakeLists.txt
This commit introduces the NG Mobility Management Procedure known as
Handover Resource Allocation. The inbound message is sent by the AMF
and is known as Handover Request.
Major changes:
(0) Add Handover Resource Allocation initiating message decoding
* add case for NGAP initiating message and unsuccessful message decoding
(1) handle Handover Request on the target NG-RAN
(2) decode NG Handover Request message
(3) process payload, e.g. create UE context,
store IDs, set UP security and trigger bearer setup

This commit introduces the NG Mobility Management Procedure known as
Handover Preparation. The outbound message is sent by the source NG-RAN
and is known as Handover Required.
* introduce NGAP library for Mobility Management
* introduce NGAP IEs encoder functions for Handover Required and relevant common IEs
* handle RRC trigger in NGAP and Send NGAP Handover Required to the AMF
Co-authored-by: batuhan duyuler <batuhan.duyuler@firecell.io>
* Functions added:
decode_ngap_guami
decode_ngap_UEAggregateMaximumBitRate
decode_ngap_nssai
decode_ngap_security_capabilities
decode_ngap_mobility_restriction
* Adopt these functions in the common NGAP library
* new struct definition including both NGAP cause group and value
* add encoding function, temporarily in ngap_common.c
(in the long term to be place in a enc/dec NGAP library)
* extend Radio Network cause enum values
* add cause member to Setup Failure
ENB_MODE is a cmake option to swap the order of include directories.
This has historical reasons; before OAI used cmake, it was very
sensitive to the order of includes. Nowadays, the order does not matter.
Remove this option, and fix the compilation issues that arise while
doing so.
OAI is riddled with boolean_t, FALSE, TRUE, etc. This makes no sense, as
there is a standard bool type, and could lead to nasty bugs if a
definition of a bool is non-standard (0 == false, true == !false). This
commit removes all non-standard bools in the whole project.
