There were some important conflicts in openair3/ocp-gtpu/gtp_itf.cpp
I rewrote a bit the function Gtpv1uHandleGpdu(). It might have been
done wrongly.
To be tested and fixed if needed.
To redo the merge, if needed:
git checkout 9b2a163ebb
git merge 5ea828e149
After this commit, only the RNTI is used as an identifier in the MAC.
Further, it removes some module_id, but a lot of them remain (the goal
to remove all is still far from us)
1. Removed SDAP struct from protocol context.
2. Added configuration for the SDAP.
3. SDAP doesn't use pdcp_entities, the values come from function arguements.
4. Make nr_pdcp_ue_manager accessible from SDAP.
5. Avoid using the PDCP locking mechanism in SDAP.
6. Removed nr_pdcp_find_entity_sdap function.
7. Rename dummy eNB function to make GTP compile (no SDAP).
8. Fix: Regression issues with LTE
9. Fix: Regression issues with NR CU/DU
-Required for interoperability with Accelleran CU and OAI CN
-Currently hardcoded values, to be modified so that they are parsed from the DU config file
-After this modification Accelleran CU sends gNBCU configuration update
-Add also a temporary artificial trigger just to be able to test with OAI UE
-Comment out most of the part of the UE context release command handler function at the DU in order to separate properly the RRC from F1AP functionality later.
-F1 message successfully encoded at the CU (including SRB2, DRB and F1-U tunnel configuration) and received from the DU.
-Next steps: handling of UE context modification request at the DU and triggering the UE context setup response towards the CU.
-Trigger UE context setup response at the DU and RRC Reconfiguration at the CU upon reception of UE context setup response.
-Pending: The DU should generate some updates on the master cell groupconfig based also on the received UE capabilities and add them in
the UE context setup response message so that they can be included in the RRC Reconfiguration message sent from the CU. For the moment the
corresponding function is empty.
-Next steps: trigger UE context modification procedures
-Include UE_Capability_RAT_container_list in UE context setup request so that it gets processed at the DU
-Next steps: DU should store and process the UE capabilities and generate updates in master cell group config
to be included in UE context setup response. Then upon reception of UE context setup response, the first RRC Reconfiguration
can be triggered at the CU with the updates on master cell group config.
