This commit refactors the PDU Session Resource Modify Response message structures to improve naming, documentation, and compliance with 3GPP TS 38.413 9.2.1.6. Changes in NGAP: - Rename qos_flow_tobe_modified_t to qos_flow_addmod_response_item_t to better reflect its purpose as a QoS Flow Add or Modify Response Item IE (as per specs) - Add mandatory AMF UE NGAP ID field to ngap_pdusession_modify_resp_t structure - Optimize field types: change nb_of_pdusessions and nb_of_pdusessions_failed from uint16_t to uint8_t (NGAP_MAX_PDU_SESSION limit) (ref 3GPP TS 38.413, 9.2.1.6) - Update PDU Session Modify Response encoder to use amf_ue_ngap_id from the message structure (pdusession_modify_resp_p->amf_ue_ngap_id) instead of retrieving it from UE context (ue_context_p->amf_ue_ngap_id) - Add comprehensive comments with 3GPP TS 38.413 section references throughout Changes in RRC/NGAP: - Populate amf_ue_ngap_id field in PDU Session Modify Response message from UE context - Update type reference to qos_flow_addmod_response_item_t

How to get support from the OAI Community
You can ask your question on the mailing lists.
Your email should contain below information:
- A clear subject in your email.
- For all the queries there should be [Query] in the subject of the email and for problems there should be [Problem].
- In case of a problem, add a small description.
- Do not share any photos unless you want to share a diagram.
- OAI gNB/DU/CU/CU-CP/CU-UP configuration file in
.confformat only. - Logs of OAI gNB/DU/CU/CU-CP/CU-UP in
.logor.txtformat only. - In case your question is related to performance, include a small description of the machine (Operating System, Kernel version, CPU, RAM and networking card) and diagram of your testing environment.
- Known/open issues are present on GitLab, so keep checking.
Always remember a structured email will help us understand your issues quickly.
