According to 4.9.1.3.3 of 3GPP TS 23.502: > 2a. - 2c. The S-RAN sends the Uplink RAN Status Transfer message to the S-AMF, > as specified in TS 36.300 [46] and TS 38.300 [9]. The S-RAN may omit sending > this message if none of the radio bearers of the UE shall be treated with PDCP status preservation. TS 38.300 says: > For DRBs not configured with DAPS, the source gNB sends the SN STATUS TRANSFER message to the target > gNB to convey the uplink PDCP SN receiver status and the downlink PDCP SN transmitter status of DRBs for > which PDCP status preservation applies (i.e. for RLC AM). The uplink PDCP SN receiver status includes at > least the PDCP SN of the first missing UL PDCP SDU and may include a bit map of the receive status of the out > of sequence UL PDCP SDUs that the UE needs to retransmit in the target cell, if any. The downlink PDCP SN > transmitter status indicates the next PDCP SN that the target gNB shall assign to new PDCP SDUs, not having a > PDCP SN yet. i.e., for DRBs for which PDCP status preservation applies (i.e. for RLC AM), which is is our case. This commit introduces full support for NG-RAN Status Transfer message handling (TS 38.413 §9.2.3.13-14) in CU. It enables correct state transfer of PDCP COUNT values (SN + HFN) during mobility or recovery scenarios. Summary of changes - NGAP: * Added encoding/decoding support for UL/DL RAN Status Transfer message * Defined structures for: ngap_drb_count_value_t, ngap_drb_status_t, ngap_ran_status_container_t, ngap_ran_status_transfer_t
