[{"name":"SP-220335","title":"SMF+PGW-C assigned PDU Session ID","source":"Huawei, HiSilicon","contact":"Susan SHI","contact-id":81582.0,"tdoctype":"CR","for":"Approval","abstract":"Add a new option to resolve the PDU Session ID conflict. Summary of change: When the SMF+PGW-C is expected to allocate a PDU Session Id, if handover between EPS and EPC\/ePDG is required, based on operator's configuration, either - the SMF+PGW-C may query the UDM for any PDU Session ID(s) that are already assigned by the same or different SMF+PGW-C by invoking Nudm_UECM_Get service operation. - When the SMF+PGW-C establishes the PDN connection successfully, the SMF+PGW-C may perform UDM registration using the Nudm_UECM_Registration service operation. Add a note clarifying the scenario that requires UDM interaction. Add a new sub-clause for PDN connection release, which is generic to any PDN connection with UDM registration. Or - In the case the same PCF is deployed to serve all PDN connections for which handover between EPS and EPC\/ePDG is required, of the UE accessing the EPS, the PCF responds the list of allocated PDU Session ID(s) to the SMF for PDU Session ID re-assignment if the PCF finds the received PDU Session ID duplicates with the locally stored allocated PDU Session ID(s). Otherwise if there is no PDU Session ID duplication, then no impact on the normal PDN connection procedure.","secretary_remarks":"LATE DOC: Proposed Update to 23.502 CR3135R4 in SP-220041 to resolve Working Agreement issue.
