Abstract
A Session Management Function, SMF, () determines that a first data path for a Packet Data Unit, PDU, session between an application client () and a first edge application server, EAS, () should be relocated from a first local PDU session anchor, PSA, () and a first uplink classifier and branching point, ULCL/BP, () to a second PSA () and a second ULCL/BP (). Further, the SMF () determines an edge client subnet, ECS, associated with the second PSA (). Further, the SMF () sends, to an application function, AF, () associated with the application client (), a notification of the relocation. The notification includes an identifier of the ECS and a data network access identifier, DNAI, associated with the second PSA (). From the AF (), the SMF () receives a response that includes an identifier of a second EAS () and the DNAI associated with the second PSA (). Based on the response, the SMF () establishes a second data path for the PDU session between the application client () and the second EAS () via the second PSA () and the second ULCL/BP ().
