A method for coordinating seamless service continuity to Edge Application Server, EAS, at relocation in a cellular communications system, the method comprising: at an Application Function, AF,, sending, to a Policy Control Function, PCF, a steering request comprising application steering information that comprises a keepExistingPSA indication that indicates that a current user plane, UP, path to a current Data Network Access Identifier, DNAI, and to an EAS should be maintained while a new path to a new DNAI and EAS is established; at the PCF: receiving the steering request from the AF; generating Policy and Charging Control, PCC, rules based on the steering request, wherein the PCC rules comprise the application steering information comprising the keepExistingPSA indication; and providing the PCC rules to a Session Management Function, SMF; and at the SMF: receiving the PCC rules from the PCF; determining that a change of Protocol Data Unit, PDU, session anchor, PSA, for a PDU session, is to be performed from the source PSA to a target PSA; determining, based on the keepExistingPSA indication, that simultaneous connectivity over the source PSA and the target PSA is to be provided; and configuring the target PSA while maintaining the UP connectivity over the source PSA to the current Data Network Access Identifier, DNAI, and to the EAS. at an Application Function, AF,, sending, to a Policy Control Function, PCF, a steering request comprising application steering information that comprises a keepExistingPSA indication that indicates that a current user plane, UP, path to a current Data Network Access Identifier, DNAI, and to an EAS should be maintained while a new path to a new DNAI and EAS is established; at the PCF: receiving the steering request from the AF; generating Policy and Charging Control, PCC, rules based on the steering request, wherein the PCC rules comprise the application steering information comprising the keepExistingPSA indication; and providing the PCC rules to a Session Management Function, SMF; and receiving the steering request from the AF; generating Policy and Charging Control, PCC, rules based on the steering request, wherein the PCC rules comprise the application steering information comprising the keepExistingPSA indication; and providing the PCC rules to a Session Management Function, SMF; and at the SMF: receiving the PCC rules from the PCF; determining that a change of Protocol Data Unit, PDU, session anchor, PSA, for a PDU session, is to be performed from the source PSA to a target PSA; determining, based on the keepExistingPSA indication, that simultaneous connectivity over the source PSA and the target PSA is to be provided; and configuring the target PSA while maintaining the UP connectivity over the source PSA to the current Data Network Access Identifier, DNAI, and to the EAS. receiving the PCC rules from the PCF; determining that a change of Protocol Data Unit, PDU, session anchor, PSA, for a PDU session, is to be performed from the source PSA to a target PSA; determining, based on the keepExistingPSA indication, that simultaneous connectivity over the source PSA and the target PSA is to be provided; and configuring the target PSA while maintaining the UP connectivity over the source PSA to the current Data Network Access Identifier, DNAI, and to the EAS.
