Claim 0:
1. A method implemented at a first network function (NF), comprising:
detecting that a path between the first NF and a second NF is failed or the second NF is failed, wherein the second NF maintains one or more data network connections or sessions established between one or more user equipments (UEs) and one or more data networks;
selecting an available second NF for the at least one of the one or more data network connections or sessions;
sending at least one address or address range of at least one UE corresponding to the at least one of the one or more data network connections or sessions and a respective priority metric of the at least one address or address range to the available second NE; and
the respective priority metric being associated with a valid time, and responsive to the valid time expiring, applying a predefined priority metric to the at least one address or address range, the respective priority metric having a higher priority than a priority of the predefined priority metric, the higher priority indicating a shorter path toward the at least one address or address range.
