摘要： A method and apparatus for scaling a VNF on a first PoP associated with at least one wireless device (WD) to a second PoP. A probabilistic estimate of a likelihood that the WD(s) will be handed over to at least one candidate PoP is generated and a VNF state associated with such candidate(s) is scaled and populated with state context information related to a handover of the WD(s) from the first PoP to the candidate(s). The second PoP is identified from the candidate(s) prior to handover using the probabilistic estimate. Thereafter the VNF is scaled from the first PoP to the second PoP, followed by handover of the WD(s) from the first PoP to the second PoP.
