Abstract
In accordance with an example embodiment of the present invention, a method comprises receiving at a first network node an inter-radio access technology (RAT) signaling message from a source node, a handover signaling message including inter-RAT handover information including a START packet switched (START PS) value; determining whether the START PS value is reliable prior to handing over to a second network node at least based in part on the source node from which the START PS value is received and inter-RAT handover information reliability indicator; building an inter-RAT handover information reliability indicator to indicate whether the START PS value is reliable and including the inter-RAT handover info reliability indicator in a second signaling message; and forwarding the second signaling message to the second network node.
