Abstract:
Inter-radio access technology (IRAT) ping pong handover of a user equipment (UE) connection between a source radio access technology (RAT) communications network, e.g., LTE, and a different target RAT communications network, e.g., UTRAN, is detected. A control node determines IRAT ping pong handover information and evaluates an IRAT handover request message for the UE connection from the source RAT network with respect to the handover ping pong information. Based thereon, the node determines that the UE connection meets one or more ping pong conditions associated with the handover ping pong information and provides an indication of an IRAT ping pong handover condition to a base station in the source RAT network to allow the base station to make mobility adjustments.
