Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for detecting a possible inter-radio access technology (IRAT) ping pong handover of a user equipment (UE) connection between a source radio access technology (RAT) communications network and a different target RAT communications network, where in an IRAT ping pong handover, the UE connection is handed over from a first cell in the source RAT network to a second cell in the target RAT network and then handed over back to a third cell in the sour…
