Adaptive handover apparatus and method in a heterogeneous network environment

Image Number 6 for United States Patent #8126465.

An adaptive handover method in a heterogeneous network environment collects estimation information for a channel environment and integrates with a wireless device's geographic information to decide two groups of recursive parameters and a channel theoretical signal model. The model and the first group of recursive parameters are used to execute recursive iteration for a signal strength decay theoretical value. The obtained actual signal strength decay value from channel estimation, the second group of recursive parameters and the signal strength decay estimation value at previous iteration are used to execute channel-tracking recursive iteration for obtaining a signal strength decay tracking value. The current network status and the signal strength decay tracking value are used to predict and analyze system performance of heterogeneous networks. A decision is made based on each heterogeneous network's analyzed result, and an adaptive handover procedure is prepared by following the decision.
