Supporting handover of multi-mode mobile terminal between heterogeneous networks

摘要

The present invention relates to supporting media independent handover of a mobile terminal to a heterogeneous network. Preferably, the present invention establishes a unified interface to an upper layer of the mobile terminal for managing messages to and from at least one of a homogeneous network and a neterogeneous network. Furthermore, the present invention requests a scan of a heterogeneous network different from a current network of the mobile terminal via the unified interface to determine the presence of an accessible link of the heterogeneous network for performing the handover.
