Method to handover a subscriber between different base stations in a multi-layered wireless network

A method for enabling a mobile station (MS) operative in a multi-layer wireless network, to be handed over to a target base station (BS) associated with one layer from among the multi-layer wireless network, being a layer different from the layer associated with a BS currently serving that MS, the method comprising:

• providing an MS being currently served by a serving BS associated with a first layer of the multi-layer wireless network, wherein said MS has not yet been provided with information that relates to a potential target BS associated with a second layer of said multi-layer wireless network;
• upon receiving an acknowledgement from the target BS indicating its capability to provide service to said MS, transmitting a message to the MS which comprises HO information that enables the MS to perform a fast network re-entry in order to communicate with the target BS;
• and
• initiating a handover procedure between the MS and the target BS, during which the MS performs a fast network re-entry.
