Abstract
A method and system for inter-operator handover in a telecommunications network comprising a greenfield WCDMA operator and a GSM/WCDMA operator. When a mobile terminal of the greenfield operator is moving from the coverage area of the home network to the GSM/WCDMA area, a neighbor list of GSM cells is provided to the mobile terminal for handover to a GSM cell when the home network coverage is not available. When the mobile terminal is returning home from the GSM/WCDMA area, a neighbor list of the home cells is provided to the mobile terminal so that the greenfield mobile station is connected to its home network whenever there is coverage. Preferably, the neighbor lists are provided to the mobile terminal only in the connected mode.
