Patent ID: 7940727

Claim:
A method for cell re-selection in a dual mode terminal supporting Global System for Mobile communication (GSM) and Wideband Code Division Multiple Access (WCDMA), the method comprising: measuring a plurality of cell re-selection parameters for a WCDMA cell and a plurality of cell re-selection parameters for GSM cells when attempting a cell re-selection from a GSM cell to the WCDMA cell; determining a plurality of additional weight values for cell re-selection based on whether the WCDMA cell has previously been used by the terminal; comparing one of the plurality of cell re-selection parameters for the WCDMA cell with a sum of one of a plurality of weight values and at least one of one of the plurality of additional weight values and one of the plurality of cell re-selection parameters for the GSM cells, and determining whether the WCDMA cell is re-selected in accordance with results of the comparisons.
