Claim of US Patent No. 9,155,036

1. A method of operating a wireless communication device, comprising:
receiving system information from a base station of a visited wireless communication network, wherein the system information
includes at least a portion of cell selection parameters for a wireless cell of the base station;

calculating a cell selection metric from the cell selection parameters and a cell selection offset stored in the wireless
communication device, wherein the cell selection offset causes the cell selection metric to indicate that the wireless cell
is not suitable for communications;

receiving a request for a data channel from an application executing on the wireless communication device;
in response to the request, recalculating the cell selection metric from the cell selection parameters without the cell selection
offset; and

determining whether the wireless cell is suitable for communications based on the recalculated cell selection metric.
