1. A method in a mobile station for avoiding interference to restricted access cells, the method comprising:
- detecting presence of a restricted access cell;
determining that a measured path-loss is larger than a path-loss threshold;
determining that the mobile station is not allowed to access the restricted access cell; and
barring a carrier frequency on which the restricted access cell is deployed when the measured path-loss is larger than the path-loss threshold and when the mobile station is not allowed access to the restricted access cell.

Abstract
A method in a mobile station for avoiding interference to restricted access cells, including detecting presence of a restricted access cell, determining that a measured path-loss is larger than a path-loss threshold, determining that the mobile station is not allowed to access the restricted access cell, and barring a carrier frequency on which the restricted access cell is deployed when the measured path-loss is larger than the path-loss threshold and when the mobile station is not allowed access to the restricted access cell.

8. A method in a base station for avoiding interference to restricted access cells, the method comprising:
-
determining that restricted access cells are present in a coverage area of the base station, and transmitting a path-loss threshold.

9. A method in a wireless communication device comprising:
-
receiving signals from at least a first base station; receiving at least a path-loss threshold from the first base station; measuring path-loss from a serving base station; determining whether the wireless communication device is allowed to access a restricted access cell detected by the device; determining whether the wireless communication device is required to reselect to a different frequency or radio access technology; reselecting to a different frequency or radio access technology in response to determining that the wireless communication device is not allowed to access the restricted access cell and that the measured path-loss from the serving base station is equal to or greater than the path-loss threshold. - View Dependent Claims (10, 11, 12)
