Claim
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.
2. The method according to claim 1, receiving the path-loss threshold from a first base station.
3. The method according to claim 1 further comprising determining that the measured path-loss from the first base station is not larger than the path-loss threshold, and continuing operating on the carrier frequency on which the restricted access cell is deployed when the measured path-loss is not larger than the path-loss threshold.
4. The method according to claim 1, determine the measured path-loss based on a signal from a base station, wherein the base station and the restricted access cell share the carrier frequency.
5. The method according to claim 1 further comprising receiving from the restricted access cell an indication that intra-frequency reselection is not allowed, barring the carrier frequency on which the restricted access cell is deployed when all of the following conditions are satisfied: the measured path-loss is larger than the path-loss threshold, the mobile station is not allowed access to the restricted access cell, and an indication that intra-frequency reselection is not allowed is received.
6. The method according to claim 1 further comprising receiving from the restricted access cell an indication that intra-frequency reselection is allowed, and operating on the carrier frequency on which the restricted access cell is deployed when any one of the following conditions is satisfied: the measured path-loss is not larger than the path-loss threshold, the mobile station is allowed access to the restricted access cell, an indication that intra-frequency reselection is allowed is received.
7. The method according to claim 1, determine the measured path-loss, wherein the measured path-loss is a transmit power of a base station signal minus a received power of the base station signal.
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
10. The method according to claim 9, further comprising determining that the wireless communication device is not required to reselect 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 less than the path-loss threshold
11. The method according to claim 9 receiving from the restricted access cell an indication of whether intra-frequency reselection is allowed; and determining that the wireless communication device is required to reselect 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, that the measured path- loss from the serving base station is equal to or greater than the path- loss threshold, and receiving an indication from the restricted access cell that intra-frequency reselection is not allowed
12. The method according to claim 9 determining that the wireless communication device is not required to reselect 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, and receiving an indication from the restricted access cell that intra- frequency reselection is allowed.']
