Abstract
A method and apparatus of selecting a cell in a wireless communication system is provided. A user equipment receives an Intra Frequency Reselection indicator (IFRI) from a barred cell. The user equipment starts an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell and searches neighboring cells in the frequency of the barred cell while the IFR timer is running.

Claim
1. A method of selecting a cell in a wireless communication system, the method comprising:
receiving, by a user equipment, an Intra Frequency Reselection indicator (IFRI) from a barred cell;
starting, by the user equipment, an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell; and
searching, by the user equipment, neighboring cells in the frequency of the barred cell while the IFR timer is running.', 'receiving, by a user equipment, an Intra Frequency Reselection indicator (IFRI) from a barred cell;', 'starting, by the user equipment, an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell; and', 'searching, by the user equipment, neighboring cells in the frequency of the barred cell while the IFR timer is running.
2. The method of claim 1, further comprising:
searching, by the user equipment, neighboring cells in a frequency different than the frequency of the barred cell when the IFR timer expires and stopping to search the neighboring cells in the frequency of the barred cell.', 'searching, by the user equipment, neighboring cells in a frequency different than the frequency of the barred cell when the IFR timer expires and stopping to search the neighboring cells in the frequency of the barred cell.
3. The method of claim 2, further comprising:
stopping, by the user equipment, the IFR timer when a new cell is selected while the IFR timer is running.', 'stopping, by the user equipment, the IFR timer when a new cell is selected while the IFR timer is running.
4. The method of claim 1, wherein the barred cell is a cell which is barred to the user equipment or is treated as barred by the user equipment.
5. The method of claim 1, wherein the barred cell is a Closed Subscriber Group (CSG) cell.
6. The method of claim 1, wherein the IFRI is received as a part of system information for the barred cell.
7. A wireless apparatus of selecting a cell in a wireless communication system, the wireless apparatus comprising:
a radio frequency (RF) unit for transmitting and receiving a radio signal; and
a processor operatively coupled with the RF unit and configured to:
acquire an Intra Frequency Reselection indicator (IFRI) from a barred cell;
start an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell; and
search neighboring cells in the frequency of the barred cell while the IFR timer is running.', 'a radio frequency (RF) unit for transmitting and receiving a radio signal; and', 'a processor operatively coupled with the RF unit and configured to:
acquire an Intra Frequency Reselection indicator (IFRI) from a barred cell;
start an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell; and
search neighboring cells in the frequency of the barred cell while the IFR timer is running.', 'acquire an Intra Frequency Reselection indicator (IFRI) from a barred cell;', 'start an Intra Frequency Reselection (IFR) timer when the IFRI indicates not to allow reselection of a neighboring cell in a frequency of the barred cell; and', 'search neighboring cells in the frequency of the barred cell while the IFR timer is running.
8. The wireless apparatus of claim 7, wherein the processor is configure to:
when the IFR timer expires, search neighboring cells in a frequency different to the frequency of the barred cell and stop to search the neighboring cells in the frequency of the barred cell.', 'when the IFR timer expires, search neighboring cells in a frequency different to the frequency of the barred cell and stop to search the neighboring cells in the frequency of the barred cell.
9. The wireless apparatus of claim 8, wherein the processor is further configured to stop the IFR time when a new cell is selected while the IFR timer is running
10. The wireless apparatus of claim 7, wherein the barred cell is a cell which is barred to the wireless apparatus or is treated as barred by the wireless apparatus
11. The wireless apparatus of claim 7, wherein the barred cell is a Closed Subscriber Group (CSG) cell
12. The wireless apparatus of claim 7, wherein the processor is further configured to acquire the IFRI as a part of system information for the barred cell.']
