Abstract

A method and apparatus of establishing a connection in a wireless communication system is provided. A user equipment (UE) receives first barring information for member UEs and second barring information for non-member UEs, determines whether the UE is able to access to a cell or not based on one of the first barring information and the second barring information according to whether the UE is either a member UE or a non-member UE, and transmits an access request if it is determined that the UE is able to access to the cell.

Claims

1. A method of establishing, by a user equipment (UE), a connection in a wireless communication system, the method comprising:

receiving first barring information for member UEs and second barring information for non-member UEs;

determining whether the UE is able to access to a cell or not based on one of the first barring information and the second barring information according to whether the UE is either a member UE or a non-member UE; and

transmitting an access request if it is determined that the UE is able to access to the cell.

2. The method of claim 1, wherein the member UEs are members of a specific closed subscriber group (CSG), and

wherein the non-member UEs are not members of the specific CSG.

3. The method of claim 1, wherein the cell is a hybrid cell.

4. The method of claim 1, wherein the first barring information and the second barring information are received via system information.

5. The method of claim 1, wherein the first barring information and the second barring information are received via a system information block type 2 (SIB2).

6. The method of claim 1, wherein the first barring information and the second barring information include different sets of equivalent parameters respectively.

7. The method of claim 6, wherein each set of equivalent parameters includes barring factor and barring time.

8. The method of claim 1, wherein whether the UE is able to access to the cell or not is determined based on the first barring information if the UE is a member of a specific CSG.

9. The method of claim 1, wherein whether the UE is able to access to the cell or not is determined based on the second barring information if the UE is not a member of a specific CSG.

10. The method of claim 1, wherein whether the UE is able to access to the cell or not is determined when a radio resource control (RRC) connection establishment is initiated.

11. The method of claim 1, wherein the access request is an RRC connection request.

12. The method of claim 1, wherein the access request includes a CSG membership status of the UE.

13. A user equipment (UE) in a wireless communication system, the UE comprising:

a radio frequency (RF) unit for transmitting or receiving a radio signal; and

a processor coupled to the RF unit and configured for;

receiving first barring information for member UEs and second barring information for non-member UEs;

determining whether the UE is able to access to a cell or not based on one of the first barring information and the second barring information according to whether the UE is either a member UE or a non-member UE; and

transmitting an access request if it is determined that the UE is able to access to the cell.

14. The UE of claim 13, wherein the member UEs are members of a specific closed subscriber group (CSG), and

wherein the non-member UEs are not members of the specific CSG.

15. The UE of claim 13, wherein the cell is a hybrid cell.
