Methods for access control in femto systems
First Claim
1. A method for controlling access to wireless resources provided by femto cells within a femto subnet of a radio access network, the method comprising:
- establishing, by the radio access network, a hashing channel mask of a first-type and hashing class mask of the first-type for each first femto cell within the femto subnet, each hashing class mask of the first-type providing access to at least one corresponding first femto cell within the femto subnet, the hashing channel mask of the first-type indicating channels used for communication within the femto subnet; and
assigning a hashing class mask of the first-type or a hashing class mask of a second-type to a wireless user based on whether the wireless user is authorized to access a first femto cell within the femto subnet, the hashing class mask of the first-type being associated with at least one femto cell and the hashing class mask of the first-type indicating a priority class of the wireless user, and the hashing class mask of the second-type being associated with at least one femto cell and the hashing class mask of the second-type indicating a priority class of the wireless user.

Abstract
In a method for controlling access to wireless resources provided by femto cells within a femto subnet a femto management system or radio access network may control access to femto cells within the femto subnet by assigning at least one hashing class mask of a first-type or hashing class mask of a second-type to a wireless user. The hashing class mask of the first-type or hashing of the second-type class mask may be assigned based on whether the wireless user is authorized to access a first femto cell within the femto subnet. The hashing class mask of the first-type provides access to at least one first femto cell within the femto subnet.

13. A method for controlling access to wireless resources within a femto cell of a radio access network, the method comprising:
-
establishing, by the radio access network, a hashing mask pair of a first-type for a first femto cell, the hashing mask pair of the first-type including a hashing channel mask of the first-type and corresponding hashing class mask of the first-type; providing, by the radio access network, a hashing channel mask of a second-type for the first femto cell; storing, within the radio access network, the hashing mask pair of the first-type and the channel hashing mask of the second-type in association with identification information for the femto cell; and assigning one of the class hashing mask of the first-type and a class hashing mask of the second-type to a wireless user. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for restricting access to a first femto cell in a femto subnet, the method comprising:
-
determining whether a wireless user authorized to access the first femto cell is present in the femto subnet; and restricting access to the first femto cell by assigning a null hashing channel mask to the first femto cell.

20. A method controlling access to wireless resources within a radio access network, the method comprising:
-
establishing, by the radio access network, a hashing channel mask of a first-type and hashing class mask of the first-type for each first femto cell within each femto subnet of a femto system, each hashing class mask of the first-type providing access to at least one corresponding first femto cell; assigning a plurality of the hashing class masks to a wireless user, each of the plurality of hashing class masks being associated with a femto subnet within a femto system; storing the assigned hashing class masks in association with corresponding femto subnet identifiers; and sending the assigned hashing class masks and corresponding femto subnet identifiers to the wireless user. - View Dependent Claims (21, 22)
