Abstract
Systems and methods for reducing interference and saving power for home Node Bs are disclosed. Home Node Bs can be configured to remain in sleep mode until needed based on various criteria, periodically operating transmit and receive components in order to detect mobile devices that may need the services of the home Node B. Mobile devices can indicate one or several target home Node Bs using one or more node identifiers within a proximity indication message. Closed subscriber group identifiers and membership data may also be included in a proximity indication message. Node or cell identities, along with membership data, may be stored in a fingerprint database or white-list on a mobile device.

21. A method performed by a radio network controller of a first radio access technology (RAT) for operating an eNodeB of a second RAT, the method comprising:
-
determining to initiate a first activation of a first eNodeB of the second RAT in a dormant state, the first activation being limited to a duration of a predetermined time interval, the first eNode B of the second RAT serving an area covered by the radio network controller of the first RAT; sending to the first eNodeB of the second RAT a first instruction for the first activation, the first instruction causing the first eNodeB of the second RAT to activate for the predetermined time interval; determining to initiate a second activation of the first eNode B of the second RAT to increase inter-RAT cellular communication capacity, the second activation of the first eNodeB of the second RAT not being limited by the predetermined time interval; and sending to the first eNodeB of the second RAT a second instruction for the second activation, the second instruction causing the first eNodeB of the second RAT to activate. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A radio network controller of a first radio access technology (RAT), comprising:
-
a memory; a processor, the processor configured to; determine to initiate a first activation of a first eNodeB of a second RAT in a dormant state, the first activation being limited to a duration of a predetermined time interval, the first eNode B of the second RAT serving an area covered by the radio network controller of the first RAT; and a transceiver, the transceiver configured to; send to the first eNodeB of the second RAT a first instruction for the first activation, the first instruction causing the first eNodeB of the second RAT to activate for the predetermined time interval, the processor being further configured to; determine to initiate a second activation of the first eNode B of the second RAT to increase inter-RAT cellular communication capacity, the second activation of the first eNodeB of the second RAT not being limited by the predetermined time interval, the transceiver being further configured to; send to the first eNodeB of the second RAT a second instruction for the second activation, the second instruction causing the first eNodeB of the second RAT to activate. - View Dependent Claims (30, 31, 32, 33, 34, 35)
