PROBLEM TO BE SOLVED: To provide a method for access control in a femto cell.SOLUTION: The method comprises: assigning at least one femto cell to correspond to a first identifier that identifies valid access to the femto cell; storing a list comprising at least one second identifier and at least one first identifier (where a second identifier corresponds to an AT and the list indicates valid first identifier and second identifier pairs); receiving, at a femto cell, a request from an AT for access (1030); sending, by the femto cell, the first identifier to at least one access control component (1035); determining, from the list, whether a second identifier for the AT corresponds to a valid first identifier for the femto cell (1040); and granting access to the AT at the femto cell in response to the request if the AT is identified.
Abstract:
PROBLEM TO BE SOLVED: To facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection.SOLUTION: In measuring and ranking surrounding access points in reselection, offsets are applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements of some access points. Hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected on the basis of a type of the current cell or related access point to expand the coverage area where desired.

PROBLEM TO BE SOLVED: To provide a mobile station that is configured to facilitate coordination of supplementary services in a centralized fashion.SOLUTION: A mobile station may include: circuit-switched (CS) domain components that are configured to place voice telephone calls in a CS domain; and IP multimedia subsystem (IMS) components that are configured to place voice telephone calls in an IMS domain. The IMS components may include a transport component for facilitating communication with an IMS core network. The IMS components may also include a signaling component that is configured to exchange information with a centralized server on the IMS core network via the transport component. At least some of the information that is exchanged with the centralized server may be related to supplementary services for the voice telephone calls in the CS domain as well as the voice telephone calls in the IMS domain.

PROBLEM TO BE SOLVED: To provide a method of selecting a sleep interval in a mobile communication device.SOLUTION: A mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network negotiates, while communicating over the packet-switched network, a sleep interval that is longer than the ordinary sleep interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conserves power. A buffering system is included so that data directed towards the device while the device is asleep is delivered later when the device awakens.
Abstract:
PROBLEM TO BE SOLVED: To provide systems and methods that facilitate device-side access point list management.SOLUTION: Blacklists of access points unsuitable for providing network access to a related mobile device can be maintained as well as whitelists of suitable access points for doing so can be maintained. The lists can be managed using an interface provided at the mobile device. In addition, the lists can be modified according to provisioned network updates. Also, the lists can be of maximum size such that older entries can be purged upon insertion of newer entries on the basis of a number of factors. Timed entry deletion is provided as well. Access points in the lists can be stored and presented according to various identifiers related to the access points.

Abstract:
PROBLEM TO BE SOLVED: To improve the standby time of a station in a wireless network.SOLUTION: An access point advertises or conveys a maximum listen interval and/or an association timeout supported by that access point. A station operates in a power-save mode and wakes up every listen interval to receive a beacon and any potential traffic for the station. The station selects a suitable listen interval on the basis of the maximum listen interval. The station is dormant for a longer duration than the listen interval and becomes active at least once in every association timeout in order to keep the association with the access point alive.
Abstract:
PROBLEM TO BE SOLVED: To provide an access terminal, and method for selecting an access point for handing off the access terminal.SOLUTION: The access terminal may include a processor. The processor may be configured to access a list access points and select one of the access points on the list based on the current traffic state of the access terminal.
