Abstract: A mobile station can be authenticated by, for example, sending a challenge to a mobile station, and receiving a first authentication response from the mobile station through a wireless link, the first authentication response being generated based on the challenge and an authentication key stored at the mobile station. A second authentication response is generated based on the first authentication response. The second authentication response is provided to an IMS network for authenticating the mobile station to enable the mobile station to access the IMS network. In some examples, an authentication response of the mobile station is carried in an SIP message sent from the femtocell to a server that can authenticate the mobile station or forward the authentication response to another server that can authenticate the mobile station. Authentication of the mobile station can be performed as an integrated part of or separate from a registration process.

Abstract: In general, media data is stored in a storage medium of a mobile base station. The mobile base station transmits the media data from the mobile base station to a handheld device through a packet data protocol context.

Abstract: Among other things, a system for use in wireless communication includes a first device communicating via a first protocol in a first network, a cellular device communicating via a second protocol in a cellular network, the second protocol being incompatible with the first protocol, and an access point in the cellular network, the access point being accessible by the cellular device and being configured to enable communication between the first device and the cellular device.

Abstract: A system is used in a wireless communication system made up of cells, at least one of which includes at least one sector. The system includes first access points in a first area of a sector of a cell. The first access points are prohibited from communicating over a first frequency. The system also includes second access points in a second area of the sector of the cell. The second access points are prohibited from communicating over a second frequency that is different from the first frequency.

Abstract: A home base station receives signal to interference and noise ratio data from at least one access terminal, determines whether a transmission power of the home base station should be adjusted based on the received signal to interference and noise ratio data, and then adaptively adjusts the transmission power of the home base station based on the received signal to interference and noise ratio data.

Abstract: The invention relates to a method and system of setting transmitter power levels, particularly in a Local Network Node transmitter, providing a pico cell for private use. A User Equipment (UE) is used to make measurements of the transmission link properties, such as downlink power and round trip time. Based on the measurements made at one or a plurality of locations, the power of the Local Network Node can be determined such that interference is minimized with any overlying cells of a macro-network. Call handovers between the UE and the cell of a macro network can also be arranged based on properties measure by the UE.

Abstract: A method for configuring a network is described, the method comprising: receiving, from a first radio node in the network, network information associated with one or more second radio nodes in the network; generating a network relation table, the network relation table comprising network information associated with the first radio node and the one or more second radio nodes; and performing a handoff to a third radio node in the network using the network relation table.

Abstract: In general, a method performed on a portable access terminal operating in an active mode includes detecting a presence of a personal base station. An encoded identification message transmitted from the personal base station is received, and the encoded identification message includes a unique identifier associated with the personal base station. The encoded identification message is decoded to extract the unique identifier, and the unique identifier is transmitted to a source network entity.

Abstract: An invitation to use a personal access point to access a wireless network is transmitted to an access terminal. An indication that the invitation has been accepted is received and the personal access point is authorized to provide the access terminal with access to the network. At an access terminal, an invitation to use a personal access point to access a wireless network is received, an instruction to accept the invitation is received from an operator of the access terminal, and an acceptance of the invitation is communicated.

Abstract: This description relates to access terminal hand-off methods in wireless networks.

Abstract: A method includes modifying at least one communications protocol packet being passed between at least one of a plurality of portable base stations and a core network, such that the core network considers the plurality of portable base stations as a single base station.

Abstract: In addition to other aspects disclosed, a portable base station requests assignment of a portion of a code space from a remotely located control station. The assignment is based upon the location of the portable base station. The portable base station is also capable of transmitting an identification signal using the assigned code space portion to uniquely identify the portable base station to one or more access terminals.

Abstract: Among other things, a method performed by a first access point is described. The method includes outputting signals. At least some of the signals interfere with communication between a device and a second access point. The method also includes determining whether to output the signals in a predefined mode based on dynamically calculated values of a parameter. The parameter is related to signal interference at the device. If it is determined to output the signals in the predefined mode, for a time period, the first access point outputs signals in the predefined mode.

Abstract: An access point detects a presence of a first device having a device identifier in a femtozone associated with the access point. The access point matches the device identifier with a first personal policy server identifier associated with a corresponding first personal policy profile comprising a first set of rules and retrieves the first personal policy profile corresponding to the first personal policy server identifier. The access point applies the first set of rules in the first personal policy profile.

Abstract: In general, in one aspect, instructions are received from a user for management of a network device, the instructions are adjusted for compatibility with requirements of a network provider other than the user, and the adjusted instructions are implemented on the network device.
