Abstract: Disclosed herein are an apparatus for providing handover information within a femtocell network, and a terminal using the same. The apparatus includes an expected stay time calculation unit, a handover target selection unit, and a handover information provision unit. The expected stay time calculation unit, for a terminal located within serving coverage range of a serving base station, calculates expected stay time, that is, a time for which the terminal will stay within a femtocell coverage range of each of the femtocell base stations. The handover target selection unit selects a handover target from among the femtocell base stations based on the calculated expected stay time. The handover information provision unit provides the terminal with handover information including the selected handover target.

Abstract: A mobile device, system, and method are directed towards employing a social SMS question and response interaction to identify and provide an advertisement to questioner, along with the response. In one embodiment, the questioner may register for discounts to the SMS server in return for receiving advertisements. As the questioner sends a question to another user, the question may be intercepted and a copy stored. When the other user provides a response to the question, the response may be intercepted and used to socially refine the question. The refined question may then be used to select a contextual advertisement sent with the response. In one embodiment, the questioner may receive a discount for receiving the contextual advertisement.

Abstract: A wireless communication system comprising first and second transceivers. The first transceiver communicate with a base station, wherein the base station communicates with the first transceiver and a plurality of other wireless communication devices according to a wide area wireless communication protocol. The second transceiver is coupled to the first transceiver and communicates with a first mobile station, wherein the second transceiver communicates with the first mobile station according to a local area wireless communication protocol. The first transceiver receives from the base station a first downlink signal intended for the first mobile station and transmits the first downlink signal to the second transceiver. The second transceiver re-transmits the first downlink signal to the first mobile station as a second downlink signal according to the local area wireless communication protocol.

Abstract: Multi-mode communication devices capable of wLAN and WAN wireless network communication modes and/or wired modes can be configured to communicate for backend services (e.g. Web Services, database, events) via a network gateway to operate in response to available modes. For example, for some activities (e.g. notification messages), the devices may be configured to communication in any available mode (WAN or wLAN) while for other activities (e.g. high bandwidth communications), the devices may be restricted to one mode only (e.g. wLAN). Component applications for execution by the devices can specify message delivery properties to indicate the mode(s) to may used for a particular message. Runtime mode information may be provided and maintained automatically by a communications subsystem interface for determining mode availability. A programming tool and gateway are also described.

The device uses a cell database to route the emergency call to the PSAP, based on the cell ID, when the UE is a wireless device.

Finally, a signal propagation model for the indoor environment is created based on the signal propagation characteristic and the signal samples, and a distance to any wireless access point in the indoor environment is estimated based on the signal propagation model.
