  • Patent number: 8150344
    Abstract: A method and system are provided for planning a service provider network. At one or more low-cost Internet base stations (LCIBs) operating within a building, one or more wireless signals are detected. The wireless signals are provided by one or more macro base stations. The wireless signals are detected by the LCIB on an LCIB wireless-communication interface. For each detected wireless signal, one or more signal-strength values are determined. The determined signal-strength values are sent from the LCIB via an LCIB packet-communication interface to one or more network entities. The signal-strength values are used to plan the service provider network, by generating one or more network-planning directions and/or one or more network-coverage maps.

  • Patent number: 7742453
    Abstract: Disclosed herein is a method to condition removal of a carrier frequency from a wireless coverage area. The method involves evaluating handoff statistics for the coverage area, and applying results of past carrier frequency removal (preferably from a morphologically similar cluster) to predict a net change in hard handoffs that will result if the carrier frequency is removed. The method then involves using the predicted net change in hard handoffs as a basis to determine whether to remove the carrier frequency. The predicted net change in hard handoffs may be converted to a corresponding predicted net change in call drops, and the carrier frequency may then be removed only if the predicted net change in call drops does not exceed a threshold.

  • Patent number: 7697489
    Abstract: A network access server, such as a PDSN, might provide Mobile IP services to one or more access points for a wireless wide area network. A wireless device might handoff to an access point served by the network access server, and the wireless device might receive from the access point an identifier, such as a Packet Zone ID, that identifies the network access server. The wireless device might then register with the access server but delay making any subsequent Mobile IP re-registrations until after a predetermined amount of time.
