  • Patent number: 8619674
    Abstract: A radio access network (RAN) includes a first wireless access point that radiates to define a first wireless coverage area, and a second wireless access point that radiates to define a second wireless coverage area. A dual-mode wireless communication device (WCD), capable of communicating via both the first and second wireless coverage areas registers with the first wireless access point. As part of the registration process, or at some point thereafter, the first wireless access point transmits information that identifies the second wireless coverage area. The first wireless access point also transmits a WCD identifier received from the WCD during the registration process to the second access point, so that the second access point can add the WCD identifier to its whitelist. Thus, via the second wireless coverage area, the WCD can register with the second wireless coverage area.

  • Patent number: 8504021
    Abstract: A wireless communication device is disclosed for scanning a preferred roaming list (PRL) in a non-roaming mode. The wireless communication device exchanges wireless communications with a first wireless communication network and monitors communication performance of the first wireless communication network while operating in a non-roaming mode. The wireless communication device processes the PRL to perform scans for a pilot signal from a second wireless communication network while operating in the non-roaming mode. The wireless communication device subsequently performs a time correlation of the communication performance of the first wireless communication network and the scans for the pilot signal of the second wireless communication network to determine that a roaming mode should be entered. The roaming mode is then entered and the wireless communication device exchanges wireless communications with the second wireless communication network while operating in the roaming mode.

  • Patent number: 8472876
    Abstract: Methods and systems are provided for determining the absence of a personal area network (PAN) device and for responsively presenting the time of the last detected presence of the PAN device. In an exemplary embodiment, a PAN device encounters a triggering event and responsively checks and determines that another PAN device is absent. Upon detecting the absence of the other PAN device (such as by detecting an absence of communication from the other PAN device), the exemplary PAN device presents via a user interface an indication of the time that it last detected presence of the other PAN device. By presenting the time of the last detected presence of the other PAN device, the user of the PAN device may be able to recall where he or she was at that time, which may help the user find the misplaced PAN device, hopefully at that location.
