  • Patent number: 5822686
    Abstract: Methods and systems for measuring signal strengths of radio signals in radiocommunication systems are described. In many radiocommunication systems, base stations and/or mobile station take signal strength measurements on various radio channels, e.g., those in neighboring calls, to provide information to the system for channel allocation and handoff decisions. By sorting lists of channels to be measured into frequency order and taking into account a last tuned channel as well as radio specific tuning characteristics, the overall time spent tuning to each channel in the list can be reduced.
