If the last frequency used does not have a more preferred service provider, the device examines each of the plurality of frequencies in the predetermined order in the search schedule. The examination continues until another frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.

Abstract: In a mobile terminal communication method, when a zone in which a mobile terminal is positioned becomes in a congestion state, a calling channel having high emergency can be secured. A connection priority rank is given to each mobile terminal. When an area in which a calling mobile terminal is positioned is in the congestion state, the number of currently-used calling channels in the same connection priority rank as that of the mobile terminal is compared with the number of the calling channels set to the rank. Depending on its result, the call is disconnected or another mobile terminal in a low connection priority rank is handed off to another area.

Abstract: Power consumption in outside the area is suppressed by reducing band search processing time thereby to reduce the time required from the power-on to the completion of acceptance. Frequencies adjacent each other in their ascending order in a predetermined frequency band are divided into groups. The number of frequencies in each of the groups is smaller than the number of frequencies constituting the predetermined frequency band. The number not more than the number of frequencies constituting each group and not less than one, e.g., a single frequency, is set as a representative frequency. It is decided whether the representative frequency satisfies a first condition on the basis of a received signal strength indicator (S11). From all the frequencies in the group to which the representative frequency satisfying the first condition belongs, there are selected frequencies that satisfy a second condition on the basis of the received signal strength indicator (S14).

An integrating filter is coupled to receive the output signal from the absolute value detector and supply an integrated signal. The integrating filter has at least one selectable filter coefficient indicative of the response time of the integrating filter.

Abstract: A method and apparatus for selecting radio stations for reception based on a preferred program content. A list of radio station identifiers is stored in a memory and organized according to program content specifiers. When a presently received signal fades, the memory is searched for an alternate radio station with similar program content. If none is available, a prioritized list of alternative program content preferences is accessed and used to index other preferred radio stations for searching. In one embodiment, radio station geographic location information is stored in the memory, and the searching operation considers both program content preference and geographic proximity. The memory can be manually programmed, pre-programmed, updated by subscription, or programmed over-the-air by radio transmission. In one embodiment, a global positioning system receiver is employed to provide instantaneous radio location information.
