Abstract: Communication diversity using a plurality of satellites is disclosed. The satellites can support multiple regions corresponding to multiple satellite beams. Each satellite can support all regions in the reverse direction and each satellite can be designated as a primary satellite for one of the multiple regions corresponding to one of the multiple satellite beams. Each satellite can receive from any of the regions reverse link signals broadcast by, for example, a mobile station. Each satellite can communicate the received reverse link signals to, for example, a base station or gateway where the signals can be combined to increase signal quality. A mobile station receives forward link signals from the primary satellite and monitors a signal quality from the primary satellite and from a secondary satellite. If the signal quality from the primary satellite drops below a threshold value, the communication signal is transferred to the secondary satellite.

Abstract: Improvement of wireless communications of a wireless device may include storing a preferred roaming list containing information associated with communications carriers arranged in a predetermined order. It may be determined that a signal strength of a first communications signal of a first communications carrier currently being received by a wireless device drops below a signal strength threshold value. A second communications carrier in the preferred roaming list having a second communications signal with a higher signal strength than the signal strength of the first communications signal may be selected. A time interval over which to receive the second communications signal from the second communications carrier may be initiated and a switch may occur from receiving the second communications signal from the second communications carrier to receiving a third communications signal from a communications carrier in the preferred roaming list in response to completion of the time interval.

Abstract: Systems and methods are provided to establish a set of dynamic channel masks that select channels to be scanned in a wireless environment during a mobile terminal roaming. The set of channel masks is associated with a set of scan groups determined through a Boolean operation applied to a set of scan variables determined via data indicators that reflect channel quality and/or presence in the vicinity of the mobile terminal. Regardless of actual access point geometric configuration in a quasi-two-dimensional coverage plan, a universal set of three scan groups can be determined. In addition to the universal set, a fail-safe set is computed in order to ensure successful scanning in various roaming scenarios. Quality of service indicators like communication reliability and battery performance can be improved by successively scanning the universal scan groups during roaming.

Abstract: In a cellular phone, when a coming-to-the-office signal is detected by a non-contact IC section, a CPU selects an official mode as a telephone number mode. Meanwhile, when a leaving-the-office signal is detected by the non-contact IC section, the CPU selects a private mode as a telephone number mode. In an application menu, applications usable and not usable in the current telephone number mode are displayed according to the availability mode added for the applications so that a user can identify these applications. Only the files corresponding with the current telephone number mode can be selected according to the mode identifier added for the file, or the type of the folder storing the file. Thereby, a plurality of processing functions included in the cellular phone, or many files stored therein can be automatically used selectively either on official use or on private use.

Abstract: In some embodiments, an automobile has a station that can support a portable electronic device (PED). The station includes a body, which could be integrated with the automobile. The body defines a PED seat, for supporting the PED. A movable member can exert tension so as to bias the supported PED, to prevent the PED from falling off. Detection means can detect when the PED is receiving a wireless signal. A human-perceptible indication can be generated in response to the detection means, above and beyond any ringing and/or vibrating from the PED itself. As such, a user can always keep the PED at the “Silent” annunciation mode even while in the automobile.

Abstract: Generally, the present invention provides accessories for one or more portable electronic devices (PEDs) and related methods. An accessory includes a station that can support a PED. The PED is also equipped to generate an action signal, above and beyond the regular signal for notifying the user about a wireless signal that is received from a remote transmitter. When the station senses the action signal, it further generates a human-perceptible indication to help notify the user, who might have walked away. The human-perceptible indication can include, a call sound, a light signal, etc. This way, for example, when the PED is only vibrating, the call sound can be such that the station rings like a regular home telephone, and/or the light signal can be such that the station lights up without distracting coworkers as much. As such, the user can always keep the PED at the “Silent” annunciation mode.
