  • Patent number: 5765103
    Abstract: While setting up a fixed wireless system, each subscriber radiotelephone is configured to a permanent home cell. Subscribers located at the border of a cell may be configured to multiple cells for better coverage. The signal levels at the border subscriber's position are received and the mean values of each determined. These mean values are listed in descending order. If the largest mean value is greater than a predetermined threshold, the subscriber is configured to only the home cell. If the largest mean value is within a predetermined range, the second largest mean value is evaluated to determine if it is within the predetermined range. If so, the subscriber is configured to both serving cells. If the second largest mean value is outside the predetermined range, the subscriber is configured to only the home cell.

  • Patent number: 5668862
    Abstract: A method of providing call screening to a subscriber of personal communication services facilitates the screening of incoming calls by associating the number dialed by a calling party with a function or role of the dialed number. This function or role is then sent to the subscriber when an incoming call is received. This way, the subscriber can decide whether to answer the incoming call based upon knowing the role or context associated with the dialed number. The subscriber is also provided with user controlled features which can be invoked by the use of DTMF codes. The subscriber can place a calling party on hold prior to answering the incoming call. In addition, the subscriber can proceed with a call transfer from a wireless telephone to a wired telephone and vice-versa, while the call is still in progress. Another feature allows the subscriber to implement a real-time call screening, while the calling party is leaving a message on voice mail.
