Abstract: A method for providing a neighborhood or local cordless service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roams from one zone to another, the subscriber may continue their free call uninterrupted and without paying air time charges. However, when the subscriber roams outside their subscribed-to zones they may be switched from the present neighborhood or local cordless services to conventional personal communications services and pay air time charges. However for an active call, no air-time charges are incurred as the user transitions between the cellular/DPCS environment and the neighborhood or local cordless service environment.

The permanent ID identifies a second activation frequency for a subsequent activation of the cordless telephones (12,14).

Abstract: A method for servicing data communications in a cellular wireless communication system supports data communications on fundamental channels (FCHs) and supplemental channels (SCHs). The method includes first determining an operational relationship between a burst duration and a burst delay of the SCHs and Transmission Control Protocol (TCP) layer throughput provided by the cellular wireless communication system. The operational relationship relates TCP layer throughput as a function of the burst duration and burst delay of the SCHs. Then, the method includes servicing, by a base station of the cellular wireless communication system, data communications for a plurality of wireless terminals using a plurality of FCHs and at least one SCH. In servicing the data communications, the burst duration and the burst delay of the at least one SCH are managed in an attempt to provide a minimal TCP layer throughput degradation for at least some of the plurality of wireless terminals.

Abstract: Clocks between at least two wireless devices are synchronized to reduce the need to transmit synchronization signals over a wireless communication channel therebetween. Two wireless devices synchronize their respective clocks with each other when each are electrically coupled, e.g., during a cradle time when brought into physical contact with each other through charge contacts, e.g., to recharge a remote portable unit. The charge signal appearing at the charge contacts is driven to create a time duration marked by a start transition and an end transition in the charge signal. The number of clock pulses of each of the two wireless devices during the time duration is counted, and compared to determine the difference in clock speeds of the wireless devices. The frequency of the clock of at least one of the wireless devices is adjusted to bring the difference in the clock speeds within a predetermined threshold tolerance level.

Abstract: When a main device 1 detects an incoming message, the main device 1 transmits a call frame to auxiliary devices 2, 3 during a first time slot of a first cycle. In succession with this, the auxiliary-device 2 transmits a ready frame in a slot 2 to notify main devices of other systems that the communication channel is being used. Neither of the auxiliary devices 2, 3 respond in the third time slot. The same transmission and reception processes are performed in the second cycle. However, afterward in the third cycle, the auxiliary device 2 is brought into an off-hook condition and so transmits an off-hook frame during the third time slot of the third cycle. The main device 1 receives the off-hook frame and transmits a connect frame in the first time slot of the fourth cycle to the auxiliary device 2. In response, the auxiliary device 2 starts communication.

However, when the subscriber roams outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges. However for an active call, no air-time charges are incurred as the user transitions between the cellular/DPCS environment and the local cordless service environment.

Abstract: The present invention is a system of at least one cordless telephone, a home base station and at least one non-home base station. A roaming cordless telephone out of range of its home base station will use a non-home base station to direct digital mode signals to its home base station. The home base station will convert the digital mode signals to analog signals and communicate them with the telephone network. Only a single direct line connection is needed for the home base station, as the digital mode signals and the analog signals communications do not interfere with each other. The user may potentially avoid long distance charges by using the non-home base station as a conduit while using the home base station as the telephone network site for long distance charge accrual. Further, the necessity for using a cellular telephone with the consequent charges is avoided.
