Abstract: A method and apparatus to perform a real-time drift correction of a remote handset's local oscillator in a digital cordless telephone. The remote handset begins in a standby (sniff) mode. The remote handset periodically wakes from a sleep mode and goes into a normal link verification mode. Once in the link verification mode, the remote handset enters a time division duplexing (TDD) mode and attempts to establish a link with a base unit based on the timing of the TDD data frame. After the remote handset establishes a link with the base unit, the remote handset requests a security word from the base unit. Upon receiving the requested security word, the remote handset determines if the requested security word matches a security word of the remote handset. The remote handset implements a software frequency adjustment of its local oscillator. Once per frame, the remote handset enters a timing recovery state where the current state of the frame is compared with a previous state.

Abstract: In a communication system which has a base station, a mobile station and an object device controllable by the mobile station, the mobile station monitors status of the object device to detect whether or not the object device is ready to receive a data signal sequence sent through the mobile station. Such a data signal sequence may be either a voice data signal or an image data signal. The mobile station can transmit, towards the base station, a response determined by the status of the object device. A reception state of the object device may be switched from one to another to selectively receive the voice and the image data signals.

Abstract: A cellular based universal telephone system adapted for both cellular and land line service uses cellular service for both out-of-home mobile communications, and mimics land line service inside of homes by connecting one or more cellular handsets to a converter unit, which converter unit is connected to the home telephone wiring. Several off-the-shelf, non-cellular handsets can be connected to the telephone wiring (and hence to the converter unit), for answering and placing telephone calls involving the cellular telephone number. The converter unit contains a mobile converter unit and a land line interface unit. The mobile converter unit converts cellular signals from the cellular handset(s) into land line signals understandable by or needed by the non-cellular handsets, such as ringing signals, message waiting signals and call waiting tones.

Abstract: A cordless telephone system comprising a handset and a base station. Each of the handset and the base station contains a transmitter and a receiver, preferably operating on different frequencies. At least one of the handset and the base station controls frequency hopping based on a signal received from the other of the handset and the base station. In a preferred embodiment, The handset transmitter transmits to the base station a combined signal including a digital portion and an analog portion.

Abstract: The present invention provides a system and method for using a standard private branch exchange (PBX), such as e.g., the Lucent Technologies, Inc. DEFINITY® PBX, for interfacing with a wireless (e.g., cellular, etc.) communication network and the public switched telephone network (PSTN). The system employs an adjunct controller and uses computer telephony integration (CTI) associated with a standard PBX to communicate directly with an audio switch and the PSTN. Through the use of CTI, the standard PBX also provides feedback to the caller. For example, when an inbound call arrives (i.e., from the PSTN to a radio transceiver), the adjunct controller determines whether the wireless system has available resources (i.e., an available link) to grant calls and instructs the PBX to provide an audio connection between dynamically assigned wireless links (e.g., RF channels). If no link is available, a busy signal is referred back to the PSTN, and eventually back to the originating switch.

Abstract: A method allows a user of a mobile terminal to switch from a communication service currently active between that mobile terminal and another mobile terminal to a different communication service in such a manner that the end to end connection between terminals appears unbroken to the user. The user initiates the switch by inputting an appropriate command at the mobile terminal. The mobile terminal then transfers a request to the other mobile terminal. The request invokes a user interface on the other mobile terminal and prompts the user of the other mobile terminal to indicate whether or not they agree to switch from the currently active communication service to the other communication service. After receiving the user's response to the prompt, the other mobile terminal sends back a reply indicating the user's response. Signaling to perform the switch is initiated in response to the reply.
