Abstract: Signaling a mobile unit to transmit a synchronization pattern with voice information upon detecting from the signal strength of the wireless mobile unit by a base station that the mobile unit is approaching a minimum threshold. Where the voice information is initially being transmitted in a set of frequency hopping channels using spread spectrum transmission, the synchronization pattern is transmitted in one or more of the set of frequency hopping channels. In addition, the base station alerts a system controller to this fact, and the system controller requests that neighboring base stations monitor the set of frequency hopping channels being transmitted by the mobile unit. In order to synchronize to the mobile unit, the base stations utilize the synchronization pattern to come into synchronization with the mobile unit. The system controller transfers the wireless mobile unit to the base station which is receiving the strongest signal strength.

Abstract: A method for carrying out a location updating from a mobile cellular radiophone system, such as a DECT system, to another cellular radiophone system, such as the GSM mobile phone system.

Abstract: A radio telephone system and method of operation thereof, wherein the power consumption of the mobile stations in the system is reduced. The system includes a base station, at least one auxiliary base station and at least one mobile station. The levels of the received signals are indicated at the base stations and their levels are compared. The one having the highest indicated level will be selected as the receiving base station. At the same time, the base station transmits the pilot message to the mobile station in order to adjust its transmission power to a suitably low level.

Abstract: The invention relates to a telecommunication system and a method for matching the numbering schemes of telecommunication systems. The telecommunication system comprises a transmission network comprising at least one mobile exchange (MSC1, MSC2) associated with a subsystem (BUC, BU1-BU6), the calls of subscribers (MT1-MT6) in the subsystem being routed through the transmission network and the mobile exchange. A numbering scheme of the subsystem comprises an X-bit binary subscriber identity code (PID) and a numbering scheme of the transmission network comprises a Y-decimal subscriber identity code (MSIN). In the transmission network the subscriber (MT1-MT6) of the subsystem is assigned a Y-decimal identity code comprising a decimal number derived from the X-bit binary identity code of the subscriber and having no more than Y-1 decimals.

Abstract: A system and a method for completing over a communication switching system a series of short duration calls directed to a common destination and initiated from a plurality of sources connected to a call queuing apparatus linked to the communication switching system. When the dedicated link from the call queuing apparatus to the communication switching system is in use, subsequent calls in the series are queued. Without relinquishing control of the link, these calls are thereafter connected to the communication switching system, preferably on a first-come first-serve basis. The invention allows the overhead of call setup, both cost and setup time, to be spread over the entire series of calls, as opposed to being borne by each call in the series.

Abstract: A voice Telephone Network Applications Platform (NAP) is enhanced to manage facsimile messages, as well as voice messages, by the addition of facsimile functionality to the platform actuatable by high-level facsimile commands from applications supported on the platform. The commands include sending and receiving facsimile messages. A PC facsimile processor (FP), interfacing between the platform and the telephone network, stores facsimile messages received from the network and facsimile messages for transmission to the network on hard disk. A facsimile command from an application is expanded into NAP commands for controlling the platform and FP commands for controlling the facsimile processor so as to perform the facsimile functionality associated with the facsimile command. A recovery process utilizing a Recovery Token prevents facsimile messages from becoming lost between receipt at the FP and storage in the platform.

Abstract: A cordless telephone apparatus comprising a master unit connected to a telephone line and slave units each connected to the master unit via a radio wave channel. The master unit includes a recording/reproducing circuit for recording an incoming message from a calling party on the telephone line and reproducing the recorded message in response to a request. The recording/reproducing circuit has a recording medium to record and reproduce the message, and a management area to manage the messages recorded on the recording medium. When the incoming message from the calling party is recorded on the recording medium in the recording/reproducing circuit, data for managing such message recording is registered in the management area in response to a key designation corresponding to the slave unit. And when a predetermined key operation is performed in the slave unit, the message relative to the key-operated slave unit is reproduced from the recording medium in accordance with the data registered in the management area.

Abstract: The Host Access Table (HAT) Development Facility invention provides an intelligent editor for constructing HAT command tables, using online interaction with the host to automatically insert format information from the host display panels into HAT commands being created by the writer. The resulting HAT commands direct the interaction of a teleservicing workstation with a host computer in a terminal emulation mode, to perform interactive operations with a telephone PBX and related data processing servers. The HAT Development Facility runs in a multi-tasked session with a terminal emulation program in the workstation, allowing the writer to directly interact with the terminal emulation program while creating the HAT commands using the HAT Development Facility. An optional real time test mode is also provided.

Abstract: A method and apparatus for preprocessing digital voice data enroute to or from a Telephone's CODEC. The apparatus supports a CODEC directly connected to an internal bus and using a separate CODEC clock and sync signal to control transfers between a telephony link/internal bus interface and the CODEC. According to an embodiment of the present invention, an auxiliary processing device (connected to the internal bus side of the phone) is provided with means to process the digital voice information before sending it uplink or to the CODEC. This is accomplished without changing the position of the incoming voice field.
