Abstract: A communication terminal having a display; a keypad having a plurality of keys associated with several letters each; and a processor controlling the display in accordance with the operation of the keypad. The processor runs a predictive editor program for generating an output containing a word matching a received string of ambiguous key strokes. Furthermore an editor application is controlled by the processor for editing a text based on the predictive editor program's interpretation of key strokes received from the editor application. The editor application stores a list of matching words received from the predictive editor program, at least a part of the text string is displayed in the display. The keypad includes at least one softkey whose functionality is displayed in the display and controlled by the processor.

Abstract: The invention relates to a cellular radio system and a method of ciphering data transmission in a radio system that comprises at least one transceiver communicating with other transceivers on a radio connection including one or more parallel radio bearers or logical channels, ciphering being performed on said bearers or logical channels using selected ciphering method parameters. Ciphering is performed on said bearers using selected ciphering method parameters.

Abstract: A method for quickly de-allocating physical channels (PDCH) assigned to packet switched calls in a GPRS supporting GSM digital cellular telephone network. An PDCH de-allocation RLC/MAC control message is broadcast to listening mobile stations from a base station subsystem (BSS) and contains a temporary flow identity (TFI) which is recognised by the listening mobile stations (MS). The mobile stations respond by terminating packet switched data transmissions on the identified PDCHs. The RLC/MAC message also identifies the number of PDCH time slots which can be used before de-allocation must occur.

Abstract: A battery charging circuit is described in which power is derived from a communications port such as a USB interface (22) and is supplied to a rechargeable battery of a communications device. The communications device, which may be a mobile radio telephone, can be charged from the power supply or internal battery of a laptop computer equipped with a USB port and connected thereto with a suitable cable thereby avoiding the need for a user to carry a dedicated battery charger for the radio telephone.

Abstract: A motion estimation system for a video coder has an input for a video image to be coded, and includes a series of motion estimators of varying complexity for estimating a motion vector field between a received image and a reference image. The estimation is accomplished by sequential use of the estimators, wherein a subsequent estimator of the sequence is selected by a controller based on a prediction error, associated with the motion vector field estimated by a currently selected estimator, exceeding a predetermined threshold.

Abstract: The invention relates to a method for transmitting video images between multimedia terminals (1,1′) in a data transmission system. In the video image transmission first video frames (I) are used, in which information encoded from one video image is transmitted, as well as second video frames (P, B) in which information encoded on the basis of two or more video images is transmitted, from which it is possible to generate a video image in the receiver multimedia terminal (1) by using at least one first (I) and at least one second video frame (P, B). In the method, the fast forward or fast rewind function of the video images is performed by transmitting primarily only first video frames (I).

Abstract: A patch antenna is provided with two feed points, one on either side of a cut-out. Both feed points are connected to the ports on a first side of a matrix switch, one directly and one via a capacitor. An antenna feed is connected to one of the ports on a second side of the matrix switch, while the other is earthed. In use, a controller operates the switch so that the antenna feed is connected one or other of the feed points, each giving rise to a different resonant frequency and so providing a way of tuning the antenna for small frequency shifts.
