20 Feb 2001TL;DR: In this paper, a method for supporting mobility in a wireless telecommunication system which comprises at least one terminal, an access point currently serving the terminal and a plurality of other access points is presented.
Abstract: A method for supporting mobility in a wireless telecommunication system which comprises at least one terminal, an access point currently serving the terminal and a plurality of other access points. The access points may be grouped into networks and the terminal is arranged to collect information about available access points. The network names of the available access points are checked by the terminal. The first access point with the best connection attributes of the available access points with the same network name as the currently serving access point is selected. The second access point with the best connection attributes of the available access points with a different network name than the currently serving access point is also selected. One or more connection attributes of the first access point and the second access point are compared. The connection to the second access point is established if the differences between the compared connection attributes fulfil pre-determined conditions.

12 Dec 1996TL;DR: In this article, a short message or other reply message is sent in response to an incoming call, in a situation where the user can't answer the call him/herself.
Abstract: In a communication device (20) comprising a message function (SMS, Short Message Service) a certain short message (7) or other reply message is sent in response to an incoming call in a situation where the user can't answer the call him/herself. The reply message can be sent immediately (9) or after a short delay (10, 11), whereby during the delay, the user can choose, whether he/she answers him/herself. The calling party (5) is identified from the CLI information (Caller Line Identity), whereby the reply message can be chosen according to the calling party. Time information can be included in the reply message in order to express at which time by the clock or after a how long time the receiving party is reachable. After that time the automatic reply function based on the reply message is automatically disconnected.

06 Oct 1999TL;DR: In this article, an enhanced acknowledgement pacing device (500) and method for TCP connections is disclosed, which includes an acknowledgement control unit (510) for monitoring congestion at the link layer entity (528) and generating a control signal for controlling the processing of acknowledgement packets (532).
Abstract: An enhanced acknowledgement pacing device (500) and method for TCP connections is disclosed. The invention includes a link layer entity (528) for receiving data packets from a source and forwarding the data packets (540) to a forward data link, the link layer entity (528) storing the received data packets (540) in a data packet buffer (530) until the data packets depart the link layer entity (528) and are forwarded to the forward link and an acknowledgement pacing device (500), coupled to the link layer entity, for pacing acknowledgement packets (532) to be sent to the source in response to receiving the data packets (540) from the source (540). The acknowledgement pacing device (500) further includes an acknowledgement control unit (510) for monitoring congestion at the link layer entity (528) and generating a control signal for controlling the processing of acknowledgement packets (532) based upon whether congestion is occurring at the link layer entity (528), an acknowledgement packet buffer (534), coupled to the acknowledgement control unit (510), for storing acknowledgement packets (532) received from the acknowledgement control unit (510) and a scheduler (520), coupled to the acknowledgement control unit (510) and the acknowledgement buffer (534), the scheduler (520) releasing acknowledgement packets (532) to the source (540) based upon the control signal generated by the acknowledgement control unit (510).

14 Jul 1993TL;DR: In this article, a dual mode transmitter with bias control is described, where an RF signal from a system modulator is fed to a gain control circuit, which can be either a voltage controlled amplifier or attenuator.
Abstract: A dual mode transmitter with bias control is described wherein an RF signal from a system modulator is fed to a gain control circuit, which can be either a voltage controlled amplifier or attenuator. The ultimate transmitter output power level depends on the attenuation/gain of the gain control circuit. The output signal from the gain control circuit is fed to a driver amplifier which amplifies the signal and feeds it to a power amplifier circuit, which may be comprised of several stages of bipolar transistors or GaAs FETs. The modulated signal to be transmitted is then fed from the power amplifier circuit through a coupler to an antenna terminal. The coupler is connected to an RF detector and is used for RF level monitoring. The Rf level signal from the RF detector is applied to a comparator circuit. An improved combination is provided by incorporating a bias control circuit. A Vpwr signal is applied as one input to the bias control circuit and a mode signal is applied as the other input. When the mode signal is "on" or present it signifies that the digital transmission mode is to be employed. When the mode signal is " off" or at zero level, it indicates that the analog transmission mode is to be employed. The bias control circuit provides three bias signal outputs, Vb1 applied to the driver amplifier, and Vb2 and Vb3, applied to the power amplifier. The levels of Vb1, Vb2 and Vb3 are varied for the analog and digital transmission modes.

17 Jul 1995TL;DR: In this paper, a method for starting a short message transmission in a cellular communication system, including a cellular system, a cellular network, and a cellular communications system subscriber location register, was proposed.
Abstract: The present invention relates to a method for starting a short message transmission in a cellular communication system, a cellular communication system, and a cellular communication system subscriber location register, in which method the subscriber location register (10; HLR) stores information on the fact that at least one short message service center (SC1, SC2, SC3) stores short messages to be transmitted to a subscriber (MS), to whom they cannot be transmitted for the time being, and the subscriber location register (10; HLR) of the subscriber (MS) transmits to said at least one short message service center (SC1, SC2, SC3) a short message transmission starting message when it is possible again to transmit short messages to the subscriber (MS). In order that short messages could be transmitted to subscribers (MS) selectively, the subscriber location register (10; HLR) maintains, short message service center (SC) - and subscriber (MS) - specifically, information (11) on the conditions on which the short message service center (SC1, SC2, SC3) is transmitted short message transmission starting messages.
