Abstract: Integrated holster and audio appliance for a radiotelephone. The audio appliance includes a speaker and a microphone, spaced apart and connected by an extension that can be extended to position the speaker and the microphone near a user's ear and mouth and that can be folded or collapsed to fit into the holster with the radiotelephone. The radiotelephone need not be removed from the holster to receive and respond to calls. When the radiotelephone is positioned in the holster, electrical power for one or more selected radiotelephone components (display screen, touch sensitive screen, keypad, etc.) is optionally reduced or withdrawn to conserve battery charge, and a built-in speaker and a built-in microphone for the radiotelephone are optionally disabled. The system includes an optional retraction mechanism to retract an electrical cable associated with use of the audio appliance into the holster when the audio appliance is not in use.

Abstract: A system and method is provided that provides a mobile communication device with the ability to quickly reestablish a communication session with another after the communication device is awaken from a sleep or idle mode. The mobile communication device is provided with a first power system for powering a central operating system and a second power system for powering a communication system. A mobile communication device establishes a communication session with another communication device by establishing a connection and establishing a communication session. During an idle period, the communication session in a stack will be stored in memory. The first power system and the central operating system will then enter a low power or sleep mode, while second power system and the communication system can maintain a communication connection with the other device. Upon reestablishing communications, the mobile communication device will wake up the first power supply and the central operating system.

Abstract: A method and apparatus for long code group determination. The long code group is determined based upon a number of symbols in a received codeword, wherein the number of symbols is less than the total number of symbols in the codeword. The long code group number can be determined either through the use of a table of code sequences or through a reduced complexity code search. The use of the of these techniques allows for a quick determination of the long code group used by a particular base station.

Abstract: In a cellular telecommunications system or network, tags are associated with one or more system control parameters. For example, a given tag value may be indicative of particular values for one or more system information parameters. In each cell, a base station (BS) transmits or broadcasts currently valid tag values. System information blocks including the system information parameters themselves (which correspond to particular tag(s)) are also broadcast by base stations. A mobile station receiving a valid tag value from a base station determines whether or not it has to read system information block(s) corresponding to that tag value depending upon whether the base station has already stored or cached such block(s) corresponding to the tag value. As will be appreciated by those skilled in the art, different embodiments of the instant invention may result in the mobile station not having to re-read identical system information each time it changes cells, or while moving in the same cell.

Abstract: A remote unit (101) monitors a control channel for a base station (103) and sends a probe message (301) to the base station (103). The base station (103) forwards the probe message with location information (305) to a controller (115). The controller (115) determines an approximate distance for the remote unit (101). Based on the approximate distance, the controller (115) determines at least one additional site. A channel assignment message (309 or 401) is forwarded to the remote unit (101), which message includes one or more traffic channels associated with at least one of the base station (103) and the at least one additional site.

Abstract: Apparatus, and an associated method for facilitating the performance of three-call operations, such as a call-waiting feature, at a mobile station.

Abstract: A method and network element for fast forward power control in a CDMA network includes establishing an artificial FPC_SUBCHAN_GAIN parameter having a value different from an actual FPC_SUBCHAN_GAIN parameter. The actual FPC_SUBCHAN_GAIN parameter represents an actual amount of power by which a punctured bit has been increased or decreased. The artificial FPC_SUBCHAN_GAIN parameter is substituted in place of the actual FPC_SUBCHAN_GAIN parameter during fast forward power control. The value of the artificial FPC_SUBCHAN_GAIN parameter is selected to compensate for a diversity gain occurring as a result of an adding of a link or a dropping of a link between at least one base station transceiver and a mobile station. Lastly, the artificial FPC_SUBCHAN_GAIN parameter is sent from the at least one base station transceiver to the mobile station.

Abstract: A system provides interactive control of broadband services. There are today systems which offer distributive services, for instance analog cable-TV, analog satellites and acting terrestrial TV-networks. A paradigm shift, however, has been initiated in connection with that digital transmissions have started, which make possible a more spectrum efficient transmission. This means, for instance, that a broadband service such as digital transmission of video channels can be developed by making it interactive. One solution can be to use the GSM-system. For example, services which require low capacity in uplink can utilize the SMS-function is GSM. At larger demand of bandwidth GSM's data services can be utilized, which however prevents calls when the telephone is used for interactive communication. The invention solves this problem by interactive traffic between the transmitting and receiving equipment being managed by an interactive center (IC) which is arranged to execute wanted broadband service.

Abstract: A method and system for controlling an accessory function by a cellular telephone are disclosed. In accordance with the method, the cellular telephone generates a message payload comprising a command to set a selected register on an accessory device to a selected value. The cellular telephone transmits the message payload to the accessory device. The selected value is stored in the selected register on the accessory device in response to the message payload. The accessory device periodically reads the contents of the selected register. The accessory device controls the accessory function in response to the contents read from the selected register. The simple message protocol uses memory and bandwidth resources efficiently, and allows additional accessory functions to be readily controlled without significant modifications to the protocol.

Abstract: The invention provides an up/down converter with low phase noise. Signals from a first local oscillator are fed through a power splitter to first and second mixers. Signals from a second local oscillator and signals from the power splitter are mixed by the second mixer. The frequency component of the difference between the two signals is removed by a first bandpass filter and passed to a third mixer. Input signals are mixed with signals from the power splitter by the first mixer, and the lower frequency component of the output signals from the first mixer is removed by a second bandpass filter and is passed to the third mixer. Signals from the first and second bandpass filters are mixed by the third mixer. The higher frequency component of the output signals is removed by a low pass filter and is output.
