摘要： Systems and methods can be used to maintain operation of a receiver co-located with a transmitter in a communication device and susceptible to interference therefrom by anticipating the intervals during which the transmitter is active (i.e., transmitting) and then desensitizing the receiver during that interval. Although the receiver may operate in a reduced capacity due to periodic desensitization, the adverse effects of interference generated by the transmitter can be avoided. For example, interference from the transmitter can cause variables, such as the gain applied by an automatic gain control module at the receiver input, to deviate from a normal operating or steady state value, which must then be recovered when the interference from the transmitter ceases.

摘要： A method of handling an incoming call during an operational mode of a wireless communications device is provided. When an incoming call is received at the wireless communications device, the source of the incoming call is identified. The plurality of pre-recorded messages are stored at a voice message mailbox in the wireless communications system allocated to the wireless communications device. The incoming call may be diverted, based on the identification of the caller, without completing the call and without switching to a traffic channel. One of a plurality of pre-recorded messages may then be played back to the caller.

摘要： A policy enables a subscriber to connect to multiple service providers (170,180,190) simultaneously using a network address translation technique that translates an address identifying the subscriber and associated with a first service provider into an address identifying the subscriber and associated with a second service provider for a particular application. The subscriber registers with a single home service provider (170) and connects to that single home service provider for a packet session. To connect to additional service providers (180,190) that provide additional applications during the packet session, the NAT rule is downloaded from the home service provider to a router (115) at the border between the subscriber and the access network of the home service provider. Each IP packet received at the router to or from the subscriber is filtered to determine the subscriber's address and an application identifier. Based on the combination of both the subscriber's address and the application identifier, the router translates the subscriber's address into a new address, using the NAT rule. The new address is used to connect the subscriber to an additional service provider (180,190) for a particular application during the packet session with the home service provider (170).

摘要： A time-varying trellis code is used to obtain a desired effective code rate which produces an encoder output directly mappable onto a signal constellation. The time-varying trellis code is obtained by using a variable rate encoder which produces, at its output, the correct number of bits to map directly onto the desired signal constellation. The input data stream is coded at a first code rate during a first selected time interval, and at a second code rate during a second selected time interval. By varying the code rate at periodic intervals, a third effective code rate is obtained.

摘要： A telecommunications device includes a first telephone line enabling access to a telecommunications network and a second telephone line enabling access to a telecommunications network. A selection apparatus is included which in response to an entered outgoing call number and a user generated input enables selection of one of the first and second telephone lines for supporting a call connection between the telecommunications device and the outgoing called number over the telecommunications network.

摘要： A wireless communications terminal includes a first transceiver that communicates with a first wireless communications system such as a cellular communications system. A second transceiver communicates with a second wireless communications system that typically has a shorter range than the first transceiver, such as a Bluetooth or FRS system. A multiple entry phonebook includes a first wireless communications system access number and a second wireless communications system access number for each of one or more entities. The wireless communications terminal includes a controller and/or other means that determines whether to use the first wireless communications system access number or the second wireless communications system access number in response to a request to call the corresponding entity. A wireless communication is initiated with the entity over the first wireless communications system using the first transceiver access number and the first transceiver or over the second communications system using the second transceiver access number and the second transceiver, in response to this determination.

摘要： In an audio system, a loudspeaker responds to an input signal producing a sound pressure wave having a linear component, which is linear function of the input signal, and an undesired non-linear component, which is a non-linear function of the input signal. Accordingly, it is desirable to reduce the non-linear component of the output sound pressure wave. An adaptive precompensating audio system for reducing this non-linear component includes a loudspeaker for producing a sound pressure wave and a precompensating filter for precompensating an input signal representative of the desired sound pressure wave. In addition, a microphone may be used to convert the resulting sound pressure wave into a sound signal and a precompensating filter modifier may be used to modify the precompensating filter in response to the sound signal. Preferably, the precompensating filter transforms the input signal using an inverse of an estimated transfer function for the loudspeaker.

摘要： A method and apparatus for transmitting a location service message between a location server and a mobile station or LMU in a GPRS wireless communications system. The location server generates a location service message and transmits the location service message to a base station subsystem; the base station subsystem forwards the location service message to a serving GPRS support node; the serving GPRS support node then forwards the location service message to a mobile station or LMU, passing transparently back through the base station subsystem. This approach to system routing of location messages allows existing circuit-switched wireless communications systems to support location services in a GPRS environment with a minimum or alterations to existing hardware and software protocols.

摘要： In a multiple-mode communications terminal, such as a dual-mode analog/digital cellular radiotelephone, cumulative usage of communications units in multiple modes is measured for comparison to stored critical values of tariffs for each of the modes, and measures to control usage are initiated based on an economic efficiency of the multiple modes. More specifically, expenses incurred by a communications terminal that communicates with a first mobile radiotelephone system and a second mobile radiotelephone system are controlled by storing first and second critical values which characterize a tariff structure of the respective first and second mobile radiotelephone communication systems. Communications units used by the communications terminal are measured. An economic efficiency associated with the use of the terminal to communicate with the first and second mobile radiotelephone communications systems is determined from the measured communications units and the first and second stored critical values. Measures are initiated to control communications usage with the first and second radiotelephone communications systems by the terminal based on the determined economic efficiency.
