摘要： A system and method for call screening in a wireless telephone system. When a call is received on an answering machine (17) associated with a base part (11), the user at a portable part (12) may select a call screen button (19). The resulting signal is received at the base part (11), which then enters a broadcast mode. The incoming answering machine message is broadcast to all handsets (12, 14, 16). In a TDMA system, an audio message is broadcast from a base part (11) during a single time slot of a time division. The user at a particular portable part may then select a pick up button to pick up the call.

摘要： Methods and apparatus for combined wireless telephony and data communication of the present invention include providing a Home RF transceiver and a WDCT transceiver in a common enclosure and synchronizing the operation of the Home RF transceiver to specific time slots in the WDCT TDM frame. More particularly, the Home RF transceiver is prevented from transmitting whenever the WDCT transceiver is receiving and is prevented from receiving whenever the WDCT transceiver is transmitting. This effectively prevents the Home RF transceiver from interfering with the WDCT transceiver and vice versa. According to a presently preferred embodiment, synchronization is keyed to the repeating WDCT TDM frame but is dynamically adjustable based on the actual use of bandwidth by the WDCT devices. Thus, when there is no telephony traffic, the Home RF transceiver has full bandwidth. For each WDCT telephone call in progress, no more than 1/12 of the Home RF transceiver bandwidth is sacrificed. The methods and apparatus of the invention allow the reuse of key components from existing standards to provide a combined voice and data base station. The invention also takes advantage of two proven technologies to achieve its goals.

摘要： Providing an audio broadcast for a TDMA system. During a single time slot, an audio message is broadcast from a base art and received at a number of portable arts. An audio broadcast command is generated by designating the single time slot and then transmitted to the plurality of portable parts. An additional portable part transmits a broadcast origination signal and the audio message to the base part which transmits the audio broadcast command to the portable parts. by assigning a time slot other than the designated time slot to a portable part, the portable part does not broadcast audio messages during the designated time slot. More than three receiving time slots and more than three sending time slots are divided out for the base art that includes the designated time slot. The audio broadcast command is transmitted during at least two of the more than three sending time slots.

摘要： A frequency hopping spread spectrum telecommunication system is provided, which selects carrier frequencies based on the number of active slots. The duration that carriers have been employed is then based on the number of active slots (401, 402), rather than the number of frames (22). Thus, non-interfered with carriers can be used more often than interfered with carriers, thereby improving voice quality.

摘要： A method for avoiding interference in a wireless telecommunication system is provided. The method includes providing communication between a first and second component at an initial frequency. A plurality of successive line quality indicators is determined at a line quality monitor of the first component. Consecutive line quality indicators are summed over a predetermined time to determine a slow hop count. A determination is made as to whether the slow hop count is greater than a slow hop threshold. A determination is made as to whether to provide communication with the first component at a second frequency when the slow hop count is greater than the slow hop threshold. This determination is based on a power level of the second component and a communication strength received from the second component at the first component. A signal is communicated from the first component to the second component requesting the second component to provide communication at the second frequency.

摘要： Carrier signals received by a receiver architecture for an amplitude spectrum of the carrier signal prescribed by the employment of the receiver architecture even given small modulation indices, a low-noise amplifier (VS) preceding a synthesizer (SYN) of the receiver is either turned off dependent on the field strength received with the carrier signal or is fashioned such that the maximum output power of the amplifier (VS) at the possible amplitude spectrum of the carrier signal never lies above the compression point of the mixer/mixers in the synthesizer (SYN).
