    摘要： A data collection system in which, in communications between each of terminal units and a data collector through a power line, the data collector subjects a polling signal generated by a polling generating circuit to spread spectrum modulation by a spreading section, and superimposes the spread signal on the power line, while each of the terminal units subjects the incoming spread signal thereto superimposed on the power line to de-spread spectrum demodulation and recognizes it, and superimposes the data subjected to spread spectrum modulation on the power line after a certain period of time different from that in other terminal unit has passed. The data collector collects the data obtained by subjecting spread signals successively coming thereinto each by being superimposed on the power line to de-spread spectrum demodulation according to the polling.

    摘要： A radio communication system in which each frame having an imbalanced transmission speed is time-divided to a low speed transmission area and to a high speed transmission area according to a specified ratio in the time domain. An upload signal as a first-directional signal and a download signal as a second-directional signal are allocated to the low speed transmission area and to the high speed transmission area respectively. In a case where a high speed transmission request is issued from a personal station (PS) to a base station (BS), the order of the upload signal and that of the download signal is exchanged in the time domain within one frame, so that the download signal and the upload signal are allocated to the low speed transmission area and the high speed transmission area respectively.

    摘要： An integrated cellular and cordless communication system in which cellular calls are forwarded to a landline telephone number associated with a personal base station when a subscriber terminal is determined to be within a predefined vicinity of the personal base station is described herein. Once forwarded to the personal base station via external network elements, such calls may be answered using a cordless device operative to communicate with the personal base station. Alternately, the calls may be transferred to a voice messaging module within the personal base station. When the subscriber terminal is determined to have been removed from within the vicinity of the personal base station, a message from the personal base station to the external network elements results in modification of a call forwarding address such that subsequent calls intended for the subscriber terminal are in fact routed thereto. The personal base station may also be optionally implemented to enable the forwarding of calls intended for the personal base station to the subscriber terminal. A subscriber could indicate the desire for this type of call forwarding by way of, for example, a user interface of the personal base station. In response, the personal base station would issue a request to the external network elements to forward subsequent calls intended for the landline telephone number of the personal base station to the subscriber terminal.

    摘要： A communication system is provided whereby desired information can be transmitted in accordance with conditions and the application. The communication system includes a PHS terminal and a provider system that is capable of information communication with this terminal. The PHS terminal has a voice recognition section that receives voice from a microphone and recognises the received voice signal, an input device that selects the output form of the voice signal, a conversion section that converts the recognised voice signal with the selected output form, and a transceiver that transmits the converted voice signal to the provider equipment; the converted voice signal is further transferred from the provider system to another destination wireless communication terminal device. This output form includes for example “dialect”, “intonation/imitated voice of a celebrity etc.” or “modulation”. Conversion filters convert the voice signal in accordance with these.
