    摘要： Voice recording and playback mode using the G.726 half-rate within the personal handy phone system (PHS). When a portable station within the PHS operates as a voice recorder (e.g., functioning as an answering machine), a cost effective system in accordance with the present invention is adapted to compress and store received voice/sound signals in order to increase the usage of limited memory resources provided within the portable station. The present invention also enables previously compressed and stored voice/sound signals to be decompressed and played back in various portable station playback modes. Specifically, the portable station receives a voice/sound signal in a full rate (e.g., 32 kilobits-per-second) 4-bit adaptive differential pulse code modulation (ADPCM) data format in compliance with the International Telecommunication Union (ITU) recommendation G.726. The present invention compresses this received voice/sound signal to a half rate (16 kilobit-per-second) 2-bit ADPCM data format in compliance with the ITU recommendation G.726 in order to increase the usage of the limited memory resources provided within the portable station. During a playback mode of the portable station, the present invention decompresses the previously compressed and stored voice/sound signal to facilitate its playback.

    摘要： A system for a direct digital down conversion of a 10.8 MHz intermediate frequency signal in the personal handy phone system. The present invention includes a system that enables a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal within cell stations and portable stations of the personal handy phone system. To perform this direct digital down conversion of a 10.8 MHz intermediate frequency signal, one embodiment of the present invention uses a hard limiter circuit, a sampler circuit and a digital down converter circuit. The hard limiter circuit of the present invention receives a 10.8 MHz intermediate frequency signal, utilized within cell stations and portable station of the personal handy phone system, and provides a threshold for it. The sampler circuit uses a 19.2 MHz oscillating clock signal to sample the intermediate frequency signal that is output from the hard limiter circuit. Due to spectral leakage, the 10.8 MHz intermediate frequency signal that was input into the sampler circuit is output as an 8.4 MHz intermediate frequency signal. The digital down converter circuit uses an 8.4 MHz signal to perform a digital down conversion of the 8.4 MHz intermediate frequency signal into a digital baseband signal. The present invention provides a system that utilizes only one digital down conversion stage to perform a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal.

    摘要： A method and system that enables an automatic delay setting within a wireless local loop system. The present invention determines the transmission distance time delay existing between a base station and a personal station by employing the communication interface that is utilized between them. The main reason for determining the transmission time delay caused by large transmission distances (e.g., over 300 meters) existing between base stations and personal stations is to compensate for it. Once the transmission distance time delay is known, the personal station utilizes that value to compensate for it. Specifically, the present invention directs a base station to transmit a control signal to a personal station. The personal station receives the control signal and transmits a signal to the base station. The base station determines if it started to receive the signal from the personal station later than it expected the signal to arrive, assuming close proximity of the two stations. If the signal arrived when it was expected to arrive, the base station discontinues determining the transmission distance time delay. If the signal arrived later than expected, the base station calculates the time difference between the expected arrival time and the actual arrival of the signal. The time difference is equivalent to the transmission distance time delay. Once the time difference is determined, the base station then transmits it to the personal station. The personal station stores the transmission distance time delay value enabling it to compensate for it.

    摘要： A system that enables a portable station of the personal handy phone system to support a conference call. The present invention provides this capability by empowering a portable station to communicate with up to four cell stations simultaneously enabling the user of the portable station to communicate with the users of four other telecommunication devices. Specifically, the present invention modifies the internal circuitry of a portable station to increase the number of receiving channel circuits to four and the transmitting channel circuits to four while adding a digital signal processor to mix the different received and outgoing voice signals. The increased number of receiving and transmitting channel circuits enables a portable station to utilize all the communication slots located within the frames of the radio communication interface of the personal handy phone system. Communication is time-multiplexed across these slots. The frames each have eight slots, four for receiving data and four for transmitting data. These eight slots enable a portable station implemented with the present invention to support communication with four cell stations simultaneously. To facilitate this type of communication, the slots located within the portable station frames operate in conjunction with the slots located within the cell station frames of the cell stations involved in the conference call thereby creating communication channels. The cell stations involved in the conference call each utilize different communication channels to communicate with the portable station implemented with the present invention.

    摘要： A method for remotely updating software code of personal handy phone system equipment. The present invention enables a remotely located control terminal to update stored software code within a distant portable station or cell station of the personal handy phone system. Specifically, by coupling a control terminal to the existing communication network of a personal handy phone system, the control terminal is able to communicate with portable stations and cell stations. To update the software code of a specific portable station or cell station, the control terminal first establishes communication with that particular device by sending an unique preparatory signal addressed to it. The addressed device receives the unique preparatory signal and checks the validity of it. If the addressed device determines the unique preparatory signal is valid, it transmits a unique verification signal addressed to the control terminal indicating that it is ready to receive the updated version of the software code. Once the control terminal receives the unique verification signal from the particular portable station or cell station, it proceeds to download an updated version of software code into the flash memory of that device.
