Abstract
An intermittent operative communication apparatus can send data, received from a source communication device, to any receiver communication device at a predetermined interval and wait for receiving data at the predetermined interval. The communication apparatus has a selector for selecting one or multiple receiver communication devices as a reference communication device that gives a reference timing at which the communication apparatus waits for receiving data, and a timing controller for setting a timing, at which the communication apparatus waits for receiving data, to a timing according to operation of any reference communication device.
Claims18
An intermittent operative communication apparatus for use in a telecommunications system including a plurality of communication devices, said apparatus waiting for receiving data at a predetermined interval and sending data received from a source device among the plurality of communication devices to a receiver device among the plurality of communication devices, said receiver device waiting for data at the predetermined interval, said apparatus comprising:
- a selector for selecting one of the plurality of communication devices as a reference device that has a reference timing at which said reference device waits for receiving data;
- a timing controller for setting a receiving timing at which said apparatus waits for receiving data;
- and
- a timing estimator to estimate a timing that corresponds to the reference timing of the reference device by using a timing at which a response signal, that is transmitted in response to a signal from the apparatus, is received from said reference device or another timing at which data are sent to said reference device,
- said timing controller setting the receiving timing to be the timing estimated by said timing estimator shifted by a predetermined value.
A telecommunications system comprising a plurality of communication devices, said devices waiting for receiving data at a predetermined interval and sending data received from a source device among the plurality of communication devices to a receiver device among the plurality of communication devices, said receiver device waiting for data at the predetermined interval, wherein one of the plurality of devices is operative intermittently and comprises:
- a selector for selecting one of the plurality of communication devices as a reference device that has a reference timing at which said reference device waits for receiving data;
- a timing controller for setting a receiving timing at which said device waits for receiving data;
- and
- a timing estimator to estimate a timing that corresponds to the reference timing of the reference device by using a timing at which a response signal, that is transmitted in response to a signal from the one device, is received from said reference device or another timing at which data are sent to said reference device,
- said timing controller setting the receiving timing to be the timing estimated by said timing estimator shifted by a predetermined value.
A communication method in an intermittent operative communication apparatus for use in a telecommunications system including a plurality of communication devices, the apparatus waiting for receiving data at a predetermined interval and sending data received from a source device among the plurality of communication devices to a receiver device among the plurality of communication devices, the receiver device waiting for data at the predetermined interval, the apparatus including a selector, a timing controller and a timing estimator said method comprising the steps of:
- selecting, by the selector, one of the plurality of communication devices as a reference device that has a reference timing at which said reference device waits for receiving data;
- setting, by the timing controller, a receiving timing at which the apparatus waits for receiving data;
- estimating, by the timing estimator, a timing that corresponds to the reference device by using a timing at which a response signal, that is transmitted in response to a signal from the apparatus, is received from the reference device or another timing at which data are sent to the reference device;
- and
- setting, by the timing controller, the receiving timing to be the timing estimated by said timing estimator shifted by a predetermined value.
