Abstract: [PROBLEMS] To realize power saving of a receiver apparatus for receiving time-division multiplexed signals. [MEANS FOR SOLVING PROBLEMS] In the receiver apparatus, power is supplied to a receiver circuit in accordance with an operation start time. A signal is received through the receiver circuit, and a quality of the received signal is evaluated by a signal quality evaluation unit 109. Control is exercised to set a late operation start time if the quality of the received signal is good, and an early operation start time if the quality of the received signal is bad. In this way, a period for supplying power to the receiver circuit can be adjusted according to the quality of the received signal. This makes it unnecessary to fix, as in conventional techniques, a long power supply period in consideration of the case where the signal quality is bad. As a result, more power saving can be achieved.

The monitoring/control device determines whether GMPLS-not-implemented nodes exist on a GMPLS control target LSP, when they exist, performs all settings necessary for the GMPLS-not-implemented nodes, and then transmits a GMPLS control suspension release message to resume the GMPLS control.

Abstract: Collisions between messages simultaneously transmitted by multiple spread-spectrum transmitters are reduced by distributing the transmissions over the available resources of the receiver. Each mobile station in a CDMA system uses one or more randomization methods to distribute its transmissions. In the first randomization, the mobile station time-delays its transmissions by a number of chips of the PN code with which it spreads the transmitted signal. In a second randomization, the mobile station randomly selects the PN code. In a third randomization, the mobile station inserts a random delay between successive message transmissions or probes if it does not receive an acknowledgement after a predetermined timeout period. A predetermined number of such transmissions is called a probe sequence. In a fourth randomization, the mobile station inserts a relatively long random delay between successive probe sequences if it does not receive an acknowledgement of any probe in the sequence.
