Methods to monitor a link of transmission in a wireless communication network, and to supervise a communication link between the first and second transceivers in a communication network without aWireless and mobile station for use in a wireless communication network.A method and apparatus for monitoring link determines whether a signal link is present or absent, by measuring the energy received to that signal.If the energy measure for the signal does not satisfy a threshold energy defined according to evaluation criteria defined as a metric of sufficiency, the signal is absent.Applied to wireless communication networks, such supervision may be used to suspend or terminate the transmission, responsive to detection of the absence of the signal link.In a typical implementation for wireless networks 1xEV DV (CDMA2000 revision C), a mobile station performs selectively supervision of link of dispatch,Based on the measurement of the energy bit power control bits received by the mobile station in a CTU subchannel power control dedicated.If a reserved channel is assigned to the mobile station, this can make the supervision of link of transmission based on the estimate of the error rate (FER) framework for data received in the reserved channel.Instead of the approach based on energy.
