摘要： Systems, methods, and computer-readable media for adjusting a timer mechanism based on radio frequency (RF) conditions of a network connecting source and destination devices are provided. Initially, data packets transmitted by the source device are assigned an ordering. This ordering is compared to an actual order in which the data packets are received at the destination device to ascertain whether any data packets were missing due to RF conditions. A negative response indicating missing, or lost, data packets may be returned, thereby invoking the source device to retransmit the data packets identified as missing. The device(s) may compute a probability of packet-loss (utilizing a recorded history of the transmitted packets in conjunction with the data packets actually received) and utilize the packet-loss probability to dynamically tune a time-interval of the timer mechanism. Upon expiration of the time-interval, the timer mechanism instructs the source device to retransmit the initial data packets.

摘要： Methods and systems provide dynamic determination of a control-channel bit rate. An access node provides service on a carrier comprising active and idle timeslots, active timeslots comprising a data channel for carrying a control channel at a bit rate that can be set to a lower value or a higher value, and traffic channels. The access node determines whether the number of active timeslots over a time period is less than a first threshold. If so, the access node sets the bit rate to the lower value. If not, the access node sets the bit rate to the higher value if at least one of the following is true: (a) control-channel occupancy exceeds a second threshold, (b) the amount of data in a traffic buffer exceeds a third threshold, and (c) control-channel occupancy exceeds a fourth threshold and the amount of data in the traffic buffer exceeds a fifth threshold.

摘要： An access network may identify paging areas based on a reference location (e.g., a mobile station's last known location), where each paging area includes at least one coverage area. The access network may then determine paging-channel occupancies for coverage areas in at least identified paging area. In turn, the access network may adjust a given identified paging area based on the determined paging-channel occupancies, resulting in an adjusted paging area. For example, the access network may add coverage areas to the given identified paging area and/or remove coverage areas from the given identified paging area based on the paging-channel occupancies for those coverage areas. Thereafter, the access network may page a mobile station associated with the reference location in the adjusted paging area.

摘要： A method and system for monitoring data rate requests (DRRs) transmitted from an access terminal (AT) to an access network (AN). Each DRR includes a parameter indicating whether it is a null or non-null DRR. Upon the AT transitioning to a null-DRR state, the AT and AN determine an average parameter of a given number of DRRs and compare the average to a threshold. The AT selects a time duration based on the average and starts a timer. When the timer counts to the selected duration, the AT transitions from a mode in which the AT transmits data channel traffic and other traffic to a mode in which the AT prevents transmission of data channel traffic but allows transmission of other traffic. The AN compares the average to another threshold and determines whether it should transmit forward-link traffic channel data to the AT at a null or non-null data rate.

摘要： Systems and methods for dynamically adjusting a metric that influences power management of an access terminal are provided. Initially, an access node is configured to distribute reverse-activity bits (RAB's) to the access terminal, which conveys data, at a particular rate, to the access node. Adjusting the dynamic metric involves establishing a number of slots allocated for a filtered reverse-activity bit (FRAB) window and a hybrid reverse-activity bit (HRAB) window, wherein each of the slots are allocated to accept a RAB. The RAB's accepted to the slots of the FRAB window and the HRAB window are recursively averaged to derive a FRAB parameter and an HRAB parameter, respectively. The dynamic metric is adjusted by incorporating either the FRAB parameter or an HRAB parameter therein based on whether ramping conditions are satisfied. The rate of data conveyed from the access terminal is controlled based on the adjusted dynamic metric.
