摘要： A method and system is disclosed for dynamically adjusting a signal-to-noise (SNR) bias based on relative load between a macro type base station and a micro type base station of a wireless communication system. The SNR bias corresponds to a threshold differential SNR between SNRs of the macro base station and of the micro base station, wherein the SNR bias is configured to be provided to an access terminal (or user equipment) to cause the access terminal (i) to be biased to seek service from the micro base station if the access terminal detects an SNR from the micro base station that is less than the threshold differential SNR below an SNR that the access terminal detects from the macro base station, and (ii) to be biased to seek service from the macro base station otherwise. Once the SNR bias is determined based on the relative load, it is communicated to one or more access terminals.

摘要： Methods and devices for a radio access network (RAN) to select a wireless communication device (WCD) for handoff to a given sector are presented. In particular, the RAN may receive resource requests from a first WCD and a second WCD, both WCDs contending for a resource of the given sector. Based on the each WCD's active sets of sectors, the RAN may grant the resource to one of these WCDs. Preferably, the RAN grants the resource to the WCD that is more likely to benefit from use of the resource.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

摘要： Methods and devices for mitigating the impact of handoffs to non-preferred wireless coverage areas are presented. In particular, a RAN may determine that a first wireless communication device (WCD) and a second WCD are contending for a resource of a preferred wireless coverage area, and that both of the WCDs are likely to be handed off to different non-preferred wireless coverage areas if they are not granted the resource. Both WCDs may be subscribed to a home wireless service provider that also controls and/or operates the preferred wireless coverage area. The RAN may compare the roaming fees of a first non-preferred wireless coverage area with the roaming fees of a second non-preferred wireless coverage area. Based on the outcome of this comparison, the RAN may allocate the resource to the WCD that would likely incur higher roaming fees to the home wireless service provider if that WCD were to roam to a non-preferred wireless coverage area.

摘要： A method and system is disclosed for enhanced idle-state sector selection during hybrid-mode operation of an access terminal. A hybrid access terminal engaged in an IS-856 data communication session in a hybrid IS-2000/IS-856 wireless communication system will, responsive to a handoff of the IS-856 session, select a sector for its next, upcoming IS-2000 idle-state scan prior to the start of the scan. The selection will be made during an interval between IS-2000 idle-state scans, thereby reducing or eliminating the possible need for idle-state handoffs during idle-state scans, and resulting in shorter idle-state scans and better IS-856 performance.

In particular, a RAN may determine that a first wireless communication device (WCD) and a second WCD are contending for a resource of a preferred wireless coverage area, and that both of the WCDs are likely to be handed off to non-preferred wireless coverage area(s) if they are not granted the resource. Both WCDs may be subscribed to a home wireless service provider that also controls and/or operates the preferred wireless coverage area. The RAN may compare historical call length data of the first WCD with historical call length data of the second WCD.

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.
