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： A method and system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.

摘要： A method and system is disclosed for enhanced setpoint adjustment during extended frame decoding. In accordance with an example embodiment, upon determining that a frame transmission from an access terminal has not been successfully decoded during a nominal frame period, a base station will commence an extended decoding interval. The base station will also determine a transition point time that is within a range of times from the beginning to the end of the extended frame decoding interval. The determination of the transition point time will be based on the nominal setpoint in place during the preceding nominal frame period. Upon reaching the transition point time, the base station will increase the current (nominal) setpoint. Accordingly, the setpoint for the access terminal may be increased at a point in time that precedes the completion of the extended decoding interval.

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.

摘要： Exemplary methods and systems involve a determination of when a rapid page attempt should be made in the sector where a mobile station's last call ended, before zone-based paging is initiated. An exemplary method may involve a radio access network: (a) determining that a mobile station should be paged; (b) before sending the page, the RAN determining whether or not both: (i) a rapid page attempt to the mobile station is likely to succeed, wherein a last call of the mobile station ended in a sector within a first paging zone, and (ii) the rapid page attempt to the mobile station is likely to reduce paging-channel occupancy in the first paging zone; (c) if it is determined that both: (i) the rapid page attempt to the mobile station is likely to succeed and (ii) the paging-channel occupancy is above the threshold level in at least one other sector in the first paging zone, then the RAN making a rapid page attempt in the sector of the radio access network in which the last call ended; and (d) otherwise, the RAN using a zone-based paging scheme to page the mobile station.

摘要： A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

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： A method is disclosed for implementing an overlay carrier frequency in a wireless coverage area in response to low load in the coverage area. Normally, an carrier frequency may be added in response to high load. However, the disclosed method involves adding a carrier frequency in response to low load, as the addition of a carrier may advantageously increase the likelihood of soft handoff in certain situations, and as low load may facilitate operation on the added carrier without the need to add expensive supporting infrastructure that would typically be added to support full operation on an added carrier frequency.
