    摘要: A communication system comprises a wireless access node having a plurality of ports and a control system. The wireless access node is configured to exchange wireless communications over the ports with wireless communication devices that are individually identified by device identifiers. The control system is configured to individually allocate the wireless communication devices into categories based on the device identifiers and determine one of the categories having a majority of the wireless communication devices. The control system is configured to configure the ports of the wireless access node to utilize a MIMO 2T2R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a first data rate capability, and to configure the ports of the wireless access node to utilize a MIMO 4T4R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a second data rate capability.

    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: 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: 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.

    摘要: Disclosed is a method and system to help reduce the extent of roaming or use of lower priority coverage areas in a wireless communication system, by selectively managing the level of noise in a preferred coverage area. A network entity will detect that a particular coverage area has a high rate or roaming or that another coverage area (e.g., a collocated or adjacent coverage area) has a high rate of use, and the network entity will responsively reduce a noise threshold in the particular coverage area so as to then tolerate less noise in the coverage area before taking affirmative action to reduce the level of noise, and thus optimally to reduce the extent of roaming or use of less preferred coverage.

    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: During connection establishment, an access network and/or an access terminal may decide whether to transmit bearer-traffic data rather than null-traffic data based on a channel quality of a wireless link. For example, if the access network has forward bearer-traffic data ready for transmission to the access terminal during connection establishment, the access network may decide to transmit that forward bearer-traffic data rather than forward null-traffic data in response to determining that a forward-channel quality of the wireless link is sufficient to carry such data. As another example, if the access terminal has reverse bearer-traffic data ready for transmission to the access network during connection establishment, the access terminal may decide to transmit that reverse bearer-traffic data rather than reverse null-traffic data in response to determining that a reverse-channel quality of the wireless link is sufficient to carry such data.
