    摘要: Methods and systems are provided for conducting power control based on reverse-link RF conditions. In an embodiment, a base station periodically calculates a reverse noise rise (RNR), periodically calculates a collective reverse-link frame error rate (RFER), and periodically checks whether a new call-origination message has been received. If a call origination has not been received, the base station checks whether the RNR is less than a threshold. If the RNR is less than the threshold, the base station sends power-up commands to each of mobile stations. If the RNR is not less than the threshold, the base station sends power-down commands to each of the mobile stations so long as the collective RFER is less than a maximum RFER. If a call origination has been received, the base station sends power-down commands to each of the mobile stations until the collective RFER reaches the maximum RFER.

    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: Methods and systems for adjusting a transmit power of a forward link or reverse link signal make use of variable adjustment parameters. The wireless signal is received to obtain a received signal. An observed signal-to-noise ratio (SNR) and an observed frame error rate (FER) for the received signal are determined. In an outer loop process, an adjustment increment is selected based on how much the observed FER differs from the target FER, and the target SNR is adjusted by the adjustment increment. In an inner loop process, a power adjustment command is selected based on a comparison between the observed SNR and a target SNR. The power adjustment command instructs the transmitter of the wireless signal to either increase or decrease the transmit power of the wireless signal. The power adjustment increment may also depend on the observed FER.

    摘要: A base station determines occupancy of a channel used for message communication and transmits channel occupancy data to access terminals operable to transmit messages via the channel. An access terminal receives characters for sending a text message via the channel and determines whether the channel occupancy exceeds an occupancy threshold. If the channel occupancy exceeds the threshold, the access terminal transmits characters of the text message to the base station via multiple messages. Each of those messages including a number of characters that does not exceed a maximum number of characters associated with the threshold. If the channel occupancy does not exceed the threshold, the access terminal transmits characters of the text message to the base station via a single message so long as the number of characters does not exceed a maximum number of characters for sending a complete text message to the base station via a single message.

    摘要: A method, system, and apparatus for managing spreading codes used in communication over a radio frequency air interface. When a radio access network (RAN) is to assign a spreading code to a mobile station in the coverage area, the RAN may determine which mobile station currently having an assigned traffic channel in the coverage area has a highest forward-link signal quality, and the RAN may select a spreading code based on the spreading code of that determined mobile station's assigned traffic channel. For instance, the RAN may select a spreading code that is quasi-orthogonal to the spreading code of the determined mobile station's assigned traffic channel.

    摘要: A method and system is disclosed for maintaining codec consistency across a communication session. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for network capacity variations spatially and/or temporally across the session. If the requested communication session is determined to be with a landline device, then a higher coding rate may be used than might otherwise be selected. If the requested session is with another AT, then a coding rate that best accommodates the air interfaces of both ATs may be used. If the AT is predicted to handoff to multiple sectors during the session, then a coding rate that best accommodates the air interfaces of all the predicted handoff sectors may be used.
