摘要： Disclosed herein is a method and system for providing multiple reverse-activity bits (RABs) in a coverage area. An exemplary method involves (a) providing EV-DO service in a wireless coverage area; (b) measuring reverse noise rise (RNR) in the wireless coverage area; (c) comparing the measured RNR to each of a plurality of RNR thresholds, wherein each RNR threshold corresponds to one of a plurality of RABs; (d) using the RNR threshold corresponding to each RAB as compared to the measured RNR as a basis for determining whether to set or clear the particular RAB; and (e) providing the plurality of RABs in the wireless coverage area.

摘要： Disclosed is a method and system for allocating power among concurrent transmission attempts from a radio access network (RAN). In practice, the RAN encounters a situation where the RAN is going to engage concurrently in at least a transmission attempt of a first message and a transmission attempt of a second message. The RAN then determines an attempt number of the first transmission attempt and an attempt number of the second transmission attempt. The RAN then compares the determined attempt numbers and, based on the comparison, allocated a limited quantity of transmission power among the first transmission attempt and the second transmission attempt. For instance, based the comparison a greater portion of the transmission power may be allocated to one of the transmission attempts and a correspondingly lesser portion of the transmission power may be allocated to the other transmission attempt.

摘要： Methods and systems are provided for overriding a most-recently-used (MRU) table for system acquisition. In an embodiment, a mobile station maintains an MRU table populated with data identifying one or more networks to which the mobile station was most recently connected, and the mobile station is arranged to conduct system acquisition by referencing the MRU table prior to referencing a preferred roaming list (PRL). The mobile station receives an MRU-override instruction from a wireless network, and modifies its MRU table according to the instruction, producing a modified MRU table, and conducts at least one subsequent system acquisition with reference to the modified MRU table.

摘要： Methods and systems are provided for selectively conducting reverse-link power control and call admission control. In an embodiment, a base station identifies a set of mobile stations more likely than others to experience a dropped call. For each mobile station in the set, the base station relaxes at least one reverse-link power-control setting, to foster an increased actual and/or allowed reverse-link transmission-power level. The base station thereafter detects the dropped-call rate exceeding a first threshold, and responsively decreases the degree to which at least one setting was relaxed. The base station thereafter detects the dropped-call rate exceeding a higher threshold, and responsively drops at least one active call and/or blocks at least one new call.

摘要： A radio access network (RAN) allocates a resource, such as a forward traffic channel, to a mobile station that is engaged in a call. During the call, the RAN monitors a reverse link signal that is received from the mobile station. If the RAN detects a reception failure, such as the receipt of an errored frame in the reverse link signal, the RAN determines the power level that the mobile station used to transmit the reverse link signal when the reception failure occurred. If the mobile station was already transmitting at its maximum power level, the RAN may immediately release the resource. Otherwise, the RAN defines a test period that is sufficient for the mobile station to increase its transmit power to the maximum level. If the reception failure continues throughout the test period, the RAN may then release the resource.

摘要： A method is disclosed for disambiguating a reported pilot signal so as to facilitate handoff of a mobile station. When a radio access network (RAN) receives from a mobile station a handoff request carrying a parameter that ambiguously identifies at least two sectors as the potential handoff target, the RAN will send a test probe on at least one of the potential handoff target sectors and will determine, based on mobile station response to the test probe, which sector the mobile station received the test probe on and thus which sector was the intended handoff target. The RAN may then direct the mobile station to hand off to that sector if appropriate. Further, the RAN may add the identified sector into a neighbor list of a similarly situated other mobile station, to allow the other mobile station to more efficiently hand off to the same sector if appropriate.

摘要： A mobile station and a radio access network (RAN) use a single-channel forward link and a single-channel reverse link for a communication session. If the quality of the communication session degrades, the single-channel forward link is replaced with a multi-channel forward link and/or the single-channel reverse link is replaced with a multi-channel reverse link. The multi-channel forward link may include a first forward link channel and a second forward link channel, each with a higher coding gain than that of the single-channel forward link, to provide an aggregate data rate that is substantially the same as that of the single-channel forward link. The multi-channel reverse link may include a first reverse link channel and a second reverse link channel, each with a higher coding gain than that of the single-channel reverse link, to provide an aggregate data rate that is substantially the same as that of the single-channel reverse link.

摘要： Methods and apparatuses are provided for identifying and selectively controlling reverse-noise contribution on a per-access terminal basis. In an embodiment, an access node provides wireless service to access terminals, and measures reverse noise rise (RNR) during at least one turn of a round-robin process involving access terminals taking turns transmitting data or taking turns not transmitting data. The access node thereby determines a respective RNR contribution of at least one access terminal based at least on the measurement of RNR taken during the access terminals' turns. A high-contributor set of one or more access terminals is identified and then instructed to reduce reverse-link transmission power.

摘要： Disclosed are methods for determining which page attempt to shed. In accordance with these methods, when a page attempt from a first sequence directed to a first access terminal (AT) contends with a page attempt from a second sequence directed to a second AT for transmission over the air interface of a RAN, the RAN determines which sequence has been shed to a greater extent. The RAN then transmits the page attempt from the sequence that has been shed to a greater extent and sheds the page attempt from the sequence that has been shed to a lesser extent. The methods advantageously help to avoid one sequence of page attempts being disproportionately shed.

摘要： Disclosed herein is a method for repeat paging in a wireless communication system. In accordance with the method, a RAN controller will send a repeat-paging directive to a plurality of BTSs to cause each BTS to begin broadcast of a series of page messages destined to a target mobile station. While transmitting the series, one of the BTSs will then receive from the mobile station a page response, and the BTS will responsively provide to the RAN controller a notification of the page response. In response to receipt of the notification, the RAN controller will then send a paging-stop directive to at least each other BTS of the plurality, and each BTS that receives the paging-stop directive will responsively discontinue broadcasting the series of page messages before completing broadcast of the entire series of page messages, thereby helping to conserve air interface resources.
