摘要： Disclosed is a method and apparatus to manage selection of a paging channel in a wireless communication system. When a mobile station powers on in a coverage area having multiple paging channels, the mobile station may apply a hashing algorithm keyed to the mobile station's identifier, to select a paging channel on which to idle. On the other hand, when the mobile station moves from a coverage area having a number of paging channels into a neighboring coverage area having a different number of paging channels, the mobile station may by rote idle on a default paging channel in the neighboring coverage area. In this way, the mobile station can help to avoid an access handoff failure that may arise from the mobile station being busy hashing onto a paging channel when the network transmits an access response message to the mobile station.

摘要： Disclosed is a method and device for managing handoff of an access terminal in a radio access network (RAN). An access terminal may detect a handoff trigger, determine whether there is an ongoing data transfer in progress, determine an amount remaining in the data transfer, compare the amount remaining to a threshold amount, and delay or cancel the handoff if the amount remaining is below the threshold amount. Additionally, the access terminal may consider signal strength of the current (source) coverage area in determining whether to delay or cancel the handoff.

摘要： Methods and apparatus are provided for dynamically adjusting a search-window size. An active-call state is entered into, and a mobile station is responsively initially operated according to a default-search-window mode. The preferred-signal strength as received at the mobile station, the preferred-signal fading of the mobile station, and the number of sectors in an active set for the mobile station are monitored to: compare the preferred-signal strength to a signal-strength threshold, compare the preferred-signal fading to at least one of a lower-fading threshold and an upper-fading threshold, and determine whether the number of sectors in the active set is exactly one sector or more than one sector. The mobile station is selectively operated in one of the default-search-window mode, a reduced-search-window mode, and an increased-search-window mode in response to the monitored preferred-signal strength, preferred-signal fading, and number of sectors in the active set.

摘要： A wireless communication link (a forward link or a reverse link) between a base station and a mobile station may be power-controlled to reduce a difference between an observed error rate in communications received over the link and a target error rate. The target error rate may be dependent upon the radio frequency (RF) conditions at the mobile station, which may be determined by measuring a signal strength of a pilot signal transmitted by the base station. Thus, a pilot signal strength at the mobile station may be determined, a target error rate may be selected based on the pilot signal strength, and the target error rate may be used to control a transmit power level of the wireless communication link. A mobile station may power-control a forward link and/or a base station may power-control a reverse link using a target error rate selected in this way.

摘要： An access terminal may be requesting from an access network data in a first coverage area at a first data rate, which is determined based on at least one signal condition of the first coverage area. The access terminal may then decide to switch from requesting data in a first coverage area to requesting data in a second coverage area. In response, the access terminal may (a) request data in the first coverage area at an increased second data rate and (b) send to the access network a notification of the decision to switch from requesting data in a first coverage area to requesting data in a second coverage area. After sending the notification, the access terminal may request data in the second coverage area at a third data rate, which is determined based on at least one signal condition of the second coverage area.

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： A method and system is disclosed for dynamic adaptation of reverse-link power control based on the distribution of ATs implementing different protocol versions. An access terminal in a wireless communication system that includes a base station may operate in a first state in which, at least, the access terminal uses a first protocol for determining and adjusting transmission power on a reverse link of an air interface with the base station. While operating in the first state, responsive to receiving a protocol version message from the base station on a forward link of the air interface, the access terminal will transition to operating in a second state in which, at least, the access terminal uses a second protocol for determining and adjusting transmission power on the reverse link of the air interface with the base station. The first protocol is different from the second protocol.

摘要： A method and system is disclosed for shifting the phase of a PN long code for access attempts by an access terminal in a wireless communication network. An access terminal may seek to acquire access from a base station that is detected by the access terminal above a threshold power level, even if the access terminal is further away from the base station than a threshold distance beyond which access is not normally granted. According to one embodiment, the access terminal will, upon determining that it is beyond the threshold distance, embed in an access request message an apparent distance that is smaller than the threshold distance, by phase-shifting a timing signal and encoding the access request message with the phase-shifted timing signal. The access terminal will then transmit the access request message on an air interface communication link to the base station.

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.
