Abstract: An exemplary power control command (PCC) transmission scheme is disclosed. In a first aspect, an access terminal may decrease the rate at which to send PCCs directed to an access network in time periods during which a reverse noise on the wireless link over which the access terminal and access network are communicating is greater than a threshold value. In a second aspect, the access terminal may suspend transmission of a first type of PCCs (e.g., either “power up” or “power down” PCCs) directed to the access network in time periods during which the access network's forward transmission power to the access terminal is at boundary level. The exemplary PCC transmission scheme may thus enable the access terminal to decrease the amount of PCC data sent to the access network, which may in turn decrease the reverse noise on the wireless link and thereby improve reverse-link communication.

Abstract translation: 公开了一种示例性功率控制命令（PCC）传输方案。 在第一方面，接入终端可以在接入终端和接入网正在通信的无线链路上的反向噪声大于阈值的时间段内降低发送指向接入网络的PCC的速率 。 在第二方面，接入终端可以在接入网到接入终端的前向发射功率处于等待的时间段内暂停指向接入网的第一类型PCC（例如，上电或掉电PCC）的传输 边界水平。 因此，示例性PCC传输方案使得接入终端能够减少发送到接入网络的PCC数据的数量，这又可以减少无线链路上的反向噪声，从而改善反向链路通信。

Abstract: What is disclosed is a method of operating a wireless communication device. The method includes, when in a first mode of operation, transmitting an access request to a wireless access node at a first transmit power, starting a first countdown timer, and awaiting an access request acknowledge from the wireless access node. In the first mode of operation, if the access request acknowledge is received within the first countdown timer, the method includes halting the first countdown timer and awaiting a resource assignment message from the wireless access node, and if the access request acknowledge is not received within the first countdown timer, the method includes retransmitting the access request to the wireless access node at a second transmit power and restarting the first countdown timer. The method also includes receiving a control message to enter a second mode of operation from the wireless access node, and when in the second mode of operation, transmitting the access request to the wireless access node, starting a second countdown timer, and awaiting the resource assignment message from the wireless access node. In the second mode of operation, if the resource assignment message is received within the second countdown timer, the method includes halting the second countdown timer, and if the resource assignment message is not received within the second countdown timer, the method includes retransmitting the access request to the wireless access node and restarting the second countdown timer.

Abstract: An access terminal may be operating in a first mode in which it sends DSC transmissions that each indicate a cell in which the access terminal will be requesting data after sending the transmission. The access terminal may then detect that it is located at a boundary between two cells. In response, the access terminal may switch from operating in the first mode to operating in a second mode by reducing a number of timeslots that each DSC transmission occupies and beginning to alternate between sending a DSC transmission indicating the first cell and a DSC transmission indicating the second cell. In turn, the BTSs serving the two cells may receive these DSC transmissions and responsively switch from operating in a first mode to operating in a second mode in which both BTSs continue receiving the access terminal's data (e.g., by suspending the sending of “ForwardStopped” messages to an RNC).

Abstract: A method, system, and computer-readable media are provided for reducing mobile device roaming. A set of transition mobile-network attributes are captured by an idle mobile device before switching from a roaming network to a home network. A collection of transition mobile-network attributes are used to generate transition-based data. Active mobile-network attributes are compared to the transition-based data and used to recognize when the mobile device is within an area that can receive one or more services from the home network.

Abstract: In a communication system, a wireless access node receives an access request from a wireless communication device. In response, the access node starts an access timer and transfers signaling to the communication system indicating the access request. If the access timer expires before a response to the signaling is received, then the access node provides the wireless communication device with wireless access to the communication system. The access node receives the response to the signaling. If the response is negative and is received before the access timer expires, then the access node denies the access request. If the response is negative and is received after the access timer expires, then the access node terminates the wireless access to the communication system for the wireless communication device.

Abstract: 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.

Abstract: 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.

Abstract: Methods and systems for reducing the frequency of handoffs to non-preferred wireless coverage areas are presented. In particular, a RAN may determine that a WCD is likely to begin roaming. The WCD may be served by a preferred wireless coverage area and may be likely to roam to a non-preferred wireless coverage area. In order to avoid drawbacks associated with letting the WCD roam, the RAN may grant the WCD one or more forms of increased service quality. For example, the RAN may use a roaming-likelihood value as a basis for determining a page-concatenation level for the page, concatenate the page according to the determined page-concatenation level, and then transmit the page.

Abstract: 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.
