摘要： Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.

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 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.

摘要： Methods and computer-readable media are provided to enable the selection of a cell tower sector that is used by the mobile device to provide higher quality signals in a current frame. Signal quality data is retrieved for a previous quantity of frames, and indicates the signal quality of signals communicated from multiple sectors to a mobile device during soft handoff. A sector that has been communicating higher quality signals is then selected. Loading, signal-to-noise ratio, and a number of traffic channels may be used independently or in conjunction to determine which sector to select. For time slots of a current frame, an overall power control command is communicated to each sector that corresponds to a power control command assigned to the selected sector.

摘要： An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

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 computer-readable media are provided to determine which sector the mobile device will bias during soft handoff. Signals are received from multiple sectors, and for a first quantity of time slots of a frame, the signals are inspected to determine whether a quality threshold is met. Based on whether the quality threshold is met, each sector is assigned a power control command indicating that either a decrease or increase of output power is recommended when a subsequent signal is sent to the mobile device. For a second quantity of time slots, the overall power control command sent to the sectors corresponds to the power control command assigned to the sector that has communicated the highest quality signals for the first quantity of time slots of the frame.

摘要： During a communication session, a first BTS transmits a first forward link signal that is received by a first mobile station, a second BTS transmits a second forward link signal that is received by a second mobile station, the first mobile station transmits a first reverse link signal that is received by the first BTS, and the second mobile station transmits a second reverse link signal that is received by the second BTS. One or more control parameters for the forward and/or reverse link signals are selected based on a receiver sensitivity of the first mobile station and/or second mobile station.

摘要： Methods and systems for adaptive hybrid automatic repeat request (H-ARQ) protocols are disclosed. The protocols preferably adapt to changing network conditions between a client node and an access node by omitting the transmission of certain messages when network conditions are determined to be favorable. In doing so, packets are processed faster, thus reducing communication latency as well as the memory requirements of the protocols. One scenario in which the protocols may operate is where the client node is a wireless communication device coupled to the access node via a wireless network. In such a scenario, the access node may, from time to time, measure a quality of the wireless air interface between the client node and the access node, and determine whether to transmit an acknowledgement message based on the outcome of the measurement as compared to a threshold value.

摘要： An access network may receive an incoming communication for an idle access terminal having a last-known location in a first service area of the access network. In response to receiving the incoming communication, the access network may determine whether the last-known location is proximate to a border between the first service area and a second service area of the access network. If so, the access network may define a border paging area encompassing one or more coverage areas within the second service area that are proximate to the last-known location. In turn, the access network may determine a representative paging-channel occupancy of the border paging area. Based on the representative paging-channel occupancy, the access network may then select a time at which to initiate a border page of the access terminal in the border paging area and then perhaps initiate the border page at the selected time.
