    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 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: 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. In one example, a target error rate of the first reverse link signal and a maximum transmit power level of the second forward link signal are selected based on the receiver sensitivity of the 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.

    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 radio access network (RAN) receives a request to route a call from a caller to a mobile station, assigns a wireless traffic channel to the mobile station for the call, and detects a no-answer condition for the call (because a user of the mobile station does not answer the call within a predetermined time period or has chosen to ignore the call). In response to the no-answer condition, the RAN redirects the call to a voice mail system and keeps the wireless traffic channel assigned to the mobile station while the caller interacts with the voice mail system. The RAN determines that the caller has left a voice mail message on the voice mail system and transmits an indication of the voice mail message to the mobile station over the wireless traffic channel.
