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： Methods and apparatus are provided for adjusting a forward-link power-control step size. An initial active set of coverage areas for a mobile station is maintained within which a first coverage area in the initial active set has a signal strength that is stronger than that of each of the other coverage areas in the initial active set. The first coverage area is determined to have dropped from the initial active set, resulting in a modified active set. In response, a signal-strength factor is calculated based on (a) a last non-zero signal-strength measurement of the first coverage area and (b) a second value. One or more forward-link power-control step sizes is selected based on at least the calculated factor. The one or more selected step sizes is used to increase the forward-link transmission power of at least one coverage area in the modified active set.

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： An access terminal in a coverage area of an access network may be monitoring a level of loading on the coverage area's reverse link, such as by monitoring a series of reverse activity bits sent by the access network. The access terminal may then detect new data for transmission to the access network and responsively select a reverse-link data rate based on the monitored level of loading. In this respect, the access terminal may select (a) a first data rate (e.g., a reverse-link data rate at which the access terminal last transmitted data) if the access terminal detects a low load, and (b) a second data rate (e.g., a minimum available reverse-link data rate) if the access terminal detects a high load, where the second data rate is lower than the first data rate. The access terminal may also consider its location in selecting the reverse-link data rate.

摘要： Methods and apparatus are provided for a wireless communication device (WCD) to utilize one or more search windows to capture both an earliest-received signal and a strongest received signal. In an embodiment, in a first time period, the WCD detects an arrival time of an earliest-received signal and an arrival time of a strongest received signal in one or more search windows for each of at least one set of signals. The WCD then centers a first search window based on the arrival time of the earliest-received signal and centers a second search window based on the arrival time of the strongest received signal for each of the at least one set of signals. In a second time period, the WCD searches for signals using the first and second search windows.

摘要： Methods for evaluating an access probe transmitted by a wireless communication device (WCD) in a wireless communication system are disclosed. When an access probe is received by a radio access network (RAN), the RAN determines if the WCD that transmitted the access probe is physically located outside a predetermined distance from the RAN. If the WCD is located outside the predetermined distance from the RAN, the RAN evaluates whether a threshold air interface condition is met as part of a determination to accept the access probe and establish communication between the RAN and the WCD.

摘要： A mobile station that is being served by a current sector receives a neighbor list that identifies a plurality of neighboring sectors and a respective priority for each neighboring sector. For each neighboring sector, the mobile station scans for the sector's pilot signal at a respective scanning frequency during a measurement interval. The scanning frequency for a sector defines how frequently the mobile station scans for the sector's pilot signal during the measurement interval. The mobile station selects a scanning frequency for a neighboring sector based on at least a signal strength of the current sector and the neighboring sector's priority. When the current sector's signal strength is high, the mobile station scans for high-priority sectors more frequently than low-priority sectors. When the current sector's signal strength is low, the mobile station scans for low-priority sectors more frequently than high-priority sectors.
