Abstract: 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.

Abstract: A method and medium are provided for changing operational parameters on a mobile device while the mobile device is roaming. The mobile device supplies data that indicates operational characteristics of the mobile device to a home network by sending a first short-message service (SMS) message to the home network. The mobile device is connected to a roaming network and thus, the first message is sent using the messaging services of the roaming network. The home network determines new operational parameters for the mobile device based on the data. The home network sends a second SMS message to the mobile device which delivered to the mobile device by the roaming network's messaging services. The mobile device receives the second SMS message at a designated control slot and changes stored operational parameters to the new operational parameters.

Abstract: A method and system is disclosed for dynamic adjustment of extended frame decoding interval duration based on signal-to-noise. In accordance with an example embodiment, upon determining that a frame transmission from an access terminal has not been successfully decoded during a nominal frame period, a base station will commence an extended decoding interval. The base station will also determine a duration for the extended decoding interval based on a measured signal-to-noise transmission power level from the access terminal. The base station will use the determined duration for the extended decoding interval. The determination will be made so as to increase the likelihood the extended decoding interval will result in a successful decoding of a frame of data.

Abstract: A method and corresponding system is provided for managing registrations and reducing registration failure. According to at least one embodiment of the method, a wireless communication device (WCD) receives a channel list message (CLM) in a given coverage area. The WCD may determine that it is not within coverage of a first channel specified in the CLM. The WCD may make this determination before attempting to register for service on the first channel. In response to making this determination, the WCD may register for service on another channel specified in the received CLM.

Abstract: A method and system is disclosed for dynamically adjusting a signal-to-noise (SNR) bias based on relative load between a macro type base station and a micro type base station of a wireless communication system. The SNR bias corresponds to a threshold differential SNR between SNRs of the macro base station and of the micro base station, wherein the SNR bias is configured to be provided to an access terminal (or user equipment) to cause the access terminal (i) to be biased to seek service from the micro base station if the access terminal detects an SNR from the micro base station that is less than the threshold differential SNR below an SNR that the access terminal detects from the macro base station, and (ii) to be biased to seek service from the macro base station otherwise. Once the SNR bias is determined based on the relative load, it is communicated to one or more access terminals.
