System and method for communicating with an optimal wireless communications carrier
First Claim
1. A wireless device, comprising:
- a transceiver configured to transmit and receive communications signals;
a processor in communication with said transceiver,a memory in communication with said processor and configured to store a preferred roaming list containing information associated with communications carriers arranged in a predetermined order and a signal strength threshold value indicative of a communications signal being a marginal communications signal by the communications signal being received by said transceiver having a signal strength value below the signal strength threshold value; and
a plurality of software modules executed by said processor, including;
a timer module configured to define a time interval that specifies how often a signal search module executes;
a signal strength measurement module configured to measure signal strength of a communications signal received by said transceiver; and
the signal search module configured to;
determine that the signal strength of a first communications signal of a first communications carrier currently being received by said transceiver is a marginal communications signal;
select a second communications carrier in the preferred roaming list positioned in a first direction from the position in the preferred roaming list of the first communications carrier having a second communications signal with a higher signal strength than the signal strength of the first communications signal; and
switching said transceiver from receiving the first communications signal to receive the second communications signal from the second communications carrier in response to determining that the first communications signal is a marginal communications signal.

Abstract
Improvement of wireless communications of a wireless device may include storing a preferred roaming list containing information associated with communications carriers arranged in a predetermined order. It maybe determined that a signal strength of a first communications signal of a first communications carrier currently being received by a wireless device drops below a signal strength threshold value. A second communications carrier in the preferred roaming list having a second communications signal with a higher signal strength than the signal strength of the first communications signal may be selected. A time interval over which to receive the second communications signal from the second communications carrier may be initiated and a switch may occur from receiving the second communications signal from the second communications carrier to receiving a third communications signal from a communications carrier in the preferred roaming list in response to completion of the time interval.
