Adaptive out of service scanning

摘要

A method for selecting an out of service (OOS) scan mode for a wireless communication device is provided. The method can include the wireless communication device detecting occurrence of an OOS condition; setting a displacement threshold in response to the OOS condition; determining a displacement magnitude indicative of a distance traveled by the wireless communication device during the OOS condition; determining whether the displacement magnitude exceeds the displacement threshold; using a first scan mode to scan for network coverage in an instance in which it is determined that the displacement magnitude exceeds the displacement threshold; and using a second scan mode to scan for network coverage in an instance in which it is determined that the displacement magnitude does not exceed the displacement threshold. The first scan mode can have a greater scan frequency than the second scan mode.

1. A method for selecting an out of service (OOS) scan mode for a wireless communication device, the method comprising:
by the wireless communication device: detecting occurrence of an OOS condition; setting a displacement threshold in response to the OOS condition; determining a first displacement magnitude indicative of a distance traveled by the wireless communication device at a first time during the OOS condition; determining whether the first displacement magnitude exceeds the displacement threshold; using a first scan mode to scan for network coverage in an instance in which it is determined that the first displacement magnitude exceeds the displacement threshold; and in an instance in which it is determined that the first displacement magnitude does not exceed the displacement threshold:
using a second scan mode to scan for network coverage;determining a second displacement magnitude indicative of the distance traveled by the wireless communication device at a second time during the OOS condition, the second time being a defined time subsequent to the first time;determining whether the second displacement magnitude exceeds the displacement threshold;switching to the first scan mode to scan for network coverage in an instance in which the second displacement magnitude exceeds the displacement threshold; andcontinuing to use the second scan mode to scan for network coverage in an instance in which the second displacement magnitude does not exceed the displacement threshold,wherein the first scan mode has a greater scan frequency than the second scan mode.
