US 9,521,702 B2 · Method and apparatus for scanning amongst two-way radios

Abstract

A method and apparatus for scanning amongst two-way radios is disclosed. The method includes applying a scan probability index (SPI) to each member of a scan list, the SPI indicating a likelihood of channel activity. The SPI is dynamically updated by a variety of processes. Members are loaded from the scan list, and the SPI of the loaded member is compared to a threshold. Members are skipped or checked for activity based on the SPI passing or failing the threshold. Members having a sufficient SPI will proceed to have detected channel activity decoded. The method and apparatus may utilize both normal scan members and vote scan member frequencies.

Dependent claims

A method for radio scanning, the method comprising:

applying a scan probability index (SPI) to each member of a scan list, the SPI indicating a likelihood of channel activity, wherein the SPI depends upon scan list member type, detected activity, and available coverage areas;
loading a member from the scan list;
determining the SPI for the loaded member;
comparing the SPI to a predetermined SPI threshold;
skipping the member and loading a new member from the scan list in response to the SPI failing to meet the predetermined SPI threshold;
checking for channel activity in response the SPI meeting the predetermined SPI threshold;
skipping the member and loading a new member from the scan list in response to channel activity not being detected;
and
decoding the channel activity in response to the channel activity being detected.
