A wireless communication system (20) includes an ability to discern
whether an end of a communication link between a mobile station (22) and
a base station (26) corresponds to the mobile station (22) tuning away
from a first service to a second, different service. In a disclosed
example, a radio network controller (28) includes a link monitoring
portion that uses information regarding the mobile station from the
second service to determine a pattern of expected tune aways by the
mobile station to the second service. In one disclosed example, the link
monitoring portion uses observed mobile station behavior to estimate the
pattern of expected tune aways. Whenever an end of a communication link
with the mobile station corresponds to an expected tune away, that end is
not considered for purposes of service measurement parameters. The
disclosed examples provide the ability to avoid mistakenly considering a
mobile station-initiated tune away as a dropped link or handoff failure
resulting from an issue with the system.
