Have
you ever missed a call on your mobile device even though you were in an area
with sufficient network coverage? Failed mobile terminated calls (MTC) often
lead to customer complaints because a subscriber’s device appears to have
sufficient signal strength, yet they have problems receiving incoming calls.
This presentation explains how a MTC is typically established and outlines a process for
collecting and analyzing data to better understand why these calls can
sometimes fail. Results from collecting data on a commercial network
implementation are presented and explained in detail.
Wireless network
operators can use the methods described in this paper to guide them through the
process of collecting and analyzing data around MTC failures, ultimately
helping them to improve quality of service for their subscribers.
