Abstract

The number of signal bars displayed during a wireless telephone call does not necessarily correlate with user experience. The number of signal bars displayed is based on available signal strength for the user’s cellular device. However, it fails to account for other network parameters that govern call quality. For example, one participant device of a wireless phone call may have excellent signal strength but poor call quality because the other end has poor signal strength.

Techniques of this disclosure describe an improved call quality indicator that is based on signal conditions on both sides of a call, as well as QoS-related network parameters such as packet delay, packet loss, jitter, call-drop status, etc. By incorporating remote side call quality, the resulting call quality metric is a more accurate reflection of user experience.
