Abstract
Systems and methods for maintaining time stamping accuracy are disclosed. In one embodiment, a wireless device in a cellular communications network logs data to provide a log. The wireless device maintains an accuracy of time stamping for the log to meet, or satisfy, a non-linear time drift constraint. In one embodiment, the log is one or more of a Radio Resource Control (RRC) connection establishment failure log, a radio link failure log, a random access failure log, a paging channel failure log, a broadcast channel failure log, data related to failure of one or more specific channels, and a radio measurement. In another embodiment, the log is a Minimization of Drive Tests (MDT) log.
