Coverage determining method for digital trunked system, involves transmitting data associated with mobile interruptions to evaluating unit of mobile network after receiving corresponding request from evaluating unit

摘要

The method involves storing data by a part of a mobile subscriber (MT), where the data is used for determining position of the mobile subscriber using satellite navigation devices. The data is associated with mobile interruptions, and an error of a signal to mobile systems (BS1-BS3) and/or non-establishment of a connection to the mobile systems are detected as the mobile interruptions. The data associated with the mobile interruptions is transmitted to an evaluating unit of a mobile network after receiving a corresponding request from the evaluating unit.
