Abstract

A measurement method and device for wireless network communication system is disclosed. The method enables operators to use recording information to detect whether there is any problem in network and to perform some necessary optimizing work by enabling user equipment (UE) to automatically record some measurement logs and to periodically report them to the network. Because the information is automatically collected by the UE, the method effectively reduces the workload and cost devotion which is needed for network measurement by manual road measurement. The method enables the operators to obtain measurement information of geography areas that can not be obtained in ordinary road measurement because the UE is randomly distributed at any position in the network.
