NETWORK NODE AND METHOD FOR DETECTING FALSE BASE STATIONS

摘要

A method performed by a network node (101), for detecting a false base station in a communications network (100). The network node (101) operates in the communication network (100) and is adapted to serve a network device (120) via a serving Radio Access, RA, node (110). The network node (110) sends a message to a network device (120), which message comprises configuration data configuring the network device (120) to perform measurements in order to collect information transmitted by network nodes (110) in a surrounding area of the network device (120). The network node (110) further receives a message comprising measurement reports from the network device (120) according to the configuration. The network node (110) further provides an indication that a false base station is present when a difference between the received information in the measurement report and a predetermined target information is detected.
