NETWORK NODE AND METHOD FOR DETECTING FALSE BASE STATIONS
First Claim
1. A method performed by a network node, for detecting a false base station in a communications network, which network node operates in the communication network and wherein the network node is adapted to serve a network device via a serving Radio Access, RA, node, characterized in that the method comprises:
- sending a message to a network device, which message comprises configuration data configuring the network device to perform measurements in order to collect information transmitted by network nodes a surrounding area of the network device,receiving a message comprising measurement reports from the network device according to the configuration,providing 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.

Abstract
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.
