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, the method comprising:
- sending a first message to a network device, which first message comprises first configuration data configuring the network device to perform measurements in order to collect first information transmitted by network nodes in a surrounding area of the network device,receiving a first measurement report from the network device according to the first configuration,sending a second message to the network device configuring the network device to collect secondary information,receiving the secondary information from the network device,detecting the presence of a false base station based on a difference between the received secondary information and predetermined target information.

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.

15. A network node for use in detecting a false base station in a communications network, wherein the network node is configured to:
-
send a message to a network device, which message comprises configuration data for configuring the network device to perform measurements in order to collect information transmitted by network nodes in a surrounding area of the network device; receive a measurement report from the network device according to the configuration, wherein the measurement report comprises a physical cell identifier (PCI) that the network device determined from synchronization signals received by the network device, wherein the synchronization signals were transmitted by a base station; determine whether the base station is a false base station based on the PCI reported by the network device; and provide an indication that a false base station is present as a result of determining that the base station is a false base station. - View Dependent Claims (16)
