Abstract: In various embodiments, a wireless device processor may determine a threat score for a first cell, determine whether the first cell threat score is below a first threat score threshold, update a good neighbor cell data structure using neighbor cell information from the first cell in response to determining that the first cell threat score is below the first threat score threshold, performing cell reselection to a second cell, determine whether the second cell transmits a system information block message indicating fake neighbor cell information, and increase a threat score for the second cell in response to determining that the second cell provides the SIB message indicating fake neighbor cell information and that a good neighbor cell data structure includes an indication of one or more good neighbor cells that are within the time threshold and the location threshold and doing countermeasures in a response to the determination.
