Abstract
A method performed in a network node for identifying UEs which are non-compliant with modified CRS operation. The network node enables CRS operation according to a first configuration for a first period. The network node analyzes Information Elements (IE) in RRC Connection Re-establishment Request messages received from UEs during the first period. The network node generates a first set containing identities of UEs whose values in reestablishmentCause IE in the RRC Connection Re-establishment Request messages received during the first period are 'otherFailure'. When the first period is finished, the network node enables CRS operation according a second configuration different from the first configuration for a second period. The network node analyzes IE in RRC Reestablishment Request messages received from UEs during the second period. The network node generates a set containing identities of non-compliant UEs based on the first set and analyzing IE in the RRC Reestablishment Request messages received during the second period.
