Claim Text:
1. A method, implemented in a user equipment of a communication network, for reporting inter-radio access technologies measurements, the communication network comprising a first radio access technology system and a second radio access technology system, the user equipment being simultaneously connected to and served by a primary serving cell of the first radio access technology system via a primary carrier and a secondary serving cell of the second radio access technology system via a secondary carrier, the method comprising: performing signal strength measurements on the primary carrier of the first radio access technology system; performing signal strength measurements on the secondary carrier of the second radio access technology system; wherein the first radio access technology system controls both the connection between the user equipment and the primary serving cell of the first radio access technology system and the connection between the user equipment and the secondary serving cell of the second radio access technology system; determining, based on the corresponding signal strength measurements, whether a criterion for a measurement event is fulfilled, the criterion relating to a serving cell change of the second radio access technology system or relating to a change of a primary radio access technology system; in response to the criterion being fulfilled, transmitting a corresponding measurement report to the communication network by transmitting a measurement related to the second radio access technology system to the first radio access technology system.
