A mobile terminal device comprising a first subscriber identity module, SIM, (SIMA), a second SIM (SIMB), a radio processing circuit and a baseband processing circuit configured to interact with the radio processing circuit, the baseband processing circuit configured to: identify one or more first inter-radio access technology, inter-RAT, measurement targets of a first radio measurement of a master RAT of the first SIM (SIMA); obtain one or more previously reported measurement results for one or more second inter-RAT measurement targets of a second radio measurement of the second SIM (SIMB) measured prior to identifying the one or more first inter-RAT measurement targets of the first radio measurement of the first SIM (SIMA); compare the one or more first inter-RAT measurement targets of the first radio measurement of the first SIM (SIMA) to the one or more second inter-RAT radio measurement targets for the second SIM (SIMB) to identify common measurement targets; identify one or more common measurement results from one or more measurement results of the second radio measurement of the second SIM (SIMB), wherein at least one of the one or more common measurement results corresponds to a common measurement target of the one or more first inter-RAT measurement targets of the first radio measurement and the one or more second inter-RAT measurement targets of the second radio measurement; provide the one or more common measurement results to the first radio measurement as one or more inter-RAT measurements results of the first radio measurement for the first SIM (SIMA); perform a subsequent radio measurement for the second SIM (SIMB) for any of the one or more first inter-RAT remaining measurement targets not provided by the previously reported measurement results; provide one or more measurement results from subsequent radio measurement of the second SIM (SIMB) for any of the one or more first inter-RAT remaining measurement targets to the first SIM (SIMA); and perform mobility operations with the one or more measurement results of the first radio measurement of the first SIM (SIMA) or the one or more measurement results of the second radio measurement of the second SIM (SIMB). identify one or more first inter-radio access technology, inter-RAT, measurement targets of a first radio measurement of a master RAT of the first SIM (SIMA); obtain one or more previously reported measurement results for one or more second inter-RAT measurement targets of a second radio measurement of the second SIM (SIMB) measured prior to identifying the one or more first inter-RAT measurement targets of the first radio measurement of the first SIM (SIMA); compare the one or more first inter-RAT measurement targets of the first radio measurement of the first SIM (SIMA) to the one or more second inter-RAT radio measurement targets for the second SIM (SIMB) to identify common measurement targets; identify one or more common measurement results from one or more measurement results of the second radio measurement of the second SIM (SIMB), wherein at least one of the one or more common measurement results corresponds to a common measurement target of the one or more first inter-RAT measurement targets of the first radio measurement and the one or more second inter-RAT measurement targets of the second radio measurement; provide the one or more common measurement results to the first radio measurement as one or more inter-RAT measurements results of the first radio measurement for the first SIM (SIMA); perform a subsequent radio measurement for the second SIM (SIMB) for any of the one or more first inter-RAT remaining measurement targets not provided by the previously reported measurement results; provide one or more measurement results from subsequent radio measurement of the second SIM (SIMB) for any of the one or more first inter-RAT remaining measurement targets to the first SIM (SIMA); and perform mobility operations with the one or more measurement results of the first radio measurement of the first SIM (SIMA) or the one or more measurement results of the second radio measurement of the second SIM (SIMB).
