Abstract:
1. An apparatus comprising a processor configured to cause the apparatus: to control a first stand-alone base station utilizing a first radio access technology (RAT) to form an emulated first RAT cell and to set parameters of the emulated first RAT cell such that the emulated first RAT cell becomes a tempting destination for a cell reselection by a subscriber terminal having an ongoing radio connection with a serving cell base station belonging to a cellular radio system and utilizing the first RAT; to control a second stand-alone base station utilizing a second RAT to form an emulated second RAT cell and to set parameters of the emulated second RAT cell such that the emulated second RAT cell becomes a preferred destination for a cell reselection; to control the first stand-alone base station utilizing the first RAT to perform cell reselection with the subscriber terminal so that the ongoing radio connection with the serving cell base station utilizing the first RAT is transferred to continue with the first stand-alone base station utilizing the first RAT; and to control the first stand-alone base station utilizing the first RAT and the second stand-alone base station utilizing the second RAT to perform inter RAT cell reselection with the subscriber terminal so that the ongoing radio connection with the first stand-alone base station utilizing the first RAT is transferred to continue with the second stand-alone base station utilizing the second RAT; wherein the processor is further configured to cause the apparatus to control a third stand-alone base station utilizing the second RAT to interfere a first frequency band of the serving cell base station utilizing the first RAT, on which first frequency band the subscriber terminal is having the ongoing radio connection with the serving cell base station utilizing the first RAT.
