The method comprises: continuously receiving by vehicle's telematic system a predictive model generated by remote system using data continuously collected from a plurality of vehicles, wherein the collected data comprise, for each given vehicle of the plurality of vehicles, data informative of its location, speed and of Radio Access Technology (RAT)-related measurements; and, responsive to a predefined event, applying, by the telematic system, a lastly received predictive model to current values of a predefined set of inputs associated with the vehicle to obtain instructions and respectively provide corrective actions related to radio connectivity of the vehicle. The corrective actions include modifying RRC measurement report(s) so as to force the cellular network to provide one of: intra-RAT handover, inter-RAT handover; excluding available connectivity with undesired RAT or band; and terminating the radio connectivity with further RAT re-selecting. ## Claims ### Claim 1 A method of operating a vehicle telematic system operatively connected to a cellular network characterized by one or more Radio Access Technologies (RAT), the method comprising: continuously obtaining by the telematic system data indicative of current values of a predefined set of inputs associated with the vehicle, the predefined set of inputs comprising location of the vehicle, speed of the vehicle, a currently activated leading communication-related service and RAT-related measurements provided by the vehicle; and responsive to a predefined event, using the obtained data indicative of current values of the predefined set of inputs to modify by the telematic system one or more radio resource control (RRC) measurement reports and sending the modified one or more RRC measurement reports to the cellular network, wherein the RRC measurement reports are modified to enable one or more actions selected from a group consisting of: i. forcing the cellular network to provide intra-RAT handover or inter-RAT handover; ii. forcing the cellular network to exclude available connectivity with undesired RAT or band; iii. forcing the cellular network to terminate radio connectivity with the telematic system and to enable automatic RAT reselecting. ### Claim 2 (depends on 1) The method of claim 1, wherein the predefined set of inputs further comprises data informative of Service Level Agreement (SLA) violation or near SLA violation for the currently activated leading service. ### Claim 3 (depends on 1) The method of claim 1, wherein the predefined event is selected from the group consisting of changes of RAT and/or band characterizing radio connectivity of the vehicle, activation/deactivation of a communication-related service provided to the vehicle, change of a location bin, SLA violation and near SLA violation for the currently activated leading service. ### Claim 4 A vehicle telematic system to manage radio connectivity of a vehicle, the telematic system operating a vehicle telematic system operatively connected to a cellular network characterized by one or more Radio Access Technologies (RAT) and comprising a processor and memory circuitry (PMC), wherein the PMC is configured to: continuously obtain data indicative of current values of a predefined set of inputs associated with the vehicle, the predefined set of inputs comprising location of the vehicle, speed of the vehicle, a currently activated leading communication-related service and RAT-related measurements provided by the vehicle; and responsive to a predefined event, use the obtained data indicative of current values of the predefined set of inputs to modify by the telematic system one or more radio resource control (RRC) measurement reports and send the modified one or more RRC measurement reports to the cellular network, wherein the RRC measurement reports are modified to enable one or more actions selected from a group consisting of: i. forcing the cellular network to provide intra-RAT handover or inter-RAT handover;
