A mobile communication device, comprising: a wireless transceiver, configured to perform wireless transmission and reception to and from a service network; and a controller, configured to: receive (S310, S320) a cell information list containing priority levels of cells; determine whether an Application-specific Congestion control for Data Communication, ACDC, for a Long Term Evolution, LTE, based technology has been enabled or not in the cells taken one by one from the highest priority cell to the least priority cell according to the cell information list, by receiving system information from the cells until one of the cells has been determined to have ACDC not enabled or until all of the cells have been determined to have ACDC enabled (S360, S370); in response to the ACDC for the LTE-based technology not having been enabled in one of the cells, select or reselect to the cell, in which the ACDC for the LTE-based technology has not been enabled, via the wireless transceiver; and in response to the ACDC for the LTE-based technology having been enabled in all of the cells, select or reselect to one of the cells, which has the highest ACDC category among the cells, according to the system information via the wireless transceiver. a wireless transceiver, configured to perform wireless transmission and reception to and from a service network; and a controller, configured to: receive (S310, S320) a cell information list containing priority levels of cells; determine whether an Application-specific Congestion control for Data Communication, ACDC, for a Long Term Evolution, LTE, based technology has been enabled or not in the cells taken one by one from the highest priority cell to the least priority cell according to the cell information list, by receiving system information from the cells until one of the cells has been determined to have ACDC not enabled or until all of the cells have been determined to have ACDC enabled (S360, S370); in response to the ACDC for the LTE-based technology not having been enabled in one of the cells, select or reselect to the cell, in which the ACDC for the LTE-based technology has not been enabled, via the wireless transceiver; and in response to the ACDC for the LTE-based technology having been enabled in all of the cells, select or reselect to one of the cells, which has the highest ACDC category among the cells, according to the system information via the wireless transceiver. receive (S310, S320) a cell information list containing priority levels of cells; determine whether an Application-specific Congestion control for Data Communication, ACDC, for a Long Term Evolution, LTE, based technology has been enabled or not in the cells taken one by one from the highest priority cell to the least priority cell according to the cell information list, by receiving system information from the cells until one of the cells has been determined to have ACDC not enabled or until all of the cells have been determined to have ACDC enabled (S360, S370); in response to the ACDC for the LTE-based technology not having been enabled in one of the cells, select or reselect to the cell, in which the ACDC for the LTE-based technology has not been enabled, via the wireless transceiver; and in response to the ACDC for the LTE-based technology having been enabled in all of the cells, select or reselect to one of the cells, which has the highest ACDC category among the cells, according to the system information via the wireless transceiver.
