A method for configuring secondary component carriers associated with a service for a wireless device , the service being associated with a plurality of bearers, the method characterized by : receiving a message corresponding to the service (S122); and when the message is for establishing the service, then: determining a current number of secondary component carriers of the wireless device that are activated for a current service combination established for the wireless device (S18) (S124); determining an updated number of secondary component carriers for an updated combination of services for the wireless device , the updated combination including the service and the current service combination (S126); determining a number of additional secondary component carriers to activate for the updated service combination based on the updated number and current number of secondary component carriers (S128); and determining a maximum number of allowed secondary component carriers for the wireless device (S130); and when the updated number of secondary component carriers is greater than the current number of secondary component carriers (S132) but does not exceed the maximum number of allowed secondary component carriers of the wireless device (S134), then activating the number of determined additional secondary component carriers (S136). receiving a message corresponding to the service (S122); and when the message is for establishing the service, then: determining a current number of secondary component carriers of the wireless device that are activated for a current service combination established for the wireless device (S18) (S124); determining an updated number of secondary component carriers for an updated combination of services for the wireless device , the updated combination including the service and the current service combination (S126); determining a number of additional secondary component carriers to activate for the updated service combination based on the updated number and current number of secondary component carriers (S128); and determining a maximum number of allowed secondary component carriers for the wireless device (S130); and when the updated number of secondary component carriers is greater than the current number of secondary component carriers (S132) but does not exceed the maximum number of allowed secondary component carriers of the wireless device (S134), then activating the number of determined additional secondary component carriers (S136). determining a current number of secondary component carriers of the wireless device that are activated for a current service combination established for the wireless device (S18) (S124); determining an updated number of secondary component carriers for an updated combination of services for the wireless device , the updated combination including the service and the current service combination (S126); determining a number of additional secondary component carriers to activate for the updated service combination based on the updated number and current number of secondary component carriers (S128); and determining a maximum number of allowed secondary component carriers for the wireless device (S130); and when the updated number of secondary component carriers is greater than the current number of secondary component carriers (S132) but does not exceed the maximum number of allowed secondary component carriers of the wireless device (S134), then activating the number of determined additional secondary component carriers (S136). <EOS>
