A method for processing a Multimedia Broadcast Multicast Service, MBMS, comprising: receiving, by a network side, from a User Equipment, UE, information about an MBMS service that the UE is interested in; determining, by the network side, whether the UE has a Carrier Aggregation, CA, capability; when the network side determines that the UE has the CA capability, determining, by the network side, whether the UE supports receiving the MBMS service on a Secondary Cell, SCell, in the serving cell; when the network side determines that the UE has the CA capability and that the UE supports receiving the MBMS service on the Scell in the serving cell, determining, by the network side, whether the frequency corresponding to the MBMS service that is of interest to the UE is the frequency of the serving cell of the UE; when the network side determines that the frequency corresponding to the MBMS service that is of interest to the UE is not the frequency of the serving cell of the UE, determining, by the network side, whether the frequency combination supported by the UE has been activated completely, when the network side determines that the frequency combination supported by the UE has been activated completely, deactivating, by the network side, one SCell of the frequency combination and activating thereafter, by the network side, the frequency corresponding to the MBMS service that is of interest to the UE; and when the network side determines that the frequency combination supported by the UE has not been activated completely, activating, by the network side, the frequency corresponding to the MBMS service that is of interest to the UE as the frequency corresponding to the SCell. receiving, by a network side, from a User Equipment, UE, information about an MBMS service that the UE is interested in; determining, by the network side, whether the UE has a Carrier Aggregation, CA, capability; when the network side determines that the UE has the CA capability, determining, by the network side, whether the UE supports receiving the MBMS service on a Secondary Cell, SCell, in the serving cell; when the network side determines that the UE has the CA capability and that the UE supports receiving the MBMS service on the Scell in the serving cell, determining, by the network side, whether the frequency corresponding to the MBMS service that is of interest to the UE is the frequency of the serving cell of the UE; when the network side determines that the frequency corresponding to the MBMS service that is of interest to the UE is not the frequency of the serving cell of the UE, determining, by the network side, whether the frequency combination supported by the UE has been activated completely, when the network side determines that the frequency combination supported by the UE has been activated completely, deactivating, by the network side, one SCell of the frequency combination and activating thereafter, by the network side, the frequency corresponding to the MBMS service that is of interest to the UE; and when the network side determines that the frequency combination supported by the UE has not been activated completely, activating, by the network side, the frequency corresponding to the MBMS service that is of interest to the UE as the frequency corresponding to the SCell.
