1. A method for transmitting multicarrier-supported capability of User Equipment (UE), comprising:

  • sending out, by UE, a message carrying multicarrier-supported capability of the UE, when the UE supports multicarrier;

    parsing, by an Radio Network Controller (RNC), a message carrying multicarrier-supported capability of UE received from the UE; and

    obtaining the multicarrier-supported capability of the UE;

    the method further comprises;

    after the RNC obtains the multicarrier-supported capability of the UE,deciding, by the RNC, that a service is received by a multicarrier cell, wherein the deciding comprises;

    carrying, by the RNC, auxiliary carrier cell information in a radio link setup request message or in a radio link reconfiguration request message which is sent to a NodeB, and carrying the auxiliary carrier cell information in a radio bearer setup message or in a radio bearer reconfiguration message which is sent to the UE;

    wherein the multicarrier-supported capability indicates the multicarrier-supported High Speed Downlink Packet Access (HSDPA) capability in a 3G system;

    wherein the step of sending out, by the UE, the message carrying the multicarrier-supported capability of the UE comprises;

    expanding a level of a High Speed-Downlink Shared Channel (HS-DSCH) physical layer category to add a level of the multicarrier supported capability of the UE; and

    sending out an RRC connection setup complete message or a UE capability information message carrying the expanded HS-DSCH physical layer category when the UE supports multicarrier.
