A transmission terminal support dual-band multi-carrier capability of the method and system

The present invention discloses a method for multi-carrier transmission terminal support dual-band capability, when the UE supports dual-band multi-carrier bands supported by the UE and the combination information of each frequency band capability to support the number of downlink carriers configured to carry with a radio network controller (RNC) transmits interactive message to the RNC. Accordingly, the present invention also discloses a dual-band transmission terminal system multi-carrier capability. Since the RNC interactive message from the UE parses able to obtain the number of the downlink carrier frequency band supported by the UE compositions and combinations of the two frequency bands are each configured to support, when resource allocation for reference, therefore, the present invention conducive to the rational allocation of network resources, improve network resource utilization.
