Patent ID: 8340704

Claim:
A resource allocation method for a multi-mode terminal, the method comprising: obtaining, by a control network element of a first network technology type, information about a radio resource of a second network technology type, wherein the radio resource of the second network technology type is used by the multi-mode terminal and the information about the radio resource of the second network technology type indicates a carrier frequency; and according to the carrier frequency indicated by the information of the radio resource of the second network technology type and according to a maximum spectral width between a service of the first network technology type and a service of the second network technology type, determining, by the control network element of the first network technology type, that a carrier frequency allocated to the multi-mode terminal serves as a radio resource of the first network technology type, wherein a difference value between a carrier frequency of the radio resource of the first network technology type and the carrier frequency indicated by the information about the radio resource of the second network technology type is within a range of the maximum spectral width.
