The application provides an associated channel resource allocation method, which is realized through a wireless network controller. The associated channel resource allocation method comprises the steps of: receiving a request transmitted by a terminal for constructing packet service, and allocating high-speed downlink packet access resource; acquiring the terminal identification code from the request; and determining whether the terminal exists in a pre-stored list prohibiting using channel frame division multiplexing according to the terminal identification code, allocating the associated channel frame division multiplexing resource to the terminal if the terminal does not exist in the list, otherwise, allocating other resource to the terminal. The application also provides an associated channel resource allocation device for realizing the method. The associated channel resource allocation method and device provided by the application can pre-determine the terminal according to the list so as to allocate resources according to the actual condition, thereby improving cell capacity, obviating call drop, balancing the cell capacity and the call drop, improving utilization rate of network resources, and ensuring normal conduction of the terminal data service.
