Abstract: A method, system, and medium are provided for regulating the allocation of radio-frequency (RF) channels in a carrier-aggregation network. A base station that is part of the carrier-aggregation network receives a registration request from a mobile station subscribing to services offered by a first wireless-telecommunications network within the carrier-aggregation network. The base station communicates the registration request to the first network and receives a set of policy parameters from the first network. The base station receives a service request from the mobile station. Based on the policy parameters and the service request and without communicating with the first network, the base station determines a set of RF channels available to the mobile station. The base station sends a resource assignment to the mobile station specifying the set of available RF channels.
