Abstract:
Aspects of the subject disclosure may include, for example, accessing a service by a first network operating within a first wireless spectrum, wherein the service includes control and data forwarding operations of the first network are separate and configured to facilitate forwarding of user data via the data forwarding operations. A second network is identified operating within a second wireless spectrum. A request that the accessing of the network service be transferred to the second network is made without interrupting the forwarding of the user data. A response to the request is detected via the control operations, also without interrupting the forwarding of the user data. Responsive to an indication that the second network has been configured to accommodate a redirection of the forwarding of the user data from the first network to the second, the redirection is facilitated. Other embodiments are disclosed.
