A client device receives a broadcast content signal containing an interactive identifier over a managed network at a client device. The interactive identifier may be a trigger that is included in a header or embedded within the digital video data. The trigger may have a temporal component, wherein the trigger can expire after a certain period of time. In response to identification of the trigger, the client device sends a user request for interactive content over an unmanaged network. For example, the managed network may be a one-way satellite television network, IP-television network or cable television network and the unmanaged network may be the Internet. The client device switches between receiving data from the managed network to receiving data from the unmanaged network.

This invention describes a new methodology for a cell reselection by a mobile station (MS) for improving network interconnection and interoperability in a limited mobile access environment. The invention is applicable to any kind of networks and their interconnections. The invention describes how the MS can better recover from failed intersystem cell reselection attempts so that there are fewer subsequent failed attempts using two major improvements. First, the MS takes into consideration during cell reselection evaluation and candidate-cell selection, whether the MS had previously been unsuccessful in reselecting the considered cell. This means treating neighbor cells to which the MS had failed reselection before with a lower priority in subsequent cell reselection evaluations. Second, the MS is allowed to stop monitoring and thus, to stop evaluating cells if it was earlier found that the access to those cells is forbidden.
