Abstract
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.
