Abstract: The present invention relates to systems and methods for re-establishing an interrupted connection between nodes in a wireless network. More particularly, the present invention relates to systems and methods for re-establishing the connection in such a way to avoid excessive signaling load.

Abstract: A radio access network provides information to a mobile radio terminal indicating a list of one or more geographic coverage areas from which the mobile radio terminal may or may not obtain service. In the preferred example embodiment, a “forbidden” list includes one or more geographic coverage areas from which the mobile radio terminal may not obtain service. The mobile checks the received information when considering whether to request service from a new geographic coverage area, and determines whether to select the geographic coverage area depending on that received information. Moreover, the mobile terminal consults that list to determine whether to perform a location area update procedure. In other words, if the list indicates that a new geographic coverage area should not be selected, the mobile terminal does not perform a location area update request in that new coverage area.

Abstract: A flexible consistency checking mechanism allows network operators to create their own consistency checking rules. Several consistency check formulas are provided. Each formula defines one or more general operations on one or more managed network objects. By applying a general consistency check formulas to one or more specific managed network objects, one or more consistency check rules is generated. For example, the user can generate the consistency check rules simply by inputting certain data values for formula variables by way of a user interface. Once those rules have been generated, they can be used to check the consistency of one or more aspects of a communications network configuration. Each formula also may include a checkpoint that defines a time period or event when a corresponding consistency check rule established using that formula should be executed.

Abstract: A connection is established between a mobile radio terminal and a radio access network serving plural geographic coverage areas. The radio access network transmits information associated with one of the geographic coverage areas indicating whether the one geographic coverage area requires a geographic coverage area update procedure. During the connection, when the mobile radio terminal considers selecting the one geographic coverage area, it determines whether to perform a geographic coverage area update procedure depending on the transmitted information associated with the one geographic coverage area.
