System and method for providing access in a network environment

摘要

A method is provided in one example embodiment and includes evaluating geolocation information associated with a mobile node and using the geolocation information to identify a femtocell capable of providing network access to the mobile node. A primary scrambling code is provided to the mobile node for operation in an idle mode. The method also includes communicating a secondary scrambling code to initiate access to the femtocell by the mobile node when operating in an active mode. In more particular embodiments, the secondary scrambling code is included in a broadcast message that includes a femtocell identifier associated with the femtocell. The femtocell is identified from a plurality of femtocells based on geolocation information associated with the femtocell. The primary scrambling code is part of a range of primary scrambling codes allocated to a plurality of femtocells within a macro network coverage area.

1. A method, comprising:
evaluating geolocation information associated with a mobile node; using the geolocation information to identify a femtocell capable of providing network access to the mobile node, wherein a primary scrambling code is provided to the mobile node for operation in an idle mode; using the geolocation information to dynamically select an optimum secondary scrambling code; and communicating the secondary scrambling code to initiate access to the femtocell by the mobile node when operating in an active mode, wherein the primary scrambling code is a shared code and the secondary scrambling code is unique to the femtocell; wherein additional network information is used to determine whether a neighbor cell database should be accessed in identifying the femtocell to provide access to the mobile node; wherein the secondary scrambling code is included in a broadcast message that includes a femtocell identifier associated with the femtocell; and wherein the secondary scrambling code is used to hand-in the mobile node from a macro network to the femtocell.
