Title: Systems and methods for home carrier determination using a centralized server
Inventor: NASIELSKI JOHN WALLACE
IPC: H04W12/06
Filed: 2004-09-13
Abstract: Systems and methods for determining the home network carrier associated with a mobile station and authorizing the provision of services to the mobile station using centralized storage of mobile station and home network information. In one embodiment, when a roaming mobile station attempts to access services, identifying information for the mobile station is used by a local server to query a centralized DNS server that stores a mapping of mobile station identifying information to corresponding home networks. The centralized DNS  server returns an identification of the home network of the roaming mobile user, and the home network then determines whether to grant or deny the mobile station access to the local network. The mobile station identifying information may comprise an MSID such as an MIN, IRM or IMSI, which may serve as part of the address for the query to the centralized DNS server.
Patent CA-2538750-A1 (CA)
Title: Method for configuring air-core photonic-bandgap fibers free of surface modes
Inventor: SHIN JONGHWA
IPC: A61K45/06
Filed: 2004-09-10
Abstract: Coupling of core modes to surface modes in an air core photonic-bandgap fiber (PBF) can cause large propagation losses. Computer simulations analyze the relationship between the geometry and the presence of surface modes in PBFs having a triangular hole pattern and identify ranges of core characteristic dimensions (e.g., radii) for which the fiber supports no surface modes (i.e., only core modes are present) over the entire wavelength range of the bandgap.  In particular, for a hole spacing and a hole radius = 0.47 , the core supports a single mode and supports no surface modes for core radii between about 0.7 and about 1.05 , which suggests that such fibers should exhibit a very low propagation loss. The existence of surface modes can be predicted simply and expediently by studying either the bulk modes alone or the geometry of the fiber without requiring a full analysis of the defect modes.
