Abstract: A contextual SS7 firewall filter is inserted between a network operator and its roaming partners intra network and inter network SS7 traffic. SS7 firewall filter validates GSM MAP and GSM CAP messages based on specific criteria as provisioned for those message types and either allows them or blocks them from reaching their intended destination based on the validation results. The validation step involves verification of MSU correctness, verification of correctness of SS7 MTP fields for each MSU, and verification of correctness of SS7 SCCP fields for each MSU. SS7 firewall filter blocks GSM messages that fail at least one of the verification steps.

Abstract: This spectrum protection system enables spectrum sharing that protects Earth Exploration-Satellite Services (EESS) observations, which allows for uninterrupted weather forecasting, from terrestrial operations that operate near or within EESS frequency bands without cumbersome restrictions on telecommunications (telecom) providers. The system calculates the satellite observation times using a device's location recognizing that these satellites are only observing a particular location on Earth for a very small amount of time because of their orbital dynamics and scanning characteristics. Using this calculated list of observation times and comparing it to the current time input, the system then enacts a mechanism for action when EESS observations are occurring. Two simple embodiments for the mechanism for action include momentarily changing frequencies or reducing transmission power levels to prevent erroneous EESS measurements.

By lowering the volume of UE that are located in a particular edge-region of a sector of a cell site, the remaining portion of the UE that are located in a particular edge-region of a sector of a cell site experience improved throughput.

The first device housing is pivotable about the hinge relative to the second device housing. The hinge separates a first chamber defined by the first device housing and a second chamber defined by the second device housing. A flexible substrate passes through the first chamber and the second chamber. The flexible substrate spans the hinge, either by passing through or around a hinge housing. The flexible substrate deforms to a curvilinear deformed state within one or both of the first chamber or the second chamber when the first device housing and the second device housing pivot about the hinge from a closed position to an axially displaced open position.
