The patent EP2291033 was granted to Koninklijke KPN on Sep 28, 2022. The application was filed on Feb 19, 2009 under application number EP10174609A. The patent is currently recorded with a legal status of "Patent Maintained As Amended".
A telecommunications network and method for regulating network resource usage, particularly suited for Machine-to-Machine (M2M) applications. The network allows dynamic time-based access control, enabling operators to restrict or permit access during specific time intervals. This approach optimizes resource utilization by preventing unnecessary network attachment and PDP context establishment during peak periods. The system also enables transmission of access control information to terminals, facilitating controlled operation and authentication procedures.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
