Patent No. EP2291033 (titled "Telecommunications Network And Method For Time-Based Network Access") was filed by Koninklijke KPN on Feb 19, 2009. The application was issued on Sep 28, 2022.
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.
