Open the CIPO recordAbstract From the Canadian patent
A method and a system for collecting session-specific event data in a telecommunications network where sessions are connected through a number of network entities which generate event data and have mutual signaling connections. The objective of the invention is to provide a solution whereby event detail records relating to one session but generated by a number of different network entities are sent in a centralized manner in real-time to a given collecting network entity. Thus, the event data combination is optimized and the unnecessary transmission of event detail records from one collecting network entity to another is avoided.

Why it's free to use
- Filed May 28, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 28, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 28, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
