Latest Patents
One of Hartikainen's latest patents is related to location management in a mobile telecommunication system. The invention aims to separate the location area used in the Radio Access Network (RAN) from the reporting area used when communicating the mobile's location to the core network. This separation allows for the size of the location area to be optimized based on the services utilized by the subscriber, thereby enhancing the efficiency of radio resources. The reporting area, which may consist of multiple location areas, is determined based on the accuracy of location information required by the core network. The RAN notifies the core network when a subscriber exits their current location area, and the two networks negotiate the size of the reporting area before service activation.
Another significant patent by Hartikainen addresses the management of packet-switched connections in mobile communications networks. This invention tackles the issue of unnecessary resource reservation in connection-oriented switching of packet data. By releasing the logical connection between the serving node and the radio network subsystem while maintaining the connection with the mobile station, the method optimizes resource usage. The released logical connection can
