  • Patent number: 6584314
    Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

  • Patent number: 6385446
    Abstract: In telecommunications networks the problem with call forwarding restriction according to prior art is that access through call forwarding to numbers with ensuring an answer rather than possible further forwarding is not possible. The invention is based on the idea that call forwarding is allowed despite call forwarding restriction when the number to be used in forwarding the call meets special conditions set beforehand. The number is thus compared with the preset conditions and depending on the result of this comparison the call is either forwarded or not.

  • Patent number: 6167256
    Abstract: A mobile services switching center for forwarding a subscriber directory number terminating call to a call forwarding number which is retrieved from a separate subscriber database. The mobile services switching center contains a call forwarding database which stores directory numbers of forwarding parties from each of which a set-up of a forwarded call is in progress. The call control of the mobile services switching center is arranged to check, prior to initiating call forwarding, whether a directory number of the forwarding party is included in the call forwarding database.

  • Patent number: 6052369
    Abstract: For packet data transmission between fixed network elements, such as a mobile exchange, a base station controller and base stations, in a mobile communication system, a node-to-node packet data transmission in a digital mobile communication network is carried out by using network elements as packet nodes and by utilizing existing signalling protocols between them for transmitting data packets. Only a processing of incoming and outgoing data packets is introduced into the network elements. The normal signalling messages of a mobile communication network used for packet data transmission are only provided with a new identifier indicating that the message contains packet data, so that the packet data messages can be forwarded to the packet data processing, instead of normal signalling message handling.
