  • Patent number: 8644403
    Abstract: An Orthogonal Frequency Division Multiplexing (OFDM) symbol for transmission from a non-reference transceiver to a user equipment (UE) in a mobile communication system is generated by ascertaining a general timing for transmission of OFDM symbols, in which the general timing is associated with a reference transceiver. A UE timing relative to the general timing is ascertained. An initial resource element (RE) value is adjusted by a pre-compensating amount to obtain a pre-compensated RE value, in which the pre-compensating amount is based on the UE timing relative to the general timing. The pre-compensated resource element value is supplied as one of a plurality of values to be transmitted. An IFFT is performed on the plurality of values to be transmitted to obtain pre-compensated initial signal information. A cyclic prefix is appended to the pre-compensated initial signal information to form an OFDM symbol for transmission from the non-reference transceiver to the UE.

  • Patent number: 8644476
    Abstract: Method and communication system for providing a value added service, such as an intelligent network (IN) service, which is available in a first network (5), to a subscriber (3) in a second network (7). The first network (5) comprises a first network node (11) for executing the value added service. The method comprises detecting in a terminating call to the subscriber (3) that the subscriber (3) desires to use the value added service, forwarding control of the call towards the first network node (11) associated with a forwarding number in the first network (5), executing the value added service by the first network node (11), and, when necessary, further directing the call towards the subscriber (3) associated with the terminating call. The present method can also be applied to originating calls from a subscriber. In this case, the call is further directed towards a destination associated with the call.

  • Patent number: 8644252
    Abstract: The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.

  • Patent number: 8644874
    Abstract: Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore ‘UP’ transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

  • Patent number: 8646085
    Abstract: The invention relates to an apparatus for analyzing and reconfiguring a technical system (2) with respect to security, as well as a corresponding decision support system and computer program product. A graph constructor (20) provides, based on technical information about the system (2) received via an input interface (10), a representation of potential attacks in a directed graph of attack nodes. A system/countermeasure analysis unit (30) ranks different sets of countermeasures to enable a selected set of countermeasures to be taken to improve security. The analysis unit (30) performs the following procedure for each set of countermeasures: i) logically apply the set of countermeasures to attacks in the directed graph, and ii) determine a rank of the applied set of countermeasures based on the effectiveness of the countermeasures with respect to the reduction of the risk of attacks.

  • Patent number: 8644256
    Abstract: A method of forwarding IP packets, sent to an old care-of-address of a mobile node, to the mobile node following a handover of the mobile node from a first old access router to a second new access router. The method comprises, prior to completion of said handover, providing said first router or another proxy node with information necessary to determine the new IP care-of address to be used by the mobile node when the mobile node is transferred to the second access router. At said first router or said proxy node, the new care-of-address for the mobile node is determined using said information and ownership of the new care-of-address by the mobile node confirmed, and subsequently packets received at said first access network and destined for said old care-of-address are forwarded to the predicted care-of-address address.
