  • Patent number: 9008103
    Abstract: The present invention relates to a method, an apparatus, and a computer program product for providing access via a cellular access network to a packet-switched network, wherein a terminal-specific connection-oriented point-to-point link is set up between a terminal device and a cellular base station device, and the terminal-specific connection-oriented point-to-point link is switched at the cellular base station device on a link layer level to the packet-switched network, so that a point of attachment for said terminal device is located in the packet-switched network. Furthermore, a terminal-specific termination point for the packet-switched network is provided at the cellular base station device.

  • Patent number: 8780753
    Abstract: It is described a method of operating a base station and a base station which uses a communication channel depending on channel state related information and time information e.g. a prediction time. In this way, problems due to outdating of the channel state related information may be overcome and a feedback overhead may be reduced. According to other embodiments, other parameters like a used prediction method, a prediction horizon, etc. are used to provide a better scenario adaption. Other embodiments relate to combined long term prediction and short term prediction and respective timing settings. Other embodiments relate to a method of operating a user equipment and a user equipment which is adapted for communicating the required time information between the base station and the user equipment.

  • Patent number: 8774791
    Abstract: A method and apparatus for detecting and determining the location of a coverage hole in a communications network such as a cellular communication system wherein the location is determined from operational parameters and/or by network elements themselves. Additionally is a method to reduce a hole by adjusting antennae parameters preferably remotely and automatically and this can be done in conjunction with hole location to optimise the system.
