  • Publication number: 20200092709
    Abstract: The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node.

  • Patent number: 9813901
    Abstract: Disclosed is a technique for performing flexible service-level access control in real-time while suppressing occurrence of signaling. According to the technique, a network entity (AAA server 10) configured to perform access control sets correspondences between addresses of a communication terminal (UE) 40 and respective service contents of services that the communication terminal 40 receives, and notifies the communication terminal of the correspondences. Thus, the communication terminal is able to know the service contents corresponding to the addresses that the communication terminal uses. In a case where a service content of a service that the communication terminal receives is changed, the address used by the communication terminal is changed to an address corresponding to the changed service content. As a result, from the changed address, the communication terminal is able to know that the service content has been changed and to know the changed service content.

  • Patent number: 9680683
    Abstract: A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part. A GI extracting part extracts, from the signal subjected to the radio reception process by the received RF part, GI having a length determined by an extracted GI length deciding part. The extracted GI is adjusted by a data position adjusting part such that its rear end coincides with the read end of the extracted data portion. A combining part combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part, which equalizes the signal distortions of the combined signal on the frequency axis.
