  • Method for handling the simultaneous mobility of mobile hosts in infrastructure-based networks
    Patent number: 7319689
    Abstract: In infrastructure-based networks devices often move from one attachment point in the network or a sub-network thereof to another attachment point. Communications sessions may be established between Mobile Hosts attached to such nodes. Communications sessions between nodes established using Session Initiation Protocol (SIP), Mobile Internet Protocol with Location Registers (MIP-LR) or Mobile Internet Protocol version 6 (MIPv6) may fail if there is simultaneous mobility of two Mobile Hosts in an ongoing communication session. Stationary binding update proxies and stationary location proxies are introduced into such communications networks in order to provide a solution to the problem of simultaneous mobility of Mobile Hosts. Specific implementation for SIP, MIP-LR and MIPv6 are provided. IN SIP networks, the SIP server for the mobile hosts acts as the stationary binding update proxy and the stationary location proxy.

  • Multicarrier personal access communication system
    Patent number: 6654431
    Abstract: A highly modular PACS-based system that combines the advantages of Optical Frequency Division Multiplexing (OFDM) and Personal Access Communication System (PACS) with Time Division Multiple Access (TDMA) technology. The system is arranged to support high-speed (higher than the 32 kbps of PACS) wireless access services to fixed and mobile users. For example, nominal user data rates of 32-to-356 kbps are attainable, and ever the higher speed of 768 kbps is possible for short ranges.
