  • Patent number: 8547875
    Abstract: The approach for managing the topology in a MANET includes, at the network layer of a wireless mobile node, operating a link state or other routing protocol to discover routes from the at least one wireless node to other wireless nodes within the MANET. The routing protocol includes the use of a global topology database storing global network topology information. The method also includes, at the network layer, providing the global network topology information from the global topology database of the routing protocol to the MAC sublayer. Also, at the data link layer, the MAC sublayer is controlled to perform neighbor connection management based upon the global network topology information from the global topology database. The approach may provide enhanced QoS, latency and resistance to link and node failures within MANETs.

  • Patent number: 6691274
    Abstract: Information packets are error encoded for transmission through a communication channel (34) in a communication system (10) using a variable payload outer code and a common physical layer inner code. The variable payload outer code is selected for each packet based upon an application or service associated with the packet. Thus, less coding can be used for packets associated with error tolerant applications and more coding can be used for packets associated with error sensitive applications. A common header outer code is also used for the packets. The variable payload outer code is preferably applied at the system adaptation level within an interworking function (22, 24) in the communication system (10). The common header outer code and the common physical layer inner code are preferably applied at the data link layer.

  • Patent number: 6144654
    Abstract: A method and apparatus for combining and separating groups of signals starts by a transmitter (500) receiving a number of CDMA-encoded signals from data sources (510). The CDMA-encoded signals are sorted (502) based on their intended destinations. Those CDMA-encoded signals which are intended for a common destination are multiplexed (504) together into a group. The group is further CDMA encoded (506) using a group code and the encoded group is transmitted (508) to an intermediate transceiver (600) or a destination transceiver (700). The intermediate or destination transceiver decodes (604, 704) the group using the appropriate group code and routes the resulting group of signals accordingly.

  • Patent number: 6078577
    Abstract: A packet data communication system (10) where multiple users (87) can access the same channel (22) to maximize an efficiency of the communication system (10). Each channel (22) is divided into time slots. Each time slot is allocated to a user based on the user's request (303) for time slots and the availability of time slots. If time slots are available, then the system (10) will inform the user (87) and allocate the time slot to the user (87, 305). If there are no available time slots, then the system (10) will inform the user (87) that no time slots are available and access to the system's channel is denied. The user (87) will continue to request access (303) to the system (10) as long as the user has data packets to send.

  • Patent number: 5930679
    Abstract: A satellite communication system provides users with global cellular coverage. To facilitate delivery of calls to users having subscriber units, a fixed channel is defined wherein subscriber units are notified of incoming calls. Subscriber units monitor this ring alert channel and examine subscriber unit IDs transmitted in a ring alert message contained therein. When a subscriber unit determines from the subscriber unit ID that a call is being directed to it, it calls into a network to receive a call. Subscriber units also monitor this fixed channel to receive a control channel directory identifying the location of a subscriber unit's broadcast (control) channels.
