Abstract: In general, techniques are described for handling errors in subscriber session management within mobile networks. A downstream mobile gateway comprising a forwarding unit and a service unit may implement the techniques. The forwarding unit receives a packet that includes a destination address for a subscriber and a tunnel endpoint identifier (TEID). The service unit determines whether the TEID is associated with one of a number of subscriber records that store session data for current sessions associated with subscriber devices to communicate with the mobile network. In response to determining that the TEID is not associated with one of the subscriber records, the service unit generates a message that includes the TEID and the destination address and indicates that the downstream mobile gateway has determined that the TEID is not associated with one of the subscriber records. The forwarding unit then sends the message to the upstream mobile gateway.

Abstract: A storage router and related method are presented for combining multiple host frames, such as Fiber Channel frames, together into a single datagram for tunneling transmission over an IP or similar network. The storage router operates by storing incoming host frames in a host frame buffer. When there is sufficient data in the buffer, multiple host frames are batched together, compressed, and converted into an IP datagram. The number of host frames to be batched together can be established through a variety of tests, including total bytes of data, number of frames, or through a time-out mechanism. The network layer then fragments the datagram into data link level frames, such as 1500 byte Ethernet frames. When the datagram arrives at the final destination, the segmented datagram is reconstructed, decompressed, and the multiple host frames are then extracted and passed on to the recipient host frame network.

Abstract: A method for controlling the transmission of data via data connections associated with different applications, by means of a transmission medium in a local network having at least two stations for data transmission. Different priorities and different parameters characterizing a quality of service are associated with the applications. The establishment, by a first station, of a new data connection associated with a first application is limited according to the available free channel capacity of the transmission medium and the use of the transmission medium by existing data connections having associated applications containing a priority corresponding to the first application.

Abstract: When wireless communications are made between a first wireless device and a second wireless device along a route, two wireless devices which exist between the first and second wireless devices each determine the lowest maximum transmission rate (11 Mbps) in the wireless intervals on the route from themselves to the second wireless device to be their own transmission rate txRate (11 Mbps) and two other wireless devices which exist between the first and second wireless devices each determine the lowest maximum transmission rate (54 Mbps) in the wireless intervals on the route from themselves to the second wireless device to be their own transmission rate txRate (54 Mbps).

Abstract: A method for interference-minimizing code assignment and system parameter selection for code division multiple access (CDMA) networks is disclosed. The method is performed at a base station or mobile station configured to operate in a CDMA radio network. The method includes receiving transmissions from user devices seeking to access the CDMA radio network. A spreading code is selected for a first user device seeking to access the network, using at least one cross-correlation parameter, to reduce multiple access interference between communications involving the first user device and other devices using the CDMA network. The method does not require knowledge of the active user codes or even the codebook from which these codes are assigned. Furthermore, it does not require knowledge of bit or chip epoch or the received powers of active users. However, the method can benefit from such knowledge in several ways, examples of which are disclosed.

The length information includes information representing a unit of the length information and information representing lengths of the packets according to the unit.

Abstract: Provided is a transmission system with increased degree of freedom in a lane configuration, which corrects disalignment of data sequences in respective channels due to differences in arrival time, thereby freely changing a number of lanes. The transmission system includes: a transmitter; a relay; and a receiver, the transmitter inputting data to be transmitted to the receiver, the relay transmitting the data transmitted by the transmitter to the receiver, the receiver receiving the data transmitted by the relay. The transmitter inserts into the data sequences channel information indicating a channel to which the data sequence is to be output. The relay corrects, based on the channel information, disalignment in an order of arrival of the data sequences received via a plurality of channels, the disalignment being generated by the differences in arrival time of the data sequences among the channels.

If a circuit is found to be out of service, the present invention will trigger a maintenance action through the edge component of the VoIP network to reset the circuit and restore it to a healthy condition.

Abstract: Several local IEEE1394 buses are bridged together over a second bus type to create a global bus wherein each local bus node is able to address nodes across the global bus without the local nodes being aware of the bridging operation. A bridging device operates by translating local bus node addresses to a global bus for communication over the second bus type. Alternatively, the local bus node identification process is controlled by the bridging device operating as the root node to cause the local nodes to be identified with a node address that is unique for the global network. The second bus type operates as a backbone for the global network and can be any type of communication bus or network with capability to transport the local bus traffic. The bridging devices that interface the local IEEE1394 buses to the backbone contain portals specific to each bus type that can communicate data between the dissimilar buses.
