  • Industrial Automation with 5G and Beyond
    Publication number: 20200259896
    Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

  • Method and arrangement for route cost determination and selection with link cost interaction
    Patent number: 9674073
    Abstract: This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case.

  • Access node selection in a network
    Patent number: 8938525
    Abstract: The invention is directed towards determining an access node (14, 16) for a terminal (18) in a network (10) having one or more access nodes capable of providing access to the terminal based on one or more access technologies. Access node is selected through determining whether at least one network parameter provided by a network node (12, 14, 16) is required as input for the access node selection for the terminal. If it is determined that the at least one network parameter is required as input, the network parameter is obtained and an access node possibly together with access type for the terminal is selected at least based on said network parameter.

  • Data transmission over a communications link with variable transmission rates
    Patent number: 6307867
    Abstract: An optimal data block size is determined for use in transmitting data at variable rates over a communications link in predetermined time intervals, where each predetermined time interval has the same time duration. Rather than varying data block size according to changes in transmission rates, which adds unnecessary complexity, the data blocks all have the same fixed size, i.e., the same number of data bits in each block. That fixed data block size is determined so that for all of the available data transmission rates, each predetermined time interval is fully occupied with useful information. The fixed data block size is determined based on a maximum frequency at which the transmission rate may change on the communications link and a lowest available transmission rate.

  • Packet data communications scheduling in a spread spectrum communications system
    Patent number: 6236646
    Abstract: In a spread spectrum communications system supporting bursty uplink and downlink data packet transmission telecommunications services, significant concerns exist as to the generation of unacceptable levels of interference resulting from plural and simultaneous data packet transmissions. To address this concern, the system selectively organizes an access schedule for mobile station uplink data packet transmissions and a delivery schedule for downlink data packet transmissions. For the uplink, the schedule is transmitted to plural mobile stations in a current frame, and identifies which one or ones of plural mobile stations are authorized to make an uplink data packet transmission in a next frame. Only those mobile stations scheduled with authorization to make an access in the next frame then transmit their data packets (or a portions thereof) to the base station during that next frame. On the downlink, a notification of intended delivery is communicated to destination mobile stations in a current frame.
