Patent number: 11800322Abstract: Improved techniques of reducing latency in UL positioning include generating a priority indication by the LMF for all UE requiring UL positioning. For example, an LMF can generate a priority list identifying UEs within a network that may be considered by a serving network node (gNB) for positioning prioritization. In some implementations, the serving gNB indicates that prioritizing all of the identified UEs would require more network resources than are available. In such a case, the LMF obtains latency measurement values for TRPs in the network. Based on the latency measurement values obtained, the LMF performs a configuration operation on at least one of the TRPs to reduce the UL positioning latency to an acceptable value.Type: GrantFiled: April 15, 2021Date of Patent: October 24, 2023Assignee: Nokia Solutions and Networks OyInventors: Oana-Elena Barbu, Ryan Keating

Patent number: 11777846Abstract: SR-enabled network nodes capable of replicating and recombining data packets in a manner that enables reliable, low-latency communications. In an example embodiment, a replicator node transmits to a combinator node multiple copies of a payload over different respective network paths, with the SR headers of the corresponding packets each having a replication segment identifier or a respective SID stack that includes the replication segment identifier. The combinator node delivers/forwards to the corresponding application/destination only the first-to-arrive payload copy and discards any subsequent payload copies based on the replication segment identifier. Some embodiments may beneficially reduce latency and packet loss concurrently and consistently. For example, packet loss may be reduced due to the transmission of multiple copies of the same payload over multiple network paths. Effective latency may be reduced due to the selection of the first-to-arrive payload copy for delivery/forwarding.Type: GrantFiled: May 6, 2020Date of Patent: October 3, 2023Assignee: Nokia Solutions and Networks OyInventors: Thierry Van de Velde, Satish Kanugovi

Patent number: 11770465Abstract: A first router transmits a first message including information identifying a first set of transport layer protocols supported by the first router. The first router receives a second message including information identifying a second set of transport layer protocols supported by a second router. A common transport layer protocol is selected from a subset of transport layer protocols that are common to the first and second sets of transport layer protocols. The first router then establishes a border gateway protocol (BGP) session with the second router over the common transport layer protocol. The first message is unicast to the second router or broadcast/multicast over a plurality of links to a plurality of routers that includes the second router. In some cases, the common transport layer protocol is selected by the router having a higher priority, based on preferences, or a combination thereof.Type: GrantFiled: October 20, 2020Date of Patent: September 26, 2023Assignee: Nokia Solutions and Networks OyInventor: Pranjal Kumar Dutta

Patent number: 11770187Abstract: A performance monitor configured to unify at least two different signal-quality estimates into a single performance metric such that a systematic error associated with the performance metric can be approximately constant or smaller than a specified fixed limit over a significantly wider range of data-link conditions than that of a conventional performance metric of similar utility. In an example embodiment, the performance metric can be based on a weighted sum of two different SNR estimates, obtained from an error count of the receiver's FEC decoder and from a constellation scatter plot generated using the receiver's symbol decoder, respectively. Different weights for the weighted sum may be selected for different data-link conditions, e.g., using SNR thresholding, analytical formulas, or pre-computed look-up tables. The performance metric may be supplied to a control entity and considered thereby as a factor in a possible decision to trigger protective switching and/or a transponder-mode change.Type: GrantFiled: October 17, 2022Date of Patent: September 26, 2023Assignee: Nokia Solutions and Networks OyInventors: Camille Delezoide, Petros Ramantanis
