Patent number: 11695818Abstract: An interface may be provided between i) a selective forwarding unit (SFU) configured to, in real-time, receive a data stream from a sender via a first network link of a communication network and selectively forward the data stream to one or more receivers via respective second network links, and ii) one or more core network functions (PCF, PCRF, NSMF, CSMF) for establishing service guarantees for data flows in the communication network. In a specific example, the interface may be established as a network function (SMGF) which translates streaming requirements for one-to-many flows coming from WebRTC SFUs into appropriate QoS/network slice configurations, such that the quality of RTC flows may be increased. Accordingly, negative side-effects of conservative congestion control algorithms in WebRTC clients and static/overprovisioned QoS at network operators may be overcome.Type: GrantFiled: March 13, 2020Date of Patent: July 4, 2023Assignees: KONINKLIJKE KPN N.V., NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNOInventors: Jan Willem Martin Kleinrouweler, Pieter Nooren, Lucia D'Acunto

Patent number: 11665260Abstract: A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.Type: GrantFiled: April 13, 2018Date of Patent: May 30, 2023Assignees: Koninklijke KPN N.V., Nederlandse Organisatie voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Konstantinos Trichias, Lucia D'Acunto, Bastiaan Wissingh, Ray Van Brandenburg, Thomas Attema
