Abstract: This disclosure relates to managing sessions in a mobile communication network, for instance, a 5G network. The disclosure proposes a first entity for a decentralized session management, which may be performed together by a plurality of first entities. The first entity receives a first transaction indicating information of a first session-management-related message, and sends it to other first entities. Further, it receives second transactions from the other first entities, wherein each second transaction indicates information of a second session-management-related message. Then, the first entity composes a first transaction set including the first transaction and/or the second transactions, and performs a distributed consensus protocol with the other first entities, to obtain a consensus result indicating whether the first entity or one of the other first entities is entitled to propose the first transaction set or second transaction set.

Abstract: The disclosure relates to a method for operating a network function, NF1, of a first network slice, NSI-2, wherein the method comprises establishing an end-to-end path from NF1 of NSI-2 to a network function, NF2, of a second network slice, NSI-1. Moreover, the disclosure relates to a corresponding communication network.

Abstract: A network entity controls an end-to-end service. The end to end service is provided across an operator network domain and a service provider domain. The network entity is configured to determine an adjustment for a network function in the domain of the network entity based on performance indicator data of the other domain and requirements of the end-to-end service. The performance indicator data of being real-time performance indicator data of the end-to-end service. The network entity is configured to send an instruction to adjust the network function in accordance with the determined adjustment.

Abstract: Derivative polypeptide derived from a grass carp interferon and an application of the derivative polypeptide. An amino acid sequence of the derivative polypeptide is as shown in SEQ ID NO:1; the interferon-derived polypeptide has a high-efficiency antibacterial effect and can take effect against drug-resistant Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus agalactiae, Vibrio fluvialis or Aeromonas hydrophila. The interferon-derived polypeptide is less toxic to eukaryotes and can effectively reduce the mortality of mice in a mouse disease model caused by pathological bacteria. The interferon-derived polypeptide which is small in molecular weight is easily synthesized and has a good application value.
