DECENTRALIZED SESSION MANAGEMENT

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.
