Session establishment method, session management function entity base station and storage medium

摘要

The disclosure (disclosure) relates to LTE (Long Term Evolution) and 4G (4 ^th generation) 5G to support higher data rates than the subsequent communication system (5 ^th generation) or pre-5G communication system such. Embodiments of the present disclosure provide a method for setting up a session, the process comprising: receiving a message for creating a session management context; selecting a user plane functional entity (UPF) for redundant session processing in response to the message for creating the session management context; and setting a packet data unit (PDU) corresponding to the UPF. Session establishment methods may be further provided by the base station and related devices. The above technical solutions can realize the reliability of service transmission.
