    摘要: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate after a 4th generation (4G) communication system such as long-term evolution (LTE). An operating method of a device for a user plane function (UPF) in a core network of a wireless communication system may include receiving rule information for processing a packet from a device for a session management function (SMF), processing a packet including user traffic received from a first device based on the rule, and transmitting the processed packet to a second device. Herein, first device or the second device may be a different device which performs a function related to a user plane.

    摘要: A method for setting a value of an inactivity timer for transitioning between states of a data session in a network comprising a first entity and a second entity providing network analytics is provided. The method includes obtaining, by the second entity, input data comprising communication description information for at least one user equipment (UE), and providing, by the second entity to the first entity, output analytics generated based on the input data, the output analytics comprising UE communications analytics for each data session where the output analytics are used to determining whether to update a value of an inactivity timer for a data session.

    摘要: The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a SMF entity in a wireless communication system. The method comprises identifying whether to deactivate an UP connection of a first PDU session of one or more established PDU sessions, identifying whether the first PDU session supports an UP optimization based on the identification, and transmitting, to an AMF entity, a first message for deactivating the UP connection.
