Abstract: The disclosure relates to a method and a device for controlling a data rate in a network slice of a wireless communication system. A method for controlling a bit rate of a network slice by a session management function (SMF) device of a wireless communication system is provided. The method includes receiving a slice control policy information from a policy and charging function (PCF) device, transmitting, to a user plane function (UPF) device, a parameter for controlling each slice based on the received slice control information, and receiving, from the UPF device, a response signal for whether the transmitted parameter is acceptable.

Abstract: Disclosed is a 5G or a pre-5G communication system provided to support a higher data transmission rate than that of post-4G communication systems such as LTE. A method of operating a network node in a wireless communication system includes: receiving, from at least one user plane function (UPF) instance, a registration request message including UPF profile information of the at least one UPF instance; storing the UPF profile information including UPF service support information for at least one UPF service supported by the at least one UPF instance, receiving, from a session management function (SMF) node, a UPF discovery request message including UPF service information; discovering one or more UPF instance based on the UPF profile information and the UPF service information; and transmitting, to the SMF node, UPF instance information for the one or more UPF instance.

Abstract: The disclosure relates to a communication technique of converging a 5th generation (5G) communication system for supporting higher data rates after a 4th generation (4G) system with Internet of things (IoT), and a system therefor. The disclosure provides a method performed by a first network entity managing a packet data network (PDN) session in a wireless communication system supporting interworking between a first and second networks. The method comprises receiving subscription update information of a user equipment (UE) for which a PDN connection associated with a network slice is established in the second network, the network slice being subscribed in the first network, determining whether to release the PDN connection if the subscription update information includes information notifying that network slice related information of the UE is changed, and performing a release of the PDN connection associated with the network slice if the release of the PDN connection is determined.

Abstract: 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.
