The invention proposes solutions for monitoring and controlling the maximum number of the UEs registered in a Network Slice, the maximum number of the established PDU Sessions in a Network Slice and the maximum number of the Uplink and Downlink data rates per UE in a Network Slice. The invention also enforces access and service restriction in a Network Slice when the Network Slice parameters boundaries have been reached.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The disclosure is to analyze N network data on a UE which is in a roaming state in a wireless communication system. According to various embodiments of the disclosure, a method for operating an apparatus for a network data analytics function (NWDAF) belonging to a first network in a core network of a wireless communication system is provided. The method comprises: transmitting a first message requesting network data for a terminal to a core network device belonging to a second network; receiving a second message including the network data from the core network device; and transmitting a third message including an analytics result of the network data to a consumer network function (NF).

Provided in the present disclosure are a method and a device for providing a service to a user device by using a network slice in a communication system. A method according to one embodiment of the present disclosure can comprise the steps of: receiving, from a second network function device, management function configuration information about a first core network slice, including the quota of a first core network slice; reporting status information about the first core network slice to a third network function device on the basis of the management function configuration information; receiving, from the third network function device, parameters for controlling the status of the first core network slice; and controlling access of a terminal that is to use the first core network slice, on the basis of the status information about the first core network slice and the parameters for control.

A network device may select a first user plane function for establishing, with a user equipment, a protocol data unit session with a single flow and may receive an application function trigger associated with a first new flow for a first application of the user equipment. The network device may select a second user plane function for the first new flow and may create a first traffic filter for the first new flow. The network device may cause the first traffic filter to be provided to the user equipment so that first application traffic is routed, based on the first traffic filter, to the second user plane function and a first multi-access edge computing device associated with the second user plane function.

In one embodiment, an apparatus comprises a compressive sensing schedule generator configured to generate a plurality of compressive sensing schedules, wherein each of the plurality of compressive sensing schedules is for each of a plurality of frequency bands of a network, wherein the network comprises a plurality of access points and a plurality of clients, and a sensing matrix combiner configured to combine the plurality of compressive sensing schedules into a resulting schedule that comprises a spatial distribution and a scheduled time slot for each of the plurality of access points.

Methods and systems for citizens broadband radio service (CBRS) interference management using dual subscriber identification module (SIM) devices are described. The method includes assigning a physical cell identity (PCI) to each CBRS device (CBSD) granted unlicensed spectrum by a spectrum access system (SAS). Each spectrum granted CBSD may exchange PCIs with neighbor spectrum granted CBSDs to resolve PCIs and maintains a PCI table. A dual SIM device may be connected to a CBSD via a first SIM. Each spectrum granted CBSD having a connected dual SIM device reports a number of PCIs detected by the dual SIM device(s). A SAS designated dual SIM device may use a second SIM to measure power values of PCIs detected by the designated dual SIM device which are absent from a provided PCI table. The measured power values may be used by the SAS to make cluster interference decisions.
