Abstract

A method for a device interacting with network functions to adjust Quality of Service (QoS) within a group comprises: receiving a group QoS adjustment request for terminals subject to group QoS adjustment from a service server; determining whether the cell locations of the terminals subject to adjustment included in the group QoS adjustment request are identical; if the cell locations of the terminals subject to adjustment are identical, adjusting the QoS values of the terminals subject to adjustment within a QoS adjustment range obtained by summing the basic QoS values of the terminals subject to adjustment; and transmitting the adjusted QoS values of the terminals subject to adjustment to a Policy Control Function (PCF) to request the application of a QoS policy to the sessions of the terminals subject to adjustment. The group QoS adjustment request includes a request for an upward adjustment of QoS for at least one terminal among the terminals subject to adjustment.

Description

Method for Arranging Service Quality Within a Subscribing Group in 5G Networks, and Network System for the Same The present invention relates to a Quality of Service (QoS) provision technology. 5G networks provide Radio Access Networks (RAN) and Core networks separated into slices through sliced networks. By utilizing sliced networks, 5G networks can provide dedicated networks suitable for services. The dedicated network can set a Reference Service QoS and accommodate services using the set QoS in separate slices. 5G networks can provide ultra-high speed, ultra-low latency, and high-quality services, allowing for differentiated service quality depending on the type of service, such as high-quality media services and IoT services. Through these characteristics of 5G networks, various new convergence businesses can be created, and differentiated service provision is necessary when resource consumption varies by industry or service. Meanwhile, network neutrality, which requires that data traffic be treated equally regardless of target, content, or type of service, may be required of telecommunications operators. This aims to ensure that all subscribers can use data under equal conditions; for example, the data required for Netflix to transmit videos and the data required for individual users to send messages must be treated equally. However, 5G networks designed to provide differentiated service quality pose a problem that conflicts with network neutrality, which requires that service quality not be discriminated against among subscribers.

FIG. 3 is a flowchart of a method for adjusting service quality within a group according to one embodiment.
