Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for terminal devices influenced network slice selection. According to embodiments of the present disclosure, a new terminal device influenced network slice selection is proposed. The NRF updates the application profile for the terminal device based on the change of the applications on the terminal device. The NRF may notify the PCF about the application profile and the PCF generates the route policy for the application on the terminal device. In this way, problems regarding the affected terminal devices of application influenced network slice selection are solved.

Abstract: Aspects described herein relate to various methods, systems and apparatuses that can be used to configure and manage a network slice based on billing rate information. By selecting a network slice based on billing rate information, the system may further be able to respond to billing rate changes by reselecting network slices. For example, changes in the usage of the network slice or the usage of the overall network infrastructure may cause a change to a billing rate associated with the network slice. These aspects, and others described herein, may result in improved network performance by, for example, offloading extra usage from an overloaded network slice to a network slice that is currently less used.

Abstract: Embodiments of the present disclosure relate to for controlling D2D routing. A first device generates proximity information for a D2D connection group. The first device obtains information concerning a second device in the group. The first device generates a D2D route policy for at least one application on the second device, based on the generated proximity information, the obtained information concerning the second device and route selection criteria for the group, the policy at least indicating the route selection criteria and D2D paths satisfying the route selection criteria. The first device sends the D2D route policy for routing traffic of the at least one application in the group by the second device.

Abstract: Systems, apparatuses, and methods are described for configuring quality of service (QoS). For example, a computing device, which may be configured to operate as one or more network functions of a fifth generation wireless system (5G), may be associated with a first network. The computing device may receive, from an application or service server, and via a second network, QoS information. The QoS information may associate an application or service with one or more QoS flow identifiers (QFIs) or other indicator of a level of QoS. A PDU session may be established for a user device and the application or service. Based on the QoS information, the computing device may send a request that causes the PDU session to be modified. Upon modification, the PDU session may transport, based on data including the QFI or other indicator of a level of QoS, the data via the first network.

Abstract: Embodiments of the present disclosure relate to a method and corresponding device for controlling a remote UE to access to a network via a relay UE. The method includes: the remote UE receives, from a proximity service function, an access level configuration message, which contains access level allocated to the remote UE; receiving access restriction configuration information from the relay UE via a PC5 interface; when an application on the remote UE initiates a request for accessing the network, rejecting the request for accessing the network if the access level of the remote UE is matched with the access restriction configuration information. A device capable of implementing the above method is also disclosed.
