An AMF apparatus () receives a NAS message for requesting a core network to establish or activate a PDU session associated with an allowed network slice identifier, from a UE (), via a first cell () not supporting the allowed network slice identifier and via a first AN node () that provides the first cell (). In response to receiving the NAS message, the AMF apparatus () sends to the first AN node () a control message that causes the first AN node () to move the UE () to a second cell () that supports the allowed network slice identifier. This can contribute, for example, to enabling an establishment or activation of a PDU session associated with a network slice that is supported only in sparsely (or patchily) placed local cells.

AMF apparatus, access network node, and methods therefor

The present disclosure proposes solutions for monitoring, controlling and enforcement the number of the UEs per Network Slice quota in roaming. It proposes new Network Slice Quota (NSQ) service and service operations for Network Slice quota subscription, monitoring, update and notification in both, the home network and in the visiting network.

Network slice quota management during roaming

A new charging solution is proposed for D2D direct communication based on 5GS, which allows the network to charge UE's usage accurately and flexibly.

Charging in device-to-device communications over PC5 for interactive services

An object of the present disclosure is to provide an access network node, a user equipment, a network function node and a control method capable of steering a UE in connected mode. In one example aspect, a control method for an access network node includes: receiving, from a network function node for mobility management, at least one first network slice information, each of which is different from a second network slice information being used for a Protocol Data Unit, PDU, session with a user equipment, UE; and performing a redirection procedure for the UE from a first cell to a second cell which supports one of the at least one first network slice information in a case where the second network slice information is not available in the first cell.

Access network node, user equipment, network function node and control method

New methods are proposed to detect misbehaving UEs based on 5GS. The methods allow the network to react accurately and efficiently to deal with misbehaving UE(s).

Methods and devices of detection of misbehaving UEs using data analysis

The disclosure proposes solutions for network slice quota monitoring and management. It allows the Service Provider to subscribe with the 3GPP mobile network for network slice quota status notifications and retrieval and/or allows the Service Provider to allocate the initial network slice quota based on SLA (Service Level Agreement), to top-up or cut-down the allocated network slice quota when need and to re-balance it between network slices or between mobile networks.

Support for network slice quota event notification

A method performed by an operations administration and management (OAM) apparatus includes acting as a Management Data Analytics Function (MDAF) in a network. The network includes a plurality of network functions (NFs). Acting as the MDAF includes: collecting management data and network data from the network, analysing the management data and the network data, and providing a receiving entity with management data analytics service information based on the analysis of the management data and the network data.

Network data analytics for OAM

The present disclosure proposes combined registration for mobile terminals with multiple SIM subscription from the same PLMN. A mobile terminal with two or more SIM subscriptions from the same PLMN registers for all SIM subscriptions to the same AMF or for each SIM subscription, to different AMFs, or to different RATs via a single combined registration procedure. A combined deregistration procedure is also disclosed in which the UE can deregister for all SIM subscriptions in a single combined deregistration procedure.

Core network node, UE, access network node and controlling method

The current disclosure proposes per UE customization of the UE DRX/eDRX and PSM based on the analytical results from NWDAF. It also proposes a new UE policy element for UE analytics reporting—UE Analytics Reporting Policy that is a set of reporting rules and is defined by the PCF based on analytical results from NWDAF. The UEARP then is delivered or updated in the UE during registration.

Core network node and method

A method performed by a node for an Operations, Administration and Management (OAM) system includes maintaining information relating to at least one service provided by at least one node of the OAM system. The information is provided to a management function coupled to the OAM system. In this regard, the node communicates with the management function for sharing the information.

OAM functional service exposure and discovery function and data repository

A method is performed by a network function for providing data analytics services. The method includes performing data analytics based on user data for deriving a Quality of Experience (QoE) parameter for at least one user. At least one of a result of the data analytics and QoE analytics information is provided to an Operations, Administration and Maintenance (OAM) management function.

Data analytics for network automation utilizing user QoE data

User equipment performing communication with a core network node by using network slices obtained by logically dividing a network includes: means for sending information related to security of one network slice; and means for sending identity information of the one network slice in a secure method, based on a request to send information in the secure method sent from the core network node based on the sent information.

Privacy considerations for network slice selection

User equipment, UE, includes: a receiver configured to receive a parameter indicating whether the UE is restricted or authorized for transmission of user data in a message transmitted on Uplink Synchronization Channel, UL-SCH, from an access network node; and a hardware processor configured to process instructions to determine whether the transmission of the user data in the message is restricted or authorized based on the parameter.
