Abstract: 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.

Abstract: 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).

Abstract: The disclosure is addressing the 3GPP and GSMA requirements for compatibility restrictions between certain network slices. It proposes solutions for management, control and enforcement of the constraints for simultaneous usage of certain network slices in the UE (3) and in the network. This allows for different level of isolation between the network slices leading to improved security and integrity in the data exchange.

Abstract: 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.

Abstract: 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.

Abstract: A user equipment (UE) includes a transceiver and a processor. The transceiver is configured to receive, from a network, a paging message including an indication for delayed paging. The indication for delayed paging indicates that the UE is allowed to delay a response to the paging message. The processor is configured to identify the indication for delayed paging in the paging message.

Abstract: A method for a User Equipment (UE) (500) comprises performing registration procedure to 5G System (5GS); receiving at least one of area restriction related information indicating at least one of allowed area and not allowed area, wherein the area restriction related information is at least one of per Single Network Slice Selection Assistance Information (S-NSSAI) basis, per Access Point Name (APN) basis, and per S-NSSAI and APN basis; and determining whether or not to transmit a Protocol Data Unit (PDU) session related signaling based on the area information; wherein the UE (500) transmits the PDU session related signaling when the UE (500) enters Tracking Area (TA) present in the allowed area or when the UE (500) does not enter TA present in the not allowed area.

Abstract: 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.

Abstract: An operations, administration and maintenance (OAM) function provides service level specification (SLS) assurance by executing a method. The method includes: determining at least one policy for SLS assurance for a user equipment (UE) to be used in automatic quality of experience (QoE) measurement reporting, the at least one policy comprising an associated QoE measurement reporting criterion and a reporting format; and transmitting the at least one policy towards the UE.

Abstract: A method for facilitating allocation of network resources to at least one slice in a communication network includes obtaining information identifying a mapping between network resource allocations and a respective quality of experience (QoE) associated with a user and obtaining information relating to a quality of service (QoS) tolerance for a particular QoE. The method includes providing to a controller for allocating at least a portion of the network resources to the at least one slice: i) the information identifying a mapping between network resource allocations and a QoE; ii) the information relating to the QoS tolerance; and iii) information identifying a current QoE and a target QoE associated with at least one user.

Abstract: 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.

Abstract: The current disclosure proposes URLLC support indication exchange between the network nodes and URLLC support by the network indication in the Registration procedure so that a URLLC capable UE knows whether it could initiate URLLC type of PDU session establishment.
