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

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

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

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.

System and method for network automation in slice-based network using reinforcement learning

A method is performed by a user equipment (UE). The method includes transmitting, to a network, a message for registration of the UE, the message having single network slice selection assistance information (S-NSSAI) that is configured to be added to at least one allowed network slice selection assistance information (NSSAI) after an authentication at an access and mobility management function (AMF). The method also includes receiving, from the AMF, a registration accept message having the at least one allowed NSSAI that includes the S-NSSAI for which the authentication has been completed.

Isolated network slice selection

A method performed by a network node includes receiving a service request for requesting a communication for a user equipment (UE). The service request includes information identifying a service type associated with the requested communication. It is determined whether to reject the service request based on the service type associated with the requested communication.

Service types and congestion control

A Network Data Analytics Function, NWDAF, includes: means for receiving analytics information regarding cell re-selection by User Equipment, UE, among cells; and means for notifying another network node of matching the analytics information with an exception so that the other network node takes actions for solving the exception.

Network data analytics function, access and mobility function, and control method for UE analytics assistance for network automation and optimisation

A core network node for mobility management includes a means for transmitting information related to expected mobility of user equipment, UE, to an access network node.

RRC inactive state optimization

A method is performed by a user equipment (UE). The method includes transmitting, to a network, a message for registration of the UE. The message comprises information related to one or more network slices that are not compatible with at least one allowed network slice.

A method for supporting wireless connectivity of a mobile station to a cellular network, wherein the mobile station is located within the coverage area of a femtocell base station of which it is a non-CSG mobile station, and wherein the mobile station experiences interference which it indicates to the femtocell base station, is characterized in that the femtocell base station, upon receiving the experienced interference indication from the non-CSG mobile station, triggers the non-CSG mobile station to report interference related information, wherein, based on the interference related information, the femtocell base station performs a first check whether it is originator of the interference experienced by the non-CSG mobile station. Furthermore, a corresponding femtocell base station for supporting wireless connectivity of a mobile station to a cellular network is disclosed.
