A first device can send a first message comprising a device identifier. A second device can receive the first message. The second device can send the device identifier and first metadata to a server, wherein the first metadata is associated with the second device. The server can receive the device identifier and the first metadata. The server can further send the device identifier and first metadata to a third device.

There is disclosed a method, for a UE, for performing a Network Slice-Specific Authentication and Authorization (NSSAA) procedure in a network comprising the UE and a first network entity. The method comprises: in response to transmitting, to the first network entity, a first message for initiating a first procedure, receiving, from the first network entity, a second message; determining whether a first condition is satisfied, the first condition comprising: the second message includes a predefined indication; and determining whether to block or restrict one or more second procedures based on the first condition.

A disclosure of the present specification provides a method of performing communication related to a network slice by a network node. The method may comprise the steps of: receiving a registration request message from a UE; determining, on the basis of information on a network slice, whether the UE is allowed to access the network slice; and when it is determined that the UE is not allowed to access the network slice due to a network slice limit control, transmitting, to the UE, a registration acceptance message including information on a waiting network slice.

Systems and methods for signaling information related to wireless device positioning in a cellular communications network are disclosed. In some embodiments, a method of operation of a first network node for signaling information related to wireless device positioning in a cellular communications network comprises signaling, from the first network node to a second node, information comprising information that relates to a new vertical surface model for a plurality of cells in a cellular communications network. The new vertical surface model is a translated and scaled version of an initial vertical surface model.

An application function node (10) includes a control unit (13). The control unit (13) acquires session information regarding a PDU session from a UDM node (30), determines, from a plurality of the PDU sessions, a first PDU session for maintaining communication and a second PDU session for stopping communication based on the session information, and requests to stop communication in the determined second PDU session.

A method of provisioning an electronic subscriber identity module (eSIM) to a wireless communication device. The method comprises provisioning an eSIM profile into an eSIM of a virtual eSIM provisioning platform provided by a computer system and where the eSIM profile comprises wireless communication service provider data and wireless communication service subscriber data, partitioning by an eSIM provisioning application a process of writing the eSIM profile to an eSIM of a wireless communication device into a plurality of messages, whereby the complexity of provisioning the eSIM profile to the eSIM of the wireless communication device is handled by the intelligence of the eSIM provisioning application, establishing wireless communication by the eSIM provisioning application with a wireless communication device having an eSIM, and sending the messages by the eSIM provisioning application to the eSIM of the wireless communication device.

A RAN node (2) receives, from a core network node (6, 7, 8), a first identifier that is used by a service, an application, or an edge server (5) to identify a radio terminal (1) connected to the RAN node (2), and associates the first identifier with a second identifier that is used by the RAN node (2) to identify the radio terminal (1). Further, the RAN node (2) communicates with the edge server (5) using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.

Provided are a network data collection method, device and system. The network data collection method includes the following. A source Network Data Analytics Function (NWDAF) sends a network function data collection request to a target NWDAF, where the network function data collection request includes a data collection assistance parameter of at least one network function from which data collection is requested. The source NWDAF receives a network function data collection response sent by the target NWDAF, where the network function data collection response includes network data fed back by the at least one network function.
