An authentication server () in a home network () of a wireless device () receives, from a network node (), a request () for authentication data () based on which to authenticate the wireless device (). The request () indicates a serving network () on which the authentication data () is to be based. The authentication server () checks whether or not the network node () is authorized to request authentication data () that is based on the indicated serving network ().

Authentication of a wireless device in a wireless communication network

Systems and methods are described for redirecting a user equipment with a routing misconfiguration. An exemplary method includes detecting a potential misconfiguration associated with the user equipment or a subscriber identity module (SIM) associated with the user equipment and generating an error code indicating the potential misconfiguration associated with the user equipment of the SIM associated with the user equipment. The error code is transmitted to an authentication module and indicates that the misconfiguration is an incorrect routing identifier and includes additional user information.

Embodiments include methods performed by a service consumer network function (NF) of a communication network. Such methods include sending, to a network repository function (NRF) of the communication network, a request for an access token for notifications from a service producer NF of the communication network. The request includes a list of alternative notification endpoints. Such methods also include receiving, from the NRF, an access token for the notifications from the service producer NF. The access token includes the list of alternative notification endpoints. Such methods also include sending, to the service producer NF, a subscription request for the notifications. The subscription request includes the received access token, a primary notification endpoint, and binding information usable for selecting an alternative notification endpoint from the list. Other embodiments include complementary methods performed by NRFs and service producer NFs, as well as network nodes/functions that perform such methods.

Authorization of consumer network functions

A method by a network function communicating with a unified data repository of a communications network. The method including receiving from the UDR a subscription identifier for a subscription by the network function to receive data change notifications from the UDR. The method also including sending toward the UDR a change request containing an instruction to change data in the UDR and containing the subscription identifier to signal the UDR to not send to the network function a notification regarding this change to the data.

Change request with indication that no notification of subscribed data change is to be sent to requesting network function

Apparatuses and methods for short message service (SMS) delivery are disclosed. In one embodiment, a method implemented in a data management (UDM) node includes receiving, by the UDM node, a registration request from a home subscriber server, HSS, node, the registration request being to register an Internet Protocol-Short Message-Gateway, IP-SM-GW, and the registration request comprising an address of the IP-SM-GW; and optionally, as a result of receiving the registration request comprising the address of the IP-SM-GW from the HSS node, determining message waiting data. In one embodiment, a method implemented in a HSS node includes receiving a registration request; and sending, to a unified data management, UDM, node, the registration request, the registration request being to register an Internet Protocol-Short Message-Gateway, IP-SM-GW, and the registration request comprising an address of the IP-SM-GW.

Support of short message service over internet protocol (SMSoIP) in 5G-only deployments

There is provided mechanisms for enabling selection of service-providing NFs in a 3GPP communication network. A method is performed by an NRF. The method comprises obtaining one register request from each of the service-providing NFs. Each registration request comprises an NF profile. Each NF profile comprises a security setting attribute. The method comprises storing the NF profiles of the service-providing NFs. The method comprises obtaining a discovery request from a service-requesting NF. The request indicates an NF type. The method comprises providing a discovery response to the service-requesting NF. The discovery response comprises the NF profile of at least one of the service-providing NFs of the NF type, thereby enabling selection of the service-providing NFs. The security setting attribute may pertain to support for mutual TLS and/or for use of OAuth-2 based authorization.

Selection of service-providing network functions in a 3GPP communication network

Embodiments described herein relate to methods and apparatuses for registering one or more services that a producer network function is capable of providing at a network repository function and allowing for the access of those services by consumer network functions. A method in a producer network function comprises transmitting a registration request to the NRF, wherein the registration request comprises registration information comprising: an indication of the one or more services; and an indication of resources and operations associated with each resource of the one or more services that are allowed per network function consumer type.

Registering and requesting services in a service based architecture

The invention relates to a method for operating a tracking entity () configured to track to which access and connectivity management entity () a mobile device () is connected in a mobile communications network, wherein an application server () is initiating a monitoring of an event occurring at the mobile device, the method comprising: —receiving a request to monitor the event at the mobile device (), the request comprising an indication for an audit for the monitoring of the event by which a validity of the monitoring of the event should be checked when the event has not been detected for an indicated period of time, —transmitting the received request for the event with the indication for the audit and the indicated period of time to the access and connectivity management entity () to which the mobile device is connected, —receiving a notification from the access and connectivity management entity () that the event has not been detected for the indicated period of time, —determining, in response to the received notification, based on information available in the tracking unit whether the monitoring of the event should be continued or not.

Audit process for the monitoring of events

Selecting a serving session control node in an Internet Protocol, IP, Multimedia Subsystem, IMS, telecommunication network, for a User Equipment. The method includes receiving, by an interrogating session control node, a Session Initiation Protocol, SIP register message for registering said UE in said IMS telecommunication network, the SIP register message has a UE capability feature mappable to a UE initiated server capability for the serving session control node, transmitting, by the interrogating session control node, to a Home Subscriber Server, a user authorization request message comprising the UE capability feature, receiving, by the interrogating session control node, from the Home Subscriber Server, a user authorization answer message including one or more UE initiated server capabilities for a serving session control node, selecting, by the interrogating session control node, a serving session control node based on the one or more received UE initiated server capabilities in the user authorization answer message.
