Systems, methods, apparatuses, and computer program products for determination of non-3GPP interworking function(s) (N3IWFs), which support slices targeted by a device or user equipment (UE), are provided. One method may include transmitting, by a UE or device, a request to at least one network node. The request may be to obtain information on network slices supported by at least one N3IWF. The method may also include receiving, from the at least one network node, a response comprising information for one or more N3IWFs and, based on the received information for the N3IWF(s), selecting one of the N3IWF(s) to use to connect to a 5G core network (5GC).

Methods and apparatuses for determination of non-3GPP interworking function (N3IWF)

Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart are provided. For example, a method may include detecting non-functionality of a first multicast/broadcast user plane function that was supporting a packet forwarding control protocol session context for a multicast/broadcast session. The method may also include reselecting a second multicast/broadcast user plane function. The method may further include recreating a packet forwarding control protocol session context in the second multicast/broadcast user plane function for said multicast/broadcast session. The method may additionally include receiving new addressing information for the delivery of said multicast/broadcast session data from said second multicast/broadcast user plane function. The method may also include updating a network element with the new addressing information.

Restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart

Systems, methods, apparatuses, and computer program products for distributing multicast packets in individual protocol data unit (PDU) sessions are provided. One method may include receiving, at a user plane node, a request from a session management node, to receive packets for a multicast session and/or to send packets from the multicast session within a protocol data unit (PDU) session. The method may also include determining whether the user plane node was already configured to receive incoming packets for the multicast session, and informing the session management node as to whether the user plane node was already configured to receive the incoming packets for the multicast session.

Distributing multicast packets in individual protocol data unit (PDU) sessions

Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast failure with restart are provided. For example, a method may include detecting a restart of a multicast/broadcast user plane function that was supporting a packet forwarding control protocol session for a multicast/broadcast session. The method may also include re-creating a packet forwarding control protocol session for the multicast/broadcast session. The method may further include providing addressing information for the data delivery of the broadcast/multicast session to the multicast/broadcast user plane function and instructing the multicast/broadcast user plane function to use this addressing information for the broadcast/multicast session if possible.

Restoration of multicast/broadcast service upon multicast/broadcast failure with restart

Methods and apparatus, including computer program products, are provided for ping pong detection. In some example embodiments, there may be provided a method that includes subscribing to an event at one or more access and mobility management functions, the event indicative of a frequent mobility of a user equipment between different access and mobility management functions; and receiving, from an access and mobility management function, a notification of the subscribed event. Related systems, methods, and articles of manufacture are also described.

Detecting UE ping-ponging between different network nodes

Apparatuses and methods for providing services in a communication system are disclosed. A request for a service provided by a service function entity in a network system is received, wherein the request indicates an identity of a user for which the service is requested. An identity of a group of service function entities capable of serving the user and determined based on the identity of the user is then provided, and an indication of the determined identity of the group is sent in the response for subsequent use by the sender of the request and/or at least one other entity involved in requests for services associated with the user.

Group identities in a communication system

It is provided a method comprising at least one of a) and b): a) monitoring whether a service request to produce a producer service is received and producing the producer service if the service request is received, wherein the producer service is a service produced by the access network; and b) consuming a producer service from a core network or an access network, wherein the producer service is consumed by an access network.

Access network with service-based interfaces

Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for hop-by-hop security. A proposed method comprises receiving, at a first apparatus and from a second apparatus associated with a first network function, a message directed from the first network function to a second network function, the message comprising a first signature and network function information, the network function information at least comprising identification information of the first network function; in accordance with a successful validation of the first signature, updating the message with a second signature specific to a service communication proxy implemented by the first apparatus; and transmitting the updated message to a third apparatus associated with the second network function, the updated message comprising at least the second signature and the network function information.

Enhanced hop by hop security

According to an example aspect, there is provided a method, comprising: receiving, by a service communication proxy from a network function consumer, a service request for a service by a network function producer, transmitting, in response to an error in obtaining an access token from a network repository function on the basis of the service request, a response to the service request to the network function consumer, wherein the access token is for authorizing access to a service at the network function producer and the response is indicative of an access token error.

Network function request error handling

An apparatus and method can include monitoring whether a consumer of a target network receives a resource identifier, a first apiRoot identifying a producer, and a second apiRoot identifying the producer and a producer network. The first apiRoot is for routing a service request to the producer, and the second apiRoot is for routing the service request to the producer if the target network is different from the producer network. The method further comprises identifying the producer network based on the second apiRoot, and deciding whether the target network is different from the producer network. If the target network is not different from the producer network, the service request is sent wherein the resource is identified by the first apiRoot and the identifier. If the target network is different from the producer network, the service request is sent wherein the resource is identified by the second apiRoot and the identifier.

NF service producer's URIs for inter-PLMN mobility

There is provided a method, computer program, and apparatus for a network repository function that causes the network repository function to: alter, for a second network function, a value of an attribute in a network profile associated with said second network function; and signal, to a first network function, an identifier for said second network function in addition to an said altered value of said attribute, based on a first request for discovery from said first network function, wherein said network profile comprises an indication of a service and/or an attribute of said second network function.
