Methods and apparatuses for improving service continuity are disclosed. The solution comprises storing () information slice remapping describing how a given net-work slice may be mapped to another network slice, receiving () a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node and transmitting () based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping and/or activity status of the packet data unit sessions associated with the slice not supported by the node.

Improving service continuity

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

Embodiments of the disclosure provide a method, device and computer readable medium for coordination between wireline and wireless policy controllers. According to embodiments of the present disclosure, the service controller is able to coordinate between information about a wireless subscription for mapping from a traffic multiplexer used in a wireline access to a wireless data session selector and information sent to a wireline Residential Gateway device about mapping application traffic to a traffic multiplexer used in a wireline access.

Coordination between wireline and wireless policy controllers

Embodiments of the present disclosure relate to dynamical changes in access and mobility policies. According to embodiments, an Application Function entity can request the Access and Mobility related entity to modify the access and mobility policies for a terminal device after the discovery of the Access and Mobility related entity. Alternatively, the Access and Mobility related entity obtains access and mobility policies from a User Data Repository that link traffic of an application on a Session towards to access and mobility policies and configure the AM policy based on a detection of traffic change done under control of a Session Management related entity. Therefore, the access setting and/or the mobility setting can be dynamically changed based on the traffic change in the application.

Dynamical change in access and mobility policy

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

There is provided a method, apparatus and computer program product for causing a network repository function to perform: receiving, from a network function service consumer, an access request for an access authorization token, the request comprising a first identification of the network function service consumer and a first identification of at least one network slice on which access is requested; generating an access token in response to the request, the access token comprising at least one network slice identifier for the at least one network slice identified by the first identification; and providing the generated access token to the network function in response to the request for an access authorization token.

Apparatus, methods, and computer programs

According to certain embodiments, a terminal device may receive location service user plane (LCUP) assistance information in a control plane (CP) positioning protocol signaling. The LCUP assistance information includes at least one of addressing information of an LCUP function instance, and security information for establishing an user plane (UP) session between the terminal device and the LCUP function instance. The LCUP function instance is associated with a location management function (LMF) selected for serving the terminal device. The terminal device can establish a secured UP connection between the terminal device and the LCUP function instance using the LCUP assistance information so as to perform a UP positioning operation using the LCUP function instance. The terminal device can ensure the UE establishes a secured connection with the LCUP associated with the serving LMF, thereby CP location operation through the UP interaction between the terminal device and the LUCP associated with LMF.

Location service enhancement based on usage of an user plane interface with a terminal device

There is provided a computer program, method and apparatus for an application function that causes the application function to: signal, to a first network function, a first request to be notified of at least one change in first user plane functions associated with a first virtual network, the first virtual network comprising the first user plane functions and a first interface interfacing the first user plane functions with a first data network; receive, from the first network function, a first indication that said at least one change has occurred; and configure connectivity with at least one interface to the first virtual network in dependence on the at least one change indicated in the said first indication.

Method to update 5G VN group topology update to AF for efficient network management

A method, apparatus and computer program product receive a traffic redundancy indication from a user equipment in a communication network or from a policy controller. The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.

Method and apparatus for redundancy improvement in a communication system

Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) on the path are provided. The method may include determining that an existing user plane function is sub-optimal in terms of routing and latency incurred with respect to traffic for a given packet data unit session of a user equipment. The method may also include establishing, based on the determination, a new user plane function for the packet data unit session. The method may further include establishing a branching point user plane function that interfaces with the existing user plane function, the new user plane function, and a plurality of network access types. In addition, the method may include updating the user equipment by providing the user equipment with relevant multi-access traffic steering rules.

Multiple user plane function supporting access traffic steering, switching, and splitting for multi-access packet data unit session

It is provided a method comprising: inquiring a repository function to provide identifications of all producers registered in the repository function and satisfying a query condition; receiving or obtaining the identifications of all the producers registered in the repository function and satisfying the query condition upon the inquiring; requesting, using the received or obtained identifications, each of the producers to provide a service.

Communication between CN and AN

Methods and apparatuses for edge services are disclosed. A network function entity receives from an application function entity a request relating to a data communication session, and can then determine, in response to the request, information of at least one local network exposure function entity for the application function entity. The application function entity is provided with the information of the at least one local network exposure function entity. The information can be used in connecting with a local network exposure function entity. The local network exposure function entity can then be used for the data communication session.
