Methods, apparatuses, and computer program products are described that support access to multiple mutually exclusive, isolated, and/or disjointed network slices by User Equipment, UE, across one or more networks. The UE connects () to multiple network slices via a Radio Access Network, RAN, by way of one or more Radio Resource Control, RRC, connections. The RRC connections are maintained () between the UE and a respective network slice by switching the connection to inactive or idle when another RRC connection needs to be established. The UE and/or the RAN switches () an RRC connection from an inactive state to an active state based on a trigger condition such as receipt of a notification that downlink data is available over the inactive RRC connection. A Unified Data Management Function, UDM, stores and updates registration state information for the UE and multiple Access and Mobility Management Functions, AMFs.

Methods, apparatuses, and computer program products for supporting simultaneous access to mutally isolated network slices

An apparatus in a communications device supporting a plurality of different identities, the apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to: determine at least one paging overlap occasion for networks associated with the different identities; communicate the at least one paging overlap occasion determination to one of the networks associated with one of the different identities within a registration request to the one of the networks, wherein the one of the networks is caused to schedule at least one paging message to the apparatus based on the at least one paging overlap occasion determination such that the at least one paging message is scheduled at a time other than the at least one paging overlap occasion determination; and control a reception of the at least one paging message for the one of the networks such that the apparatus is caused not to listen for a paging message for the one of the networks during the determined at least one paging overlap occasion and control a reception of at least one paging message for a further one of the networks associated with the different identities during the determined at least one paging overlap occasion.

Ue assisted paging enhancements for multi-usim devices

There is provided an apparatus comprising means for receiving, at an analytics function from a first network function, a request for one or more timer adjustments for at least one timer associated with one or more network functions; obtaining, by the analytics function from one or more further network functions, one or more input parameters relating to network behaviour; and sending, from the analytics function to the first network function, an output comprising one or more timer adjustments for the at least one timer, wherein the output is based on the obtained one or more input parameters.

Method, apparatus and computer program for configuring one or more parameters associated with a network function

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

The present subject matter relates to a method comprising performing, by a user equipment, a first registration at a registration node via a first network access; performing, by the user equipment, a second registration at the registration node via a second network access. In response to determining that the user equipment is not connected to the registration node via the first network access, an update of the first registration with the registration node may be triggered, by the user equipment, dependent upon the user equipment being connected to the registration node via the second network access.
