A device associated with a home network may receive an access point name (APN) request from a device associated with a visitor network, wherein the APN request is associated with a user device. The device associated with the home network may cause, based on the APN request, a virtual home network to be instantiated that includes a virtual gateway, wherein the virtual home network is physically closer to the user device than the home network. The device associated with the home network may generate an APN that identifies the virtual home network and the virtual gateway. The device associated with the home network may cause the APN to be sent to the device associated with the visitor network to cause a gateway associated with the visitor network to connect to the virtual gateway.

A communication apparatus comprises a radio transceiver and a modem processor. The radio transceiver is configured to transmit or receive wireless signals in a wireless network. The modem processor is coupled to the radio transceiver and configured to perform operations comprising: connecting to a first network device via a first communication link in a first frequency band; predicting a handover according to at least one of at least one measurement result or location information; connecting to a second network device via a second communication link in a second frequency band, after predicting the handover; performing the handover from the first network device to a third network device, to stop connecting to the first network device and to connect to the third network device via the first communication link in the first frequency band; and stopping connecting to the second network device, after performing the handover.

A method, apparatus and computer program product are provided to facilitate interworking a plurality of cellular radio access networks and wireless local area networks (WLANs). In the context of a method, a set of information is maintained for a plurality of different cellular radio access networks that defines a relative priority of selection among the cellular radio access networks. The method also includes maintaining wireless access selection information defining a relative priority of selection among one or more WLANs relative to the cellular radio access networks. The method also permits the relative priority of the WLANs to be modified without modification of the set of information. For example, the relative priority the WLANs may be modified in a manner specific to the user equipment or specific to a cell. The method may also include causing notification to be provided to user equipment of the set of information and the wireless access selection information.

The present disclosure provides methods for signaling QoS Flow control parameters, and corresponding NF entities. The method comprises generating one or more data flow rules associated with a QoS Flow and a QoS Flow profile. The data flow rules include parameters specific to a data flow that belongs to the QoS Flow, while the QoS Flow profile includes parameters that are common to all data flows that belong to the same QoS Flow. The present disclosure further discloses a corresponding method of receiving the QoS Flow control parameters. The present disclosure further provides corresponding computer readable medium.

A control system enables re-registration of user equipment (UE) on an alternative network in the event of a partial failure of a network (VPLMN) for wireless communication. An access and mobility management function (AMF) manages the communication to user equipment (UE) via network slices (1,2,3). A slice priority management function (SPM) receives data indicative of a change in the network's ability to maintain the instantiated network slices and determines to reduce services via affected network slices. Before said slice reduction, the access and mobility management function is informed and sends a slice reduction message to the user equipment. In the UE an alternate network selection function (ANSF) receives the slice reduction message and selects an alternate network based on the user information (USIM) and the slice reduction information, and triggers registration on the selected alternate network for transferring at least part of the affected services to a network slice of the selected alternate network.
