In some implementations, a first network device may receive an authorization request associated with a user device connecting to a network associated with first network device. The first network device may redirect the authorization request toward a second network device associated with a second service provider. The first network device may determine, based on a response to the authorization request, that the user device is subscribed to a service provided by the second service provider and that the user device is not authorized to connect to the network. The first network device may provide a temporary service to the user device to enable the user device to connect to the network for a limited period based on the user device being subscribed to the service provided by the second service provider and the user device not being authorized to connect to the network.

Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.

An apparatus and method are provided for steering a PDU session associated with traffic routed to a selected UPF. The method includes receiving, from an AF entity, a first message including information for selecting a UPF entity for traffic routing of a terminal and information on a spatial condition associated with a location of the terminal; transmitting, to an SMF entity, a second message to receive information associated with the location of the terminal indicating that the terminal entered or left a specific area, the specific area being determined by the PCF entity based on the spatial condition; receiving, from the SMF entity, a third message including the information associated with the location of the terminal; and transmitting, to the SMF entity, a fourth message based on the information associated with the location of the terminal included in the third message, the fourth message including the information for selecting the UPF entity for traffic routing of the terminal.

A device-communication system may receive, from a user device via a first network, communication data originating from a first device connected to the user device via a second network having a type different from that of the first network. The device-communication system may process the communication data to determine a corresponding device-management system, and may communicate further with the user device for additional identification information, if necessary. The device-communication system determines which of a plurality of device-management systems should receive the communication data and sends the data to the appropriate system.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution. Methods and systems for mitigating Denial of Service (DOS) attacks in wireless networks, by performing admission control by verifying a User Equipment's (UE's) registration request via a Closed Access Group (CAG) cell without performing a primary authentication are provided. Embodiments herein disclose methods and system for verifying permissions of the UE to access a CAG cell based on the UE's Subscription identifier, before performing the primary authentication. The method for mitigating DOS attacks in wireless networks includes requesting a public land mobile network for accessing a non-public network (NPN) through a CAG cell, verifying the permissions of a UE to access the requested NPN through the CAG cell, and performing a primary authentication.
