Systems and methods for multi-links software-defined wide area network (SD-WAN) using phone mobile hotspots include a network device that receives, from a client, a request to establish a connection with a data source. The network device may select, responsive to receiving the request, a connection between the network device and one of the first registered cellular device or the second registered cellular device via which the network device is to transmit network traffic corresponding to the request, the first registered cellular device and the second registered cellular device registered with the network device and having a respective cellular connection. The network device may transmit network traffic corresponding to the request from the client via the connection to the data source.

Aspects of the subject disclosure may include, for example, creating a message associated with a 5th Generation (5G) wireless service, the message containing: a first indication whether the 5G wireless service is restricted or permitted in a first frequency range of a 5G frequency spectrum; and a second indication whether the 5G wireless service is restricted or permitted in a second frequency range of the 5G frequency spectrum, the second frequency range being a frequency range that is different from the first frequency range; and facilitating transmission of the message that is created to first user equipment, to a radio access network, or to a combination thereof. Other embodiments are disclosed.

A method and system for maintaining service continuity of a roaming user across multiple networks is disclosed. The method includes receiving a request for handover of the roaming user from a source network to a target network. The method includes assessing a capability of the target network to accommodate the roaming user arriving from the source network. The method includes performing a Service Level Agreement (SLA) fulfilment negotiation by the target network with the source network. The method further includes configuring the target network to facilitate the handover of the roaming user from the source network to the target network. The method includes transferring the roaming user from the source network to the target network along with the plurality of services. The method includes monitoring efficacy of the service continuity for the transferred roaming user after movement of the roaming user from the source network to the target network.

A method of radio bearer transmission in dual connectivity for a network in a long term evolution (LTE) system is disclosed. The method comprises generating at least a packet data convergence protocol protocol data unit (PDCP PDU) by a PDCP entity of the network corresponding to a radio bearer (RB), and assigning each PDCP PDU with an identity, wherein the identity indicates which PDCP entity the PDCP PDU belongs to.

In one embodiment of the present invention, a method for enabling a UDM (Unified Data Management) to perform a registration related procedure of an AMF (Access and Mobility Management Function) in a wireless communication system comprises the steps of: receiving, by the UDM, a message related to serving AMF registration of a UE, which includes access type information and ID (Identity) information, from a first AMF; transmitting, by the UDM, a deregistration related message to a second AMF when the second AMF exists, wherein the second AMF is registered as a serving AMF of the UE and related to the access type information.
