Abstract
In one example, a User Plane Function (UPF) in a Visited Public Land Mobile Network (V-PLMN) that includes a first network and a second network obtains network traffic from user equipment via the first network. The UPF provides the network traffic obtained via the first network to a data network with an Internet Protocol (IP) address allocated to the network traffic obtained from the user equipment. In response to a handover of the user equipment from the first network to the second network, the UPF obtains the network traffic from the user equipment via the second network. The UPF provides the network traffic obtained via the second network to the data network with the IP address.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
