19 Claims

1. One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a control-plane network node to:

determine to switch a user equipment (UE) from a first user plane function (UPF) node that is to anchor a first connection with a data network, wherein the first connection is associated with a first Internet protocol (IP) address or prefix;

select a second UPF node that is to anchor a second connection with the data network, wherein the second connection is associated with a second IP address or prefix; and

transmit an instruction to cause the UE to switch to the second UPF node,

wherein one or more existing traffic flows are moved from the first connection to the second connection, and the first connection at least partially overlaps, in time, with the second connection.
