摘要

There is provided a method of operating a source node (10) in a first network that is operating according to a first radio access technology, RAT, wherein a terminal device (12) has one or more tight aggregation bearers through the source node (10) and a first node (14) in a second network that is operating according to a second RAT, the method comprising on or during handover of the terminal device (12) from the source node (10) to a target node (11) in the first network, sending information to the first node (14) or a control node (40) in the second network for the first node (14) for use in enabling the tight aggregation to be established through the target node (11) and the first node (14) following the handover.
