Abstract:
Data forwarding may be useful in many communication systems. Thus, for example, data forwarding support may be useful in dual connectivity in, for example, the third generation partnership project (3GPP) and more particularly to dual connectivity with enabled downlink (DL) data back forwarding. A method can include receiving, by a first network node, an indication indicating that for at least one split bearer, data received prior to the indication is to be forwarded to a second network node. The indication can also indicate that the at least one split bearer should be kept or maintained at the first network node. The method can also include, in response to the received indication, forwarding the data for the at least one split bearer received prior to the indication to the second network node.
