1. A method for use by a network node in a Radio Access Network (RAN), the method comprising:
establishing a first Stream Control Transmission Protocol (SCTP) association for an application protocol connection with a core network node;
establishing a second SCTP association for the application protocol connection with the core network node;
establishing a third SCTP association for the application protocol connection with the core network node, wherein the first and second SCTP associations are dedicated to one or more UE associated signaling streams and the third SCTP association is dedicated to a non-UE associated signaling stream; and
moving a user equipment (UE) associated signaling stream from the first SCTP association to the second SCTP association.
