Techniques for inserting a new node into a communications path of existing nodes of a 3GPP network are described herein. According to one embodiment, state information is captured within a transport protocol layer of a first node. The state information pertains to an existing communications session between a second node and a third node, while the first node routing packets exchanged between the second and third nodes via the existing communications session. The transport protocol layer of the first node is then configured using the captured state information to enable the transport protocol layer of the first node to independently communicate with a transport protocol layer of the second node and the third node respectively without terminating the existing communications session.
