Abstract
The present disclosure relates to a method performed by a network element (5) in a Policy Control and Charging (PCC) system (2) in a communication network (1). The method comprises establishing a first Internet Protocol (IP) Connectivity Access Network (CAN) session with a first Policy and Charging Enforcement Function (PCEF) 4x in the PCC system, the first PCEF being associated with a first Public Data Network (PDN) connection X between a Multi-Path Transmission Control Protocol (MPTCP) capable radio device (6) and an MPTCP proxy (8). The method also comprises establishing a second IP-CAN session with a second PCEF 4y in the PCC system, the second PCEF being associated with a second PDN connection Y between the radio device and the MPTCP proxy. The method also comprises establishing a third IP-CAN session with a third PCEF 4z in the PCC system, the third PCEF being associated with an IP connection Z between the MPTCP proxy and a PDN 7, the IP connection being configured for carrying data from both the first PDN connection and the second PDN connection. The method also comprises establishing a fourth IP-CAN session with a Policy and Charging Rules Function (PCRF) 3 in the PCC syste…
