Abstract
The embodiments herein relates to a method for enabling multiple bearer support upon congestion situations in a communication network. The PCC architecture is enabled to determine whether separate bearers need to be established for service(s) that demand MBR>GBR when no ECN support is provided. This is provided in nodes and methods receiving, using a receiving unit (301), an indication of session establishment for a bearer from a bearer binding function unit (113, 115), obtaining profile information with Quality of Service, QoS, information about maximum bit rate, MBR, and guaranteed bit rate, GBR, related to the bearer; determining that the MBR is larger than the GBR, making a policy decision, and transmitting, using the transmitting unit (305), an acknowledgement of session establishment to the bearer binding function unit with an indicator that a separate bearer is to be established.
