Abstract

Embodiments of the present disclosure provide methods and apparatuses for configuring QoS in a communication network. A method performed by a first network node in a first communication network, includes transmitting, to a second network node in a second communication network, a first message including quality of service (QoS) constraints configured for the first communication network; receiving, from the second network node, a second message including a first QoS configuration, wherein the first QoS configuration includes at least one QoS parameter authorized in the second communication network; and enforcing a second QoS configuration in the first communication network, wherein the second QoS configuration is based on the first QoS configuration and/or the QoS constraints. The QoS constraints and previously authorized QoS configuration can be exchanged between different network nodes, even different networks. Therefore, the service quality and/or continuity related to QoS configuration may be ensured.
