Summary

Interworking capability is an essential function to support quality of service (QoS)-guaranteed data transmission across heterogeneous networks. The data transmission of deterministic communication services in local networks usually involves multiple technology domains. In order to provide an efficient QoS guarantee for deterministic communication services in heterogeneous technology domains, this Recommendation defines three types of interworking capability and specifies QoS assurance requirements, framework instances and operational procedures of interworking capabilities, based on the models defined in Recommendation ITU-T Y.3121.
