ITU-T H.248.55 PDF

There are various resource control mechanisms used in next generation networks (NGNs) such as those described in [ITU-T Y.2111]. A policy control mechanism (such as QoS resource control) is described by this Recommendation. The mechanism itself may result in different control scenarios that are primarily dependent on dedicated user and customer premises equipment (UE, CPE) types. This Recommendation describes how H.248 entities behave in such a network environment, and defines an H.248 package, which may be used in a specific resource control scenario.

Clause 6 provides a background on resource and admission control functions (RACFs) and discusses the resource control modes. The clause then focuses on the "pull mode" of resource control and provides a mapping of the RACF functions and flows of this mode to the H.248 architecture.
