This specification describes the functional requirements and information flows that generate procedures between the Multimedia Resource Function Controller (MRFC) and the Multimedia Resource Function Processor (MRFP), the Mp Interface.

This specification is limited to information flows relevant to the Mp Interface; in order to define these procedures and make the functional requirements clear some triggers from an external interface may be described; these may be specified within the Mr interface for example or within an AS in which the MRFC function resides.

The protocol on the Mp interface is defined to comply with ITU-T H.248.1 Gateway Control Protocol. The goal of this specification is to provide the input to defining a formal Profile within the H.248 protocol toolbox specifically for the Mp application.
