METHOD, APPARATUS, AND SYSTEM FOR THE MGC DISTRIBUTING A RESOURCE PROVISION DECISION TO THE MG

摘要

A method for a media gateway controller (MGC) to deliver a resource provision decision to a media gateway (MG) includes: the MGC receives a decision request from the MG and makes a resource provision decision according to service requirement information and/or resource status information, and delivers the resource provision decision to the MG. The present invention also discloses an MGC, an MG and a system comprising the MGC and MG. In the invention, the MGC does not deliver the resource provision decision already made according to service requirement information and/or resource status information until reception of a decision request from the MG so that the MGC delivers a resource provision decision passively upon request of the MG. The Pull mode for delivery of the resource provision decision is thus supported.
