ABSTRACT:
A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. Flow identifier information such as a 5-tuple is generated for a signaling IP flow and a media IP flow so as to unify a mechanism for reporting a signaling path status and a mechanism for reporting a bearer event of a media IP flow, so that the mechanism for reporting a signaling path status is not limited by the parameter of Flow Usage, the PDP context with a signaling tag, thereby establishing corresponding PCC rules for signaling and the association between a signaling IP flow and a bearer. A method for reporting a signaling path status is further provided in the invention. In the method, for a default PDP context or a PDP context of a signaling IP flow, the predefined PCC rules are activated or signaling PCC rules generated in accordance with an Application Function address are installed, thereby an IP signaling path status is reported in accordance with rule names of the predefine PCC rules or the signaling PCC rules.
