723, PDSN starts after the gate, by send the PMIP message of expansion to LMA, comprises gate log-on message and charging in the message, triggers LMA and starts gate, and implement to charge.

724, LMA receives after gate log-on message and the charge information, returns expansion PMIP response message to PDSN.

725, LMA starts charge information request message by chargeing and sends to AAA, starts the charging process at business.

726, guarantee that when having set up corresponding to assistant service is connected, and start after the gate that MS just can commence business with the required QoS of business datum flow transmission.H-AAA charges to service implementation accordingly according to the charging initiation message.

What the foregoing description was described is to adopt the CDMA2000 of PMIP agreement to introduce after the PCC charging implementation process.Wherein by the PMIP message of LMA by expansion from the PDSN collecting charging information, and receiving the gate incident after and AAA charge alternately, startup is at the charging process of business.Other charging scenes of the CDMA2000 of employing PMIP agreement are similar to embodiment 1-4, no longer describe here.

The present invention also provides a kind of dynamic strategy control charging realization system down, it is characterized in that, comprises home agent (HA) or local mobile grappling (LMA), is used for collecting charging information, and described charge information is sent to AAA, and control reciprocal process realizes chargeing.

Wherein, described HA or LMA are used for obtaining charge information by PCRF from PDSN, and perhaps HA is by expansion MIP agreement, and LMA obtains charge information by expansion PMIP agreement from PDSN.

Wherein, described HA or LMA are used for after receiving the control strategy information that PCRF issues charge information being sent to AAA, and control reciprocal process realizes chargeing; Perhaps after receiving the gate incident, charge information is sent to AAA, control reciprocal process realizes chargeing.

Wherein, described HA or LMA are used for receiving described gate incident by PCRF from PDSN, and perhaps, HA is by expansion MIP agreement, and LMA receives described gate incident by expansion PMIP agreement from PDSN, and described gate incident is that gate is opened or gate is closed.

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
