In the prior art, stipulated in the agreement 29213 that the more new technological process of being initiated by strategy and charge execution function (PCEF, Policy and Charging Enforcement Function) is as shown in Figure 2, step comprises:
Step 1, gateway (GW, Gate Way) receive that IP-CAN carries the signaling of the request PCC rule that triggers, to initiate the modification of IP-CAN session.This signaling as far as GPRS, can be the Update PDP Context Request request message that gateway GSN (GGSN, Gateway GSN) receives because of the type of IP-CAN session is different.
Step 2, (CCR, Credit-Control-Request) message comes notification strategy and charging rule functions (PCRF, Policy and Charging Rules Function) to revise the IP-CAN session to GW through sending credit control request.Wherein, the CC-Request-Type AVP among the CCR is set to UPDATE_REQUEST.With regard to GPRS,, need carry this bearing identification among the CCR so, to inform this renewal of PCRF and this bearing association if the carrying that only limits to of the request of upgrading takes place.Otherwise, think that this upgrades the scope of application is entire I P-CAN session.
Step 3, the CCR message that the PCRF storage is received.
Step 4, PCRF with the IP-CAN binding session to the application layer conversation of any existence.
Step 5, if the user signing contract information that PCRF need be correlated with, and when SPR does not provide before, just to the SPR initiation request to obtain user signing contract information.
This step is an optional step, in Fig. 1, dots, and in the following description, every flow process that dots in the flow chart 1 representes that this flow process is optional flow process; The flow process of using solid line to represent is necessary flow process.
Step 6 after SPR receives the user signing contract information request, is returned corresponding response message to PCRF, carries PCRF requesting users CAMEL-Subscription-Information in the message.
Step 7, if the modification of this IP-CAN session needs to report the AF session that is associated, PCRF will send RAR (Re-Auth-Request) request message to AF, the Specific-Action AVP of message is set to the trigger event of initiation request.
Step 8, if step 7 takes place, AF returns to the RAA response message that one of PCRF carries update service information, wherein comprises business information (like the IP address of IP stream, port numbers, media type information etc.).
Step 9, PCRF formulates a new PCC rule and an installation based on the business information of receiving, CAMEL-Subscription-Information, operator's configuration etc.
Step 10, PCRF preserves the said PCC rule of formulating.
Step 11, PCRF issues said PCC rule through credit control response CCA (Credit-Control-Answer) message, also possibly carry QoS information in the message simultaneously.
Step 12, can GW installs the PCC rule of receiving, implements to authorize QoS simultaneously, and pass through according to corresponding PCC rule decision Business Stream.
Step 13, IP-CAN carries demand signalling in the GW response of step 1.
More than be in the prior art, in the PCC framework, revise the detailed process of IP-CAN session.
In GPRS network, the user inserts first and will go up the session of creating a correspondence at GGSN (PCEF is arranged in this GGSN); When if new business demand is arranged again, can upgrade the service quality of original carrying, also can initiate secondary activating once more, under original session, create a new carrying.Receive the restriction of NSAPI, can create 11 carryings under the same session at most, and each session information that carries, like SGSN address, Routing Area identification symbol (RAT, Routing Area Identifier) etc., need unanimity.Along with networks development and professional diversification, more and more users is selected to set up many carryings, satisfies its multi-service requirement.
So, the user signs in in the network, takes place to roam when carrying out inter-office switchover, will take place many to GGSN and upgrade request.Therefore, when realizing PCEF, if same session inserts a plurality of carryings down, update processing is except accomplishing the agreement flow process, and also need solve following two kinds of problems: same session level parameter is revised in a plurality of carryings simultaneously; The different sessions parameter is revised in a plurality of carryings simultaneously.
The inventor finds to have following problem at least in the prior art in realizing process of the present invention: the flow process of in the agreement session parameter being made amendment only is useful in a carrying generation session level and more carries out under the news.When the user signs in to network; The carrying that the more frequent renewal of meeting has been set up is to obtain different services; Do not have in the PCEF function under the situation of message buffering mechanism, the situation to the session level parameter update is all initiated in two or more carryings that can take place under the same session; If the inharmonious well more processing of new technological process causes it to upgrade failure, then can influence user satisfaction to a great extent.
