Fig. 2 is the disclosed billing control method flow chart of the embodiment of the invention; As shown in Figure 2; The user creates first session; PCEF sends the time started information and the user totem information of first session to PCRF; After PCRF received the time started information and user totem information of first session, indication PCEF report of user was visited the actual time started information of non-specified services, and issued the duration based accounting strategy of first session to PCEF; PCEF is connected with the charging that OCS sets up first session according to the duration based accounting strategy that issues, and applies for the used duration of first session; After PCEF started the session duration based accounting, whether monitoring users first session stopped, if first session stops; Then send the first conversation end temporal information to PCRF, PCRF preserves the first conversation end temporal information, also judges whether also exist other movable sessions (as; Second session); If also there is second session in the user, then PCRF is with in first session duration based accounting policy distribution to the second session, and the charging that second session continues to use first session to set up connects; If there is not second session in the user, then PCRF issues the chargeable session termination message based on the first conversation end temporal information, and PCEF stops being connected with the session charging of OCS according to the chargeable session termination message, realizes that billing control method needs following steps, specifically comprises:

Step 210, set up first session, the time started information and the user totem information of said first session sent to strategy and charging regulation function entity PCRF;

Particularly, the user sends a PDP context activating request information to GPRS serving GPRS support node (Serving GPRS Support Note SGSN), comprises APN information in solicited message; After SGSN passes through the user capture authentication, promptly to user identity identification, data encryption and compression step; Obtain the address information of the GGSN of service based on APN, (Gateway GPRS SupportNode GGSN) sends and creates the PDP Context solicited message to Gateway GPRS Support Node; GGSN distributes to IP address information; And accomplish PDP activation, the passage that connects between while and the SGSN is in GPRS network; GGSN is the concrete entity of PCEF, also can be the billing gateway device between GGSN and the data field; The user is through the IP address allocated access data network; Like browsing page, reception/transmission multimedia message, access internet etc.; The user is known as a session, when conversation establishing through the IP address allocated access data network time; PCEF sends original request message to PCRF, in original request message, includes the time started information and the user totem information of first session.

Step 220, according to the duration based accounting strategy that said PCRF issues, set up session charging with Online Charging System OCS and be connected; Connect through said session charging, utilize said duration based accounting strategy that said first session is chargeed;

After PCRF receives the first session time started information and user totem information of PCEF transmission; Whether according to identification information judgment is user's the session first time, if then PCRF is provided with to start duration based accounting when whether the user visits non-specified services; If not, then be not provided with; Here, just start duration based accounting when visiting non-specified services through being provided with, whether indication PCEF starts duration based accounting or when starts duration based accounting, and only when the non-specified services of visit, PCEF just starts duration based accounting to the user, makes the use of PCEF more flexible.

If start the duration based accounting function when PCRF is provided with the non-specified services of user capture; Then issue and reserve the duration based accounting strategy to PCEF; PCEF is according to the content of reserving in the duration based accounting strategy; Monitoring users is visited the time of non-specified services, the actual time started information of the non-specified services of user capture that reports according to PCEF, and PCRF issues the duration based accounting strategy.

If start the duration based accounting function when PCRF is provided with the user capture specified services; Then PCRF judges that voluntarily whether first session need start duration based accounting, if first session need start the duration based accounting strategy, then issues the duration based accounting strategy to PCEF; Otherwise, do not issue the duration based accounting strategy.

PCEF is connected with the charging that OCS sets up first session based on the duration based accounting strategy that issues; Connect through first session charging, utilize the duration based accounting strategy that first session is chargeed;

After the charging that PCEF and OCS set up first session was connected, the application information of sending the used duration of first session to OCS obtained the used duration of first session.

Step 230, set up second session, the time started information and the user totem information of said second session sent to said PCRF;

Particularly, the user sets up second session, and the time started information and the user totem information of second session sent to PCRF;

Need to prove that can there be a plurality of session activations simultaneously in a user, like second session; The 3rd session etc., during each conversation establishing, PCEF all can send the time started information and the user totem information of this session to PCRF; PCEF also monitors each session simultaneously, and PCRF stores the time started information and the user totem information of this session, is used for behind previous conversation end; Judge whether also to exist other active session; Promptly behind previous conversation end, the time started information and the user totem information of other sessions of storage before PCRF calls utilize the time started information and the user totem information of other sessions of storage to judge whether other sessions also existed in the moment when previous conversation end; If PCRF judges other sessions and exists; The duration based accounting strategy migration that then will work as in the previous session is issued in other sessions, otherwise, do not issue the duration based accounting strategy.

Step 240, when said first session stops, notify said PCRF the said first session termination message;

Particularly, PCEF monitors first session after starting duration based accounting, based on whether also existing business data flow to judge whether first session finishes in first session, if PCEF judges first conversation end, then reports the first conversation end temporal information to PCRF; If PCEF judges that first session does not finish, then continue to monitor first session and use duration.

The indication of step 250, the said PCRF of reception, said indication comprise that said second session continues to use the duration based accounting strategy in said first session.

Particularly; PCRF, upgrades user's duration accumulative total service recorder and preserves after the first session termination time information that step 240 is sent based on PCEF, utilizes the time started information of each session that PCEF sends and the session activation whether the user totem information judges also exists other; If there is not other session in the user; PCRF promptly includes Stop information in the indication information of the chargeable session between termination and OCS, then expression needs end chargeable session to the indication information that PCEF issues the chargeable session between termination and OCS; After PCEF receives this information, the chargeable session between termination and OCS.

When if still there are other sessions in the user, like second session, PCRF issues the indication information of the chargeable session between termination and OCS to PCEF; Promptly include Reserved information in the indication information of the chargeable session between termination and OCS, represent that then also there is second session in the user, need to continue chargeable session; After PCEF receives this information; Continue the chargeable session between maintenance and OCS, PCRF is with in the session of duration based accounting policy distribution to the second, and the charging that second session continues to use first session to set up connects.Certainly, said PCEF also can set up new the charging for second session and connect, and the new charging of setting up through said second session connects, and utilizes the duration based accounting strategy in said first session that said second session is chargeed.

Need to prove; The described method of preceding text is the practical implementation process that example describes billing control method with single user memory in many sessions; In practical application, multi-user conversation promptly also can be accomplished session charging according to aforesaid billing control method by the conversation group that a plurality of users make up.

Particularly; After first user creates session; PCEF sends time started information and user's group identity information of first user conversation to PCRF; After PCRF received the first session time started information and user's group identity information, indication PCEF reported the actual time started information of the non-specified services of first user capture, and issued the duration based accounting strategy of first user conversation to PCEF; PCEF is connected with the charging that OCS sets up first user conversation according to the duration based accounting strategy that issues, and applies for the used duration of first user conversation; After PCEF starts the session duration based accounting; Whether monitor first user conversation stops; If first user conversation stops, then send the first user conversation concluding time information to PCRF, PCRF preserves the first user conversation concluding time information; Judge whether also to exist the session (like, second user conversation) of other User Activities;

Need to prove, can have a plurality of users' session during a user organizes simultaneously, like second user conversation; The 3rd user conversation etc.; When each user created session, PCEF all can send time started information and user's group identity information of this user conversation to PCRF, and PCRF stores time started information and user's group identity information of this user conversation; Be used for after finishing, judging whether also to exist other movable user conversations when previous user conversation;

Because the user is when creating session; PCEF all can send time started information and user's group identity information of this user conversation to PCRF, and therefore, PCRF judges whether the user's group identity information that receives is the identification information of same user's group; If the identification information of same user's group; Then store time started information and user's group identity information of this user conversation, otherwise, do not store;

If also there is second user conversation, then PCRF is with in first user conversation duration based accounting policy distribution to the second user conversation, and the charging that second user conversation continues to use first user conversation to set up connects; Certainly, said PCEF also can set up new the charging for second session and connect, and the new charging of setting up through said second session connects, and utilizes the duration based accounting strategy in said first session that said second session is chargeed.

If there is not second user conversation, then PCRF issues the chargeable session termination message based on the first user conversation concluding time information, and PCEF stops being connected with the session charging of OCS according to the chargeable session termination message.

Through description to said method; Issue the duration based accounting strategy by PCRF; PCEF carries out the duration based accounting strategy and sets up charging with OCS and is connected; Realize that list is shared with indoor many sessions duration, under standard card cage, can support data service more flexibly, be easy to realize single efficient, accurate billing control with indoor many sessions duration.Similarly, can realize that also the charging duration of same user being organized interior user merges.
