Embodiment

For making the technical scheme of the embodiment of the present invention and the clearer of advantage expression, below by drawings and Examples, the technical scheme of the present invention is described in further detail.

Fig. 2 is a billing control method schema disclosed in the embodiment of the present invention; As shown in Figure 2, user creates the first session, PCEF sends time opening information and the user totem information of the first session to PCRF, after the time opening information that PCRF receives the first session and user totem information, instruction PCEF report of user accesses the actual time opening information of non-designated business, and issues the time long charging strategy of the first session to PCEF; The charging that PCEF sets up the first session according to the time long charging strategy issued with OCS is connected, and applies for the used time length of the first session; When PCEF starts session after long charging, whether monitoring users first session terminates, if the first session terminates, then send the first conversation end time information to PCRF, PCRF by first the conversation end time information preserve, also judge user whether also exist other activities session (as, 2nd session), if user also exists the 2nd session, then PCRF is by charging policy distribution long during the first session in the 2nd session, and the 2nd session continues to use the charging of the first session establishment to connect; If user does not exist the 2nd session, then PCRF issues chargeable session termination message based on the first conversation end time information, and PCEF terminates being connected with the session charging of OCS according to chargeable session termination message, it is achieved billing control method needs following step, specifically comprises:

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

Specifically, user sends one and activates PDP context request information to GPRS service support node (ServingGPRSSupportNote, SGSN), comprises APN information in request information; After user's access authentication is passed through by SGSN, namely to user identity identification, data encryption and compression step, the address information of the GGSN of service is obtained based on APN, node (GatewayGPRSSupportNode is supported to gateway GPRS, GGSN) establishment PDP context request information is sent, GGSN distributes to User IP address information, and complete PDP activation process, simultaneously and the passage that connects between SGSN, in the gprs networks, GGSN is the concrete entity of PCEF, it is also possible to be the billing gateway device between GGSN and data field; User is by the IP address access data network of distribution, as browsed webpage, reception/transmission multimedia message, access internet etc., user is when the IP address access data network by distributing, it is referred to as a session, when conversation establishing, PCEF sends original request message to PCRF, includes time opening information and the user totem information of the first session in original request message.

Step 220, the time long charging strategy issued according to described PCRF, set up session charging with online charge system OCS and be connected; Being connected by described session charging, when utilizing described, described first session is carried out charging by long charging strategy;

PCRF receive PCEF send the first session start time information and user totem information after, according to the first time session whether identification information judgment is user, if it does, then PCRF arranges starting duration charging when whether user accesses non-designated business, if, then do not arranged; Here, just starting duration charging during by arranging access non-designated business, whether instruction PCEF starting duration charging or when starting duration charging, and user is only when accessing non-designated business, and PCEF just starting duration charging, makes the use of PCEF more flexible.

If PCRF arranges starting duration billing function when user accesses non-designated business, long charging strategy when then issuing reserved to PCEF, PCEF is according to the content in long charging strategy time reserved, monitoring users accesses the time of non-designated business, the user reported according to PCEF accesses the actual time opening information of non-designated business, long charging strategy when PCRF issues.

If PCRF arranges starting duration billing function when user accesses specified services, then PCRF judges that the first session is the need of starting duration charging voluntarily, if the first session needs starting duration charging strategy, then and long charging strategy when issuing to PCEF, otherwise, long charging strategy when not issuing.

The charging that PCEF sets up the first session based on the time long charging strategy issued with OCS is connected; Being connected by the first session charging, when utilizing, the first session is carried out charging by long charging strategy;

PCEF and OCS set up the first session charging connect after, to OCS send the first session used time length application information, obtain the used time length of the first session.

Step 230, set up the 2nd session, the time opening information of described 2nd session and user totem information are sent to described PCRF;

Specifically, user sets up the 2nd session, and the time opening information of the 2nd session and user totem information are sent to PCRF;

It should be noted that, can there is multiple session activity in a user simultaneously, such as the 2nd session, 3rd session etc., during each conversation establishing, PCEF all can send time opening information and the user totem information of this session to PCRF, PCEF also monitors each session simultaneously, the time opening information of this session and user totem information are stored by PCRF, for after a current conversation end, judge whether also there is other active session, namely after a current conversation end, the time opening information of other sessions that PCRF stores before calling and user totem information, time opening information and the user totem information of other sessions stored is utilized to judge other sessions are whether the moment of a current conversation end also exists, if PCRF judges that other sessions exist, then the time long charging policy migration in a current session is issued in other sessions, otherwise, long charging strategy when not issuing.

Step 240, when described first session terminate time, notify the first session termination message described in described PCRF;

Specifically, after PCEF starting duration charging, monitor the first session, judge whether the first session terminates based on whether the first session also exists business data flow, if PCEF judges the first conversation end, then report the first conversation end time information to PCRF;If PCEF judges that the first session does not terminate, then continue to monitor when the first session uses long.

Step 250, the instruction receiving described PCRF, described instruction comprises described 2nd session and continues to use the time long charging strategy in described first session.

Specifically, after the first session termination time information that PCRF Based PC EF sends in step 240, when upgrading user, accumulative use of length records and preserves, time opening information and the user totem information of each session that PCEF sends is utilized to judge whether user also exists other session activity, if there is not other session in user, PCRF issues the indication information of the chargeable session between termination and OCS to PCEF, namely terminate and OCS between chargeable session indication information in include Stop information, then represent and need to terminate chargeable session, after PCEF receives this information, chargeable session between termination and OCS.

If when still there are other sessions in user, such as the 2nd session, PCRF issues the indication information of the chargeable session between termination and OCS to PCEF, namely terminate and OCS between chargeable session indication information in include Reserved information, then represent user also there is the 2nd session, it is necessary to continue chargeable session, after PCEF receives this information, continue to keep and chargeable session between OCS, PCRF will time long charging policy distribution in the 2nd session, the 2nd session continues to use the charging of the first session establishment to connect. Certainly, described PCEF can also be that the 2nd new charging of session establishment connects, and is connected by the new charging of described 2nd session establishment, utilizes the time long charging strategy in described first session that described 2nd session is carried out charging.

It should be noted that, the specific implementation process that many sessions are described billing control method is there is in method as described above in single user, in actual applications, multi-user conversation, the conversation group namely built by multiple user also can complete session charging according to aforesaid billing control method.

Specifically, after first user creates session, PCEF organizes identification information to time opening information and the user of PCRF transmission first user session, PCRF receives the first session start time information and after user organizes identification information, instruction PCEF reports first user to access the actual time opening information of non-designated business, and issues the time long charging strategy of first user session to PCEF; The charging that PCEF sets up first user session according to the time long charging strategy issued with OCS is connected, and applies for the used time length of first user session; When PCEF starts session after long charging, monitor whether first user session terminates, if first user session terminates, then send first user conversation end time information to PCRF, first user conversation end time information is preserved by PCRF, e.g., judge whether also to exist the session (the 2nd user's session) of other User Activities;

It should be noted that, user's group can exist the session of multiple user simultaneously, such as the 2nd user's session, 3rd user's session etc., when each user creates session, PCEF all can send the time opening information of this user's session to PCRF and user organizes identification information, and the time opening information of this user's session and user are organized identification information storage by PCRF, for, after current user's conversation end, judging whether also to exist user's session of other activities;

Owing to user is when creating session, PCEF all can send the time opening information of this user's session to PCRF and user organizes identification information, therefore, PCRF judges that the user received organizes whether identification information is the identification information that same user organizes, if the identification information of same user group, the time opening information and the user that then store this user's session organize identification information, otherwise, do not store;

If also there is the 2nd user's session, then PCRF is by charging policy distribution long during first user session in the 2nd user's session, and the 2nd user's session continues to use the charging of first user session establishment to connect; Certainly, described PCEF can also be that the 2nd new charging of session establishment connects, and is connected by the new charging of described 2nd session establishment, utilizes the time long charging strategy in described first session that described 2nd session is carried out charging.

If there is not the 2nd user's session, then PCRF issues chargeable session termination message based on first user conversation end time information, and PCEF terminates being connected with the session charging of OCS according to chargeable session termination message.

By the description to aforesaid method, long charging strategy when issuing by PCRF, long charging strategy when PCEF performs also is set up charging with OCS and is connected, when realizing many sessions in single user, length is shared, data service more flexibly can be supported, charging efficient, the accurate control of length when being easy to realize many sessions in single user under standard card cage.
