Abstract
The invention discloses a method and a system for charging a mobile data service. The method comprises the following steps that: when a user requests a new packet data protocol (PDP) service, a gateway GPRS (general packet radio service) support node (GGSN) triggers an on-line charging system (OCS) to charge an unbilled service flow which is generated by the user at present after determining that the PDP service is required to be charged on line according to the user request, distributes flow quota for the PDP service and notices the GGSN; and the GGSN monitors the using flow of the PDP service according to the current flow quota of each PDP service, triggers the OCS to charge the unbilled service flow which is generated by the user at present when the using flow of the PDP service reaches the flow quota, newly distributes the flow quota for the PDP service and notices the GGSN. By the method and the system, an operator is prevented from being unpaid, so the user can control consumption expenditure.
Description
Technical field
The present invention relates to the billing technology in mobile communication system, particularly relate to a kind of charging method and system of mobile data services.
Background technology
In the charging method of existing mobile data services, after the user uses the mobile data services such as GPRS, charging gateway (Charging Gateway, CG) produces this user's use recording call list, and charge system carries out to the mobile subscriber, collecting the charges after wholesale price according to this ticket again.Visible, in above-mentioned charging method, the users such as needs carry out the wholesale price charge to its ticket after the data business is finished using again.And at present, development due to technology, mobile data services are from initial GPRS to EGPRS, and the 3G technology development such as follow-up UMTS and HSPDA, greatly improved the speed of getting online without being tethered to a cable, the data traffic that the user uses has simultaneously also obtained rapid growth, easily produces high cost when this will make the each usage data business of user.Obviously, the above-mentioned charging way that the regeneration ticket carries out the wholesale price charge after data service is finished using, will cause operator immediately not charge, thereby exist by the risk of arrearage, also can there be the problem of the cost of use of uncontrollable its data service in the user simultaneously.
At present, in order to address the above problem, adopted the ticket cutting techniques in charge system.This charge system mainly comprises following part: critical point GPRS Support Node (Gateway GPRS Support Node, GGSN), charging gateway, business operation support system (Business & Operation Support System, BOSS).Ticket is cut apart and is referred in use, according to certain condition, by critical point GPRS Support Node (Gateway GPRS Support Node, GGSN) generate a minute patrilineal line of descent with only one son in each generation and deliver to charging gateway, generate interim UDR and export to BOSS after regularly dividing single the merging by charging gateway, BOSS carries out wholesale price to middle ticket and processes the rear line charge, like this, can improve to a certain extent the promptness of charge.
But, still there is following defect in the existing charging method of ticket cutting techniques that adopts: ticket is cut apart and is regularly to carry out, consider to cut apart and too frequently can have the network element system excessive problem of loading, therefore, normally within 15 minutes, generate an interim UDR, this will make ticket delay to reach BOSS, thereby cause occurring the problem of subscriber arrearage, especially in the situation that network speed is high, also will have the problem of great number arrearage, the user also can't control its consumption amount of money situation in time simultaneously.
As can be seen here, the charging method of existing employing ticket cutting techniques, still can't avoid producing operator by the problem of arrearage and uncontrollable its consumption amount of money of user.

In actual applications, described step can further include: the process that the anomalous event occurred during to described monitoring is processed.Described anomalous event comprises: the anomalous event between the anomalous event at SGSN place and OCS and GGSN.
When anomalous event that described anomalous event is the SGSN place, described GGSN is according to the situation of described user's the requested termination of PDP business, triggers described OCS and carries out corresponding described charging and process;
When described anomalous event is the anomalous event between OCS and GGSN, described OCS and described GGSN find will automatically proceed to abnormality processing flow process separately after the other side is broken down by exploration separately, and wherein, the abnormality processing flow process at described GGSN place comprises:
There is no corresponding CCR information reporting if described fault is described PDP to be connected, described GGSN connects the cancellation of corresponding CC sign by this PDP, generate minute ticket to described CG simultaneously, within described minute, in ticket, do not comprise that the last described OCS of triggering carries out the expense of charging service traffics afterwards, notifies described CG to be merged a minute ticket; Carrying out charging service traffics afterwards according to the described the last described OCS of triggering generates offline bill and sends to BOSS through described CG.
Here, being triggered to the service traffics that described OCS carries out after charging the last time is included in offline bill and is processed as follow-up offline business amount.
Be connected with corresponding CCR information reporting if described fault is described PDP, but do not receive corresponding CCA message, described GGSN connects the cancellation of corresponding CC sign by this PDP; If described CCR message is letter control request, described GGSN processes the use amount in this CCR as online use amount, and generation minute ticket is given described CG simultaneously, notifies described CG to merge, and a follow-up minute ticket is pressed the offline bill generation and processed; If described CCR message is the charging event request, described GGSN is online minute list by nonoculture in this minute, notifies described CG to merge, and follow-up minute individual palpation offline bill generates to be processed.
When OCS recover normal after, described GGSN no longer triggers described OCS the service traffics of the described user's that produces before this not wholesale price is carried out to the charging processing.
The abnormality processing flow process at described OCS place comprises:.
Described OCS discharges the expense of temporary locking, and after the use service traffics that simultaneously will also not generate ticket generate wholesale price, ticket is exported to BOSS;
If described fault is described PDP, do not have CCR to report, OCS has carried out wholesale price to the use amount of all business accumulative totals of the last letter control request since by this PDP charging event last time and generates ticket;
If being described OCS, described fault receives the CCR message of the PDP that described GGSN reports, but do not know that whether the CCA message sent to described GGS is successful, described OCS has carried out after total use amount since last charging processing merges carrying out wholesale price by the use amount that reports in this CCR message with to described user's PDP business, generates charging bill to described BOSS;
Described OCS, according to the expense in described ticket, deducts described user's account balance.
In actual applications, before described step 101, can also comprise: SGSN, according to user's PDP Context request, triggers as described user sets up PDP and connects.
Particularly, setting up the method that PDP connects can be:
Described user sends to described SGSN the PDP Context request that activates;
Described SGSN, according to the request of described activation PDP Context, sends and creates the PDP Context request message to described GGSN, carries described user's the attribute information for online generation ticket in described establishment PDP Context request message;
Described GGSN, according to the sign of the online charging in described establishment PDP Context request message, after determining the request that described request is pre-paid type, sends the CCR initial message to described OCS;
Described OCS sets up control connection according to described CCR initial message, to described GGSN, replys CCA message, carries effective duration (Validity-Time) of object code (Result-Code) and flow quota in described CCA message.
Here, described GGSN processes accordingly according to the described object code in described CCA message, and described processing comprises:
When described object code is while being used to indicate the information that needs normal monitoring, described GGSN notifies the described PDP of described SGSN to connect and is successfully established, and after this when described user uses the PDP business described GGSN need to carry out the monitoring for real time billing to described PDP business;
When described object code is while being used to indicate described user's the information of account balance deficiency, described GGSN notifies the described PDP of described SGSN to connect and sets up unsuccessfully;
When described object code is while being used to indicate the information that does not need monitoring, described GGSN notifies the described PDP of described SGSN to connect and is successfully established, and after this when described user uses the PDP business without described PDP business is carried out to the monitoring for real time billing.
In actual applications, set up described PDP connection and can also comprise the set-up procedure of setting up described PDP connection before, described set-up procedure comprises:
It is the targeted customer that described BOSS establishes described user, and described user's attribute information is sent to described OCS, and described attribute information comprises essential information and the accounts information of described user's usage data business; When the attribute information according to described user is determined while need to carry out real time billing to described user, to be loaded into attaching position register (HLR) for the online attribute information that generates ticket, described online charging sign (CC) and the speech business online charging CAMEL-Subscription-Information that comprises described user for the online attribute information that generates ticket; When meeting default attribute and issue condition, described HLR is handed down to described SGSN by described for the online attribute information that generates ticket, described attribute issues condition and comprises: when the described attribute information that described user preserves in attachment state and described HLR changes, or when described user transfers the described SGSN of PMM-Connected state to described HLR inquiring user attribute to by the PMM-Detached state.
After step 102, can also comprise: when the requested termination of described user's PDP business, described GGSN triggers described OCS the service traffics of the not wholesale price of the current generation of described user is carried out to the charging processing.
Concrete, described OCS completes after described charging is processed and sends CCA message to described GGSN, described GGSN is that the service traffics that described OCS carries out described charging processing for the last time generate minute ticket carry described online charging sign, described minute ticket sent to described CG, described CG will receive described minute ticket and be incorporated in the described user's who self preserves ticket, described BOSS gathers the described user's of described CG preservation ticket according to default bill record collection strategy, according to the online charging in described ticket, identify, the described user's of online charging ticket is added up.
In technique scheme, can find out, the present invention first went out current spendable flow quota according to user's account balance before the permission user, using the PDP business for the user is pre-configured, make the user carry out the use of PDP business in this flow quota limited range, according to first carrying out withholding fee, and then the mode of authorized user use, the PDP service traffics of guaranteeing the user can not exceed its account balance limited range, thereby can effectively avoid operator by arrearage, by OCS, the campus network of the current generation of user is notified immediately to the user simultaneously, the expense that so just can make the user produce its PDP service traffics is controlled.Below by a pair of above-mentioned charging method of the embodiment of the inventive method and system, be described further.
Fig. 2 is the system configuration schematic diagram in the embodiment of the present invention one, and this system mainly comprises as shown in Figure 2:
BOSS, for preserving customer service data and balance amount information, be confirmed whether to carry out real time billing to it according to user property and traffic performance thereof, if need its GPRS online charging sign and speech business online charging CAMEL-Subscription-Information are loaded in HLR;
Described HLR, used the base attribute of network for preserving the user, after the load information of receiving described BOSS, described CC sign is passed to SGSN;
Described SGSN, for connecting base station/radio network controller (BSC/RNC) and GGSN, receive the information from described HLR, the user, when initiating the PDP request, described CC sign passed to GGSN;
Described GGSN, for Service control, the PDP that SGSN is passed over is resolved, and is forwarded to different gateways, according to the sign of the CC in PDP, this PDP is triggered to OCS, for online charging PDP, the user, uses increase CC sign in ticket to pass to CG;
Described CG, for generation of the ultimatum list, to the ticket increase CC sign of online charging, ticket passes to described BOSS after generating;
OCS, be used for and BOSS sharing users data and balance amount information, receive the authentication request that described GGSN sends simultaneously, according to the user, current account balance and the flat allocation quota flow inverse of PDP business go out the current spendable flow quota of corresponding PDP business, authorize GGSN to control the user and use described PDP business, the user, use in described PDP business procedure, pin the remaining sum of corresponding service authorization part according to described flow quota, control user multi-service uses simultaneously, after the user finishes described PDP business, the ticket generated immediately after wholesale price sends to BOSS to inquire about for the user.
According to the packet domain characteristics, there is the situation of single business or a plurality of business in a PDP, and for keeping consistency, the present embodiment is all undertaken by multi-service mode, and in actual applications, single business can be used as multiple services special circumstances.Overall flow is divided into PDP activation, service monitoring, three kinds of normal flow of PDP deexcitation, and abnormal flow processing.
One, activation process
(1) preparation
1, BOSS dynamically generates the targeted customer, and user, Account Profile are passed to OCS;
2, BOSS is loaded into targeted customer's charging property CC in HLR.
(2), attribute issues: HLR is to SGSN (take 3G subscription as example)
State according to 3G subscription in SGSN is divided into three kinds of situations:
1, PMM-Detached: released state, HLR information can not be handed down to SGSN;
2, PMM-Idle: adhere to but, without the signaling connection status on the Iu interface, the HLR attribute change will be inserted in SGSN;
3, PMM-Connected: adhere to and the signaling connection status on the Iu interface is arranged, the HLR attribute change will be inserted in SGSN;
4, when the user initiates PS Attach request, User Status transfers PMM-Connected to by PMM-Detached, and SGSN is to HLR inquiring user attribute, and HLR inserts user profile in SGSN by ISD message.
(3), activation process
1, the user initiates " Active PDP Context Request " request.
2, SGSN initiates " Create PDP Context Request ", by IMSI, and MSISDN, CC, APN, SGSN-IP, the information exchanges such as RAT are crossed gn interface and are sent GGSN to.
3, GGSN analyzes the request that CC is designated pre-payment (Prepaid) type, to OCS, initiates CCR (Initial) message, and request OCS sets up control connection.
OCS replys CCA message, wherein carries Result-Code, and effective duration Validity-Time of quota.
GGSN returns results according to OCS, carries out different disposal:
1) if OCS returns results code need normally be monitored for " 2001 ", GGSN notice SGSN " PDP Context " is successfully established, and subsequent user while using business GGSN need report OCS to be monitored;
2) if return results code when " 4012 " Sorry, your ticket has not enough value (user is abnormal), " PDPContext " activates unsuccessfully;
3) if return results code for " 4011 " without monitoring, normally set up PDP, and the follow-up business of this PDP is also without reporting OCS to be monitored.
Two, monitoring flow process
After PDP is successfully established, enter the business monitoring flow process, can monitor a plurality of business simultaneously, a plurality of business are carried out to real time billing.Following flow process is initiated the flow process of 2 service request for the user.
User's initiating business request, GGSN matches the business 1 of this PDP, and checks at present without OCS mandate quota;
GGSN initiates CCR (Update) message, wherein contains the sign of business 1;
OCS wholesale price, deduct fees (if flow is arranged, and recording), calculated flow rate quota withholding fee;
OCS replys CCA (Update) message, allocated quotas, and time timer and the quota threshold values of notice GGSN business 1;
The GGSN authorized user is used business 1;
The user initiates new service request, and GGSN matches business 2, and authorizes quota without OCS at present;
GGSN initiates CCR (Update) message, wherein contains the sign of business 2;
OCS wholesale price, deduct fees (if flow is arranged, and recording), calculated flow rate quota withholding fee;
OCS replys CCA (Update) message, allocated quotas, and time timer and the quota threshold values of notice GGSN business 2;
The GGSN authorized user is used business 2;
Business 1 use traffic reaches the quota threshold values;
GGSN initiates CCR (Update), the traffic carrying capacity that reporting service 1 has been used, and reporting reason is that use traffic reaches the quota threshold values;
OCS wholesale price, deduct fees (use amount reported is accumulated and gathered and again deduct fees), recalculate flow quota withholding fee; ;
OCS replys CCA (Update) message, again assigns quota to business 1; GGSN continues to allow the user use business; Last time, remaining quota lost efficacy;
The timer of business 2 arrives;
GGSN initiates CCR (Update), the traffic carrying capacity that reporting service 2 has been used, and reporting reason is to arrive the time timer time;
OCS wholesale price, deduct fees (use amount reported is accumulated and gathered and again deduct fees), recalculate flow quota withholding fee;
OCS replys CCA (Update) message, redistributes quota to business 2; GGSN continues to allow the user use business; Last time, remaining quota lost efficacy; If the user is now without expense, in replying CCA (Update) message, request notifies the GGSN interrupting service 2 (and being redirected to the tips page face).
Business 1 can continue to use.
Three, deexcitation flow process
GGSN initiates CCR (TERMINATE) and reports PDP to finish, and all business use amounts of this PDP (use amount since reporting last time from each business) has been reported to OCS simultaneously;
The OCS wholesale price, deduct fees and reply CCA (TERMINATE);
OCS generates ticket after wholesale price by this PDP, and sends BOSS to.
GGSN sends the ticket (finally dividing of this PDP is single) identified containing CC, and, to CG, dividing that CG will identify containing CC singly be merged into the ticket containing CC, spanned file;
BOSS gathers the CG ticket, according to field CC sign, will be done statistical disposition by the ticket of normal real time billing.
Charging flow
Charging event refers in the Mobile data Real-time Billing System need OCS to produce the event of charging bill, its trigger condition comprises the time-switching that SGSN upgrades, OCS initiates (rate switching, change day switching), OCS cuts apart event, PDP deexcitation to overlength PDP, and the charging event that causes of abnormal flow process.(annotate: the PDP deexcitation is a kind of as charging event)
Its main flow process:
GGSN sends to the CC in list that divides of CG to be designated real time billing under the PDP monitor state.
OCS issues (by CCA, issuing Tariff--Time-Change) to GGSN according to the time-switching rule, requires GGSN to report this charging event according to the time (absolute time) of " time-switching charging " event definition in CCA.Wherein to overlength PDP (more than 30 minutes) OCS, by the rate switching mode, notify GGSN, report when the time comes charging event, solve the problem that the long user of PDP can not inquire about ticket in time.
CG merges respectively according to the CC sign, and the ticket of monitoring and do not monitor is merged respectively.
Charging event: refer to the time-switching that SGSN upgrades, GGSN initiates (containing OCS, requiring to report part), PDP deexcitation.
1), charging event while producing GGSN generate minute singly to CG, and require CG to carry out the ticket merging;
2), be triggered to OCS by CCR simultaneously; Comprising triggering reason (SGSN renewal, rate switching etc.).
3), after OCS receives such CCR, judgement triggers reason, in this PDP, the preallocated quota of each business (expense) all discharges at present;
A) OCS by this PDP charging event last time since each business use amount gathered, generate the wholesale price ticket, expense in ticket is deducted from the OCS remaining sum;
B) ticket is passed to BOSS simultaneously the user is provided.If this PDP of OCS did not generate ticket, this ticket sequence number is 1, otherwise the ticket sequence number increases progressively.
C) for a plurality of business are arranged in a PDP, by 6 one group of business, generate a ticket, the ticket sequence number increases progressively.
D) after ticket generates, to this PDP, the use amount accumulated value of each current business carries out initialization.
4) in the CCA that OCS replys, need each business in this PDP is authorized again.GGSN is monitored each business according to new quota.
The ticket that BOSS transmits according to OCS provides the user; According to CC sign in G_CDR, as the statistics ticket, process.
Abnormal flow process
In the Mobile data Real-time Billing System, SGSN, GGSN, Gy, OCS all may exist extremely, and when abnormal generation, total principle is to keep user PDP to use not interrupt as far as possible, and during interruption, GGSN reports the use traffic carrying capacity of OCS as the traffic carrying capacity of having deducted fees online.After interrupting recovering, original PDP is no longer monitored, and PDP when GGSN is to interruption no longer is triggered to OCS after system is recovered.
(1) SGSN is abnormal:
As PDP, deexcitation reports to OCS GGSN, by deexcitation, processes.
(2) abnormal between OCS and GGSN:
