Description

Credit control client terminal, credit control server, charge system and charging method
Technical field
The present invention relates to the billing technology in the communications field, especially provide in the process of service, credit control client terminal, credit control server, charge system and charging method that the service that provides is chargeed to terminal.
Background technology
Fast development along with data service, the respective services that the user can use operator to provide by terminal, for example: the user can use speech business by terminal, and transmitting-receiving text message, multimedia message, E-mail download CRBT and picture, shopping etc. by terminal login internet.Before this, when the user uses the respective services that the service provider provides by terminal, operator mainly adopts the back charging way that the service that the user uses is chargeed and deducted fees, that is: the remaining sum on the inquiry terminal user account not, after the user successfully uses service, calculate the expense that the user uses service again, and deduct the expense that calculates from user account.The defective that this back charging way exists is: may have that Sorry, your ticket has not enough value on the terminal use account and arrearage, even the user's malicious overdraft that has uses service, this just brings great loss to operator.
At present, in the reimbursement of expense mode of various wired and wireless communications, can allow the terminal use inquire about remaining sum on the own account in real time, easily, can allow operator avoid advantages such as user's malicious overdraft account balance and arrearage owing to possess, the pre-payment means of payment has obtained a kind of reimbursement of expense mode that user and operator generally adopt at present, and will obtain using more widely.
Two kinds of pre-payment means of payment that exist have two kinds at present: a kind of is the mode of keeping accounts immediately, and another kind is to reserve charging way.
Book keeping operation mode immediately is when credit control client terminal receives the service request of terminal transmission, sends book keeping operation request immediately to credit control server; Credit control server charges and deducts fees the service of terminal request after receiving book keeping operation request immediately; After successfully deducting fees, send book keeping operation request immediately to credit control client terminal and reply; After the credit control client terminal book keeping operation request immediately of receiving is replied, provide service to terminal.This method requires credit control server to deduct fees after the success, guarantees that credit control client terminal one successfully provides its requested service to terminal surely.And in a single day meet accident, for example: any one problem appears in terminal, credit control client terminal, credit control server or its employed communication network, all can't satisfy this condition, and this has just damaged user's economic interests, and makes troubles to the user; In addition,, need loaded down with trivial details matters such as process user so the complaint that causes, claim, the verification fact, certainly will expend great amount of manpower and material resources, bring very big inconvenience to operator equally for operator.Therefore, at present, operator has avoided using this charging way as far as possible.
Reserving charging way is present most popular a kind of charging method, as shown in Figure 1, is that prior art is reserved the flow chart that charges, and its specific implementation flow process is: terminal is initiated service request (steps A) to credit control client terminal; When credit control client terminal receives the service request of terminal transmission, send the beginning conversation request to credit control server, this begins to carry in the conversation request terminal user identification and request reservation amount (step B); After credit control server is received the beginning conversation request, on terminal use's account, reserve with request and reserve the corresponding reservation amount of money of amount, if it is exactly amount of money unit that amount itself is reserved in this request, then directly reserve this reservation amount of money, if it is non-amount of money unit that amount is reserved in this request, then credit control server calculates according to rate, obtains and asks to reserve the corresponding reservation amount of money of amount, and reserve this reservation amount of money (step C); After reserving successfully, credit control server sends the beginning conversation request to credit control client terminal and replys, and this begins to carry the approval credit rating in the conversation request answer, that is: with amount of money corresponding time length or the flow (step D) reserved; After credit control client terminal receives that sending the beginning conversation request replys, check whether the approval credit rating is zero (step e); If then refusing provides service to terminal, process ends (step N); If not, then provide service, and whether monitor terminal finishes to use service and approval credit rating whether to use up (step F) to terminal; Judge that terminal finishes service and uses up in two incidents with the approval credit rating, whether ratify credit rating and use up formerly (step G); If, then credit control client terminal sends intermediate conversational request to credit control server, request continues to use this to serve, and carries terminal user identification, the actual request reservation amount (step H) of using amount and request to reserve again of terminal in this intermediate conversational request; After credit control server is received intermediate conversational request, the reservation amount of money of once on this terminal use's account, reserving before dischargeing, and do book keeping operation and handle, the required amount payable of account's deduction this terminal actual use amount from the terminal use, if actual use amount itself is exactly an amount of money unit, then direct amount deducted, if actual use amount is non-amount of money unit, then calculate according to rate, obtain and the actual corresponding amount payable of amount of using, deduct again, and then on terminal use's account, reserve with request and reserve the corresponding reservation amount of money (step I) of amount; After reserving successfully, credit control server sends intermediate conversational request to credit control client terminal and replys, and carries terminal user identification and approval credit rating (step J) during this intermediate conversational request is replied; After this repeating step E finishes to use requested service to the flow process of step J up to terminal; If terminal finishes to use service, credit control client terminal sends end session request to credit control server, carries terminal user identification and the actual amount (step K) of using in this end session request; After credit control server receives the end session request of credit control client terminal transmission, the reservation amount of money of once on this terminal use's account, reserving before dischargeing, and do book keeping operation and handle, the required amount payable of account's deduction this terminal actual use amount from the terminal use, if actual use amount itself is exactly an amount of money unit, then direct amount deducted, if actual use amount is non-amount of money unit, then calculate according to rate, obtain and the actual corresponding amount payable of amount of using, deduct (step L) again; Send end session request to credit control client terminal then and reply (step M).
By above-mentioned flow process as can be known, reserve charging way and have following characteristics:
1, the service procedure complexity.In order to realize the charging demand to service, generally speaking, each service all needs credit control client terminal to send a beginning conversation request, repeatedly intermediate conversational request and an end session request to credit control; And credit control client terminal and credit control server all need to preserve service state.
2, information interaction is frequent.Because reserve and deduct fees and to be consistent, under many circumstances, for example: if sub-district switching, rate switching, particular point in time etc. take place in the process of using service terminal, also can initiate intermediate conversational request once more under the situation of reserving amount of money abundance, the condition of concrete trigger request is consulted to finish by credit control server and credit control client terminal in real time;
3, workload is big.For credit control client terminal, need monitor the request trigger condition that credit control server issues, for example: the amount monitoring always; For credit control server, need reserve certain amount of money from terminal use's account, when deducting fees, also need to discharge the amount of money of reservation.
Because These characteristics, make that reserving charging way exists tangible weak point: information interaction is frequent, has just increased the amount of information of Network Transmission, and this has just increased network burden, may cause network congestion; Workload is big, the extensive work time and the disposal ability of credit control client terminal and credit control server have been taken, influenced its service behaviour, reduced its operating efficiency, even when heavy traffic, can can't handle other-end user's normal service request, operator and terminal use are all made troubles.

Again referring to Fig. 2, credit control server can also comprise Freight Basis memory module 18, be connected with authentication module 13, be used to store default tariff information, in addition, service type information that can also stores service and as the correspondence relationship information between the remaining sum numerical value of the standard of account balance abundance, this standard can be determined according to the required rate of COS.Different COS is set the standard difference of account balance abundance, help asking the type of the service used to determine the charging way that employing is suitable according to the user.
Figure 3 shows that the structural representation of credit control client terminal embodiment of the present invention, it comprises session processing module 21, the monitoring identification module 22 and monitoring module 23 that connects successively, and the service providing module 24 that is connected with monitoring identification module 22 and monitoring module 23, monitoring module 23 also is connected with session processing module 21.Wherein, session processing module 21 is used for sending conversation request to credit control server, this conversation request can be beginning conversation request, intermediate conversational request or an end session request, and the conversation request answer that receives the credit control server feedback, it can be that the beginning conversation request is replied, intermediate conversational request is replied or the end session request answer that this conversation request is replied; Whether monitoring identification module 22 is used to check whether terminal use's account balance is sufficient, need use in the process of service in terminal, the amount of its use is limited, and whether the approval credit rating that conversation request is carried in replying is zero; Service providing module 24 is used for the indication according to monitoring identification module 22, provides service to terminal; Monitoring module 23 is used for the indication according to monitoring identification module 22, provide when service in service providing module 24 to terminal, to the actual use of terminal amount, perhaps further whether the approval credit rating is used up and monitor, and when using up, the approval credit rating used up and the actual notification message that uses amount of terminal to session processing module 21 transmission approval credit ratings, perhaps when terminal finishes to use service, send the notification message that terminal finishes to use service and the actual use of terminal amount to session processing module 21.
Figure 4 shows that the structural representation of charge system embodiment of the present invention, this charge system comprises credit control client terminal 2 and credit control server 1.Wherein, credit control client terminal 2 adopts embodiment shown in Figure 3; Credit control server 1 adopts embodiment shown in Figure 2, and pretreatment module 11 wherein communicates to connect with the session processing module 21 in the credit control client terminal 2.Wherein, the Freight Basis memory module 18 in the credit control server 1 can be omitted.
Figure 5 shows that the basic flow sheet of charging method embodiment of the present invention, it may further comprise the steps:
Obtain the terminal user identification (step 11) of carrying in the beginning conversation request that receives; Judge that whether sufficient (step 12) is then to adopt the back charging way to the service of the terminal request (step 13) of chargeing for remaining sum on the account corresponding with user ID (for example: telephone number, SIP URI); Otherwise, adopt to reserve charging way to the service of the terminal request (step 14) of chargeing.
By judging whether account balance is sufficient, the service of selecting to adopt back charging way or reservation charging way that terminal is used is chargeed, and like this, under the situation of account balance abundance, has simplified service procedure; Reduced unnecessary intermediate conversational request, reduced the information interaction between credit control client terminal and the credit control server, thereby reduced the workload of Network Transmission burden and credit control client terminal and credit control server, its service behaviour and operating efficiency have been improved, guarantee the normal process of service request, made things convenient for operator and user; Avoided also that Sorry, your ticket has not enough value on the terminal use account and arrearage even malicious overdraft use service, and operator has been brought loss.
In the charging method shown in Figure 5, judge whether abundance specifically can be for remaining sum on the account corresponding with user ID: judge with the corresponding account of described user ID on remaining sum whether greater than the numerical value of predesignating.These data can use the historical data of the required rate of service to add up, determine according to all users by operator, also can be pre-determined according to other standards by operator.Credit control server can be the independent numerical value of setting as the sufficient standard of account balance of certain user, also can be for the user of certain type set numerical value as the sufficient standard of account balance, can also set numerical value at the user's of certain user or certain type concrete COS as the sufficient standard of account balance.
If the standard of the remaining sum abundance on the account is relevant with user type and/or COS, judge that then remaining sum on the account corresponding with user ID whether during abundance, need inquire about according to user type and/or COS.Based on this, can also carry the user type and/or the service type information of request service in the above-mentioned beginning conversation request; Accordingly, in the step 11, can also obtain the user type and/or the service type information of carrying in the beginning conversation request; In the step 12, whether abundance is specially to judge remaining sum on the account corresponding with user ID: judge on this account remaining sum whether greater than predesignate corresponding to user and type/or the numerical value of COS.
Dissimilar users or serve employed rate may be different, determine the concrete standard of account balance abundance at dissimilar services, make charging way selection more accurately, rationally.
Figure 6 shows that the flow chart of charging method embodiment of the present invention, its idiographic flow is as follows:
After session processing module 21 in the credit control client terminal 2 receives the service request of terminal transmission, pretreatment module 11 in credit control server 1 sends the beginning conversation request, this begins to carry in the conversation request terminal user identification and reserves amount with request, supposes that this user ID is 1301111111111 (steps 201).
Pretreatment module 11 is obtained user ID 1301111111111 from the beginning conversation request, and this user ID 1301111111111 is sent to session control module 12 (step 202).
Session control module 12 sends to authentication module 13 with user ID 1301111111111, and indication is carried out authentication (step 203) to the remaining sum on the account of user ID 1301111111111 correspondences.
Authentication module 13 is obtained the account balance corresponding with user ID 1301111111111 from information storage module 14, and judge that this account remaining sum is whether sufficient and whether need the amount that terminal is used is limited, the standard of supposing the remaining sum abundance predesignated is that remaining sum on the account is greater than 50.00 yuan, the threshold value that need limit the amount that terminal is used is 100.00 yuan, whether then judge the account balance corresponding greater than 50.00 yuan and whether greater than 100.00 yuan, and the authentication result information that whether sufficient account balance is and the judged result feedback information that whether needs the amount that terminal is used is limited are to session control module 12 (step 204) with user ID 1301111111111.
If the account balance abundance, then to adopt the back charging ways be user's requested service of 1301111111111 (that is: step 13) of chargeing to user ID to 12 controls of session control module.
If account balance is inadequate, then adopt to reserve charging way (that is: the step 14) of chargeing, that is: reservation process module 15 is under the indication of session control module 12, reserve and the corresponding reservation amount of money of request reservation amount from the account of user ID 1301111111111, if it is exactly amount of money unit that amount itself is reserved in this request, then directly reserve this reservation amount of money, if it is non-amount of money unit that amount is reserved in request, then computing module 16 calculates according to the rate of Freight Basis memory module 18 storages under the indication of session control module 12, obtain and ask to reserve the corresponding reservation amount of money of amount, reservation process module 15 is reserved this and is reserved the amount of money then, and feeds back the amount of successfully reserving to session control module 12.The amount that this success is reserved can be the duration or the flow of service, for example: 20 minutes or 20M.(step 205).
Pretreatment module 11 is according to the indication of session control module 12, sending the beginning conversation request to session processing module 21 replys, this begins to carry user ID 1301111111111 and approval credit rating in the conversation request answer, and the approval credit rating is the amount of successfully reserving (step 206).
After monitoring identification module 22 received the conversation request answer, whether whether the identification account balance enough sufficient to determine when service is provided to terminal need the volume of terminal use is limited.The account balance abundance can identify by the account balance insufficient information, this account remaining sum insufficient information can be presented as in the conversation request answer does not carry the approval credit rating, also can be that a value is the sufficient sign of genuine account balance, can also be approval credit rating, for example: greater than 1440 minutes the duration of call of duration of call threshold value 3000 minutes greater than a certain default threshold values that need limit to the amount that terminal is used.Monitoring identification module 22 identifies and carries the approval credit rating that is not more than the threshold value that need limit the amount that terminal is used in the answer of beginning conversation request, judges further whether the approval credit rating is zero (step 207).If zero, then refusing provides service to terminal, finish service procedure (step 221).
If it is non-vanishing, then service providing module 24 is according to the indication of monitoring identification module 22, provide its requested service to user ID for the terminal that 1301111111111 user uses, simultaneously, whether whether 23 pairs of these terminals of monitoring module finish to use service to use up with the approval credit rating to monitor (step 208).
The terminal of judging monitoring module 23 finishes to use service and approval credit rating to use up in two incidents, and whether terminal finishes to use service formerly (step 209).
If terminal finishes to use service formerly, then session processing module 21 sends end session request to pretreatment module 11, and this end session request carries user ID 1301111111111 and terminal actual use amount (step 210).
Session control module 12 indication reservation process modules 15 discharge reserved the amount of money (step 211) from the request that user ID 1301111111111 accounts reserve last time.
Session control module 12 indication deduction modules 17 are from user ID 1301111111111 accounts deduction and the actual corresponding amount payable of amount of using, if should reality use amount itself be exactly amount of money unit, then directly deduct this amount payable, if actual use amount is non-amount of money unit, then computing module 16 calculates according to the rate of Freight Basis memory module 18 storages under the indication of session control module 12, obtain and the actual corresponding amount payable of amount of using, deduct module 17 these amounts payable (step 212) of deduction then.
After deducting successfully, pretreatment module 11 sends end session request to credit control client terminal 2 and replys (step 213) according to the indication of session control module 12.
If the approval credit rating uses up formerly,, wherein carry the request reservation amount (step 214) that user ID 1301111111111, terminal actual use amount and request are reserved again then to pretreatment module 11 transmission intermediate conversational request.
Session control module 12 indication reservation process modules 15 discharge the reservation amount of money of reserving from user ID 1301111111111 accounts last time (step 215).
Session control module 12 indication deduction modules 17 are from user ID 1301111111111 accounts deduction and the actual corresponding amount payable of amount of using, if should reality use amount itself be exactly amount of money unit, then directly deduct this amount payable, if actual use amount is non-amount of money unit, then computing module 16 calculates according to the rate of Freight Basis memory module 18 storages under the indication of session control module 12, obtain and the actual corresponding amount payable of amount of using, deduct module 17 these amounts payable (step 216) of deduction then.
Session control module 12 indication reservation process modules 15 are reserved again, that is: reservation process module 15 is under the indication of session control module 12, reserve and the corresponding reservation amount of money of request reservation amount from the account of user ID 1301111111111, if it is exactly amount of money unit that amount itself is reserved in this request, then directly reserve this reservation amount of money, if it is non-amount of money unit that amount is reserved in request, then computing module 16 is under the indication of session control module 12, rate according to 18 storages of Freight Basis memory module calculate, obtain and ask to reserve the corresponding reservation amount of money of amount, reservation process module 15 is reserved this and is reserved the amount of money then, and feeds back the amount of successfully reserving to session control module 12.The amount that this success is reserved can be the duration or the flow of service, for example: 20 minutes or 20M (step 217).
