Description

Billing method and system for prepaid service

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a charging method and system for a prepaid service. BACKGROUND In an integrated intelligent network system, a call flow is processed as follows: First, a Mobile Switch Center (MSC)/Service Switch Point (SSP) triggers a Service Control Point (SCP). In the call process, the call process determines the remaining amount of the user, and calculates the length of time that the user can allow the call according to the charging plan and the remaining amount of the current call. The SCP sends the application charging according to the time period set by the system (Apply) Charging, AC) Request SSP charging control to the SSP. After the set time period is over, the SSP will report the Apply Charging Report (ACR) to the SCP for the 4艮 call duration. The SCP accumulates the call. The duration is until the end of the call, and then the SCP charges the cost of the call according to the total call duration, and deducts the user's fee. The process is as shown in FIG. As shown in Figure 1, when the user forwards, two call flows need to be generated simultaneously for one user, one is the called process, and the other is the forwarding process. Each process separately charges the call duration of each process according to the remaining amount of the user, and the SSP monitors the call flow. When one process call ends, the remaining amount of the user is deducted, and when another process call ends, At this point, the user's balance has changed, and the user's original balance is reduced by the amount of the previous call process. The user's balance is not the original calculation time, so when the deduction is made, the overdraft problem will occur. The problem of cost overdrafts that may occur when such prepaid users are in the call forwarding usually does not allow the prepaid users to have a forwarding function. However, this obviously does not satisfy the user's need for business diversification; another solution It is to solve this problem free of charge for the called process when the transfer occurs. However, this obviously does not satisfy the interests of the operators, and neither of these solutions can effectively solve the problem of overdraft from the front. At present, there is no technical solution that can effectively solve the problem of cost overdraft that occurs when a prepaid user moves forward during a call. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. Accordingly, it is a primary object of the present invention to provide a charging mechanism for a prepaid service to solve the problem of cost overdraft that occurs when a prepaid subscriber makes a call forward. According to an aspect of the present invention, a charging method of a prepaid service is provided. The charging method of the prepaid service according to the present invention includes: in the case that the mobile switching center or the service switching center triggers the first process and the second process of the user, the pre-configured call time period is determined sequentially or simultaneously. The first process amount of the first process and the second process amount of the second process, and the first process amount and the second process amount are reserved in the total amount of the user; at the end of the first process and the second process, The amount is deducted from the total amount of the user according to the user's usage. On the one hand, in the case that the first process amount and the second process amount are determined and reserved in succession, the specific processing flow is: when the mobile switching center or the service switching center triggers the first process, the first time is determined according to the calling time period. The amount of the process, and the first process amount is reserved in the total amount; if the second process is further triggered when the first process is triggered by the mobile switching center or the service switching center, the second process amount is determined according to the calling time period, and is reserved The second process amount is reserved in the remaining total amount after the first process amount. And after the first process amount is reserved in the total amount, the method further includes: determining whether the remaining total amount is sufficient to reserve the second process amount, and reserving the second process amount if the determination is yes, otherwise not reserving the first The second process amount, and terminate the second process. In the above case, the mobile switching center or the service switching center determines the reserved first process amount according to the predetermined first process rate and the calling time period, and determines the pre-determination according to the predetermined second process rate and the calling time period. The second process amount left. The first process and the second process include at least one of the following: a called process, a forwarding process, and a general packet radio service network service process. On the other hand, in the case that the first process amount and the second process amount are simultaneously determined according to the call time period, the specific processing flow is: when the mobile switching center or the service switching center triggers the first process and the second process, The pre-configured call time period and the total process rate determine the total process amount of the user, and reserve the total process amount in the total amount of the user, wherein the total process rate is the predetermined first process rate and the predetermined number The sum of the rates of the two processes, the first process is the called process, and the second process is the call forwarding process. Specifically, the process of triggering the first process and the second process of the user by the mobile switching center or the service switching center is specifically: if the second process is an unconditional call forwarding process, triggering the second process while triggering the first process; or If the second process is a conditional call forwarding process, when the first process is triggered, the fee of the first process is first determined according to the rate of the first process, and in the case that it is determined that the forwarding needs to be performed, The total process amount is determined based on the total process rate. In addition, the mobile switching center or the service switching center determines the reserved first process amount according to the predetermined first process rate and the calling time period, and determines the rate and the calling time period according to the predetermined second process. The second process amount reserved. In addition, at the end of the first process and the second process, the mobile switching center or the service switching center reports the application charging report to trigger the deduction of the amount. According to another aspect of the present invention, a billing system for a prepaid service is provided. The charging system of the prepaid service according to the present invention includes: an intelligent service charging control module, configured to, according to the pre-configured call time, when the mobile switching center or the service switching center triggers the first process and the second process of the user The segment determines the first process amount of the first process and the second process amount of the second process sequentially or simultaneously, and requests the platform business logic processing control module to reserve the first process amount and the second amount in the total amount of the user. The amount of the process; the platform business logic processing control module, configured to provide the first process of the service to the user and the second process of the service, store and update the reserved first process amount and the second process amount, and in the first process and the first At the end of the second process, the amount is deducted from the total amount according to the user's business usage. Wherein, in the case that the intelligent service charging control module applies to the platform business logic processing control module to reserve the first process amount and the second process amount in the total amount of the user, the intelligent service charging control module is configured according to the first The rate of the process and the calling time period determine the reserved first process amount, and determine the reserved second process amount according to the predetermined second process rate and the calling time period. Wherein, when the intelligent service charging control module applies to the platform business logic processing control module to reserve the first process amount and the second process amount in the total amount of the user, the intelligent service charging control module is configured according to the calling time period and The total process rate determines the total process amount of the user, and reserves the total process amount in the total amount of the user, wherein the total process rate is the sum of the rate of the predetermined first process and the rate of the predetermined second process. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention are described with reference to the accompanying drawings. The features of the embodiments and the embodiments of the present invention may be combined with each other if they do not conflict. In an embodiment of the present invention, a charging method for a prepaid service is provided. As shown in FIG. 2, the charging method of the prepaid service according to the embodiment of the present invention includes: Step S202: In the case that the mobile switching center or the service switching center triggers the first process and the second process of the user, according to the pre-configured The call time period determines the first process amount of the first process and the second process amount of the second process, and reserves the first process amount and the second process amount in the total amount of the user; Step S204, at the first At the end of the process and the second process, the amount is deducted from the total amount of the user based on the usage of the user. Specifically, the amount of money can be reserved in the following two ways. In the first method, the first process amount and the second process amount are determined and reserved. The process is specifically: when the mobile switching center or the service switching center triggers the first process, the first process amount is determined according to the calling time period, and the total amount is The first process amount is reserved; if the second process is further triggered when the mobile switching center or the service switching center triggers the first process, the second process amount is determined according to the calling time period, and the first process amount is reserved. The second process amount is reserved in the remaining total amount. The first process and the second process may be various processes that can be executed in parallel: for example, the called process, the forwarding process, and the general packet radio service network service process (for example, accessing the Internet through GPRS). And after the first process amount is reserved in the total amount, the method further includes: determining whether the remaining total amount is sufficient to reserve the second process amount, and reserving the second process amount if the determination is yes, otherwise not reserving the first The second process amount, and terminate the second process. Preferably, the mobile switching center or the service switching center can determine the reserved first process amount according to the predetermined first process rate and the calling time period, and according to the predetermined second process rate and call time. The segment determines the second process amount to be reserved. Through the processing of the first method, the problem of overdraft can be effectively avoided in the case where multiple processes simultaneously call in the prepaid service. For example, referring to FIG. 3, for a plurality of call flow eight and B processes, the call sent by the A process first calculates the call duration of the A process according to the remaining amount S of the user, and then according to the configured call time period. Calculate the call cost A1 of this time period and record it in a platform data (can also be read for other processes). The A process reserves this fee and cannot be used by other processes. After the B 3⁄4 u route is sent, the user's remaining amount is first queried, and then the amount reserved for the A 3⁄4 u process is checked. The difference between the two is (S - A1 ), which is the current fee that can be used in the B process. Calculate the call duration based on this cost, and then calculate the cost of the B process for this time period based on the configured time period. The B process also reserves this fee, does not allow other processes to use, and is added to the platform's data. Preferably, the A process reports the ACR after the time period to the time of the delivery. The service re-query the current user balance minus the current amount of all the process withholding, calculate the remaining balance, the amount currently available for the A process, reserve the amount according to the configured time period, and accumulate the time period fee to the platform parameter. in. The B process also repeats the corresponding operations. Thus, A and B alternately reserve expenses, that is, subtract the amount A1, A2, ... of the process A from the total amount S, and subtract the amount B1, B2, ... of the process B until the user balance is deducted or the user Hanging up will not cause overdraft problems. Finally, at the end of the first process and the second process, the mobile switching center or the service switching center applies for a charging report to trigger the deduction of the amount. The second method determines the first process amount and the second process amount according to the calling time period, and the processing process is specifically: when the mobile switching center or the service switching center triggers the first process and the second process, the pre-configured call is performed. The time period and the total process rate determine the total process amount of the user, and reserve the total process amount in the total amount of the user, wherein the total process rate is the predetermined first process rate and the predetermined second process fee. The sum of the rates, the first process is the called process, and the second process is the call forwarding process. Specifically, the process of triggering the first process and the second process of the user by the mobile switching center or the service switching center is specifically: if the second process is an unconditional call forwarding process, triggering the second process while triggering the first process; or If the second process is a conditional call forwarding process, when the first process is triggered, the fee of the first process is first determined according to the rate of the first process, and in the case that it is determined that the forwarding needs to be performed, The total process amount is determined based on the total process rate. Thereafter, at the end of the first process and the second process, the mobile switching center or the service switching center applies for a charging report to trigger the deduction of the amount. Specifically, for the setting of the charging scheme of the called process and the forwarding process, the usual processing method in the related art is to charge the call duration according to the balance of the user and the charging scheme of the respective process, and independently issue the call duration. AC to SSP to monitor calls. In the second mode, the charging scheme MS (that is, the above-mentioned total process rate) is added, and the fee of the charging scheme is corresponding to the rate corresponding to the called process charging scheme MT and the forwarding process charging scheme MF. The sum of the rates, in the two processes of the called process and the forward process, the respective call durations are charged by the MS charging scheme, and then the call request AC is sent to the SSP according to the configured time period, and the call is monitored by the SSP. . When the call process ends or the user balance is exhausted, the last ACR 4 on the SSP reports the call duration. The called process calculates the called process usage fee according to the MT charging plan, and deducts the fee. The forwarding process calculates the usage fee of the forwarding process according to the MF charging scheme, and deducts the fee. The cost of the two deductions is exactly the same as the call duration and the MS billing plan. This solves the overdraft problem of the forward process in the case of simultaneous billing of the called process and the forward process. The billing process is shown in Figure 4. In Figure 4, after the called process and the forward process are triggered, the duration of the call is calculated according to the balance and the total process rate, thereby controlling the called process and the forwarding process; when the user balance is exhausted or hangs up Next, the called process and the forward flow process calculate the fee according to the total call duration and the respective rates (the rate of the called process is MT, and the rate of the forward process is MF), and the charge is deducted. In practical applications, the processing of this embodiment mainly needs to modify and modify the integrated intelligent network service, and the four tampering specifically involves several aspects, that is, the corresponding charging scheme needs to be added, and the tampering forward process and The calculation duration of the called process, the modification of the forwarding process and the deduction method of the called process, and the configuration of the corresponding charging scheme are added to the interface.

(1) The change of the billing plan: The forward transfer process can be divided into two categories: unconditional forward and conditional forward according to the user's forwarding method. For conditional forward, it can be refined into: no response. Forwarding, unreachable forwarding, user busy forwarding, etc. The core network is different for unconditional forwarding and conditional forwarding. The signaling routing is also different, so for unconditional When transferring and conditional forwarding, the cost of the user also requires the service to be flexibly configured. The original service has the following types of charging schemes: Unconditional Forwarding Accounting Scheme (MT_NoCondition) of the called process, conditional forwarding charging scheme of the called process (MT_Condition), forward-flowing process unconditional forward-off charging scheme (MF_NoCondition) and forward-flowing process conditional forwarding charging scheme (MF-Condition) and other related four charging schemes. In this embodiment, two charging schemes need to be added: one is the total flow unconditional forward charging scheme (MS_NoCondition), and when the jib accounting scheme is configured in the charging system, attention should be paid to configuring the jt匕 charging scheme. The cost used is exactly the sum of the fees of the unconditional forwarded billing plan of the called process and the unconditional forwarded billing plan of the forwarding process. The other is the general process conditional forwarding billing scheme (MS-Condition). Similarly, when the billing system is configured with the jib billing scheme, the cost of configuring the jt匕 billing plan is just the conditional pre-revolution of the called process. The fee plan and the forwarding process are combined with the conditional forward billing plan. After a special configuration such as the billing system, the service can control the call flow according to the new billing method. In the fee class of the configuration scheme of the charging scheme of the service system, data such as the call type, call index, and charging scheme of the MS_NoCondition and the MS-condition are added. Also add a control switch in a maskfeeclass table to control whether the interface is allowed to display this billing plan. For example, setting it to 1 means allowing the interface to be displayed and configured. Setting it to 0 means that the interface display and configuration are not allowed. For the tampering of the billing system, only the configuration data of the two billing schemes is added, and the data structure of the billing system does not need to be falsified. The method of adding the billing scheme is the same as the method of adding other billing scheme data. .

(2) Modification of the charging duration method: When the user turns forward, the SSP first triggers the called process of the user. At this time, the called process does not know whether the user needs to forward, so for the called process at this time According to the remaining amount of the user, the call duration is calculated by the normal called process charging scheme, and the AC is sent to the SSP according to the length of the AC configured by the service, and the called call process is monitored, if it occurs. Forward, in the forward flow, the business inserts forward information into a data table. After the first ACR of the called process is sent, it will query the data table to determine whether the forwarding process occurs. If it occurs In the forwarding process, the called process will re-account according to the MS-NoCondition or MS-condition, and the AC will be sent according to the set AC duration. If the user applies for an unconditional forward, the forward process will be triggered immediately, without waiting for the current status of the user in the called process. In the forward process, if the user sends the unconditional forwarding process, the data will be based on the MS. — NoCondition accounting scheme to calculate the call duration of the forwarding process, although the called process is based on the call duration delivered by the normal called process charging scheme, but due to the forwarding process and the called flow The process starts and ends at the same time, so the call duration of the called process is also controlled by the call duration of the forward process, provided that the cost of the general MS-NoCondition is greater than the cost of the normal called process. The forwarding process sends an AC to the SSP to request to monitor the call flow according to the calculated call duration and the length of time that the service is configured to deliver the AC. If the user applies for conditional forwarding, whether the forwarding process triggers the status of the user in the called process, for example, the user applies for a no-reward forward, in the called process, if the called process is within the set time If the user does not answer, the core network will initiate the forwarding process. If the user applies for unreachable forwarding, in the called process, the called user cannot be connected, and the core network will initiate the forwarding process. In the conditional forwarding process, the service calculates the call duration of the forwarding process according to the MS-condition charging scheme, and the unconditional forwarding process. Only after the forwarding process is turned on, the user's called process begins. Billing. So the call duration for both processes is the same.

(3) 4 tampering of the deduction method: After the AC time of the service setting is reached, if the user does not hang up or the balance is sufficient, 4 艮 ACR on the SSP gives the SCP 4 艮 call duration, at this time ACR The logo is not the last one. Until the user hangs up or the balance is used up, the SSP will report the last ACR to the SCP. When the service receives the last ACR, it starts to calculate the call duration used by the user time, and then calculates the fee used by the user according to the charging scheme. As shown in Figure 5, in the called process, after the MSC/SSP triggers the service according to the called contract, the called process will be triggered. At this time, the SCP will follow the remaining amount and the MT-NoCondition (MT) charging scheme. To calculate the duration of the called process, and send the AC to the MSC/SSP; after the set time arrives, the MSC/SSP sends 4 ACR to the SCP; after the SCP learns that the forward has occurred, the total flow rate will be (MS) calculates the duration and delivers a new AC; when the user hangs up, or the user balance is exhausted, the MSC/SSP will be the last ACR, and the SCP will calculate the charge based on the total duration and MT. Fee, the call ends. In the above-mentioned called flow, since the called flow is not known to be the called flow of the forwarding process, the ordinary called process charging scheme used when the charging duration is issued is delivered. In the called process, the service will judge whether the forwarding occurs according to the forwarding information inserted in the forwarding process. If the unconditional forwarding occurs, the called process is calculated according to the duration of the call and the MT-NoCondition charging scheme. Call the cost of the process, and deduct the fee; If a conditional forward occurs, the called process reverses the use fee of the called process according to the call duration and the MT-condition charging scheme, and deducts the fee. As shown in Figure 5, in the forwarding process, after the MSC/SSP triggers the service according to the supplementary service, the forwarding process will be triggered. At this time, the SCP will obtain the total process rate according to the remaining amount and MT + MF ( MS) The billing scheme is used to control the duration of the call, thereby controlling the called process and the forwarding process, and issuing an AC to the MSC/SSP; after the set time arrives, the MSC/SSP sends an ACR to the SCP, in response to the 4艮ACRSCP, SCP continues to send AC to MSC/SSP; When the user hangs up, or the user balance is exhausted, the MSC/SSP will be the last ACR, and the SCP will only count the total duration and MT. Calculate the fee and deduct the fee, and the call ends. In the forwarding process, if the user hangs up or the balance is used up, the unconditional forwarding will calculate the usage fee according to the call duration and the MF-NoCondition billing plan, and deduct the fee; And the MF- Condition billing plan to calculate the usage fee and deduct the fee. Since MS—NoCondition is the sum of MT—NoCondition and MF—NoCondition; MS—Condition is the sum of MT—Condition and MF—Condition, so that the user balance can be fully utilized and no overdraft can occur. System Embodiments According to another aspect of the present invention, a billing system for a prepaid service is provided. As shown in FIG. 6, the charging system of the prepaid service according to the present invention includes: an intelligent service charging control module 602, configured to trigger a first process and a second process of the user in the mobile switching center or the service switching center. In the case that the first process amount of the first process and the second process amount of the second process are determined sequentially or simultaneously according to the pre-configured call time period, and the platform business logic processing control module 604 applies to the user in sequence or simultaneously. The first process amount and the second process amount are reserved in the total amount; the platform business logic processing control module 604 is configured to provide the first process of the service and the second process of the service to the user, and store and update the reserved first process amount. And the second process amount, and at the end of the first process and the second process, the amount is deducted from the total amount according to the user's business usage. In practical applications, there are two specific tampering schemes: If the scheme 1 is used for billing, the following can be modified for the existing intelligent services and supporting platforms: Modifying the intelligent service charging control module in the related technology, so that the intelligent service has the ability to apply for the reserved call amount amount in the charging control of the call, and the intelligent service needs to obtain the corresponding user reservation from the platform during the charging control of the call. The amount of the call charge, and calculate the available balance after the reserve amount is removed; for the platform, the platform business logic processing control (SLP) module needs to be modified to provide the function of depositing the reserved call amount for the calling user, and the service can be extracted and released in time. business. In this way, in the case that the intelligent service charging control module 602 applies to the platform service logic processing control module 604 to reserve the first process amount and the second process amount in the total amount of the user, the intelligent service charging control module 602 is configured according to the predetermined The rate of the first process and the calling time period determine the reserved first process amount, and determine the reserved second process amount according to the predetermined second process rate and the calling time period. As shown in FIG. 7, after receiving the call request, the charging system analyzes the charging plan, finds the available balance, and then calculates the available balance by deducting the reserved call charge, and calculates the current call duration and the amount used. The platform data storage area reserves the amount of the call charge (can be released after the call is completed); the last time the call can be sent. As can be seen from FIG. 7, compared with the existing service platform, the implementation solution 1 has very good versatility, and can protect all concurrent deductions from overdraft. If the charging is performed in the second mode, the charging control module and the charging module of the intelligent network service adopt the same rate scheme. The following modifications are required for the original intelligent service. The intelligent service charging control module is modified so that the intelligent service selects the new total rate MS when the charging control of the forward call is made (the rate is the sum of the called and forwarded rates (ie, the above MF+) MT ) ); and, when the smart service is charged after the call is forwarded, the forwarding rate and the duration of the call are still used for calculation (ie, the forward call charge = MF* call duration). It can be seen from FIG. 8 that, by the above modification, the charging system according to the embodiment can calculate the total rate after receiving the call request, and find the available balance, and calculate and deliver the current call duration; After the call end message, calculate the call charge and deduct the bill. In this way, when the intelligent service charging control module 602 requests the platform service logic processing control module 604 to reserve the first process amount and the second process amount in the total amount of the user, the smart The service charging control module 602 determines the total process amount of the user according to the calling time period and the total process rate, and reserves the total process amount in the total amount of the user, wherein the total process rate is the predetermined first process. The sum of the rate and the rate of the predetermined second process. As shown in FIG. 8 , compared with the existing platform, it can be seen that the modification of the implementation scheme 2 is small, and the purpose of avoiding the overdraft of the forwarding process can be easily achieved. It can be seen that the processing design of the present invention is simple and clear, and only needs to be slightly modified in the calculation of the charging scheme, so that the forwarding process and the called process can be simultaneously used, and no modification to the platform is required. The stability has little effect and avoids overdraft problems. A special billing scheme is used to calculate the duration, but the billing scheme is used for billing when deducting fees. In summary, with the technical solution of the present invention, the overdraft problem occurring in the prepaid forwarding service in the related art can be effectively solved, and the interests of the operator are ensured. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalents, and modifications made within the spirit and principles of the present invention. It should be included in the scope of protection of the present invention.
