Description

Real-time cost control service realization method, service control point and service exchange system

technical field

The invention relates to the technical field of intelligent network services, in particular to a method for realizing real-time fee control services, and a corresponding service control point and service switching system.

Background technique

Due to the continuous development and improvement of various communication services, more and more real-time cost control services are being applied in the communication field. Typical real-time cost control services include mobile prepaid services (such as GSM CAMEL prepaid services and CDMA prepaid services, etc.) , Fixed (telephone) prepaid services and (dial-up) Internet card prepaid services, etc. Since the real-time fee control service is characterized by real-time fee control, the system needs to find the currently set fee rate to calculate the service connection time available to the user according to the relevant information of the user account before the service is connected, and then according to the calculated This calculation process is called cost budget; when the business connection is completed (such as the user hangs up or disconnects the dial-up connection, etc.), the system calculates the exact cost according to the actual business connection time and deducts it. This calculation process is called fee calculation.

Please refer to Figure 1, which is a schematic diagram of the main implementation process of implementing real-time cost control services in the communication system, and its main implementation process is as follows:

The intelligent service logic entity in the communication system (such as the service control point SCP in the intelligent network, etc.) performs authentication and authentication processing on the user according to the relevant user information stored in its own database when the user makes a service request, and conducts the authentication process on the requesting user. Expense budget processing, and then indicate the current available time or available fee information of the requesting user to the service switching system for service connection processing based on the fee budget result, and the service switching system will send the request to the user according to the available time or available fee information indicated by the intelligent business logic entity The requested business is continued, and the following two situations may occur during the connection process:

Scenario 1: The service is connected normally, and the service switching system monitors the available time or fee information for the user. When doing business, report the normal duration or usage fee of this business to the intelligent business logic entity for subsequent fee calculation processing;

The second situation: the service is not connected normally, for example, because the called user is busy, does not answer, the network cannot be connected, or the caller actively releases the service before the connection, etc., the service will not be connected normally, because in this case The length of the service connection time is 0, and the communication fee will not be charged to the user, so this kind of service request can be defined as false traffic. In the case of false traffic, the service switching system will report information such as service connection time (0) or fee (0) to the intelligent service logic entity, and the service connection time received by the intelligent service logic entity is (0) Or the cost calculation process will not be performed after the report with the cost (0).

At present, due to many reasons such as tariffs and user habits, there is a large proportion of false traffic in the existing telecommunications services (accounting for about 30% to 70% of the total business volume of telecommunications), and for these large amounts of false traffic, Intelligent business logic entities also need to perform cost budget processing in advance, and intelligent business logic entities perform complex cost budgeting for a large number of false traffic is an important part of consuming system processing resources, that is, intelligent business logic entities perform complex cost budgeting for a large number of false traffic The expense budget of a large amount of system processing resources will be wasted.

Detailed ways

The main design idea of the technical solution of the present invention is that the intelligent service logic entity (such as the SCP in the mobile intelligent network, etc.) first performs authentication processing on the user after the user initiates a communication service request, and no longer budgets the user after the authentication is passed Instead, it sends preset monitoring and metering thresholds (such as time slices, etc.) to the service switching system, and the service switching system monitors the connection of communication services requested by users according to the monitoring and metering thresholds; when the communication services are connected normally Next, the intelligent service logic entity performs fee calculation processing according to the application charging report message reported by the service switching system, and in the case that the communication service is not connected normally, the intelligent service logic entity does not need to perform any additional processing.

The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solution of the present invention will be described in detail below in conjunction with each accompanying drawing.

Please refer to Fig. 2, this figure is the main realization principle flowchart of the realization method of the real-time expense control service of the present invention, and its main realization process is as follows:

Step S10, pre-store a certain monitoring metering threshold on the intelligent service logic entity side; wherein the intelligent service logic entity can be a service control point (SCP, ServiceControl Point) in the mobile intelligent network;

The determined monitoring and metering threshold is preferably the time slice length that can be supported by the user's remaining fee and can complete the communication service connection process, or the service flow value that can be supported by the user's remaining fee and can complete the communication service connection process. For example, pre-determining a reasonable time slice length as the monitoring metering threshold, the determined time slice length must meet the following conditions:

a. The vast majority of users have enough remaining fees to complete the communication service connection within this time slice length. This is to reduce the user fee to support the communication service connection threshold, and optimize as many communication service requests as possible. Because the users whose fees are less than the communication service connection within this time slice still need to process the expense budget;

b. The connection time for most of the communication services requested by users is shorter than this time slice length. This is to reduce the introduction of additional signaling interaction, because the service switching system generally needs to report the relevant connection after the time slice length is reached. Send time information or use cost information to SCP so that SCP can re-calculate the cost.

Step S20, when a user requests a communication service, the intelligent service logic entity indicates the above-mentioned determined monitoring and metering threshold to the service switching system; in general, the intelligent service logic entity will carry the monitoring and metering threshold in the application charging (AC, Apply Charging) message indicated to the service switching system;

In step S30, the service switching system performs connection processing on the communication service requested by the user based on monitoring and metering threshold monitoring delivered by the intelligent service logic entity.

Please refer to Fig. 3, this figure is a schematic diagram of the processing process of false traffic and no false traffic in the method of the present invention, wherein the service switching system is when the communication service requested by the user is not normally connected (when the false traffic occurs) , immediately report the message that the service connection time is 0 or the usage fee is 0 to the intelligent service logic entity, wherein the service switching system can carry the information that the service connection time is 0 or the usage fee is 0 in the application charging report (ACR , Apply Charging Report) message to the intelligent business logic entity; after the intelligent business logic entity receives the message that the service connection time is 0 or the usage fee is 0, it ignores the charge calculation process for the user. In this way, the cost budget processing for users with false traffic is avoided, thereby achieving the purpose of saving system processing resources.

The embodiment corresponding to the situation that the above-mentioned communication service is not connected is as follows:

1. The SCP first sends the Apply Charging message to instruct the SSP to monitor the maximum duration of the communication service connection as 100 seconds;

2. Before the maximum monitoring time slice length arrives, for unconnected communication services (communication services not connected due to reasons such as the called user being busy and not answering) calls, the SSP has already reported the Apply Charing Report message to the SCP ( The maximum time for the SSP to report the Apply Charing Report message to the SCP is 60 seconds), and the service connection time carried in the reported Apply Charing Report message is 0 or the usage fee is 0, then after the SCP receives the Apply Charing Report message , the call is released immediately.

When the service switching system (such as the service switching point SSP) is normally connected to the communication service requested by the user, it can be processed in the following two ways:

The first type: before the monitoring and metering threshold issued by the intelligent service logic entity (such as SCP) is exhausted, the service switching system reports the service connection time or usage fee message to the intelligent service logic The communication time or usage fee is carried in the ACR message and reported to the intelligent business logic entity;

The intelligent service logic entity then calculates the user's fee according to the service connection time or usage fee message reported by the service switching system; and indicates the user's current available time or available fee message to the service switching system according to the fee calculation processing result; Wherein the intelligent service logic entity can carry the user's current available time or available cost in the AC message to indicate to the service switching system;

The service switching system continues to monitor and process the communication service requested by the user according to the user's current available time or available cost indicated by the intelligent service logic entity.

An example corresponding to the above-mentioned first processing method is as follows:

1. The SCP first sends the Apply Charging message to instruct the SSP to monitor the maximum duration of the communication service connection as 100 seconds;

2. When the maximum monitoring time slice length is reached, if the SSP still continues the call, it will immediately report the Apply Charing Report message to the SCP, and the Apply Charing Report message carries the communication service connection time length information or usage fee information;

3. According to the received Apply Charing Report message, the SCP re-calculates the fee for the user, and indicates the fee calculation result to the SSP, so as to cover the maximum monitoring time slice length indicated above, and the SSP continues to monitor the call according to the new instruction of the SCP. continue.

The second type: the service switching system does not report the ACR message when the monitoring and metering threshold issued by the intelligent service logic entity is exhausted;

If the intelligent business logic entity has not received the service connection time or usage fee message fed back by the service switching system when the monitoring metering threshold is exhausted, it will assume that the communication service requested by the user has been connected normally, and immediately calculate the fee for the user Processing; and according to the cost calculation result, indicate the user's current available time or available fee to the service switching system; wherein the intelligent service logic entity can carry the user's current available time or available fee in the AC message to indicate to the service switching system;

The service switching system continues to monitor and process the communication service requested by the user according to the user's current available time or available cost indicated by the intelligent service logic entity.

An example corresponding to the above-mentioned second processing method is as follows:

1. The SCP first sends the Apply Charging message to instruct the SSP to monitor the maximum duration of the communication service connection as 100 seconds;

2. When the maximum monitoring time slice length is reached, if the SCP does not receive the Apply Charing Report message reported by the SSP, the default is that the call has been connected, and the user will be charged again, and the result of the charge calculation will be indicated to the SSP to cover the previous ones. Indicates the maximum monitoring time slice length, and the SSP continues to monitor the connection of the call according to the new instruction of the SCP.

Take the mobile intelligent network as an example: the average duration of a call communication service request is about 70 seconds, and the length of the time slice can be preset as 100 seconds, which is calculated according to the highest rate of domestic calls (due to the high cost of international calls and the proportion of Therefore, it is not necessary to optimize the international calls), then the communication fee of 2.79 yuan is required to complete the communication service connection with the preset time slice length of 100 seconds (7 minutes/6 seconds for long-distance + 80 yuan for the basic call fee in the case of roaming) minutes/60 seconds), so it can be configured in the SCP that when the remaining fee balance of the user account is greater than 3 yuan, it can directly send an Apply Charging message to the SSP, instructing the SSP to charge the user with a maximum monitoring time of 100 seconds. The continuation of communication services is monitored. According to the current network statistics, at least 95% of the user accounts have a remaining charge balance greater than 3 yuan, which consumes 15% of system processing resources according to the charge budget, and 99% of all calls are domestic calls and 60% of them are calls The non-normally connected (false traffic) calculation can reduce the system processing resource consumption by 8.5% based on the solution principle of the present invention.

In summary, because there is a large amount of false traffic in the current communication system, it brings an additional burden to the operating environment of the intelligent service logic entity in the intelligent network. Simple adjustments to the budget processing process, without the need to adjust peripheral equipment, can eliminate the system processing resource consumption problem caused by most of the existing false traffic, thereby significantly improving the system processing performance, making the same capacity The business processing system can carry more business users, which better improves the economic benefits.
