These drawings and written description are not intended to limit the scope of the disclosed concept in any way, but to illustrate the disclosed concept for those skilled in the art by referring to specific embodiments.

Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

The present invention provides a monitoring method for international calls, which can be realized through the system structure diagram shown in FIG. 1 . As shown in FIG. 1 , the international call monitoring system 100 is composed of three parts, which are an international long-distance exchange 110 , an international long-distance call monitoring device 120 and a national centralized camping account system 130 . The international long-distance exchange 110 is connected to the international long-distance call monitoring device 120 , and the international long-distance call monitoring device 120 is connected to the national centralized camp account system 130 . When a domestic user initiates an international call at home, the international toll switch 110 sends the user information corresponding to the user to the international call monitoring device 120, and the international call monitoring device 120 identifies the user identity through the user information. If the international call monitoring device 120 identifies that the user is not an international roaming user, then the international call monitoring device 120 obtains user information from the national centralized camp account system 130, if there is no such user information, then sends an instruction to the international long-distance switch 110, so that the international long-distance switch 110 intercepts international calls made by users. The international long-distance switch 110 includes international long-distance switches set up by operators in multiple places in China. If there is no such user information, the international long-distance call monitoring device 120 is also used to extract the user's phone charge balance from the national centralized camp account system 130, and for every continuous unit of international calls, the phone charge balance is deducted from the phone fee once to obtain an available balance. When the balance is less than the telephone fee, send an instruction to the national concentrated camp account system 130, so that the national concentrated camp account system 130 cancels the user's international long-distance call authority, and sends an instruction to the international long-distance exchange 110 to disconnect and cut off the international call, so as to intercept the user's calling purposes of international calls.

The technical solution of the present invention and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

With reference to Fig. 2, Fig. 2 is the first embodiment of the monitoring method of the international call of the present invention, the monitoring method of the international call comprises the following steps:

Step S10, when it is detected that the user makes an international call, and the settlement fee of the international call is greater than the preset threshold, obtain the user's call balance and the consumption fee of the international call. The consumption fee is the telephone fee generated by the international call within a unit duration.

In this embodiment, the execution subject is a monitoring system for international calls. For ease of description, the system is used below to refer to the monitoring system for international calls.

The system includes multiple international long-distance switches, and the international long-distance switches are set up all over the country. When the user as the calling party makes an international call, it will be detected by the international long-distance switchboard, that is, the system can monitor the user's international call through the international long-distance switchboard.

When the system detects that the user makes an international call, the system will obtain the settlement fee for the international call. The settlement fee refers to the mutual settlement fee between domestic and foreign telecom operators for making international calls to each other within a unit of time. The unit duration can be minutes, and some more expensive international calls can use N seconds as the unit duration. Different international calls have different billing charges. The system determines the country to which the called party of an international call belongs, based on which country the billing tariff can be determined.

In addition, different international calls correspond to different international toll IDs. The international long-distance identification can be determined from the area code representing the country in the international telephone number dialed by the user, that is, the international long-distance identification can be the international long-distance area code. The system obtains the settlement fee of the international call based on the international call identifier. It should be noted that the system will regularly import the international long-distance area code, the per-minute settlement rate corresponding to the international long-distance area code, and the preset threshold into the system. Therefore, when the system detects that the user makes an international call, it obtains the international call ID to which the international call belongs, and obtains the settlement fee of the international call according to the long-distance ID.

After obtaining the settlement fee, the device compares the settlement fee with a preset threshold. The preset threshold is a relatively large value. If the settlement fee is greater than the preset threshold, it can be determined that the current international call is a high-payment international call, that is, the international call generates a higher fee per unit of time. For example, the preset threshold is 50 yuan/minute, and if the settlement fee of the international call made by the user is 55 yuan/minute, then the international call is a high-payment international call.

When the international call is a high-payment international call, the system obtains the user information, and if there is no such user information, the international call is cut off. If there is user information, the user's call balance and international call consumption charges are obtained. The credit balance refers to the amount in the user's phone account. Consumption tariff refers to the fee for making high-payment international calls within a unit of time, and the fee is billed by domestic operators, that is, the consumption fee is the telephone fee generated by international calls within a unit of time.

Step S20, determine the user's available balance according to the call balance and the telephone charge, wherein, for every unit duration of an international call, the call charge balance is deducted from the telephone charge once to obtain the available balance.

In this embodiment, the system charges for international calls. Specifically, for every unit duration of an international call, the system will deduct one call charge from the current call balance to obtain the available balance. That is to say, the system can determine the user's available balance according to the call balance and consumption charges. The available balance refers to the credit balance that can be used by the user when making international calls. For example, the balance of the user's phone bill is 101 yuan, and the consumption fee is 25 yuan per minute. After the user makes an international call for one minute, the available balance = 101-25 = 76 yuan; after the user makes two minutes of international calls, the available balance = 101 -25-25=51 yuan.

Step S30, when the available balance is less than the telephone charge, cut off the international call.

After the available balance is determined, the system will compare the available balance with the cost of the unit time consumption tariff, that is, compare the available balance with the phone fee. When the available balance is less than the telephone charge, the system can determine that the user's available balance is not enough to support the user to make international calls, that is, if the user continues to make international calls, a high amount of international call charges will be incurred, and the system will cut off the international call.

After the international call is cut off, the user voluntarily hangs up the call, or the called party voluntarily hangs up the call, the user's international call fee will be deducted. In this regard, the system generates a bill based on the difference between the balance of the call charge and the available balance, and the bill includes the difference and the user's phone account. The system then sends the bill to the terminal corresponding to the deduction center, so that the terminal corresponding to the deduction center deducts the difference from the user's call balance according to the bill. The terminal corresponding to the deduction center can be the national centralized camp account system.

In addition, after the international call ends, that is, after the international call is cut off, the calling user hangs up, or the called user hangs up, the system sends a disconnection command to the international long-distance switch, so that the international long-distance switch performs disconnection according to the disconnection command, so as to Cut off international calls. That is to say, cutting off the international call is realized through the disconnection of the international long-distance exchange.

In the technical solution provided in this embodiment, when it is detected that a domestic user makes an international call and the settlement fee of the international call is greater than the preset threshold, the user's call balance and the consumption fee of the international call are obtained. The consumption fee is the international call in the unit The telephone charges generated within the duration, and determine the user's available balance based on the call balance and telephone charges. When the available balance is less than the telephone charge, the international call will be cut off. In the present invention, when the user dials a high-settlement international call whose settlement fee is greater than the preset threshold, the user's call balance is deducted per unit of time, that is, the user's call balance is deducted once for every continuous unit of time for an international call The available balance of the telephone fee is obtained. If the available balance is less than the telephone fee, the international call will be cut off to avoid high international call arrears, that is, to avoid the loss of revenue of the enterprise operating the international call.

Referring to Fig. 3, Fig. 3 is the second embodiment of the method for monitoring international calls of the present invention, based on the first embodiment, step S20 includes:

In step S21, the current phone balance of the user is acquired, and the credit of the user is acquired.

In this embodiment, the user's current available balance consists of two parts, one part is the user's phone balance, and the other part is the amount that the user can owe. The amount that can be owed is related to the credit of the user. The system first obtains the user's current phone balance, and then obtains the user's credit. Credit and phone balance can be obtained in the national concentration camp account device. It should be noted that the phone balance refers to the fee charged to the phone account by the user, and the phone charge balance refers to the sum of the phone balance and the amount of arrears corresponding to the credit.

Step S22, determining the user's arrears amount according to credit.

There is a mapping relationship between the arrears amount and the credit score, and the system can determine the user's arrears amount based on the mapping relationship and the user's current credit score.

Step S23, determine the current available balance of the user according to the sum of the phone balance and the arrears amount.

After obtaining the user's arrears amount, the system calculates the sum of the phone balance and the arrears amount, and the sum of the phone balance and the arrears amount can be used as the user's current call balance.

In the technical solution provided by this embodiment, the system obtains the user's current phone balance, and obtains the user's corresponding credit, and determines the user's arrears amount according to the credit, so that the sum of the arrears amount and the phone balance is determined as the call fee balance.

Referring to Fig. 4, Fig. 4 is the third embodiment of the method for monitoring international calls of the present invention, based on the first embodiment, step S10 includes:

Step S11, when it is detected that the user makes an international call, and the settlement fee of the international call is greater than a preset threshold, the user information corresponding to the user is obtained.

Step S12, when it is determined according to the user information that the user is not an international roaming user, obtain the user's call balance and international call consumption charges.

In this embodiment, the user may be a caller initiated by a domestic user, or may be a caller initiated by a foreign user. If the user is a foreign user, the system has not cut off the authority of international calls. If the user is a domestic user, the system can cut off the international call.

In this regard, when the system detects that the user is making an international call as the calling party, and the settlement fee of the international call is greater than the preset threshold, that is, when the international call is a high-payment international call, the system will obtain the corresponding user information of the user. Specifically, when the international long-distance exchange detects that the user makes an international call, it will send the calling information such as the user's phone number to the international long-distance call monitoring device. The sending format of the caller information includes: No. 7 signaling, SIP signaling, IMS signaling, or signaling in other preset formats.

The international long-distance call monitoring device analyzes the caller information to obtain the user's phone number, such as 186****1111, and the international long-distance call monitoring device obtains the information related to 186****1111 from the national centralized camp account device, and the related information That is user information.

The system authenticates users based on user information. If it is determined in the user information that the user is a domestic user, that is, the user is not an international roaming user (international roaming means that the user is not a domestic user), the system will obtain the user's call balance and international call consumption charges to determine the user Whether there is a high international arrears, if so, cut off the international call.

When the user is determined to be an international roaming user based on user information, the system does not have the authority to cut off international calls. At this time, the system obtains the duration of the international call. If the duration of the call is longer than the preset duration, the system sends an alarm message to the terminal corresponding to the international call operator to which the user belongs. The alarm message is used to remind the user that the cost of making an international call is greater than the preset Set the fee, that is to remind the foreign operator that the user has made a long international call to generate a high amount of arrears. Alarm information can be output in the form of sound, light, etc. For example, the user is a user from country A who roams into country B, that is, the user makes an international call as a calling party in country B, and the settlement fee between country B and the operator of the called international call is 55 yuan/minute. The threshold is set at 50 yuan/minute, and the billing fee is greater than the preset threshold. Therefore, the called international call is a high-billing international call. The system in country B monitors the duration of international calls made by users. The system in country B stores a preset duration, and the preset duration can be 200 minutes. If the system in country B monitors the call time of the user making an international call for more than 200 minutes, the system will send an alarm message to the corresponding terminal of the international phone operator in country A. .

In the technical solution provided by this embodiment, when it is detected that the user makes an international call and the settlement fee of the international call is greater than the preset threshold, the user information corresponding to the user is obtained, and when it is determined according to the user information that the user is not an international roaming user, Then obtain the balance of the user's phone bill and the consumption fee of the international call to determine whether the user has a high international arrears.

In one embodiment, step S20 includes:

Determine whether to store user information corresponding to the user;

When it is determined to store the user information of the user, the available balance of the user is determined according to the balance of the call charge and the telephone charge.

In this embodiment, when determining that the international call made by the user is a high-payment call, the system needs to determine whether the user is a legitimate user. Specifically, if the user is not a legal user, the user information of the user is not stored in the national concentration camp account system, that is, if it is determined that the user information of the user is not stored, the user is an illegal user, and the illegal user makes an international call, and there is an international high The hidden danger of arrears. In this regard, the system determines whether to store the user information corresponding to the user. If it is determined that the user information of the user is stored, then the user's available balance is determined according to the call balance and telephone charges, that is, whether the user is in high arrears is monitored. If it is determined that the user does not store the user's user information, the user is an illegal user, and the system will directly cut off the international call to avoid high arrears for international calls.
