Description

Call control method and service control device

Technical field

This document relates to but not limited to the field of communications, and in particular to a call control method and a service control device.

Background technique

In order to prevent users from calling malicious overdrafts, operators generally use real-time call control and charging for prepaid users. When the user initiates a call, the operator adopts the intelligent network technology, and uses the real-time call control and the online charging system to authenticate the user, and checks whether the balance in the user's account is sufficient to initiate a call. When the user balance is 0 or less than one call, the real-time call control and online charging system will generally release the call actively. At this point, the user must recharge his prepaid account before continuing to use the service. Such a processing method can control the user to use the service in real time, and ensure that the user does not overdraft, thereby protecting the interests of the operator to the greatest extent. But from the user's point of view, this approach is not optimal. Roughly releasing the user's phone, especially in some urgent situations, the user can't find a convenient recharge channel, which will give the user a bad experience.

To this end, some operators provide a lending function for users to use, users can borrow a small amount of money from the operator online to help users complete the business that needs urgent processing. The amount of the loan will be deducted from the user's account the next time the user recharges. However, these lending functions often require the user to first end the current call and initiate it through other means such as Unstructured Supplementary Service Data (USSD), SMS messaging, and the like. After getting the loan, re-initiate the call. At present, there are two problems in the loan scheme provided by the operator: 1. The user needs to end the already initiated call to borrow, and re-initiate the call after borrowing, and the user experience is not good. 2.USSD, SMS needs to send a specific format request to the prepaid system, including access code, request content, etc., which is not easy to remember and use for the user.

Embodiments of the invention

For a better understanding of the technical solutions of the embodiments of the present invention, the following detailed description will be made with reference to the accompanying drawings and specific embodiments.

Embodiment 1

The call control method of this embodiment, as shown in FIG. 1, includes the following steps:

Step S101: The service control apparatus determines whether the calling party terminal of the call is insufficient after receiving a new call setup request or during the process of processing the currently ongoing call;

In this step, the service control device receives a new call setup request when the caller terminal calls the called party terminal, and when the call is not connected, the call is handed over to the service control device for processing. Handling the currently ongoing call process means that the calling party terminal and the called party terminal have been connected and are in a call state. The insufficient balance here may be that the current balance of the calling party terminal is less than or equal to the preset balance threshold, and the preset preset balance threshold may be a preset value greater than zero, for example, the preset balance threshold is 0, or 5 yuan. , 10 yuan, etc., the specific fixed value can be set according to the specific circumstances, where 0 means that the current user has no available call charges, the setting is greater than 0 in order to prevent interruption during the process or to borrow to a certain extent affect the call, because generally we call It will last for a few minutes, especially when you have some important things to discuss or a conference call, and you will talk for a long time. Setting a larger fixed value is the default balance threshold to avoid interrupting the call in these situations. It can also be the minimum call charge corresponding to the type of call dialed by the current user or the call charge corresponding to a certain time. For example, if the average call time is 3 hairs, then the balance in the calling party terminal account is less than 3 hairs, and the call cannot be made; if the domestic long distance is usually 5 hairs, then if the minimum fee is less than the corresponding call type, the call cannot be made. . Optionally, the call amount corresponding to the call type corresponding to the call type may be set as a preset balance threshold according to the call type, so that the caller terminal has sufficient talk time. Of course, the specific situation can be specifically set according to the needs of the specific calling party. The specific situation may be described by taking the call between the terminal A and the terminal B as an example. In one case, the current balance of the terminal A is zero, and the terminal B is called. The call first goes to the mobile service switching center, and the mobile service switching center gives the call to the call. The service control device, the service control device notifies the online charging system, and the online charging system queries the terminal A account balance to 0, and tells the service control device that the call fails, and the terminal A balance is zero. Since the balance of the terminal A is 0, the service control device judges that the terminal A is in a state in which the balance is insufficient. In another case, terminal A has a certain balance, and calls terminal B. Terminal A and terminal B are in the process of calling, and are local calls, if the local call is 3 cents per minute, due to the call. After a certain period of time, the balance in terminal A is less than 3 gross. At this time, the online charging system will tell the service control device terminal A that the balance is less than 3 gross, and the call cannot be continued. Since the balance of the terminal A is less than 3, the service control device judges that the terminal A is in a state in which the balance is insufficient.

Step S102: When it is determined that the calling party terminal of the call has insufficient balance, the service control device maintains the current call and starts the lending service for the calling party terminal.

In this step, when the service control device determines that the calling party terminal of the call is insufficient, the service control device does not directly release the call, but maintains the current call and starts the loan service for the calling party terminal. Referring to the example in the above step S101, if the balance of the terminal A when initiating a call to the terminal B is 0 or the balance of the terminal A and the terminal B after a certain period of time is insufficient to make a call, the call of the terminal A is continued and started. In the lending business, terminal A obtains the loan amount to make continuous calls. It is worth noting that the loan amount here can be the amount of the loan for the loan, or the length of the call for the loan. It should be understood that the loan amount here refers to the parameter that can make the calling party terminal talk and how long the call can be. Yes. Of course, the size of the loan amount here can be set by a related rule set in advance. For example, the amount of the call charge preset by the loan may be set, such as borrowing 5 yuan, 10 yuan, and 20 yuan, etc., and may be determined according to the selection of the calling party terminal or according to the credit corresponding to the calling party terminal. According to the credit of the calling party terminal, the credit amount of the calling party terminal may be large, and the credit low loan amount is low. It should be understood that the specific loan amount may be specifically set according to the agreement signed with the calling party terminal and the related credit information of the calling party terminal.

Optionally, in the foregoing step S101, when the service control apparatus receives the new call setup request, the service control apparatus determines that the calling party terminal of the call has insufficient balance, including:

After receiving the new call setup request, the service control device sends a call authentication request to the online charging system; the service control device receives the call authentication result fed back by the online charging system; and the service control device determines the call authentication result as the calling party. The terminal balance is insufficient. It is worth noting that the call authentication request here is to ask whether the online charging system can make a call, that is, to query the balance of the calling party account of the online charging system. It should be understood that the authentication request may optionally employ a credit control request as long as it is used to query whether the calling party terminal corresponding to the call can communicate and balance request information. The result of the authentication here refers to whether it is possible to call and why it cannot be called. The authentication result here can be specifically fed back to the service control device through the credit control message response message, which should be understood as long as It is enough to tell the service control device that the message cannot be called and cannot be called.

Optionally, in the foregoing step S101, when processing the currently ongoing call, the service control apparatus determines that the calling party terminal of the call has insufficient balance, including:

The service control device sends a caller terminal balance inquiry request to the online charging system; the service control device receives the balance inquiry result fed back by the online charging system; and the service control device determines that the balance inquiry result is insufficient for the calling party terminal balance. It is worth noting that the balance inquiry request here is to ask whether the online charging system can continue the call, that is, to ask the balance of the online charging system caller account. It should be understood that as long as it is used to query whether the calling party terminal corresponding to the call can talk and balance request information. The result of the balance inquiry here refers to whether or not the call can be continued, and the reason why the call cannot be continued, and it should be understood as long as the message that the service control device cannot continue the call and the reason why the call cannot be continued can be notified.

Optionally, in the foregoing step S102, the service control apparatus starts the loan service for the calling party terminal, including:

The service control device acquires the user loan authorization through the user interaction device; the service control device acquires the call loan from the online charging system; the service control device notifies the mobile service switching center to process the continuous call. Optionally, the service control device acquires the user loan authorization by using the user interaction device, and the service control device notifies the mobile service switching center to connect the current session to the user interaction device. Optionally, the notification message may be an ETC, which should be understood as long as The mobile service switching center allows the user interaction device to establish a connection with the service control device; the service control device sends a loan authorization request to the calling party terminal through the user interaction device; the service control device receives the feedback from the calling party terminal through the user interaction device The loan authorization request response message, the authorization request response message includes information on whether the calling party terminal is authorized, and it should be understood that the loan authorization request and the loan authorization request response message are as long as the calling party terminal can agree through the user interaction device. Messages about the amount of borrowing and the amount of the loan can be used. Obtaining a call loan from the online charging system includes: requesting a borrowing request from the online charging system to apply for a borrowing request to the calling party terminal; receiving a loan request response fed back by the online charging system, and the borrowing request response message includes a calling loan amount, which should be understood as The loan request and the loan request response message may be any message that can obtain a certain loan amount from the online charging system, and the information may be carried in the credit control request and the credit control response message. The service control device notifies the mobile service switching center to process the continuous call, including: the service control device sends the voice channel Turning off the notification message to the mobile service switching center to enable the mobile service switching center to cut off the voice channel between the user interaction devices, and the service control device sends a call processing message to the mobile service switching center to make the mobile service switching center continuously call, and the service control device monitors the call, and should It can be understood that the message disconnection notification message here can be used as long as the mobile service switching center can cut off the message between the user and the user interaction device. Alternatively, the DFC message can be disconnected for the forward connection; the call processing message here can be The mobile service switching center can continuously process the message of the call, and optionally can report the BCSM event RRBE, request the charging AC, and continue the CONTINUE indication. The service control device monitors the call, and the service control device obtains the call duration of the call from the mobile service switching center in real time, and feeds the call duration to the online charging system.

Optionally, in order to better ensure that users can repay loans, prevent malicious borrowing by some users. Before the service control device acquires the user loan authorization through the user interaction device, the service control device further queries the online charging system whether the calling party terminal has the loan right. Of course, it should be understood that when the calling party terminal initiates the lending service, the calling party terminal should open the service or ask the calling party terminal whether to open the service.

In order to facilitate a better understanding of the embodiments of the present invention, the following steps are combined with the current balance of the terminal A to be zero, and the terminal B is called, and the service control device is taken as a service control point as an example for detailed description. The current balance of the terminal A is 0, and the terminal B is called. At this time, the mobile service switching center receives the call, transfers the call to the service control point, and the service control point goes to the online charging system to query the call permission, that is, Whether to process the call subsequently, that is, call authentication; the online charging system finds that the balance in the terminal A account is 0, telling the service control point that the call fails and the reason for the failure is that the balance is 0. After the service control point knows, it initiates a loan permission request to the online charging system, and asks whether the terminal A has the borrowing right. After the terminal A queries through the relevant rules, it tells the service control point whether it has the borrowing right. If so, the service control point Tell the mobile service switching center to let the mobile online switching center establish a connection with terminal A through the user interaction device to obtain the loan authorization of terminal A. For example, tell terminal A that "your current balance is 0. In order to ensure your normal call, whether to start the loan business. If you start, please reply 1, if you don't borrow, please hang up. If you borrow, you can further tell terminal A "Please select the loan amount, reply to the specific amount plus # end, for example, borrow 10 yuan to reply 10#", assuming terminal A authorized loan And the loan is 10 yuan, then the business control point will receive the authorization, then borrow from the online charging system, and borrow 10 yuan, the online charging system is receiving After the loan request to the service control point, the terminal A borrows 10 yuan, and informs the service control point that the borrowing terminal has 10 yuan. After the service control point learns, it tells the mobile service switching center to disconnect the user interaction device from the terminal A, and the call of the terminal A is continuous, that is, the terminal B that is called by the terminal A is analyzed, and the terminal A and the terminal B are passed. The route is connected to make a call.

Embodiment 2

The call control method of this embodiment, as shown in FIG. 2, includes the following steps:

Step S201: When the balance is 0 or the balance is less than one call, the user initiates a call and dials the called number;

Step S202: The mobile switching center MSC needs to trigger the service control point according to the subscription information of the user. The mobile services switching center MSC sends a initiate call attempt Initial DP message to the service control point.

Step S203: The service control point selects the service control point according to the service key parameter in the initiate call attempt InitialDP to process the call. The service control point will initiate caller-related parameters in the caller InitialDP and the location information of the user. The credit control Diameter interface sends a credit control request to the online charging system to authenticate the user and reserve and balance the call.

Step S204: In the case that the user balance is 0 or the balance is less than one call, the online charging system fails to authenticate, and the credit control response is returned to the service control point. The response message contains the reason for the failure because the balance is less than one call.

Step S205: The service control point finds that the user cannot talk because the balance is insufficient, and the call is not released immediately. Instead, the loan authentication message is sent to the online billing system to see if the user can borrow.

Step S206: On the online charging system side, the lending strategy has been set in advance, and the online charging system can determine whether the user can temporarily borrow a small amount of money to urgently use the service according to the situation in which the user uses the service. The judgment condition is configurable, including the user's online time, whether there is any outstanding loan, or whether there is no recharge in the last X days, and the recharge amount is greater than a certain threshold. Through such a strategy, it can be guaranteed that the loan is only provided to the high credit user, and the user is prevented from borrowing maliciously. in case The user is eligible for the loan and the online charging system will return the loan authentication response. The response message contains whether it is possible to borrow and the amount that can be borrowed.

Step S207: In the case that the user can borrow, the service control point sends a temporary connection ETC message to the mobile service switching center MSC, and connects the user's voice path to the independent peripheral. It is noted that the independent peripheral here is A type of user interaction device.

Step S208: The independent peripheral sends a resource indicator ARI message to the service control point to notify the service control point that the network side is ready and user interaction.

Step S209: The service control point sends the user response PAC message to the independent peripheral in advance, instructs the independent peripheral to play the service sound to the user, notifies the user that the current balance is less than one call, and asks the user whether he is willing to borrow a certain amount of money to use the service. .

Step S210: The user inputs his or her own choice through the dual-tone multi-frequency DTMF, accepts the loan or rejects the loan. If the user chooses to reject, the service control point will release the call and the entire process ends.

Step S211: If the user accepts the loan, the service control point sends a loan request to the online charging system to apply for a loan for the user. The online charging system will re-authenticate the user according to the previously set policy.

Step S212: After the authentication is passed, the loan amount is put into the user's account, and a successful loan response is returned.

Step S213: After receiving the successful loan response, the service control point sends off the forward connection DFC to the mobile services switching center MSC, cuts off the voice channel between the mobile service switching center MSC and the independent peripheral, and releases the corresponding interaction on the independent peripheral. Resources.

Step S214: The service control point resends the credit control message to the online charging system for rating and charging the call;

Step S215: At this time, the user has completed the loan, and there is sufficient balance in the account. The online billing system will rate the call and reserve a certain amount from the user's account. The online charging system returns a credit control response message, where the message includes the authentication result and the duration of the call corresponding to the reserved amount;

Step S216: After receiving the response, the service control point sends a request to report the BCSM event RRBE, applies for charging AC, continues CONTINUE, instructs the mobile services switching center MSC to connect the call, and monitors View the call; the MSC performs number analysis on the called number and routes the call to the destination.

Step S217: When the call ends, the calling user or the called user hangs up, and the mobile service switching center MSC reports the BCSM event reporting ERB on-hook event and applies for the charging report ACR call duration to the service control point of the service control point;

Step S218: The service control point sends a credit control (end) request message to the online charging system, where the message carries the actual call duration of the user;

Step S219: The online charging system performs the rating and charging according to the duration of the user's call, and deducts the fee from the user account, and returns a credit control response message to the service control point;

Step S210: Release the call.

In this embodiment, the service control point device is used to perform real-time control on the call initiated by the user. An online charging system is deployed behind the service control point to implement real-time call charge control for the user to use the service. After receiving the service trigger message, the service control point communicates with the online charging system through the internal interface, and sends the call related information and user information to the online charging system. The online billing system rates and balances the call based on the user's account balance. When the user balance is insufficient, the real-time billing system will return a insufficient balance response to the service control point. The service control point authenticates whether the user can borrow through the internal interface to the online charging system. Authentication is carried out through a series of pre-designed rules. These rules are mainly based on the user's past business usage information, which may include the user's online time, whether the user has outstanding loans, and the user's recent recharge. If the user's loan authentication passes, the service control point instructs the switch to connect the call to the independent IP, and controls the independent IP to play the notification tone to the user, asking if the user needs to borrow and the amount of the loan. The user enters his or her choice by pressing the button. If the user chooses to borrow, the service control point call control logic will borrow the user through the internal interface to the online billing system account management module. After the loan is successful, the account management module will increase the amount of the loan in the user account. After the loan is successfully successful, the service control point will resend the call authentication message to the online charging system to rate the user and the call and reserve the balance. At this point, the user account already has money, and the real-time charging system will return an authentication success message to the service control point. The service control point sends a connection command to the switch, and the call is connected to the destination number. During the call, the service control point continues to monitor and control the call, and at the end of the call, the call duration is sent to the online billing system for pricing and deduction. With the call control method in this embodiment, the operator can directly provide the borrowing function for the user in the call in real time. For the user to get a better use of the body The test improves user satisfaction. For operators, it provides innovative services, attracts more users, meets the urgent needs of users, expands the use of lending services, improves the traffic of low-balance users, and increases revenue.
