Description

Method for connecting calling user terminal to prepaid service system

Technical field

The present invention belongs to the field of communications, and more particularly to a method for implementing access to a prepaid service system of a telecommunications carrier. Background technique

The basic principle of the prepaid service is that the user is required to advance the communication fee before using the service, and the prepaid service system performs the fee deduction and balance check for the prepaid user who is using the communication service in real time according to the configured charging data, and accurately realizes The communication cost control function for the user.

The prepaid service mainly provides functions such as user call authentication control, real-time charging management, and recharge of call charges. The prepaid service is implemented based on the intelligent network technology and the call preset technology, and firstly requires all switching devices in the local network to provide call preset functions. All the pre-paid subscribers' preset service access codes are connected to the intelligent network platform, and then the intelligent network platform performs call authentication and call charge control processing, and completes the subsequent call process.

However, in actual use, there is a situation in which the user group of the prepaid service provided by an operator is often limited to the carrier. If the users of other operators use the prepaid service provided, there is Problems such as fee settlement and double billing between operators have made it impossible for large-scale pre-paid services to be launched on a large scale, and it is difficult to attract other types of users. This is more obvious for small and medium-sized operators.

For example, when user A of carrier A dials the access code of the prepaid service provided by carrier B, carrier A will charge user A for the call charge of the calling party's access code until the calling user A hangs up and the user A uses the prepaid service of operator B, and the generated call charges are also deducted from the prepaid account, so that user A is charged twice, and for the user, operator B's prepaid service has no tariff advantage. This is very unfavorable for Carrier B's prepaid business. Summary of the invention

The technical problem to be solved by the present invention is to provide an access method for a prepaid service system, which implements a prepaid service system for accessing a calling user terminal to a telecommunication operator according to an access request of a calling user terminal, at the calling party. Under the premise of receiving the free, avoid the settlement of fees between operators and the secondary billing of the caller.

To solve the above technical problem, the present invention provides a method for accessing a calling user terminal to a prepaid service system, including the following steps:

(1) The prepaid service system obtains the number of the calling user terminal according to the access request of the calling user terminal;

(2) The prepaid service system calls back the calling user terminal according to the number of the calling user terminal;

(3) The prepaid service system accesses the prepaid service system to the prepaid service system when the calling user terminal answers.

The invention may further comprise the following steps:

(4) The prepaid service system checks the prepaid account number of the calling user terminal;

(5) The prepaid service system routes the called number according to the called number requested by the calling user terminal;

(6) After the called user terminal answers the call, the prepaid service system connects the calling party and the called party, and starts charging;

(7) The prepaid service system deducts the current call charge from the account of the calling user terminal after the call between the calling party and the called party ends.

The step (1) may include the following steps:

(IA) The calling user terminal calls the access number specified by the prepaid service system, and the call carries the number information of the calling user terminal;

(IB) After the prepaid service system resolves the call, the number of the calling user terminal is recorded, and the calling party is released. The step (1) may also include the following steps:

(la) the calling user terminal sends a short message to the access number specified by the prepaid service system, where the message body carries the number information of the calling user terminal;

( lb) After the prepaid service system parses the short message, the number of the calling user terminal is recorded.

In the step (1), after obtaining the number of the calling user terminal, the method further includes the following steps:

Determining, according to the number of the calling user terminal, whether the user terminal belongs to a user terminal in the system;

If it is the user terminal of the system, the calling user terminal is directly connected to the prepaid service system; if not, steps (2) and (3) are performed.

By applying the invention, not only the access of the prepaid service but also the secondary charging of the calling user is avoided. In many countries where mobile phones are available for free, fixed-service prepaid services can use the access method of the present invention to attract mobile phone users to use prepaid services with low tariffs, which not only expands the user population of the service, but also increases the operator's Operating income. BRIEF abstract

FIG. 1 is a flowchart of accessing a prepaid service system according to an embodiment of the invention. BEST MODE FOR CARRYING OUT THE INVENTION

The prepaid service, in addition to the access service, generally includes functions such as recharging and querying the call charge, but the present invention focuses on providing a new access method, and the specific functional flow in the prepaid process is no longer specific. set forth.

First, let's first analyze the processing flow when users of different operators use prepaid services:

User A of the operator A dials the prepaid service access code provided by the operator B. After the service is accessed, the service system sends a prompt tone to the calling party. At this time, the user A has not dialed the called number, but The calling party considers that the calling party A dials the access code and the voice channel is connected. The operator A dials the access code to the calling party A to start charging. If User A dials the other called party using the prepaid service, the prepaid service will deduct the call charge from the account. Therefore, the fee of user A includes two parts, one is the fee charged by the operator A to dial the access code until the caller hangs up, and the second is the call charge deducted by the prepaid system on the account.

According to the above analysis, if the control system can control the service system to obtain the caller's A number after the caller A requests to access, and then release the caller, then the caller side will think that the call is not connected, so that the caller will not Calling billing, and then using the calling party to receive the free feature, the service initiates a call to the calling party according to the obtained calling information. After the calling party answers, the normal prepaid process is entered. At this time, since the calling user is connected in the answering mode, the operator A does not charge A in the whole process of using the prepaid service. Similarly, the access mode is not limited to dialing the access code mode, and can also use the short message mode to define the account number and the called number identifier in the short message body, and the short message gateway sends the identifier to the service, and the service system can receive the message according to the received message. Content, providing users with a more flexible process.

As shown in FIG. 1 , it is a schematic flowchart of an access method according to an embodiment of the present invention, where a user access request sent by a user terminal includes a mode of dialing an access code and a short message mode:

1. The access procedure of the user terminal dialing the access code mode - Step 101: The user dials the prepaid service access code;

Step 102: The prepaid service obtains the calling number information, and releases the calling party;

Determining, according to the number of the calling user terminal, whether the user terminal belongs to a user terminal in the system; if it is a user terminal of the system, directly connecting the calling user terminal to the prepaid service system; if not, then Step 103 begins execution.

Step 103: The system initiates a call, and calls back to the calling user;

Step 104: Determine whether the calling party is connected;

If not, the callback is abandoned; if it is connected, the process proceeds to step 105: according to the calling number, whether the number has already registered the prepaid account; If the calling party has registered the prepaid account, log in with the account, and go to step 107; if the calling party does not register the prepaid account, go to step 106: prompt the user to enter the account to log in;

Step 107: After verifying that the account is correct, prompting the user to input the called number;

Step 108: After the user inputs the called party, go to step 109: route the called number; Step 1 10: After the called party answers the call, the calling party and the called party call;

Step 111: After the call ends, deduct the cost of the call from the account.

2. Access process in short message mode:

Step 1 12: The calling user sends a short message to the specified number;

Step 113: parse the calling information or the account information or the called information from the short message body; Step 103: The system initiates a call, calls back the calling user, and the calling party answers;

Step 104: Determine whether the calling party is connected;

If not connected, the callback is abandoned; if it is connected, the process proceeds to step 114: determining whether the account information is included in the message body;

If the short message contains account information, it is considered that the user wants to use the account to log in, and the process proceeds to step 116: determining whether the message body contains the called number, if yes, proceeding to step 109, if not, proceeding to step 108;

If the short message does not include the account information, proceed to step 115: query whether the calling number has already registered the prepaid account, and if the prepaid account has been registered, log in using the account, go to step 107; otherwise, go to step 106: prompt the user Enter the account number;

After verifying that the account number is correct, if the message body does not include the called number, proceed to step 108: prompt the user to input the called number, and then proceeds to step 109: routing the called number;
