Description

Feedback method and system for communication billing information

technical field

The invention relates to a communication billing method, in particular to a method for a communication user to quickly acquire communication billing information.

Background technique

With the rapid development of communication technology, various means of communication are becoming more and more popular, and fixed telephone and mobile phone are the main modes of mass communication. At present, the price of communication terminals (such as fixed telephones and mobile phones) is relatively low, and the expenses incurred in communication (such as telephone charges) account for a considerable proportion of the total cost of communications, and the telephone charges in a few months will exceed a telephone Machine costs are already common. Users urgently need to know the occurrence of call charges in a timely manner so as to effectively control call charges. In addition, a small number of criminals use deceptive means to lure users who do not know the truth to make some high-charge calls, causing users to generate high phone charges without knowing it. If users can know the amount of phone charges in time, unnecessary economic losses will be huge. The magnitude is reduced. Telecom operators also hope to provide users with call charge data in a timely manner. On the one hand, it can reduce disputes caused by call charges, and on the other hand, it may be possible to obtain additional income through this value-added service.

However, at present, the voice fee is still a black box for most users, and the total amount is only known when the bill is received every month. If you want to know the specific call charges, you need to go to the special network of the telecom operator to inquire, which is time-consuming and laborious .

At present, there is an external separate meter on the market, which can display the approximate call charge in time. As shown in Figure 1, the meter is connected between the switch and the user terminal. Before using this kind of meter, the user needs to set various rates (billing rules) on the meter, such as how much is the long distance per minute, how much is the local call per minute, etc., when there are many communication types Sometimes, the setting process is quite complicated and cumbersome. When the user dials a call, the meter records relevant information (such as the called phone number), and starts timing simultaneously. When the call ends (hang up), the charging device calculates the cost of the call according to the set charging rules, and displays it to the user. For example, the biller finds that it is a local call by analyzing the called number, and finds the rate of the local call from the preset billing rules, and multiplies the rate by the recorded call time to get the call rate of this call. cost.

Some mobile phones also have a function similar to the above-mentioned meter, and the method of use and working principle are similar. The only difference is that this function is integrated into the mobile phone.

In practical application, the above solution has the following problems: complicated setting, inaccurate billing, and high cost.

The main reason for this situation is that there are many types of services provided by telecom operators, and there are also many tariff conditions. For example, taking long-distance calls as an example, the rates for calls to different places and in different time periods are different. . Moreover, the tariff policy will also change. For example, the long distance in the past was billed by the minute, but now it is billed by the second. Coupled with some promotional activities of telecom operators (for example, during the promotional period, you can enjoy a certain discount for calling during a certain period of time), the billing of communication is very complicated, with many business rules and frequent changes, it is almost impossible for non-professionals Accurately figure out all the billing rules, not to mention setting them accurately in the billing machine.

In addition, even if a very small number of users have the ability and patience to obtain and input these billing rules, the billing device itself cannot be so complicated due to cost considerations.

Because the billing rules cannot be completely accurate, the final calculated call charges cannot be completely accurate.

In addition, since the user needs to pay an additional fee for the purchase of additional equipment, the total communication cost increases.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a communication billing information feedback method and its system, so that the user can obtain the accurate cost information of the call immediately after the end of the call, without adding additional equipment and without additional settings operate.

In order to achieve the above object, the present invention provides a communication billing information feedback method, which includes the following steps when the user ends the call:

A network-side billing device generates communication billing information for the call, and sends the communication billing information to the user terminal;

B. The user terminal receives and displays the communication charging information.

Wherein, in the step B, the user terminal does not ring when receiving the communication charging information.

The network side does not send the ring current signal to the user terminal.

The step B also includes the following sub-steps:

The user terminal judges whether the received data is communication charging information according to the data format, and if so, displays the communication charging information.

The user terminal checks the validity of the received communication charging information.

The network-side billing device may send the communication billing information to the user terminal by means of frequency shift keying or dual tone multi-frequency.

When the user is a recharge user, the communication billing information also includes the recharge balance of the user.

The present invention also provides a communication billing information feedback system, including a network-side billing device and a user terminal,

The network-side billing device is used to generate communication billing information for the call when the user ends the call, and send the communication billing information to the user terminal;

The user terminal is used for receiving and displaying the communication charging information.

Wherein, the user terminal may be a fixed telephone or a mobile telephone.

The charging device on the network side may be a switch.

The network-side billing device does not need to send a ringing signal when sending communication billing information to the user terminal, and the user terminal does not ring when receiving the communication billing information, but can provide a prompt tone according to settings.

Through comparison, it can be found that the difference between the technical solution of the present invention and the prior art is that the real-time billing information on the switchboard of the telecom operator is utilized, and when the user's call ends, the billing information on the switchboard is sent to the user terminal immediately, And the user terminal displays the billing information, and does not send the ring current signal at the same time to prevent the user terminal from ringing. The terminal can flexibly set whether the terminal itself provides a prompt tone after detecting the call charge data. If it is a recharge user, the switch also sends the recharge balance to the user terminal at the same time.

The difference in this technical solution has brought obvious beneficial effects, that is, because the real-time billing information from the telecom operator is used, the accuracy and consistency of the call bill generated by the switch and the call charge displayed on the user terminal are guaranteed. sex. The complex billing rules are maintained by telecom operators without any participation from users. The user only needs to have a telephone set, and does not need to purchase other devices at extra cost, which reduces the communication cost of the user.

The exchange does not send a ring signal to the communication terminal during the transfer of the call charge, so the user terminal will not ring, which conforms to the user's usage habits, and the use process is no different from the normal call, which is convenient for network-wide promotion.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 2 , the communication charging information feedback system includes two parts, a network-side charging device 10 and a user terminal 20 , which are connected to each other.

The network-side charging device 10 is used to generate communication charging information, and send the communication charging information generated by this call to the user terminal 20 through the user circuit interface when the call ends. The charging device 10 on the network side may be a device in a wired communication system (such as a fixed line system) or a device in a wireless communication system. In a preferred embodiment of the present invention, the charging device 10 on the network side is a switch, which is responsible for implementing switching functions for user calls and charging for user calls. In another preferred embodiment of the present invention, the user is a top-up user, and the communication charging information sent by the network-side charging device 10 to the user terminal 20 at the end of the call also includes the user's top-up balance.

The user terminal 20 is used to make a call, and when receiving data from the network-side billing device 10, judges whether the data is communication billing information, and if it is valid billing data, directly displays the communication billing information to the user. The user terminal 20 may be a fixed telephone or a mobile telephone. The user terminal 20 can be either a calling user terminal or a called user terminal, especially in some two-way charging or called charging systems, it is necessary for the called user terminal to display communication charging information.

The specific flow of the communication charging information feedback method will be described below with reference to FIG. 3 .

When the call ends, for example, the calling user hangs up, this process starts.

In step 100, the network-side charging device 10 generates communication charging information, and sends the communication charging information to the user terminal 20 through the user circuit interface. If the user is a recharge user, the network-side charging device 10 also calculates the recharge balance of the user, and sends the recharge balance to the user terminal 20 as part of the communication charging information. The network-side billing device 10 may send communication billing information to the user terminal 20 through frequency shift keying (Frequency Shift Keying, "FSK" for short) or dual tone multifrequency (Dualtone multifrequency, "DTMF" for short). In a preferred embodiment of the present invention, the transmission frame format of communication billing information is as follows: special frame header of call charge data + current call charge value. In another preferred embodiment of the present invention, the transmission frame format of communication billing information is as follows: special frame header of call charge data + current call charge value + recharge balance mark + recharge balance value. Those skilled in the field of the present invention will understand that other frame formats can be used to transmit communication charging information without departing from the essence and scope of the present invention.

In addition, it should be pointed out that when the network-side billing device 10 sends the communication billing information to the user terminal 20, the ring current signal is not required, and the user terminal 20 does not need to ring. The terminal can be flexibly set to set whether the terminal itself provides a prompt tone after detecting the call charge data.

Then enter step 200, after the user terminal 20 receives the data from the network side billing device 10, judge whether the data is communication billing information according to the value of the data frame header, if yes, then enter step 300, otherwise end this process. Of course, the user terminal 20 can enter other processes according to the type of received data, but this process for realizing communication charging information feedback is over.

In step 300, the user terminal 20 displays the received communication charging information. The user can know the exact cost of the call through the display of the user terminal 20 .

In a preferred embodiment of the present invention, the phone number 1234 calls the phone number 010XXXX, and the caller pays. After the call ends, the exchange sends the current call fee—2.00 yuan to the phone through the FSK signal. The data format is the special frame header 00000200 of call charge data. A, B, C, D, etc. can be used for the special frame header of the above call charge data. The exchange and the telephone terminal need to pre-agree on the content of the special frame header of the call charge data.

After the phone detects the special frame header of the call charge data, it fetches the call charge data, and it shows that the charge of this call is 2.00 yuan.

There is no ringing signal during the whole process, and the phone does not need to ring. The phone can be flexibly set to set whether the terminal itself provides a prompt tone after detecting a special frame header of the call charge data.

Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein, and without departing from the spirit and scope of the invention as defined by the appended claims.
