To allow you to purchase goods or receive services,

The present invention relates to an "expanded toll shortened number system and its operation method" which extends the functions of a conventional toll-free short number system from a collect call-based terminal to a general wired / wireless telephone based on a collect call.

Technical background of the invention

With the development of communication technology, the demand for communication is expanding rapidly, and many service providers are competitively participating in the communication service market.

In a fiercely competitive telecommunications market, with various carriers participating and fiercely competing for their customers, the success is determined by who provides better quality telecommunications services.

However, from the current point of time when communication-based technology is secured, various communication services provided by each service provider have largely the same form in a large framework, and thus are not greatly differentiated by service providers.

On the other hand, customers who want to receive telecommunication services from telecommunications operators have evaluated the quality of their products in detail, with very much information obtained through the Internet when selecting telecommunication service products they want to use. Next, the final product is decided.

In addition, the selection of communication products by the customer directly results in the selection of the communication service provider due to the characteristics of the communication products.

In some cases, even the seemingly trivial problem from the carrier's point of view is that the customers who use the product are often very uncomfortable. do.

In addition, as already mentioned above, the communication products that customers decide directly lead to the choice of the service provider. Therefore, current service providers find the above customer inconveniences before other competitors and improve the problem. By providing service products competitively, the company is trying to realize a huge increase in sales by stimulating customers' minds.

As part of the effort to resolve the inconvenience of customers, one of the recently developed and widely distributed communication service products is a toll-based communication service (aka collect call service) that allows the recipient to bear the communication fee. It is a speed dial service system that enables fast and convenient communication by reducing the number of times a user can dial.

 Conventional Technology 1

In accordance with the change of the communication market as described above, the present applicant has developed and distributed various communication service technologies, and as one of such technologies, a "collect call based speed dial service system and a system shown in FIGS. The operating method "has been developed and filed (Application No. 10-2006-0026890).

The "collect call based speed dial number service system" constructs a separate speed dial server in the collect call service system that is being implemented in addition to the collect call switch of the exchange at the receiver side, and receives the speed dial service through this. By providing a shortcut number service to subscribers on the recipient side,

To subscribers of the speed dialing service on the receiver side, various contents products and services can be provided to customers quickly and inexpensively at their own expense to facilitate advertisement and promotion,

To the general subscribers (customers) using this, by using the speed dial number service, they can quickly and easily access the content products or services they want to use to purchase the contents products they want or receive the services. It is characteristic.

Problems of Conventional Technology 1

However, the conventional technique 1 is a speed dialing system based on a collect call, which is very convenient when the collect call function is set in a specific call-equipped telephone or a specific terminal equipped with a collect call platform. In addition, it is not possible to use in general wired / wireless telephones based on caller-borne communication systems such as home fixed telephones and personal mobile phones which are commonly used by many subscribers.

Therefore, although the conventional collect call based speed dialing service system and its operation method are convenient in use, the use of the service is limited to the terminal based on the collect call. The problem is that it is difficult to expand to wired and wireless telephones.

Conventional Technology 2

On the other hand, in the general wired and wireless telephones based on the caller-paying communication system, another technology capable of providing a toll-based service is developed and utilized as shown in FIGS. 3 and 4.

As shown in Fig. 3, when the caller makes a call request from the caller's wired / wireless telephone to the toll carrier exchange through the public telecommunications network, the toll carrier exchanger connects it to the receiver and authenticates the caller. You can make a call and then charge it after the call ends.

This service is a very convenient communication method that is very useful when the sender is inevitably unable to pay the communication fee due to various circumstances such as enlisted soldiers, teenagers, overseas students and overseas travelers. have.

Problems of Conventional Technology 2

However, when the caller wants to make a call, as shown in FIG. 4, the related art 2 first dials the toll network operator switch and then calls the caller according to the message sent from the toll network operator switch. After the user presses a button for confirming whether or not to make a toll call, the call can be made only after passing through the caller authentication process and the call acceptance process of the receiver.

In other words, the caller has to take the hassle of dialing a large number of times, as well as having to spend unnecessary time in an unpleasant mood for the caller authentication and receiver acceptance process.

In addition, in the receiver's position (member's position), which requires the receiver to call the phone at the expense of the receiver, as in the prior art 1, the above problem is a very fatal weakness. .

The present invention has been made to solve the above problems,

Interconnecting the receiver side switchboard of the toll carrier network provider providing a collect call service to a general wired / wireless telephone system on a conventional wired / wireless communication system and the conventional collect call based speed dialing service system.

In the general wired / wireless telephone (calling party), the communication can be performed by the speed dial number without the caller's authentication process or the receiver's acceptance process by the speed dial number.

To subscribers of the speed dialing service on the receiver side, various contents products and services can be provided quickly and inexpensively to all callers and subscribers of wired and wireless telephones at their own expense, so that they can perform advertisements and promotions smoothly.

For all general wired / wireless telephone subscribers using the sender's side, the collectible-based speed dial service is used by the receiver to access the receiver and to access the contents goods or services they want to use more quickly and easily. The purpose is to enable the purchase of goods or the provision of services.

The configuration of the present invention for achieving the above object will be described with reference to FIGS. 5 and 6.

5 is a schematic diagram of an extended toll shortened number system according to the present invention, and FIG. 6 is a schematic diagram to simplify the overall configuration by integrating a duplicated configuration among the expanded toll shortened number system according to the present invention. .

Characterized in that configured.

Although the public communication network 320 based on the collect call-based public communication network 130 and the caller-borne communication system is shown separately for convenience of description, it is actually a kind of communication network operated by the same communication service provider. .

In addition, the collect call-based receiver side terminal 210 is actually a group of recipient groups 200 together with a general wired / wireless telephone 220 that provides a toll-based service based on a caller-borne communication system. In addition, it is connected to the toll-free communication network operator switchboard 330 so as to be able to communicate with the caller-side wired / wireless telephone 310 that provides a toll-free service based on the caller burden system.

Nevertheless, this is separated and represented as the receiver side terminal 210, since these groups are members of the collect call based speed dialing service system according to the needs of the receiver, and thus are additionally provided with the service. To explain more clearly.

In addition, the speed dial number service system 170 is a comprehensive representation of the configuration having a speed dial number server, a DBMS, a speed dial number management program, etc., the detailed configuration is already described in the prior art 1 filed by the present applicant Since it is described in detail, the description is omitted.

Referring to Figures 7 to 9 the operation process of the present invention configured as described above is as follows.

First, in the present invention, the communication is performed in three ways as follows.

First is a communication method using a conventional collect call-based speed dial number service from the caller side wired and wireless terminal 110 to the receiver side wired and wireless terminal 210.

Second is a conventional toll-free communication method that extends from the caller side wired and wireless telephone 310 to the receiver side wired and wireless telephone 210,

Third is a communication method using an extended collect call based speed dial number service according to the present invention from the caller side wired / wireless telephone 310 to the receiver side wired / wireless terminal 210.

The first and second communication methods of the above three communication methods are communication methods that are already implemented in the prior art, and since the conventional technical configuration is applied as it is included in the configuration of the present invention, the present invention It is generally performed in the same way.

Therefore, in the present invention, a detailed description of the two types of communication process will be omitted.

The technical gist of the present invention is to provide an extended collect call based short number service, which is the third communication method.

In order to be able to make calls to the toll free call system using a speed dial number system in a general wired / wireless telephone based on a caller-borne communication system, the following conditions must first be established.

First, whether the call signal transmitted by the caller carrying the caller-side wired / wireless telephone 310 requests a conventional toll-free communication service (the second communication method) or an extension number based on the extended call call. A protocol in which the toll network operator switcher 330 can confirm whether to request a "service" (the third communication method) must be provided.

Second, whether the call signal of the caller side wired / wireless telephone 310 received through the toll-free telecommunications network operator switch 330 requests a conventional toll-free communication service (the second communication method) or " The receiver side exchange 140 should be able to confirm whether to request an extended collect call based speed dial number service "(the third communication method).

In order to enable this, based on the collect call-based communication unit 100 and the caller-paying communication system based on the extended call call "transmitted and received between the general wired and wireless telephone communication unit 200 to provide a toll-based service Uniformity must be maintained in code to recognize "shortcut number service".

7 illustrates a communication protocol prepared for this.

The protocol is not fixed and exemplifies matters to be determined by independent judgment of each carrier.

When communication is performed according to the above rules, the toll-based network operator exchange may first confirm that the signal is a toll-based communication service request by calling number (for example, one of 1682, 1633, 1677, etc.). There is,

Subsequent communication signals (e.g., #, *, or any other code) indicate that the specifics of the service are requesting a conventional toll-free communication service or an extended collect call-based shortcut number. Secondly, you can check whether the service is requested.

Next, a description will be given of a process of providing an extended collect call based shortcut number service, which is the third communication method according to the present invention.

First, the caller having the caller-side wired / wireless telephone 310 first selects and dials the telephone number of the toll communication service provider switch 330 that provides the toll service.

For example, 1682, 1633, 1677, and the like.

Subsequently, when the toll communication network operator exchange 330 is connected through the public communication network 320 and the ring tone falls, the caller immediately operates the caller-side wired / wireless telephone 310 to request an extended collect call-based speed dialing service ( Press *) and then dial a known speed dial number.

In this case, the button for requesting the shortened service is not specified as mentioned above, but is determined by the recipient service provider in advance. For example, it could be a # or * button, or it could be a specific numeric button.

This is only a matter of choice determined by the toll carrier, so that the toll exchange operator 330 can recognize this.

In this case, however, the signal must be selected differently from the conventional signal for requesting a toll communication service to avoid duplication.

When a call request based on the extended call number extension is extended, the toll-free telecommunications operator switchboard 330 transmits the calling party's telephone number to the authentication server 340 to request authentication.

If the authentication result of the authentication server 340 is a signal for requesting the extended call-based shortened number service, after calling the call-side receiver 140 of the collect-call and informed that the extended collect-call-based toll-free communication service, After that, the speed dial number is received and the progress of the communication is monitored.

If the received signal is not a signal for requesting an extended collect call based short-number service, it performs a function for providing a conventional toll-based service.

Meanwhile, the collect call-based receiver side exchange 140 receiving the shortcut number together with the signal for requesting the extended call-based short number service from the toll network operator switch 330 undergoes a synchronization process of the received signal. The signal is transmitted to the collect call exchanger 150.

The extended collect call based shortcut number service performed here is substantially the same as the conventional collect call based shortcut number service.

In other words, from now on, the conventional "collect call based shortcut number service" and the "extended collect call based shortcut number service" according to the present invention are not particularly distinguished and provide services through the same process.

However, in order to enable this, a signal (eg, a * signal) requesting an extended collect call based shortcut number service as described above must be matched with an existing collect call based shortcut number service request signal. There is a need.

If this cannot be matched due to inevitable circumstances, a separate protocol must be created to confirm that the extended collect call based shortcut number service is the same as the existing collect call based shortcut number service.

For example, in the existing collect call based speed dialing number service system, if the collect call based speed dialing service request signal is set to # and the signal requesting to provide a general collect call service is set to *, a toll network operator ( If the extended collect call based shortcut number service received from 330 is requested as *, the collect call exchanger 150 does not recognize this as an extended collect call based shortcut number service and recognizes it as a general collect call service. This is because an error occurs by recognizing the received shortcut number as the general telephone number of the receiver.

In the above, the general collect call service refers to the caller's side and converts the call to the general collect call method when the recipient is not registered as a member to receive the speed dial service in the conventional collect call based speed dial service system. By requesting the caller to enter all the telephone numbers of the receiver, and then simply to provide a communication service in a collect call method without a shortcut number, which has been disclosed in detail in the specification of the prior art published.

Subsequently, the collect call exchanger 150 receiving the collect call service request first recognizes the service request identifier, and then determines whether the recognized identifier is a speed dial service request identifier based on the collect call service.

If the identifier is not a shortcut number service identifier (for example, a signal other than *), the service is provided through a conventional collect call service providing process.

However, if the identifier is a speed dial number service identifier (eg, a * signal), the speed dial number server system 170 is requested to provide the subscriber's telephone number.

When the subscriber's telephone number request is received from the collect call exchanger 150, the speed dial server system 170 searches for a DBMS (not shown) therein, and inputs the receiver side terminal 210 of the subscriber in advance. The subscriber's information such as phone number and membership level is provided to the collect call exchanger 150.

Here, the information table on the membership grade and the like stored in the speed dial server system 170 is configured as shown in FIG. In the above table, the membership grade is a customer management grade assigned by the operator for each application of the service content or the charging condition differently according to the contract condition with the receiver, which is described in detail in the related art.

The collect call exchanger 150 receiving the subscriber's information such as the telephone number and membership level of the subscriber's receiver terminal from the speed dial server system 170 calls the receiver side wired / wireless telephone through the toll network operator exchange 330. After connecting the communication line,

Monitor the end of the call.

Subsequently, when the caller / receiver ends the call, the call information is transmitted to the billing system 160 together with the subscriber information.

After receiving the call information, the charging system 160 calculates the charge according to the provision of the speed dial number service, stores the charge in the account of the receiver, and then terminates the collect call based speed dial number service provision situation.

Subsequently, the toll-bearing network operator switchboard 330 that was monitoring this confirmed the final call termination, and then transmitted the call information to the charging system 350,

The billing system 350 receiving the call information calculates the charges for providing the toll-free communication service, stores the charges in the receiver's account, and then switches to the toll-free telecommunication network operator that provides the collect call service to the general wired or wireless telephone. Ends the provision of the speed dial service.

Through the above process, it is possible to perform communication with a collect call-based wired / wireless terminal from a general wired / wireless telephone that provides a toll-based service based on a caller-borne communication system.

In the above description, the system is divided into two types of service providers based on a "collect call based speed dialing number service provider" and a "payload network operator providing a toll paying service based on a caller paying communication system." On the other hand, it was configured to have a separate authentication server or billing system.

However, when providing this service by integrating "collect call based speed dial service provider" and "toll pay network service provider based on caller burden type communication system" Can be simplified by partially integrating

FIG. 6 illustrates an integrated form of a "collect call based speed dial number service provider" and a "payload network operator providing a toll service based on a caller-borne communication system." The authentication server or billing system of the "Toll Network Service Provider that provides toll-free service based on the caller-borne communication system" is integrated with the collect call-based authentication server or billing system to simplify the configuration of the whole system. Can be.

In case of integrating the system as above, the cumbersome procedure of "certifying toll-free telecommunications network provider which provides toll-free service based on caller-sponsored communication system" may be omitted. It is convenient.

According to the present invention configured as described above,

In general wired / wireless telephones which are not based on a collect call, when making a call to a receiver terminal of a collect call based speed dialing system, the caller is responsible for the call charge and the caller is provided with a speed dialing service. ,

To subscribers of the speed dialing service on the receiver side, various contents products and services can be provided to subscribers (customers) of wired / wireless telephones of "Toll-Free Network Operators that provide collect call service to general wired and wireless telephones on conventional wired and wireless communication systems." Provide them quickly and inexpensively, at their own expense, to facilitate advertising and promotion,

To the subscribers (customers) of wired / wireless telephones of the "toll-free telecommunications network providers providing collect call service to general wired / wireless telephones on a conventional wired / wireless communication system" using the speed dialing service at the expense of the receiver, Faster and easier access to content products or services has the effect of purchasing their desired content products or services.

That is, the service limited to the conventional collect call-based wired / wireless terminal has an effect of extending to a wired / wireless telephone of a "toll-free communication network provider providing a collect call service to a general wired / wireless telephone on a conventional wired / wireless communication system."

Accordingly, it is possible to expect the effect of increasing the sales of communication operators by improving the quality of communication services.
