Description of the invention (1) Field of the invention The present invention relates to providing services by telephone. BACKGROUND OF THE INVENTION With the advent of Computer Telephone Integration, various service providers are gradually providing free service numbers and using the Interactive Voice Response IVR system to process queries. Figure 1 shows a typical known Advanced Intelligent Network AIN for arranging a customer service inquiry route via a toll-free number. When dialing a toll-free service number, the call '1' is switched by a local central office switch (Locai Central Office Swhch) 11 to a Service Control Point (SCP) 12 shared by many service providers. The service control point 12 refers to the dialed number in a look-up list and processes the call based on the look-up list data. The lookup table will send back an actual number for the call to actually connect to a Remote Central Office Switch 14 via the public service telephone network PSTN 1 3. Most such call calls end in a call processing center (CaU Center) 15, which may provide some product support or sales services. Generally speaking, the call terminal 10 is provided with an Interactive Voice Response 16 in the form of an audio menu representing many different listed options. Users can select a desired option by pressing one or more buttons on their telephone keypad. With this method, preliminary processing of user queries can be automated, thereby saving personnel costs for service providers. -4-This paper size applies to China National Standard (CNS) A4 specification (210 X 297 public copy) --------------- IIII i I Order -------- -(Please read the dignity matters on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 420 9 1 7 ____B7__ V. Description of the invention (2) After accepting user inquiry, IVR ί 6 will call Control of the call is transferred from the parent to an Automatic Call Distribution Point (ACD) 17. ACD 17 distinguishes the user's query and then directs the call internally to the customer service representative best suited to handle the call query. If the customer service representative is busy, the query is added to a pending call queue to a group of customer service representatives, and any one of the group representatives is suitable to provide the requested service. When this happens, users are often placed, 'Please wait %% until you reach the _ line in the internal line of the appropriate customer service representative a. This will take a considerable amount of time, depending on the length of time such as Factors such as the number of users waiting for the same customer service representative, the number of service representatives qualified to handle the query, and the length of time each query takes. Response by interactive voice The average average time to initially process user queries is up to minutes, and users may then wait a few minutes before connecting to the correct destination. Obviously, as long as the user has to wait in a queue before his query is processed by the service provider, there will be an increase in connection cost proportional to the waiting time. But these, "waiting" costs are annoyingly billed at high rates equivalent to long-distance calls, and if these costs can be reduced, it will be a significant improvement for payers who are generally service providers . SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method and system for reducing the overall unit cost of a telephone call directed to a receiving terminal via an automatic call distribution system (ACD). This objective is achieved according to a specific embodiment of the present invention, the method of which is: (a) Shi Zhi an interactive sound response system (VR) in the user's area to apply the national standard (CNS) A4 specification through this paper standard (2) 0 X 297 Gongchu) -------------- Install --- (谙 Read the precautions on the back before writing this page) I-J.

Description of the invention (3) A low-rate ordinary telephone line receives a customer request, (b) will be from IVR The attention service request is directed to the ACD via a low-cost data communication line in order to maintain a call queue waiting for attention service in the ACD, (c) the ACD notifies the IVR when the request reaches the queue—a predetermined position, and (d) will The call is rerouted from the IVR to the ACD via a regular telephone line. On a more basic level, the idea of the present invention is to realize that any telephone call includes a warning or reminder request signal from the receiving end and constitutes a message to be transmitted Content media, and these Number and the media do not have the delivery path along the same path. Specifically, data communication networks such as the Internet can be used in parallel with ordinary telephone lines in order to arrange for the required signals that do not require high-quality communication lines to be delivered via the data communication network, and media that require high-quality communication lines Arrange delivery via regular phone line. In the present invention, the expression of this concept can be seen in step (b) to signal the receiving end, and only actual data is delivered to the receiving end in step (d). That is to say, “initially” the notification signal is delivered locally to the ACD via the data communication network, and the media is only delivered via the ordinary telephone network path when the receiving end indicates that it is ready (or near ready) to receive the media. During the period between the initial activation of the signal to the local IVR in step (b) and the transfer of the media to the ACD in step (d), the user is maintained in a state of 'waiting,' (〇n_h〇ld). However, the cost of maintaining the connection between the user and the receiving end is very low, because during this period of several minutes, the required signal is transmitted through a low-cost data communication network. In this respect, the present invention can be reduced to the following steps: -6- This paper size applies the Zhongguanjia Standard (CNS) A 丨 now ㈣ × view) * '^ ---- ---- Order · ---- I --- (谙 read the phonetic on the back?

Description of Invention (4) (a) Provide a telephone network with the public Parallel low-cost data communication lines, (b) identify the required signal and media parts used to alert the receiving end during a telephone call, and (c) separate the required signals and media parts through the data communication line and the telephone network. Cheaper route delivery. Preferably, the receiving end is a remote service provider. The service is provided and provided through a local low-cost or toll-free number. The connection between the Service Control Point and the service provider is generally high. Long-distance calls charged at rates. The present invention allows a service provider to request an alternative connection method via a data network (typically the Internet) for a pending service, while a normal connection using a telephone is still available. Since the cost of this link is borne by the service provider, the method of the present invention achieves immediate cost benefits for the service provider. However, the caller will eventually benefit because the connection cost from IVR to ACD will inevitably still be reflected in the service cost of the service provider. These costs can be further reduced by using a low-cost link between the caller and the IVR to play local commercials and subsidize phone revenue with their revenue. As such, due to IVR's proximity to the customer 'service call, the call is initially processed via a low cost local phone. Whether the cost is borne directly by the service provider or by the user, the user benefits as a result, because the service provider ’s cost of payment is inevitably anti-blocked to its rate. After that, once the call When the call is redirected to the service provider, the link is charged at a high rate corresponding to the distance that the current link of the Xi link extends.

Description of Invention (5) Make long-distance telephone calls can also be delivered at the unit cost of local calls. As is well known, the Internet Not suitable for instant voice communication due to its bandwidth limitation = This method is feasible when the caller does not need to have a voice conversation with the receiver 'like the situation during which the user waits for attention to the service. During this waiting period' the caller Not connected to the receiver, but only to the IVR Then when ordinary conversation needs to be maintained, the connection is made on an ordinary telephone line. Brief description of the diagram In order to understand the present invention and see how it is implemented in practice, it will now be described with reference to the drawings by way of non-limiting example only. Some preferred specific examples, among the drawings: Figure 1 is a block diagram showing the functionality of a typical prior art telephone system to pass service requests via a toll-free number; Figure 2 is a block diagram To functionally display a telephone system according to the present invention for transferring service requests via a toll-free number; and Figures 3a and 3b are flowcharts showing the main operational steps accompanying various configurations of the system shown in Figure 2 A better specific example details the print by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 2 shows a system 20 as a function. This system 20 is used to reduce a "calling end" composed of users 2U. The call distribution system (80: 0) 23 leads to the overall unit cost of a telephone call call to a call service processing center 22 (constituting, 'receiving end'.) The system 20 includes—via The local central office switch 25 is connected to the user's local interactive voice response system (IVR) 24. As is well known in the system, the local central office switch 25 allows the user to access one to convert the dialed toll-free telephone number into an actual The service standard of the number is based on the paper standard of CNS A4 (21〇χ 297) A7 420917 BL______ 5. Description of the invention (δ) Production point (SCP) 26, the actual number is automatically dialed so that The user's call is delivered to ACD 23 on PSTN 27 via a remote central office switch 28. PSTN 27 constitutes a "common telephone line" and allows the user's call to be treated as a normal telephone call at a normal rate. However, since the user 2 1 is in contact with the local IVR 24 at the beginning, even if the call call processing center 22 may be far away from the user 2 1 and needs to use `` mainline call '', the initial processing of the request is still a low rate "Local call" In parallel with PSTN 27, there is also an IP (Internet Protocol) data network 29 (such as the Internet). This data network 29 constitutes a local central office switch 25 Switch to "low cost data communication line" for local IVR 24. The IP data network 29 directs an attention service request from the local IVR 24 to the ACD 23 to maintain a call queue in the ACD 23 waiting for the attention service. The IP data network 29 further directs a call transfer request signal from the ACD 23 to the local IVR 24 when the request reaches a predetermined position in the queue. In response to the selective call transfer request signal, the local central office switch 25 re-routes the call from the local IVR 24 to the ACD 23 via the PSTN 27. The optional added function is to connect a remote IVR 3 0 to the ACD 23 to pass The IP data network 29 communicates with the local IVR 24. In this case, the local IVR 24 is connected to an Internet node location at the receiving end via the IP data network 29 at a low cost. Instead of providing traditional voice response at this time, a menu is downloaded from the location of the received Internet node for the user to choose the desired advanced service item. After the user has made the desired further service details, a link request message is sent to the call service via the remote IVR 30.

Description of Invention (7) Processing Center 22, and the "link request message" is queued until the desired further service details can be So far. Alternatively, the visual display menu may be converted into the IVR sound theme for the user 21. In both cases, the communication with the user 21 is a low-cost communication via the IP data network 29. 3a and 3b show the main operation steps of the cooperation system 20. Therefore, the user's call is delivered to the local IVR 24, and the local IVR 24 will direct an attention service request to the ACD 23 via the IP data network 29 to maintain a call queue for the attention service in the ACD 23. When the request arrives in the queue—predetermined location 'ACD 23 notifies IVR 24 and the call is rescheduled to be delivered from AVR 24 to ACD 23 at normal rates via the PSTN 27 route = In general, when received When the user requests service, the ACD 23 combines the call with the individual request and puts the user on hold. When the request is listed first in the queue, the ACD 23 transfers the call to the call processing center 22 and removes the request from the queue. So it is clear that before the user's request reaches the pre-arranged position in the ACD queue, the user is only charged at a low rate that matches the connection to the ιρ data network 29. These costs can themselves be subsidized by transmitting commercials from the local IVR 24 to the user 2 while waiting for the call call processing center 22 to connect. Although some specific examples have been described above, please note that there may be further variations without departing from the scope of the invention as defined in the appended patent application park. Specifically, please note that the present invention is based on the understanding that a low cost data communication network such as the Internet can be used with a normal telephone line so that a service request is received before it is received by a remote service provider.
