Description of the invention (l) Technical field of I.M. The present invention relates generally to the processing of telecommunication signals and more specifically to the path of Internet telephone arrangements. Method and device. BACKGROUND OF THE INVENTION As the demand for access to the Internet or online services grows, an increase in the proportion of pressure on telecommunications equipment occurs to support this demand for access. Users are typically received via one or more Internet service providers. Every Internet service provider is generally accessed by users using discrete local telephone numbers, which provide extensive convergence into a public switched telephone network. Access to Internet service providers is typically free local calls, where the local exchange and communication company does not benefit from the use of the phone. Internet service providers use custom subscriber code plans to connect to the end of the public switched telephone network. There are no restrictions on Internet access, the designation of Internet service provider phone numbers, or the location of Internet service providers. Internet traffic between users and Internet service providers is mainly to route routes on the existing public switched telephone network on the same trunks that carry audio, fax, and data calls. Traditional network engineering traffic guides do not take into account the long average hold time for this Internet call. Most telecommunications equipment is designed based on an average call hold time of 3 to 5 minutes. However, the average talk time for Internet calls is significantly longer. It is currently estimated that the Internet and similar services have increased the total average call hold time to more than 10 minutes. "This is expected to increase with continued Internet growth. The current end switch in the public switched telephone network is not constructed. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ----------- t ----- -.-------- 11 (Please read the notes on the back before filling out this page) 4 A7 B7 ___ ^ V. Description of Invention (2) Built to support extended access to the Internet. The increase in the average number of Internet calls puts a limit on the public switched telephone network, and Yingli to provide local users and their expected service quality. Public switched telephone networks are no longer able to provide effective ringbreaking services to their customers while meeting the growing needs of the Internet. Increasing the average call retention time will reduce the trunk's carrying capacity, and because these calls are free, the revenue per call will be reduced due to the increase in the content of each call. Although additional trunks can be set to support increased call hold time, this addition will increase trunk group costs and operating costs. Congestion within the public switched telephone network can occur when customers try to make a circle or try a circle call again. Customer dissatisfaction and increased service costs due to the consequences of service quality. Expensive and complex switch reconstructions will be needed to alleviate the congestion caused by Internet telephony on public switched telephone networks. Therefore, it wants to reduce the congestion of the public telephone exchange network caused by the long call holding time of the Internet phone. Invention of Cobalt From the foregoing, you will see that the technical need to avoid congestion in the public switched telephone network caused by the long call retention time of Internet phones has arisen. According to the present invention, a method and a device for arranging Internet telephone paths are provided, which actually eliminate or reduce the disadvantages and problems related to the common processing of Internet telephones. According to one embodiment of the present invention, there is provided A device for routing telephone routes, which includes a joint modem to be exchanged by public telephones.

Description of the Invention (3) Internet Thunder The analog signal of the speech is converted into a digital data format. An ATM grid adaptation unit converts digital data format into atm grids. A network interface transports the ATM cells to an Internet service provider on an ATM network separate from the public switched telephone network. The aTM cell used by Internet phones includes location information generated by the ATM location unit in conjunction with the signaling protocol of an SS-7 network to determine the appropriate destination for such Internet phones. The present invention provides a variety of technical benefits over conventional Internet telephony processing. For example, a technical advantage is the rerouting of the Internet telephone path outside the public switched telephone network. Another technical advantage is to avoid placing Internet calls on a public switched telephone network. Yet another technical advantage is the delivery of Internet calls to an Internet service provider in an asynchronous transfer mode grid format on an asynchronous transfer mode network. Other technical advantages are obvious to those skilled in the art from the following formula, description and patent application scope. Short description of the drawings In order to have a more complete understanding of the present invention and its advantages, the following description will now be made with reference to the drawings, wherein the same reference numerals represent the same parts, where: Figure 1 illustrates a block of a telecommunications switching network; Figure 2 illustrates a block itf | circle of an Internet telephone via a telecommunications switching network.

Invention Description (7) 142. The identification and redirection of the data call is borrowed from the signal transfer point 128 to SS7 The messaging protocol is implemented. The Internet routing element 124 is used to modify and transport data call traffic to the data exchange network 146. In order to alleviate the user side congestion at the source and end switch 116, the call destined for the information service provider 142 is identified to successfully divert the data call to leave the public switched telephone network 112. This identification processing is performed by the signal transfer point 128. During the normal call processing sequence, the line access switch 126 converts an analog POTS signal from the user 139 or 140 into a digital DSO signal and sends this signal to the source end switch 116 to start call processing. Call requests that cannot be connected locally will generate an SS7 message and be sent to signal transfer point 128. The call is completed when an SS7 message is sent back by signal transfer point 128 with an indication of the route arrangement. When the signal transfer point 128 determines that the call is placed at the information service provider 142 on its called party's address during its digital analysis process, its coordinating sequence of the initiating message is' this makes the source end switch 116 not connect to the call, The release matrix and release line access switch 116 are not connected to the call, and release the neutral line resources between the matrix and release line access switch 126 and the source terminal switch 116. The signal transfer point 128 guides the line access switch 126 to redirect the call from the source end switch 116 to the trunk resource to another resource (such as a dedicated ds0 / DS1 circuit or an internal joint modem connected to the ATM). Bypassing the public switched telephone network 112 », the data exchange network 146 then connects the resources between the line access switch 126 and the information service provider 142. The line access switch 126 continues to monitor the interruption of the user during the entire conversation t as would be done for any call. When the test user tree is broken, the 'line access switch 126 notifies the source end switch 116 so that the user line can be used for incoming and outgoing calls. The line access switch 126 is also accessible. 4e This paper size applies to the Chinese National Standard (CNS) A4 specification (210x297 mm) (please read the precautions on the back before filling this page)-Install i 丨! — 丨 Order! ---- 10 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (8) The signal switching point 128 is known, so that the dedicated DS0 / DS1 circuit or ATM modem connection can be disassembled and used for Other calls. If the line is not connected, the source ' signal transfer point 128 of the information service provider 142 notifies the source end switch 116 and the line access switch 126 to update its call status. All control information exchanges between the signal transfer point 128, the line access switch 126, and the source end switch 116 are performed using a standard signaling message (such as Q.931) on the standard interface. Although line-side redirection eases congestion directly at the source end switch 116 and indirectly at the repeater key network 120 and the terminating end switch 117, trunk side redirection is implemented to directly eliminate the repeater key network. 2 The trunk network in the end switch is crowded. Trunk side redirection is implemented at the source end switch 116 to adjust the congestion at the repeater key network 120, and trunk side redirection is also implemented at the repeater key network 120 to target the termination at the end Congestion treatment of 117. In order to successfully divert data calls from the trunk network of public switched telephone network 112, signal transfer point 128 identifies calls originating from user 16 or 18 and destined for information service provider 142. During the normal call processing sequence, the source end switch 116 detects the answering status of the user 16 or 18 and generates an SS7 message. The call request that cannot be connected locally is sent to the signal connection point 128. When an SS7 message is sent back from the signal transfer point to indicate the route arrangement, the call is completed. When the source end switch 116 detects that the caller has hung up and terminates the call, the call is terminated. When the signal transfer point 128 determines that the call is placed on the information service provider 142, it directs the source end switch 116 to The call is redirected to the Internet routing element 124. The Internet routing element 124 places the call on a dedicated DS0 / DS1 circuit or an internal joint number of papers connected to the ATM.
