Description

Internet call processing device in exchange system {APPARATUS FOR PROCESSING INTERNET CALL IN A SWITCHING SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a call separating apparatus of an electronic switching system, and more particularly, to an internet call processing apparatus in an exchange system for separating and processing a general call and an internet call.

In general, the types of calls required through a general telephone line include a general call requesting a call from a general subscriber to a general subscriber and an internet call requesting access to the Internet network through a modem.

FIG. 1 is a block diagram illustrating a general switch system including a plurality of Access Switching Subsystem (ASS) 110, an Interconnection Network Subsystem (INS) 120, and a Central Control Subsystem (CCS). Control subsystem) 130, router 140, and processes the general call and the Internet call through a modem.

When digit information is received from a predetermined subscriber, an access switching processor (ASP) of the ASS 110 requests number translation to the INS 120, and the INS 120 translates the received digit information to the number. When the result is notified to the ASS 110, the ASP of the ASS 110 determines the general call and the internet call based on the number translation result.

That is, the ASP of the ASS 110 corresponds to the corresponding ASS 110, i.e., the subscriber according to the call request, via the space (S) switch of the INS 120 if the translation result of the number in the INS 120 is a general call. A link is formed by ASS, and if the number translation result is an internet call, the link is connected to the Internet network 150 through a communication path provided by the router 140 through the space (S) switch of the INS 120.

Although the above call processing process refers to the processing of general calls and Internet calls made through a Public Switched Packet Data Network (PSTN) network, the call processing processes of general calls and Internet calls required through the ISDN network also refer to the above-described PSTN networks. It will be readily understood by those skilled in the art that the call processing process is performed in the same way.

On the other hand, the average use time of the Internet usually takes more than three times as much time as a normal phone use time.

Therefore, the conventional call processing scheme as described above, that is, the call processing scheme in which both the general call and the Internet call pass through the INS 120, is held in the case of an Internet call having an average usage time of 3 times or more than the general call. In other words, as the time until the subscriber hangs up the call becomes longer, the load of the INS 120 is increased and the resources of the general call are difficult to secure.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a communication path for an internet call during call processing in an exchange system, thereby preventing an increase in load on the INS. An internet call processing apparatus is provided.

In order to achieve the above object, the present invention provides a time slot link for time-division switching of an internet call input through a modem of a general telephone network (PSTN) and an internet call input through an integrated information communication network (ISDN), and the timeslot. A switch system for separating an internet call provided from a link and connecting the same to an internet network through a router, comprising: an internet call distribution means for distributing the time division switched input internet call; Speed conversion means for converting to a speed corresponding to a processing speed of an internet call provided by said internet call distribution means; Matching and maintenance control means for controlling matching and operational maintenance of the speed converted Internet call provided by the speed conversion means; Provides a control signal according to the type of Internet call currently input to the Internet call distribution means so that the Internet call distribution means can provide the input Internet call to the corresponding speed converting means, and manages state management for maintenance. A match exchange processor for providing a signal to the match and maintenance control means; Matching and maintenance control means for performing operation maintenance according to the state management control signal from the matching exchange processor and matching the Internet call provided by the speed conversion means to be connected to the Internet network and providing the same to the router; And signal transmitting means for providing status management control signals from the matched exchange processor to the matched and maintenance control means.

That is, in each of the nine boards, the Internet call provided by the distribution unit 214-1 is converted to the speed corresponding to the corresponding Internet processing speed, and provided to the matching and maintenance control unit 214-3. Information about each subscriber is collected and provided to the matching and maintenance control unit 214-3.

The matching and maintenance control unit 214-3 having a redundant redundancy structure performs operation maintenance of the Internet call separation device (IGU) and matching with the router 260. That is, the matching and maintenance control unit 214-3 provides the router 260 by processing the TCP / IP protocol so as to access the internet call, which is converted to the internet processing speed, so as to be connected to the internet network. If a state management control signal for maintenance of each component of the Internet call separation device (IGU) from the matching exchange processor (ASP) 213 provided through TD_Bus is provided from (214-4), the Internet call separation device ( Perform IGU) operational maintenance.

The router 260 connects to the Internet network by providing a communication path for the Internet call that is speed-converted from the matching and maintenance control unit 214-3 and provided by TCP / IP protocol processing.

Here, the Internet call separation device (IGU) is mounted on a plurality of matching exchange subsystems, that is, ASS_S, ASS_I, ASS_T, and ASS_V, respectively, to separately perform processing for each Internet call.

As described above, the present invention provides a separate communication path for each Internet call required in the exchange system, thereby increasing the load of the INS generated by the same processing of the general call and the Internet call in the exchange. It also prevents the congestion of the call volume by securing the resources of the general call and provides the effect of smoothly performing the maintenance of each line.
