The present invention relates to internet traffic processing in a switchboard, and more particularly, when an ordinary subscriber or an ISDN subscriber accesses an internet connection in a telephone network, the switch is configured to process the internet traffic without occupying a switch resource and a relay line. It is about.

In general, a dial-up connection method in a public communication network includes a serial line interface protocol (SLIP) or a point-to-point protocol (PPP) using an analog modem, and an Internet service provider (SLIP or PPP method). Internet service is provided by converting Internet service or modem subscriber's Internet path through IPS (Information Communication Processing System) to packet exchange through Modem Pool of ISP;

Alternatively, an Internet network access service is performed using an integrated service digital network (ISDN) subscriber using a corresponding SLIP or PPP scheme. As shown in FIG. 1, a schematic conventional internet service structure is provided using a personal computer (PC). When using the Internet service at home, the route is first established to the local exchanges (10 to 10-N) to which the user belongs, and then connected to the Internet network through the local exchanges (10 to 10-N). The route is routed to the local exchange 30 to which the Internet service provider (ISP) 40 which enables it is connected.

In the local exchange 10 to 10-N, the apparatus for processing Internet traffic includes a subscriber matching unit 11 for access processing of an analog subscriber and an ISDN digital subscriber as shown in FIG. A time division switch unit 12 and 14 for accommodating the ISDM digital subscribers, time slot exchange, home-seat function, and relay line matching, and a space division switch unit 13 for performing a space division exchange function and a path connection and disconnection function of a call; And a relay line matching unit 15 for connecting with an Internet service provider through an analog modem subscriber through a circuit-switched network, and for separating the Internet traffic and exchanging it in a packet-switched manner to match with an intermediary of an internet network connection.

The Internet service provider 40 allocates an IP address to the modem pool 41 performing the PPP function of the analog subscriber, the IP routing unit 42 providing the Internet information, and the ISDN digital subscriber, and performs other authentication functions. A PPP function unit 43 is provided.

Briefly looking at the Internet traffic processing method in the conventional exchange, as described above, when the subscriber makes an Internet service request, it is input through the analog and digital subscriber matching unit 11 in the local exchange 10, the called party number When the translation finds out that the current user will use the Internet service, the local exchange 10 will route to the destination local exchange 30 that is connected to the Internet service provider 40.

At this time, the originating / receiving local exchange 10 divides the space with the time division switch unit 11 and 14 in the local exchange 10 in order to set a route for a call input to a subscriber and set a route for interworking with the Internet service provider 40. It occupies all the time slots in the switch 13.

As described above, in the conventional exchange, the Internet traffic processing occupies both the time division switch portion and the time slot in the space division switch portion, which are the switch resources in the exchange, due to the long occupancy of the Internet traffic. Relay line congestion occurs due to call blocking and traffic increase.

The present invention has been made in view of the above-described problems, and separates voice traffic and Internet traffic inside a switch, processes the call, and processes the corresponding Internet traffic to protect the voice telephone network due to long time occupancy of the Internet call. It aims to reduce the load of the public network due to the increase of the number of Internet subscribers and to provide the high-speed Internet backbone network and matching Internet service through the public network switching system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the switch according to the embodiment of the present invention, the Internet traffic processing apparatus includes a switch performing a PPP termination function, an IP address allocation function, an FR network or ATM network matching function, and a PPP frame processing function as shown in FIG. 100 is connected to the Internet network 200 or the public data network (300).

The exchanger 100 includes an analog subscriber matching unit 110, a time division switch unit 120, a data processing unit 140, a digital subscriber matching unit 150, a space division switch unit 160, and a data switch. A unit 170 and an Internet service provider (ISP) 160 are provided.

The time division switch unit 120 separately allocates timeslots according to voice traffic and Internet traffic.

The analog matching unit 110 accommodates analog general subscribers and modem subscribers and matches the time division switch unit 120 with a sub-highway (SHW).

The data processor 140 converts a PPP frame generated when using the Internet into a protocol for internal communication and performs a function of multiplexing / demultiplexing.

The modem pool 130 converts the data applied from the time division switch unit 120 into a PPP frame form and transmits and receives data to and from the data processor 140 and the subhighway.

The digital subscriber matching unit 150 accommodates digital subscribers.

The space division switch unit 160 allocates a link to data applied from the time division switch unit 120.

The data switch unit 170 performs a function of interconnecting the Internet PPP frame converted by the switch internal protocol.

The FR / ATM matching unit 190 serves to match an FR network or an ATM network to be used as an IP network.

The operation of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, briefly, in the exchange 100, the voice traffic of the analog subscriber / digital subscriber is separated from the path of the Internet traffic, and in the case of the voice traffic, the analog subscriber matching unit 110 is matched, and the time division switch unit 120 is used. And the path through the space division switch unit 160, and in the case of Internet traffic, the analog subscriber and digital subscriber matching units 110 and 150 are matched, and the data processing unit 140 is routed through the U-link. Through 120 is a path through the data switch unit 170.

In this way, when the Internet traffic increases in the exchange due to the increase in the use of the Internet, it does not affect the voice traffic, thereby reducing the network congestion caused by the Internet traffic, and occupies the switch resources and the relay line in the switch 100. Internet service without

Then, looking at the process of processing the Internet traffic generated from the analog subscriber, when the Internet service request from the analog subscriber, first, it is found that the Internet service request by the translation of the called party number. At this time, the modem call is terminated in the modem pool 120 through the time division switch unit 150 using the subhighway through the analog subscriber matching unit 110 through the Internet traffic.

The PPP frame generated after the modem call is terminated in the modem pool 120 is also input to the data processor 130 through the subhighway.

Accordingly, the data processing unit 130 converts the PPP frame input from the modem pool 130 into an internal protocol of the exchange and routes it through the U-link.

At this time, the data processing unit 130 does not affect the quality of the voice call since the Internet traffic is no longer used as the switch resource of the exchange allocated to the voice call from the moment the Internet traffic is routed through the U-link.

Thus, the Internet traffic routed through the U-link in the data processing unit 130 is routed in the data switch unit 170 through the space division switch unit 160, and the Internet service provider (in the data switch unit 170). The path is set to ISP 180 and is input to Internet service provider 180.

Accordingly, the PPP is terminated in the Internet service provider 180 and transmitted through the FR / ATM, which is an IP network matching device, to the Internet network or to the public data network.

On the other hand, when processing the Internet traffic generated from the digital subscriber, if the Internet service request from the digital subscriber, first find out that the Internet service request by translation of the called party number, the Internet traffic through the digital subscriber matching unit 150 The subhighway is input to the data processor 130 through the time division switch unit 120.

At this time, the digital subscriber matching unit 150 terminates the ISDN LAPD (Link Access Procedure On D-Channel), and the PPP frame input to the ISDN B / D channel is routed to the data processing unit 140.

Thus, the data processing unit 140 converts the input PPP frame into an internal protocol of the exchanger and routes it through the U-link.

From this time, i.e., from the moment the Internet traffic is routed through the U-link, the Internet traffic no longer uses the switch resources of the exchange assigned to the voice call and thus does not affect the quality of the voice call.

Then, the Internet traffic routed through the U-link in the data processing unit 140 is routed in the data switch unit 170 through the space division switch unit 160, and the Internet service provider 180 in the data switch unit 170. The path is set and input to the Internet service provider 180.

Accordingly, the PPP is terminated in the Internet service provider 180 and transmitted through the FR / ATM, which is an IP network matching device, to the Internet network or to the public data network.

As described above, the present invention separates voice traffic and Internet traffic inside a switch and processes the call, and processes the packet traffic to protect the voice telephone network due to long time occupancy of the Internet call, and reduces the load of the public network due to the increase of Internet subscribers. High speed internet service can be provided via public network switching system.

As described above, the present invention protects the voice telephone network due to long time occupancy of the Internet call by separating the voice traffic and the Internet traffic inside the exchange and processing the call, and processing the corresponding Internet traffic from the circuit transmission method to the packet transmission method. It can reduce the load of the public network according to the increase of the number of internet subscribers and provide the high speed internet service through the public network switching system.
