The present invention relates to a premium VoIP traffic classification apparatus and method for transmitting to a guaranteed NGN network.

The premium VoIP traffic refers to a VoIP packet transmitted from a subscriber station registered to a specific service (called a premium service in the present invention). It is a service that transmits VoIP packet through NGN network.

In general, a voice is conventionally transmitted through a PSTN-Public Switched Telephony Network, and data is transmitted through a data communication network (IP-Internet).

However, VoIP technology has emerged for the purpose of delivering voice through not only voice network but also data communication network due to the advancement of user desire and technology. The architecture of VoIP allows the gatekeeper to manage and control communications with the Internet in a local area network (LAN) or computer and telephony integration (CTI) environment. Interworking or management with the network is to go through the gateway (gateway).

The ultimate goal of VoIP is to achieve the same level of voice quality as a regular phone, but the reality is that it is not easy to achieve the desired sound quality due to transmission delay and packet loss issues caused by bandwidth overload.

Therefore, the VoIP service in the future will provide more stable and high quality VoIP service through the NGN network that is currently being introduced by carriers. Therefore, VoIP traffic is transferred from the existing Internet subscriber network to the next generation network to connect VoIP subscribers to this next generation network. It must be acceptable. To this end, it is necessary to filter VoIP traffic from subscriber aggregation Ethernet switch of subscriber network and to switch to NGN network.

For this filtering, the filtering conditions of VoIP subscriber traffic must be set in advance in the subscriber aggregation Ethernet switch of the subscriber network. If the number of subscribers is large, the filtering conditions of the subscriber aggregation Ethernet switch must be set. There is a problem with its performance.

The present invention has been made to solve the above-described problems, and an object thereof is to filter and classify VoIP packets corresponding to a premier service without affecting the performance of the existing Internet service.

Hereinafter, an apparatus and method for classifying premium VoIP traffic according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a premium VoIP traffic classification apparatus and VoIP phone according to an embodiment of the present invention.

As shown in FIG. 1, the premium VoIP traffic classification apparatus according to an embodiment of the present invention is an Internet subscriber aggregation Ethernet switch 100. The Ethernet switch 100 of the present invention includes a status detector 110, a terminal register 120, a filtering configuration setter 130, a selective packet transmitter 140, the VoIP phone 200 and the computer 300 Performs a path switching operation on the packet transmitted in the network.

First, the VoIP telephone 200 applied to the present invention will be described first, and the apparatus 100 of the present invention will be described.

The VoIP phone 200 of the present invention includes a hookoff information detector 210, a hook-on information detector 220, and a packet generator 130. The hook-off information detector 210 detects the physical state of the hook-off of the VoIP phone 200 and outputs it as an electrical signal, similar to a general plain old telephone service (POTS) phone. 220 detects a physical state of a hook on of the VoIP phone 200 and outputs it as an electrical signal like a general POTS phone. In addition, the packet generator 130 performs an IP packet on the status information of the VoIP phone 200 output from the hookoff information detector 210 or the hook-on information detector 220 and the MAC (Media Access Control) address of the VoIP phone 200. And the dynamic traffic is transmitted to the Ethernet switch 100.

However, there is no hook on / off information in the VoIP packet transmitted from the computer 300.

Next, the dynamic traffic classification Ethernet switch 100 according to an embodiment of the present invention will be described. The state detector 110 determines the current state of the connected VoIP phone 200 and determines the state of the VoIP phone 200 by the state information included in the packet received from the packet generator 230.                     

The terminal registrar 120 stores a mapping table for the premium service subscriber terminal (ie, the VoIP telephone) and confirms to the status detector 110 whether the originating VoIP telephone of the received packet is the premium subscriber. In the mapping table, source IP addresses and MAC addresses of the corresponding VoIP phones are stored as mapping information.

The filtering configuration setter 130 is notified of the status information from the status detector 110, and automatically sets or deletes the MAC address filtering condition of the VoIP phone according to the hook-on or hook-off status.

The selective packet transmitter 140 selects only packets having MAC addresses corresponding to MAC address filtering conditions set by the filtering configuration setter 130 and switches them to the NGN network.

Hereinafter, with reference to Figure 2 will be described the operation of the premium VoIP traffic classification apparatus according to an embodiment of the present invention.

2 is a flowchart illustrating a premium VoIP traffic classification method according to an embodiment of the present invention. As shown in FIG. 2, the state detector 110 receives a VoIP packet transmitted from the computer 300 or the VoIP phone 200 (S201).

Upon receiving the VoIP packet, the status detector 110 checks the source IP address and the MAC address included in the VoIP packet, and then requests the terminal register 120 whether the terminal having the verified source IP and MAC address is registered (S202). ).

Accordingly, the terminal register 120 is applied to the mapping table that stores the MAC address and / or source IP received from the status detector 110 to determine the registration of the terminal and notifies the status detector 110. Then, the state detector 110 checks the registration result received from the terminal register 120 (S203), and if the terminal is not registered, transmits the VoIP packet to the Internet through the selective packet transmitter 140 and registers it. If the terminal is configured to provide hook-up or off information included in the VoIP packet to the filtering configuration setter 130.

When the hook-off information is included in the VoIP packet (S204), the filtering configuration setter 130 sets the filtering condition using the MAC address provided from the status detector 110 (S205).

The filtering condition is a condition for filtering only VoIP packets (i.e., premium VoIP packets) to be transmitted to the NGN network among the VoIP packets received by the state detector 110. The terminal transmitting the MAC address, IP address or other VoIP packets It consists of one or more of the information to identify. Preferably the filtering condition is a MAC address. When the filtering condition is set, the state detector 110 transmits the packet to the NGN network (S210).

If the hook-on information is included in the VoIP packet (S206), the filtering configuration setter 130 deletes the filtering condition corresponding to the MAC information provided from the state detector 110 (S211). As described above, since the filtering condition for the MAC address is automatically configured and deleted due to the operation of the filtering configuration setter, the present invention may be said to perform a dynamic filtering condition setting operation for the MAC address.                     

On the other hand, for a predetermined time until the VoIP phone 200 is hooked off and hooked on, the VoIP packet not including the hook on / off information is received by the status detector 110, and the VoIP packet is subject to the pre-filtering condition. If it compares and matches, it is transmitted to the NGN network (S207, S208, S210).

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

The present invention enables the filtering of VoIP packets more quickly without affecting the performance of the existing Internet service by using the MAC address of the layer 2 in the dynamic filtering condition, so that the subscribers of the premium VoIP service have a stable and high quality through the NGN network. There is an effect of providing guaranteed voice communication.
