Description

Communication signal management device of the TAM-EMS and controlling method therefore}

The present invention relates to a communication signal management device and a control method of the TAM-EMS, in particular, using a certain port number and the unique number of the TAM-DSLAM equipment when transmitting and receiving data in the TAM-EMS operating management of a number of TAM-DSLAM equipment The present invention relates to a communication signal management apparatus for TAM-EMS and its control method.

In general, Asymmetric Digital Subscriber Line (ADSL) systems are designed to provide high-speed digital services such as high-speed Internet and online access without interfering with analog telephone service (POTS) on existing twisted pair copper networks. Refers to a service system provided to telephone subscribers such as telecommuting and VOD (VIDIO ON DEMEND). Therefore, such an ADSL system has a characteristic of downloading a large file containing graphics from a medium such as the Internet. In such an ADSL system, a communication signal is transmitted and received through a plurality of subscriber terminals and a communication pair. The DSLAM (xDSL Access Multiplexer) system and the DSLAM system are typically used by having an ATM switch connected to a medium such as a service medium, for example, the Internet or a communication server, through an optical cable.

In particular, such a DSLAM system provides a service in the form of a recent TAM (Total Access Module) as shown in FIG. 1, which is a voice and data integrated service by accepting PSTN / ISDN / XDSL subscribers as LOCAL and REMOTE. Aim to provide. Here, the LOCAL subscriber is accommodated in the TAM and provides a voice service with the switch subscriber (PSTN / ISDN) through interworking with the switch (LE) using E1 / T1 matching. On the other hand, the REMOTE subscriber is accommodated in RAM (REMOTE ACCESS MODULE) and uses the E1 / T1 / DS-3 / -STM-1 matching to directly connect with the TAM or through TAM via an ATM network. Provide voice service with subscribers and exchange subscribers. In addition, the TAM TAM and RAM through the direct linkage of the data traffic of the TAM and RAM subscribers with NAS / RAS using E1 / T1 / DS-3 / STM-1 matching or NAS / RAS via the ATM network Provides a data call service to the subscriber, wherein the plurality of TAM-DSLAM equipment receives the operation instruction from the TAM-EMS and provides a service.

Then, referring to Figure 2 of the communication management device of the conventional TAM-EMS as described above, the EMS 70 for managing a plurality of TAM equipment by outputting the operator's command in the SNMP method, the command of the EMS 70 According to the TAM-EMS unit 71 and the TAM-EMS unit 71 to write an operation command including the individual port number and the individual IP address to select the corresponding device using the TCP / IP protocol according to the IP packet, 71 And a plurality of TAM-DSLAM units 72A-N and TAM-DSLAM units 72A-N, which are connected to each other by TCP / IP communication and process voice / data traffic for PSTN / ISDN subscribers and XDSL subscribers. It is composed of a plurality of TAM-RAM units 73A-N which are connected to the TAM-EMS unit 71 remotely through a TCP / IP communication method and process voice / data traffic for PSTN / ISDN subscribers and XDSL subscribers. .

On the other hand, referring to the operation of the communication management apparatus of the conventional TAM-EMS as described above, first, a plurality of TAM-DSLAM unit 72A-N is connected to the switch (LE) using the set function, for example, E1 / T1 matching. It provides local subscribers with voice service with PSTN / ISDN. On the other hand, the remotely installed TAM-RAM unit 73A-N is directly interworked with the TAM-DSLAM unit 72A-N or via an ATM network using E1 / T1 / DS-3 / -STM-1 matching. In conjunction with the TAM-DSLAM unit 72A-N, the remote subscriber provides voice or text services to TAM subscribers and exchange subscribers.

At this time, when the operator of the TAM-EMS unit 71 inputs the necessary command to the TAM-EMS unit 71 through the EMS 70, the TAM-EMS unit 71 is an SNMP protocol method from the EMS 70 Analyze the network management message, and transmit it to TAM-DSLAM unit 72A-N or TAM-RAM unit 73A-N to collect or perform the requirements defined in SNMP. In this case, the TAM-EMS unit 71 communicates with the TAM-DSLAM unit 72A-N or the TAM-RAM unit 73A-N through the TCP / IP protocol. In order to distinguish which TAM-DSLAM device is for, it is sent with the promised individual port number and individual IP address.

However, the communication management apparatus of the conventional TAM-EMS as described above must use individual port numbers and individual IP addresses to identify which device the TAM-EMS unit should transmit and receive from among several TAM-DSLAM devices connected to it. At this time, when other equipment is used arbitrarily or new TAM-DSLAM equipment is added, a significant restriction was placed on additional port allocation due to the limit of the number of ports. Also, the TAM-EMS unit communicates with TAM-DSLAM. Not only do you have to memorize the port and IP address used for the system, but also the TAM-DSLAM aspect has caused a problem that the operator has to set the port number that the operator pre-designates for each device in advance.

Accordingly, the present invention has been invented to solve the above conventional problems, and it is not necessary to use a plurality of individual port numbers and IP addresses for TCP / IP communication, thereby reducing the resource waste of TAM-EMS. It is an object of the present invention to provide a TAM-EMS communication signal management apparatus and a control method thereof.

Another object of the present invention is to use a simplified constant port number and the unique number of the TAM-DSLAM device without the need to use a complicated port number and IP address in TCP / IP communication between the TAM-DSLAM device and the TAM-EMS The present invention provides a TAM-EMS communication signal management device and a method of controlling the same, thereby significantly improving the communication processing speed of the TAM-EMS.

The present invention for achieving the above object is an EMS for managing a plurality of TAM equipment by outputting the operator's command in the SNMP method, and using the TCP / IP protocol according to the command of the EMS header of the corresponding DSLAM equipment A TAM-EMS unit for creating an operation command including a unique IP address and a single port number promised and outputting the IP packet, and a port promised with its own IP in an IP header transmitted from the TAM-EMS unit. In the IP header transmitted to the TAM-EMS unit in the TCP / IP communication method through a plurality of TAM-DSLAM unit for analyzing the number and processing the command when the IP is confirmed, and the TAM-DSLAM unit. It provides a TAM-EMS communication signal management device composed of a plurality of TAM-RAM units that analyzes its own IP and one promised port number and processes the command when its IP is verified.

Another feature of the present invention is the TAM-EMS unit when the command is set from the EMS message containing the unique IP to create and send a message containing a unique IP number of the DSLAM device to receive the message to the IP header and one port number promised A unique IP verification step for each DSLAM device to verify that its own IP is included in the IP header of the message created by the TAM-EMS unit after the creation step and the message creation step including the unique IP, and the unique IP confirmation step If each DSLAM device confirms that its own IP is included in the IP header of the message created by the TAM-EMS part, the corresponding DSLAM device that requested the response performs the command requested by the EMS and then sends the result. Control method of TAM-EMS communication signal management device comprising a DSLAM response message transmission step of transmitting to the TAM-EMS unit the response signal containing the same IP header signal created during To provide.

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

As shown in FIG. 2, the apparatus of the present invention outputs an operator's command by using an SNMP method to manage a plurality of TAM devices, and uses an TCP / IP protocol according to the command of the EMS. A TAM-EMS unit 2 for generating an operation packet including a unique IP address of a corresponding DSLAM device and one port number promised in a header and outputting the IP packet, and the IP transmitted from the TAM-EMS unit 2. A plurality of TAM-DSLAM units 3 for processing voice / Data traffic for PSTN / ISDN subscribers and XDSL subscribers by analyzing their own IP and one port number promised in the header, and the TAM-DSLAM unit ( 3) Analyzing one's own IP and one port number promised by the IP header transmitted remotely to the TAM-EMS unit (2) through TCP / IP communication method to PSTN / ISDN subscriber and XDSL subscriber. It consists of a plurality of TAM-RAM units 4 for processing voice / Data traffic.

Here, the inside of the plurality of TAM-DSLAM unit 3 and the plurality of TAM-RAM unit 4, the main processor (5A, 5B) and DSLAM equipment (6A) under the function control of the main processor (5A, 5B) , 6B).

Next, the control method of the present invention as described above will be described.

The method of the present invention proceeds to the DSLAM general function execution step (S2) in the initial state (S1) as shown in Figure 4 to execute the general function of the TAM-DSLAM.

That is, the main processor 5A of the plurality of TAM-DSLAM units 3 provides voice services to the local subscribers through the switching function (PSTN / ISDN) to the local subscribers through interworking with the switch LEs using the set functions, for example, E1 / T1 matching. To provide. On the other hand, the main processor 5B of the remote TAM-RAM unit 4 is directly interworked with the TAM-DSLAM unit 3 by using E1 / T1 / DS-3 / -STM-1 matching or ATM network. It provides voice or text service to TAM subscribers and exchange subscribers to remote subscribers through interworking with TAM-DSLAM unit 3 via.

On the other hand, after the DSLAM general function execution step (S2) proceeds to the EMS command setting determination step (S3) to determine whether the command is currently set from the EMS. At this time, if the command is not set from the current EMS as a result of the determination during the EMS command setting determination step S3, the process returns to the previous step S2 and repeats the loop.

However, as a result of the determination during the EMS command setting determination step (S3), if the current command is set from the EMS, the process proceeds to the message creation step including the unique IP (S4), where the TAM-EMS unit transmits the message to the IP header. Create and send a message containing the number and the one port number promised. After the message creation step (S4) including the unique IP, the process proceeds to the unique IP determination step (S5), and each DSLAM device determines whether its own IP is included in the IP header of the message created by the TAM-EMS unit. . At this time, if the unique IP is not included in the IP header of the message generated by the TAM-EMS unit as a result of the determination by the DSLAM devices during the unique IP determination step (S5), the process proceeds to the end step.

However, if the unique IP is included in the IP header of the message created by the TAM-EMS unit, the DSLAM response message transmission step (S6) is performed. The DSLAM device that requested the response performs the command requested by the EMS and sends the result to the TAM-EMS unit with the response signal containing the same IP header signal created at the time of transmission.

In other words, there are two methods of communication between TAM-DSLAM and TAM-EMS, which are based on ATM using STM-1 optical fiber and transmitted via IP network connected to LAN port.

First, when communicating through the STM-1 optical fiber, since the TAM-DSLAM and the TAM-EMS are connected according to ATM PVC connection information preset for communication, the TAM-EMS receives pre-stored PVC information when receiving a command. It reads and sets to the corresponding VPI / VCI value and transmits.

On the other hand, when communicating over the IP network using the TCP / IP protocol in the above process, the IP address and port number of the destination is required, and an application process for transmitting a message and an application for receiving are required. At this time, in the case of an application process for transmitting the message, a socket for TCP / IP communication is created and sent with a transmission port number promised with the destination IP only when there is a message to be transmitted. In addition, since the application process receiving the message does not know when to receive a message, it is necessary to open a socket created with its own IP and a designated receiving port number, and always wait for a message to be received in a waiting state.

Therefore, in the conventional apparatus, the TAM-EMS unit 2 waits for receiving an incoming message by using a different port number for each connected TAM-DSLAM, and thus there exists an application process for each TAM-DSLAM. However, if the same port number is the same as the present invention, only one receiving application process is sufficient.

That is, when the operator of the TAM-EMS unit 2 inputs the necessary command to the TAM-EMS unit 2 through the EMS 1, the TAM-EMS unit 2 is an SNMP protocol scheme from the EMS 1. TAM-DSLAM part by creating a message including the unique IP number of the DSLAM device to receive the message to the IP header and the one port number promised to collect or perform the requirements defined in SNMP by analyzing the network management message. (3) and TAM-RAM section 4, respectively.

Then, the main processors 5A and 5B of the TAM-DSLAM unit 3 or the TAM-RAM unit 4 include their own IP in the IP header of the message created by the TAM-EMS unit 2. Check it. At this time, when it is confirmed that any one of the main processor (5A, 5B) of the TAM-DSLAM unit 3 or the TAM-RAM unit 4 has its own IP, the TAM-DSLAM unit 3 or The corresponding main processor 5A, 5B of the TAM-RAM section 4 runs one application process, executes the command requested by the EMS through the corresponding DSLAM device 6A, 6B, which is required to respond, and then outputs the result. The response signal including the same IP header signal generated at the time of transmission is transmitted to the TAM-EMS unit 2.

Therefore, according to the present invention, the TAM-EMS manages a plurality of TAM-DSLAM units or TAM-RAM units, but since they all use only one port number, the TAM-EMS is different from the conventional TAM-DSLAM unit or TAM-RAM unit. It is not necessary to secure a separate storage space for each port number allocated to each device.

As described above, the present invention processes a plurality of TAM-DSLAM devices by using a specific port number and a unique number of the TAM-DSLAM device when transmitting and receiving data in TAM-EMS that manages a plurality of TAM-DSLAM devices. There is no need to use individual port number and IP address, which has the advantage of reducing resource waste of TAM-EMS.

In addition, according to the present invention, a simplified schedule port number and unique number of the TAM-DSLAM device without the need to use a complicated port number and IP address when TCP / IP communication between the TAM-DSLAM device and the TAM-EMS Therefore, the communication processing speed of the TAM-EMS is also significantly improved.
