Description of the Invention: [Technical Field] The present invention relates to a communication system including N+α redundant configurations and a plurality of configuration management methods. [Prior Art] The next generation of high-speed wireless communication using, for example, Mobile WiMAX (Worldwide Interoperability for Microwave Access), which is used by the Internet Engineering Task F〇rce (Internet Engineering Task F〇rce) The grouping of standardized mobile IP (Intelnett pr〇t〇c〇l, Internet Protocol) technology is used to provide a mobile service to the mobile terminal.曰 Mobile WlMAX is supposed to provide services for large-scale users with many mobile terminals to support a wide range of wireless areas and wireless communications using mobile terminals that move at high speeds. Therefore, it is desirable to have a device configuration for a home station that is paired to the action < wiMAx, which is used to manage the location information of each of the slamming terminals, and to transfer the information to the line. The transmission of the location information volume of each of the many mobile terminals used by the large-scale users is managed by the pure transmission/connection (4) user (4) between the terminal and the network such as the Internet. ^The mobile WiMAX is a mobile terminal that provides high-speed mobile services. Therefore, the local network secret (4) and the ancient use of $ provide - continuous reliability of the high reliability. In addition, the local website route =L f Ϊ is used to flexibly increase the number of users and increase the transmission traffic. Purpose Many of the local website routers that are coupled to the mobile WiMAx are designed to transmit user data and utilize PC-based devices. As a high-reliability system that can continue to operate after the occurrence of Pt, it can be used to provide services for the system including the -ACT device and the corresponding SBY device for a redundant group. To replace the ACT i that has failed. The system of the redundant configuration of the system and the configuration of the n+i redundancy ((4)), and the charging of the system are disclosed in Japanese Laid-Open Patent Publication No. 2-5-1243. Ν+α, such as mobile _ Χ local website router is in the above-mentioned ft., when an ACT device is running, in a mobile Π > 2 闵 5 pairs will be dynamically logged in and deleted In order to make the conversation state change at any time, it is impossible for the SBY device to quickly take over the conversation state of the ACT device in which the failure occurred. In addition, when a failure occurs in any ACT device, an 8 Β γ ACT device (hereinafter referred to as a malfunction device) is used to provide a service dialogue to provide service. : = Ϊ Ϊ , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Connected - the problem, because the SBY device takes a long time = business, tender and long. In particular, if a communication system, such as the user, Bena, is set to use _κ communication between the device and the material transfer device, the SB γ device needs to be used for a long time. A large number of addresses and routing information can also provide dedicated hardware for the ACT 1 and SBY devices to share the 0 setting information and the dialog information, which leads to the cost of the communication system. For the service of transmitting a large amount of data, and the period of the configuration that requires an affordable configuration, the second website is connected to the local website router of WlMAX, knowing that the fBY device can be switched to the act device containing the dialog connection at high speed. The coffee does not increase the cost when the service interruption is minimized when the failure occurs. 200952399 [Summary of the Invention] In light of the above, the present invention (4) notifies the service interruption time and does not make it possible to minimize the purpose when the failure occurs, and the communication system according to the present invention. In order to achieve a user data transmission device for a, the communication system includes: a majority of the user data, the transmission is generated by a user to generate a pair of devices, and at least one is H 5 a redundant device comprising a plurality of alternatives that are continuously operated; - a database: each side of the 5H current device includes setting information for transmitting the user data transfer device; and Management information of each address and routing information. Second, the user data transmission device determines the information and indicates the dialogue state. All the devices are set up. - Port 2: Several configuration management The method is a plurality of methods in the communication system, and the method is used to use a value for each of the "f" users. The majority of the existing devices in operation, including the redundant storage of the replacement of the current device of the J F cleavage device, the lp address of the user data is sent to the lp address, and the data is not fixed. One of each of the active devices The conversation information of the state; in the redundant device towel, when the fault occurs in any of the current service towels, the user data is continuously transmitted based on the setting information and the dialogue information stored by the redundant device itself. An existing device of the fault has occurred, and the setting information and the dialog information correspond to an active device in which the fault has occurred. [Embodiment] Next, the present invention will be described with reference to the drawings. Fig. 1 is a view showing the present invention. A block diagram of a configuration embodiment of a communication system. As shown in FIG. 1, a communication system 1' of the present invention implements a local website router that is coupled to a mobile WiMAX, for example, including: N+1 user data.

Instead, the SBYF-only device can be used to quickly replace the ACT^ amount specified by the management device 3 to be two-dimensional. Therefore, the failure of the ACT^ can be quickly reduced. When the service is interrupted, the user service is provided, and the dialog information of the conversation can be provided without knowing that the failure has occurred.

After the startup, the six-way transmission to the SBY device is performed. Thus, even if the device is in a state of paralysis, the dialogue information in the SBY device does not coincide with the ACT response and the operation of the communication system in accordance with the present invention will be described with reference to FIG. 200952399. Figure 2 is a timing diagram showing an operational embodiment of the communication system shown in Figure 1. As shown in FIG. 2, when the communication system is activated, the management device 3 starts monitoring the state 2 of each of the N+1 user data transmission devices via the management unit 32, and then, via the system setting unit 31, the management device 3 The corresponding setting information is transmitted to each ACT device in sequence. In the process, the management device 3 also transmits the setting information of each ACT device to the SBY device, and the SBY device combines the ACT device with the corresponding setting information, and stores the result in the memory of the SBY device itself.

When the ACT device that starts the service receives the request to start the conversation from the user, it prepares a conversation to be used by the user (mobile terminal) and transmits the user profile of the user. When the ACT device receives the dialog update signal (location information update signal) from the enabler, it updates the dialog. When the parent prepares or updates the conversation, the ACT device transmits a notification to the SBY device. The device stores the conversation information that receives the device number from the ACT device and is related to the ACT device.

When preparing or updating the dialogue in the ACT device, the 8 Β device also stores the dialogue information of each ACT device and updates the dialogue information of each ACT device to make SBY. The device can quickly take over the conversations dictated by the faulty device. In this way, when a fault occurs, the service interruption time can be reduced to 'less' and the service can be provided without the user knowing that the fault has occurred. 'y also according to the present invention, it is possible to construct an inexpensive communication system including a PC (Personal Computer) based communication, and if a failure occurs in any ACT device, the SBY device can continue a communication service. Providing communication services, operators can reduce their equipment investment.
