Description

  The present invention relates to a DSL mode management system, a management server, a DSL mode management method used therefor, and a program thereof, and more particularly to a parameter setting method of an optimum method among various DSL methods for a DSL (Digital Subscriber Line) line.

  Various DSL methods include various current standards related to xDSL, such as ITU-T (International Telecommunication Union, Telecommunication Standardization Sector). 992.2 (VDSL: Very high data Subscriber Line), ITU-T G. 992.1 Quad, ITU-TG 992.1 Annex-I, ITU-T G. 992.5 (ADSL +: Asymmetric Digital Subscriber Line plus), ITU-TG 992.3 (ADSL bis), ITU-TG 992.1 Annex-C DBM (dual bitmap), ITU-TG 992.1 Annex-C FBM-sOL [FEND (far-end crossover) bitmap overlapped overlap] / EFBM-sOL (extended FBM-sOL), and DSL method determined by xDSL-related standards to be defined in the future. Hereinafter, these methods are referred to as a DSL mode.

  In recent years, the ADSL market has grown rapidly as a DSL system. At the same time, there is an increasing desire from end users to use a lower-cost, higher-rate broadband network environment.

  The xDSL technology has made rapid progress to answer this user's desire, and the rate provided by the ADSL service is increasing every few months.

  In the conventional DSL system described above, the rate provided by the ADSL service has been increasing every few months, and with the increase in the rate of this ADSL service, many ADSL users have become new and higher rate services. Changes have been made. However, when you actually introduce a new service, there are many cases where the acquisition rate drops compared to the previous contract service, and a lot of complaint calls are inundated to the carrier's customer support center. The situation is happening.

  This is because the high-rate service of ADSL uses signals in the high frequency band, so it can only benefit end users at short distances from the station, and various DSL parameter settings such as DSL mode are not necessarily set at each end. This is a problem that depends on the particularity of the ADSL technology, such as not being optimized by the user.

  Against this background, (1) selecting the optimum DSL parameter according to the environment for each end user and finding the setting that gives the maximum rate in the environment for each end user, (2) setting before changing the service Therefore, there is a need to develop a system that automatically implements the fact that the service is not changed when the network setting is optimal, and contributes to reducing the load on the customer support center of the telecommunications carrier.

  In addition, the applicant of the present application requests the end user to change the communication line setting for each line by a device that connects a terminal on the information network to the computer network via a communication line whose optimum operating conditions differ for each line.・ Proposals have been made for optimal and dynamic methods depending on the orientation and environment. Although it seems that (1) and (2) above can be realized with this method, the state of the communication line is determined based on the defined determination data, so that it matches the actual end user environment. Optimal settings cannot be made.

  Therefore, an object of the present invention is to solve the above-mentioned problems and to select and adapt an optimum DSL mode suitable for each end user environment when changing a DSL service, a management server, and those It is to provide a DSL mode management method and a program for use in the same.

And the DSL mode 34 (“G.992.1 Annex.I”, “G.992.1 Quad” after the optimization processing) ,...), The acquisition rate 35 (“13218”, “30563”,...) After the optimization process, and the network during the optimization process. Consisting abnormality identification flag 36. indicating whether an abnormal state such as click disconnection has occurred.

  Here, the abnormality identification flag 36 takes one of the values “true (abnormal)”, “false (abnormal)”, and “NULL (initial value before execution of optimization processing)”. .

  FIG. 3 is a diagram showing a configuration of the list holding unit 4 of FIG. In FIG. 3, the list holding unit 4 holds a list in which each line is classified based on the data of the line management data holding unit 3 obtained as a result of the optimization process.

  That is, the list holding unit 4 has a rate-up line list 41 indicating a list of lines whose acquisition rate has improved as a result of the optimization process, and the acquisition rate has decreased from before the execution as a result of the optimization process. Service unchanged line list 42 showing the list of lines that have been restored to the original DSL mode setting due to the failure, and some failure (eg, network failure) when returning to the original DSL mode during and after optimization processing Thus, a list including an abnormality occurrence line list 43 indicating a list of lines for which the DSL mode setting has failed is held.

  FIG. 4 is a diagram showing a configuration of the mode-specific / set value profile holding unit 6 of FIG. In FIG. 4, the mode-specific / set value profile holding unit 6 is for the DSL mode # 1 profile 61-1, the DSL mode # 2 profile 61-2, and the DSL mode # 3 for each DSL mode. It consists of profiles 61-3,. This DSL mode profile can be input via the data registration means 26 every time a new DSL technology comes out.

  Before the speed-guaranteed DSL mode management server 1 performs a steady operation, it is necessary to previously register the mode-specific / set value profile holding unit 6 and the monitored modem model name data holding unit 5 by the data registration unit 26. is there.

  FIG. 5 is a flowchart showing the operation of the speed guaranteed DSL mode management server 1 according to an embodiment of the present invention. The operation of the speed guarantee type DSL mode management server 1 will be described with reference to FIGS. The processing shown in FIG. 5 is realized by the management control unit 2 executing the system program of the recording medium 20.

  In the speed guarantee type DSL mode management server 1, when the system operation is started, the timer control unit 27 determines the processing start time (step S1 in FIG. 5), and when the processing time is reached, the operation control unit 21 starts the processing. To be notified. Upon receiving the notification from the timer control unit 27, the operation control unit 21 reads a list of lines whose abnormality flag is “true” from the monitored modem model name data holding unit 5 and the line management data holding unit 3 (FIG. 5). Step S2).

  Next, the operation control unit 21 obtains the modem model name, DSL mode, and acquisition of all the lines from all the subordinate devices through the device interface (A) 23-1 and the device interface (B) 23-2 via the device data collection unit 22. Rate data is collected (step S3 in FIG. 5).

  The operation control unit 21 collects data of lines not included in the list of lines whose modem model name is included in the monitored modem model name data holding unit 5 from the collected data of each line and whose abnormality flag is “true”. And is written in the line management data holding unit 3 (step S4 in FIG. 5).

  The purpose of the process of step S4 is to determine the target line for the next mode optimization process. At the same time, the optimization process is performed again for the line in which no abnormality has occurred once the mode optimization process is performed. Is not to implement. Further, writing is performed only for the line identifier 31 in the line management data holding unit 3, the DSL mode 32 before the optimization process, and the acquisition rate 33 before the optimization process.

  Next, the operation control unit 21 performs a mode optimization process (step S5 in FIG. 5). This mode optimization process will be described later. Further, the operation control unit 21 uses the data of the line management data holding unit 3 after the mode optimization processing is performed, to perform various lists (rate-up line list 41, service unchanged line list 42, abnormality occurrence line list 43). And the list is written in the list holding unit 4 (step S6 in FIG. 5).

  Here, as the rate-up line list 41, a set of lines in which the abnormality occurrence flag 36 is “true” and the acquisition rate 35 after the mode optimization process is greater than or equal to the acquisition rate 33 before the mode optimization process is extracted as a list. Is done.

  As the service unchanged line list 42, a set of lines in which the abnormality occurrence flag 36 is “true” and the acquisition rate 35 after execution of the mode optimization process is less than the acquisition rate 33 before execution of the mode optimization process is extracted as a list. .

  As the abnormality occurrence line list 43, a set of lines whose abnormality occurrence flag 36 is “false” is extracted as a list.

  Finally, the operation control unit 21 takes out the service unchanged line list 42 and the abnormal line list 43 from the list holding unit 4 and notifies the end of processing from the e-mail notification unit 25 as an attached file of the e-mail ( FIG. 5 step S7).

  FIG. 6 is a flowchart showing mode optimization processing by the operation control unit 21 of FIG. The mode optimization processing by the operation control unit 21 will be described with reference to FIGS. The process shown in FIG. 6 is realized by the management control unit 2 executing the system program of the recording medium 20.

  When the mode optimization process is started, the operation control unit 21 reads all data stored in the mode-specific / set value profile holding unit 6 (step S11 in FIG. 6). The operation control unit 21 checks whether or not there is a line that has not yet been processed among the target lines of the mode optimization process determined in step S4 (step S12 in FIG. 6).

  When there is an unprocessed line, the operation control unit 21 sets the acquisition rate 33 before the optimization process to the maximum rate as the initialization process, and the DSL mode 32 before the optimization process to the maximum rate DSL mode. “False” is assigned to each of the flags, and profiles are prepared by excluding those corresponding to the DSL mode 32 before the optimization process from all the profiles read in step S11 as the adaptive set value profile group (step in FIG. 6). S13).

  The operation control unit 21 confirms whether or not an unadapted profile still exists in the adaptive profile determined in step S13 (step S14 in FIG. 6). When there is an unadaptive profile, the operation control unit 21 uses the device interface (A) 23-1 and the device interface (B) 23-2 via the device data setting unit 24 and uses the DSLAM device (A) 7-1. And the setting is performed for the corresponding line of the DSLAM device (A) 7-2.

  After performing the setting, the operation control unit 21 considers the link-up time of the modem and waits for a while, and then reads the acquisition rate of the corresponding line (step S15 in FIG. 6). When the operation control unit 21 succeeds in reading the acquisition rate (step S16 in FIG. 6), the state flag is set to “true” (step S17 in FIG. 6), and the acquisition rate is compared with the maximum rate (step in FIG. 6). S18).

  If the acquisition rate is equal to or higher than the maximum rate, the operation control unit 21 replaces the maximum rate with the acquisition rate, and replaces the DSL mode of the profile read in step S15 as the maximum rate DSL mode (step S19 in FIG. 6).

  When there is no unadaptive profile in the process of step S14, the operation control unit 21 sets the setting value profile corresponding to the maximum rate DSL mode again for the apparatus, and then sets the maximum rate for the corresponding line. The maximum rate DSL mode and the value of the status flag are determined and held in the temporary holding area (step S20 in FIG. 6).

  When there is no target line for which mode optimization processing has not been performed in the processing of step S12 described above, the operation control unit 21 writes data to the line management data holding unit 3 for all target lines (step S21 in FIG. 6). ). At that time, the operation control unit 21 writes the maximum rate to the acquisition rate 35 after the optimization process, the maximum rate DSL mode to the DSL mode 34 after the optimization process, and the status flag to the abnormality identification flag 36, The mode optimization process ends.

  As described above, in the present embodiment, the mode optimization process sequentially adapts the mode-specific / setting value profile holding unit 6 to operate in the DSL mode with the highest acquisition rate. Even when a DSL service is changed to a service, an optimum DSL mode can be selected and adapted according to the environment of each end user, so that a service at the same rate as before the service change can be provided at the worst.

  In this embodiment, since the monitored line can be automatically determined from the accumulated data in the monitored modem model name data holding unit 5 and the line management data holding unit 3, It is possible to avoid the inconvenience of notifying the system of the line to be monitored by cooperating with each other or registering data by the system administrator.

  Further, in this embodiment, the monitored modem model name data holding unit 5 and the mode / setting value profile holding unit 6 have a simple configuration, and data registration / change can be performed by the data registration unit 26. Even when the DSL technology is introduced, it is possible to cope with the change of the system program executed by the management control unit 2 by adding the data.

  Furthermore, in this embodiment, the device data setting unit 24 and the device data collection unit 22 are arranged independently of the device interface (A) 23-1 and the device interface (B) 23-2. Even when a device (a device of another vendor) is added under monitoring, it can be accommodated in the system by adding only the device interface (A) 23-1 and the device interface (B) 23-2. This makes it easy for the system to support multi-vendor devices.
