Description

VDSL2網路端點連線能力偵測方法VDSL2 network endpoint connection capability detection method

本發明係提供一種VDSL2網路端點連線能力偵測方法，其目的除了可以開發潛在升速的客戶群之外，同時也可降低不必要之裝機成本耗費。因此在開發的過程中，藉由進階超高速數位用戶迴路(Very High Data Rate DSL，以下均稱VDSL2)有關速率的子載波參數訊號雜訊比(Signal Noise Ratio，以下均稱SNR)值，以及運用演算法來進行升速潛在速率的估算，再考量實際百對線路的影響後，最後綜合判定用戶的升速能力。The invention provides a VDSL2 network endpoint connection capability detection method, the purpose of which is to not only develop a potential customer base, but also reduce unnecessary installation cost. Therefore, in the development process, the value of the sub-carrier parameter signal noise ratio (hereinafter referred to as SNR) of the rate of the advanced ultra-high-speed digital user QoS (hereinafter referred to as VDSL2) is And using the algorithm to estimate the potential rate of the speed increase, and then consider the impact of the actual hundred pairs of lines, and finally comprehensively determine the user's speed-up ability.

隨著全球寬頻服務的快速成長，人們對寬頻服務的需求與日俱增，全球服務提供商無不積極建置寬頻網路來滿足用戶對網路頻寬與服務之需求。VDSL2技術目前廣泛地應用在寬頻接取網路中，因此服務提供商必須建置大量的網路設備，包含數位用戶線接入復用設備(Digital Subscriber Line Access Multiplexors，以下均稱DSLAM)、遠程訪問多路復用器(Remote Access Multiplexors，MiniRAM)與相關網路管理設備等，藉由先進技術設備的建置與可靠的維運機制，使得VDSL2提供的連線速率是愈來愈高。With the rapid growth of global broadband services, the demand for broadband services is increasing day by day, and global service providers are all actively building broadband networks to meet the needs of users for network bandwidth and services. VDSL2 technology is widely used in broadband access networks, so service providers must build a large number of network devices, including Digital Subscriber Line Access Multiplexors (hereinafter referred to as DSLAM), remote Access to multiplexers (Remote Access Multiplexors, MiniRAM) and related network management equipment, etc., through the construction of advanced technology equipment and reliable maintenance mechanism, VDSL2 provides a higher connection rate.

對於既有申裝較低速的寬頻上網客戶而言，若該客戶想要改申請較高速的上網服務速率時，例如由下行10Mbps的速率，改成下行50Mbps的速率，通常採供裝距離機制來初步判斷是否能升速，然而此方法存在一些問題，例如在供裝距離內的客戶，如果該線路的品質較差，或是該線路所受的干擾較嚴重，可能造成無法提供較高速的服務時，採用距離方式來判斷會產生錯誤供裝的情況；同時對於在供裝距離外的客戶，如果考量該線路的品質較佳，或是該線路所受的干擾較低，如此可以提供較高速的服務時，採用距離方式來判斷卻是不能供裝。由此可知，如僅依靠供裝距離因素來判定既有客戶線路是否具有升速條件，會產生可能之供裝誤差，因此需要額外速率估算的方法來進行輔助。在下列先前的專利技術中有提及類似的概念：CN101656555，然而此先前的專利技術只有針對ADSL2+的客戶來進行速率估算，並沒有針對目前提供較高速的VDSL2客戶來進行速率估算，同時針對速率估算的方法，此先前的專利技術只採用設備所提供的初始最大可達速率參數來估算，此部分與本篇專利所採用的參數明顯不同，加上一旦設備商所採用的運算技術不同，導致所提供的初始最大可達速率參數數值有很大的誤差時，那麼將會影響速率估算的準確性。For broadband Internet customers who have applied for a lower speed, if the customer wants to apply for a higher speed Internet service rate, for example, the rate of 10 Mbps downstream is changed to the rate of 50 Mbps downstream, the distance mechanism is usually adopted. To determine whether it can speed up, however, there are some problems with this method. For example, customers within the supply distance may not be able to provide higher-speed services if the quality of the line is poor or the interference to the line is severe. When using distance, it is judged that the wrong supply will occur. At the same time, for customers outside the supply distance, if the quality of the line is better, or the interference of the line is low, it can provide higher speed. In the service, the distance method is used to judge but it cannot be installed. It can be seen that if only the supply distance factor is used to determine whether the existing customer line has a speed up condition, a possible supply error may occur, so an additional rate estimation method is needed for assistance. A similar concept is mentioned in the following prior patents: CN101656555, however, this prior patented technology only rates the ADSL2+ customers and does not rate the current high speed VDSL2 customers, while targeting rates. The method of estimation, this prior patented technology is only estimated using the initial maximum reachable rate parameter provided by the device. This part is significantly different from the parameters used in this patent, and the calculation technique used by the equipment manufacturer is different. When the initial maximum reachable rate parameter value provided has a large error, it will affect the accuracy of the rate estimation.

由此可見，上述習用方式仍有諸多缺失，實非一良善之設計，而亟待加以改良。It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

本案發明人鑑於上述習用方式所衍生的各項缺點，乃亟思加以改良創新，並經多年苦心孤詣潛心研究後，終於成功研發完成本件VDSL2網路端點連線能力偵測方法。In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally successfully developed and completed the VDSL2 network endpoint connection capability detection method.

本發明之目的在於針對VDSL2用戶進行升速潛在客戶的開發，利用本專利所提出的方法，藉由VDSL2有關速率的子載波參數SNR值，以及運用演算法來進行升速潛在速率的估算，再考量實際百對線路的影響後，來綜合判定用戶的升速能力，同時亦也可降低不必要之裝機與維運成本的耗費。此估算速率的方式，可加強只用在供裝距離的方法來進行服務速率判別的不足之處。The purpose of the present invention is to develop a speed-up potential customer for a VDSL2 user, using the method proposed in this patent, using the VDSL2 rate-dependent subcarrier parameter SNR value, and using an algorithm to estimate the rate of the speed increase, and then After considering the impact of the actual hundred pairs of lines, it can comprehensively determine the speed-up capability of the user, and at the same time reduce the cost of unnecessary installation and maintenance costs. This method of estimating the rate enhances the inadequacy of the service rate discrimination only by the method of supplying the distance.

傳統上VDSL2的供裝原則，係先以用戶的供裝距離來進行判斷是否能供裝，而此種方式可能會產生兩種議題，第一個議題是為何該用戶的距離在供裝距離內，但是實際上是無法達到該服務速率；另一個議題是用戶的距離雖然超過供裝距離，實際上卻可以達到該服務速率。由此可知，傳統技術上的確是有改進與補強的部分Traditionally, the principle of supply of VDSL2 is based on the user's supply distance to determine whether it can be installed. This method may have two issues. The first issue is why the user's distance is within the supply distance. However, the service rate cannot be reached in reality; another issue is that the user's distance can exceed the supply distance, but the service rate can actually be reached. It can be seen that the traditional technology is indeed a part of improvement and reinforcement.

為達成上述發明目的之應用於VDSL2網路端點連線能力偵測方法，本提案提出一套完整的供裝流程技術。本發明所提出之應用於VDSL2網路端點連線能力偵測方法，包含五個單元：(一)SNR導向速率預估模組、(二)百對線干擾之速率修正估算模組、(三)升速潛在客戶判定模組、(四)進階超高速數位用戶迴路數位用戶線接入復用設備資料庫(High Data Rate DSL Digital Subscriber Line Access Multiplexors Database，以下均稱VDSL2 DSLAM DB)與(五)速率估算與修正資料庫。首先輸入進行速率預估時所需的參數資訊，資訊包含進階超高速數位用戶迴路數位用戶線接入復用設備(High Data Rate DSL Digital Subscriber Line Access Multiplexors，以下均稱VDSL2 DSLAM)類型、進階超高速數位用戶迴路用戶前端(High Data Rate DSL customer premises equipment，VDSL2 CPE)設備類型、該線路目前使用的寬頻服務速率與該線路周遭其他線路干擾的相關鄰對資訊(Neighborhood Information)等。接著利用在該線電路於設定速率的連線下，從完成連線後的設備內讀取該線路速率的SNR相關資訊，來計算出一個速率預估參考值；然後再考慮到未來同一電纜百對線內多對的實際供裝干擾情況，進行預估速率的調校來扣除其可能的速率損失，以避免因新增用戶後影響既有用戶的服務速率；最後所得到的速率預估值，此值除了能發掘潛在升速用戶群外，同時也可找出線路距離雖然位於供裝距離內，但其實際升速後的速率卻是達不到預期速率的線路。In order to achieve the above-mentioned invention, the VDSL2 network endpoint connection capability detection method is proposed. This proposal proposes a complete set of supply process technology.

Then, using the line at the set rate of the line circuit, reading the SNR related information of the line rate from the completed device to calculate a rate estimation reference value; and then considering the same cable in the future. For the actual supply and interference situation of multiple pairs in the line, the estimated rate is adjusted to deduct the possible rate loss to avoid affecting the service rate of the existing users after adding users; the final estimated rate is obtained. In addition to discovering the potential speed-up user group, this value can also find out that the line distance is within the supply distance, but the rate after the actual speed increase is not the expected rate.

The speed up potential customer decision module 13, the VDSL2 DSLAM DB 14 and the rate estimation and correction database 15. At the beginning of the method, the SNR-directed rate estimation module 11 is executed first, and then the result is subjected to a rate-corrected estimation module 12 for the hundred-to-line interference, and finally the final potential rate prediction value is entered into the speed-up potential customer decision mode. The group 13 determines whether the speed is up or not. When performing the SNR-oriented rate estimation module 11 rate estimation, the basic data input 111 of the circuit to be tested must be performed, including the currently used broadband service rate setting, the VDSL2 DSLAM device type, the VDSL2 CPE device type, and the correlation information.
