行動網路訊務負載模擬系統及其方法Mobile network traffic load simulation system and method thereof

本發明係關於一種行動網路訊務負載模擬系統及其方法,特別為一種針對涵蓋了行動訊務交換點、行動交換機、用戶本籍位置儲存器及簡訊服務中心之行動網路交換設備來建構之訊務負載模擬系統,並可模擬行動交換設備和其相連接之每條鏈路所承載訊務。The present invention relates to a mobile network traffic load simulation system and method thereof, and is particularly constructed for a mobile network switching device that includes a mobile service switching point, a mobile exchange, a user's home location storage, and a short message service center. A traffic load simulation system that simulates the traffic carried by the mobile switching device and each link to which it is connected.

由於行動通信技術之推陳出新,網路架構與功能日趨複雜,若要進行行動網路架構改接、行動設備增減或行動設備互相連接鏈路增減時,如何能事先知道各行動設備和各鏈路之訊務負載裝況,以提早釐清改接或增減是否會發生問題,並隨時進行規劃之調整,成為行動網路維運單位重大挑戰,而習知改接作業有以下的限制:Due to the innovation of mobile communication technology, the network architecture and functions are becoming more and more complex. How to know the mobile devices and chains in advance if mobile network architecture is changed, mobile devices are added or removed, or mobile devices are connected and connected. The traffic load status of the road is to clarify whether there will be problems in the change or increase or decrease, and adjust the planning at any time, which becomes a major challenge for the mobile network maintenance unit. The conventional replacement operation has the following restrictions:

1.習知改接作業都是由人工計算改接後之各行動設備及各鏈路之訊務負載情況,但由於行動設備之各種模擬訊務量、訊務處理方式、轉送路由設計和備援路由設計非常複雜,人工計算通常要花費許多時間和精力,並且很難去統計一旦行動設備或其相連接之鏈路發生故障時,其訊務量可能會發生之網路狀況變化將難以估計,因故無法正確得知改接後之訊務負載分配情況,容易造成訊務分配之誤判。1. The conventional rectification operation is the manual load calculation of each mobile device and each link after the manual calculation, but due to various analog traffic, mobile processing methods, transfer routing design and preparation of mobile devices The routing design is very complicated. Manual calculation usually takes a lot of time and effort, and it is difficult to calculate the change of network status that may occur when the mobile device or its connected link fails. For some reason, it is impossible to correctly know the distribution of traffic load after the change, which may easily lead to misjudgment of traffic distribution.

2.使用現有之傳統話務模擬系統,由於欠缺客製化之設計來處理各行動網路複雜的各種模擬訊務量、各種訊務處理方式、轉送路由設計和備援路由設計,常會造成模擬之訊務負載失真,且傳統訊話務模擬系統無法特別處理訊務備援路由之設計是否正確,成了許多電信網路維運人員無法使用傳統話務模擬系統。2. Using the existing traditional traffic simulation system, due to the lack of customized design to deal with the complex analog traffic of various mobile networks, various traffic processing methods, transfer routing design and backup routing design, often cause simulation The traffic load is distorted, and the traditional traffic analog system cannot specifically handle the design of the traffic backup route. It is a problem that many telecommunication network operators cannot use the traditional traffic simulation system.

3.維運人員於進行網路改接前,亟需要事先告警訊息以得知行動設備及其各鏈路之架構連接規劃是否有問題,若有,則必須重新規劃行動設備及其各鏈路之架構,以利負載過高情況排除,然而,目前並沒有這樣的即時分析系統,可以滿足維運之實際需求。3. Before the network personnel change the network, they need to send a warning message in advance to know if there is any problem with the architecture connection plan of the mobile device and its links. If so, the mobile device and its links must be re-planned. The structure is excluded in case of excessive load. However, there is no such real-time analysis system to meet the actual needs of maintenance.

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.
