行動數據通信費率組合之研究-以GPRS為例 / A Study of Mobile Data Pricing Package -- GPRS Case

陳建國, Edward Chen Unknown Date (has links)
費率組合在電信業市場上行之有年,但長久以來,電信業一直以傳統的語音服務計費模式套用在所有的服務上,其中通話費的部分則是以通話時間作為計費的基礎,甚至連架構在語音服務上的數據傳輸也是如此。新引進的整合封包無線電服務(General Packet Radio Service, GPRS)在技術本質上與語音服務有很大的差異,因此計費方式也必須作一番變革,以傳輸量作為計費的基礎是較佳的選擇。  由於GPRS屬於寬頻數據網路,再加上無線電資源的有限性,在傳輸品質上的要求也較高,GPRS在設計時就已經規劃了支援「服務品質(Quality of Service,QoS)」。因此,品質因素也應被列入計費的要項之一。  本文嘗試提出一個GPRS的計費架構,並找出所有的計費因子,使未來經營GPRS的電信業者的行銷人員及計費系統設計人員有一個依循的準則。而在實例中也的確發現本文所提出的GPRS計費架構,可以應用在現實的計費系統上,提供各式各樣的費率組合。 / Pricing Package was used in telecommunications industry for many years. However, the operators always use the conventional voice service packages to cover the data services. The charge for every call is duration based but it cannot be applied for new introduced technology, e.g. GPRS. The technology of GPRS is quite different with the voice services; the charging model will be different as well. A volume-based charging model is an ideal way.  GPRS is a broadband mobile data service. According to the limitation of wireless resources, the demand of quality of service is high. GPRS was designed to support QoS (Quality of Service) which can be considered as a charging factor.  This material tried to propose a GPRS charging architecture and find out all of the charging factors. The marketing people and charging system designers of GPRS operators can create their own pricing packages based on this GPRS charging architecture. In the case study, we found that this GPRS charging architecture can be applied to the real world charging systems and provide kinds of pricing packages.

應急蜂巢式行動通訊網路之群組通訊設計 / Agency Communication Design for Contingency Cellular Network

張惠晴, Chang, Hui Ching Unknown Date (has links)
在大型天然災害發生之後的黃金救援時期,災民存活率和救災效益之提昇極度仰賴於一個順暢的通訊系統。由歷年來大型災變的經驗中我們可知,行動通訊系統其實是不可靠且極為脆弱的,基地台之電力供應中斷或連接後端固定網路線路(Backhaul)之損毀都將使得通訊系統癱瘓而影響救災工作效率。 本研究提出一種新的應急通訊系統,利用原有行動通訊系統中未損毀但失去連網能力的基地台,藉由臨時供應的電力恢復其運轉,並以無線通訊設備與鄰近基地台互連建構一個臨時應急性的網路,稱為應急蜂巢式行動通訊網路(Contingency Cellular Network,CCN),供災區內手機用戶進行通訊。由於災區內部通訊的對象通常是一個特定的群組角色,而非一個特定人員,而災民與救災人員也不知彼此所在位置及聯絡的方式,因此無法以平常的撥號方式發起呼叫。本研究以CCN網路架構為基礎,設計並實作群組通訊模式,讓災區內人員以簡碼方式向任一群組發起呼叫並建立通話。 為驗證CCN群組通訊設計之可行性及效能,我們以IEEE802.11 Wi-Fi無線網路環境建置模擬系統,並以Android平台手機搭配VoIP軟體模擬手機與系統連線以進行通話。最後設計了一連串的實驗評估本模擬系統之效能。從實驗結果可知,本系統可於短時間內即時回應使用者註冊需求及完成通話連線處理;當通話數在30通以下時,Mouth-to-Ear Delay (MED) 值可維持在400ms以下,語音品質控制在一般VoIP使用者可容許的範圍之內。本實驗可作為未來改進系統功能和建置架構之參考依據。 / When stricken by a catastrophic natural disaster, the efficiency of disaster response operation is very critical to life saving. The efficiency of disaster response operation is greatly depending on communication systems. However, they were usually not dependable, including cellular networks, and often crashed due to power outage and backhaul link breakage. The failure of communication systems caused a big coordination problem to many disaster response operations. This thesis proposes a Contingency Cellular Network (CCN) by connecting isolated base stations to survival base stations using long-range wireless links to restore part of cellular network functionality. People can use their own cell phones for emergency communication in the disaster areas. CCN will be able to support many disaster response workers in the early hours of catastrophic natural disasters, thus to save many lives. Since the receiver of a phone call in a disaster area is usually a resource (agent), not a particular person, we designed a special Agency communication mode for CCN allowing CCN users to initiate a phone call to a nearby resource by dialing a designated agency number, instead of a real phone number. To verify our design, we implemented an emulated CCN system using an IEEE 802.11 Wireless LAN to mimic the CCN network and Android small phones with VoIP software to mimic user terminals. Finally, we conducted a series of experiments to evaluate the performance of the emulated system. The experimental results show that the emulated system can respond promptly to the user registration and call set-up requests. Mouth-to-Ear Delay (MED) can be effectively controlled below 400 ms when there is no more than 30 calls originated. This system may be used as reference for the future development of contingency communication networks.

考慮資源運輸路徑之應急蜂巢式行動通訊網路建置排程 / Resource Delivery Path Dependent Deployment Scheduling for Contingency Cellular Network

高采衣, Kao, Tsai I Unknown Date (has links)
當發生大規模的地震或強烈的颱風等重大天然災害時,通訊系統常常隨著電力與交通系統的損毀而癱瘓。由歷年大型災變中多數災區內之行動通訊系統全面中斷即可印證行動通訊系統其實是極為脆弱的,然而有效運作的通訊系統卻是災情傳遞、資源調度及救災是否順利的關鍵因素。本文所探討的應急通訊系統利用倖存的連通基地台和斷訊卻沒有損毀的基地台,以無線電連接起來建構一個臨時性的通訊系統,稱為應急蜂巢式行動通訊網路(Contingency Cellular Network,CCN)。由於各地災情狀況不完全相同,CCN的建構順序必須考慮災區的輕重緩急、時間的急迫等因素依序建構。因此當CCN拓樸規劃完成後,根據CCN拓樸、各地災情嚴重程度以及拓樸中基地台間的相對距離(運輸時間)進行基地台建構排程規劃,以達到最大的總救災效益。 本文考慮各基地台所能發揮的救災效益、所需建構時間、以及運輸工具從任一基地台到另一基地台所需運輸時間,提出兩個適合CCN拓樸樹狀結構的考慮資源運輸路徑之最佳化排程模型CCNDS-AC和CCNDS-UC。CCNDS-AC限制建構順序必須從連網台往下循序建構,但CCN-UC則否。因發生突發性大型天然災害時,可容許的計算時間相當短暫,因此提出了兩個快速的啟發式演算法DS-ACG與DS-UCB,可在短時間內求出一組相當逼近於最佳解的建構排程順序,與DS-UCB相互比較。本文以電腦模擬的方式進行小規模實驗與大規模實驗評估,並且用Genetic Algorithm來比較啟發式演算法的效能。結果顯示DS-UCB明顯優於DS-ACG及Genetic Algorithm。在小規模實驗中DS-UCB可求得與最佳解的總救災效益誤差平均約0.9%的近似最佳解建構順序。而在大規模實驗下, DS-UCB與十萬個解中的最佳解─pseudo optimal solution相較,總救災效益平均高出約16.7%,而總救災時間平均約少了19.4%。 / When stricken by a large-scale disaster, the efficiency of disaster response operation is very critical to life saving. However, cellular networks were usually crashed in earthquake, typhoons or other natural disasters due to power outage or backhaul breakage. Unfortunately, the efficiency of communication system is a critical factor to the success of disaster response operation. We designed a contingency cellular network (CCN) by connecting physically intact but service-disrupted base stations together with wireless links. Since the transportation capacity may be very limited, scheduling of CCN deployment order according to the demand of disaster operation and traveling time between base stations becomes an important issue. We propose two optimization models: CCN Deployment Scheduling Antecessor Constrained Problem (CCNDS-AC) and CCN Deployment Scheduling Unconstrained Problem (CCNDS-UC), aiming to maximize the efficiency of disaster response operation. Both problems are proven to be NP Hard. We also designed two rapid heuristic algorithms, DS-ASG and DS-UCB to solve the problems respectively when it is needed in urgent. Finally, we evaluated the proposed algorithms against optimal solutions (in small cases only) as well as genetic algorithm by simulation. The experimental results show that DS-UCB outperforms all other algorithms. In small scale cases, the profit obtained by DS-UCB is only 0.9% smaller than what the optimum solution can get. In large scale cases, as compared to the pseudo optimum solution, which is the best solution among 100,000 solutions, DS-UCB outperforms pseudo optimum solutions in profit by 16.7%, and in traveling time by 19.4%, both in average.

2G無線電頻譜回收之研究:以澳門「全城3G」為例 / A Study on 2G Spectrum Reallocation in Macau

黃首豪, Wong, Sao Hou Unknown Date (has links)
澳門電信管理局在2012年1月推出「全城3G」計劃,規定2012年7月8日停用所有GSM服務,16萬2G用戶要在半年內轉移到3G服務,但是外地遊客仍可繼續在澳門使用2G漫遊服務,政府希望透計劃推動3G服務的發展,讓無線電資源更具效率地利用,然而在計劃推行期間澳門出現多宗電信故障,加上澳門廉政公署就「全城3G」計劃所發表的調查報告指有關計劃過份介入市場運作,使得本地用戶失去選擇權,損害用戶及業者的權益,而且不符合公共利益,最終「全城3G」計劃無法如期實行,各業者的2G執照與其3G執照一同延長有效期至2023年6月4日。   本研究利用文獻分析法,透過蒐集澳門「全城3G」計劃的相關資料,分析澳門「全城3G」計劃的得失,與此同時借鏡與澳門政治體制相似的香港政府的頻譜政策,檢視兩地政府在回收2G頻譜的成效。本研究綜合分析下發現澳門與香港回收2G頻譜最大的差異在於香港回收的是兩個閒置的CDMA及TDMA系統,對業者有一定的影響,但是影響民眾的範圍卻很小,而且給予3年緩衝的時間讓業者轉移用戶,而澳門則是停用一個在世界上仍算主流的GSM服務,而且要在半年內轉移十多萬用戶到3G,加上在過渡期間出現5宗電信故障,讓民眾質疑計劃的可行性,最終把技術問題變成社會問題。因此本研究建議政府未來要避免直接介入市場,以間接的方式例如徵收階梯式的頻譜使用費來推動行動通訊業發展,回收頻譜時要以平穩適度的方式進行,以及提高電信故障的罰款。 / In January 2012, the Telecommunications Regulation Bureau of Macau (DSRT) announced its decision to scrap the city’s 2G network and rely solely on 3G capabilities. Effective on July 8, 2012, the policy change left about 160,000 local users without 2G service, primarily affecting local tourists still on the 2G roaming network. DSRT stated that the objectives of its decision were to create more investment opportunities and to facilitate the adequate diversification of economic development. However, during this time, two mobile operators failed to provide stable and adequate network services and the Commission Against Corruption (CCAC) of Macau stated that DSRT’s decision deprived consumers of their right to choose their own cellular network and their right to fair treatment. This prompted the 2G service cancellation to be further postponed until June 4, 2023. This study used literature analysis to review the termination of the 2G mobile network in Macau, and to examine the 2G spectrum reallocation in Hong Kong. This study found that Hong Kong terminated two unused mobile network services (CDMA and TDMA), while Macau is planning to scrap a GSM service which will affect about 150,000 users in Macau. Therefore, opposition to network terminations are greater in Macau than in Hong Kong. At the same time, the failure to provide adequate mobile services by two network operators in Macau led to public mistrust of the government. This study suggests that 1) the DSRT should not have used administrative means to force consumers into using a specific mobile system, and 2) the DSRT should have amended the penalties for mobile operators to closer reflect the current social situation.

應急蜂巢式行動通訊網路之分散式資料庫設計 / Design of Distributed Database for Contingency Cellular Network

張宜蘋, Chang, I Ping Unknown Date (has links)
歷年發生的大型天然災害中,行動通訊系統常常會因為道路、橋樑、電力的損毀而導致嚴重癱瘓,進而影響災後救援工作的進行,行動通訊系統其實是不可靠且極為脆弱的。為使災區能夠快速地恢復通訊,本研究提出一種應急通訊系統,利用無線通訊,將這些無連線能力的基地台連接起來,並利用存活可連至核心通訊網路的基地台,建構成為一個臨時性的通訊系統,稱為應急蜂巢式行動通訊網路(Contingency Cellular Network,CCN),供使用者在災區內進行通訊。由於資料庫的可靠度在行動通訊網路中具有舉足輕重之地位,本論文旨在利用分散式架構提高CCN網路資料庫的可靠度,進而提高系統可靠度。我們先分析資料表的特性,並依據各資料表的特性以及資源之多寡,設計相應的分散式架構。 我們利用樹狀拓樸的簡單特性,提出三種分散式架構:(1)用於群組資料表的階層備援式架構、(2)用於HLR資料表的階層備援式架構,以及(3)用於HLR資料表的鄰近階層備援式架構。這三種架構都利用了樹狀拓樸的簡單特性,大幅簡化了資料庫的查詢及更新程序。我們以可用度及平均總成本,以評估各架構在不同的情形下之最合適架構,並觀察在各架構下,其系統可用度與平均總成本之間的關係,由結果可知,在群組資料表儲存架構中,若追求高系統可用度,可選擇高儲存密度之架構,反之,若追求較低的成本,可選擇低儲存密度之架構。而在HLR資料表儲存架構中,階層備援式的系統可用度與平均總成本比鄰近階層備援式來得高,表示階層備援式耗費較多成本,但可用度也較高,故在建置時可依實際情況來選擇合適的架構儲存。 最後,為驗證分散式資料庫架構之可行性,我們利用數部筆記型電腦及Android平台手機來建置階層備援式及鄰近階層備援式架構,並測量在此二種架構下於通話建立時所耗費的時間,從模擬結果可知,此二種架構皆可快速建置並可立即通訊,惟鄰近階層備援式所耗費的通話建立時間略長,但仍在可容許範圍之內。 / When stricken by a catastrophic natural disaster, the efficiency of disaster response operation is very critical to life saving. The efficiency of disaster response operation is greatly depending on communication systems. However, they were usually not dependable, including cellular networks, and often crashed due to power outage and backhaul link breakage. The failure of communication systems caused a big coordination problem to many disaster response operations. This thesis proposes a Contingency Cellular Network (CCN) by connecting isolated base stations to survival base stations using long-range wireless links to recover part of cellular network functionality. People can use their own cell phones for emergency communication in the disaster areas. CCN will be able to support a large number of disaster responders with limited resources in the early hours of disasters, thus to save many lives. Because the reliability of database plays a very important role in the CCN, this thesis proposes a distributed database architecture to improve the reliability of database so as the reliability of CCN. We take advantage of the simplicity of CCN tree topology to design three distributed database architectures: (1) Hierarchical Redundancy Architecture for “Group_Member ” table, (2) Hierarchical Redundancy Architecture for “HLR” table, and (3) Hierarchical Neighboring Redundancy Architecture for “HLR” table. The tree topology greatly simplified the query and update procedures. We use availability and average total cost to analytically evaluate all three architectures trying to identify the most appropriate architecture under different circumstances. Based on our evaluation results, CCN operators can choose the most appropriate architecture according to their realistic circumstances. Finally, in order to verify the feasibility of the proposed architectures, we implemented a simplified prototype using several laptops and Android mobile phones. The Hierarchical Redundancy Architecture and the Neighboring Redundancy Architecture were implemented. The results show that both architectures can be functional with reasonable performance except that Hierarchical Neighboring Redundancy Architecture may take longer time, but in a tolerable range, to setup a call.

應急蜂巢式行動通訊網路的多路徑網路拓樸設計 / Design of Multi-path Network Topology For Contingency Cellular Network

王鈞賦, Wang, Chun Fu Unknown Date (has links)
當發生大規模地震或強烈颱風等大型天然災害,其災後72小時為人命搜救之黃金期。由歷來的大型災變中,可知行動通訊系統其實極為脆弱且不可靠,而通訊系統癱瘓將影響救災工作之成效。本論文中探討的應急通訊系統利用倖存之連通基地台和斷訊卻沒有損毀的基地台,以無線電互相連接成一個轉送拓樸以建構臨時性通訊系統,稱為應急蜂巢式行動通訊網路(Contingency Cellular Network,CCN)。 在災難發生後,災區通常有許多須要較高通話需求的關鍵區域,其通話需求遠高於輕度災區,建置CCN時必須優先保障其通訊需求,我們先前之研究所提出的樹狀轉送拓樸其結構較脆弱,若任何一個link斷訊失去轉送功能,則其節點以下的使用者通訊將受到影響,導致任何一個節點對外通訊能力非常脆弱,影響CCN之可用度。為了提升CCN之可用度,我們提出了多路徑的CCN網路拓樸解決方案,在本方案中,每個關鍵區域都有數條對外通訊的連線。 本論文以各基地台通訊範圍內的通訊需求人數與災區毀損程度,作為效益參數,在有限緊急修復資源下,將問題塑模為一個類似K-Maximum Spanning Tree問題的Length Bounded Disjoint K-Path Max-Profit Mesh問題,我們證明它屬於NP-Hard問題,並且提出快速且效能不差之啟發式演算法,可在緊急時建立應急蜂巢式行動網路的多路徑網路拓樸。本文以電腦模擬方式,進行實驗以驗證我們的模型之適切性,並評估多路徑拓樸可提升之CCN可用度,實驗結果可提供使用者依不同的CCN可用度及總救災效益需求,選擇所需之多路徑數量。 / When stricken by a catastrophic natural disaster, the golden 72 hours is very critical to life saving. However, communication systems including cellular networks often crashed due to various causes making big impact to the efficiency of disaster response. Our research proposes the Contingency Cellular Network (CCN) by connecting disconnected base stations together using wireless links to form an overlay Ad Hoc network over a disconnected cellular network.   In our previous study, we proposed a tree topology to construct CCN, which is vulnerable since a single link failure may have a big impact to the availability of CCN. This thesis proposes a multi-path topology to enhance the availability of CCN such that the selected critical areas will have redundant communication paths connecting to the core network and thus, have higher resiliency against link failure. We model the CCN Multi-path Network Topology Design problem into a combinatorial problem, called Length Bounded Disjoint K-Path Max-Profit Mesh Problem. We take the degree of emergency and the population of each stricken area as the priority measure as well as the amount of emergency recovery resources as the capacity constraint in the topology computation model. The problem is proven to be NP Hard. Therefore, we designed an efficient heuristic algorithm (HLBDK) to solve the problem when it is needed in urgent. Finally, we evaluated the proposed algorithm by simulation. The simulation results show that the average performance deviation of the proposed heuristic algorithm away from the optimal solutions is smaller than 7% in all cases. A significant improvement in the availability can be obtained by using multi-path topology at a reasonable performance degradation. Our research results provide users a fundamental base to determine their availability requirement at a countable performance degradation.

以產品循環理論探討企業產品切入時機之選擇-以行動終端機市場為例

王士章, Wang, John S.C. Unknown Date (has links)
產品循環與國際貿易理論提出後, 有許多的相關報告與驗證, 但是甚少是以企業的觀點來切入探討分析。 台灣在過去數十年間快速的經濟發展, 由農業社會轉入工業社會, 對經濟的貢獻上, 也由勞力密集產業轉變為技術密集與資本密集的產業。 而這一切的改變是否有脈絡可循, 我們認為產品生命循環理論是一個非常重要的參考理論根據。 因而我們嚐試以企業的角度, 並由手機產業之實務資料與資訊的融合與分析, 套用產品生命循環的理論模型, 同時探討分析國際採購因素, 以相互對照並探討出其關聯性與脈動模式。 論文中, 我們先從行動通訊技術概論開始導入, 以了解行動通訊技術的演進概況。 並藉由全球行動終端機之產業產銷概況, 先了界該產業世界輪廓與局勢。 並對照亞洲主要手機生產國家, 如台灣、中國大陸、日本與韓國等之行動終端機產業與其產銷狀況, 及比較手機之技術領先國近年來在本產業生產的變化, 以該產業的生產國度轉移情況, 驗證產品生命循環理論與國際貿易關係, 同時探討平均國民所得因素對在手機產業之產品生命循環影響的關鍵程度。 同時, 我們也以台灣的手機相關企業為例, 探討其繼個人電腦產業之後, 成功的以技術模仿國的角色接替並取代了領先國的產品設計與生產的成功因素, 並分析技術模仿國的新產品導入時機與關鍵因素。 另外, 我們也企圖分析探討韓國及其相關的企業, 如何以技術模仿國的地位, 運用其所能掌握的優勢及不同的產品策略, 成功的開創出另類的“新產品”定位, 藉以擴大市場佔有並獲取利潤的極大化, 以探討技術模仿國的新產品導入的策略。

Not only expedites the mobile telecommunications technology to IMS and the All-IP network development, but also urges the mobile telecommunications service provider in all aspects of marketing, service, billing and network infrastructures migrate to the wireless and wire-line network fusion and the vision of digital convergences. After the restriction of operation licenses released by government, the mobile telecommunications service providers invest a large amount of funds on new business development. Relying on the quick transmission speed superiority, may develop more mobile value-added service content. We expect to have more another revenue increasing objects while the voice-only service revenue mutuality. Nevertheless, the mobile telecommunications industry under the large-scale investment has not had the anticipated benefit, the industry hope we can let the industrial innovation to produce the “Killer Applications” that guides the Taiwan mobile telecommunications industry to find the high profitable blue sea market. The research expects that, by the penetration analysis mobile telecommunications industry value supply chain the difficult position which bumps into in transport business developing process, and how faces the innovative technology and the business model appraised and development, is facing the indefinite market and the technology, analyzes the industrial innovation the competitive strategy and the key success factors, provides Taiwan the mobile telecommunications entrepreneur to manage the business strategies and suggestions. In order to assist Taiwan in mobile telecommunications market industrial innovation ability, promotes the entrepreneur to the value-added service field and motivates the communication equipment market innovative decision-making accuracy, impels the Taiwan telecommunications market by the time the vigorous development. The research is based on the viewpoint of disruptive technology issued by Clayton M. Christensen to leverage the analysis model of disruptive innovations and resource, process and value theorem; analyzes the five types of consumers by Technology Adoption Life Cycle model issued by Geoffrey A. Moore to investigate how telecommunications industry analyzes the chasm of innovations and how to adopt the early majority of market. In the interview of 5 enterprises across Taiwan mobile telecommunications industrial value chain, we make good communications and share opinions about all the issues of the method of innovation driven, risk assessment on innovations, how to manage innovations, to face problems and resolutions on industrial innovation. By leveraging the entire reference thesis, issued papers and theorem, the trends of market, analysis of market, and technology issues in the mobile telecommunications industry, collaborate with case study of Taiwan mobile telecommunications industry to study and make comments and conclusions on this topic. Also, we provide the suggestions on governing policies, industry strategies, and further research direction. A.Conclusions: 1.Nearby the front end of industry value chain, technology driven innovations methodology is highly enhanced and focused; Nearby the rear end of industry value chain, market driven innovations methodology is highly enhanced and focused. Disruptive technology is possibly occurred in any section of industry value chain. 2.The two major risk factors, market and technology, need to be handled together while manage disruptive innovations. It would make success to assess at least one of two major risk factors and they are all related to financial variables. 3.Innovation is always occurred in the border of organizations which is supported by key performance indicator setting of different major products and necessary financial funding. 4.The mobile telecommunications industry grows by major inferences of correct governing policies and proper regulations issued by technology management department of government. B.Suggestions: 1.For government: a.Base Station System: Coordinate all operators to co-construct the system to speed the integration of broadband wireless access technology to resolve the network quality issues. b.Technology platform and content industry: Collaborate with the enterprises of industry chain to support the research and development by proper industry regulations. 2.For wireless operators: a.Research on wireless consumer behaviors: Coordinate all operators to invest subscriber behaviors and statistic analysis in local market to learn how to produce the killer applications. b.Content and service platform: Proactively involve the content service developing and technology platform integration to develop the content industry as win-win purpose. c.Proper subscriber fare: Charge wireless consumers by the value of requisition and cost driven factor.
