Quality of Service (QoS) is an important concept in any network which ultimately leads to network efficiency and customer satisfaction. In this PPT, we deal mainly with the Quality of Service aspects relating to Femto Access Point (FAP) of UMTS technology. PPT mainly deals with the Guaranteed Bit Rate (GBR) implementations.
The project was a study based report on the RAN evolution path of 2.5G EDGE Networks to HSDPA. HSDPA is a 3.5G wireless cellular system, a cost-efficient upgrade to UMTS systems and promises to deliver performance comparable to today’s wireless LAN services, but with the added benefit of mobility and ubiquitous coverage. It can offer data rates of up to 14.4 Mbps which is far beyond what 2.5G and 3G cellular systems could offer. The project focuses on a two-step upgrade, first from GSM towards the deployment of UMTS/WCDMA and then towards HSDPA. It begins a new era of “Mobile broadband” services and faces competition from “WiMAX” – but with GSM services having an obvious upgrade path to WCDMA, HSDPA seems to be leading the market in several parts of the world. HSDPA is an extremely cost-effective path to higher data rates and provides more efficient use of valuable spectrum. It enables operators to compete effectively in increasingly converged markets and satisfy the need for enhanced QoS in an efficient and cost-effective manner.
Trial result HSDPA over IuR. Without this feature, DSCR (Direct Signaling Connection Re-establishment ) will occur when HSDPA user will move to another RNC
Solutions for the Texas Energy Shortage Rick Borry
Ron Seidel, PE, principal at RBS Energy Consulting and Principal Solar, Inc. board member will discuss and answer questions about his recent whitepaper, "Solutions for the Texas Energy Shortage."
Ron's whitepaper is very timely because in the summer of 2011, Texas experienced extremely low reserve margin periods throughout the state... causing average wholesale electricity prices to skyrocket to more than twice their normal level. Given that Texas is expected to add another 14 million to its population between 2010 and 2030, these shortages raise alarms about the state's ability to meet future energy demand. Success will depend upon finding the most effective way to incent the development of more capacity.
Unlike many other states, Texas has had a competitive retail market for electricity since 2001, replacing the traditional cost of a service-based regulated market. The market requires customers to choose a competitive electricity supplier and allows retail suppliers to set their prices without regulatory interference. However, regulatory action has resulted in caps being placed on system-wide wholesale power prices with the intent of protecting consumers. It is these system-wide offer caps that have limited prices, reduced potential profitability for wholesalers and restrained the development of new generation.

Mobile Music Business Models in Asia's Emerging MarketsLaili Aidi
Aidi, Laili; Markendahl, Jan; Tollmar, Konrad; Selvakumar, Ekambar; Huang, Jin; and Blennerud, Greger, In proceeding of: 12th International Conference on Mobile Business, Berlin 2013
In the telecom business, there has been a heavy competition from Internet, media and handset vendors companies. These over-the-top (OTT) players offer compiling telecom services, cause a transformation in the telecom business ecosystem, and the most challenging services posed here are media services. China, India and Indonesia, as world’s emerging markets in Asia, are predicted to take the largest share in the global mobile traffic explosion by 2015. It is critical for mobile network operators (MNOs) in this region to explore strategy for mobile media services, as mobile broadband is likely preferred
compared to fixed broadband.
In this paper, we analyze and compare mobile music business models used in these markets and structure the relation models between the key actors, using Actors, Relations and Business Activities (ARA) model. We present the economic models that are emerging, and an insight of why and how these multitudes actors are betting on currently. We found that the MNOs generally have a much stronger position compared to their counterparts in the developed markets, and the personalization services, like ring-back tone, are still a huge success. The actors tend to deliver the services by their own, rather than to collaborate in a horizontal business setting.

Master Thesis Report: Business Models for Mobile Broadband Media Services – C...Laili Aidi
The increase mobile data traffic from the emerging Internet services, especially multimedia, has posed considerable challenges for the telecom industry. Their initial mobile data services business models are generally not compatible with these emerging Internet services. Thus, there is a substantial need to investigate the suitable options to make media as a profitable telecom business sector. However, there are different challenges and opportunity factors in developing sustainable mobile media business in each market, due to the unique circumstances applied as the result of customer characteristics, mobile market situation and regulatory/law enforcement.
The first purpose of this thesis is to explore the business model options to deliver media services on top of mobile broadband. Although, we limit our focus to Indonesia, we first analyzed the worldwide patterns toward the media services in order to get a broader view of the current trend. We mapped multitudes of actor involved in digital online / on the top (OTT) media service, which together they form different types of constellation in the value network, as well as service, delivery and revenue model. We also put our focus to get the lessons learned from Spotify’s business model, by framing it using Chesbrough and Rosenbloom’s model.
The second purpose is to understand the Indonesian mobile user's characteristic toward the mobile media services. We conducted survey to 119 Indonesians, analyzed and validated the result with the correlation tests (Cronbach Alpha and Pearson correlation), within the Unified theory of acceptance and use of technology (UTAUT) framework. Our findings confirm the low willingness to pay, but an open attitude for the services. The mobile device and network quality are not the barriers for them to adopt the services, and there is a tight connection between the decisions to adopt the services with the perception that the service is popular.
Through those findings, we assessed the feasibility of the identified options and formulated the recommendations. We used our understanding about Indonesian market structure (telecom and media), regulation, and mobile user, as well as the lesson that we got from media services provisioning in Sweden and worldwide trend. We found that the pricing tiers, adjustable pricing, and differentiated features are some of the key success factors. Meanwhile, being part in the point-to-multipoint partnership with the well-known OTT player is the potential position that the Mobile network operators (MNOs) in Indonesia should take in provisioning OTT media services, rather than deliver the services by their own.
Paper - Competing or Aligning? Assessment for Telecom Operator's strategy to ...Laili Aidi
Up until recently, it was rarely direct competition between telecom operators, cable and satellite Pay-TV providers in digital TV/Video, as their business area were different and value chain was well established. However, technology advance has altered digital TV/Video landscape, made these Communication Service Providers (CSPs) cross other’s area and opened door for new actor (OTT player) to enter the market. This triggers second change in the landscape, as it potentially bypasses CSP’s role in digital media value chain.
There are generic potential options for telecom operator to address OTT service‘s treat, where the trend shows gradual shifts toward allowing or promoting. This study assesses telecom operator’s reaction strategies to react to this digital TV/Video convergence trend. Our analysis reveals two typical relation patterns in the value network, used by telecom operators based on strategy options above, which are ”point-to-point” and ”point-to-multipoint” relation model. We explore the underlining motivations that based these strategies, as well as analysis of the eco-systems: actors identification, business roles and distributed responsibilities among them, where we use ARA (Actors, Resource, Activities) point of view to model these value networks.

Analysis of WiMAX regulation in South Korea and Indonesia - PresentationLaili Aidi
Abstract—The development and rollout of WiMAX introduces several regulatory and policy issues. This paper highlights the WiMAX Regulation in South Korea, as a country that is already more mature and had become the first to implement Wireless Broadband Access (WBA) of its kind (WiBro) in the world, and Indonesia, as a country that is still in the process of formulating the reconcilable regulation. The paper begins with a brief overview of the technologies behind WiMAX and compared the market situation relative to broadband and 3G mobile networks. Next, the paper examines the potentially significant specific policy and regulatory issues for regulator in each country and competition climate between stockholders. Finally, this data was used to obtain recommendations to overcome the said problems. We found out that WiMAX may prove to be a disruptive technology for existing telecommunication and Internet sector, but careful policy effectuation can ensure that the disruption could create the maximum benefit possible in the society and market.

SNMP Project: SNMP-based Network Anomaly Detection Using ClusteringLaili Aidi
This document contains implementation report of a system that is able to monitor the network using SNMP and identify the specific possible attacks (DoS and port scan) using a cluster analysis. In the first task, the program discovers the topology of the network. After successful discovery phase, it will be able to monitor the link utilization (network link-states) for a specified period of time, and then detect the anomaly, using k-means clustering scheme [1]. These anomalies will be analyzed to recognize the attack. Moreover, this program also provides an advance feature, which is defined as optional task, as it executes online monitoring and detects the attacks using Davies-Bouldin Index as quality scoring measurement [2].

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. Scenario
Coverage type
“Urban”: Population density 2000 / km2, total area 10,000 km2.
Usage type
“MBB Substitute”, starting from 5 GB/Month in year 0, increasing
prediction 1 GB/Month each year.
User penetration
“Substitute_1”: starting from 1 % of total population in year 0, increasing
prediction 1% each year.
Operator type
“Greenfield”: has to deploy the network from scratch.
RAT options
• UMTS Macro
• HSDPA Macro
• HSDPA Micro
6. Approach
1. Coverage (km2) & User demand
Example Year 0:
• 20% coverage area means:
20 % x 10,000 km2 = 0 km2 total required coverage
• 1 % user penetration means:
1 % x (2,000 x 10,000) = 200,000 total predicted user
Total Predicted User

2. Capacity demand (Mbps)
Example Year 1:
Usage per User 6 GB/month/user, thus the user demand (UD1) is:
6 GB/month/user x 1,024 = 6144 MB/month/user
As traffic is concentrated in 4 hours / day, thus the user demand in Mbps (UD2) is:
(UD1)/(30 days x 4 hours x 60 minutes x 60 seconds) x 8
= 0.113777778 Mbps/user
Then the capacity demand for the system would be:
(UD2) x 400000 users = 45511.1 Mbps
Total Capacity Demand (Mbps)
250000 227555.6

8. Approach
3. Total equipment demand for each RAT option
Coverage achieved (CvTot)
Coverage achieved by BTS deployment, would be:
Cv = Maximum cell range * Amount of BTS
Thus, total Coverage achieved on that year (CvTot) would be:
CvTot = Cv + CvTot last years
Capacity achieved (CpTot)
Capacity achieved by BTS deployment (Cp1) would be:
Cp1 = Maximum capacity * Amount BTS
Capacity achieved by add cell deployment (Cp2) would be:
Cp2 = Maximum capacity * Cell
Where Add.Cell (Cell) is:
Cell = Amount of (Cp) BTS * (6-1)
Thus, total Capacity achieved on that year (CpTot) would be:
CpTot = Cp1 + Cp2 + CpTot last years
9. Approach
Data Line (DL)
DL = (Cp1 + Cp2) / Data line capacity
Site installation (SI) and Site build out (SB)
SI or SB = Amount of BTS purchased
Site Lease (SL) and Electricity (EL)
SL or EL = Amount of BTS purchased + Amount of BTS purchased last year
Leased Line (LL)
LL = CpTot / Leased line capacity
10. Result - UMTS Macro
