Quality of Service and Mobility driven cognitive radio Systems ( QoSMOS )

1. Quality of Service and Mobility drivencognitive radio Systems (QoSMOS) Presented by: HiraBashir (10-MS-CP-02) Kanwal Saeed (09-MS-TE-02)

2. Introduction • QoSMOSis an FP7 Integrated Project. • It is about flexible spectrum access, with managed QoS and mobility. • Its main ingredients are: • Value chain development • Spectrum portfolio management • Integration with core networks • Flexible terminals and, • Demonstration • Duration is 36 months from January 2010 • Budget: Total =14.5M€

3. Cognitive Radio Systems Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. This alteration of parameters is based on the active monitoring of several factors in the external and internal radio environment, such as radio frequency spectrum, user behaviour and network state.

4. Motivation: • The proportion of voice traffic as a function of the total is becoming less, the revenue generated is not in proportion with the traffic increase and the gap between traffic growth and revenue will get larger. • At present there are two ways that a user may obtain mobile broadband services, one is • Using a mobile network operator (MNO) who employs licensed spectrum • Other is to use a fixed network operator with unlicensed spectrum on a WiFi service.

5. Continued… • Making use of technology and service neutral spectrum opportunistically is a principal focus of QoSMOS. • The opportunistically obtained spectrum can be used for congestion relief during peak loads in licensed spectrum, or to enhance existing services and / or provide new services without the need for acquiring additional licensed spectrum

6. Main Objectives • To provide a platform for efficient radio access to future networks • Under this are two S & T objectives • Cognitive wireless access provision • Network support provision • And two non-S & T objectives • Use case development • Preparation of regulatory policies • QoSMOS provides a framework to allow secondary use of spectrum to provide indoor and outdoor broadband mobile communications

7. Continued… • Opening up an alternative to either schemes currently used by Mobile Network Operators (MNOs) or fixed operators i.e., employing licensed spectrum and unlicensed spectrum respectively • QoSMOS is driven largely by industry, to provide a long term solution to ever-increasing data demand, and the ever-decreasing willingness for users to pay for it. • The framework will allow networks to grow as they are needed and will have the flexibility to allow custom application development.

8. Beneficiaries of QoSMOS • End User: who will have a better experience • Network Operator: who will have access to large amounts of radio spectrum for free • Entrepreneurial Service Provider and Application Developer: who will have a flexible and efficient delivery platform • Vendors: who will have new markets

9. Key Issues • The key issues that the project will tackle are: • Sensing, database and other methods of avoiding interference from secondary users to primary or other secondary users, • Developing metrics for spectrum occupancy for decision making and micro-trading, • Development of QoS and mobility management in cognitive radio and integration with core networks, • Researching best methods for cognitive radio terminal designs, • Spectrum portfolio management

10. Concept of QoSMOS

11. Approach: • The QoSMOS concept includes the use of two cognitive managers (CM), which operate on different timescales and amounts of radio resource • The lower one in the figure is centralized and operates on a longer timescale, it builds a portfolio of the available resource in a particular region. • This CM manages a set of rules, whose parameters can be initially programmed for different regulatory regimes. • The upper CM is distributed and operates on a shorter timescale, allocating spectrum to individual wireless streams from the portfolio, also to a set of rules.

12. Continued… • Equipment is required to have highly sophisticated sensing mechanisms and a system of metrics which enable them to correctly detect temporarily and/or spatially unused spectrum (the so-called spectrum holes) and make decisions on whether to use these without causing harmful interference to other users.  (cognitive approach) • Cost savings will be achieved through massive reuse of spectrum resources without the burden of large upfront investments by using a combination of distributed (from user) & centralized triggers (from network)

13. Allocation of Workpackages to Objectives:

14. Workplan There are 9 Work packages that aims to achieve significant impact, both in terms of business gain through new service opportunities that will arise with increased exploitation of hitherto underused spectrum, but also in terms of technology development and standardization.

15. External Advisory Board – Objectives • The EAB is a carefully selected group of organizations who are not partners of QoSMOS, but whose expertise can be very valuable to help steer the project • The EAB is a key mechanism for guiding and pointing out the wider political and societal implications of the research undertaken • The organizations involved in the EAB will discuss the wider implications of the QoSMOS outcomes and will feed back their thoughts and deliberations • Furthermore, they will help position the QoSMOS outputs in the relevant regulation groups (including ITU)

16. Expected Impact • The impact will be the availability of a viable alternative mobile broadband delivery platform which is low-cost, has QoS management and can support mobility. • The project will provide the necessary framework and critical technical building blocks to enable actors in the value chain, from vendors to applications providers, to differentiate themselves and bring CR systems to market
