1 Standardising the mechanisms for communicating configuration information across a reconfigurable network Craig Dolwin Feb 2007

2 A common language for the communication of reconfiguration information Objectives Challenges Requirements Functional Description Language (FDL) Visions and a Scenario Work being done in E2R (phase 1 & 2 ) Other work in this area SDR Forum Commercial Working Group Summary and Conclusion 2 / ETSI workshop on SDR and CR

3 Objective To develop a generic and universal mechanism for requesting a specific functionality (e.g. a RAT ) from a wireless platform 3 / ETSI workshop on SDR and CR

4 Challenges being addressed Over 2 Billion Handsets in the world World Wide Roaming Proliferation of Multi-Mode platforms Spectrum De-Regulation A move towards SDR Reduce NRE costs Enhanced tracking of market demands 4 / ETSI workshop on SDR and CR

5 Requirements Need a common mechanism/protocol to support the updating and modification of functionality Platform and System independent Guaranteed real-time reliability Physical Layer, Protocol Stack, Applications, MMI 5 / ETSI workshop on SDR and CR

6 Functional Description Language (FDL) RAT independent Platform independent Scalable Contains information about Timing/latency constraints Bandwidth requirements Precedence information Supports real-time and power conscious implementations 6 / ETSI workshop on SDR and CR

10 sd Interactions Operator asks if handset can support the functionality defined in the FDL document Operator Handset MnfDatabase requestconfiguration(fdldocument) requestack requestspm(description) response(spm) calculateconfiguration Handset checks to see if functional blocks are available either locally or in manufacturers database and then if they can be installed with current hardware and functionality install Instruct handset to install new software onto hardware ready for execution. Note: Doesnt stop foreground execution ready requestobject(spm) response(object) install Handset retrieves object code from the manufacturers database and then installs the code into the resources activate(time) execute(time) Operator instructs handset to start executing the new configuration at a given time 10 / ETSI workshop on SDR and CR

11 Long Term Vision Operator defined Radio Access Technology Spectrum De-Regulation Operator allowed to customise standard RAT or produce proprietary RAT Operator will want to configure terminals to optimise Quality of Service and give added value to their customers But operator cannot limit supply of equipment SDR, FDL and associated protocols supports this kind of service. 11 / ETSI workshop on SDR and CR

12 E2RII SDR Proof of Concept Demonstrating how an FDL document can be downloaded from a remote database and used to configure a set of processing resources 12 / ETSI workshop on SDR and CR Equivalent to Transceiver SoC

14 SDR Forum Commercial Working Group Looking at the following: a system for describing the current configuration of a radio and therefore its current functionality, its potential configuration / functionality; the characteristics of current and potential waveforms and Air Interface Standards (AIS s), the type of information being handled and the end users involved.. Currently defining scenarios e.g. Load balancing scenario (WiFi, Cellular, WiMax) Public Safety Scenario Developing a?meta-language? 14 / ETSI workshop on SDR and CR

15 Summary & Conclusion FDL has been developed to communicate functional information around a wireless network FDL is network independent FDL is flexible and scalable to match the evolution of SDR and Cognitive Radio Similar ideas are being investigated in the SDR forum A proof of concept is being developed within E2RII 15 / ETSI workshop on SDR and CR
