E2R II Project End-to-End Reconfigurability - Phase 2 Funding

– 6th Framework Programme of the European Commission second phase of the project started on Jan. 01, 2006 Objective

– “Mobile and wireless systems and platforms beyond 3G”– To devise, develop, trial and showcase architectural design of reconfigura

ble devices Key Challenges of Phase 2

– Enabling sustainable business development of reconfigurable systems in a multi-access/multi-owner environment

– Enabling end-to-end reconfiguration management and control architecture and devising optimal split of intelligence between network elements and end-user equipment

– Enabling efficiency enhancements for radio resource and spectrum management

– Enabling unified stable, secure and reliable reconfigurable connectivity in a multi-access/multi-owner situation

– Building the European reference prototyping environment for end-to-end reconfigurable systems and solutions


Introduction (1/2) Purpose of OMA-DM

– to allow remote device management– to define an appropriate structure and protocol to handle

a vast range of configuration data

Device Management (DM) of OMA-DM– management of the device configuration and other

managed objects (MO) from the point of view of the various Management Authorities


Introduction (2/2) The complexity of technical systems, especially

embedded systems within mobile communication devices, is constantly increasing the parameters, which need to be defined to configure such a device, are tremendously growing

Today’s approach of DM– characterized by an off-line approach

• device is configured at short sessions during which it is connected to a DM server

• most of the time the device is disconnected from the server

• mobile device operate with the provided DM Server settings

– Operator and device manufacturer centric


Problem of existing DM method Assumption of today’s approach

– server can predict all possible condition of device’s environment so that provided configuration handles properly devices

Operator and device manufacturer centric approach is relatively inflexible in unforeseen situation

unforeseen situations might occur more frequently in heterogeneous environment

it has to be doubted that the assumption of today’s approach is true and will be true in future


It appears beneficial to create an improvement to the existing server-tied DM by utilizing autonomic behavior in the device

Key target of autonomic self-optimization approach– to reach at least a good local optimum or maybe even the

actual best possible compromise between contradicting requirements of mobile equipment configuration

• Intuitive presentation of instantaneously available services instead of user guided search

• Cost-optimized network access• Utilization of the available network bandwidth for fast

data communication with low latencies• Power reduction to gain more active run time and

standby time

NG-AUTONOMIC MOBILE DEVICES


Proposed DM method smart policy based scheduling to achieve self-

management and configuration capabilities– allows the client to perform sequential management actions

requested by a DM server without being in a session with that DM server

– a special terminal resident method for the client to perform management actions requested by the server or user at given times or certain conditions

– the server does not need to monitor the status of the device because smart policies, traps and schedules have the capability to alert the device autonomously about certain conditions

– Under a some given condition, reconfiguration is triggered– be implemented in a hierarchical way

• the system may take corrective actions if it can solve the issue. If not, it calls for support from the next upper hierarchy layer or finally from the human operators


Configuration Control Framework The definition of a set of collaborating instances or

modules that are logically located between the DM server and the device’s functional components is needed to implement autonomous device self-DM inside a mobile device

These modules need to take over tasks of communication, observation, data logging and decision making

The configuration control framework for the reconfigurable equipment architecture consists of three types of modules– Configuration Management Module (CMM)– Configuration Control Module (CCM)– Configurable Execution Module (CEM)


CMMreconfiguration related communication

configuration deployment

Negotiate and Select network offers among available

networks


CCMprimary interface between the CMM and the CCM which sets up a new configurat

ion in terms of overall RATs

interface between the CMM and the CCM to supply a set of functions

unique to the selected RAT

provide information, which configuration the underlying layer is able

to surpport

provides access to databases


Conclusion Contribution

– outlined the key-functionality of the Advanced Device self Managing framework

By using the self configuration and management capabilities in addition to OMA DM, proposed reconfiguration architecture may either send to the reconfigurable terminal "Knowledge" on how to behave in certain conditions, or analyze some conditions

Future work– The policy driven autonomic self-configuration extends

the DM server based approach
