Device ManagementDefinition– A tool to alleviate operators’ and end-users’ problems and

consequently improve product and service perceived qualityand end-user satisfaction

Problem [2]– Device usability characteristics– Increased terminal complexities– Increased numbers of mobile devices– Increased stratification of the value-chain– Early adoption

Goal– Protect Network Resources– Protect Early Investments– Minimize the cost of service delivery– Facilitate Device Usability


Device Management

From : Nokia Device Management white paper [3]


Device management means...For the end-users For operators and service providers

”These new products and services are so easy to use.””If I have a problem, my operator can find and solve the situation for me.””It is easy to get new services to work in my terminal.””Now, I can focus on using the services, not configuring them.”

”We can – identify, diagnose, and remedy

end-users’ problems before they even notice them

– provision and troubleshoot new services remotely.”

”We benefit via– cost savings in customer care– increased revenues from new service

s – reduced churning due to service qual

ity.”

• Device management is an enabling feature for the operators and service providers

• End-users see it as superior product and service quality

Open device management (DM) technologyframework

DM architecture (OMA) is based on trusted relationship between management serverand client to be managedIn practice, DM has two logical parts:

– bootstrapping to establish the relationshipand insert basic parameters forout-of-the-box experience

– continuous management for actual value-added management operations (problem identification, configuration management)

Two viable technology solutions enabling DM– WAP Forum provisioning for bootstrapping– SyncML DM for continuous management

Standardization and technology status

Provisioning specifications are publicBootstrapping is defined

– limited parameter support– specification is extensible

Continuous provision technologyis not defined, use cases and requirements exist

1.1 specifications approvedin April 2002Interoperability requirements in processSyncML DM is to be included in SyncML interoperability process

Autonomic Computing[1]Autonomic– Pertaining to operating system that responds automatically to

problems or system failures.

Autonomic computing [7] [8] [9]– A computing environment with the ability to manage itself and

dynamically adapt to change in accordance with business policiesand objectives.

– Application of technology to manage technology and reduce need for human intervention

– Proposed by IBM to provide the enterprise with agility & speed to respond to any customer demand, market opportunity or external threat


Autonomic Computing Attributes

Increased ResponsivenessAdapt to dynamically changing environments

Business ResiliencyDiscover, diagnose,

and act to prevent disruptions

OperationalEfficiencyTune resources and balance workloads to maximize use of IT resources

Secure Information and Resources

Anticipate, detect, identify, and

protect against attacks

Multiple Layers of Autonomy

Multiple autonomic managers for multiple resources

– Autonomic managers are arranged in hierarchical fashion

– Lower-level managers deal with resources at smaller granularity and/or smaller locality

Top-level autonomic manager:– Business decision-making– Policy and service levels

Service ControlSession Control functionality provides generic procedures:– to establish, maintain, modify

and terminate sessions– interactions between

controlling parties and resources

– not service specific and hold for a large number of services.

Complexity– Need to manage modules

hierarchically to maintain the established session
