1 Wireless Device Management: OSS for Leading-Edge Wireless Rakesh Kushwaha, CTO mformation Technologies HOTOP4 Wednesday, October 13, 2:00-3:00 pm

2 Topics: Wireless Devices & Device Management server (DMS) Current Service Management Landscape How DMS (as an OSS) Can Help Current Industry Initiatives Around DMS Where DMS Fits in the Architecture How DMS enables Automatic Service Delivery and Captures Novel & Nifty Service Quality Indicators Case Studies 2

3 Definitions Wireless Edge Device Wireless terminal used by end subscriber, always connected to a wireless voice and packet network, and capable of delivering voice and data applications (Wireless devices operating on 2.5/3G networks) Device Management System (DMS) An operation support system (OSS) capable of interacting with set of wireless edge devices for the purpose of device management, including functions in the areas of Configuration Management, Software Management, Fault/Performance/QOS Management, and Billing 3

6 How DMS Can Help Allows service provisioning and activation at the customer s device Provides visibility and control of service quality delivered to end customers Provides simple indication of service performance as proactive element to support existing management systems Single source of reliable information on customer service availability and performance Allows maintenance of hardware/software inventory for devices Service level expectations can be realistically set against known benchmarked information on service availability and performance Automating service activation and knowing what the customer feels is key to driving up customer satisfaction and reducing customer churn 6

7 Current Industry Initiatives around DMS OMA ( OMA DM (device management) WG (working group) has defined requirements for remote management of devices Initial focus on configuration management and software management (provisioning and activation) Fault and performance management are part of the requirements OTA communication is based on the SyncML protocol Web services interface is the preferred interface for exchanging data with other systems Contribution-driven ETSI/3gpp ( Defines architecture for end-to-end service management (ETSI TS ) Defines performance measurements for the 3G data networks (ETSI TS version Release 5) 7

12 Case Study 1 3G Service Provider Environment UMTS wireless operator Devices: 3G Handsets, UMTS SIM cards Primary applications: Voice calls, MMS, IP-based services Solution set deployed QOS monitoring from edge user device Policy-based QOS service monitoring Device provides measurements for estimating service available at various geographical locations Data provides hole in the data coverage Allows build out of the network Provides reports to higher management Exports data to other network management systems 12

13 Case Study 2 GSM Service Provider Environment GPRS/GSM Wireless operator Devices: Smart phones (Symbian, Microsoft OS) Primary applications: Corporate , IP-based services Solution set deployed Service Activation on edge user device Application deployment on the smart phones GPRS and application settings on the device Automating service delivery Provides diagnostics capabilities for Customer Care Enables corporate Help Desk to manage devices 13
