Security and mobility
management in the Embedded Internet
University Paris 6
Abstract: This tutorial investigates the technology and
architectures that will be needed for mobility "in the large",
enabling millions of users to connect anytime to thousands of enterprise,
public, home wireless networks, with handhelds or laptops, with the guarantee
of global security and seamless access to applications. We will begin by an
overview on the different characteristics of the wireless access networks (IEEE
802.11, 802.15, 802.16, 802.20).
The first issue treated in this tutorial relates to network/user mutual authentication, radio link privacy (encryption), non repudiation (signature) and data integrity. The second issue concerns mobility management that is defining and enforcing corporate mobility policies: who can use what from where, and under which constraints. Mobility management addresses fine grain access control, quality of services and seamless access.
A general solution using a smartcard and a filter will be detailed: once the user is authenticated, the applicable access rights and mobility policies are read and compiled on the filter. Each packet sent is signed by user, filtered and checked against rights and policies. Illegal packets are removed. In case of bandwidth conflicts, packet flows are prioritized against others. When packets target an unavailable service, mobility manager sends an alert to the seamless service layer.

LANOMS 2003 Tutorial II
Management for Next Generation of Wireless Networks and Services
Manhattan College, New York, USA
Abstract: Next generation wireless networks and services will be drastically more complex than today's so called second-generation (2G, 2.5G) wireless systems and wireless LANs. New wireless architectures will include not only 3G and 4G systems, but also high capacity pico cells, urban microcells, wireless ad hoc and sensor networks, wide area macro and increasingly popular Wireless Local Area networks interconnected, as well as satellite networks. IP and Internet will play a key role in these wireless networks. Not only the networks elements, communication devices will be evolved but so will the management systems and way of managing.
This tutorial will start with an overview of the present and future wireless communications networks and services. A review of the current network
management practices and technologies used for today's wireless networks will be provided next. Then, the tutorial will introduce the current standardization and industry activities related to network management for future wireless networks and services. The tutorial will conclude with a discussion of the current research activities in this area.

Over-the-Air Device Management

Abstract: As the functionality of mobile devices grows at an increasing rate, configuring and maintaining mobile applications and services becomes a complex and time-consuming task. For instance, enabling WAP, GPRS, CDMA, and data connectivity requires configuration of multiple settings. Even with limited features of today, many customers find it difficult to configure their mobile devices. Operators should ensure that phone configuration is quick and easy for the customer. Another use case is over-the-air (OTA) provisioning and management of services in mobile devices. Advanced mobile services such as browsing, multimedia messaging, mobile e-mail, and calendar synchronization requires accurate mobile phone settings. The process of remotely managing device settings and applications is called Device Management.
An OTA mechanism for Device Management removes the burden of configuration and trouble shooting from end users of mobile devices. User no longer needs to change the mobile device or go to a physical location of the service provider to subscribe to services of interest. For the service providers, this reduces the cost and complexity of provisioning services and ensuring quality of service (QoS) through management. OTA Device Management will help the widespread adoption of mobile services, as it provides a mechanism for the users to easily subscribe to new services. For wireless network operators and service providers, this enables a fast and easy way to introduce new services, as well as manage provisioned services by dynamically adjusting to network changes.
An industry forum, namely SyncML Initiative, has developed open standards for OTA Device Management, called SyncML Device Management (SyncML DM). On November 1, 2002, the SyncML Initiative was consolidated with the Open Mobile Alliance (OMA), which is a global alliance of industries. The Open Mobile Alliance aims to develop open standards for enabling subscribers to use interoperable mobile services across markets, operators and mobile terminals. Such an open framework will help applications and services to be built, deployed and managed efficiently and reliably in a multi-vendor environment. The OMA Device Management (OMA DM) working group within OMA was formed by consolidating SyncML DM and WAP Client Provisioning activities. OMA DM group will continue to develop open standards for future mobile requirements.
In addition, the third generation partnership project 2 (3GPP2), which develops 3G radio and network standards based on cdma2000 systems, published standards on OTA provisioning, and IP based methods for OTA management.
The tutorial will introduce OTA device management and then discuss legacy (2G) methods for OTA service provisioning (OTASP) and parameter administration (OTAPA) in cdma2000 systems. In CDMA, legacy standards define the use of data burst messages for OTASP and OTAPA. The session will explore the evolution of 3G standards, especially IP based methods for OTA management and the technical specifications from CDMA Development group (CDG), which was standardized in 3GPP2. The tutorial will cover in detail the OMA DM technology. Finally, future standardization activities related to OTA management in OMA, 3GPP2 and 3GPP would be discussed. The tutorial will be presented in following parts.
