White Paper W950

Preliminary version - PA4

Key features of symbian OS v9.1:

General:

•Improved system performance, especially at start up.

•New multimedia framework supporting record- ing, playback and streaming.

•Direct access to screen and keyboard gives high performance; graphics accelerator API; and increased UI flexibility (support for multiple simultaneous display, multiple display sizes and multiple display orientation).

•Java™ support for the latest wireless Java stan- dards. See “Java™” on page 47 for more details.

•Communications protocols using; Wide area networking stacks including TCP/IP (dual mode IPv4/v6) and IPSec. Improved personal area networking support including infrared (IrDA), Bluetooth™ connectivity and the introduction of USB. Support is also provided for multihoming and link layer Quality-of-Service (QoS) on GPRS and UMTS networks.

•Symbian OS v9.1 is ready for the 3G market with support for: WCDMA (3GPP R4); GSM cir- cuit switched voice and data (CSD); packet- based data (GPRS); SIM;ternaland U-SIM.

•Supports the Unicode Standard version 3.0.

•Data synchronization has been improved to cover the following: over-the-air (OTA) synchro- nization support using OMA standards (OMADS 1.2); PC-based synchronization over, Bluetooth connectivity, infrared and USB; a PC Connectiv-

ity suite providing the ability to transfer files and synchronize PIM data.n

•Improved device management which provides network operatorsIand enterprises with new capabilities to manage phones in the field. This includesorOMA DM 1.1.2 support and OMA client provisioning 1.1.

•Support for Bluetooth wireless technology eSCOFand Bluetooth stereo headset profiles have been implemented.

Security:

The aims of the security developments in Symbian OS v9.1 are to protect the integrity of the phone, provide extra control over user billable events and to prevent malicious software corrupting executables and data. The aims have been met by:

• Providing platform security by a proactive system defence mechanism based on granting and monitoring application capabilities through Symbian Signed certification. The infrastructure allows applications to have private protected data stores.

• A proactive defence mechanism against mal- ware. The platform security infrastructure uses a capability based model which ensures that sen-

sitive operations, such as, modifying user data,

 

y

making calls and using network connections,

l

can only be accessed by applications which

On

 

have been certified by an appropriate signing authority.

• Data caging; this allows applications to have their own private data protection. This allows applications a guaranteed secure data source. Thisecan be used for applications, such as, ecommerce. An application can access other sdirectories marked as open but cannot access another application’s private directory.

U• Additional platform security includes; full encryption and certificate management, secure protocols (HTTPS, SSL and TLS) and WIM framework.

EKA2 Kernel:

•A new realtime kernel (EKA2) with guaranteed response times provides the basis for a robust and power-efficient phone. Predictable real time operation means that the OS will respond to interrupts, system and user threads within a known period. This means that no task in the system can prevent the OS from responding to key tasks.

•Support for multiple simultaneous IP connec- tions.

Development and testing:

•Provides new customization and configurability options for the operating system.

•Symbian OS is built using the ARM RVCT 2.1 compiler. This compiler is compliant with the ARM EABI standard. This allows compatibility with the latest ARM compilers and reduces the Symbian OS footprint while enhancing perfor-

mance.
