Term explanations

Synchronisation• act of making different datstores holding

the same data SyncML

• protocol managing synchronisation c`man (consistec mobile access node)

• synchronisation solution based on SyncML

Symbian• Operating System for

mobile devices

Overview


Parts of synchronisation Software

Main Application including GUI and settings management Communication

• communication media• protocol

Datastore connection• read, store, delete

Sync Monitor; automatic datastore modification detection

Synchronisation Software


Main Application

Requirements• GUI (graphical user interface)• Settings management• Control logic

Programming language: Symbian C++ SDK freely available from Nokia/Symbian• including API

Development on Series 80 device

Synchronisation Software Parts


Communication

Connection to server using the internet• GPRS (GSM)• HSDPA (UMTS)• Wireless LAN

Using ssl encrypted connection Protocol: SyncML Symbian supports https-client API Symbian supports certificate installation



Datastore connection

Symbian C++ API supports PIM

c`man requirement:• modular implementation• easy way to support customer specific datastores

Implementation as plugin• DLL (dynamic linked library)• Loaded at application run time



Sync Monitor

Detects automatically modifications Saves changes for synchronisation Start at boot time Symbian OS does not support autostart Sync-Monitor start by dummy-Recognizer• Recognizer determines MIME-type of files• used by file-manager• Recognizer registers itself at boot time



Sync-Monitor Problems

Problem:Change-Log entries triggered by synchronisation

Solution:Communication between Sync-Application and Sync-Monitor

Problem:Datastore modification during synchronisation

Solution:Change-Log blocking while synchronisation



Conclusion

Implentation of base functionality of a synchronisation software

Faced problems:• Programming language• DLL implementation• Communication support• SyncML support• Sync-Monitor functionality

Base of Symbian support for c´man Framework

Conclusion
