Michael Möhlenhof T-Mobil;Systemtechnology page:1 T-Mobil Germany From Voic to Unified Messaging Concepts Presentation at the VMA Conference Vienna, Austria

Michael Möhlenhof T-Mobil;Systemtechnology page:2 T-Mobil Germany T-Mobil Network 100% subsidiary of the Deutsche Telekom AG T-D1 (GSM) More than 12 million active subscribers T-D1 Mobilbox Pre-Paid and Post-Paid versions Fix-mobile conversion product

Michael Möhlenhof T-Mobil;Systemtechnology page:3 T-D1-Mobilbox Main Voic Product T-D1 Mobilbox for every customer Calls to/from Voic generate revenue Highly reliable service and a good quality reached Well accepted in the market Heavy investment for hardware and software in the past

Michael Möhlenhof T-Mobil;Systemtechnology page:4 New fundamental Voic Services are not visible What is the next stage of communication? Where are we going to?  Combine Voic and Message to Unified Messaging Service create a Unified Messaging Box (UMB)

Michael Möhlenhof T-Mobil;Systemtechnology page:5 Keep in mind ! Save the operators investment Save the reliability Add a new dimension to voice messaging, but keep the customer‘s telephony interface Every thing new?

Michael Möhlenhof T-Mobil;Systemtechnology page:6 Parts of UMB Solution ? SS/ISUP VMS EMS IP/Internet

Michael Möhlenhof T-Mobil;Systemtechnology page:7 Typical login time to server is 7 to 30 sec The.com world will accept this Nobody will accept such a delay on a telephone interface Voic Message and status information (e.g. you have „n“ new Voic s and „m“ s incl. header information) must be presented without any delay Customer Expectations I

Michael Möhlenhof T-Mobil;Systemtechnology page:8 No customer likes to change his telephone number or his address Subscriber will expect well known intelligent notification schemes for all types of messages Customer Expectations II

Michael Möhlenhof T-Mobil;Systemtechnology page:9 Messages will be primarily accessed via the appropriate interfaces Voicemessages at the telephone as speech Faxmessages with a fax machine s with an Client (Computer), Web Mail To reduce the traffic between systems keep messages local until requested on other media Assumption for UMB product I

Michael Möhlenhof T-Mobil;Systemtechnology page:10 Added value is generated by interworking functions as Listen to s when on the move Collecting voic s when online (less important) Unified overview over all messages received Assumption for UMB product II

Michael Möhlenhof T-Mobil;Systemtechnology page:11 Existing features at the Voice interface must be available for the customer Examples: „Notification Engine“ HLR-Interrogation before Outcall notification (smart notification) Automatic identification of the customer by CLI Existing user interface Assumption for UMB product III

Michael Möhlenhof T-Mobil;Systemtechnology page:12 EMC: Enhanced Message Collector Flexible interface between Voic and systems Interfaces three systems: Voic system storage (EMS) Large directory engine (LDE) Technical solution: EMC

Michael Möhlenhof T-Mobil;Systemtechnology page:13 All parts of the concept should be based on open standards A candidate could be IMAP 4 for interfacing VMS/EMS POP3 may be used instead but raises some security problem does not allow for intelligent management of the message box LDE accessed by LDAP (X.500) EMC: Open Interfaces

Michael Möhlenhof T-Mobil;Systemtechnology page:14 Architecture EMC Concept EMS IP/Internet SS/ISUP VMS EMC Enhanced Message Collector WAP- Proxy WEB- Portal Large directory engine Adminstration- Systems

Michael Möhlenhof T-Mobil;Systemtechnology page:15 Internal routing of messages Transmission of s to a text to speech engine at the VMS Transmission and conversion of Voic to Systems in standard audio format like *.wav) Telefax conversion to *.tif Initialization of the notification functions of the VMS EMC Interfaces via IMAP4:

Michael Möhlenhof T-Mobil;Systemtechnology page:16 Large Directory Engine used for Administration interface Special secured storage of Log-ins for EMS and VMS Customer address book etc. Note: Password entrance of EMS defined by ISP VMS Entrance secured by CLI / SIM or password Large Directory Engine:

Michael Möhlenhof T-Mobil;Systemtechnology page:17 All telephone operators have a voic system Development of new VMS Services fades out Investments should be saved Go internet Summary My mission: Bind the worlds use EMC concept
