3 Content Requirements and Expectations. Telecommunications Network Management (TMN) Theory and Reality Pressures for change: causes and results Questions

4 Service Expectations Connection Activation Outage Block, Drop, Rate Pricing Revenue collection Wire-line Cellular Data Wire-line Cellular Data 2 days to 5 years Few minutes per year(5/9 s) Minutes (no physical install) Few minutes per month? Minutes (no physical install) Several hours per month Rare Common (x 100?) Very variable - Time & distance - Some discounts Printed bill Internet a/c - Time, distance, roaming - Many discounts & packages Pre-paid Printed bill - Fixed recurring - Usage independent - Viewable on line By credit card

5 Delivery Promises To Financier: promised profit. To end customer:- service activation in promised time the contracted services at the contracted price robust and dependable.five 9 s? problems fixed in promised time billing accurately, understandably, responsive.

6 Make a Profit: It s easy! Profit = Income - Costs (and some tax!) Income 4No. of Customers *Revenue/Customer 4Interconnection charges & Transit Traffic Costs: 4Network: Equipment and build 4Support & Facilities: IT, Planning, Buildings 4Sales & Operations: People, Processes, Systems (BSS/OSS) 4Interconnection costs.

7 Operations Means Test An organisation should be able to positively answer four basic questions regarding any service it wishes to offer. Do we have the Means to Sell This Product or Service? Do we have the Means to Activate This product or Service? Do we have the Means to Bill for This Product or Service? Do we have the Means to Maintain This Product or Service?

26 Number Portability Problems Political Will Corporate Will Data base administration Corporate information mismatch Port Information mismatch Finger trouble!

27 Pressure for change: Services and Technology Customers Small Large Residential business business Voice, Mobility, Cable, Data & Internet Services Discrete Networks Data Wire Cable Radio Service & Applications IP Packet networks - Circuit switched voice - Voice band data, lease line etc. Bottleneck - Always connected - Wide-band - Data and Voice Service Enabler Access

28 Pressure for Change: Enterprise Model Customer domain Customer Provider domain =Business Relationsship Retailer Retailer Service relationsship Service Service Provider Consumer Connectivity relationsship Connectivity Provider

29 Summary Theory and Reality are rather different! Things are set to become more complicated in: 4Types of Network Equipment and rate of change 4Less standardisation Increasing demand for: 4Instant response (activation, billing etc) 4Multiple services, single managed infrastructure 4Customer Self Care. Forward planning is everything Despite the technological wonders, the most common problems - and the most difficult to solve - are interfaces and finger troubles.
