Business Case
Improve DCR KPI by 30% compared to current implementation.
CMCC has set DCR KPI targets for next autumn, so proposed schedule is only viable.
Pipeline impact, risks
Low risk, changes only in ABI.
Request source: CMCC
Original target release: RG10 (BSS)

Feature Overview
• Category: Radio Network Performance
• Issue– Current implementation is not effective enough, thus DCR KPI is not improved
as much as with BR implementation.
• Description:– The existing KPI improvement, BSS101467 Clear Request Suppression is
further improved by suppressing all clear requests after "disconnect" -state.
• References: – Focal Point
– S14 CR: EDS14_060
– S15 CR: EPS15_026
– S16 CR: CR013
• Operability: No
• System Impact: No

Customer Business Case
• Not real biz case, but maybe bit less optimization OPEX when KPI just looks better.

NSN Business Plan: Justification and Timing
• NSN business logic– DCR can be improved.
• Negative impact analysis:– DCR KPI target of CMCC can nor be met.
• Feature market potential:
• Latest Release required by the customer:– RG10(BSS)
• Selling window:

NSN Business Plan: Pricing
• Pricing model– BSW/ASW: ASW– Licence Control in Network Element: Trust based– Licence Control Attributes: N/A– Licence Capacity Info: N/A
• Price range: < Low (25 - 100 eur/cell)
• With the estimated value, market potential and cost, is it feasible to price the feature so that NSN business case will be positive? < Yes/No/NA >

NSN Business Plan: Cost
• Work effort estimates on network elements (including FS, IS, MI, MT, FT)
• Work efforts prepared by <PPO / R&D Program> based on < feature description or more detailed material
• < Product costs, e.g. HW costs, laboratory or production investments >
For the proposals before P0 accurate effort is not required.Following categorization can be used: minor (<150h), low (<500h), medium (<2000h), high
