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 >

– < Comments related to pricing and price level >


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
