What Client Needed
A large network operator was assigning primary scrambling codes (PSCs) for each base station during integration. SON module did code reallocation upon PSC clash. Client recognised that this approach of allocating codes one by one is limited because for each base station there were only a few good code candidates.
What We Did
We created OptiCode: a tool for code allocation (PSC and PCI) in telecom networks:
- Replans code assignment for entire network at once (tested on biggest metropolitan areas in the world).
- Flexible to accommodate network design rules (code pools, border areas, +8 rule, etc.).
- Industry best results: cleans-up code clashes on 4 tiers and 6km in metropolitan areas.
How Did Client Benefit
PSC reallocation was done for the entire region (with 2 vendors) at once. Simulation lasted less than 24 hours, with overnight implementation. All clashes on tiers 2 and 3, together with most of the clashes on tier 4 were cleaned up. Targeted KPIs significantly improved as a direct result.
