Objective

• To have the optimum number of ADJS/ ADJI/ ADJG of 3G
  network both in F1 and F2.
• To optimize the 3G coverage in both layers. This can help to
     –     Clean up Pilot Pollution,
     –     Reduce Overshooting
     –     Increase Cell Capacity
     –     Reduce the possibility of SC conflict.

Scope

• Optimisation will be done for 2nd carrier cluster only. This may
      have to include sites outside the cluster that affect the
      performance of sites in the cluster.

Network Design Scenario
Connected Mode Strategy (Macro)

• Inter frequency handover adjacency is defined oneway F2 -> F1 to
  ensure mobility (except for colocated site, IFHO F1 -> F2 must be
  defined only for HSDPA to make sure HSPA Capability Handover)
• ADJG from F2 on 3G-2G border to ensure mobility. One-Way
  From F2  2G Only
                                                                   F2 Border

        This could be used as an indicator for cells with having
        improper coverage footprint (Overshoot).


        We may plot the MAX PRACH Delay Class on Mapinfo for better
        visualization of coverage footprint of cells in our cluster. (See

                                                                                         1/2/3 can be
1. Start with ADJx Deletion. F1 and F2 (Autodef 7-days Data)                             executed at the
2. Delete ADJI F1 F2 for Non-Collocated Site, if any                                    same night.
3. Create ADJI F1<--> F2 for Collocated Site (like Page 5)

4. ADJS Addition in each Layer.(Autodef 7-days Data)
           F1 <-> F1
           F2 <-> F2
            ADJS addition MUST be done before ADJI and ADJG addition. Good ADJS planning can
            significantly reduce interference, as a result number of required ADJG and AGJI will also decrease.
5. ADJI Addition. (Autodef 3-5 days Data)
         F1 <-> F2
         F2 <-> F1
         Again, well planned for ADJI will reduce Number of ADJG neighbors
6. ADJG Addition (Autodef 3-5 days Data)
          F2  2G
          F1  2G


                At the end, we also expect to see number of ADJG from:

                                      F2  GSM        <     F1  GSM

SIB11 Planning

•    IF ADJS+ADJG+ADJI <= 47, Set ADJx = SIB11(1) for all ADJx
•    IF ADJS+ADJG+ADJI > 47,
     – For F1
       Set ADJx = SIB11(1) for (all ADJS + main ADJI + main ADJG) <= 47
       Set ADJx = SIBbis(2) for the “Remaining” ADJI and ADJG.
     – For F2
       Set ADJx = SIB11(1) for (main ADJS + all ADJI + main ADJG) <= 47
       Set ADJx = SIBbis(2) for the “Remaining” ADJG and ADJS.


• IF Overshooting case,
           Set ADJx = Not Broadcast (0).
           [This is not to allow UE camping on cells that very far away and later the
             ADJx will be deleted anyway, when downtilt done]




Soc Classification level

End Results

• In general case, Final combined Neighbour (Adjs+Adjg+Adji)
  <= 36 Neighbours
• Try NOT to use SIB11bis, or use it as less as possible.
• No Cell blocking Alarm due to Too many neighbors (Alarm
  ID_7771)
• Provide Antenna Downtilting List to Customer.

Optimisation guide line ver1.1

  • 1. Guideline Neighbor Optimization and Pilot Pollution Cleaning Version 1.1 Soc Classification level 1 © Nokia Siemens Networks Presentation / Author / Date
  • 2. Objective • To have the optimum number of ADJS/ ADJI/ ADJG of 3G network both in F1 and F2. • To optimize the 3G coverage in both layers. This can help to – Clean up Pilot Pollution, – Reduce Overshooting – Increase Cell Capacity – Reduce the possibility of SC conflict. Soc Classification level 2 © Nokia Siemens Networks
  • 3. Scope • Optimisation will be done for 2nd carrier cluster only. This may have to include sites outside the cluster that affect the performance of sites in the cluster. Soc Classification level 3 © Nokia Siemens Networks
  • 4. Network Design Scenario Connected Mode Strategy (Macro) • Inter frequency handover adjacency is defined oneway F2 -> F1 to ensure mobility (except for colocated site, IFHO F1 -> F2 must be defined only for HSDPA to make sure HSPA Capability Handover) • ADJG from F2 on 3G-2G border to ensure mobility. One-Way From F2  2G Only F2 Border F2: HSDPA+R99 F1: R99 HS+R99 2G Soc Classification level 4 © Nokia Siemens Networks Presentation / Author / Date
  • 5. Network Design Scenario Connected Mode Strategy (Site-Level) Zoom In Below ADJI Strategic is ideally used for Capability Based Handover. Figure shows How to define ADJI in one site. F2: HSDPA+R99 F1: R99 S1 S2 S3 Soc Classification level 5 © Nokia Siemens Networks
  • 6. Methodology • Neighbour Optimisation – Deletion – Addition • Coverage Optimisaton (Tilting) Data and Tools • OSS Data – Autodef (RSRAN044/ RSRAN045/ RSRAN046) – PRACH Delay Class 0-20 (M1006C128 – C148) – SHO Overhead (RSRAN028) (optional) • PE Dump ( To get actual ADJx) • Site Location Info ( To get Latitude/ Longitude) • MapInfo ( To have visualize for neighbor planning) • Planning Tool to calculate Antenna Tilting Soc Classification level 6 © Nokia Siemens Networks
  • 7. Propagation Distance Mapping Table Our Parameter Setting for Propagation Cell Range is: PRACHDelayRange = 3 (20 km) Soc Classification level 7 © Nokia Siemens Networks
  • 8. Propagation Distance Distribution Value can be changed depend on cluster environment 205 Cells in UPD3 is having propagation distance farer than 7 km. Need to carefully visualize on Mapinfo for downtilt decisions. Soc Classification level 8 © Nokia Siemens Networks
  • 9. Propagation Distance list This is an example PRACH Delay Class from OSS. (7 days data) Microsoft Excel Worksheet This could be used as an indicator for cells with having improper coverage footprint (Overshoot). We may plot the MAX PRACH Delay Class on Mapinfo for better visualization of coverage footprint of cells in our cluster. (See Next Slide) Soc Classification level 9 © Nokia Siemens Networks
  • 10. Propagation Delay Plot on MapInfo Missing ADJS detected by Autodef Overshooting detected by Autodef+ PRACH Delay From Propagation Delay on Mapinfo, we can get an insight of How coverage propagation look like. Soc Classification level 10 © Nokia Siemens Networks
  • 11. Neighbour Deletion Diagram Distance can be changed according to environment Value can be changed depend on traffic density in each cluster. Adjs/Adji/Adjg respectively Use Autodef Data for last 7 days, Aggregate “Whole Period” Soc Classification level 11 © Nokia Siemens Networks
  • 12. Neighbour Addition Diagram Value can be changed depend on traffic density in each cluster. Adjs/Adji/Adjg respectively Use Autodef Data for last 7 days, Aggregate “Whole Period” Soc Classification level 12 © Nokia Siemens Networks
  • 13. Optimisation Sequence 1/2/3 can be 1. Start with ADJx Deletion. F1 and F2 (Autodef 7-days Data) executed at the 2. Delete ADJI F1 F2 for Non-Collocated Site, if any same night. 3. Create ADJI F1<--> F2 for Collocated Site (like Page 5) 4. ADJS Addition in each Layer.(Autodef 7-days Data) F1 <-> F1 F2 <-> F2 ADJS addition MUST be done before ADJI and ADJG addition. Good ADJS planning can significantly reduce interference, as a result number of required ADJG and AGJI will also decrease. 5. ADJI Addition. (Autodef 3-5 days Data) F1 <-> F2 F2 <-> F1 Again, well planned for ADJI will reduce Number of ADJG neighbors 6. ADJG Addition (Autodef 3-5 days Data) F2  2G F1  2G At the end, we also expect to see number of ADJG from: F2  GSM < F1  GSM Soc Classification level **F2  GSM (for F2 Border) 13 © Nokia Siemens Networks
  • 14. SIB11 Planning • IF ADJS+ADJG+ADJI <= 47, Set ADJx = SIB11(1) for all ADJx • IF ADJS+ADJG+ADJI > 47, – For F1 Set ADJx = SIB11(1) for (all ADJS + main ADJI + main ADJG) <= 47 Set ADJx = SIBbis(2) for the “Remaining” ADJI and ADJG. – For F2 Set ADJx = SIB11(1) for (main ADJS + all ADJI + main ADJG) <= 47 Set ADJx = SIBbis(2) for the “Remaining” ADJG and ADJS. • IF Overshooting case, Set ADJx = Not Broadcast (0). [This is not to allow UE camping on cells that very far away and later the ADJx will be deleted anyway, when downtilt done] Soc Classification level 14 © Nokia Siemens Networks
  • 15. End Results • In general case, Final combined Neighbour (Adjs+Adjg+Adji) <= 36 Neighbours • Try NOT to use SIB11bis, or use it as less as possible. • No Cell blocking Alarm due to Too many neighbors (Alarm ID_7771) • Provide Antenna Downtilting List to Customer.
