2.2.2.1 LTE New-build solution design Input
Engineering Parameter
Description The LTE new-build solution design module is a very important function to get the new-buildnetwork into the steady operation in a short period. It will design the general strategy of the network and the entire plan for the total new-build network design project. It includes:
Design the LTE interoperability strategy.
Design the LTE multi carrier balancing strategy.
Divide the clusters and draw up the timeline.
Define the final acceptance criteria which include test equipment selection, test route definition, test method definition, statistics and drive test KPI acceptance criteria definition. LTE interworking strategy is a very important design module and it includes idle mode and connected mode design. Idle Mode The GL/LTE/UL multi-mode MS will stay on LTE network when LTE RF signal is above the absolute threshold since LTE network has the high priority. But in the LTE coverage boundary, the MS can be down to GSM network to guarantee the service. Connected Mode The GL/LTE/UL multi-mode MS always sets up RF link for PS call on LTE network when LTE RF signal is above the absolutely threshold. It can be handed down to UMTS network by DRD or Redirection when LTE in high load or poor coverage. It can also re-setup RF link on GSM network by CCO or Reselection when LTE in high load or poor coverage. When the GL/LTE/UL multi-mode MS camps on LTE network, the voice call should be set up on GSM or UMTS network by CSFB. When voice call is finished, the MS will return to LTE network. LTE multi carrier balancing strategy is another important design module and has close relationship with interoperability strategy design. Firstly, the number of carriers for the LTE network should be decided by the future data traffic requirement .Secondly, the different LTE carriers may have big gaps on spectrum and have very different radio propagation performance. So the lower spectrum should be designed as coverage layer and higher spectrum should be designed as capacity layer. Finally, to realize the layer function design and carriers balance, the LTE interworking strategy for both idle mode and connected mode should be considered.

2.2.2.2 LTE New-build cell parameter design Input
Engineering Parameter
Traffic model
Description The LTE new-build cell parameter module will detailed design the cell parameters which includes the numbering and naming for the sites and cells, TA/SA design, intra-frequency, inter-frequency, and inter RAT neighbor list design, PCI design, Logical root sequence design, and the baseline of system parameters which include access related parameters, handover related parameters, timers , and etc.
Numbering and naming design: The Numbering and naming design is to plan the number and name for the eNodeBs and cells.
TA/SA Design: Tracking Area is similar with LA of GSM and UMTS network, but there is a new concept named TA list which includes one or more TAs. It is the real paging area, the paging messages from the network to the UE are sent in all the cells of TA list.
Neighbor Relation Design: Define the neighbor relations, including intra-RAT and inter-RAT neighbors. Huawei professional planning tool can out put all of those neighbors automatically, to simply the planning process and minimize the possible mistakes.
System Parameter Design: The system parameters design includes the access related parameters design, handover related parameters design, timers design, and etc.
PCI design: PCI is a very important parameter using to identify a cell. It is similar with PSC in UMTS network. Huawei recommend U-NET V3R6 is used to do the PCI planning.
Logical root sequence design: Logical root sequence is an important parameter which will affect the performance of access phase.
2.2.3 LTE Network Initial Tuning Description Network cluster initial tuning is necessary for new build service. It includes three sub-modules: radio network audit, single site verification, RF cluster tuning.

2.2.3.1 LTE Radio Network Audit Input
LTE engineering table
eNodeB configuration file
Traffic statistic file
Description Radio network routine audit helps to find and exclude network performance fluctuation caused by hardware fault and basic configuration problems, such as alarm, missing & redundancy neighbor, PCI/PRACH and parameter configuration error etc. It will ensure the status health of radio network. It mainly includes the following contents:
Alarm checking refers to outputting classified alarm lists according to the impact eNodeB alarms on services (call drop, access, throughput ) and the impact extent.
Neighbor cell/PCI/PRACH check: missing neighbor cell check and redundancy neighbor cell check, special for the cell without any neighbor or missing co-site neighbor. Inconsistency check for neighbor cell information should be included also. Frequency should be checked for consistency with planning.
Parameter baseline comparison: compare the global and cell parameters of the network with the baseline parameters, mark the parameters with obviously improper values and those with large differences, explain possible causes and impacts, and make suggestions on the parameters that need to be optimized.
Huawei suggests performing the routine audit action periodically, the principle of the audit should be agreed with CLARO at the beginning of the project.
2.2.3.2 LTE Single Site Verification Input Integrated site list Cell planning report and site database
Description This service is an activity of evaluation and verification for new eNodeB after site integration, through detailed service item verification, the problems caused by hardware faulty or installation mistake can be found out, special for transmission potential problems, it also can improve the efficiency of network tuning.
Page 13 of 24
LTE New-build RF Service Proposal
During single site verification, do the following: A checklist shall be filled Cell configuration shall be audited both in field Cross-cabling shall be checked and corrected Function and coverage verified with design results Change proposal may be submitted for verification or implementation. At the end of single site verification, a report will be produced; Troubleshooting history of hardware faulty and sites status will be recorded.
2.2.3.3 LTE RF Tuning Input Integrated site list Project parameter table Cell planning report and site database
Description After LTE integration, we need ensure that the coverage performance of radio network is satisfied with the required target and ready for commercial launch, so RF tuning service should be imperative in Huawei service package. According to the both agreed cluster division with customer, make detailed test schedule, design test route, and update sites information. Using DT tool to record radio air interface data, and save the log file, then analyse the network problem such as coverage, handover and call drop, etc. RF tuning is just for new sites, considering the efficiency of work, Huawei suggest it begins when site integration finishes 80% of the entire cluster in one cluster and thus goes on in parallel with site integration, exceptional or single new site’s initial tuning will be considered as site level, Any problems related to missing sites (coverage problem) will be justified by Huawei and the acceptance will be granted by CLARO. The most important items of LTE RF tuning are as below: Pilot coverage analysis Pilot coverage analysis is very important to LTE radio network performance. Weak coverage, over shooting problems are the main considerations of RF optimization. The coverage can be improved by RF Parameter tuning and optimization such as azimuth, tilt and height. neighbor relations optimization Neighboring cell optimization involves adding and deleting neighboring cells. The influence of missing neighboring cells is that the user cannot switch to a cell with strong signal in time, resulting in increased interference, reduced throughput, and even call drop. In this case, it is required to add a necessary neighboring cell. The influence of a redundant neighboring cell is generation of an excessive amount of neighboring cell messages, increase of unnecessary signaling overhead, and failure to add a required neighboring cell when neighboring cells are all configured. In this case, it is required to delete redundant neighboring cells.

DT KPI Optimization The target of RF tuning is to guarantee the service, so the accessibility, mobility, retainability and latency KPI for PS services should match the design target after the optimization. We can modify RF parameters and other wireless parameters to improve the DT KPI.

KPI, any data of cells from both coverage edge and isolated sites shall be eliminated. 5. The KPIs definition, measurement counters, test route, test equipment and test methodology as well as test time for KPIs shall be negotiated and agreed upon both parties. 6. Network performance is affected by the settings of system parameters, so Huawei shall have authorization to configure and optimize system parameters.
4.3 Acceptance Process The LTE new-build is performed per cluster basis, so that the radio network acceptance should be performed per cluster also, only special cases if there is, can be consider exceptional acceptance base on site, if in case no continuous coverage and/or no neighboring sites for the same technology. Huawei can initiate the acceptance after more than 80% sites of the testing cluster and all the VIP sites are finished with new-build, for the Final Acceptance of the cluster or site if apply, will be performed with the 100% sites on air (cluster or site, depend of the previous agreement by both parts). There are two methods for KPI measurements: Field test (Drive Test) and OSS statistics. For exceptional or single new site’s initial tuning service will be considered as site level and Drive Test measurement. The acceptance for the Initial Tuning Services will not mixed with the acceptance of another services, and also it will be considered one acceptance for each different services. Cluster means a group of sites (Normally 10-15 sites) which are geographically neighboring. The actual site number of each cluster should be flexible to allow a fast rollout and acceptance. The cluster definition and drive test route will be planned in advance and mutually agreed by both parties. The following principles can be considered for cluster division: Refer to customer network maintenance distribution in dividing clusters. A cluster should cover the continuous service area. Landform factor affects signal propagation, so it should be considered for cluster division. A cell-like cluster is preferred rather than a strip-like cluster. Administrative areas. DT workload The following principles can be considered for DT route definition: The DT acceptance route should cover major streets, important locations and VIP/VIC area.
