Nayeemul Hasan, Md. Even if more realistic values of SE could be obtained from simulations, these cannot capture all possible factors, which greatly vary from cell to cell and dynamically change with time. As a result, SE and throughput measurements are much lower than expected in live networks [ 28 ]. Network planning is negatively affected by the overestimation of SE, as this parameter controls the expected demand of network resources.

Thus, underestimating the average cell load during network coverage planning might lead to a too optimistic cell radius from unreal cell-edge performance. Likewise, underestimating cell load might give an inadequate amount of the traffic resources needed per cell during network capacity planning. Connection Traces Data for managing a radio access network includes a Configuration Management data CM , consisting of current network parameter settings, b Performance Management data PM , consisting of counters reflecting the number of times some event has happened per network element and Reporting Output Period ROP , c Data Trace Files DTFs , consisting of multiple records known as events with radio related measurements stored when some event occurs for a single User Equipment UE or a base station.

UETRs are used to single out a specific user, while CTRs are used to monitor cell performance by monitoring all or a random subset of anonymous connections [ 30 ].

The former are used for network troubleshooting, whereas the latter are used for network planning and optimization purposes. Depending on the involved network entities, events can be classified in external or internal events.

External events include signaling messages that eNBs exchange with other network elements e. Internal events include vendor-specific information about the performance of the eNB.

After enabling trace collection, UEs transfer their event records to their serving eNB. Figure 2: Architecture for trace reporting. The structure of events consists of a header and a message container including different attributes referred to as event parameters. The header contains general attributes associated with the event description, such as the timestamp, the eNB, the UE, the message type, or the event length, while the message container includes specific attributes associated with the message type.

Trace decoding is performed by a parsing tool that extracts the information contained on fields.

Then, traces are synchronized by merging files from different eNBs by event type and ROP and ordering events by the timestamp attribute. Thus, it is possible to link simultaneous events of the same type from different eNBs e.

Estimating Spectral Efficiency from Traces A method for building a link-layer abstraction model for LTE downlink from network measurements is proposed here. The model relates SINR to SE based on signal strength, traffic, and radio resource measurements obtained from the live network. In most vendors, this event is reported once at the end of each connection, so that there is a one-to-one mapping between traffic reports and connections.

Each measurement record includes the pilot signal level from 1 serving cell and up to 8 neighbor cells [ 34 ]. It can be configured to be reported periodically or event-triggered. In the former case, each connection can comprise many records of this event.

A measurement report is said to belong to a given connection if it is reported during such connection. Figure 3 illustrates an example of how these events are distributed within a call. A call starts with a connection setup and ends with a connection release.


While in a call, the UE may perform a handover between cells. Therefore, a call may contain more than one connection. A UE traffic event is reported at the end of each connection, while RRC measurements are generated periodically along a connection.

Figure 3: Example of events in a call. In the tables, subindex refers to the traffic report i.

Figure 4 shows the flow diagram of the proposed algorithm. In stage 1, the time distribution of cell load is calculated per cell as the percentage of used REs during a fixed time period based on the information in UE Traffic Report events.To tackle this problem, industry fora and standardization bodies set up activities in the field of Self-Organizing Networks SON while defining 4G networks [ 5 ].

Again, the screenshot in Figure 4 shows LTE link budget for the downlink assuming a 1 Mbps data rate antenna diversity and 10 MHz bandwidth. The cell range gives the number of base station sites required to cover the target geographical area. Whenever new cellular technology is considered for mass deployment hundreds of its RF parameters go through tuning process with a view to find out optimum value.

Even if more realistic values of SE could be obtained from simulations, these cannot capture all possible factors, which greatly vary from cell to cell and dynamically change with time. Currently, network planning and optimization is mostly based on performance counters and alarms in the network management system [ 7 — 9 ]. In [7] an attempt to provide analysis of LTE system performance from radio network planning aspects has been made.
