Local Usage Details: A Complete Guide

Local usage details are the records that contain information on incoming and outgoing calls received from a particular number. Many telecom companies are using these details from their customers to generate bills.

On the other hand, law enforcement agencies use this information to investigate if they think it will be relevant to their work. Before accessing these LUDs, it is necessary to have a court order. But the standards are less stringent than personal searching properties like homes.

Want to know more about local usage details? If yes, keep reading this article to explore more about LUDs.

LUDs: Overview

The local usage provides basic information about the local calls received from a particular number. The phone companies use this information to apply appropriate rates and other details later.

However, a simplified version of the calls list is reproduced on the customer’s bill, providing information about outgoing toll calls. It will help people to understand the charges.

If a customer accepts to collect charges on an incoming call, the bill does not include the list of incoming calls. The outgoing calls occur within the local call area, and it is one of the areas where no toll applied may not be listed.

Law enforcement agencies have to access both landline and cell phone call details as a part of an investigation. Sometimes, customers may not be notified about the inspection of the phone records, depending on the regional laws.

What are the uses of Local usage details?

Local usage details play an essential role in the telecom industry, especially for billing and accounting purposes. The local phone call data may help identify contacts, track transactions and other aspects of an investigation.

Operators can ensure the revenue generated by extracting the LUDs, sending them to the billing system and creating the customer’s invoice. It represents the proof of the telecom service usage to the customers, required to track and manage profitability.

Nowadays, LUDs have been optimized to generate more information and reveal new mobility patterns. However, many telecom companies keep these local call details for varying lengths of time.

The company has an internal policy to keep call details long enough to address customer disputes by returning raw data. The law may require the companies to keep this information for a set length of time.

How are mobility patterns revealed?

LUDs are one of the handy resources to pinpoint people’s location. It comes with the timestamps of mobile communications and geographic coordinates of the cell towers. The location of a specific individual can be approximated with the help of this data.

However, a specific mobile number has many mobile communications in a day. Therefore, the movements of an individual can be traced through obtaining the sequence of location data recorded.

Further, it is possible to track the spatial-temporal distribution of a target population. However, using the local phone data in this way can be challenging.

  • The antenna locations do not allow pinpointing the accurate location of the phone users.
  • It required active phone usage for generating LUDs.
  • It is only capable of recording one position during mobile communication.

Despite all these challenges, proximity location provides excellent spatial patterns, reflecting population movement. Further, it gives a competitive advantage for solving humanitarian crises and generating business innovations.

LUDs importance for Covid-19

The spatial-temporal analysis sourced by LUDs is considered an essential input in a health crisis such as COVID-19. It is helpful for policy intervention, control of pandemic and resource allocation.

The reason behind using it is it provides an in-depth and quantitative understanding of population movement and transmission patterns over time.

Wrapping up

Local usage details are one of the ways phone companies can apply appropriate rates to their customers. However, law enforcement agencies are using this call recording information as an investigation.

Moreover, the subscriber’s position can also be approximated with this information. Also, the dynamics of population movements can be estimated, solving health crises such as COVID-19 by clearly understanding the virus patterns.
