ICS telecom EV is the first public safety network planning solution that combines network planning and optimization features including:
Public safety operators need a multiple technology tool compatible with TETRA, PMR and Public Safety LTE, and manage coverage, capacity, site parameters and neighbor planning and optimization.
ICS telecom EV offers all of this and features propagation models which perform coverage calculations to a high level of accuracy without the use of the automatic model tuning module.
A model which can be used at a calibration stage to improve the final AFP result when drive test measurements are available.
The main issue with TETRA network design is the ability to determinate the number and the location sites required to achieve the target coverage. The role of the RF planner will consist of finding the best candidates to provide service for users in a given area.
ICS telecom EV’s ‘Prospective planning’ function identifies the best locations for new sites for greenﬁeld and densiﬁcation scenarios. This function is based on coverage target assumption. After users (subscribers) have been generated, they will be used to automatically add sites and the connection to their parent Base station using different constraints. The TETRA network design is then automatically performed, taking into consideration the required criterion based on coverage threshold and traffic demand.
ATDI:Public safety made easy
TETRA is based on TDMA signal with time division of channels. To provide service to many terminals at a time, each sector will need to use use several TRx. So that, in the network planning process, it is necessary to optimize the physical parameters (azimuth, tilt, frequency channel) to improve the coverage and the quality of the network.
Once the preliminary coverage of the network has been performed, an automatic station parameters optimizing process can be carried out. This feature of ICS telecom EV can optimize individually or simultaneously: Antenna patterns, antenna height, Azimuth, Tilt and Power. From the traffic demand to be offered, ICS telecom EV will assign to each station the number of TRx required for each sector. And ICS telecom EV also offers an automatic frequency planning feature. From a predefined list or band of frequencies, an optimized frequency plan will be automatically assigned to the network, minimizing or even removing interfered areas.
ATDI: Ensuring networks run at full capacity
LTE mobile broadband should help emergency services with live mobile video, situation aware dispatching and remote diagnostics. Mission Critical Push to Talk (MCPTT) feature provides one-to-one and one-to-many voice communication services. Each public safety device sends traffic data to a dedicated mission critical push to talk server and the server then copies the traffic to all the recipients. Although the number of public safety users is significantly lower than regular subscribers in any commercial LTE network, the number of simultaneously active public safety users can be very high, especially in a relatively small area when a major incident occurs.
The ‘Parenting LTE’ feature of ICS telecom EV is based on a population of public safety users, with specific profiles and traffic demands defined. It will solve the issue of network traffic congestion (or low traffic QoS performance) by checking performance of each site, including hot spot areas. This function takes into account DL/UL coverage criterions, traffic assumptions and schedulers.
ATDI: throughput safety
The public safety solution based on LTE technology should support direct communication between public safety users when the devices are in high density and if the network does not work or where users are located in non-covered areas. Proximity Services allows two devices to communicate directly - without data routing through the EUTRAN network. 3GPP standardizes Proximity Services (ProSe) for those purposes. The range of proximity network depends on the strength of the received signal and the radio conditions, such as interference.
“Cluster assignment” functionality of ICS telecom EV creates connections between different public safetydevices with constraints such as the distance between 2 linked devices, the maximum number of devices per station and per cluster, with a way to sort the devices. The connections between two subscribers will be made if the power received is greater than the predefined threshold. Connections between Subscribers/Clusters and eNodeBs can be performed with the help of “Cluster Parenting” function, limited to the maximum number of devices allowed. The Prospective planning feature can also automatically add new cells to ensure connectivity for all devices that cannot be directly connected to any existing eNodeB.
