Tems umts dropped blocked call specifications

Single site Drive Test 2. Every software has a key to work properly. Completion of the call here implies the connection being complete for either party to exchange talks. The main reasons for dropped calls in mobile networks are lack of radio coverage Tems umts dropped blocked call specifications in the downlink or the uplinkradio interference between different subscribers, imperfections in the functioning of the network such as failed handover or cell-resellection attemptsoverload of the different elements of the network such as cellsetc.

In this post I am going to discuss what the differences between these two events are, and briefly explain how they can be handled by the mobile service provider. Some testing requires one phone and some other requires two or more.

In modern telecommunication systems, such as cellular networksthe call setup procedure may be very complex and the point at which a call is considered successfully connected may be defined in a number of ways, thus influencing the way the dropped-call rate is calculated.

As I mentioned about a wireless callit is not wireless in entirety and it has to access the wire-line network in order to reach the destination cell phone. A Blocked Call is an event that can occur only before the call is completed between the called and the calling parties. TRAI, on the other hand, had said that telecoms are earning huge amounts of revenue and can and should expand their investment in infrastructure.

The dropped-call rate is one of the key performance indicators KPI used by the network operators to assess the performance of their networks. Software and necessary files: This phenomenon depends on the entire network, the wireless channels on the calling end, the wire-line backbone network, the wireless channels on the destination end.

External antenna can minimize this problem. In many practical cases this definition needs to be further expanded with a number of detailed specifications describing which calls exactly are counted as dropped, at what stage of the call setup procedure a call is counted as connected, etc.

In mobile communication system drive testing should be used to collect real-time RF information from the field. Data collection Software This is the software through which field data will be collected. There may be other areas of the network that require temporary coverage during a certain time of the year e.

MapInfo has the ability to combine and display, on a single map, data from a variety of sources that are in different formats and projections.

Drive testing during the day will imitate the conditions as seen by subscribers, but may clog up the network if call analysis is being performed. So this is a catch 22 situation where the decision has to be made by the service provider depending on the traffic analysis and customer growth analysis made over the years.

A cellfile contains all the necessary information related to the site, like ID of that site, assigned frequencies of that site, direction of the antennas of that site etc. How many mobile phone should we use during DT depends on the types of DT. It still has to build the backbone wire-line network to support the calls but for now let us assume that this matter has been taken care.

DT laptop should be with good condition and configuration, like high speed processor and especially RAM volume should be more for smooth drive testing.

Dropped-call rate

Data cables Data cable depends upon the model of the mobile phone. Different types of drive test fulfill different types of requirement from the customer.

Generally when we use mobile phones inside the car during DT, there is an enormous possibility to get poor field data. Chargers are also compulsory to keep the phone always charged.

Even in events like the baseball matches, the service provider takes necessary actions to provide more wireless channels by process called Cell Sectoring or another process of turning on smaller and more cellular base station towers to cover the same area. It will also allow for certain test signals to be transmitted and tested, particularly when setting up a new site, without interrupting normal operation.

Drive testing during the night will allow a greater area to be surveyed due to the reduction in vehicular traffic jam. Also, the court said, there is no legal basis or explanation in the Regulations as to why the compensation has been limited to only three call drops.

Cell file We must load the cellfile into the data collection software. Types of drive Test Drive test can be performed in very many ways. Then we can easily find out our required sites form the map and also the roads to be covered for that site.

Changes in the environment continually affect network performance. To summarize things, a Blocked Call is something which occurs before the connection is complete between the called party and the calling party. This is an event that can occur only after the call is connected and the exchange of talks has started.3 g dropped & blocked call specifications 1 Introduction This document describes some of the typical dropped/blocked call classifications encountered during several RAN Tuning Projects for WCDMA networks.

the Radio Environment is not suitable for a good connection and therefore the dropped call occurs. Sometimes the. Events in tems products Time in seconds from reception of System Information Block Type 19 (UMTS) to reception of System Information Block on LTE.

Note in particular that a transition to state NULL can take place from any state following one of the events Blocked Call or Dropped Call; such state transitions are not shown in the diagram.

Sep 28,  · Hi I share you this doc. It explains with tems examples the calssification and how to understand the causes for block and dropped calls un TEMS ''Tems_UMTS_dropped & blocked call specifications!!!!

Proactive Call Drop Avoidance in UMTS Networks management strategy is to block data whenever a voice call is made, however, defeating the purpose of serving voice drop calls by identifying most relevant features and improve the reliability of serving voice and data simultaneously via.

A dropped call may be caused by different reasons, such as hand-off failure. The Agilent Drive Test Solutions application uses a combination of phone states and messages to determine a dropped call. Dropped calls are determined similarly to blocked.
