Where does the connection go, or Why do we hear: "subscriber is not available"?

Often happens that, typing the number of the right person, we hear in response a very unpleasant phrase: "The subscriber is temporarily unavailable ..." Immediately there is a completely logical question: "What happened?" What is the reason for the lack of communication with those who need us urgently? And if this situation is repeated quite often, it starts to irritate. So let's find out why this is so?

Fast communication is the advantage of mobile technology. During the connection of two telephones, malfunctions can occur either due to a breakdown of the device or when there is no contact. When transmitting a signal, the route between the user's device and the base station is the most vulnerable place. Depending on this distance, the signal level changes. In addition, the phrase "subscriber is not available" you can hear if the mobile device is located In the basement, elevator, in the depths of buildings with thick walls and fittings or on the first floor. Not the best place for mobile phones - a road tunnel and a driveway. Here too often the subscriber is unavailable. In addition to these "radio-opaque" places, there are a number of others.

Mobile operators are building their networks often with inadequate safety margins. The reason is that it is unprofitable, a large system with a small number of users is unprofitable. Therefore, especially on holidays (New Year, for example), there is no way to make a call due to a heavy load on the network. However, there are very few such days, and probably everyone has become accustomed to this situation.

It often happens that the subscriber is unavailable due to the failure of the base station or the provision of preventive maintenance. In this case, the loads go to neighboring bases. The latter are not designed for a large number of users. Therefore, communication with the subscriber is lost.

Overloading in the network also happens because of the marketing actions of operators. This can be an all-time low price for certain services (low price for calls within the network). The result of such an event is overload and the impossibility at some moments to connect with the subscriber.

How can you solve this problem? With it is able to cope with additional equipment. In order not to appear a voice informing that the subscriber is temporarily unavailable, MTS, for example, supplies its stations with the most modern equipment, which has enough resources. In addition, this company reconfigures the existing networks. This is done because of the appearance of new high-rise buildings, as well as microdistricts.

Trying to cope with the "subscriber unavailable" phenomenon, Beeline - another mobile operator - is also developing projects that improve the quality of the connection. In addition, in order to improve the service, the base stations in new areas are located as close to the problem zone as possible.

Not a single network is insured against failures, and if the subscriber is unavailable, maybe even a long time, do not panic or get irritated. There are certain standards in which operators must fit. For example, successful connections should not fall below 95%. Nobody guarantees 100% connection. But most operators provide a sufficient level of communication.
