It often happens that, having dialed the number of the right person, we hear in response a very unpleasant phrase: "The subscriber is temporarily unavailable …" Immediately a completely logical question arises: "What happened?" What is the reason for the lack of communication with those who urgently need us? And if this situation is repeated quite often, it starts to annoy. So let's find out why this is happening?
Fast communication is the advantage of mobile technologies. During the connection of two phones, malfunctions can occur either due to a breakdown of the device or lack of contact. When transmitting a signal, the route between the user's device and the base station is the most vulnerable point. Depending on this distance, the signal level changes. In addition, the phrase "subscriber unavailable" you can hear if the mobile device is located
in the basement, elevator, in the back of buildings withthick walls and fittings or on the ground floor. Not the best place for mobile phones is a road tunnel and a stage. Here, too, the subscriber is often unavailable. In addition to these "radio-opaque" places, there are also a number of others.
Mobile operators build their networks often with insufficient margin of safety. 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), it is not possible to make a call due to the heavy load on the network. However, there are very few such days, and everyone is probably already used to this situation.
It often happens that the subscriber is unavailable due to the failure of the base station or maintenance work. In this case, the loads are transferred to neighboring bases. The latter are not designed for a large number of users. Therefore, the connection with the subscriber is lost.
Network congestion also happens due to operators' marketing campaigns. This may be an all-time low prices for certain services (low price for calls within the network). The result of such an event is overload and the inability to connect with the subscriber at some points.
How can this problem be solved? Additional equipment can cope with it. To prevent a voice from appearing announcing that the subscriber is temporarily unavailable, MTS, for example, supplies its stations with the most modern equipment that has enough resources. In addition, this company is reconfiguring existing networks. This is done due to the appearancenew 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, to improve service, base stations in new areas are placed as close as possible to the problem area.
No network is immune from failures, and if the subscriber is unavailable, maybe even for a long time, you should not panic or get annoyed. There are certain standards that operators must comply with. For example, successful connections should not fall below 95%. No one guarantees a 100% connection. But for the most part, operators provide a sufficient level of communication.
