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 ...” The logical question immediately arises: “What happened?” What is the reason for the lack of communication with those who urgently need us? And if a similar situation is repeated quite often, it starts to annoy. So let's find out why this happens?
Fast connectivity is an advantage of mobile technology. During the connection of two phones, malfunctions can occur either due to a breakdown of the device or in the absence of contact. When transmitting a signal, the route between the user's device and the base station is the most vulnerable spot. Depending on this distance, the signal level changes. In addition, you can hear the phrase “subscriber unavailable” if the mobile device is
in the basement, elevator, in the back of buildings with thick walls and fittings, or on the ground floor. Not the best place for mobile phones is a road tunnel and a stage. Here, too, very often the subscriber is unavailable. In addition to these "radio-opaque" places, there are also a number of others.
Mobile operators often build their networks with insufficient margin of safety. The reason is that it is not profitable, 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 the heavy load on the network. However, there are very few such days, and everyone is probably used to this situation.
It often happens that the subscriber is unavailable due to the failure of the base station or preventive maintenance. In this case, the load moves 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 occurs due to marketing campaigns of operators. This can be an unprecedentedly low price 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 is able to handle it. In order to prevent a voice from appearing 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 is reconfiguring existing networks. This is due to the emergence of new high-rise buildings, as well as neighborhoods.
Trying to cope with the phenomenon "the subscriber is unavailable", 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 located as close to the problem area as possible.
Not a single network is safe 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%. One hundred percent communication is not guaranteed by anyone. But for the most part, operators provide a sufficient level of communication.
