Speech or voice calls are obviously the primary function for the GSM cellular system. Although their performance is nowhere near the level of those provided by 3G, they are nevertheless still important and useful. Although technology has moved on significantly since the introduction of GSM as a 2G technology, it is still in widespread use as phones are low cost, and battery usage small enabling battery charge intervals to be often a week or more. Developed as part of the GSM specification, it has also been incorporated into other cellular technologies. GSM provides recommendations, not requirements.

The HLR is considered the most important database, as it stores permanent data about subscribers, including a subscriber's service profile, location information, and activity status.
One of the basic aims was to provide a system that would enable greater capacity to be achieved than the previous first generation analogue systems. The GSM specifications define the functions and interface requirements in detail but do not address the hardware. The switching system includes the following functional units. The reason for this is to limit the designers as little as possible but still to make it possible for the operators to buy equipment from different suppliers.

Later, if the mobile station makes a call, the VLR will have the information needed for call setup without having to interrogate the HLR each time.
To achieve this the speech is digitally encoded and later decoded using a vocoder. Ground-breaking attributes like the SIM card enabling the same number and account to be retained when the phone was upgraded along with aspects like international roaming gave it a significant lead over other systems.
