Base Station Subsystem (BSS)

By : Irvando Damanik

BSS is a system for managing connections between BTS and BSC in order to work properly. The BTS and the BSC communicate across the specified Abis interface, enabling operations between components that are made by different suppliers. The radio components of a BSS may consist of four to seven or nine cells. A BSS may have one or more base stations. The BSS uses the Abis interface between the BTS and the BSC. A separate high-speed line (T1 or E1) is then connected from the BSS to the Mobile MSC.

BSS consist of :

1. BTS is a component that connects directly with mobile phones to send and receive signals. BTS is main component in telecomunication GSM connections, where include basic component (microwave, antenna, servives rack,tower, etc.) Connections initiated from the mobile equipment will be received by the BTS via an antenna, then process it and after the identification will be communicated to other base stations in accordance with the call destination are connected by microwave.
2. BSC is a component to managing connection among BTS that connect one another.  BSC control the connection between BTS and MSC.
