Network Color Code NCC for GSM

NCC is a part of BSIC. MS uses it to distinguish adjacent BTS that belong to different GSM PLMN. NCC is composed of 3 bits, with the range of 0 to 7. NCC and BCC together form the base station identity code (BSIC), transmitted on synchronous channel of each cell. In many cases, different GSM … Read more

What is Cell Identity CI in GSM

To uniquely identify each cell in the GSM PLMN, the network operator needs to allocate one code for each cell, which is the cell identity (CI). Cell identity, together with LAI, is used for identity of each cell in the world. CI is composed of 16 bits, The available range is 0~65535 Cell Identity (CI) … Read more

Timing Advance in GSM

Timing Advance in GSM Transmission delay is unavoidable in the radio interface. If the mobile station moves away from the base station during a call, the further distance the more delay. The uplink is as the same. If the delay is too high, the timeslots of the signal from a certain mobile station and that … Read more

How Voice Signal Processing in GSM

How Voice Signal Processing in GSM The radio channel is quite different from the wired channel. First, the radio channel has a distinct time-change characteristic. The radio channel is exposed to the air, so it is vulnerable to the  interferences in the air. The signal is influenced by various interferences, multi-path fading and shadow fading, … Read more

Hierarchical Structure of Um Interface in GSM

The first layer is the physical layer, which is marked as L1 and is the lowest layer. This layer provides the radio link needed in transmission of bit stream. It defines the radio access capability of the GSM system and provides the most fundamental radio channel (logical channel) for  the information transmission of higher-layer , … Read more
