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…
What is BSIC and its use in GSM
BSIC=NCC+BCC In GSM system, each BTS is allocated with a color code, which is called BSIC. MS can identify two cells with the same BCCH by the help of BSIC….
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…
What is Use of LAC in GSM
Location Area Code（LAC) : To locate the location of MS, the whole area covered by each GSM PLMN is divided into different location areas. LAC is used to identify different…
What is MNC and MCC for GSM
MCC MNC – Telecom What is mcc and mnc :- Both are very first question in your mind when you start learning on telecom its basic behind numbering system in…
What is Network Identity Parameter CGI in GSM
Network identity parameters mainly include cell global identity (CGI) and base station identity code (BSIC). CGI=MCC+MNC+LAC+CI Once MS receives SYS INFO, it decodes the CGI information, and decides whether it…
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…
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…
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…
BCH,CCCH and DCCH Channel of GSM
BCH (Broadcast Channels) BCCH(Broadcast Control Channels) Downlink Only. Broadcast information of the serving cell (System Information). Transmitted on timeslot zero of BCCH carrier. Read only by idle mobile at least…
