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…
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….
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…
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…
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…
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…
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…
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…
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 (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…
GSM (Um) Air Interface This is the interface between the GSM mobile station and the GSM Base station. The Air interface (RF Interface) uses the Time Division Multiple Access (TDMA)…
