Position of BTS in the CDMA
System
The Base Transceiver Station (BTS) connects a Mobile Station (MS) to the
mobile network in a mobile communications system through its radio
interface functionalities. It best reflects the radio transmission features in
a CDMA system.
BTSB (all-IP BTS), developed by ZTE Corporation, is an IP-based new
generation BTS that is designed to fill in the varying needs of our
customers. It features large capacity, abundant transmission modes and
high adaptability.
An all-IP network is made up of three parts: MS (Mobile Station), RAN
(Radio Access Network) and CN (Core Network).
MS: A mobile phone, mobile station or mobile terminal;
RAN: Located between MS and CN and connects these two parts. It
processes radio signals and consists of two parts: BSCB/PCF/IWF
(combined as BSCB) and BTS;
CN: Provides authentication at the network side and interfaces with a
public network.
As a member of the BTSB family, ZXC10 CBTS is special for its compact
structure, in addition to other advantages such as large capacity and high
integration level.
The position of BTS in Base Station Subsystem (BSS) is shown in Fig. 1.
