Summary :

CDMA cellular land network (CCLN) consists of base stations connected to selector bank subsystem. In the case of considering only the voice traffics, CCLN can be designed based on E1/T1 physical line and HDLC protocol with fixed or variable length. However, it is necessary to support not only voice but also data traffics in CDMA cellular system. Thus, it is needed to use physical lines efficiently to increase bandwidth efficiency and transmission speed. However, the conventional CCLN has some problems that the bandwidth is wasted because each BTS has its own private line. In this paper, the method using Distributed Queue Dual Bus (DQDB) Metropolitan Area Network (MAN) as a CDMA interconnect subsystem (CIS) is considered, and the performances of conventional and proposed methods constructing CIS are analyzed by computer simulation. According to the simulation results, if the traffics from all mobile stations are uniformly distributed among all BTSs, the performances of both conventional and proposed methodology have turned out to be almost equal. However, the performance of methodology using the DQDB MAN is much better than that of conventional method, in the case that the traffics from all mobile stations are nonuniformly distributed.
