Method for sharing channels between base station sectors and frequency assignments in CDMA cellular systems

摘要

A method for reducing the number of channel cards in a base station by sharing channels between a plurality of frequency assignments and between a plurality of sectors of the base station during a traffic overload in a code division multiple access (CDMA) system of the type having a plurality of cells with each cell containing the sectors and each sector having a group of traffic channels and a group of frequency assignments to it that is same as the group of frequency assignments to other said sectors within that same cell, the method comprising the step of setting traffic channels to accommodate requests within the base station, the step of determining whether said set traffic channels are to be shared between the frequency assignments and/or between the sectors, in the event that the set channels are shared only between the frequency assignments, the step of determining the number of channel cards by calculatingin event that the set channels are shared between frequency assignments and between sectors, the step of determining the number of channel cards by calculatingwherein X represents the sum of the set traffic channels and the overhead channels, Y represents the number of FAs and W represents the number of total channels per each channel card, the step of setting the set channels to the channel cards, and sharing channels using the set channel card between the sectors and between frequency assignments.
