CHANNEL COMMON METHOD BETWEEN BASE STATION SECTOR AND FREQUENCY ASSIGNMENT OF CODE DIVISION MULTI-ACCESS SYSTEM

摘要

PURPOSE: A code division multi-access system is provided to sharply reduce number of a channel card to enhance a simple, a light, and a competitive power of the system CONSTITUTION: The channel common method between base station sector and frequency assignment of code division multi-access system includes four steps. A first step is to establish a traffic channel capable of accommodating for a call generation of a subscriber in a base station of CDMA system. A second step is to decide whether is common a channel between frequency assignments only or not. A third step is to when the channel is common only between the frequency assignments in the step divided for the sum of numbers of the traffic channel and the over head channel between each frequency assignment by the total channel number a channel card and find the channel card and the traffic channel and establish a channel card for the rest traffic channels and is common only between each frequency assignment. A fourth step is to sum of channel numbers of the traffic channel and the over head channel between each sector and channel numbers of the traffic channel and the over head channel of the frequency assignment, divide the sum by total channel number a channel card, find the channel card and the rest traffic card, and establish the channel card for the rest traffic channel to be common channel together between the frequency assignment and the sector when a channel common is together with the sector in a state which the traffic channel is established in the above step.
