The Study on the Solutions for Blocking Problems of Radio Cells in GSM Mobile Communication System

on July 5th, 2012 by - Comments Off

The blocking problems of radio channels in Global System For Mobile Communication(GSM) mobile communication system have badly restricted service expansion for mobile service provider due to the increasing subscriber number, the reducing network construction investments, and the advancing customers requirements for quality of service (QoS). The effect by use of single means to handle blocking
