Impact of Signaling Load on the UMTS Call Blocking/Dropping

— Radio resources in the third generation (3G) wireless cellular networks (WCNs) such as the universal mobile telecommunications system (UMTS) network is limited in term of soft capacity. The quality of a signaling service transmission depends on various factors (i.e., location, speed, and the environment of the user, power control, and variable data rate requirement), and has impact on quality of user data communications where the opposite order is also true. In this paper, we provide the first step to evaluate the impact that various signaling service types have on call blocking and ongoing call drop in the UMTS systems. The radio resource’s acquisition time for each signaling service type is calculated. The maximum number of sessions that a signaling service type can be transmitted simultaneously is estimated along with the converting value when the other signaling service type is transmitted instead. Our analysis reduces the computational complexity in the call admission contr...
