GroupDRM: Group-Based Dynamic Resource Management Model in Wireless Network

摘要

In the field of wireless communications, Universal Mobile Tele communications System (UMTS) offers broadband data transmission for mobile computer and phone users. As a part of UMTS, the UMTS Terrestrial Radio Access Network (UTRAN) needs to deploy distributed resource management system to meet three key user operations: Apply, Locate and Release. The traditional resource management models are no longer suitable for the increasing user amount and dynamic these operations, and resource consumption is relatively large especially CPU. We propose a new group-based dynamic resource management model, called as GroupDRM, which can meet all demands. Comparing to the traditional static model and complete dynamic model, GroupDRM model greatly reduces the delay of apply. The model also shows its advantages over the traditional dynamic model on the performances of releasing, locating and resource consumption.
